نسخه ۱.۱۰

نسخه ۱.۱۰.۰-بتا۰۱

۲۲ اکتبر ۲۰۲۵

androidx.compose.ui:ui-*:1.10.0-beta01 منتشر شد. نسخه 1.10.0-beta01 شامل این کامیت‌ها است.

تغییرات API

  • بهینه‌سازی برای ارسال تغییر فوکوس اضافه می‌کند. این قابلیت را می‌توان با isOptimizedFocusEventDispatchEnabled = false ( I919fb , b/449228515 ) غیرفعال کرد.
  • تمام APIهای لمس غیرمستقیم را به‌روزرسانی می‌کند تا از نام APIهای اشاره‌گر غیرمستقیم برای تطبیق با APIهای ورودی اشاره‌گر استفاده کنند. ( I238ce ، b/451607214 )
  • توابع valueOf TextDirection ، TextAlign ، Hyphens و FontSynthesis اکنون هنگام دریافت مقدار نامشخص، خطای IllegalArgumentException صادر می‌کنند. ( I07c67 )
  • CompositionDataTree.makeTree را به‌روزرسانی کنید تا به جای تابع پوششی، مقادیر پیش‌فرض را ارسال کند. ( Id64a6 ، b/445229688 )
  • APIهای قواعد تست createComposeRule ، createAndroidComposeRule و createEmptyComposeRule که پارامتر effectContext می‌پذیرند، پایدار هستند و پارامتر به طور پیش‌فرض روی EmptyCoroutineContext تنظیم شده است. ( If400c ، b/450540702 )
  • UnplacedStateAwareModifierNode به UnplacedAwareModifierNode تغییر نام داد ( I6a551 ، b/449719932 )
  • بهینه‌سازی ضبط محتوا را لغو کنید ( Ic000b ، b/442364065 )
  • پرچم ویژگی ComposeUiFlags.isRectManagerOffsetUsageFromLayoutCoordinatesEnabled اضافه شد. این پرچم بهینه‌سازی عملکرد را در جایی فعال می‌کند که درخواست‌های مختصات مانند LayoutCoordinates.positionInRoot() به جای پیمایش کل درخت در هر فراخوانی، از آفست‌های ذخیره‌شده‌ای که از قبل در RectManager داریم استفاده می‌کنند. ( Ieaadc )

رفع اشکالات

  • اکنون PlaceholderSpan به درستی از مقیاس‌بندی فونت غیرخطی برای اندازه‌گیری استفاده می‌کند ( Id2ead ، b/324462728 )
  • از ViewCompat برای انجام ثابت‌های بازخورد لمسی پشتیبانی‌شده در سطح پلتفرم استفاده کنید، و به پشتیبانی جایگزین آن برای ثابت‌های جدیدتر متکی باشید. ( Ib5a00 )

نسخه ۱.۱۰.۰-آلفا۰۵

۸ اکتبر ۲۰۲۵

androidx.compose.ui:ui-*:1.10.0-alpha05 منتشر شد. نسخه 1.10.0-alpha05 شامل این کامیت‌ها است.

رفع اشکالات

  • اشکالی که باعث می‌شد پاپ‌آپ‌های تو در تو به اشتباه در بالای صفحه قرار بگیرند، برطرف شد؛ اکنون آنها به درستی به پاپ‌آپ والد خود متصل می‌شوند. ( Id4603 ، b/191279752 )
  • مشکل بسته‌بندی فوکوس با سایر نماها در سلسله مراتب برطرف شد. ( I95223 ، b/446028624 )
  • فیلدهایی که پارامترهای درون‌خطی آنها در تابع بازرس در لامبداهای تولید شده توسط کاتلین ۲.۲.۲۰ ( I9855d ، b/447110005 ) وجود نداشت، رفع شدند.
  • سایه نام منابع تکمیل خودکار بین رابط کاربری و ماژول‌های پایه ( I5da5a ) را برطرف می‌کند.

مشارکت خارجی

  • شیء UiModes به AndroidUiModes تغییر نام داده شده است تا نشان دهد که ثابت‌های آن از API اندروید برداشته شده‌اند. ( Ia0a77 )

نسخه ۱.۱۰.۰-آلفا۰۴

۲۴ سپتامبر ۲۰۲۵

androidx.compose.ui:ui-*:1.10.0-alpha04 منتشر شد. نسخه 1.10.0-alpha04 شامل این کامیت‌ها است.

تغییرات API

  • نوع قانون تست Compose که پارامتر CoroutineContext را می‌پذیرد، به پایدار ارتقا یافته است. حاشیه‌نویسی آزمایشی حذف شده است و توسعه‌دهندگان دیگر نیازی به انتخاب برای استفاده از این API ندارند. ( I74e6e )
  • ComposeUiFlags.isRectTrackingEnabled حذف شد. این منطق همیشه فعال نیست. ( Id78df )
  • سربارگذاری درون‌خطی Updater#set منسوخ شد، زیرا مقدار ارائه شده را بیش از حد فشرده می‌کردند ( Id679e )
  • ویژگی معنایی onAutofillText به عنوان منسوخ علامت‌گذاری کنید. ( I6f81c )
  • UnplacedStateAwareModifierNode معرفی شد. این متد یک فراخوانی برگشتی ارائه می‌دهد که وقتی طرح‌بندی قبلی دیگر قرار داده نشده باشد، فراخوانی می‌شود. ( I8fdd8 , b/309776096 )
  • مستندات RetainObserver.onRetained اصلاح شد و RetainObserver.onUnused اضافه شد که منعکس‌کننده‌ی RememberObserver.onAbandoned است ( Ia6fc5 ).
  • تابع onVisibilityChangedNode() اضافه شده است که یک Modifier.Node تولید می‌کند که توسط Modifier.onVisibilityChanged() از طریق Delegation استفاده می‌شود و امکان گسترش این قابلیت را در Modifier.Node سفارشی شما فراهم می‌کند. ( I70d84 , b/443001320 )

رفع اشکالات

  • مشکلی که باعث می‌شد محتوای درون‌خطی هنگام قرارگیری در خط آخر متن چندخطی بیضی‌شکل، علیرغم وجود placeholder قبل از ناحیه بیضی‌شکل، رندر نشود، برطرف شد. ( I76aaf ، b/441829208 )

نسخه ۱.۱۰.۰-آلفا۰۳

۱۰ سپتامبر ۲۰۲۵

androidx.compose.ui:ui-*:1.10.0-alpha03 منتشر شد. نسخه 1.10.0-alpha03 شامل این کامیت‌ها است.

تغییرات API

  • نام DelegatableNode.invalidateLayoutForSubtree را به DelegatableNode.invalidateMeasurementForSubtree تغییر می‌دهد. ( I94257 ، b/430106107 )
  • تطبیق‌دهنده‌ی تکراریِ isInHiddenAccessibilitySubtree حذف می‌کند. ( I4476c ، b/443792965 )
  • ردیابی‌های پشته Compose مبتنی بر کلید گروهی را معرفی می‌کند که به طور پیش‌فرض برای همه برنامه‌های کوچک‌شده فعال هستند. نگاشت proguard برای این ردیابی‌ها توسط افزونه Gradle کامپایلر Compose از Kotlin 2.3.0 شروع می‌شود. ( Ifbcb5 )
  • Modifier.skipToLookaheadSize اکنون از یک لامبدا پیش‌فرض فعال استفاده می‌کند که فقط زمانی که انتقال مشترک فعال است، پرش اندازه را فعال می‌کند، همانند Modifier.skipToLookaheadPosition . ( Ibe0f5 ، b/432485585 )
  • ComposeUiFlags.isOutOfFrameDeactivationEnabled حذف شده است و این قابلیت اکنون همیشه فعال است. ( I421ed )
  • توابع کارخانه‌ای برای ایجاد نمونه‌های FillableData به شیء همراه منتقل کنید. به جای فراخوانی FillableData(value) ، از متدهای کارخانه‌ای جدید استفاده کنید: FillableData.createFrom(value) . ( I2e200 , b/441719650 )
  • یک گره اصلاح‌کننده جدید به نام BeyondBoundsLayoutModifierNode معرفی کنید تا طرح‌بندی فراتر از محدوده را برای جستجوی متمرکز انجام دهد. ( I39be1 ، b/416133658 )
  • FocusTargetModifierNode.requestFocus() وقتی خودش قابلیت فوکوس ندارد، فوکوس را به یکی از فرزندانش ارسال می‌کند. این اکنون با FocusRequester.requestFocus() و FocusRequesterModifierNode.requestFocus() سازگار است. اگر به این رفتار نیازی ندارید، پرچم ComposeUiFlags.isRequestFocusOnNonFocusableFocusTargetEnabled را در برنامه خود روی false تنظیم کنید. ( Icca5c ، b/436863604 )
  • اندازه پنجره مبتنی بر DP را در WindowInfo ارائه دهید ( I9322b ، b/424442112 )
  • پرچم isNestedScrollDispatcherNodeFixEnabled حذف شد. ( If451a )
  • پشتیبانی از مقادیر تاریخ در تکمیل خودکار در API FillableData اضافه شود. val dateMillisValue: Long برای بازیابی اطلاعات تاریخ اضافه شده است، و یک سازنده FillableData(dateMillisValue: Long) مربوطه برای ایجاد نمونه‌های FillableData مبتنی بر تاریخ اضافه شده است. ( Id072a )

مشارکت خارجی

  • شیء UiModes برای اعلان ثابت‌هایی که برای حاشیه‌نویسی UiMode استفاده می‌شوند، معرفی شده است ( I03cb8 )

نسخه ۱.۱۰.۰-آلفا۰۲

۲۷ آگوست ۲۰۲۵

androidx.compose.ui:ui-*:1.10.0-alpha02 منتشر شد. نسخه 1.10.0-alpha02 شامل این کامیت‌ها است.

تغییرات API

  • به‌روزرسانی FillableData برای پشتیبانی از اجزای غیرمتنی مانند دکمه‌های تغییر وضعیت و لیست‌ها، شامل مقادیر بولی و صحیح درون FillableData و سازنده‌های کارخانه‌ای برای ایجاد نمونه‌های بولی و لیستی از FillableData که به AutofillValue پلتفرم ترجمه می‌شوند. ویژگی و عمل معنایی مربوطه نیز اضافه شده است. ( Ia8105 ، Icc5cf )
  • در حالت غیر لمسی، سیستم نمایش، فوکوس اولیه/پیش‌فرض را به یکی از آیتم‌های قابل فوکوس روی صفحه اختصاص می‌دهد. این ویژگی به Compose اضافه شده است و می‌توان آن را با فعال کردن ComposeUiFlags.isInitialFocusOnFocusableAvailable فعال کرد. ( Ib9178 )
  • پرچم isPointerInteropFilterDispatchingFixEnabled حذف شد. ( Iaa589 )
  • پرچم isNestedScrollInteropPostFlingFixEnabled حذف شد. ( I2a756 )
  • تطبیق‌دهنده‌های معنایی isHiddenFromAccessibility() و isInHiddenAccessibilitySubtree() را اضافه کنید. ( I9f5a1 )
  • تابع runCurrent() به MainTestClock اضافه شد تا تمام وظایف مقرر در زمان‌بند اصلی اجرا شوند. این کار برای پشتیبانی از اجرای تست‌ها روی StandardTestDispatcher انجام می‌شود، جایی که وظایف به زمان‌بند اضافه می‌شوند و وقتی تأخیر 0 میلی‌ثانیه‌ای دارند، بلافاصله اجرا نمی‌شوند. می‌توان با ایجاد یک ComposeTestRule و ارسال یک StandardTestDispatcher StandardTestDispatcher کند. به طور پیش‌فرض، تست‌ها روی UnconfinedTestDispatcher اجرا می‌شوند، که در این صورت runCurrent() هرگز فراخوانی نخواهد شد.
  • پشتیبانی از اجرای تست‌ها روی StandardTestDispatcher اضافه شد. از لحاظ تاریخی، چارچوب تست با استفاده از UnconfinedTestDispatcher تنظیم می‌شد (و هنوز هم می‌شود)، که با محیط تولید تفاوت‌های ظریفی دارد. اکنون می‌توانید این تنظیم را با ایجاد StandardTestDispatcher خودتان و افزودن آن به effectContext هنگام ایجاد ComposeTestRule (یا هنگام فراخوانی runComposeUiTest ) تغییر دهید. ( I334d0 ، b/254115946 )
  • کد مربوط به ایجاد درخت گره‌ها از SlotTree را به‌روزرسانی کنید. ( I997d3 )

رفع اشکالات

  • رابط کاربری Compose اکنون RetainScopes آگاه از چرخه حیات را در اندروید نصب می‌کند. رفتار پیش‌فرض اکنون مقادیر -ed را در طول تغییرات پیکربندی retain می‌کند. ( Id4a09 ، b/177562901 )

مشارکت خارجی

  • قابلیتی به VelocityTracker اضافه شد تا سرعت یک اشاره‌گر را بر اساس رویدادهای اشاره‌گر ردیابی‌شده با استفاده از رفتار مختص پلتفرم محاسبه کند. ( I621e8 )

نسخه ۱.۱۰.۰-آلفا۰۱

۱۳ آگوست ۲۰۲۵

androidx.compose.ui:ui-*:1.10.0-alpha01 منتشر شد. نسخه 1.10.0-alpha01 شامل این کامیت‌ها است.

تغییرات API

  • پایین آوردن اشاره‌گر با ماوس یا تاچ‌پد در ComposeView اکنون اگر اشاره‌گر در محدوده گره فوکوس‌شده قرار نگیرد، فوکوس را به‌طور خودکار پاک می‌کند. این منجر به یک تجربه کاربری "tap-to-clear focus" می‌شود که بیشتر از رفتار فعلی هنگام استفاده از دستگاه‌های ورودی اشاره‌گر مورد انتظار است. این رفتار را می‌توان با یک AbstractComposeView.isClearFocusOnPointerDownEnabled API جدید غیرفعال کرد. ( I6322b ، b/282963174 )
  • رابط FillableData برای پشتیبانی از انواع مختلف کامپوننت‌های تکمیل خودکار، علاوه بر متن، معرفی کنید. ( If9bd2 )
  • API جدید برای فعال و غیرفعال کردن پویای عناصر مشترک که امکان در نظر گرفتن اینکه آیا از قبل یک انتقال عنصر مشترک در حال انجام وجود دارد یا خیر را نیز فراهم می‌کند. API جدید برای تنظیم محدوده‌های هدف جایگزین هنگامی که عنصر مشترک هدف در حین انتقال از بین می‌رود. API جدید برای به دست آوردن LayoutCoordinates یک LookaheadScope . ( I18dd4 ، b/409819304 ، b/395670637 )
  • برای کنترل آزمایش ارسال اعداد صحیح صحیح به اینتروفن اسکرول تو در تو، پرچم isNestedScrollInteropIntegerPropagationEnabled را معرفی کنید. ( If8316 )
  • تابع requestFocusForChildInRootBounds() به DelegatableNode اضافه شد تا فوکوس به فرزندی که با rect داده شده همپوشانی دارد، منتقل شود. ( I001ef )
  • پرچم‌های حذف‌شده عبارتند از: isOnScrollChangedCallbackEnabled ، isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled ، isFlingContinuationAtBoundsEnabled ، isAutomaticNestedPrefetchEnabled ، DragGesturePickUpEnabled ، isPointerInteropFilterDispatchingFixEnabled ، isNestedScrollInteropPostFlingFixEnabled ، isNestedScrollDispatcherNodeFixEnabled ( I36c18 )
  • حاشیه‌نویسی @CheckResult روی توابع یابنده و انتخابگر SemanticsNode اضافه شد تا استفاده از مقادیر برگشتی اجباری شود. ( I6f86e ، b/201652748 )
  • بهبود عملکرد فرآیند ضبط محتوا ( I3c7c0 )
  • معرفی CompositionLocal که می‌تواند برای اصلاح قلم‌موهای پر کردن موفق هایلایت Autofill استفاده شود. ( I52329 )
  • رابط کاربری جدید Interpolatable معرفی شد که امکان درون‌یابی خودکار بین انواع مختلف را فراهم می‌کند، با فرض اینکه یک نوع می‌داند چگونه از نوع دیگر تبدیل کند. این رابط در چندین نوع نوشتن مانند Brush و Shape استفاده می‌شود، اما می‌تواند به صورت خارجی نیز مورد استفاده قرار گیرد. ( I58eab )
  • حالا Scrollable از رویدادهای اسکرول دوبعدی چرخ ماوس بهتر پشتیبانی می‌کند. یک API تست جدید برای کمک به موارد استفاده آزمایشی در MouseInjectionScope ارائه شده است. ما همچنین یک overload جدید برای متدهای اسکرول در MouseInjectionScope و یک flag برای کنترل رفتار جدید به نام isMouseWheel1DAxisLockingEnabled ( I136df ) معرفی کرده‌ایم.
  • اضافه کردن DeviceConfigurationOverrides برای نوع و وضعیت صفحه کلید، نوع و وضعیت ناوبری، وضعیت صفحه لمسی و نوع حالت رابط کاربری ( I282f0 )
  • یک LineHeightStyle.Mode جدید به نام Tight اضافه شد. این حالت به اعمال ارتفاع خطوط کوچکتر کمک می‌کند، حتی زمانی که ممکن است گلیف‌های بلندتر را حذف کنند. ( Id3849 )
  • BaselineShift اکنون یک مقدار نامشخص برای جلوگیری از boxing دارد. BaselineShift ، Hyphens ، LineBreak ، TextAlign و TextDirection اکنون دارای توابع کمکی isSpecified هستند. Hyphens ، TextAlign ، TextDecoration و TextDirection اکنون دارای متدهای valueOf() و value هستند که امکان serialization/deserialization کارآمد را فراهم می‌کنند. ( I8d44c )
  • یک رابط متد getDisplayName جدید اضافه شد تا امکان نمایش نام‌های نمایشی سفارشی برای نمونه‌های پارامتر پیش‌نمایش فراهم شود. ( I19bdf ، b/241699422 )
  • وقتی مقادیر Dp با استفاده از مقادیر کمتر از یا بیشتر از با مقادیر نامشخص (Unspecified) مقایسه می‌شوند، اکنون همیشه مقدار نادرست (false) را برمی‌گرداند. استفاده از Dp.compareTo(Unspecified) همیشه مقدار ۰ را برمی‌گرداند. تنظیم پرچم ComposeUiUnitFlags.isDpCompareToChanged به false Dp.compareTo() را به رفتار قبلی برمی‌گرداند، جایی که مقایسه Unspecified با کمتر از و بزرگتر از همیشه مقدار نادرست (false) را برنمی‌گرداند، و compareTo() با Unspecified با رفتار Float.compareTo() مطابقت دارد. ( Ifa88b , b/429221319 )

رفع اشکالات

  • انتقال minSdk پیش‌فرض از API 21 به API 23 ( Ibdfca ، b/380448311 ، b/435705964 ، b/435705223 )
  • مشکلی که مانع از ایجاد AndroidComposeViews جدید در حین انتقال می‌شد، برطرف شد. ( I2e23e , b/340894487 , b/287484338 )
  • اشکال رنگ هنگام استفاده از یک بردار قابل ترسیم که از یک رنگ استفاده می‌کند و fillColor نه کاملاً مات است و نه کاملاً شفاف، برطرف می‌شود. ( I3b041 ، b/328677973 )
  • مشکلی که باعث می‌شد آیکون‌های بارگذاری شده از طریق painterResource با رنگ‌های مخصوص تم، با تغییرات تم به‌روزرسانی نشوند، برطرف شد. ( I85ea0 ، b/424416571 )
  • معرفی مفاهیم onFillData و fillableData ( I45d9e )
  • رمزگذاری وضعیت مختص پلتفرم اکنون همیشه در StateRestorationTester فعال است. این امر رفتار تست را با بازیابی وضعیت واقعی برنامه، مانند Parcelization در اندروید، همسو می‌کند. ( I38211 ، b/408154192 ، b/382294247 )
  • رفع کرش‌های گاه به گاه هنگام درخواست فوکوس. ( 57b31a11 ، b/431111149 )

نسخه ۱.۹

نسخه ۱.۹.۴

۲۲ اکتبر ۲۰۲۵

androidx.compose.ui:ui-*:1.9.4 منتشر شد. نسخه ۱.۹.۴ شامل این کامیت‌ها است.

رفع اشکالات

  • مشکلی که باعث می‌شد محتوای متن درون‌خطی در آخرین خط یک متن چندخطی بیضی‌شکل ناپدید شود، حتی اگر محتوای درون‌خطی در ناحیه بیضی‌شکل نبود، برطرف شد. ( I76aaf ، b/441829208 )
  • مشکلی که باعث می‌شد وقتی debounceMillis صفر نیست، همیشه فراخوانی‌های اصلاح‌کننده onLayoutRectChanged انجام نشود، برطرف شد. ( 72aba47 , b/445324854 )

نسخه ۱.۹.۳

۸ اکتبر ۲۰۲۵

androidx.compose.ui:ui-*:1.9.3 منتشر شد. نسخه ۱.۹.۳ شامل این کامیت‌ها است.

رفع اشکالات

  • اشکالی که باعث می‌شد اصلاح‌کننده‌های onVisibilityChanged/onFirstVisible/onLayoutRectChanged در صورت وجود بیش از ۱۷۰ فرزند در طرح‌بندیِ در حال انتقال، فراخوانی مجدد دریافت نکنند، برطرف شد. ( 4f2fdd ، b/445356774 )

نسخه ۱.۹.۲

۲۴ سپتامبر ۲۰۲۵

androidx.compose.ui:ui-*:1.9.2 منتشر شد. نسخه ۱.۹.۲ شامل این کامیت‌ها است.

