29 مه 2024

androidx.compose.ui:ui-*:1.7.0-beta02 منتشر شد. نسخه 1.7.0-beta02 حاوی این تعهدات است.

تغییرات API

• تغییر نام SemanticsProperties.Editable به IsEditable و تغییر SemanticsPropertyReceiver.editable به val isEditable . این ویژگی اکنون یک بولی است و همیشه توسط فیلدهای متنی مشخص می شود. ( I8acd8 )
• تغییر نام پارامتر معیار دسترسی. ( I3d440 )
• API به روز شده برای استایل دادن به پیوندها: TextLinkStyles اکنون بخشی از سازنده LinkAnnotation و روش AnnotatedString.fromHtml ( I90b2b ) است. همچنین TextDefaults از مطالب حذف کرد ( I5477b )

رفع اشکال

• تغییر نام LayoutCoordinates.introducesFrameOfReference به LayoutCoordinates.introducesMotionFrameOfReference برای انعکاس بهتر هدف آن. تغییر نام تابع مرتبط برای محاسبه مختصات بر اساس آن پرچم. ( I3a330 )

• AnnotatedString.hasEqualsAnnotations اکنون hasEqualAnnotations است ( I685c0 )
• API را برای دریافت پیوندهای مضمون مواد در متن به روز کرد. به طور خاص، روش‌ها را از TextDefaults برای ساخت LinkAnnotations با مضمون حذف کرد و HTML را با پیوندهای مضمون تجزیه کرد. در عوض، یک کلاس TextLinkStyles اضافه کرد که اجازه می دهد تا به پیوندها به عنوان یک پارامتر به Text composable استایل دهید. ( I31b93 )

رفع اشکال

• موارد استفاده اضافی را هنگام افزودن پویا اصلاح کننده های ورودی اشاره گر در طول رویدادهای 63e1504 برطرف می کند.

نسخه 1.7.0-alpha08

1 مه 2024

androidx.compose.ui:ui-*:1.7.0-alpha08 منتشر شد. نسخه 1.7.0-alpha08 حاوی این commit ها است.

تغییرات API

• پشتیبانی از پیاده سازی شکل های قابل تغییر را اضافه می کند. Shape#createOutline اکنون در داخل لایه‌های گرافیکی مشاهده می‌شود، بنابراین خواندن مقادیر حالت در داخل باعث بی‌اعتباری زمانی می‌شود که حالت تغییر می‌کند و امکان ایجاد انیمیشن‌های شکل با عملکرد بیشتر را فراهم می‌کند. ( Id1629 , b/326070216 )
• isPositionedByParentWithDirectManipulation به introducesFrameOfReference تغییر نام داد. توجه داشته باشید که اکنون اثر معکوس دارد، به این معنی که به طور پیش‌فرض، اکثر LayoutCoordinates یک چارچوب مرجع معرفی می‌کنند، و تنها زمانی که تحت دستکاری مستقیم قرار می‌گیرد، ویژگی نادرست خواهد بود. برای جست‌وجوی موقعیت فقط با آنهایی که چارچوب مرجع را معرفی می‌کنند، از positionInLocalFrameOfReference(...) استفاده کنید. یا positionInLocalLookaheadFrameOfReference از LookaheadScope . ( Ifc5f7 )
• API های LookaheadScope پایدار شده اند ( I21507 )
• بر اساس بازخورد شورای API، اقدام lambda را برای getScrollViewportLength تغییر دهید. ( IBC74a )
• به‌روزرسانی شده GraphicsLayer APIهای کلی را برای مصرف پارامترهای float به جای int. مقادیر نگهبان UnsetOffset/UnsetSize IntSize به نفع ثابت های نامشخص موجود در کلاس های درون خطی Offset و Size مبتنی بر شناور حذف شد ( I2fb03 , b/333863462 )
• هنگام تزریق ورودی ماوس در طول آزمایش‌ها، MouseInjectionScope.click() , MouseInjectionScope.doubleClick() , MouseInjectionScope.tripleClick() , MouseInjectionScope.longClick() اکنون یک button: MouseButton تا آنها را به طور جهانی کاربردی تر کند. مقدار پیش فرض MouseButton.Primary برای همه متدها است. ( I31a23 , b/190493367 , b/261439695 )
• تغییر نام onClicked به onClick در داخل LinkInteractionListener . ( Iaa35c )
• تغییر نام TextInclusionStrategy.isInside به isIncluded . نوع برگشتی Paragraph/MultiParagraph#getRangeForRect() را غیر قابل پوچ کنید. ( I51f26 )

رفع اشکال

• ضبط اسکرین شات طولانی برای محفظه های اسکرول با reverseScrolling=true ثابت شد. ( I7c59c )

مشارکت خارجی

• پشتیبانی برای واکشی از قبل موارد در LazyLists تو در تو (به عنوان مثال LazyColumn که LazyRows تودرتو را ارائه می دهد) اضافه شده است. انتظار می رود این تغییر افت فریم را در حین پیمایش برای این LazyLists کاهش دهد. پیش‌فرض پیاده‌سازی، واکشی دو مورد اول تودرتو است، اما این رفتار را می‌توان با LazyLayoutPrefetchStrategy(nestedPrefetchItemCount) و LazyListPrefetchStrategy#onNestedPrefetch جدید کنترل کرد. ( I51952 )

نسخه 1.7.0-alpha07

17 آوریل 2024

androidx.compose.ui:ui-*:1.7.0-alpha07 منتشر شد. نسخه 1.7.0-alpha07 حاوی این تعهدات است.