رفع اشکالات

  • Modifier.onVisibilityChanged() اکنون هنگام جدا شدن یا استفاده مجدد از یک گره، به درستی اجرا می‌شود. ( Ic5ce20 )
  • Modifier.onVisibilityChanged() و onLayoutRectChanged() اکنون با استفاده از placeWithLayer() برای قرار دادن فرزندان، طرح‌بندی‌های والد را به درستی مدیریت می‌کنند. ( Ia05ac9 )
  • برای Modifier.onVisibilityChanged() و onLayoutRectChanged() ، در موارد حساس مانند حذف یک لایه/اصلاح‌کننده لایه یا به‌روزرسانی ویژگی‌های لایه، به درستی اطلاع‌رسانی کنید. ( Ia05ac )

نسخه ۱.۹.۱

۱۰ سپتامبر ۲۰۲۵

androidx.compose.ui:ui-*:1.9.1 منتشر شد. نسخه ۱.۹.۱ شامل این کامیت‌ها است.

رفع اشکالات

  • اشکال رنگ هنگام استفاده از یک بردار قابل ترسیم که از یک رنگ استفاده می‌کند و fillColor نه کاملاً مات است و نه کاملاً شفاف، برطرف می‌شود. ( I3b041 ، b/328677973 )

نسخه ۱.۹.۰

۱۳ آگوست ۲۰۲۵

androidx.compose.ui:ui-*:1.9.0 منتشر شد. نسخه 1.9.0 شامل این کامیت‌ها است.

تغییرات مهم از زمان ۱.۸.۰

  • تغییرات مهم در نسخه ۱.۹.۰ در این پست وبلاگ پوشش داده شده است.
  • بررسی‌های Lint که با Compose ارائه می‌شوند، اکنون به حداقل نسخه AGP 8.8.2 نیاز دارند. اگر نمی‌توانید AGP را ارتقا دهید، می‌توانید Lint را با استفاده از android.experimental.lint.version=8.8.2 (یا نسخه جدیدتر) در gradle.properties خود، به تنهایی ارتقا دهید. برای اجرای بررسی‌های Lint در Compose در داخل IDE، به Android Studio Ladybug یا جدیدتر نیاز است.
  • تغییر اساسی: گره‌های اصلاح‌کننده‌ی graphicsLayer اکنون SemanticsModifierNode پیاده‌سازی می‌کنند. این می‌تواند منجر به SemanticsNodes جدیدی شود که به درخت معنایی اضافه می‌شوند و بنابراین، در تست‌هایی که فرضیاتی در مورد ساختار درخت معنایی دارند، منجر به شکست تست می‌شوند. به عنوان مثال، تست‌هایی که onChild ، onParent ، onSibling و سایر روش‌های مشابه برای ایجاد assertion استفاده می‌کنند، در صورت اضافه شدن یک گره جدید بین گره‌های فعلی و هدف، می‌توانند شکست بخورند. راه ترجیحی برای رفع این شکست‌ها، اضافه کردن مستقیم یک testTag به گره هدف است. رویکرد دیگر، استفاده از یک تطبیق‌دهنده‌ی آزادتر، مانند onNode(hasAnyAncestor(hasText("ancestor")) and hasText("target")) . ( I638b5 )

نسخه ۱.۹.۰-rc01

۳۰ ژوئیه ۲۰۲۵

androidx.compose.ui:ui-*:1.9.0-rc01 منتشر شد. نسخه 1.9.0-rc01 شامل این کامیت‌ها است.

رفع اشکالات

  • مشکلی که باعث می‌شد آیکون‌های بارگذاری شده از طریق painterResource با رنگ‌های مخصوص تم، با تغییرات تم سیستم به‌روزرسانی نشوند، برطرف شد. ( I85ea0 ، b/424416571 )
  • خطاهای مربوط به API های ۲۱ (Lollipop) و ۲۸ (Pie) که در آنها متدهای گرافیکی مهم هنگام بهینه‌سازی تغییر نام داده شده بودند، برطرف شد. ( Iebf99 ، b/425120571 ، b/420462749 )
  • مطمئن شوید که اصلاح‌کننده‌های onLayoutRectChanged به تازگی وارد شده‌اند، در ابتدا فراخوانی شوند. ( l9aa91 )، ( lb348a )
  • رفع مشکل نامعتبر شدن نادرست حافظه پنهان آفست که باعث می‌شد اصلاح‌کننده‌های onLayoutRectChanged با مختصات اشتباه ( ibd4cd ) و ( lddc57 ) فراخوانی شوند.
  • رفع مشکل دریافت مختصات نادرست توسط اصلاح‌کننده‌های onLayoutRectChanged برای طرح‌بندی‌های چرخانده/کج‌شده ( lddc57 ، b/426750475 )

مشارکت خارجی

  • مشکلی که باعث می‌شد آیتم‌های dragAndDropSource در LazyList هنگام اسکرول ناپدید شوند، برطرف شد. با تشکر از ویکتور رندینا! ( dc3bcd3 ، b/425894792 )

تغییرات API

  • شیء همراه را به کلاس آزمایشی برای مطابقت تغییر می‌دهد. ( I8452a )
  • پرچم آزمایشی isTrackFocusEnabled ( I003fd ) حذف شد

رفع اشکالات

  • وقتی هیچ WindowInsets به محتوای ComposeView نفوذ نکند، مقادیر WindowInsetsRulers ارائه نمی‌شوند. ( I71221 )

نسخه ۱.۹.۰-بتا۰۱

۱۸ ژوئن ۲۰۲۵

androidx.compose.ui:ui-*:1.9.0-beta01 منتشر شد. نسخه 1.9.0-beta01 شامل این کامیت‌ها است.

تغییرات اساسی

  • گره‌های اصلاح‌کننده‌ی graphicsLayer اکنون SemanticsModifierNode پیاده‌سازی می‌کنند. این می‌تواند منجر به SemanticsNodes جدیدی شود که به درخت معنایی اضافه می‌شوند و بنابراین، در تست‌هایی که فرضیاتی در مورد ساختار درخت معنایی دارند، منجر به شکست تست می‌شوند. به عنوان مثال، تست‌هایی که onChild ، onParent ، onSibling و سایر روش‌های مشابه برای ایجاد assertion استفاده می‌کنند، در صورت اضافه شدن یک گره جدید بین گره‌های فعلی و هدف، می‌توانند شکست بخورند. راه ترجیحی برای رفع این شکست‌ها، اضافه کردن مستقیم یک testTag به گره هدف است. رویکرد دیگر، استفاده از یک تطبیق‌دهنده‌ی آزادتر، مانند onNode(hasAnyAncestor(hasText("ancestor")) and hasText("target")) است. ( I638b5 )

تغییرات API

  • ShadowContext به یک رابط مهر و موم شده تغییر یافت ( I3ce40 )
  • یک روش بین ماژولی برای ایجاد یک رویداد لمس غیرمستقیم (برای آزمایش) اضافه می‌کند ( I22e4c )
  • IndirectTouchEvent.nativeEvent را آزمایشی می‌کند. ( I6fda5 )
  • سطح API را بر اساس بازخورد شورای API اصلاح می‌کند. ( Ibf378 )
  • ثابت FrameRateCategory.NoPreference را حذف کنید. نام Modifier.requestedFrameRate را به Modifier.preferredFrameRate تغییر دهید. ( I2f976 )
  • WindowInsetsRulers : rulersIgnoringVisibility به حداکثر تغییر یافت. getDisplayCutoutBounds() به یک تابع الحاقی از PlacementScope تبدیل شد. تابع WindowInsetsAnimationProperties به WindowInsetsAnimation و تابع getAnimationProperties() به getAnimation() تغییر یافت. ( I3816f )
  • کلاس ShadowParams به Shadow ( I11cca ) تغییر یافت.
  • بسته‌ی مربوط به API نرخ فریم را از androidx.compose.ui.ui به androidx.compose.ui ( I8994e ) تغییر دهید.
  • InsetsRulers تغییر داده شد تا در کد مشترک با نام WindowInsetsRulers باشد. API ساده شد تا همه insets ها WindowInsetsRulers باشند. ویژگی‌های انیمیشن غیر خط‌کشی را در یک کلاس AnimationProperties استخراج کرد. WindowInsetsRulers.innermostOf() می‌تواند برای ادغام چندین WindowInsetsRulers استفاده شود. ( I2f0c6 , b/415012444 )
  • یک API ابزاری برای تجزیه اطلاعات منبع اضافه شده توسط کامپایلر Compose اضافه شد. ( Iceaf9 ، b/408492167 )

رفع اشکالات

  • اکنون که این ویژگی به طور کامل تأیید شده است، پرچم isGetFocusedRectReturnEmptyEnabled حذف شده است. ( Ife722 )
  • اشکالی در performScrollToNode برطرف شد که در برخی موارد به گره هدف نمی‌رسید. با این اصلاح، در آن موارد باید همیشه به گره هدف برسد. یکی از عوارض جانبی این تغییر این است که موقعیت دقیق اسکرول در انتهای عمل اکنون ممکن است متفاوت باشد، که بر تست‌های اسکرین‌شات و تست‌هایی که در مورد موقعیت دقیق اسکرول فرض می‌کنند، تأثیر می‌گذارد. ( I2c8a1 )

نسخه ۱.۹.۰-آلفا۰۴

androidx.compose.ui:ui-*:1.9.0-alpha04 منتشر شد. نسخه 1.9.0-alpha04 شامل این کامیت‌ها است.

تغییرات API

  • APIهای اصلاح‌کننده برای سایه‌های قابل تنظیم اضافه شد. ( I2058d ، b/160665122 )
  • یک ویژگی SemanticsModifierNode.isImportantForBounds اضافه کنید که تعیین می‌کند آیا گره هنگام محاسبه مرزها باید در نظر گرفته شود یا خیر. این ویژگی به طور پیش‌فرض true است و می‌توان آن را روی false تنظیم کرد تا نشان دهد که گره نباید برای مرزها در نظر گرفته شود. ( I7ebec )
  • یک تابع کارخانه‌ای SemanticsPropertyKey برای اعلان ویژگی‌های معنایی مختص اندروید اضافه کنید که به عنوان اضافات دسترسی از طریق AccessibilityNodeInfo.getExtras در دسترس قرار می‌گیرند. ( I2ed51 )
  • کاربردهای ComposeUiFlags.isRemoveFocusedViewFixEnabled حذف و پرچم ( I50328 ) منسوخ شد.
  • معرفی چارچوب سایه قابل تنظیم جدید. این شامل DropShadowPainter و InnerShadowPainter و همچنین وابستگی‌های DropShadow/InnerShadow می‌شود. زیرساخت سایه به گونه‌ای به اشتراک گذاشته شده است که سایه‌های تولید شده یکسان می‌توانند در چندین سایت تماس به اشتراک گذاشته شوند، بدون اینکه نیاز به تولید مجدد سایه‌ها به تعداد n بار باشد. ( I24f7a ، b/160665122 )
  • CompositeShader و CompositeShaderBrush را معرفی کنید که یک نتیجه ترکیبی بین دو سایه‌زن ایجاد می‌کنند. همچنین ShaderBrush#transform برای تنظیم ماتریس تبدیل برای سایه‌زن اضافه کنید. ( I2621a ، b/160665122 )

رفع اشکالات

  • اشکالی در NestedScrollInteropConnection که در آن متدهای fling نسبت به نماها در ترتیب نادرستی قرار می‌گرفتند، برطرف شد ( I56ad4 )
  • پیش از این، دیالوگ‌هایی که تمام صفحه نمایش داده می‌شدند، در ناحیه برش نمایشگر رسم نمی‌شدند. این اشکال برطرف شده است، به طوری که دیالوگ‌هایی با decorFitsSystemWindows = false و usePlatformDefaultWidth = false می‌توانند ناحیه برش نمایشگر را در نظر بگیرند. ( I9e975 )
  • اشکالی که باعث می‌شد نشانگر فوکوس سبز TalkBack پس از روشن شدن در حالی که برنامه Compose در پس‌زمینه است، رسم نشود، برطرف شد. ( Ifd12a )

نسخه ۱.۹.۰-آلفا۰۳

۲۰ مه ۲۰۲۵

androidx.compose.ui:ui-*:1.9.0-alpha03 منتشر شد. نسخه 1.9.0-alpha03 شامل این کامیت‌ها است.

تغییرات API

  • تابع Flag ComposeUiFlags.isGetFocusedRectReturnEmptyEnabled باعث می‌شود وقتی هیچ چیزی در ComposeView قابل فوکوس نیست، مقدار rect روی Empty تنظیم شود. این کار مانع از انتخاب View برای فوکوس در جستجوی focus می‌شود. این امر به ویژه برای زمانی که یک IME گزینه NEXT دارد که ممکن است سعی کند روی ComposeView فوکوس کند و requestFocus() با شکست مواجه می‌شود، مهم است. ( Ibd0e2 , b/369256395 )
  • پرچم isNestedScrollDispatcherNodeFixEnabled را معرفی کنید. ( I0d24a )
  • تغییر نام DialogProperties از dialogContentTitle به windowTitle ( Ibd27b )
  • اصلاح‌کننده‌های Modifier.onFirstVisible و Modifier.onVisibilityChanged معرفی شدند که اصلاح‌کننده‌های سطح بالایی هستند که بر روی Modifier.onLayoutRectChanged ساخته شده‌اند. این اصلاح‌کننده‌ها به‌طور خاص برای مدیریت بسیاری از نیازهای رایج برنامه‌ها مانند ثبت نمایش‌ها، پخش خودکار ویدیوها و غیره ساخته شده‌اند. این اصلاح‌کننده‌ها با در نظر گرفتن عملکرد ساخته شده‌اند تا بتوان از آنها در سناریوهای حیاتی مبتنی بر لیست بدون خطر کاهش عملکرد اسکرول استفاده کرد. علاوه بر این APIهای اصلاح‌کننده، APIهای اضافی به RelativeLayoutBounds اضافه شده‌اند تا از این موارد استفاده پشتیبانی کنند و همچنین ایجاد اصلاح‌کننده‌های سفارشی مشابه را که دقیقاً متناسب با مورد استفاده آنها هستند، برای توسعه‌دهندگان آسان‌تر کنند. ( I759b8 )
  • برای در نظر گرفتن توسعه‌های آینده این ویژگی، setDiagnosticStackTraceEnabled به آزمایشی تغییر دهید. ( I11db3 )
  • معرفی Modifier.scrollable2D ، Scrollable2DState و APIهای همراه برای ایجاد حالت. همچنین توابع افزونه اسکرول رایج معرفی شدند. ( Ic61c8 ، b/214410040 )
  • مقادیر رنگ ۶۴ بیتی Compose مستقیماً با Android ColorLongs قابل مقایسه نیستند زیرا شناسه‌های فضای رنگ برای برخی از فضاهای رنگ نامرتب هستند. برای تبدیل به و از فضاهای رنگ اندروید، دو API جدید اضافه شده‌اند: toColorLong() و fromColorLong() . ( I36899 )
  • ViewConfiguration.minimumFlingVelocity برای کنترل سرعت پرتاب با حد پایین معرفی شد. ( I11aab )

نسخه ۱.۹.۰-آلفا۰۲

۷ مه ۲۰۲۵

androidx.compose.ui:ui-*:1.9.0-alpha02 منتشر شد. نسخه 1.9.0-alpha02 شامل این کامیت‌ها است.

تغییرات API

  • dialogContentTitle به DialogProperties اضافه کنید، که عنوان پنجره محتوا را تنظیم می‌کند. bf9d670

رفع اشکالات

  • خط‌کش‌های پنجره‌های داخلی موقتاً غیرفعال شده‌اند تا تست‌های داخلی اصلاح شوند. 8d1402
  • نحوه اضافه شدن تغییرات ورودی اشاره‌گر به VelocityTracker در DragGestureNode اصلاح شد، این مورد را می‌توان با پرچم جدید isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled کنترل کرد. 254ddb

نسخه ۱.۹.۰-آلفا۰۱

۲۳ آوریل ۲۰۲۵

androidx.compose.ui:ui-*:1.9.0-alpha01 منتشر شد. نسخه 1.9.0-alpha01 شامل این کامیت‌ها است.

تغییرات رفتاری

  • بررسی‌های Lint که با Compose ارائه می‌شوند، اکنون به حداقل نسخه AGP 8.8.2 نیاز دارند. اگر نمی‌توانید AGP را ارتقا دهید، می‌توانید Lint را با استفاده از android.experimental.lint.version=8.8.2 (یا نسخه جدیدتر) در gradle.properties خود، به تنهایی ارتقا دهید. برای اجرای بررسی‌های Lint در Compose در داخل IDE، به Android Studio Ladybug یا جدیدتر نیاز است.

تغییرات API

  • پرچم را حذف می‌کند تا دستورات ردیابی برای ردیاب مسیر برخورد (اشکال‌زدایی) فعال شوند. ( I1b2a1 )
  • InnerRectRulers و OuterRectRules به متد تبدیل شدند. پارامتر نام از API عمومی RectRulers حذف شد. DerivedRulers اکنون یک گزینه سازنده برای Vertical و Horizontal Rulers است. MergedHorizontalRulers و MergedVerticalRulers با متدهای minOf و maxOf برای تولید نمونه جایگزین شده‌اند. ( Iee89f ، b/408192133 )
  • androidx.compose.ui.LocalSavedStateRegistryOwner به نفع androidx.savedstate.compose.LocalSavedStateRegistryOwner منسوخ کنید. ( I5439f ، b/377946781 )
  • یک Modifier.keepScreenOn اضافه کنید تا صفحه نمایش در حالت آماده به کار ( Ib5af4 ، b/408284174 ) به حالت خواب نرود.
  • یک ویژگی معنایی جدید Shape اضافه کنید، که می‌تواند زمانی تنظیم شود که شکل عنصر رابط کاربری با مستطیل اطراف آن متفاوت باشد، مثلاً مستطیل با گوشه‌های گرد. ( I1376f )
  • مشکل مربوط به ارسال رویداد اشاره‌گر در AndroidViews برطرف شد و پرچم isPointerInteropFilterDispatchingFixEnabled برای محافظت از تغییرات اضافه شد. ( I0e272 ، b/372055500 ، b/408002332 )
  • FocusRestorer دیگر مورد فوکوس‌شده قبلی را پین نمی‌کند. کاربران باید از یک کلید استفاده کنند تا مطمئن شوند که مورد فوکوس‌شده قبلی همان هش ترکیبی را دارد تا فوکوس با موفقیت بازیابی شود. ( I4203b , b/330696779 )
  • به Compose اجازه دهید تا ViewTreeObserver.OnScrollChanged را فعال کند. این رفتار تحت پرچم isOnScrollChangedCallbackEnabled معرفی شده است. ما همچنین یک تابع افزونه از DelegatableNode dispatchOnScrollChanged معرفی کرده‌ایم. ( I34b9d , b/238109286 )
  • currentCompositeKeyHash اکنون منسوخ شده است. به جای آن از currentCompositeKeyHashCode استفاده کنید. API جایگزین، هش یکسانی را با بیت‌های بیشتر رمزگذاری می‌کند، که به صورت نمایی احتمال اینکه دو گروه تصادفی نامرتبط در سلسله مراتب ترکیب، کلید هش یکسانی داشته باشند را کاهش می‌دهد. ( I4cb6a , b/177562901 )
  • پروژه‌های منتشر شده با کاتلین ۲.۰ برای استفاده به KGP 2.0.0 یا جدیدتر نیاز دارند ( Idb6b5 )
  • پشتیبانی از بررسی پرز برای FocusRequester اضافه شد تا مطمئن شویم که در داخل ترکیب به خاطر سپرده می‌شود ( I6bf91 )
  • قابلیت تنظیم نرخ فریم ترجیحی یا دسته‌بندی نرخ فریم در Composable که باید در ( Ie5201 ) رندر شود، اضافه شد.
  • نمایش MotionEvent بومی در اندروید. ( I17286 )
  • getChecked() + setChecked(int) اضافه کنید، isChecked + setChecked(boolean) منسوخ کنید ( Iaac9d )
  • اصلاح‌کننده‌ی graphicsLayer اکنون یک blendMode و یک colorFilter ( Iab0e6 ) را می‌پذیرد.
  • ترکیب LocalResources به صورت محلی برای پرس‌وجوی منابع اضافه شد. فراخوانی LocalResources.current با تغییر پیکربندی، دوباره ترکیب می‌شود، بنابراین فراخوانی‌های API مانند stringResource() مقادیر به‌روز شده را برمی‌گردانند. ( I50c13 ، b/274786917 )
  • ارائه API آزمایشی برای Composables جهت مدیریت رویدادهای لمس غیرمستقیم ( Icff57 )
  • این نسخه، گزارش خطاهای مدیریت نشده‌ای که در طول مراحل طرح‌بندی و ترسیم محتوای قابل ترکیب شما رخ می‌دهند را بهبود می‌بخشد. پیش از این، یک خطای شناسایی نشده در اینجا، اجرای تست را مختل می‌کرد و مجموعه تست را زودتر از موعد خاتمه می‌داد. اکنون می‌توان این خطاها را بدون پایان دادن به مجموعه تست، با ظرافت بیشتری گزارش کرد. ( I9928b ، b/314128080 )
  • API آزمایشی GlobalAssertions منسوخ شد. کاربرد مورد نظر آن اجرای بررسی‌های دسترسی‌پذیری بود، برای این منظور به enableAccessibilityChecks() مراجعه کنید. ( I50aa5 )
  • SemanticsNodeInteraction.performTextInputSelection دیگر آزمایشی نیست و اکنون از یک پارامتر اضافی relativeToOriginal پشتیبانی می‌کند که به شما امکان می‌دهد انتخاب را یا روی متن اصلی تبدیل نشده یا متن تبدیل شده اعمال کنید. ( I3a905 , b/261561038 , b/277018945 )
  • معرفی API برای ایجاد لیست‌های گلوله‌ای سفارشی از طریق AnnotatedString ( I1d066 ، b/383269496 ، b/139326648 )
  • runWithTimingDisabled به نفع runWithMeasurementDisabled منسوخ کنید، که رفتار را واضح‌تر توصیف می‌کند - همه معیارها متوقف می‌شوند. علاوه بر این، سوپرکلاس MicrobenchmarkScope در معرض دید قرار دهید زیرا تعریف مجدد تابع runWithMeasurementDisabled برای دسترسی آزاد امکان‌پذیر نیست، زیرا درون‌خطی است. ( I9e23b ، b/389149423 ، b/149979716 )
  • رابط کاربری ابزارهای دستگاه‌ها (UI-tooling Devices API) به‌روزرسانی شد تا دستگاه‌های جدیدتر را نیز شامل شود. ( Ia2ac1 )
  • حالت عمودی تبلت را به مجموعه اندازه‌های پیش‌نمایش صفحه اضافه کنید تا به توسعه‌دهنده کمک کنید پنجره‌های بزرگ‌تر را در نظر بگیرد ( Ia1976 )
  • معرفی API مقدار ردیابی برای علامت‌گذاری/ثبت ردیابی با مقادیر در یک نقطه زمانی مشخص. مقادیر ردیابی در Prefetto به عنوان یک خط جدید نشان داده می‌شوند که می‌توان از طریق جدول زمانی ردیابی آنها را مشاهده کرد. در اندروید، آنها با استفاده از Trace.setCounter پیاده‌سازی می‌شوند. ( Idcf48 )

رفع اشکالات

  • رفع مشکل ارسال ناظران یادآوری در ترکیب قابل مکث برای جلوگیری از ارسال موارد به خاطر سپرده شده/فراموش شده در یک درخواست ( I570b2 ، b/404645679 ، b/407931790 )
  • اکنون می‌توان android:dialogTheme طوری تنظیم کرد که وقتی decorFitsSystemWindows نادرست است ( I7922f ، b/246909281 ) ویژگی‌های کادر محاوره‌ای را کنترل کند.
  • اشکالی که باعث می‌شد هر رویداد حرکتی خارج از یک کادر محاوره‌ای، کادر محاوره‌ای را رد کند، برطرف شد. ( Ia78fd )
  • بررسی‌های lint در Compose اکنون به حداقل نسخه AGP 8.8.2 از خط فرمان و حداقل Android Studio Ladybug برای پشتیبانی از IDE نیاز دارند. اگر از نسخه قدیمی‌تر AGP استفاده می‌کنید، می‌توانید android.experimental.lint.version=8.8.2 در gradle.properties تنظیم کنید تا نسخه Lint را بدون تأثیر بر AGP ارتقا دهید. ( I6f2a8 )
  • یک ویژگی معنایی جدید به نام InputText اضافه شد که مقدار یک textfield را قبل از اعمال تبدیل خروجی دریافت می‌کند. ( Iae46a , b/395911609 , b/176949051 )
  • API مربوط به enableAccessibilityChecks() که بررسی‌های دسترسی‌پذیری اندروید را فعال می‌کند، بسته‌هایی را که در صورت عدم استفاده از TestRule compose:ui:ui-test-accessibility هستند و در هنگام فراخوانی TestRule ، compose:ui:ui-test-junit4-accessibility ، جدا می‌کند ( I3c318 ، b/391560768 ).
  • پشتیبانی از ردیابی پشته‌های نوشتن در LaunchedEffect و rememberCoroutineScope اضافه شد ( I705c0 ، b/354163858 )

مشارکت خارجی

  • تغییر تابع آزمایشی runComposeUiTest برای پذیرش یک بلوک suspend. همچنین یک fun منسوخ شده runComposeUiTest برای سازگاری باینری اضافه شد ( I3b88c ، b/361577328 )

نسخه ۱.۸

رفع اشکالات

  • رفع برخی مشکلات با onLayoutRectChanged و LazyLayout d791b11
  • درخواست‌های اندازه‌گیری مجدد برای موارد از پیش تنظیم‌شده را نادیده بگیرید. این اشکال بر عملکرد پیمایش طرح‌بندی‌های تنبل تأثیر گذاشت زیرا پیش‌واکشی در برخی موارد به طور مؤثر کار نمی‌کرد و اندازه‌گیری در داخل قاب اتفاق می‌افتاد. 742087a

نسخه ۱.۸.۰

۲۳ آوریل ۲۰۲۵

androidx.compose.ui:ui-*:1.8.0 منتشر شد. نسخه ۱.۸.۰ شامل این کامیت‌ها است.

تغییرات مهم از زمان ۱.۷.۰

  • Compose 1.8 شامل پشتیبانی جدیدی برای تکمیل خودکار معنایی است. مطمئن شوید که نسخه‌های UI و Foundation که استفاده می‌کنید نسخه ۱.۸ یا بالاتر هستند، زیرا تکمیل خودکار برای اجزای متنی به آخرین نسخه‌های هر دو ماژول نیاز دارد. برای استفاده از API و مثال‌ها، لطفاً برای جزئیات بیشتر به مستندات تکمیل خودکار، اینجا مراجعه کنید.
  • Compose 1.8 از انواع دیگری از بازخورد لمسی پشتیبانی می‌کند: Confirm ، ContextClick ، GestureEnd ، GestureThresholdActivate ، Reject ، SegmentFrequentTick ، SegmentTick ، ToggleOn ، ToggleOff ، VirtualKey . این قابلیت از طریق LocalHapticFeedback قابل دسترسی است و در اندروید، این قابلیت به طور پیش‌فرض زمانی که Vibrator API پشتیبانی از لمس را نشان می‌دهد، در دسترس است.
  • APIهای چندگانه Focus اکنون پایدار هستند، از جمله Modifier.focusRestorer() و onEnter و onExit FocusProperties ( I6e667 ). اکنون می‌توانید هنگام فراخوانی requestFocus ، یک FocusDirection مشخص کنید. ما یک API requestFocus(FocusDirection) را به focusRequester و FocusTargetModifierNode اضافه کرده‌ایم تا امکان فوکوس با یک جهت خاص فراهم شود. (I5d9ec][https://android-review.googlesource.com/#/q/I5d9eca3a2cd283c1b84ad6b77d929ef9a49ce4cc], b/245755256 )

۲۹ ژانویه ۲۰۲۵

androidx.compose.ui:ui-*:1.8.0-beta01 منتشر شد. نسخه 1.8.0-beta01 شامل این کامیت‌ها است.

تغییرات API

  • ContextualFlowRow و ContextualFlowColumn به عنوان منسوخ علامت‌گذاری شده‌اند. این مؤلفه آزمایشی در نسخه ۱.۷ معرفی شده و هنوز تثبیت نشده است و پیاده‌سازی آن نامطلوب تشخیص داده شده است. در آینده، ممکن است مؤلفه‌ای ارائه شود که موارد استفاده‌ای را که این مؤلفه قرار بود حل کند، حل کند.
    • FlowRow و FlowColumn دارای overloadهای آزمایشی هستند که در نسخه ۱.۷ معرفی شده‌اند و شامل یک پارامتر overflow هستند. استفاده از این پارامتر منسوخ شده است و overloadهای بدون این پارامتر می‌توانند به جای آن استفاده شوند. رفتار پیش‌فرض "overflow" برای این overloadها، همانطور که از زمان معرفی آن بوده، "Clip" خواهد بود.
    • بسیاری از موارد استفاده برای ContextualFlowRow را می‌توان با استفاده از FlowRow انجام داد، اما اذعان داریم که این به طور کلی درست نیست. ContextualFlowRow کاملاً در فضای کاربر قابل پیاده‌سازی است و می‌توان پیاده‌سازی آن را کپی کرد و در صورت تمایل آن را تطبیق داد. در آینده، امیدواریم این موارد استفاده را به روشی متفاوت حل کنیم. ( Ibafec )
  • SemanticsNodeInteraction.semanticsId() حذف شده است. به جای آن SemanticsNodeInteraction.fetchSemanticsNode().id ( Ie397a )
  • API های قدیمی تکمیل خودکار منسوخ شده‌اند. به جای آن از API جدید مبتنی بر معناشناسی استفاده کنید. ( I943ff )
  • API requestAutofill طوری بازنویسی کنید که خارج از مدیریت تکمیل خودکار وجود داشته باشد. ( Id1929 )

رفع اشکالات

  • مشکل فوکوس که در آن requestFocus() با پارامتر بی‌معنی previouslyFocusedRect (مربوط به جهت فوکوس) از ComposeView عبور می‌کرد، برطرف شد. ( Ifdc2f , b/388590015 )
  • مشکل NPE گاه به گاه هنگام استفاده از GraphicsLayer.record { this@ContentDrawScope.drawContent() } برطرف شد. اگر drawContent() به این روش ضبط می‌کنید، مطمئن شوید که از تابع افزونه GraphicsLayer#record درون DrawScope استفاده می‌کنید و نه از تابع عضو روی GraphicsLayer . ( I75fc0 , b/389046242 )
  • رفع مشکل طرح‌بندی متن با حذفی که گاهی اوقات در طول انیمیشن‌ها به اشتباه ترجمه می‌شد، برای اطلاعات بیشتر به b/389707025 مراجعه کنید ( Ie55b1 ، b/389707025 )

نسخه ۱.۸.۰-آلفا۰۸

  • چندین مشکل مربوط به فوکوس برطرف شد، از جمله خرابی‌هایی که هنگام تلاش IME برای فوکوس روی ComposeView بدون آیتم‌های قابل فوکوس، تغییر فوکوس در AndroidViews فرزند و درخواست فوکوس هنگام خروج از AndroidView رخ می‌داد. ( Ia03c3 ، b/369256395 ، b/378570682 ، b/376142752 )
  • تغییر FocusEnterExitScope.cancelFocus() به cancelFocusChange() ( I89959 )
  • اکنون می‌توانید انسدادهای ترکیبی (Composable occlusions) را با RectInfo.calculateOcclusions() محاسبه کنید.
  • Added extension function on DelegatableNode to register a listener for global layout changes. ( I68b59 )

رفع اشکالات

  • اکتیویتی‌ای که هنگام استفاده از ComposeContentTestRule.setContent به عنوان میزبان برای composable تحت تست استفاده می‌شود، اکنون از تم Theme.Material.Light.NoActionBar استفاده می‌کند تا از همپوشانی ActionBar با محتوای تست هنگام هدف قرار دادن SDK 35 جلوگیری شود. برای جلوگیری از این رفتار، می‌توانید وابستگی به ui-test-manifest حذف کرده و یک ورودی اکتیویتی در AndroidManifest.xml برنامه تست خود برای ComponentActivity با تم دلخواه خود اضافه کنید. ( I7ae1b ، b/383368165 )
  • Resource fonts with the same variation settings will now avoid over-caching causing the incorrect variation settings to be applied. ( If3dff , b/372044241 )
  • AnnotatedString.fromHtml now supports <ul>/<li> tags. ( I7c2fe , b/299662276 , b/139326648 )

  • Fixed missing backgrounds with long screenshots. ( I4d57a )
  • This library now uses JSpecify nullness annotations , which are type-use. Kotlin developers should use the following compiler argument to enforce correct usage: -Xjspecify-annotations=strict (this is the default starting with version 2.1.0 of the Kotlin compiler). ( Idfef8 , b/326456246 )
  • Update Compose support for wide gamut and HDR colors when running on Android Q+. ( Icd8be , b/379135036 )
  • Resource fonts that fail to load will now silently fall back to the default font, instead of the prior behavior of throwing an exception in measure. ( Ib6a49 )
  • Fix focus lost when AndroidView is detached and attached. ( I53446 )
  • Accept requestFocus() from beyond bound layout action. ( Ia8461 )

مشارکت خارجی

  • Add BringIntoViewResponderModifierNode to UI, which provides a new way to implement Bring Into View functionality as well as allows implementing in on a platform level. ( Ia6dd8 )

نسخه ۱.۸.۰-alpha06

  • Adding autofill support in text toolbar. ( Ie6a4c )
  • API changes to Modifier.focusRestorer() ( I99c03 ):
    • parameter name changed to 'fallback'
    • parameter is now a FocusRequester and not a lambda
    • parameter is now non-NULL with Default as the default value
  • Removing @Experimental annotation from autofill manager interface. The feature is still WIP targeting this release but we do not want to introduce @Expemiental API ( Id8398 )
  • LocalHapticFeedback now provides a default HapticFeedback implementation when the Vibrator API indicates that haptics are supported. The following have been added to the HapticFeedbackType - Confirm , ContextClick , GestureEnd , GestureThresholdActivate , Reject , SegmentFrequentTick , SegmentTick , ToggleOn , ToggleOff , VirtualKey . Wear Compose long-clickable components such as Button , IconButton , TextButton , and Card now perform the LONG_PRESS haptic when a long-click handler has been supplied. ( I5083d )
  • Removes OverscrollConfiguration and LocalOverscrollConfiguration , and adds rememberPlatformOverscrollFactory to create an instance of / customize parameters of the default overscroll implementation. To disable overscroll, instead of LocalOverscrollConfiguration provides null , use LocalOverscrollFactory provides null . To change the glow color / padding, instead of LocalOverscrollConfiguration provides OverscrollConfiguration(myColor, myPadding) , use LocalOverscrollFactory provides rememberPlatformOverscrollFactory(myColor, myPadding) . ( Ie71f9 , b/255554340 , b/234451516 )
  • Removed the experimental GlobalAssertions API. It's intended use was to run accessibility checks, see enableAccessibilityChecks() for that purpose instead. ( I59322 )

نسخه ۱.۸.۰-آلفا۰۵

۳۰ اکتبر ۲۰۲۴

androidx.compose.ui:ui-*:1.8.0-alpha05 is released. Version 1.8.0-alpha05 contains these commits .

ویژگی‌های جدید

Autofill is exposed behind a feature flag in this release. We are working on improving performance, and are looking for early feedback on the APIs. The APIs are expected to evolve prior to stable based on feedback.

  • To enable Autofill, set ComposeUiFlags.isSemanticAutofillEnabled to true in onCreate and use the latest Compose Snapshot.
  • This version of Autofill supports saving credentials manually, through Suggest Strong Password, and through navigation. It also supports filling when an autofillable field receives focus or when Autofill is triggered via the text toolbar on text components. The component will become highlighted to indicate when autofill has completed.

تغییرات API

  • Modify Autofill interface to follow expect / actual structure. ( I22dce )
  • Introduce CompositionLocal that can be used to modify the hue of Autofill's successful filling highlight. ( I32092 )
  • Added Modifier.onRectChanged API which is an API that allows one to subscribe to the root/window/screen-relative position and size of a LayoutNode . The API solves many use cases that the existing onGloballyPositioned modifier does, however it does so with much less overhead and the API comes with facilities to debounce and throttle the callback per what one's use case demands. ( Id28c7 , b/372765423 , b/372757007 , b/372994338 )
  • Expands Autofill manager to include commit() and cancel() APIs that help users save newly entered credentials. ( I2da00 )
  • Introduces new AutofillManager interface that can be used to fine-tune users' Autofill journey and a isSemanticAutofillEnabled flag to turn on this new version of Autofill. ( I9d484 )
  • Added Modifier.onRectChanged API which is an API that allows one to subscribe to the root/window/screen-relative position and size of a LayoutNode . The API solves many use cases that the existing onGloballyPositioned modifier does, however it does so with much less overhead and the API comes with facilities to debounce and throttle the callback per what one's use case demands. ( I3c8fa )

نسخه ۱.۸.۰-آلفا۰۴

۱۶ اکتبر ۲۰۲۴

androidx.compose.ui:ui-*:1.8.0-alpha04 is released. Version 1.8.0-alpha04 contains these commits .

تغییرات API

  • Adds DelegatableNode#onDensityChange and DelegatableNode#onLayoutDirectionChange callbacks to allow updating node state when these change ( I04f3e , b/340662451 )
  • Adds WindowInfo#containerSize to provide the current window's content container size. This can be retrieved using LocalWindowInfo . ( Idc38c , b/369334429 , b/360343819 )
  • Introduce a fix for nested scrollables that are removed from the node tree during an ongoing fling. Now these nodes will cancel the fling and correctly send the onPostFling event with the remaining velocity. We're also introducing the flag NewNestedScrollFlingDispatchingEnabled to control the behavior in case of regressions. The flag will be removed before beta. ( I05c37 , b/371168883 )
  • Introduced PointerInputModifierNode#touchBoundsExpansion , which can be used to enlarge the touch bounds of a single pointer input modifier. ( Iccf02 , b/335339283 )
  • Adds WindowInfo#containerSize to provide the current window's content container size. This can be retrieved using LocalWindowInfo . ( I27767 , b/369334429 , b/360343819 )
  • برای پین کردن به نسخه پایه پایدار، readOnly از TextFields حذف کنید. ( I3aaba )
  • Paragraph and ParagraphIntrinsics now takes a list of all annotations applied to the AnnotatedString , previously it only had a list of SpanStyles ( I12f80 )

رفع اشکالات

  • Updated how paragraphs are treated in AnnotatedString . Before you could only create non-overlapping paragraphs. Now the AnnotatedString allows fully-overlapping paragraphs which will be merged together, and nested paragraphs in which case the outer paragraph will be split on bounds of the inner one, and the inner paragraph's style will be merged with the outer paragraph's style ( Ic9554 )
  • Fix crash in AnnotatedString with a zero-length LinkAnnotation . ( 89aac6 )

  • Fixed an issue where placement happened on detached nodes in LazyList by separating the management of subcomposition for different layout passes.
  • Fixed a problem where the Software Keyboard flickers when focus switches from a TextField to an EditText or any other View based editor.
  • Nested Scroll nodes will now dispatch onPostFling events correctly after they get detached.
  • General performance improvements

۲۹ مه ۲۰۲۴

androidx.compose.ui:ui-*:1.7.0-beta02 is released. Version 1.7.0-beta02 contains these commits .

تغییرات API

  • Renamed SemanticsProperties.Editable to IsEditable and changes SemanticsPropertyReceiver.editable to a val isEditable . The property is now a boolean and always specified by text fields. ( I8acd8 )
  • Rename accessibility benchmark parameter. ( I3d440 )
  • Updated API for styling the links: TextLinkStyles is now part of the LinkAnnotation constructor and the AnnotatedString.fromHtml method ( I90b2b ). Also removed the TextDefaults from material ( I5477b )

رفع اشکالات

  • Renamed LayoutCoordinates.introducesFrameOfReference to LayoutCoordinates.introducesMotionFrameOfReference to better reflect its purpose. Renamed related function to calculate coordinates based on that flag. ( I3a330 )

رفع اشکالات

  • Fixes additional use cases when dynamically adding pointer input modifiers during events 63e1504

نسخه ۱.۷.۰-آلفا۰۸

۱ مه ۲۰۲۴

androidx.compose.ui:ui-*:1.7.0-alpha08 is released. Version 1.7.0-alpha08 contains these commits .

تغییرات API

  • Adds support for mutable shape implementations. Shape#createOutline is now observed inside graphics layers, so reading state values inside will cause invalidations when the state changes, allowing for more performant shape animations. ( Id1629 , b/326070216 )
  • Renamed isPositionedByParentWithDirectManipulation to introducesFrameOfReference . Note that it now has the reverse effect, meaning that by default, most LayoutCoordinates introduce a frame of reference, and, only when placed under direct manipulation the property will be false. To query position with only those that introduce a frame of reference, use positionInLocalFrameOfReference(...) . Or positionInLocalLookaheadFrameOfReference from a LookaheadScope . ( Ifc5f7 )
  • LookaheadScope APIs have been made stable ( I21507 )
  • Change action lambda for getScrollViewportLength as per API council feedback. ( Ibc74a )
  • Updated GraphicsLayer outline APIs to consume float parameters instead of int. Removed UnsetOffset/UnsetSize IntSize sentinel values in favor of already existing Unspecified constants on float based Offset and Size inline classes ( I2fb03 , b/333863462 )
  • When injecting mouse input during tests, MouseInjectionScope.click() , MouseInjectionScope.doubleClick() , MouseInjectionScope.tripleClick() , MouseInjectionScope.longClick() now accept a button: MouseButton parameter to make them more universally applicable. The default value is MouseButton.Primary for all methods. ( I31a23 , b/190493367 , b/261439695 )
  • Renamed onClicked to onClick inside LinkInteractionListener . ( Iaa35c )
  • Rename TextInclusionStrategy.isInside to isIncluded . Make Paragraph/MultiParagraph#getRangeForRect() return type non nullable. ( I51f26 )

رفع اشکالات

  • Fixed long screenshot capture for scrolling containers with reverseScrolling=true . ( I7c59c )

مشارکت خارجی

  • Added support for prefetching items in nested LazyLists (eg a LazyColumn that renders nested LazyRows ). This change is expected to reduce frame drops during scrolling for these LazyLists . The implementation default is to prefetch the first 2 nested items, however this behavior can be controlled by the new LazyLayoutPrefetchStrategy(nestedPrefetchItemCount) and LazyListPrefetchStrategy#onNestedPrefetch APIs. ( I51952 )

نسخه ۱.۷.۰-آلفا۰۷

۱۷ آوریل ۲۰۲۴

androidx.compose.ui:ui-*:1.7.0-alpha07 is released. Version 1.7.0-alpha07 contains these commits .