تغییرات API

• ClickableText به عنوان منسوخ علامت گذاری شده است. برای افزودن پیوند به متن، یک AnnotatedString با یک LinkAnnotation مربوط به پیوند خود ایجاد کنید و این AnnotatedString به Text composable ارسال کنید. ( I34d4b , b/323346994 )
• ViewConfiguration.HandwritingGestureLineMargin را برای حرکات دست خط معرفی کنید. پشتیبانی از ژست JoinOrSplit برای BasicTextField ( Ie6e13 , b/325660505 )
• FocusProperties.enter و FocusProperties.exit دیگر آزمایشی نیستند. FocusDirection.Enter و FocusDirection.Exit دیگر آزمایشی نیستند. FocusRequester.Cancel دیگر آزمایشی نیست ( I461a1 , b/261564106 )
• هنگام جستجو در مختصات Layout، اکنون می‌توانید از آرگومان excludeDirectManipulationOffset برای حذف افست مجموعه‌ای از Layouts والدین که فرزندان خود را با استفاده از Placeable.PlacementScope.withDirectManipulationPlacement قرار داده‌اند، استفاده کنید. به همین ترتیب، Layout که موقعیت فرزندان خود را مرتباً تغییر می‌دهد، اکنون می‌تواند آنها را با استفاده از withDirectManipulationPlacement (مانند Scroll که به طور پیش‌فرض پیاده‌سازی شده است) قرار دهد. این به انیمیشن‌های مبتنی بر approachLayout کمک می‌کند تا بصری‌تر باشند، و اکنون این فرصت را دارند که متمایز کنند چه افستی باید متحرک شود و چه چیزی مستقیماً هنگام تصمیم‌گیری برای متحرک کردن رویکرد خود اعمال شود. ( I60ec7 )
• پرچم ویژگی برای اسکرین شات های طولانی حذف شده است. ( I28648 , b/329128246 )
• LazyColumn اکنون هدرهای چسبنده را به درستی در اسکرین شات های طولانی ارائه می کند. ( I8d239 , b/329296635 )
• منابع NestedScroll Drag and Fling با UserInput و SideEffect جایگزین می شوند تا با تعریف گسترده این منابع که اکنون شامل انیمیشن ها (Side Effect) و Mouse Wheel and Keyboard ( UserInput ) می شوند، سازگار شوند. ( I40579 )
• ApproachLayoutModifierNode و Modifier.approachLayout اکنون پایدار هستند، با isMeasurementApproachInProgress() و isPlacementApproachInProgress() جدید به ترتیب جایگزین isMeasurementApproachComplete() قدیمی و isPlacementApproachComplete() .
• اصلاح کننده منسوخ intermediateLayout حذف شد. ( I3e91c )
• نام GraphicsLayer#buildLayer را تغییر دهید تا ضبط شود تا روش‌های start/endRecording APIهای پشتیبانی‌شده Displaylist مانند RenderNode و Picture را منعکس کند.
• rememberGraphicsLayer برای استفاده از rememberObserver به روز شد. ( I312c1 , b/288494724 , b/330758155 )
• UrlAnnotation منسوخ شده است، به جای آن LinkAnnotation.Url استفاده کنید. اگر از موضوع‌بندی Material استفاده می‌کنید، از شی TextDefaults برای ایجاد حاشیه‌نویسی با مضمون Material روی آن استفاده کنید ( I8d180 , b/323346545 )
• پیوندهای متنی علاوه بر استایل معمولی، گزینه استایل حالت فشرده را نیز دریافت کردند، شناور و فوکوس شدند ( I5f864 ، b/139312671 )
• String.parseAsHtml به AnnotatedString.Companion.fromHtml تغییر نام داد. ( I43dcd )
• آرگومان های سبک ( linkStyle ، focusedLinkStyle ، hoveredLinkStyle ) و شنونده تعامل پیوند به روش parseAsHtml اضافه شده است. هنگامی که رشته برچسب‌گذاری شده HTML را با تگ‌های <a> تجزیه می‌کند، این روش برای هر تگ یک LinkAnnotation.Url ایجاد می‌کند و اشیاء استایل و شنونده تعامل پیوند را به هر حاشیه‌نویسی ارسال می‌کند. ( I7c977 )
• اکنون LinkAnnotation آرگومان های استایل مبتنی بر حالت و LinkInteractionListener را می گیرد. برای دریافت هایپرلینک، این حاشیه نویسی را به AnnotatedString اضافه کنید. با عبور از focusedState و/یا hoveredState می توانید configuration بصری پیوندها را زمانی که فوکوس شده و/یا شناور هستند تعریف کنید. ( I81ce4 , b/139312671 )
• ImeOptions.hintLocales دیگر پوچ نیست. اگر می‌خواهید یک لیست محلی خالی را ارسال کنید، لطفاً از LocaleList.Empty استفاده کنید. ( IC5bc4 )

رفع اشکال

• داده‌های رویداد ورودی تاریخی بد/فاسد را با مهربانی مدیریت می‌کند (داده‌های آفست بد را نادیده می‌گیرد).
• هنگامی که یک اصلاح‌کننده ورودی اشاره‌گر به‌صورت پویا قبل از اصلاح‌کننده ورودی اشاره‌گر دیگر در جریان یک جریان رویداد ورودی اشاره‌گر فعال اضافه می‌شود، رویدادهای غیرمنتظره اشاره‌گر را برطرف می‌کند (به عنوان مثال، بین ورودی شناور و خروجی نشانگر [موس/قلم]).

نسخه 1.7.0-alpha06

3 آوریل 2024

androidx.compose.ui:ui-*:1.7.0-alpha06 منتشر شد. نسخه 1.7.0-alpha06 حاوی این تعهدات است.

ویژگی های جدید

• اضافه شدن متد parseAsHtml برای رشته های استایل دار: امکان تبدیل رشته ای که با تگ های HTML مشخص شده است را به AnnotatedString می دهد. توجه داشته باشید که همه تگ‌ها پشتیبانی نمی‌شوند، برای مثال شما هنوز نمی‌توانید لیست‌های گلوله را نمایش دهید. ( I84d3d , I30626 , b/139326648 )
• با استفاده از API رسمی Android ( ScrollCaptureCallback ) از اسکرین‌شات‌های طولانی در محفظه‌های پیمایش Compose پشتیبانی آزمایشی اجرا کرد. این ویژگی آزمایشی است و ممکن است در حال حاضر همه موارد را به درستی مدیریت نکند. به همین دلیل در حال حاضر به طور پیش فرض غیرفعال است. برای شرکت کردن، پرچم ComposeFeatureFlag_LongScreenshotsEnabled را روی true تنظیم کنید. ( I2b055 , b/329296471 )

تغییرات API

• fun ClipEntry.getMetadata() به val ClipEntry.clipMetadata تغییر کرده است. ( I50155 )
• توابع ClipboardManager.getClipMetadata و ClipboardManager.hasClip حذف شدند. لطفاً از clipEntry.getMetadata() برای خواندن فراداده ورودی کلیپ فعلی استفاده کنید. همچنین نتیجه ClipboardManager.getClip را در صورت تهی بودن یا نبودن آن بررسی کنید تا متوجه شوید که Clipboard یک کلیپ فعلی دارد یا خیر. ( I50498 )
• اکنون می توانید اشیاء GraphicsLayer را به توابع placeable.placeWithLayer() ( I1b22f ) منتقل کنید.
• ClipboardManager.setClip اکنون null را می‌پذیرد تا بتواند Clipboard را پاک کند. ( I7d2e9 )
• شناسه‌های منبع اضافه شده برای کمک به پنهان کردن نماها که به عنوان جزئیات پیاده‌سازی در ابزار ساخت استفاده می‌شوند ( I99531 )
• روش تعلیق GraphicsLayer#toImageBitmap برای پشتیبانی از رندر کردن محتوای یک بیت مپ در GraphicsLayer اضافه شد. این یک عملیات رندر سریع سخت افزاری در سطح API 22+ (شامل) است که بیش از 99٪ از همه دستگاه های Android را پشتیبانی می کند. در Android API سطح 21 این به رندر نرم افزار بازمی گردد. ( I9e114 )
• روش کمکی برای تبدیل Android RectF به ComposeRect ( I39925 , b/325660505 )
• همه پارامترهای KeyboardOptions اکنون به طور پیش فرض دارای یک مقدار نامشخص هستند. روش KeyboardOptions.merge اضافه شد.
• KeyboardOptions.autoCorrect را به autoCorrectEnabled تغییر نام داد و آن را nullable کرد، جایی که null نشان می دهد هیچ مقداری مشخص نشده است. ( Ia8ba0 , b/295951492 )
• نوع BasicTextField(state) و BasicSecureTextField اکنون به جای KeyboardActionHandler از KeyboardActions برای پردازش اقدامات انجام شده توسط صفحه کلید نرم افزار استفاده می کنند. ( I58dda )

نسخه 1.7.0-alpha05

20 مارس 2024

androidx.compose.ui:ui-*:1.7.0-alpha05 منتشر شد. نسخه 1.7.0-alpha05 حاوی این تعهدات است.