تغییرات API

  • ClickableText is marked as deprecated. To add links to the text, create an AnnotatedString with a LinkAnnotation corresponding to your link and pass this AnnotatedString to the Text composable. ( I34d4b , b/323346994 )
  • Introduce ViewConfiguration.HandwritingGestureLineMargin for handwriting gestures. Support JoinOrSplit gesture for BasicTextField ( Ie6e13 , b/325660505 )
  • FocusProperties.enter and FocusProperties.exit are no longer experimental. FocusDirection.Enter and FocusDirection.Exit are no longer experimental. FocusRequester.Cancel is no longer experimental ( I461a1 , b/261564106 )
  • When querying Layout coordinates, you may now use the excludeDirectManipulationOffset argument to exclude the offset set by parent Layouts that placed their children using Placeable.PlacementScope.withDirectManipulationPlacement . Likewise, a Layout that changes the position of its children frequently may now place them using withDirectManipulationPlacement (such as Scroll, implemented by default). This helps approachLayout based animations to be more intuitive, having now the opportunity to differentiate what offset to animate, and what to apply directly when deciding to animate their approach. ( I60ec7 )
  • The feature flag for long screenshots has been removed. ( I28648 , b/329128246 )
  • LazyColumn will now render sticky headers correctly in long screenshots. ( I8d239 , b/329296635 )
  • NestedScroll sources Drag and Fling are being replaced by UserInput and SideEffect to accommodate for the extended definition of these sources that now include animations (Side Effect) and Mouse Wheel and Keyboard ( UserInput ). ( I40579 )
  • ApproachLayoutModifierNode and Modifier.approachLayout are now stable, with new isMeasurementApproachInProgress() and isPlacementApproachInProgress() to replace the old isMeasurementApproachComplete() and isPlacementApproachComplete() respectively.
  • Removed deprecated intermediateLayout modifier. ( I3e91c )
  • Rename GraphicsLayer#buildLayer to record to mirror the begin/endRecording methods of Displaylist backed APIs like RenderNode and Picture.
  • Updated rememberGraphicsLayer to leverage rememberObserver . ( I312c1 , b/288494724 , b/330758155 )
  • UrlAnnotation is deprecated, use LinkAnnotation.Url instead. If you're using Material theming, then use TextDefaults object to create the annotation with Material theming applied to it ( I8d180 , b/323346545 )
  • Text links got pressed state styling option in addition to normal styling, hovered and focused ( I5f864 , b/139312671 )
  • String.parseAsHtml renamed to AnnotatedString.Companion.fromHtml . ( I43dcd )
  • Added styling arguments ( linkStyle , focusedLinkStyle , hoveredLinkStyle ) and a link interaction listener to the parseAsHtml method. When parsing the HTML-tagged string with <a> tags, the method will construct a LinkAnnotation.Url for each such tag and pass the styling objects and link interaction listener to each annotation. ( I7c977 )
  • LinkAnnotation now takes the state-based styling arguments and a LinkInteractionListener . Add this annotation to the AnnotatedString to get a hyperlink. By passing focusedState and/or hoveredState you can define the visual configuration for links when they are focused and/or hovered. ( I81ce4 , b/139312671 )
  • ImeOptions.hintLocales is no longer nullable. If you want to pass an empty Locale list, please use LocaleList.Empty . ( Ic5bc4 )

رفع اشکالات

  • Gracefully handles bad/corrupt historical input event data (ignores bad offset data).
  • Fixes unexpected pointer events when a pointer input modifier is added dynamically before another pointer input modifier during an active pointer input event stream (for example, between a hover enter and hover exit [mouse/stylus]).

نسخه ۱.۷.۰-alpha06

۳ آوریل ۲۰۲۴

androidx.compose.ui:ui-*:1.7.0-alpha06 is released. Version 1.7.0-alpha06 contains these commits .

ویژگی‌های جدید

  • Added parseAsHtml method for styled strings: it allows to convert a string marked with HTML tags into AnnotatedString . Note that not all tags are supported, for example you won't be able to display bullet lists yet. ( I84d3d , I30626 , b/139326648 )
  • Implemented experimental support for long screenshots in Compose scroll containers using the official Android API ( ScrollCaptureCallback ). This feature is experimental and may not currently handle all cases correctly. For that reason it is currently disabled by default. To opt-in, set the ComposeFeatureFlag_LongScreenshotsEnabled flag to true. ( I2b055 , b/329296471 )

تغییرات API

  • fun ClipEntry.getMetadata() is changed to val ClipEntry.clipMetadata . ( I50155 )
  • Removed ClipboardManager.getClipMetadata and ClipboardManager.hasClip functions. Please use clipEntry.getMetadata() to read the current clip entry's metadata. Also check ClipboardManager.getClip 's result if it's null or not to understand whether Clipboard has a current clip. ( I50498 )
  • Now you can pass GraphicsLayer objects into placeable.placeWithLayer() functions ( I1b22f )
  • ClipboardManager.setClip now accepts null to be able to clear the Clipboard. ( I7d2e9 )
  • Added resource ids for assist with hiding Views used as implementation details within build tooling ( I99531 )
  • Added GraphicsLayer#toImageBitmap suspend method to support rendering contents of a bitmap into a GraphicsLayer . This is a hardware accelerated rendering operation on API level 22+ (inclusive) which supports over 99% of all Android devices. On Android API level 21 this falls back onto software rendering. ( I9e114 )
  • Helper method to convert an Android RectF to ComposeRect ( I39925 , b/325660505 )
  • All KeyboardOptions parameters now have an unspecified value by default. Added KeyboardOptions.merge method.
  • Renamed KeyboardOptions.autoCorrect to autoCorrectEnabled and made it nullable, where null indicates no value was specified. ( Ia8ba0 , b/295951492 )
  • BasicTextField(state) variant and BasicSecureTextField now use KeyboardActionHandler instead of KeyboardActions to process actions taken by the software keyboard. ( I58dda )

نسخه ۱.۷.۰-آلفا۰۵

۲۰ مارس ۲۰۲۴

androidx.compose.ui:ui-*:1.7.0-alpha05 is released. Version 1.7.0-alpha05 contains these commits .

ویژگی‌های جدید

  • Introduce new GraphicsLayer API to record drawing commands in a display list as well as additional properties that affect the rendering of the display list. This provides an isolation boundary to divide a complex scene into smaller pieces that can be updated individually of one another without recreating the entire scene. Transformations made to a GraphicsLayer can be done without re-recording the display list. Unlike Modifier.graphicsLayer , GraphicsLayer allows for rendering of Composable content elsewhere and is useful in animated use cases where content is expected to be rendered in different scenes.

تغییرات API

  • GraphicsLayer.draw(Canvas) is not a public api anymore. Please use the DrawScope.drawLayer(GraphicsLayer) extension function instead to draw the layer. ( I7a7c0 )
  • Split restrictedConstraints() to two methods: fitPrioritizingWidth() and fitPrioritizingHeight() ( I6d7fd )
  • Introduced HardwareCanvas stub for Android L usage ( I1c3b5 , b/288494724 )
  • Update Compose framework to expose a GraphicsContext composition local alongside updating Owner, DelegateableNode and drawWithCache Modifier implementations to expose access to the GraphicsContext for scoped access that will automatically cleanup GraphicsLayer instances when Modifiers are torn down. ( I64a2f , b/288494724 )
  • Introduced InterceptPlatformTextInput for helping write low-level IME-related tests and other low-level IME use cases. PlatformTextInputTestOverride has been deprecated. ( I862ed , b/322680547 )
  • GraphicsLayer.setOutline(Outline) extension function was added. ( Ib81f4 )
  • Introduce GraphicsContext function constructor to create a factory to create GraphicsLayer instances ( Ib98d6 , b/288494724 )
  • Exposed GraphicsLayer API to provide developer defined flexibility in capturing drawing commands that can be used to draw elsewhere and also apply different visual effects to the end result. ( I80245 , b/288494724 )
  • Introduce the Paragraph#getRangeForRect which returns a range of text covered by a given rectangle area. ( Iee516 , b/325660505 )
  • Removed experimental override of BasicText with onLinkClicked argument. A replacement API for hyperlinks support will follow in the future. ( I107d5 )

رفع اشکالات

  • Added GraphicsLayer expect/actual API definition to support capturing and replaying of drawing commands with optional compositing visual effects and transforms. Introduce GraphicsContext interface to contain graphics dependencies including creation and management of GraphicsLayer instances. ( I4a8d6 , b/288494724 )
  • Fixed an interop issue with 1D focus search where focus would get stuck inside a ComposeView that was embedded among other views. ( I08fd4 )

مشارکت خارجی

  • LocalLifecycleOwner moved from Compose UI to lifecycle-runtime-compose so that its Compose-based helper APIs can be used outside of Compose UI. Thanks Jake Wharton for the contribution. ( I6c41b , b/328263448 )
  • Consistently expose bias float properties on all bias-based alignment subtypes. ( I69f0f , b/328088992 )

نسخه ۱.۷.۰-آلفا۰۴

androidx.compose.ui:ui-*:1.7.0-alpha04 is released. Version 1.7.0-alpha04 contains these commits .

تغییرات API

  • Support stylus handwriting feature for BasicTextField2 on devices after Android U. ( I002e4 )
  • In this CL we are adding the GetScrollViewportLength semantic action so we can pipe up information about the components being scrolled in compose to the a11y system. This CL also applies the usage of said property in Foundation Scrollable Lists. ( Ic5fa2 )
  • FocusRequester.createRefs is now stable ( I4d92c , b/261436820 )
  • Introduced DelegatableNode.requireView() to allow modifier nodes to get the current Android View without reading a composition local. ( I40768 )
  • New API Path.reverse() to reverse a path's direction ( I36348 )
  • Added hintLocales to KeyboardOptions to provide TextFields with the ability to hint IMEs with specific locales to preset a preferred language.
  • Expose platformLocale property from Locale that returns the underlying platform object, eg java.util.Locale . ( I921c6 )

نسخه ۱.۷.۰-آلفا۰۳

۲۱ فوریه ۲۰۲۴

androidx.compose.ui:ui-*:1.7.0-alpha03 is released. Version 1.7.0-alpha03 contains these commits.

تغییرات API

  • Introducing ContextualFlowRow and Enhanced FlowRow / Column with MaxLines and Overflow. We are excited to announce enhancements to the experimental FlowRow and FlowColumn , now featuring maxLines and overflow support, alongside the debut of ContextualFlowRow and ContextualFlowColumn . This update is designed to provide performance optimal components, where ContextualFlow* is perfect for a large number of items making use of a small maxLines config and dynamic +N see more buttons, and FlowRow and FlowColumn is perfect for a small number of items, less than 100 items. Important: To maintain existing behavior in FlowRow or FlowColumn where all items are composed regardless of if they fit the cross axis max, set overflow to FlowRowOverflow.Visible or FlowColumnOverflow.Visible during initialization. Explore ContextualFlowRowSample and FlowRowSample for examples of these new features in action. ( Ib9135 , b/293577082 )
  • Add maxTextLength semantics property that should be set on text fields that filter the maximum allowed number of characters. ( I24d9f , b/170648072 )
  • The Modifier.inspectable wrapper has been deprecated. This API will create more invalidations of your modifier than necessary, so its use is now discouraged. Developers are encouraged to implement the inspectableProperties() method on ModifierNodeElement if they would like to expose modifier properties to tooling. ( Ib3236 )
  • New constructor for PopupProperties which allows for full control over WindowManager.LayoutParams flags. ( Ibb33e , b/312485503 )
  • Introduced DelegatableNode.requireLayoutCoordinates() as a way to get a Modifier.Node 's current LayoutCoordinates without needing to override onPlaced and store the coordinates in a property yourself. ( Ia8657 )
  • Introduced DelegatableNode.currentLayoutCoordinates as a way to get a Modifier.Node 's current LayoutCoordinates without needing to override onPlaced and store the coordinates in a property yourself. ( Iaebaa )
  • BasicTextField2 and related APIs under androidx.compose.foundation.text2 package are moved to androidx.compose.foundation.text . ( I9f635 )
  • Added a new ApproachLayoutModifierNode API to support creating custom approach logic in an explicit Modifier Node. Also added a new experimental DeferredTargetAnimation API for animations whose target is unknown at instantiation. ( I60745 )
  • New Path APIs to query the direction of a Path and to extract contours from a Path . ( I63d04 )
  • Added PathHitTest and Path.contains(Offset) to check if a Path contains a specific point. ( I3b218 )
  • The TextLayoutResult now exposes the getLineBaseline(lineIndex) method. This allows to read the baseline of an arbitrary line of the text in addition to existing convenience properties firstBaseline and lastBaseline . ( Ide4e8 , b/237428541 )
  • Added method to compare only the annotations of two AnnotatedStrings . ( I32659 )

  • Updated maximumFlingVelocity to be represented as Float. Updated documentation to be more clear about the maximumFlingVelocity unity. ( I8adc7 )
  • onDragAndDropStart in the DragAndDropModifierNode factory has been renamed to acceptDragAndDropTransfer . acceptsDragAndDropTransfer has been added to the dragAndDropTarget Modifier to accept from a drag and drop session. This lambda returns a viable DragAndDropTarget if interested in a drag and drop session. Other lambdas for processing drag events have been replaced by this. a DragAndDropTarget factory function has been added to receive from drag and drop sessions ( Iebf3a )

  • Removed DragAndDropInfo as a type DragAndDropModifierNode.drag now takes parameters for the transferData , decoration size and drag decoration DrawScope lambda

    DragAndDropTarget has methods for particular drag and drop events instead of being a single abstract method

    onDragAndDropEvent in the factory function for a DragAndDropModifierNode has been renamed to onDragAndDropStart to better communicate that the DragAndDropTarget provided is valid for a given drag and drop session only

    The DragAndDropEventType has been removed ( I645b1 )

New assertIsDeactivated() test API was introduced to test such nodes. The rests of the test apis will filter out deactivated nodes by default. ( I2ef84 , b/187188981 )

  • Removed FocusDirection.In and FocusDirection.Out use FocusDirection.Enter and FocusDirection.Exit instead ( I2f660 )

  • Material SwipeToReveal APIs (for Cards and Chips) now rely on a slot based API (as recommended by Compose) instead of data class based instances to create those slots. This is a breaking change, please see the demo and sample code for examples on how to use the new API. ( Ia8943 )

  • Add showSystemUi=true to PreviewScreenSizes definition ( Ib61d3 )

تغییرات رفتاری

  • Compose now uses non-linear font scaling for better readability and accessibility. When font scale > 100% in system settings, small text will increase in size normally, but already-large text will only increase a little bit. Also, line heights defined in SP will automatically adjust to stay proportional to the 100% scale intended height. See the Font Scaling Best Practices for more info. ( I11518 )

نسخه ۱.۶.۰-آلفا۰۲

۲۶ ژوئیه ۲۰۲۳

androidx.compose.ui:ui-*:1.6.0-alpha02 is released. Version 1.6.0-alpha02 contains these commits.

تغییرات API

  • Added a service locator interface that can be implemented by implementors of Composition that allows an implementation of Composition that delegates to another composition delegate service lookups to the original Composition. This should not be called directy and is used to enable creating experimental APIs in the runtime that can be found from wrapped versions of the composer such as the UI module does. ( I296b9 )
  • Completely redesigned PlatformTextInput* API. ( I6c93a , b/274661182 , b/267235947 , b/277380808 )

This fixes a bug where the update callback wouldn't be invalidated if a state it read was changed immediately by an effect. ( Ie9438 , b/291094055 )

نسخه ۱.۶.۰-آلفا۰۱

۲۱ ژوئن ۲۰۲۳

androidx.compose.ui:ui-*:1.6.0-alpha01 is released. Version 1.6.0-alpha01 contains these commits.

ویژگی‌های جدید

  • Support lookahead in LazyList . This allows LazyList in the lookahead pass to bypass any animation (eg item placement animation, AnimatedVisibility , etc) and to calculate the lookahead size and position for all children. After the lookahead pass, children of LazyList could animate independently to the reality as seen in the lookahead pass.

Behavior Change: includeFontPadding is now false by default in Compose

includeFontPadding is now false by default ( 21d806 ) in Compose.

includeFontPadding is a legacy attribute that controls whether or not to include extra padding on top of the first line and last line of the text to accommodate any characters that may extend above or below the text baselines.

Updating this Compose version will modify how all texts render in your UI by removing the extra padding on top of the first line and last line of every text you display.

Depending on your UI requirements and the font metrics you're using, the changes should be minimal. However you might encounter blockers such as: - Broken screenshot tests. Fix the UI if required, and regenerate the golden images. - Text is slightly misaligned. Remove any custom negative paddings or add padding if required.

You can opt-in to includeFontPadding by using PlatformTextStyle for each text:

Text(
 text = myText,
 style = TextStyle(
   lineHeight = 2.5.em,
   platformStyle = PlatformTextStyle(
     includeFontPadding = true/false
   )
   /* … */
  )
)

You can opt-in to includeFontPadding for all your texts by configuring your Material styles. Note that parameter names will vary between M2 and M3.

val Typography = Typography(
   body1 = TextStyle(
       fontFamily =    /* … */,
       fontSize =    /* … */,
       platformStyle = PlatformTextStyle(
           includeFontPadding = false
       )
   /* … */
   )
)

MaterialTheme(
   typography = Typography,
   /* … */
)

You can find more about Compose includeFontPadding in developer documentation and this blog post .

ویژگی‌های جدید

  • New default behavior for SubcomposeLayout in LookaheadScope : SubcomposeLayouts that don't have conditional slots (eg TabRow , Scaffold , BoxWithConstraints , etc) now work nicely with lookahead animations.

تغییرات API

  • New default intermediateMeasurePolicy that reuses measure policy from lookahead pass allows SubcomposeLayout subtypes without conditional slots such as Scaffold , TabRow , and BoxWithConstraints to work with lookahead by default. ( Id84c8 )
  • The recomposer created for an Android window will now only block calls to withFrameNanos instead of all composition when it receives an ON_STOP notification. This means windows associated with stopped activites will continue to recompose for data changes but the animations, or any other caller of withFrameNanos , will block. ( Id9e7f , b/240975572 )
  • Changes motionEventSpy to stable. ( Ic5ec4 , b/261560988 )
  • Added public TextRange.constrain method. ( I97912 )
  • PlatformTextStyle.includeFontPadding is no longer deprecated to encourage developers to use this compatibility API to switch and test setting includeFontPadding false. ( I98e96 , b/277703184 )

نسخه ۱.۵.۰-آلفا۰۲

۵ آوریل ۲۰۲۳

androidx.compose.ui:ui-*:1.5.0-alpha02 is released. Version 1.5.0-alpha02 contains these commits.

تغییرات API

  • New SubcomposeLayout API that takes an additional intermediate measure policy for handling measure/layout logic during lookahead-based animations. ( I017d3 )
  • PointerInput is now lazy and uses Modifier.Node for better performance ( read about the minor behavior change ). ( 15dab9 )
  • Changes experimental APIs to stable with Key events. ( I9c7d8 , b/261566839 , b/261567368 )
  • Changes experimental APIs to stable in PointerInputChange . ( I1b543 , b/261560988 , b/261565762 , b/261565749 )
  • Adds a way to instantiate a SuspendingPointerInputModifierNode for more complex Modifier.Node implementations. ( Ic4933 )
  • UrlAnnotation s in AnnotatedString s can now be opened via accessibility services like TalkBack . ( If4d82 , b/253292081 )
  • Added an API to intercept hardware keys before they are sent to the soft keyboard ( I4f4c6 , b/186800395 )
  • Added the InsertTextAtCursor semantics action for text fields. ( I11ed5 )
  • Text-related test actions (eg performTextInput ) will now request focus directly, using the semantics action, instead of clicking on the field. ( I6ed05 )

رفع اشکالات

  • Text test actions now require text fields to be enabled. ( Iab328 )

نسخه ۱.۵.۰-آلفا۰۱

۲۲ مارس ۲۰۲۳

androidx.compose.ui:ui-*:1.5.0-alpha01 is released. Version 1.5.0-alpha01 contains these commits.

تغییرات API

  • Modifier.intermediateLayout now doesn't require an explicit LookaheadScope. The measure block in intermediateLayout has IntermediateMeasureScope as receiver, which provides convenient CoroutineScope, LookaheadScope and MeasureScope.( Ibe2e5 )
  • LookaheadLayout has been replaced by LookaheadScope, which is no longer a Layout. This allows chid content in a LookaheadScope to be directly controlled by parent's MeasurePolicy. ( Ibe2e5 )
  • Adds Modifier.Node#coroutineScope to allow Modifier.Nodes to launch coroutines. ( I76ef9 )
  • Allow Modifier.Nodes to read CompositionLocals by implementing the CompositionLocalConsumerModifierNode interface. ( Ib44df )
  • Propagation of @Deprecated class to property. ( I882d1 )

تغییرات مهم از زمان ۱.۳.۰

  • Added a new PinnableContainer API that allows lazy list items to be pinned, so that they are not disposed when they are scrolled out of bounds. For example, Modifier.focusable() uses this mechanism to pin the currently focused item. ( Ib8881 , b/259274257 , b/195049010 )
  • The focus system is rewritten using the new experimental Modifier.Node APIs. ( I7f4d7 , b/247708726 , b/255352203 , b/253043481 , b/247716483 , b/254529934 , b/251840112 , b/251859987 , b/257141589 )
  • Added in IsContainer semantics property on Surfaces. This property will be used in a later change that determines traversal order based on the semantic meaning of elements such as surfaces. ( I63379 )
  • Added a new accessibility role DropdownList . This can be used to replicate TalkBack 's behavior when focusing android.widget.Spinner . ( I177e5 , b/236159001 )
  • You can now use PlatformTextStyle(emojiSupportMatch) to optionally disable emoji support processing for a single Paragraph. ( Ia7100 , b/139326806 )
  • Android Compose UI tests will now run layout passes for each frame when executing frames to get to idle (eg via waitForIdle ). This may affect tests that assert on individual frames of layout animations. ( I8ea08 , b/222093277 )
  • Added experimental TextMotion to TextStyle to define Text either to be Static(default) or Animated. Use TextMotion.Animated if Text is going to be scaled, translated, or rotated via animation. ( I24dd7 )

androidx.compose.ui:ui-*:1.4.0-rc01 is released. Version 1.4.0-rc01 contains these commits.