ویژگی های جدید

• GraphicsLayer API جدید را برای ثبت دستورات ترسیم در لیست نمایش و همچنین ویژگی های اضافی که بر رندر لیست نمایش تأثیر می گذارد، معرفی کنید. این یک مرز انزوا برای تقسیم یک صحنه پیچیده به قطعات کوچکتر فراهم می کند که می توانند به صورت جداگانه از یکدیگر بدون بازسازی کل صحنه به روز شوند. تبدیل های ایجاد شده به GraphicsLayer را می توان بدون ضبط مجدد لیست نمایش انجام داد. برخلاف Modifier.graphicsLayer ، GraphicsLayer امکان رندر کردن محتوای Composable را در جای دیگری فراهم می‌کند و در موارد استفاده متحرک که انتظار می‌رود محتوا در صحنه‌های مختلف رندر شود، مفید است.

تغییرات API

• GraphicsLayer.draw(Canvas) دیگر یک api عمومی نیست. لطفاً به جای آن از تابع پسوند DrawScope.drawLayer(GraphicsLayer) برای رسم لایه استفاده کنید. ( I7a7c0 )
• restrictedConstraints() را به دو متد تقسیم کنید: fitPrioritizingWidth() و fitPrioritizingHeight() ( I6d7fd )
• مقاله خرد HardwareCanvas برای استفاده از Android L ( I1c3b5 , b/288494724 ) معرفی شد
• چارچوب Compose را به‌روزرسانی کنید تا یک ترکیب GraphicsContext محلی را در کنار به‌روزرسانی پیاده‌سازی‌های Owner، DelegateableNode و drawWithCache Modifier به‌روزرسانی کنید تا دسترسی به GraphicsContext برای دسترسی محدوده‌ای که به طور خودکار نمونه‌های GraphicsLayer را هنگامی که Modifiers پاره می‌شوند، پاکسازی کند. ( I64a2f , b/288494724 )
• InterceptPlatformTextInput را برای کمک به نوشتن تست‌های سطح پایین مرتبط با IME و سایر موارد استفاده سطح پایین IME معرفی کرد. PlatformTextInputTestOverride منسوخ شده است. ( I862ed , b/322680547 )
• تابع پسوند GraphicsLayer.setOutline(Outline) اضافه شد. ( IB81f4 )
• سازنده تابع GraphicsContext را برای ایجاد کارخانه ای برای ایجاد نمونه های GraphicsLayer معرفی کنید ( Ib98d6 , b/288494724 )
• GraphicsLayer API را برای ارائه انعطاف‌پذیری تعریف‌شده توسط توسعه‌دهنده در گرفتن دستورات ترسیمی که می‌توان از آن برای ترسیم در جاهای دیگر استفاده کرد و همچنین جلوه‌های بصری مختلف را در نتیجه نهایی اعمال کرد، ارائه کرد. ( I80245 , b/288494724 )
• Paragraph#getRangeForRect را معرفی کنید که محدوده ای از متن پوشیده شده توسط یک ناحیه مستطیل معین را برمی گرداند. ( Iee516 , b/325660505 )
• لغو آزمایشی BasicText با آرگومان onLinkClicked حذف شد. یک API جایگزین برای پشتیبانی از پیوندها در آینده دنبال خواهد شد. ( I107d5 )

رفع اشکال

• اضافه شده GraphicsLayer تعریف انتظار/واقعی API برای پشتیبانی از ضبط و پخش مجدد دستورات ترسیم با ترکیب اختیاری جلوه های بصری و تبدیل. رابط GraphicsContext را برای داشتن وابستگی های گرافیکی از جمله ایجاد و مدیریت نمونه های GraphicsLayer معرفی کنید. ( I4a8d6 , b/288494724 )
• مشکل interop با جستجوی فوکوس 1 بعدی که در آن فوکوس در داخل ComposeView که در بین نماهای دیگر تعبیه شده بود گیر می کرد، رفع شد. ( I08fd4 )

مشارکت خارجی

• LocalLifecycleOwner از Compose UI به lifecycle-runtime-compose منتقل شد تا API های کمکی مبتنی بر Compose آن بتوانند خارج از Compose UI استفاده شوند. با تشکر از جیک وارتون برای مشارکت. ( I6c41b , b/328263448 )
• ویژگی‌های شناور بایاس را در همه زیرگروه‌های تراز مبتنی بر بایاس به طور مداوم در معرض دید قرار دهید. ( I69f0f , b/328088992 )

نسخه 1.7.0-alpha04

6 مارس 2024

androidx.compose.ui:ui-*:1.7.0-alpha04 منتشر شد. نسخه 1.7.0-alpha04 حاوی این تعهدات است.

تغییرات API

• پشتیبانی از ویژگی دست‌نویس قلم برای BasicTextField2 در دستگاه‌های بعد از Android U. ( I002e4 )
• در این CL ما اقدام معنایی GetScrollViewportLength را اضافه می کنیم تا بتوانیم اطلاعات مربوط به مؤلفه های در حال پیمایش در compose را به سیستم a11y انتقال دهیم. این CL همچنین استفاده از ویژگی مذکور را در فهرست‌های قابل پیمایش بنیاد اعمال می‌کند. ( IC5fa2 )
• FocusRequester.createRefs اکنون پایدار است ( I4d92c , b/261436820 )
• DelegatableNode.requireView() را معرفی کرد تا به گره های اصلاح کننده اجازه دهد تا View فعلی Android را بدون خواندن یک ترکیب محلی دریافت کنند. ( I40768 )
• API جدید Path.reverse() برای معکوس کردن جهت مسیر ( I36348 )
• hintLocales به KeyboardOptions اضافه کرد تا TextFields با قابلیت اشاره به IME با زبان‌های خاص برای از پیش تعیین کردن یک زبان ترجیحی ارائه کند.
• ویژگی platformLocale را از Locale نشان دهید که شی پلتفرم زیرین، به عنوان مثال java.util.Locale را برمی گرداند. ( I921c6 )

نسخه 1.7.0-alpha03

21 فوریه 2024

androidx.compose.ui:ui-*:1.7.0-alpha03 منتشر شد. نسخه 1.7.0-alpha03 حاوی این commit ها است.

تغییرات API

• معرفی ContextualFlowRow و Enhanced FlowRow / Column با MaxLines و Overflow. ما هیجان زده هستیم که پیشرفت‌هایی را در FlowRow و FlowColumn آزمایشی اعلام کنیم که اکنون دارای maxLines و پشتیبانی سرریز است، در کنار اولین ContextualFlowRow و ContextualFlowColumn . این به‌روزرسانی برای ارائه اجزای عملکرد بهینه طراحی شده است، جایی که ContextualFlow* برای تعداد زیادی آیتم با استفاده از پیکربندی کوچک maxLines و پویا +N برای دیدن دکمه‌های بیشتر عالی است، و FlowRow و FlowColumn برای تعداد کمی از موارد، کمتر مناسب است. بیش از 100 مورد مهم: برای حفظ رفتار موجود در FlowRow یا FlowColumn که در آن همه موارد بدون توجه به اینکه آیا با حداکثر محور متقاطع مطابقت دارند یا نه، تشکیل شده‌اند، overflow در طول مقداردهی اولیه روی FlowRowOverflow.Visible یا FlowColumnOverflow.Visible تنظیم کنید. ContextualFlowRowSample و FlowRowSample را برای نمونه هایی از این ویژگی های جدید در عمل کاوش کنید. ( Ib9135 , b/293577082 )
• ویژگی معنایی maxTextLength را اضافه کنید که باید در فیلدهای متنی تنظیم شود که حداکثر تعداد مجاز کاراکترها را فیلتر می کند. ( I24d9f , b/170648072 )
• پوشش Modifier.inspectable منسوخ شده است. این API بیش از حد لازم برای اصلاح‌کننده شما باطل می‌شود، بنابراین استفاده از آن در حال حاضر ممنوع است. اگر می‌خواهند ویژگی‌های اصلاح‌کننده را در معرض ابزار قرار دهند، به توسعه‌دهندگان توصیه می‌شود که متد inspectableProperties() روی ModifierNodeElement پیاده‌سازی کنند. ( Ib3236 )
• سازنده جدید برای PopupProperties که امکان کنترل کامل بر پرچم های WindowManager.LayoutParams را فراهم می کند. ( Ibb33e , b/312485503 )
• DelegatableNode.requireLayoutCoordinates() را به عنوان راهی برای دریافت LayoutCoordinates فعلی Modifier.Node بدون نیاز به نادیده گرفتن onPlaced و ذخیره مختصات در یک ویژگی معرفی کرد. ( Ia8657 )
• DelegatableNode.currentLayoutCoordinates را به عنوان راهی برای بدست آوردن LayoutCoordinates فعلی Modifier.Node بدون نیاز به نادیده گرفتن onPlaced و ذخیره مختصات در یک ویژگی معرفی کرد. ( Iaebaa )
• BasicTextField2 و APIهای مرتبط تحت بسته androidx.compose.foundation.text2 به androidx.compose.foundation.text منتقل می شوند. ( I9f635 )
• یک ApproachLayoutModifierNode API جدید اضافه کرد تا از ایجاد منطق رویکرد سفارشی در یک گره اصلاح کننده صریح پشتیبانی کند. همچنین یک API آزمایشی DeferredTargetAnimation برای انیمیشن‌هایی که هدف آنها در ابتدا ناشناخته است اضافه شده است. ( I60745 )
• API های Path جدید برای پرس و جو جهت یک مسیر و استخراج خطوط از یک Path . ( I63d04 )
• PathHitTest و Path.contains(Offset) اضافه شد تا بررسی شود آیا یک Path دارای نقطه خاصی است یا خیر. ( I3b218 )
• TextLayoutResult اکنون متد getLineBaseline(lineIndex) را نشان می دهد. این اجازه می دهد تا خط پایه یک خط دلخواه متن را علاوه بر ویژگی های راحتی موجود firstBaseline و lastBaseline بخوانید. ( Ide4e8 , b/237428541 )
• روشی برای مقایسه فقط حاشیه نویسی دو AnnotatedStrings اضافه شده است. ( I32659 )