تغییرات API

  • Added an overload of AndroidView composable function, which accepts the onReset param. It allows View instances to be reused when their node in the composition is discarded and reused in a compatible way. This is especially useful for LazyRows and LazyColumns of Views. ( I3f10d , b/230099236 )
  • Introduced new low-level PlatformTextInputAdapter API for building custom text input implementations that talk directly to platform APIs. ( I58df4 )

رفع اشکالات

  • BasicTextField 's SetText semantics action will now update the text buffer using the same code path as IME updates and the testing functions (eg performTextReplacement ).
  • Text testing functions performTextClearance , performTextReplacement , and performTextSelection now use SemanticsActions . ( I0807d , b/269633168 , b/269624358 )

نسخه ۱.۴.۰-بتا۰۲

۲۲ فوریه ۲۰۲۳

androidx.compose.ui:ui-*:1.4.0-beta02 is released. Version 1.4.0-beta02 contains these commits.

تغییرات API

  • Removed the modifierElementOf() API. Please extend from ModifierNodeElement directly instead. ( I2256b )
  • Added a new Modifier.Node.onReset() callback allowing you to reset some local state to properly handle the case when the Layout will be reused (for example as an item of LazyColumn ). Fixed FocusTargetModifierNode to properly reset the focused state. ( I65495 , b/265201972 )
  • Added BlendMode parameter to DrawScope.drawText , Paragraph.paint , and MultiParagraph.paint methods to support different blending algorithms when drawing text on Canvas. ( I57508 )

  • PinnableContainer.PinnedHandle.unpin() was renamed to release() ( I4667a )
  • Added waitUntilNodeCount , waitUntilAtLeastOneExists , waitUntilExactlyOneExists and waitUntilDoesNotExist as experimental API to ComposeTestRule , extending the waitUntil API to accept any matcher and any count of nodes. See ComposeTestRule for further documentation. ( Ifa1b9 , b/226934294 )
  • Rename Font.MaximumAsyncTimeout to Font.MaximumAsyncTimeoutMillis . ( I07af5 )
  • Removed GoogleFont.Provider.AllFontsListUri and linked to it in ktdoc instead. ( I16f29 )

تغییرات API

  • Replaced maxSize: IntSize argument in drawText with size: Size to be inline with other DrawScope functions. size is set to Size.Unspecified by default which should not change the previous default behavior. ( Icd27d )
  • Removed deprecated experimental font constructor. ( I8a724 , b/261435386 )
  • The ui tooling data class Group now has a field, isInline , that indicates if the group is for a call to an inline composable function. If isInline is true then the call is to an inline composable function. However, the value might be false for calls to inline composable functions that are from modules that are compiled with a version of the compose compiler plugin that doesn't generate the inline function information. ( Idb846 )
  • Graduated a number of previously experimental APIs to stable
  • Rotary Scroll Event API is now stable ( I42ad3 , b/261561229 )

Version 1.4.0-alpha03

۷ دسامبر ۲۰۲۲

androidx.compose.ui:ui-*:1.4.0-alpha03 is released. Version 1.4.0-alpha03 contains these commits.

تغییرات API

  • Removing ExperimentalComposeUiApi from PointerIcon ( I23af8 )
  • Introduce Page accessibility actions: PageUp , PageDown , PageLeft , PageRight . Note that these are only available from API 29. ( Ida4ab )
  • Updated rememberNestedScrollConnection parameter view from root view to host view. ( Ia5200 )
  • Added an Modifier API to query ancestors scroll info. ( I2ba9d , b/203141462 )
  • Used in Clickable to correctly delay press interactions, when gestures could become scroll events.
  • Fixed Clickables not correctly delaying ripples, when used inside an Scrollable ViewGroup .
  • کشوها و برگه‌ها به‌روزرسانی شدند تا در صورت تبدیل شدن حرکات به رویدادهای پیمایش، فشارها را به درستی به تأخیر بیندازند.
  • Renamed CompositingStrategy.Always to Offscreen to indicate that the graphicsLayer will always be rendered into an intermediate buffer ( I47dc1 )
  • Layout overload with multiple content slots is now stable ( I10566 , b/248294649 )
  • Added experimental new APIs PerfettoTrace.record {} and PerfettoTraceRule to capture Perfetto traces (also known as System Traces) as part of a test, to inspect test behavior and performance. ( I3ba16 )
  • In UI tests using a Compose rule, continuations resumed during withFrameNanos callbacks will not be dispatched until after all frame callbacks have finished running. This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail. This should only affect code that calls withFrameNanos or withFrameMillis directly, and has logic outside of callback passed to those functions that may need to be moved inside the callbacks. See the animation test changes in this CL for examples.
  • Added optional onPerformTraversals: (Long) -> Unit parameter to TestMonotonicFrameClock constructor and factory function to run code after withFrameNanos callbacks but before resuming callers' coroutines. ( Idb413 , b/254115946 , b/222093277 , b/255802670 )
  • Added EmojiCompat to Compose ( Ibf6f9 , b/139326806 )
  • Added new wallpaper parameter to @Preview for dynamic colour support ( I9f512 )

رفع اشکالات

  • Snapshot apply notifications are now sent after the Recomposer finishes applying changes. ( Iad6c0 , b/222093277 )
  • Introduced changes in captureToImage to allow for capturing multi window screenshots. This is useful for screenshot tests that use compose PopUps. ( I169c5 )

Dependency Updates

  • Compose UI and Compose Material now depend on Lifecycle 2.5.1. ( I05ab0 , b/258038814 )

Version 1.4.0-alpha02

۹ نوامبر ۲۰۲۲

androidx.compose.ui:ui-*:1.4.0-alpha02 is released. Version 1.4.0-alpha02 contains these commits.

تغییرات API

  • Updated GraphicsLayerScope to expose the current size of the graphicsLayer . This is useful for computing graphicsLayer transformations as a function of the Composable size. ( If8c43 , b/181387080 )
  • Introduced CompositingStrategy to determine when to leverage an offscreen compositing layer for rendering of graphicsLayer content. Auto maintains the default behavior which internally leverages a layer if alpha is applied or a RenderEffect/Overscroll . Always will always introduce an offscreen buffer where ModulateAlpha will avoid leveraging an offscreen buffer and instead will modulate each of the recorded drawing instructions within the graphicsLayer . ModulateAlpha usage will still leverage an offscreen buffer for RenderEffect/Overscroll usages ( I25e82 , b/256382834 )
  • invalidateSubtree() was added to Modifier.Node to allow invalidating entire hierarchies for layout and drawing. ( I4bd90 )
  • Promote rememberNestedScrollInteropConnection to stable. Introduced the ability to pass a root view to rememberNestedScrollInteropConnection . This can help the custom view better react to scrolling constraints, specially in non-standard views (eg ModalBottomSheetDialog ). ( I9e107 )
  • Added ObserverNode interface that can be used by Modifier.Node implementations that need to be notified when a value that they had previously read has changed ( I5728b , b/247716483 )
  • Added a new constructor to Paint that accepts a native android.graphics.Paint . Also added an extension function toComposePaint() that converts an existing native Paint object to Compose Paint. ( Ica91b )
  • Add new FontFamily.Resolver.resolveAsTypeface for use on Android. ( I8950b )
  • Add ToolingState to allow tooling to change internal states of Composable ( Ie6614 )
  • Refactor tooling to have better support for new added animations ( I8677b )
  • پارامتر minLines به material و material3 Text، TextField و OutlinedTextField اضافه شد که امکان تنظیم حداقل ارتفاع کامپوننت بر حسب تعداد خطوط را فراهم می‌کند ( I4af1d )

Version 1.4.0-alpha01

۲۴ اکتبر ۲۰۲۲

androidx.compose.ui:ui-*:1.4.0-alpha01 is released. Version 1.4.0-alpha01 contains these commits.

تغییرات API

  • A new method, awaitEachGesture() , for gesture detectors was added. It operates similar to forEachGesture() , but the loop over gestures operates entirely within the AwaitPointerEventScope so events can't be lost between iterations.
  • forEachGesture() has been deprecated in favor of awaitEachGesture() because it allows events to be lost between gestures. ( Iffc3f , b/251260206 )
  • Deprecating recycling of acccessibility objects in androidx. We've found performance changes to be negligible in even the oldest supported versions. ( I0a961 )
  • Added DrawStyle as an Experimental attribute to TextStyle and SpanStyle to enable drawing outlined text. ( If24b8 , b/155421273 )
  • AnnotatedString.Builder now implements kotlin.text.Appendable . ( I1a061 , b/231030444 )
  • AnnotatedString.Builder now has an append(AnnotatedString, start: Int, end: Int) method to append a substring of an AnnotatedString and the intersecting styles.
  • Added DrawStyle parameter to Paragraph and MultiParagraph paint functions that enables drawing outlined text. ( Ic8102 , b/155421273 )

Modifier Node Refactor

The layer which handles Modifier/Modifier.Element instances and coordinates their behavior on LayoutNodes has been majorly refactored. As it stands this was a refactor which did not affect the public API of any of the many modifiers in Compose, and can be viewed as an implementation-only change. Despite that, this is an important change for various reasons. ( Ie4313 )

خلاصه تغییر

The added experimental Modifier.Node APIs provide an abstraction that allows for state to be maintained on an instance that will be retained with the lifecycle of the layout node, and will be allocated per-layout-node and per-usage of the corresponding Modifier.Element that produced it.

Broadly speaking, this abstraction provides an alternative mechanism to produce stateful modifiers without relying on the mechanics of the Modifier.composed API.

ریسک

This change is strictly binary compatible with prior releases, and is intended to be backwards compatible in terms of observable behavior as much as practical and reasonable. That said, there are few subsystems of compose this refactor did not touch, and it is likely that behavior has changed in ways that were not covered by our tests and have not yet been found and fixed .

Please upgrade to this release with caution. If you believe this has broken something for you, please let us know.

Experimental APIs

Various experimental APIs have been added, all relating to the new concept of a "Modifier Node". Modifier.Node's are created as a result of

  • fun modifierElementOf(…): Modifier
  • abstract class ModifierNodeElement
  • abstract class Modifier.Node
  • abstract class DelegatingNode
  • interface LayoutModifierNode
  • interface DrawModifierNode
  • interface SemanticsNode
  • interface PointerInputNode
  • interface ModifierLocalNode
  • interface ParentDataModifierNode
  • interface LayoutAwareModifierNode
  • interface GlobalPositionAwareModifierNode
  • interface IntermediateLayoutModifierNode

Behavior breaking change

Maximum supported elevation in dialogs and popups has been reduced to 8dp.

The maximum supported elevation for Compose dialogs and popups has been reduced from 30dp to 8dp. This change affects both material and ui custom dialogs and popups. This change is made to mitigate an accessibility bug on Android versions below S, and to ensure that accessibility services within those windows are able to interact with the content inside the dialog or popup.

You will only be impacted by this change if you are creating a custom dialog or popup implementation with an elevation set to levels higher than 8dp. Consider lowering the elevation of your dialog or popup. If you need to opt-out from this new behavior, consider forking your own dialog or popup with the desired elevation set. This is not recommended, as accessibility might be negatively impacted and it is on the developer to ensure the bottom part of the dialog or popup is interactable and readable by accessibility services.

تغییرات API

  • Fixed an issue where painterResource wouldn't update on configuration changes ( I58e73 , b/228862715 )
  • rememberTextMeasurer no longer takes FontFamily.Resolver , Density , or LayoutDirection parameters. Please use the TextMeasurer constructor to provide custom values for these parameters. ( Ia1da3 )

تغییرات API

  • Interfaces in compose libraries are now built using jdk8 default interface methods ( I5bcf1 )
  • Added higher-order functions to KeyInjectionScope for injecting key presses while other keys are held down or toggled on. These functions include withKeysDown , withKeysToggled etc. Also added properties for checking if a particular meta key is down, for example, isCtrlDown to check if either control key is depressed.

تغییرات API

  • Added pressKeyTimes as well as isCapsLockOn and friends to KeyInjectionScope . Additionally, the API now supports mouse and keyboard combined injection patterns such as clicking a mouse button with a meta key held down. ( I4c8da , b/229831515 )
  • Added experimental support for injecting key events. Use performKeyInput to send key events, or send them through the key property of MultiModalInjectionScope during a multi modal input gesture with performMultiModalInput . See KeyInjectionScope for documentation of the API. ( Ic5000 , b/229831515 )
  • Add new GoogleFont.Provider.AllFontsListUri for retrieving the canonical internet source of Google Fonts supported by Android.
  • Improve error messages rethrown when GoogleFonts fail to load in compose. ( I0416c )

رفع اشکالات

  • When adding InputEventChange events to Velocity Tracker we will consider now deltas instead of positions, this will guarantee the velocity is correctly calculated for all cases even if the target element moves ( I51ec3 , b/216582726 , b/223440806 , b/227709803 )

  • Accessibility string lookup does not trigger font loading. Previously, it would attempt to load fonts for StyleSpans , which lead to crashes if FontFamily.Resolver had been overwritten. ( I4609d )
  • Pressing the forward delete key when the cursor is at the end of a text field will no longer crash.
  • DeleteSurroundingTextCommand and DeleteSurroundingTextInCodePointsCommand now require their constructor arguments to be non-negative. ( Ica8e6 , b/199919707 )

ویژگی‌های جدید

  • This is the first beta release of 1.2!

تغییرات API

  • Added experimental BeyondBoundsInterval that can be used by custom implementations of LazyList when they layout items beyond visible bounds ( Ifabfb , b/184670295 )
  • Keyed versions of Modifier.composed are now stable API ( Ie65e4 , b/229988420 )
  • Simplified the rememberNestedScrollConnection API to use composition locals to acquire the current view information ( I67ca7 )
  • The @ComposableTarget annotation and annotations marked by @ComposableTargetMarker can now be used at the file scope using the @file prefix. Using a target annotation at the file scope will cause the compiler to assume all composable functions in the file are intended to be target the associated applier. For example, using @file:UiComposable declares that all @Composable functions target the Compose UI applier. A function that needs to target another applier must explicitly supply the target marker annotation for the desired applier. ( I40804 )

  • Introduced new experimental, platform independent, test API: an interface ComposeUiTest and a fun runComposeUiTest(block: ComposeUiTest.() -> Unit) , that can be used to run Compose Ui tests without the need for a TestRule . To run a test without a ComposeTestRule , pass the test as a lambda to runComposeUiTest , and use the methods and members in the receiver scope ComposeUiTest , which are the same ones as in ComposeContentTestRule .

    The Android specific interface AndroidComposeUiTest and fun runAndroidComposeUiTest(block: AndroidComposeUiTest.() -> Unit) are added to provide access to the underlying Activity, similar to AndroidComposeTestRule . For even more control, you can instantiate a class AndroidComposeUiTestEnvironment yourself.

    The Desktop implementation is the class DesktopComposeUiTest , but no Desktop specific run functions are offered at the moment.

    Migrating a test from a ComposeTestRule to ComposeUiTest can be done like this (Android example). From:

    @RunWith(AndroidJUnit4::class)
class MyTest {
    @get:Rule val rule = createComposeRule()
    @Test
    fun test() {
        rule.setContent {
            Text("Hello Compose!")
        }
        rule.onNodeWithText("Hello Compose!").assertExists()
    }
}

    به:

    @RunWith(AndroidJUnit4::class)
class MyTest {
    @Test
    @OptIn(ExperimentalTestApi::class)
    fun test() = runComposeUiTest {
        setContent {
            Text("Hello Compose!")
        }
        onNodeWithText("Hello Compose!").assertExists()
    }
}

  • For now, ComposeContentTestRule and ComposeTestRule don't extend from ComposeUiTest , which means extension functions on ComposeUiTest can't be called yet on the TestRule interface. When ComposeUiTest graduates to stable API, ComposeContentTestRule and ComposeTestRule will be changed to extend from ComposeUiTest . ( Ib4e90 )

  • LineHeightBehavior is renamed as LineHeightStyle

  • LineVerticalAlignment is renamed as LineHeightStyle.Alignment

  • Renames LineHeightTrim is renamed as LineHeightStyle.Trim

  • Default constructor values from LineHeightStyle is removed ( I582bf , b/181155707 )

  • Added Brush to TextStyle and SpanStyle to provide a way to draw text with gradient coloring. ( I53869 , b/187839528 )

  • trimFirstLineTop , trimLastLineBottom attributes of LineHeightBehavior changed into a single enum: LineHeightTrim . LineHeightTrim have values of 4 states defined by two booleans: FirstLineTop , LastLineBottom , Both and None ( Ifc6a5 , b/181155707 )

  • Added LineHeightBehavior to the TextStyle and ParagraphStyle . LineHeightBehavior controls whether line height is applied to the top of the first line and to the bottom of the last line. It also defines the alignment of line in the space provided by TextStyle(lineHeight) .

    For example it is possible to get a behavior similar to what CSS defines via LineHeightBehavior(alignment = LineVerticalAlignment.Center, trimFirstLineTop=false, trimLastLineBottom = false) .

  • trimFirstLineTop , trimLastLineBottom configurations works correctly only when includeFontPadding is false. ( I97332 , b/181155707 )

  • PlatformParagraphStyle.lerp and PlatformSpanStyle.lerp functions are changed to be top level functions ( I9a268 )

رفع اشکالات

  • PointerInputChange::copy documentation now correctly states that it is a shallow copy. ( I182f5 )
  • Support ellipsis when height is limited and doesn't fit all text lines ( Ie528c , b/168720622 )
  • Turned on default includeFontPadding . It is possible to turn off the includeFontPadding using TextStyle.platformTextStyle attribute. In the near future we will change the default behavior however until that time this allows us to better integrate line height improvements (aosp/2058653) and solve TextField clipping issues. ( I01423 , b/171394808 )

مشارکت خارجی

  • MouseInjectionScope.scroll(delta = someDelta) is now inverted on Android if we scroll vertically (if someDelta is positive, it will scroll downward) ( Ifb697 , b/224992993 )

Version 1.2.0-alpha08

۲۰ آوریل ۲۰۲۲

androidx.compose.ui:ui-*:1.2.0-alpha08 is released. Version 1.2.0-alpha08 contains these commits.

تغییرات API

  • The pluralStringResource functions were marked as experimental in order to allow evolution to support better internationalization in the future. ( If24e4 )
  • Paragraph and MultiParagraph are now accepting Constraints parameter. Passing Constraints.maxHeight is a no-op at the moment but will allow to do some calculation in the future, like ellipsizing based on the height. ( I6afee , b/168720622 )
  • SubcomposeSlotReusePolicy.getSlotsToRetain() now accepts a custom MutableSet-like class which doesn't allow adding new items in it. ( Icd314 )
  • PointerIcon is now a @Stable interface ( I9dafe )
  • Partial consumption (down OR position) has been deprecated in PointerInputChange . You can use consume() to consume the change completely. You can use isConsumed to determine whether or not someone else has previously consumed the change.
  • PointerInputChange::copy() now always makes a shallow copy. It means that copies of PointerInputChange will be consumed once one of the copies is consumed. If you want to create an unbound PointerInputChange , use constructor instead. ( Ie6be4 , b/225669674 )
  • Enable Nested Scroll interop between Compose and View in the direction Compose > View. This means that a compose parent will be able to receive nested scroll deltas from a nested scroll view. ( If7949 , b/174348612 )
  • New SemanticsProperty testTagsAsResourceId , which can be used to make Compose conform with UIAutomator tests designed for the View system. ( I39c20 )
  • Display all available weights for systems fonts on Android when using FontFamily.SansSerif . This will use fallback font names like sans-serif-medium internally on API 21-28. This is a behavior change as previously only weights 400 and 700 were supported on API 21-28. ( I380fe , b/156048036 , b/226441992 )
  • Paragraph and Multiparagraph instructors reordered positional arguments to before optional arguments. ( Idafaa )
  • AndroidFont now takes typefaceLoader as a constructor parameter. ( I2c971 )

Version 1.2.0-alpha07

۶ آوریل ۲۰۲۲

androidx.compose.ui:ui-*:1.2.0-alpha07 is released. Version 1.2.0-alpha07 contains these commits.

تغییرات API

  • New function Snapshot.withoutReadObservation { ... } was added. It allows users to run the passed lambda without subscribing to the changes of the state values read during this block. You could find it useful in use cases when you want to benefit from the snapshot based thread safe write/reads, but want to be able to read the value without causing unnecessary recomposition or remeasure. ( I9f365 , b/214054486 )
  • The consumeWindowInsets extension property of ComposeView allows developers to disable consumption of Android WindowInsets . This allows separate ComposeViews in the hierarchy to each apply WindowInsets without interfering with each other. ( I0ef08 , b/220943142 )
  • Added KeyboardType.Decimal as an alternative to Keyboard.Number for specifically including decimal separator in IME. ( Iec4c8 , b/209835363 )
  • PointerEventType.Scroll and PointerEvent.scrollDelta are stable APIs now ( I574c5 , b/225669674 )
  • Enable Nested Scroll interop between View and Compose for cooperating View classes. This means compose is now able to dispatch scroll deltas to a (cooperating) View parent. ( I5d1ac , b/174348612 )
  • Updated FontFamily.Resolver to integrate System-wide bold text accessibility setting ( I6c1e7 )
  • Font(AssetManager, String, ...) is deprecated, replaced with Font(String, AssetManager, ...) . This is an experimental API. ( I1c7a4 )
  • Add new font descriptor Font(DeviceFontFamilyName) to optionally lookup system-installed fonts during font fallback chains. ( I30468 , b/219754572 )
  • Added temporary compatibility configuration for includeFontPadding in TextStyle/ParagraphStyle. includeFontPadding can be changed via TextStyle(platformStyle = PlatformTextStyle(includeFontPadding = true/false)) . This is a temporary configuration option to enable migration and will be removed. ( If47be , b/171394808 )
  • Add GoogleFont.Provider.isAvailableOnDevice extension for debugging help. ( I64e31 )
  • Add GoogleFont.Provider constructor for use with @ArrayRes ( Ic5ee1 , b/225984280 )
  • Compose GoogleFont is now called Font(GoogleFont) , API remains stable otherwise. ( I125f2 )

رفع اشکالات

  • Added lint check to material/Scaffold to ensure that the inner padding is being used ( Ifb111 )

Version 1.2.0-alpha06

۲۳ مارس ۲۰۲۲

androidx.compose.ui:ui-*:1.2.0-alpha06 is released. Version 1.2.0-alpha06 contains these commits.