• سازنده PopupProperties که پارامتر usePlatformDefaultWidth را می گیرد دیگر آزمایشی نیست. ( I8f8d2 )
• اضافه‌باری ComposeTestRule.waitUntil اضافه شد که شرح رشته‌ای از شرایط را می‌گیرد تا در پیام مهلت زمانی درج شود. ( I9413e )
• unset() API معنایی جدید برای حذف ویژگی‌های معنایی که در زنجیره اصلاح‌کننده یکسان اضافه شده‌اند. ویژگی جدید معنایی isOpaque . ( I8c583 , b/317966058 , b/246056649 )
• originalEventPosition از روش کپی در API عمومی PointerInputChange حذف شد. ( I7bead )

رفع اشکال

• رفع یک اشکال a11y که به دکمه‌های غیر تب‌ها و غیررادیویی اجازه می‌دهد در صورت انتخاب قابل کلیک باشند. ( I2181c )
• VelocityTracker اکنون راه حلی برای اضافه کردن امتیاز به صورت پیش فرض خواهد داشت. اگر مشکلی وجود داشت، همچنان می‌توانید با تنظیم VelocityTrackerAddPointsFix روی false، این اصلاح را غیرفعال کنید. ( Ib3877 , b/269487059 )
• رفع ناسازگاری باینری معکوس در TextStyle و ParagraphStyle . ( I179f0 , b/320819734 )

مشارکت خارجی

• یک سازنده جدید DialogProperties بدون پارامترهای پلتفرم خاص اضافه شد. ( I45829 )
• یک سازنده PopupProperties جدید بدون پارامترهای پلتفرم خاص اضافه شد. ( I9a038 )

تغییر رفتار: شامل fontpadding اکنون به طور پیش فرض در آهنگسازی نادرست است

includeFontPadding اکنون به طور پیش فرض ( 21d806 ) در آهنگسازی نادرست است.

includeFontPadding یک ویژگی میراث است که کنترل می کند که آیا در بالای خط اول و آخرین خط متن ، برای قرار دادن هر گونه شخصیت هایی که ممکن است در بالا یا زیر خطوط متن گسترش یابد ، شامل بالشتک اضافی در بالای خط اول و آخرین خط متن است.

به روزرسانی این نسخه آهنگسازی چگونه با حذف بالشتک اضافی در بالای خط اول و آخرین خط هر متنی که نمایش داده می شود ، نحوه ارائه همه متون در UI شما را تغییر می دهد.

بسته به نیازهای UI و معیارهای قلم مورد استفاده شما ، تغییرات باید حداقل باشد. با این حال ممکن است با مسدود کننده هایی مانند: - تست های تصویر شکسته. در صورت لزوم UI را برطرف کنید و تصاویر طلایی را بازسازی کنید. - متن کمی نادرست است. در صورت لزوم ، هرگونه بالشتک منفی سفارشی را حذف کرده یا در صورت لزوم بالشتک اضافه کنید.

شما می توانید با استفاده از PlatformTextStyle برای هر متن ، includeFontPadding را شامل شوید:

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

می توانید با includeFontPadding سبک های مواد خود ، برای همه متون خود برای همه متون خود انتخاب کنید. توجه داشته باشید که نام پارامترها بین M2 و M3 متفاوت خواهد بود.

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

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

می توانید اطلاعات بیشتری در مورد includeFontPadding در مستندات توسعه دهنده و این پست وبلاگ پیدا کنید.

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 )

Change Summary

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.

خطر

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 )

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. Refer to KeyInjectionScope for documentation on each function. ( I9f6cd , b/229831515 )
• An experimental OverscrollEffect has been introduced to allow for custom overscroll effects, alongside the Modifier.scrollable overloads that accept it.
• Experimental LocalOverScrollConfiguration has been moved from foundation.gesture to foundation package and renamed to LocalOverscrollConfiguration ( If19fb , b/204650733 )

• 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 )

• 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 )
• The Show Layout Bounds setting will now be applied for composables immediately after toggling it from the quick settings tile, without having to leave and re-enter the activity. ( I843d5 , b/225937688 )
• 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 )

ویژگی های 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). از جانب:

  @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 اشکال

• 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 )

External Contribution

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

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

6 آوریل 2022

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 اشکال

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

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 اشکال

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

External Contribution

• compose-ui: Add ambientShadowColor and spotShadowColor properties to GraphicsLayerScope ( I1ba1a , b/160665122 )

• 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 اشکال

• 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 )

نسخه 1.2.0-alpha04

23 فوریه 2022

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 اشکال

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

• 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 )

• Deprecated AndroidComposeTestRule.AndroidComposeStatement , which was not meant to be in public API and didn't do anything for you anyway. ( Ibc46b )