تغییرات API

  • Added RequestFocus semantics action to request focus on the focusable target. ( I17b71 )
  • Updated parsing of vector drawables to support auto mirroring to flip the content of a VectorPainter if the current layout direction is RTL. ( I79cd9 , b/185760237 )

  • Updated shadow/ambient colors to be trailing parameters of Modifier.graphicsLayer for API compatibility ( I3f864 , b/160665122 )

  • Added default implementations to shadow/ambient color on GraphicsLayerScope to ensure non-breaking API changes

  • Added event time to RSB events ( Ief8ae )

  • FocusOrder has now been merged into FocusProperties and focusProperties() now has all the capabilities of focusOrder() . FocusOrder and focusOrder() have been deprecated. focusOrder() that accepts a focusRequester should be replaced with a focusRequester() modifier in combination with focusProperties() . This allows the modifiers to have a stronger separation of concerns. ( I601b7 )

  • Upgrading both RecyclerView and Compose will now result in much better scrolling performance for RecyclerViews with Compose views as children.

  • Add ViewCompositionStrategy.Default as a means of retrieving the built-in default strategy

  • Add ViewCompositionStrategy.DisposeOnDetachedFromWindowIfNotInPoolingContainer , which is the new default strategy and properly handles pooling containers such as RecyclerView. ( If7282 )

  • Added support for annotating annotations classes with @Preview as a first step for adding the Multipreview feature. Such annotations could be used to annotate Composable methods or other annotation classes, which could then be considered as indirectly annotated with the given @Preview. ( I12eff )

  • Reference devices added to the Devices list for @Preview ( I071c9 )

رفع اشکالات

  • Updated Vector graphics APIs to use the proper composable annotation @VectorComposable instead of @UiComposable ( I942bc )
  • Remove crossinline from AnnotatedString.Builder.withStyle ( If84d5 )

مشارکت خارجی

  • Measured interface now exposes parentData property ( I3313f )
  • Modifier.onPlaced and the OnPlacedModifier interface are now stable. ( Ib5482 )
  • Hooray! Compose animation now supports 'Animator duration scale' setting from Developer Options. ( I5a4fc , b/161675988 )
  • Added a BeyondBoundsLayout modifier local ( If8b51 , b/184670295 )
  • Text: includeFontPadding is now turned off by default. The clipping issues as a result of includeFontPadding=false is handled and no clipping should occur for tall scripts. ( I31c84 , b/171394808 )

رفع اشکالات

  • ComposeContentTestRule.setContent will now throw an IllegalStateException if you try to set content when there already is content. ( I888a5 , b/199631334 )
  • Fix crash caused by clipboard content while reading from clipboard on Android. ( I06020 , b/197769306 )
  • Improve RSB scrolling samples. ( I6a596 )

  • Updated to use Kotlinx coroutines 1.6.0 ( I3366d )

Version 1.2.0-alpha04

۲۳ فوریه ۲۰۲۲

androidx.compose.ui:ui-*:1.2.0-alpha04 is released. Version 1.2.0-alpha04 contains these commits.

تغییرات API

  • Added ComposableTarget , ComposableTargetMarker and ComposableOpenTarget that allows compile time reporting of when a composable function is called targeting an applier it was not designed to use.

    In most cases the annotations can be inferred by the compose compiler plugin so using these annotation directly should be rare . The cases that cannot be inferred include creating and using a custom applier, abstract composable functions (such as interface methods), fields or global variables that are composable lambdas (local variables and parameters are inferred), or when using ComposeNode or a related composable functions.

    For custom appliers the composable functions that calls ComposeNode or ReusableComposeNode need to add a ComposableTarget annotation for the function and any composable lambda parameter types. It is recommended, however, to create an annotation that is annotated with ComposableTargetMarker and then the marked annotation be used instead of ComposableTarget directly. A composable annotation marked with ComposableTargetMarker is equivalent to a ComposbleTarget with the fully qualified name of the attribute class as the applier parameter. For an example of using ComposableTargetMarker see anroidx.compose.ui.UiComposable . ( I38f11 )

  • Font(resId, ...) now takes loadingStrategy on stable API. ( Ief3d2 )

  • FontLoadingStrategy is now stable API. ( I1ee35 , b/174162090 )

  • Support async font loading in Text ( I77057 , b/214587005 )

  • Add bridge API for converting custom Font.ResourceLoader into FontFamily.Resolver . ( Ia0060 )

رفع اشکالات

  • Provided FontFamily.Resolver are passed to subcompositions such as Popup.
  • Provided Font.ResourceLoader are passed to subcompositions such as Popup. ( I48fa5 )

Version 1.2.0-alpha03

۹ فوریه ۲۰۲۲

androidx.compose.ui:ui-*:1.2.0-alpha03 is released. Version 1.2.0-alpha03 contains these commits.

تغییرات API

  • notifyFocusedRect methods in TextInputSession and TextInputService are now deprecated and won't be called. Use BringIntoViewRequester instead. ( Ia4302 , b/192043120 , b/216842427 , b/178211874 )
  • Introduced destroyDisplayListData method on RenderNode stub class ( I1e659 , b/216660268 )
  • Added a new api which allows to premeasure children of SubcomposeLayout you precomposed. ( I857ea )

  • Added movableContentOf which converts a composable lambda into a lambda that moves it state, and corresponding nodes, to any new location it is called. When the previous call leaves the composition the state is temporarily preserved and if a new call to the lambda enters the composition then the state, and associated nodes, are moved to the location of the new call. If no new call is added the state is removed permanently and remember observers are notified.

    If a movableContentOf lambda is called multiple times in the same composition, new state and nodes are created for each call and, as calls leave the composition and new calls enter, the state is moved from the first leaving calls to the entering calls in the order they are called. All state not claimed by new calls is removed permanently. ( Ib4850 )

  • FontFamilyResolver is now available via LocalFontFamilyResolver.current

  • Added createFontFamilyResolver(context) and createFontFamilyResolver(context, coroutineScope) to create new FontFamily resolvers outside of compose usage.

  • Paragraph and MultiParagraph now take FontFamily.Resolver

  • TextLayoutResult.layoutInput.fontFamilyResolver now contains the resolver used for this layout, deprecated TextLayoutResult.layoutInput.resourceLoader as it is no longer used. ( Id5a45 , b/174162090 )

  • Support for async and optional font loading, with fallback behavior. This path is used by Text and TextField, and exposed through FontFamilyResolver

  • Support for preloading fonts via FontFamilyResolver.preload

  • FontFamilyResolver.setAsyncLoadContext allows setting the global coroutine context used for loading async fonts. ( I87fe8 , b/174162090 )

  • Added AndroidFont , a new low-level API for providing new types of font resource descriptors on Android. For example, loading fonts from an app-specific backend, optionally locating pre-installed fonts on-device, or loading a font from a resource not provided by the current Font factories.

  • Expanded Font.ResourceLoaded API to support optional and async font loading. It is not recommended that application developers use this API directly. To add new types of fonts see AndroidFont .

  • Font.AndroidResourceLoader extension function allows construction of a Font.ResourceLoader when outside of composition.

  • Added loadingStrategy parameter to resource-based fonts, to allow async loading when resource font references downloadable fonts XML. ( Ie5aea , b/174162090 )

  • Typeface(FontFamily) constructor is deprecated. This was previously used to preload fonts, which may take up to 10 seconds for downloadable fonts. With downloadable fonts, this call may block for 10 seconds. Instead use FontFamilyResolver.preload .

  • fontResource(FontFamily): Typeface is deprecated. This was previously used to preload fonts, which may take up to 10 seconds for downloadable fonts. Instead use FontFamilyResolver.preload ( If8e7c , b/174162090 )

  • SubcomposeLayoutState constructor accepting maxSlotsToRetainForReuse is now deprecated. Instead there is a new constructor accepting SubcomposeSlotReusePolicy - a new interface allowing more granular control on what slots should be retained for the future reuse. ( I52c4d )

  • Exposes HSV and HSL function in Color as non-experimental API. The Oklab color space is now public API. ( I08fb6 , b/180731008 )

نسخه ۱.۱.۱

۲۳ فوریه ۲۰۲۲

androidx.compose.ui:ui-*:1.1.1 is released. Version 1.1.1 contains these commits.

رفع اشکالات

نسخه ۱.۱.۰

۹ فوریه ۲۰۲۲

androidx.compose.ui:ui-*:1.1.0 is released. Version 1.1.0 contains these commits.

Important changes since 1.0.0

  • Stable support for the Android 12 Overscroll effect
  • Improvements to touch target sizing
    • Note that, with respect to Compose 1.0, Material components will expand their layout space to meet Material accessibility guidelines for touch target size . For instance, Button touch target will expand to a minimum size of 48x48dp, even if you set the Button's size to be smaller. This aligns Compose Material to the same behavior of Material Design Components, providing consistent behavior if you mix Views and Compose. This change also ensures that when you create your UI using Compose Material components, minimum requirements for touch target accessibility will be met.
  • Stable Support for Navigation Rail
  • Graduates a number of previously experimental APIs to stable
  • Support for newer versions of Kotlin

  • SemanticsNodeInteraction.captureToImage() will now also work if HardwareRenderer.isDrawingEnabled() is false , by enabling it for the duration of the call ( Idf3d0 )

Version 1.1.0-beta04

۱ دسامبر ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-beta04 is released. Version 1.1.0-beta04 contains these commits.

ویژگی‌های جدید

  • Updated to be compatible with Kotlin 1.6.0

تغییرات API

  • Cleaned up nullability in androidx.core.view ( I7078a , b/204917439 )
  • Experimental APIs were added that allow users to consume PointerInputchange as a whole or check whether it was consumed or not. ( I2e59d )
  • Adds support for mouse scroll wheel events in the UI layer. ( Ia14eb , b/198214718 )
  • Add experimental Modifier.composed overloads that accept keys to compare for equality and qualify for skipping optimizations. ( Ice799 , b/205851704 )
  • ComposeNotIdleException now extends from Exception instead of directly from Throwable . Note that this means that catch clauses that were catching Exception might now catch ComposeNotIdleException s, where they wouldn't do that previously. ( I9c217 )

رفع اشکالات

  • Fix text handles not moving when IME visibility changes. ( I25f2e )

Version 1.1.0-beta03

۱۷ نوامبر ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-beta03 is released. Version 1.1.0-beta03 contains these commits.

تغییرات API

  • Added new modifier Modifier.onPlaced to allow placement change to be observed. Additional changes to child modifier's offset can therefore be made based on the observed placement change. ( I558fd )
  • Removed InjectionScope.flush() and InjectionScope.dispose() . Flushing of all events and disposing of the scope now happens at the end of the called perform*Input() method like before. ( I2bed8 )
  • Removed MultiModalInjectionScope.Touch and MultiModalInjectionScope.Mouse . In order to inject touch and mouse events for multi-modal gestures, you can now use MultiModalInjectionScope.touch() and MultiModalInjectionScope.mouse() , both of which accept a lambda that has the receiver scope of that modality. ( Idde18 )

رفع اشکالات

  • The default value for durationMillis in TouchInjectionScope.swipeWithVelocity is now calculated such that the swipe is feasible. ( I19deb )

Version 1.1.0-alpha06

۱۳ اکتبر ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-alpha06 is released. Version 1.1.0-alpha06 contains these commits.

تغییرات API

  • Remove ExperimentalComposeUiApi from ViewRootForInspector and LayoutInfo.ownerViewId ( I5c2e3 )
  • A child-less overload for Layout was added, with improved efficiency ( Ib0d9a )
  • Removed InternalCompilerApi from Composer methods that are required to be called cross-module ( I1aa0b )
  • SemanticsNodeInteraction.performSemanticsAction now returns the SemanticsNodeInteraction on which the function was called. ( I9e5db )
  • Added LocalInputModeManager CompositionLocal to detect TouchMode/NonTouchMode. ( I6a83c , b/175899786 )
  • Added viewConfiguration: ViewConfiguration to LayoutInfo to allow consumers get the correct value for things like long press timeout. ( I76ca6 )
    • Added viewConfiguration: ViewConfiguration to InjectionScope to allow tests to adjust input injection based on things like long press timeout or touch slop.
    • Changed default duration of long press and double tap for both touch and mouse input to be based on the values in InjectionScope.viewConfiguration .
  • Implementation of ExposedDropdownMenu based on ExposedDropdownMenuBox with TextField and DropdownMenu inside ( If60b2 )
  • dismissOnOutsideClick was added to PopupProperties, replacing dismissOnClickOutside which was deprecated. The new property receives the click position and the anchor bounds, providing finer control over whether onDismissRequest should be invoked or not. For example, this can be useful to prevent anchor dismissal for touches on the anchor.
    • updateAndroidWindowManagerFlags was added to PopupProperties, offering low-level control over the flags passed by the popup to the Android WindowManager. The parameter of the lambda will be the flags calculated from the PopupProperties values that result in WindowManager flags: eg focusable. The result of the lambda will be the final flags which will be passed to the Android WindowManager. By default, updateAndroidWindowManagerFlags will leave the flags calculated from parameters unchanged. This API should be used with caution, only in cases where the popup has very specific behavior requirements. ( I6e9f9 )
  • Recomposer.state has been deprecated and replaced by Recomposer.currentState to change its type to a StateFlow ( Ic2ab3 , b/197773820 )
  • Added flush() and dispose() to InjectionScope . Use them when you want to flush all queued up events immediately and when you want to dispose of the scope, respectively. ( Ifb73a )
  • Added performScrollToNode(matcher: SemanticsMatcher) that scrolls a scrollable container to the content that is matched by the given matcher. ( Ic1cb8 )
  • InjectionScope now implements Density , allowing you to easily convert between px and dp in performTouchInput and friends. ( I8fe1f )

رفع اشکالات

  • AndroidView now propagates LocalLifecycleOwner and LocalSavedStateRegistryOwner to its view via ViewTreeLifecycleOwner and ViewTreeSavedStateRegistryOwner. ( I38f96 , b/179708470 )
  • Fix WearOS SwipeToDismissBox sometimes not handling swipes. ( I9387e )
  • The default time between injected input events has been changed from 10ms to 16ms. This potentially changes the outcome of tests that perform input gestures, like a specific swipe. ( I829fd )

Version 1.1.0-alpha05

۲۹ سپتامبر ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-alpha05 is released. Version 1.1.0-alpha05 contains these commits.

تغییرات API

  • Added support for inter-modifier communication ( Id5467 , b/198826874 )
  • Added experimental historical pointers to PointerEventChange. ( Ic1fd8 , b/197553056 , b/199921305 )
  • Added density: Density and layoutDirection: LayoutDirection to LayoutInfo . This allows consumers of LayoutInfo to interpret the dimensions and position exposed in LayoutInfo properly. ( I002f1 )
  • Added experimental support for injecting mouse events. Use performMouseInput to start sending mouse events, or send mouse events through the Mouse property of MultiModalInjectionScope during a multi modal input gesture with performMultiModalInput . See MouseInjectionScope for documentation of the available API. ( Iaa4a8 , b/190493367 )

رفع اشکالات

  • Fixed accessibility support for scrollables (both lazy and non-lazy) with respect to scrolling ( I6cdb0 )
  • Improved TouchInjectionScope.swipeWithVelocity . It now accepts a wider range of input variables and will suggest changes to the input if a swipe can't be created ( I40fbe , b/182477143 )

Version 1.1.0-alpha04

۱۵ سپتامبر ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-alpha04 is released. Version 1.1.0-alpha04 contains these commits.

تغییرات API

  • PointerEvent now has a PointerEventType to support hover events. ( I091fa )
  • Allow children to accept pointer input outside of parent's pointer input bounds. Parents may intercept those calls with a property PointerInputScope.alwaysInterceptChildEvents ( I9eae3 , b/192479655 )
  • Deprecated performGesture and GestureScope , which have been replaced by performTouchInput and TouchInjectionScope . ( Ia5f3f , b/190493367 )
  • Added touchBoundsInRoot to SemanticsNode that includes the minimum touch target size so that developers can ensure that touch targets meet accessibility minimums. ( I2e14b , b/197751214 )
  • Redo implementation of inspectable ( I927bc , b/191017532 )
  • Changed parameter name of inspectable to match composed ( I3a482 , b/191017532 )

  • Introduced performTouchInput and TouchInjectionScope as a replacement for performTouchInput and TouchInjectionScope , paving the way for other modalities (like mouse).

    TouchInjectionScope has the same methods as GestureScope , with the exception of movePointerTo and movePointerBy , which have been renamed to updatePointerTo and updatePointerBy . All other methods are the same.

    The behavior of TouchInjectionScope is almost identical to GestureScope , with two small details:

    1. When sending a down event while pointers had been moved without sending a move event (in other words, updatePointerTo() has been used, but not move() , and then down() is called), the previous implementation would advance the event time and send a move event before sending the down event. The new implementation still sends the move event, but doesn't advance the event time in this specific scenario.
    2. When sending an up event while pointers had been moved without sending a move event (similar as above), the previous implementation would advance the event time and send a move event before sending the up event. The new implementation does neither: the new positions of the pointers will only be reflected through the up event.

    Finally, TouchInjectionScope introduces a new method currentPosition(pointerId: Int) to get the current position of the given pointer. ( If1191 , b/190493367 )

رفع اشکالات

  • Allow clip to extend touch target bounds beyond the clip region for minimum touch target purposes. ( I43e10 , b/171509422 )
  • Support for stretch overscroll has been added on Android 12 devices. ( Iccf3c , b/171682480 )

Version 1.1.0-alpha03

۱ سپتامبر ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-alpha03 is released. Version 1.1.0-alpha03 contains these commits.

ویژگی‌های جدید

  • Updated Compose 1.1.0-alpha03 to depend on Kotlin 1.5.30 . ( I74545 )

تغییرات API

  • Added Modifier.inspectable for wrapping other modifiers. ( I1909b , b/191017532 )
  • Added BlurredEdgeTreatment API to simplify blur use cases into more commonly used combinations of clip flags and TileModes. Most use cases involve either letting blurred content render outside the original content bounds and blurring regions outside these bounds with transparent black, or clipping content to content bounds sampling the closest edge for blur kernels that extend beyond content bounds. ( I6b4b7 , b/166927547 )
  • Added support for RenderEffect in compose desktop. Introduced OffsetEffect as well as the blur modifier as a simple way to introduce blur visual effects to a portion of the composition hierarchy. ( I0f6aa , b/166927547 )
  • Introduced RenderEffect API that can be optionally configured on a Modifier.graphicsLayer to alter the contents of the layer itself. This can be used to blur contents of a composable and child composables within a composition hierarchy. ( I47c4d , b/166927547 )
  • AwaitPointerEventScope now has withTimeout() and withTimeoutOrNull() ( I507f0 , b/179239764 , b/182397793 )
  • Added minimum touch target size to ViewConfiguration for use in semantics and pointer input to ensure accessibility. ( Ie861c )
  • Add TileMode.Decal support which is useful in defining edge behavior for blur based RenderEffects. ( I7e8ed , b/166927547 )
  • performScrollToIndex , performScrollToKey , hasScrollToIndexAction and hasScrollToKeyAction are now stable API ( I142ae , b/178483889 )
  • Added test method to get the clipped bounds. ( I6b28e )

رفع اشکالات

  • Removed isBounded method from BlurredEdgeTreatment in favor of explicitly checking if the shape parameter is null. ( I85d68 )

Version 1.1.0-alpha02

۱۸ آگوست ۲۰۲۱

androidx.compose.ui:ui-*:1.1.0-alpha02 is released. Version 1.1.0-alpha02 contains these commits.

تغییرات API

  • PointerEvent now has support for reading mouse button state and keyboard modifier state. ( I6310c , b/180075467 )
  • Injected gestures now use the MainTestClock's time as the source of truth for time. The current time for injected events in performGesture will be initialized to the current time of the MainTestClock. ( Ifb364 , b/192064452 )
  • Added DpRect(DpOffset, DpSize) constructor ( I2cf16 , b/194219828 )
  • Added DpSize class ( I7abb1 , b/194219828 )

androidx.compose.ui:ui-*:1.1.0-alpha01 is released. Version 1.1.0-alpha01 contains these commits.