• Internal generated kt class rename ( Ia0b9e , b/174162090 )

• Removed FontLoadingStrategy.values ( I42a9d , b/174162090 )

• Global font loader is now called FontFamilyResolver . ( I4f773 , b/174162090 )

• Use new font loading system for desktop. ( I9ce5c , b/174162090 )

• FontFamily.Resolver.resolve returns State<Any> ( I4406c , b/174162090 )

رفع اشکال

• TextFields will now be kept above the keyboard when they are focused and the keyboard is shown, when the soft input mode is ADJUST_PAN . ( I8eaeb , b/190539358 , b/192043120 )
• Desktop uses composition local for FontFamily.Resolver
• Desktop FontLoader is deprecated
• New createFontFamilyResolver factory on Desktop ( I6bbbb , b/174162090 )
• The soft keyboard input type no longer flickers when changing focus between text fields. ( I1bf50 , b/187746439 )

نسخه 1.1.0

9 فوریه 2022

androidx.compose.ui:ui-*:1.1.0 is released. نسخه 1.1.0 حاوی این commit ها است.

تغییرات مهم از 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

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 اشکال

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

Version 1.1.0-beta03

17 نوامبر 2021

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 اشکال

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

Version 1.1.0-alpha06

13 اکتبر 2021

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 اشکال

• 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

29 سپتامبر 2021

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 اشکال

• 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 )

نسخه 1.1.0-alpha04

15 سپتامبر 2021

androidx.compose.ui:ui-*:1.1.0-alpha04 is released. نسخه 1.1.0-alpha04 حاوی این commit ها است.

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 اشکال

• 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 )

نسخه 1.1.0-alpha03

1 سپتامبر 2021

androidx.compose.ui:ui-*:1.1.0-alpha03 is released. نسخه 1.1.0-alpha03 حاوی این commit ها است.

ویژگی های 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 اشکال

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

نسخه 1.1.0-alpha02

August 18, 2021

androidx.compose.ui:ui-*:1.1.0-alpha02 is released. نسخه 1.1.0-alpha02 حاوی این commit ها است.

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 )

رفع اشکال

• Updated Vector graphics xml parsing to support ColorStateLists as root color tint properties on VectorDrawables. ( I86915 , b/195668138 )

androidx.compose.ui:ui-*:1.1.0-alpha01 is released. نسخه 1.1.0-alpha01 حاوی این commit ها است.

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 اشکال

• 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 )

ویژگی های جدید

• Split ui-tooling module into ui-tooling and ui-tooling-preview ( Iefa28 , b/190649014 )

تغییرات API

• Removed deprecated experimental FocusManager#moveFocusIn and FocusManager#moveFocusOut ( I227d7 , b/170154986 , b/186567354 , b/168510304 )
• Canvas now supports a contentDescription parameter for accessibility. ( Ib547c )
• useDefaultMaxWidth in PopupProperties was renamed to usePlatformDefaultWidth . ( I05710 )
• Dialogs are now able to use the entire screen width. ( I83929 , b/190810877 )
• Added experimental support for HSV and HSL color representations. ( Id7cf8 , b/180731008 )

تغییرات رفتار

• Compose @Preview now provides a LocalActivityResultRegistryOwner that allows you to preview Composables that use APIs like rememberLauncherForActivityResult() that depend on that owner existing. ( Ib13d1 , b/185693006 )
• Compose @Preview now provides a LocalOnBackPressedDispatcherOwner that allows you to preview Composables that use APIs like BackHandler that depend on that owner existing. ( Ia1c05 , b/185693006 )

رفع اشکال

• Moved InfiniteAnimationPolicy to androidx.compose.ui:ui ( I5eb09 , b/160602714 )
• AnimatedImageVector was temporarily removed in order to change the module structure. ( I41906 , b/160602714 )

Version 1.0.0-beta09

16 ژوئن 2021

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 اشکال

• 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
• androidx.compose.foundation
• androidx.compose.foundation-layout

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.

قوانین چه کار می کنند؟

• 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 چطوری کار میکنه؟

• 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.

• 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 )

رفع اشکال

• 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

18 مه 2021

• FocusDirection enum is replaced by an inline class. ( Ib6d03 , b/187055290 , b/184086802 )
• 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 اشکال

• androidx.compose.ui:ui no longer depends on AppCompat or Fragment. If you are using a ComposeView in your application, and you are using Fragment and/or AppCompat, make sure that you are using AppCompat 1.3+ / Fragment 1.3+ - these versions are needed to correctly set lifecycle and saved state owners required for ComposeView. ( I1d6fa , b/161814404 )

24 فوریه 2021

androidx.compose.ui:ui-*:1.0.0-beta01 is released. نسخه 1.0.0-beta01 حاوی این تعهدات است.