تغییرات API

  • RelocationRequester.bringIntoView now accepts a rectangle as a parameter which enables us to bring a part of a composable into view ( Ice2c5 , b/194330245 )
  • AnimatedImageVector and the related APIs are now in the new androidx.compose.animation:animation-graphics module. ( I60873 )
  • Added experimental modifier to handle relocation requests. ( I65a97 , b/178211874 )

  • Introduced BrushPainter API to support drawing of an arbitrary Brush within a Painter, similar to ColorPainter

    Updated Brush API to have an intrinsic size parameter that is queried within BrushPainter ( Ia2752 , b/189466433 )

  • Updated DrawScope#drawImage method that consumes source and destination rects to consume an optional FilterQuality parameter. This is useful for pixel art that is intended to be pixelated when scaled up for pixel based art. Updated BitmapPainter + Image composable to also consume an optional FilterQuality parameter ( Ie4fb0 , b/180311607 )

  • Added GestureScope.advanceEventTime method to give more control over the timing of events in a gesture ( Ibf3e2 )

رفع اشکالات

  • In order to better support chaining of draw modifiers, make sure the Modifier.paint implementation calls drawsContent. Previously Modifier.paint was expected to a leaf node in the chain of Modifiers, however, by doing so it prevents it from being configured on a composable container (ex. box) or adding additional decorations on top such as Modifier.paint().border() . By having Modifier.paint call drawContent after drawing the contents of the given painter, we have better behavior consistency in behavior with the modifier pattern. ( Ibb2a7 , b/178201337 , b/186213275 )
  • Dialogs now follow the platform sizing behaviour. Set usePlatformDefaultWidth to false to override this behaviour. ( Iffaed , b/192682388 )
  • Moved InfiniteAnimationPolicy to :compose:ui ( I5eb09 , b/160602714 )
  • Scrolling via semantics actions for lazy lists and regular scrolling components is now animated ( Id9066 , b/190742024 )

Version 1.0.0-beta09

۱۶ ژوئن ۲۰۲۱

androidx.compose.ui:ui-*:1.0.0-beta09 is released. Version 1.0.0-beta09 contains these commits.

تغییرات API

  • Change enum Role and LiveRegionMode into inline classes with private constructor ( Id1890 )
  • KeyboardCapitalization is converted into an inline class. ( Id5a1c )
  • Change HapticFeedbackType to inline class. ( I255ec )
  • Modifier.pointerInteropFilter is @ExperimentalComposeUiApi. ( Iede6c )
  • TextAlign, FontSynthesis and TextDirection are now inline classes. ( I212fe )
  • TextOverflow is changed to an inline class. ( I433af )
  • FontStyle is now an inline class. ( I9e48b )

رفع اشکالات

  • Key constants are @ExperimentalComposeUiApi for now. Consuming code can declare private constants prior to stabilization. ( Ia5d48 )
  • Compose tests can now be run on Robolectric. The following limitations have so far been identified:
    • There is no native bitmap, so ImageBitmap() leads to a NullPointerException.
    • There is no drawing, so captureToImage() will indefinitely await the next draw pass (ie it deadlocks).
    • There is no font loaded, so any text will be measured incorrectly. All characters have a fixed height of around 20px and width of 1px.
    • ComposeTestRule.waitUntil {} does not run the main thread while it's waiting, making it effectively the same as ComposeTestRule.mainClock.advanceTimeUntil {} More limitations are expected to be identified in the future. ( I284fa )

Added Profile Rules

This release adds profile rules to the following compose modules ( I14ed6 ):

  • androidx.compose.animation
  • androidx.compose.animation-core
  • اندروید ایکس.کامپوز.فونداسیون
  • androidx.compose.foundation-layout
  • اندروید.کامپوز.متریال
  • androidx.compose.material-ripple
  • androidx.compose.runtime
  • androidx.compose.ui
  • androidx.compose.ui.geometry
  • androidx.compose.ui.graphics
  • androidx.compose.ui.text
  • androidx.compose.ui.text
  • androidx.compose.ui.unit
  • androidx.compose.ui.util

What are profile rules?

  • Profile rules for a library are specified in a text file baseline-prof.txt located in the src/main or equivalent directory. The file specifies a rule per line, where a rule in this case is a pattern for matching to methods or classes in the library. The syntax for these rules is a superset of the human-readable ART profile format that is used when using adb shell profman --dump-classes-and-methods ... . These rules take one of two forms to target either methods or classes.

  • A method rule will have the following pattern:

    <FLAGS><CLASS_DESCRIPTOR>-><METHOD_SIGNATURE>

  • And a class rule will have the following pattern:

    <CLASS_DESCRIPTOR>

  • Here <FLAGS> is one or more of the characters H , S , and P to indicate whether or not this method should be flagged as "Hot", "Startup", or "Post Startup".

  • The <CLASS_DESCRIPTOR> is the descriptor for the class that the targeted method belongs to. For example, the class androidx.compose.runtime.SlotTable would have a descriptor of Landroidx/compose/runtime/SlotTable; .

  • The <METHOD_SIGNATURE> is the signature of the method, and includes the name, parameter types, and return types of the method. For example, the method fun isPlaced(): Boolean on LayoutNode has the signature isPlaced()Z .

  • These patterns can have wildcards ( ** , * , and ? ) in order to have a single rule encompass multiple methods or classes.

What do the rules do?

  • A method that has the flag H indicates that this method is a "hot" method, and should be compiled ahead of time.

  • A method that has the flag S indicates that it is a method which is called at startup, and should be compiled ahead of time to avoid the cost of compilation and interpreting the method at startup time.

  • A method that has the flag P indicates that it is a method which is called after startup.

  • A class that is present in this file indicates that it is used during startup and should be pre-allocated in the heap to avoid the cost of class loading.

این چطور کار می‌کند؟

  • Libraries can define these rules which will be packaged in AAR artifacts. When an app is then built which includes these artifacts, these rules are merged together and the merged rules are used to build a compact binary ART profile that is specific to the app. ART can then leverage this profile when the app is installed on devices in order to ahead-of-time compile a specific subset of the application to improve the performance of the application, especially the first run. Note that this will have no effect on debuggable applications.

Version 1.0.0-beta08

تغییرات API

  • NestedScrollSource enum is replaced by an inline class. ( Ie321b , b/187055290 )
  • FocusManager.clearFocus(forcedClear = true) is renamed to FocusManager.clearFocus(force = true) ( Ia0c41 )

  • Remove @ExperimentalComposeUiApi from PopupProperties . ( I01fa6 )
  • PointerType was changed from an enum to an inline class ( If5058 )
  • ContentDescription and Text semantics properties are no longer single values but lists. This enables to merge them as they are instead of concatenations. Also provided better testing APIs to utilize these changes ( Ica6bf , b/184825850 )
  • Modifier.focusModifier() is deprecated and replaced by Modifier.focusTarget() ( I6c860 )

    • TextUnit constructor with TextUnitType is now ExperimentalTextApi instead of ExperimentalComposeApi.

رفع اشکالات

  • Fixed the bug introduced in beta07 where LazyColumn/Row items were displayed partially after the scroll ( I8c9ac , b/188566058 )
  • Now detectDragGesures , detectVerticalGestures , and detectHorizontalGestures will consume the position change automatically, no need to call change.consumePositionChange in the onDrag callbacks ( I42fc4 , b/185096350 , b/187320697 )
  • LayoutModifiers providing alignment lines was fixed. A bug causing the parent not being remeasured when the alignment lines of the children were changing was fixed. ( I4401f , b/174315652 )
  • Modifier.onGloballyPositioned() was changed to report the coordinates of this modifier in the modifier chain, not the layout coordinates after applying all the modifiers. This means that now the ordering of modifiers is affecting what coordinates would be reported. ( Ieb67d , b/177926591 )

Version 1.0.0-beta07

  • Introduces ability to hoist the SubcomposeLayout state which allows you to precompose the content into a requires slotId which would make the next measure pass faster as once we try to subcompose with the given slotId next time there will be no composition needed. ( I42580 , b/184940225 )
  • Added Clip Selection Handle ( Iff80d , b/183408447 )
  • Removed unused APIs related to LayoutInspector support. ( I2ac78 )

رفع اشکالات

  • LazyColumn/Row will now keep up to 2 previously visible items active (not disposed) even when they are scrolled out already. This allows the component to reuse the active subcompositions when we will need to compose a new item which improves the scrolling performance. ( Ie5555 )

۲۴ فوریه ۲۰۲۱

androidx.compose.ui:ui-*:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

This is the first release of Compose 1.0.0 Beta.

تغییرات API

  • onStart callback has been added to detectDragGestures ( I67269 , b/179995594 )
  • Modifiers for sizing to intrinsics are no longer experimental. ( I15744 )
  • MeasureBlocks was renamed to MeasurePolicy which became a fun interface. Layout APIs were updated / simplified to use MeasurePolicy. ( Icab48 , b/167662468 , b/156751158 )
  • InteractionState has been replaced with [Mutable]InteractionSource
    • Interfaces are responsible for emitting / collecting Interaction events.
    • Instead of passing interactionState = remember { InteractionState() } to components such as Button and Modifier.clickable() , use interactionSource = remember { MutableInteractionSource() } .
    • Instead of: Interaction.Pressed in interactionState you should instead use the extension functions on InteractionSource, such as InteractionSource.collectIsPressedAsState().
    • For complex use cases you can use InteractionSource.interactions to observe the stream of Interactions. See the InteractionSource documentation and samples for more information.
    • ( I85965 , b/152525426 , b/171913923 , b/171710801 , b/174852378 )
  • Add AccessibilityMananger interface and LocalAccessibilityMananger in CompositionLocals ( I53520 )
  • Removed deprecated LayoutCoordinates methods, use function instead of the property for positionInParent and boundsInParent ( I580ed , b/169874631 , b/175142755 )
  • Typealiases replaced by underlying types:
    • ColorStop is now Pair<Float, Color>
    • SpanStyleRange is now `AnnotatedString.Range
    • ParagraphStyleRange is now AnnotatedString.Range<ParagraphStyle>
    • StringAnnotation is now AnnotatedString.Range<String>
    • ( I8dd1a )
  • Created new TextInputSession for input sessions from low level text components such as CoreTextField. ( I8817f , b/177662148 )
  • Placeable now exposes measuredSize, representing the size which the child layout actually measured to. This size might not respect the measurement constraints. ( Ib2729 , b/172560206 , b/172338608 )
  • Add selectionGroup modifier that allows to mark collection of Tabs or RadioButtons for accessibility purposes ( Ie5c29 )

  • The defaultFactory for compositionLocalOf and staticCompositionLocalOf is now required instead of optional.

    This changes removes a potential type error for non-nullable types where no default factory was provided. Previously this would provide a null reference for a non-nullable type.

    For nullable types consider supplying { null } as the default factory.

    We do not recommend using locals with non-nullable types unless a sensible default can be provided. If no sensible default exists, the defaultFactory lambda should throw an exception. However throwing an exception means that consumers of the local will have an implicit dependency on it being provided that is not enforced by the type system. ( Ifbd2a )

  • Deprecated methods from ui modules were removed ( I646f6 )

  • Size modifiers were renamed. Modifier.width/height/size were renamed to requiredWidth/requiredHeight/requiredSize. Modifier.preferredWidth/preferredHeight/preferredSize were renamed to width/height/size. ( I5b414 )

    • The Composition constructor no longer accepts a key parameter, and has been deprecated.
    • currentCompositeKeyHash has been turned into a composable top level property instead of a composable top level function.
    • CompositionData and CompositionGroup have been moved to the androidx.compose.runtime.tooling namespace
    • ComposableLambda has been made an interface instead of a concrete class, and no longer has type parameters.
    • ComposableLambdaN has been made an interface instead of a concrete class, and no longer has type parameters.

  • Deleted some previously deprecated APIs ( Ice5da , b/178633932 )

  • longPressGestureFilter and doubleClickGestureFilter have been removed. use Modifier.pointerInput with helper functions eg detectTapGestures ( I2fedf , b/175294473 )

    • Renamed bodyContent parameters in a few components to just content .
    • Reordered parameters in ButtonDefaults.buttonColors() . Please note that because the type of the parameters have not changed, this will not cause an error in your code - please ensure you are either using named parameters or update the ordering manually, otherwise your code will not work the same as previously.
    • Added secondaryVariant parameter to darkColors() . This color is typically the same as secondary in dark theme, but adding for consistency and further customization.
    • Removed ElevationDefaults and animateElevation() from the public API surface since they were not commonly used / useful.

  • Testing update: hasText() will check for both input and label/hint/placeholder texts in the text field ( Iab803 )
  • viewModel() composable and LocalViewModelStoreOwner were moved to androidx.lifecycle.viewmodel.compose. You will now need to add a separate dependency androidx.lifecycle:lifecycle-viewmodel-compose:1.0.0-alpha01 in order to use it. ( I7a374 )
  • Allow nullable action in AccessibilityAction, change action label in AccessibilityAction and CustomAccessibilityAction from CharSequence to String ( I0dc82 )
  • In order to better match naming conventions with ImageBitmap and ImageVector, ImagePainter has been renamed to BitmapPainter to parallel VectorPainter. ( Iba381 , b/174565889 )
  • Better substring test APIs with substring now as an argument ( Icbe78 )
  • Added an Modifier.focusOrder() that accepts a FocusRequester without specifying a custom focus order a lambda. This is useful when we only need to specify a reference but not a custom focus order for a composable ( I4f52a , b/179180978 )
  • ComponentActivity.setContent has moved to androidx.activity.compose.setContent in the androidx.activity:activity-compose module. ( Icf416 )

  • Similarly to how we previously removed state { 0 } composable and now promote usage like remember { mutableStateOf(0) } we are going to remove savedInstanceState { 0 } composable. You should use rememberSaveable { mutableStateOf(0) } instead and it will save and restore automatically if the type used inside the MutableState can be stored in the Bundle. If previously you were passing a custom saver object now you need to use a new overload of rememberSaveable which has stateSaver parameter. The usage will look like this: val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) } ( Ib4c26 , b/177338004 )
  • Added password semantics for accessibility ( I231ce )
  • Added ProgressBarRangeInfo.Indeterminate to mark indeterminate progress bars for accessibility ( I6fe05 )

  • Removed CoreText and CoreTextField from public API
    • Removed deprecated SelectionContainer overload
    • ( I99c19 )
  • Tests in which Compose is used in hierarchies that are added/removed directly to the WindowManager are now more stable. ( Ie81ed , b/175765614 )

  • The API the Compose compiler plugin targets has been refactored to use an interface instead of a concrete class. The interface also no longer uses a type parameter.

    This is an internal change that should not effect source code compatibility but is a binary breaking change. ( I3b922 , b/169406779 )

  • Remove unintentionally public StringBuilder.deleteAt function ( Id6ed9 )

رفع اشکالات

  • ComposeViews placed in view hierarchies that are children of another composition now host child compositions of their ancestors ( I92883 )

  • Updated GraphicsLayerScope implement density to support conversions of dp into raw pixels. ( Ied528 , b/176819695 )
  • Updated matrix API to follow row major ordering and provide index constants to assist with conversions between different matrix representations to match framework conversion logic between SkMatrix and Matrix4 internally. ( I432e6 )

رفع اشکالات

  • onCommit, onDispose, and onActive have been deprecated in favor of SideEffect and DisposableEffect APIs ( If760e )

  • Changes to factory functions for Font/FontFamily/Typeface

    • Added factory functions that start with capital letter
    • Deprecated previous factory functions with lowercase first letters
    • New factory functions return the FontFamily instead of subclasses
    • Hid constructors of the subclasses, so that they can only be constructed via factory functions.
    • Renamed Font.asFontFamily to Font.toFontFamily ( I42aa7 )

  • Introduced ComposeContentTestRule , which extends ComposeTestRule and defines setContent , which has been removed from ComposeTestRule . Added a factory method createEmptyComposeRule() that returns a ComposeTestRule and does not launch an Activity for you. Use this when you want to launch your Activity during your test, eg using ActivityScenario.launch ( I9d782 , b/174472899 )

  • animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. eg Float, Dp, Offset, etc ( Ie7e25 )

  • Content description parameter has been added to the Image and Icon. It is used to provide description to the accessibility services ( I2ac4c )

  • Remove displaySize as it should be avoided. Typically it is better to use size of onRoot() or window size at least. ( I62db4 )

  • OnSizeChanged was reporting the size of the layout's contents. It now reports the size at its position within the modifier chain. ( I36b78 , b/177562900 )

  • The emit() API and all overloads have been deprecated and renamed to ComposeNode. The APIs are identical, just a different name in order to follow the naming conventions of Compose ( I4137b )

  • TextFieldValue accepts AnnotatedString. However this is an API only change and multi-style text editing is not implemented yet.

    • Removed initial from EditingBuffer constructor parameters. ( I326d5 )

  • invalidate and compositionReference() are now deprecated in favor of currentRecomposeScope and rememberCompositionReference respectively. ( I583a8 )

  • AnnotatedString is changed to extend from kotlin.CharSequence. Therefore length and subSequence are now instance functions, and extension functions are removed. ( Iaf429 )

  • RememberObserver replaces CompositionLifecycleObserver and CompositionLifecycleObserver is now deprecated.

    RememberObserver is a replacement for CompositionLifecycleObserver with modified semantics and renamed methods. Changing to the new API can be done mechanically for objects that are only remembered once which is, and continues to be, the recommended practice. However, if a reference was remembered more than once in a composition onRemembered is called for each reference where onEnter is only called once. onEnter was called multiple time if the object was used in subcompositions, such as WithConstraints and Scaffold making the single onEnter call guarantee unreliable and it was removed for RememberObserver .

    RememberObserver adds onAbandoned which is called if the RememberObserver instance is returned from the callback passed to remember but was not remembered in the composition state and, therefore, will never have onRemembered called. This can occur if an exception terminates composition before completing or the composition is discarded because the state is was producing a composition for is no longer current or otherwise is no longer needed. If the instance of RememberObserver following the single reference recommendation above is tracking an external resource both onForgotten and onAbandoned each indicate that the resource is no longer needed. If the object is tracking work started or resources allocated in onRemembered , onAbandoned can be ignored as it will not be called if onRemembered is called. ( I02c36 )

  • Deprecated arithmetic operations between 2 or more TextUnits. Deprecated TextUnit.Sp and TextUnit.Em functions in preference to the extension functions such as Int.sp and Int.em. ( I48369 )

  • Resources in libraries with no explicitly declared public resources (ex. via public.xml) are now private by default. ( Ia1dcc , b/170882230 )

  • ScrollableColumn/Row were deprecated. Using ScrollableColumn is less efficient compared to LazyColumn when you have a large scrolling content because with LazyColumn we can only compose/measure/draw visible elements. To prevent users from going the inefficient way we decided to deprecate ScrollableColumn and ScrollableRow and promote usages of LazyColumn and LazyRow instead. Users can still decide they don't need the lazy behaviour and use the modifiers directly like this: Column(Modifier.verticalScroll(rememberScrollState())) ( Ib976b , b/170468083 )

  • New items(count: Int) factory method for scope of LazyColumn/LazyRow/LazyVerticalGrid. items(items: List) and itemsIndexed(items: List) are now extension functions so you have to manually import them when used. New extension overloads for Arrays: items(items: Array) and itemsIndexed(Array) ( I803fc , b/175562574 )

  • Please use ImeAction.None instead of ImeAction.NoAction

    • Please use ImeAction.Default instead of ImeAction.Unspecified ( Ie1bcc )

  • Leverage TestCoroutineDispatcher in testing ( I532b6 )

  • Renamed TextInputService.onStateUpdated as updateState ( Id4853 )

  • TransitionDefinition-based Transition has been deprecated ( I0ac57 )

  • TextUnitType.Inherit is removed. Please use TextUnitType.Unspecified instead. ( I9ff64 )

شکستن تغییر

  • Restructuring of the internal compiler API allows batching changes to the nodes generated as a result of composition into the "apply changes" phase of composition, after all @Composable functions have completed.

    This is a behavioral breaking change that might affect application code as nodes are no longer available from internal and experimental APIs until after changes have been applied. This can usually be worked around by surrounding code with such dependencies in a SideEffect composable to defer execution of the code until after the nodes have been created and initialized. ( I018da )

تغییرات API

Version 1.0.0-alpha09

۱۶ دسامبر ۲۰۲۰

androidx.compose.ui:ui-*:1.0.0-alpha09 is released. Version 1.0.0-alpha09 contains these commits.

تغییرات API

  • Deprecated KeyEvent.Alt is now removed. Use KeyEvent.isAltPressed instead. ( Idd695 )
  • Modifier.keyInputFilter and Modifier.previewKeyInputFilter are deprecated use Modifier.onKeyEvent and Modifier.onPreviewKeyEvent instead ( Idbf1b , b/175156384 )

  • The Applier interface has changed to simplify building trees bottom-up instead of top-down.

    The insert() method has been renamed to insertTopDown() .

    A new method, insertBottomUp() , was added.

    An applier either inserts nodes into the tree it is editing using insertTopDown() or insertBottomUp() depending on which performs better.

    Some trees, such as LayoutNode and View , are much more efficient to build bottom-up than top-down. Prior to this change, a stack of inserts was required to implement bottom-up which needed to be copied to every applier which needed bottom-up construction for performance. With this change an Applier overrides insertBottomUp() to build a tree bottom-up and insertTopDown() to build the tree top-down. ( Icbdc2 )

  • Added dismissOnBackPress and dismissOnClickOutside properties to AndroidDialogProperties. These allow configuring when the dialog's onDismissRequest lambda will be invoked. ( If5e17 )

  • Added painterResource API to handle opaquely loading Painter objects from either rasterized asset formats (like PNGs) or VectorDrawables. Consumers no longer have to determine the type of asset in advance and can call this method to get a Painter object to use in Image composables or painter modifiers. ( I2c703 , b/173818471 )

  • Added Modifier.clearAndSetSemantics to clear descendants' semantics and set new ones. ( I277ca )

  • Moved ContentDrawScope to ui-graphics module to be with DrawScope. ( Iee043 , b/173832789 )

  • Introduced PathEffect graphics API to provide different patterns to stroked shapes. Deprecated usage of NativePathEffect in favor of expect/actual implementation of PathEffect. ( I5e976 , b/171072166 )

  • Added IdlingResource interfaces to Compose, as a Compose supported variant of Espresso's idling resources. They can be registered and unregistered through the ComposeTestRule ( I433f3 )

  • Removed global (un)registration of ComposeIdlingResource and global (un)registration of clocks into ComposeIdlingResource ( I32660 )

رفع اشکالات

  • Lambdas in offset modifiers now return IntOffset rather than Float. ( Ic9ee5 , b/174137212 , b/174146755 )

  • Removed SlotTable, SlotReader and SlotWriter from the public API. These were marked as InternalComposeAPI previously. Now they are internal to the compose module.

    CompositionData and CompositionGroup were added as a replacement for the ui-tooling API to use to extract composition information. These are public but are not intended for use outside the ui-tooling API as they provide the raw information the ui-tooling API interprets ( I31a9c )

  • Refactored ShaderBrush to lazily create a shader instance when sizing information of the drawing environment is available. This is useful to define gradients that occupy the full drawing bounds of a composable at composition time, without having to implement custom DrawModifier implementations.

    Deprecated gradient function constructor APIs in favor of factory methods on a Gradient object. ( I511fc , b/173066799 )

  • Deprecate LazyColumnFor, LazyRowFor, LazyColumnForIndexed and LazyRowForIndexed. Use LazyColumn and LazyRow instead ( I5b48c )

  • Deprecated BuildCompat.isAtLeastR ( Idb37e )

  • Added buildAnnotatedString factory function in order to build an AnnotatedString. Deprecated annotatedString builder function. ( Idfe0b )

  • Updated Modifier.drawWithCache API to expose ContentDrawScope as a receiver scope instead of DrawScope in order to provide implementations the ability to re-order drawing commands. This is useful for blending/ tinting use cases in which content pixels must be rendered first in order for the corresponding blend mode algorithm to be applied properly. ( Ie7ec8 )
  • Move SimpleContainer into PopupTestUtils.kt ( I78c57 )
  • ConsumedData is no longer a data class. See https://android-review.googlesource.com/c/platform/frameworks/support/+/1455219 for details ( I1737f )

    • ( Iffcbb , b/170434992 )

رفع اشکالات

  • API lint check for MissingGetterMatchingBuilder is enabled for androidx ( I4bbea , b/138602561 )

  • Remove getLineEllipsisOffset/getLineEllipsisCount. Use getLineVisibleEnd/getLineEnd/isLineEllipsized instead. ( I85aa2 )
  • Add some Marks/Annotations for best practice reason. ( I66b20 )

    21. Updated VertexMode enum to be PascalCase
    22. Updated DrawScope selectPaint method to conditionally overwrite stroke parameters on the paint if they have changed
    23. Updated Size to add destructuring API, rename UnspecifiedSize to Unspecified and removed unused methods
  • Updated compose BlendMode API consumption to properly map between Android framework BlendModes and PorterDuff modes depending on API level. Introduced BlendMode#isSupported API to act as a capability query to determine if the BlendMode is supported on the device before it is used. ( I0ef42 )
  • LazyItemScope was added for itemContent param of Lazy lists. It provides modifiers to fill the parent max size which solves the use case when the item should fill the viewport and the regular Modifier.fillMaxSize() doesn't work as the item is measured with infinity constraints. ( Ibd3b2 , b/162248854 )
  • Removed SemanticsNodeInteraction.performPartialGesture . Use SemanticsNodeInteraction.performGesture instead. ( Id9b62 )
  • LazyColumnItems was renamed to LazyColumnFor . LazyRowItems was renamed to LazyRowFor ( I84f84 )

    • اندازه
    • شعاع
    • حرکت

    • TransformOrigin

    • Deprecated Size.copy companion object method favor of instance copy method ( Ife290 , b/159905651 )

  • Popups, Dialogs and Menus are now inheriting the contextual MaterialTheme ( Ia3665 , b/156527485 )

  • TextDirection is renamed as ResolvedTextDirection ( I3ff38 )

  • Removed layout direction parameter from the measure block of the Layout() function. Layout direction is however available inside the callback through the measure scope object ( Ic7d9d )

  • Refactor SelectionHandles for reusing. ( I420e0 )

  • Clickable was removed. Use Modifier.clickable ( I84bdf )

  • TestTag and Semantics have been deleted. Use Modifier.testTag and Modifier.semantics instead ( I15ff0 , b/158841414 )

  • Prior to this change, the compose compiler plugin would non-trivially intercept calls to constructors inside of a @Composable function if there was an ( I5205a , b/158123804 )

  • Modifier.tag was renamed to Modifier.layoutId, to avoid confusion with Modifier.testTag. ( I995f0 )

  • Alignment line Int positions returned from Placeable#get(AlignmentLine) are now non-null. If the queried alignment line is missing, AlignmentLine.Unspecified will be returned. ( I896c5 , b/158134875 )

  • The AndroidView composable was added a modifier parameter. ( I48a88 , b/158746303 )

  • Semantics() is deprecated. Use Modifier.semantics() instead. ( I72407 , b/158841414 )

  • Add viewModel() composable which allows to create or get already created ViewModel similarly to how it works in Activity or Fragment ( I5fdd1 )

  • Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. ( Ib7b44 )

  • In order to consolidate the number of classes used to represent sizing information, standardize on usage of the Size class instead of PxSize. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent width and height represented as floats. ( Ic0191 )

  • In order to consolidate the number of classes used to represent positioning information, standardize on usage of the Offset class instead of PxPosition. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent x and y offsets represented as floats. ( I3ad98 )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters. Deleted Px class in its entirety ( I3ff33 )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I086f4 )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( Id3434 )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I97a5a )

  • TestTag is now deprecated. Use Modifier.testTag instead. ( If5110 , b/157173105 )

  • The default, no-op, implementation of ParentDataModifier#modifyParentData has been removed - it was equivalent to not implementing the interface in the first place. ( I0deaa )

  • Previously deprecated ScaleFit as removed. Use ContentScale instead. ( Ifbc5b )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I19d02 )

  • Added the DropdownMenu component in ui-material, a Material Design menu implementation. ( I9bb3d )

  • Removed deprecated LayoutTag(), please use Modifier.tag() instead. Removed deprecated Modifier.matchParent(), please use Modifier.matchParentSize() instead. ( If8044 )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I57bff )

  • Modifier.semantics has been undeprecated to allow usages for high level components. ( I4cfdc )

  • Consolidated CanvasScope implementations so there is now just DrawScope and ContentDrawScope Renamed CanvasScope to DrawScope. Updated DrawScope to implement Density interface and provide LayoutDirection Deleted DrawScope subclass in ContentDrawScope Painter and PainterModifier have been updated to no longer maintain an RTL property themselves as DrawScope provides this already without manually providing it ( I1798e )

  • DoubleTapGestureFilter now disambiguates SingleTapGestureFilter across the tree. ( If92b1 )

  • Updated Alignment API and added support for absolute alignment (which does not auto-mirror in Rtl context) ( I38cd3 )

  • DrawLayer modifiers api has been changed: outlineShape renamed to shape and has the RectangleShape default value and now non-nullable; clipToOutline renamed to clip; clipToBounds removed as it is the same as clip == true with RectangleShape ( I7ef11 , b/155075735 )

  • Updated higher level compose APIs that expose a Canvas to expose CanvasScope instead. This removes the need for consumers to maintain their own Paint objects. For consumers that still require access to a Canvas they can use the drawCanvas extension method which provides a callback to issue drawing commands with the underlying Canvas. ( I80afd )

  • WithConstraints trailing lambda API has been changed. Now instead of two params it has a receiver scope which in addition to constraints and layoutDirection provides minWidth, maxWidth, minHeight and maxHeight properties in Dp ( I91b9a , b/149979702 )

  • Renamed LayoutModifier2 to LayoutModifier. ( Id29f3 )

  • Removed deprecated LayoutModifier interface. ( I2a9d6 )

  • Intrinsic measurements functions in Layout and LayoutModifier2 have an IntrinsicMeasureScope receiver now which provides intrinsics query API with implicitly propagated layout direction. ( Id9945 )

  • Layout and LayoutModifier children can be measured with a different layout direction. ( Ibd731 )

  • New Modifier.zIndex() is added to control the drawing order of the children within the same parent layout. elevation property on DrawLayerModifier is renamed to shadowElevation and doesn't control the drawing order anymore. The params order fo DrawShadow is changed: elevation is now the first one and the shape is the second one with a RectangleShape default. ( I20150 , b/152417501 )

  • Removed onSizeChange and onPositionChange in Owner. ( I5c718 )

  • Added Constraints2, a copy of Constraints that does only supports Int connstraints values rather than IntPx. IntPx will be removed and all integer constraints will be assumed to be pixels like Android.

    • Added IntSize as well, which will eventually replace IntPxSize. ( I4b43a )

  • Made Alignment instantiable with arbitrary values. Added 1D Alignments. ( Ia0c05 )

  • alignToSiblings now accepts a Measured instead of Placeable. ( I5788d )

  • ( I45f09 , b/152842521 )

    • Renamed ScaleFit to ContentScale
    • Moved ContentScale from ui-graphics to ui-core module to live in the same module as the Alignment API.
    • Renamed FillMaxDimension to Crop
    • Renamed FillMinDimension to Fit
    • Renamed Fit to Inside to better match
    • ImageView.ScaleType equivalents
    • Added documentation indicating that the combination of Crop and Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_CROP and Fit used with Alignment.Center achieves the same result as ImageView.ScaleType.FIT_CENTER Inside used with Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_INSIDE

  • Rtl support for draw modifiers. ( I0aaf9 )

  • Released API for inflating Android Views from XML. See ViewInCompose demo for more details. ( I42916 )

  • Improve DrawModifier API:

    • Made the receiver scope for draw() ContentDrawScope
    • Removed all parameters on draw()
    • DrawScope has same interface as former CanvasScope
    • ContentDrawScope has drawContent() method ( Ibaced , b/152919067 )

  • Added positionInParent and boundsInParent for LayoutCoordinates. ( Icacdd , b/152735784 )

  • DrawLayerModifier and drawLayer() now default clipToBounds and clipToOutline to false. ( I0eb8b , b/152810850 )

  • Renamed LayoutResult to MeasureResult. ( Id8c68 )

  • Added LayoutModifier2, a new API for defining layout modifiers; deprecated LayoutModifier ( If32ac )

  • Replaced Modifier plus operator with factory extension functions ( I225e4 )

  • Added translationX/Y properties to support offseting the display list of drawing commands for a given Layer. This is useful to move content in response to animations or touch events. ( I8641c )

  • Added pivotX, pivotY parameters to Layer APIs to support rotation and scaling around a particular point on a layer ( Icf7c3 )

  • Add OnPositionedModifier and OnChildPositionedModifier to replace OnPositioned and OnChildPositioned composable functions. ( I2ec8f )

  • Added LayerModifier, a modifier that allows adding a RenderNode for a Layout. It allows setting clipping, opacity, rotation, scaling, and shadows. This will replace RepaintBoundary. ( I7100d , b/150774014 )

  • Made the layout direction be propagated from parent layout node to children. Added layout direction modifier. ( I3d955 )

  • Stack component supports right-to-left directionality ( Ic9e00 )

  • Initial support for Rtl in Compose layout ( Ia5519 )

  • Density and DensityScope were merged into one interface. Instead of ambientDensity() you can now use DensityAmbient.current. Instead of withDensity(density) just with(density) ( I11cb1 )

  • Changed LayoutCoordinates to make providedAlignmentLines a Set instead of a Map and have LayoutCoordinates implement the get() operator instead for retrieving a value. This makes it easier for modifiers to modify one or more value of the set without creating a new collection for each modifier. ( I0245a )

  • LayoutCoordinates no longer has a position property. The position property does not make sense when considering LayoutModifiers, rotation, or scaling. Instead, developers should use parentCoordinates and childToLocal() to calculate the transform from one LayoutCoordinate to another.

    LayoutCoordinates uses IntPxSize for the size property instead of PxSize. Layouts use integer pixel sizes for layouts, so all layout sizes should use integers and not floating point values. ( I9367b )

  • Improvements to the API surface of Constraints ( I0fd15 )

  • Created CanvasScope API that wraps a Canvas object to expose a stateless, declarative drawing API surface. Transformations are contained within their own receiver scope and sizing information is also scoped to corresponding inset bounds. It does not require a consumer to maintain its own Paint state object for configuring drawing operations.

    • Added CanvasScopeSample as well as updated the demo app to include a declarative graphics demo ( Ifd86d )

  • Removed unused MaskFilter API as it has limited usage and is not optimized for hardware acceleration in most use cases ( I54f76 )

  • RectangleShape moved from androidx.ui.foundation.shape.* to androidx.ui.graphics.* ( Ia74d5 , b/154507984 )

  • Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null ( Iabaa7 )

  • Introduce additional optional rect parameter to ImagePainter to support drawing a subsection of underlying ImageAsset ( I0ea9e )

  • Added Unset Color to represent an unset value without boxing Colors. ( If901a )

  • Added Canvas.rotate and Canvas.scale extension methods to consume optional pivot coordinates for transformations. These default to the top left corner of the current canvas translation.

    Also moved Canvas.rotateRad to be an extension method for consistency ( Ibaca6 )

  • Created PixelMap API to support querying pixel information from an ImageAsset. ( I69ad6 )

  • Renamed toFrameworkRect/toFrameworkRectF to toAndroidRect/toAndroidRectF to match naming convention for object conversions between compose and the Android framework APIs they are built on top of. Also updated docs on these APIs ( I86337 )

  • Added VectorPainter API to replace existing subcomposition API for vector graphics. Result of subcomposition is a VectorPainter object instead of a DrawModifier. Deprecated previous DrawVector composables in favor of VectorPainter.

    Renamed Image(Painter) API to PaintBox(Painter) Created Vector composable that behaves like the Image composable except with a VectorAsset instead of an ImageAsset ( I9af9a , b/149030271 )

  • Renamed Image to ImageAsset to better differentiate the difference between the Image data and the upcoming Image composable used to participate in layout and draw content. _Body:Created extension method on android.graphics.Bitmap, Bitmap.asImageAsset(), to create an instance of an ImageAsset useful for combining traditional Android application development with the compose framework ( Id5bbd )

  • Added TextDirection.Content ( I48f36 )

  • Added TextDecoration.plus operator ( I0ad1a )

  • Force is removed from TextDirectionAlgorithm enum values ( Icc944 )

  • TextDirectionAlgorithm is renamed as TextDirection ( I75ce8 )

  • Implements LongPressAndDrag for TextField Selection. ( I17919 )

  • Added AnnotatedString.getStringAnnotations that returns all annotations within the range. ( I1fa00 )

  • Changed the package name for Locale and LocaleList from androidx.ui.text to androidx.ui.intl ( I8132c )

  • TextField's cursor has a blinking animation ( Id10a7 )

  • API change: AnnotatedString(builder: Builder) is renamed to annotatedString(builder: Builder). ( Ia6377 )

  • API change: AnnotatedString.Item is renamed to AnnotatedString.Range. ( I2d44d )

  • Rename AnnotatedString.Builder.addAnnotationString to addStringAnnotation. ( I5059e )

  • Now it is possible to hide/show software keyboard by using SoftwareKeyboardController which is delivered by onTextInputStarted callback ( I8dc44 , b/151860051 )

  • Added plus operator for (Text/Paragraph/Span)Style which delegates to merge() function. ( Ia1add )

  • FontWeight.lerp does not snap anymore. It is still a data class. ( I521c2 )

  • FontWeight constructor is now public, it is not data class anymore. ( Id6b1f )

  • Add getLineStart, getLineEnd, getEllipsisOffset and getEllipsisCount to TextLayoutResult ( Ibc801 )

  • ui-text module is renamed as ui-text-core ( I57dec )

  • Removed unused Size class as there is a duplicate Size class in the ui-geometry module that is being consumed. ( I1b602 )

  • Added AdapterList, a scrolling list component that only composes and lays out the visible items. Currently known issues include that it is vertical-only and does not fully handle all cases of changes to its children. ( Ib351b )

  • Add paddings, border, shape and background param to Box ( I05027 , b/148147281 )

رفع اشکالات

  • onFocusChange callback in text fields renamed to onFocusChanged ( Ida4a1 )
  • VerticalScroller and HoriziontalScroller have been deprecated. Use ScrollableColumn and ScrollableRow for build-in experience with Column/Row behaviour and parameters, or Modifier.verticalScroll and Modifier.horizontalScroll on your own element. Similarly, ScrollerPosition has been deprecated in favor of ScrollState' ( I400ce , b/157225838 , b/149460415 , b/154105299 )
  • runOnIdleCompose renamed to runOnIdle ( I83607 )
  • Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. ( I7f164 )
  • Compose UI can now be composed inside ViewGroups without requiring a new composition. See ViewInteropDemo for an example. ( I9ab0b , b/160455080 )
  • Added sortWith and removeRange to MutableVector ( Icccf7 )
  • Implement Drag Selection Handles to change selection for TextField. ( I27032 )
  • Removed Shader inline class that wrapped the NativeShader expect class Renamed NativeShader to Shader. The wrapped Shader inline class did not add anything valuable to the API surface and was an inline class, so use the NativeShader class directly. ( I25e4d )

  • Refactored PainterModifier to no longer provide scaling based on the given constraints and ContentScale parameter. Implementations of Painter are to scale their drawing content themselves based on the given size of the DrawScope they are drawing into.

    Fixed issue where VectorPainter's cache bitmap was sized to its default size instead of the given size to draw into.

    Updated ImagePainter to scale its content instead of relying on PainterModifier to do so on its behalf. ( I6ba90 )

  • add top-level withFrameNanos function for animation timing ( Ie34c5 )

  • @Untracked annotation has been deprecated. Replace with @ComposableContract(tracked=false) ( Id211e )

  • androidx.ui.foundation.TextFieldValue and androidx.ui.input.EditorValue is deprecated. TextField, FilledTextField and CoreTextField composables that uses that type is also deprecated. Please use androidx.ui.input.TextFieldValue instead ( I4066d , b/155211005 )

  • Fixed issue where pointer input dispatch would cause a crash if PointerInputFilters were removed via subcomposition during disptach. This is now fixed. ( I1f48b , b/157998762 )

  • Fixed issue where pointer input dispatch would cause a crash if PointerInputFilters were removed via subcomposition during disptach. This is now fixed. ( Iab398 , b/157998762 )

  • Refactored Radius class to be an inline class. Removed companion creation methods in favor of function constructor with default parameter to have the radius along the y-axis match that of the mandatory x-axis radius parameter.

    Updated DrawScope.drawRoundRect to consume a single Radius parameter instead of 2 separate float values for the radius along the x and y axis ( I46d1b )

  • The Recompose composable is no longer a useful abstraction. Most recomposition should happen as a result of MutableState assignments. For anything beyond that, it is recommended that you use the invalidate function to trigger a recomposition of the current scope. ( Ifc992 )

  • Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( Iede0b )

  • Changes the code generation strategy of Compose's compiler. Prior to the change, the compose compiler would transform calls to composable functions. With this change, we now transform the body of a composable function and leave the callsite unaltered (mostly).

    This means that most of the logic communicating with the compose runtime happens at the start of the function body, instead of at the callsite.

    This should be a source-compatible change for all usage of compose. Most users of compose should not have to update any code as a result of this change.

    In order to support this work, the JVM signature of all composable functions has changed. A Composable function accepting a single parameter is transformed into a function accepting 3 parameters, the additional parameters are the Composer, a 'key' integer. a bitmask integer used to propagate metadata through calls.

    Compose now also transforms default arguments to a composable function. It does this without introducing an additional synthetic default overload of the function itself, so this change will result in fewer functions being defined.

    Known intentional behavioral changes resulting from this:

    1. Some calls will skip where they wouldn't have previously
    2. Composable expressions in default argument expressions are now correctly subscribed to and handled

    This work included some optimizations: 1. The result of comparisons of parameters are propagated through the call graph to other composable functions. This will result in fewer comparisons at runtime, reduces the slot table size, as well as more skipping of composable functions that were previously not skipped 2. Paremeters which are determined to be “static” at compile time are no longer compared or stored in the runtime. This reduces the number of comparisons and reduces slot table size. 3. Control flow structure of the body of functions is used to minimize the number of groups that are generated. This reduces slot table size and results in less work for the runtime 4. Unused dispatch and receiver parameters to functions are not included in determining skippability of the function if they are not used inside of the body of the function.

    Most breaking changes were for APIs that the compiler targets directly, and typical use of compose will not be affected: 1. Composer::startExpr was removed 2. Composer::endExpr was removed 3. Composer::call was deprecated 4. The non-varargs overloads of key have been removed. Use the vararg version going forward. 5. The Pivotal annotation was deprecated. Use key as a replacement. 6. ScopeUpdateScope::updateScope was changed to expect a Function3 instead of Function1 7. restartableFunction and restartableFunctionN were updated to include additional compile time parameters ( I60756 , b/143464846 )

  • Removed deprecated LayoutAlign modifiers. ( I10877 )

  • Removed RepaintBoundary in favor of DrawLayerModifier ( I00aa4 )

  • Button, FloatingActionButton and Clickable now have a separate enabled param. Some of the params on Button were renamed or reordered. ( I54b5a )

  • Replaced ButtonStyle with distinct functions and removed text (string) overload. See updated samples for usage information. ( If63ab , b/146478620 , b/146482131 )

  • Breaking changes to the ambients API. See log and Ambient<T> documentation for details ( I4c7ee , b/143769776 )

  • Changed the behavior of default TextDirection to be determined by LayoutDirection. ie If LayoutDirection is RTL, default TextDirection will be RTL. Previously it was TextDirection.ContentOrLtr/Rtl ( I4e803 )

  • Bug fix: When font weight and font style are nested on an AnnotatedString, text is not rendered correctly. ( I77a9d )

  • Adds commonly used parameters to Text(). If you are currently creating a local text style to pass a small number of these parameters, such as Text(style = TextStyle(textAlign = TextAlign.Center)), you can now just provide the parameters directly: Text(textAlign = TextAlign.Center) ( I82768 )

  • ui-android-text module is renamed as ui-text-android ( I68cbe )