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 )

• Modifier.tapGestureFilter has been removed. Use Modifier.pointerInput { detectTapGestures(...) } instead. ( I266ed , b/175294473 )

• partial consumption was removed from pointer input system. The recommended way of coordinating partial consumtion is Modifier.nestedScroll. ( Ie9c9b )

• Orientation has been moved to foundation package. VelocirtTracker moved from ui.gesture to ui.input.pointer. ( Iff4a8 , b/175294473 )

• imageResource and vectorResource are now extension functions on ImageBitmap and ImageVector companions respectively. load{Image,Vector,Font}Resource functions have been deleted. ( I89130 )

• AnimationClockObservable and subclasses have been removed. AnimatedFloat has been removed. ( Icde52 , b/177457083 )

• Providers has been renamed to CompositionLocalProvider

  • 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.
  • The snapshotFlow function has been moved to the androidx.compose.runtime namespace
  • the merge method of SnapshotMutationPolicy is no longer experimental
  • The @TestOnly top level clearRoots function has been removed. دیگر لازم نیست.
  • keySourceInfoOf and resetSourceInfo functions have been removed. They are no longer necessary.
  • Composer.collectKeySourceInformation has been removed. دیگر لازم نیست.
  • isJoinedKey, joinedKeyLeft, and joinedKeyRight methods have been removed. They are no longer necessary.
  • Various top level APIs have been moved and reorganized into different files. Due to Kotlin's file class semantics, this will break binary compatibility but not source compatibility, so should not be an issue for most users.
  • ( I99b7d , b/177245490 )

• ComponentActivity.setContent() was removed from compose:ui. Use the one from androidx.activity:activity-compose:1.3.0-alpha01 . viewModel() and LocalViewModelStoreOwner were removed from compose:ui. Use the ones from androidx.lifecycle:lifecycle-viewmodel-compose:1.0.0-alpha01 ( I6f36b )

• SnapshotStateObserver is not Experimental anymore ( Id2e6a )

• 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 )

• Removed String.format API refactored usages in various toString methods to not leverage String.format internally. ( Id1290 )

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.
  • Renamed onValueChangeEnd in Slider to onValueChangeFinished and made it nullable.
  • Renamed text parameter in Snackbar to content for consistency.
  • Added contentPadding parameter to DropdownMenuItem to allow customizing the default padding and made content be an extension on RowScope .

• 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 )

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 )

The parentCoordinates property now offers the parent modifier's LayoutCoordintes. This will make for more complete use cases for onSizeChanged() and onGloballyPositioned() ( Idfbfd , b/177926591 )
• tapGestureFilter, doubleTapGestureFilter, longPressGestureFilter and pressIndicaitonGestureFilter have been deprecated. Use Modifier.clickable or Modifier.pointerInput with detectTapGestures function instead. ( I6baf9 , b/175294473 )
• SaveableStateRegistry's unregisterProvider was removed. Instead registerProvider() now returns SaveableStateRegistry.Entry object which you can use to unregister ( Ic4274 , b/178583739 )
• rememberSavedInstanceState() was renamed to rememberSaveable() and moved to androidx.compose.runtime.saveable package. ( I1366e , b/177338004 )
• 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 )
• Removed Recomposer.current(). [Abstract]ComposeView now default to lazily created, window-scoped Recomposers driven by the ViewTreeLifecycleOwner for the window. Recomposition and withFrameNanos-based animation ticks are paused while the host Lifecycle is stopped. ( I38e11 )
• Recomposer.runningRecomposers now offers a global StateFlow of read-only RecomposerInfo for observing ongoing composition state in the process. Prefer this API to Recomposer.current(), which is now deprecated. ( If8ebe )
• Saver, listSaver(), mapSaver(), autoSaver was moved from androidx.compose.runtime.savedinstancestate to androidx.compose.runtime.saveable ( I77fe6 )
• EditCommands accept AnnotatedString. However this is an API only change and multi-style text editing is not implemented yet. ( I4c3ea )
• Uptime and Duration have been removed. ( Ib9bf4 , b/177420019 )
• CompositionData.asTree() and related APIs moved to separate ui-tooling-data module and marked as experimental ( Ic95b8 )
• Parameters on RounderCornerShape, CutCornerShape and CornerBasedShape were renamed from left/right to start/end in order to support the shape's auto mirroring in the rtl direction. AbsoluteRounderCornerShape and AbsoluteCutCornerShape were introduced for the cases when auto-mirroring is not desired. ( I61040 , b/152756983 )

• 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 اشکال

• ComposeViews placed in view hierarchies that are children of another composition now host child compositions of their ancestors ( I92883 )
• Updated compose's imageFromResource API to reuse the resource drawable cache when loading ImageBitmap objects. ( If3627 , b/178751994 )

AccessibilityScrollState was renamed to ScrollAxisRange. horizontalAccessibilityScrollState was renamed to horizontalScrollAxisRange. verticalAccessibilityScrollState was renamed to verticalScrollAxisRange. ( Id3148 )
• Removed PointerInputData and modified PointerInputChange to give it all of PointerInputData's fields. Made PointerInputEvent and PointerInputEventData internal because they aren't used in any public API. ( Ifff97 , b/175142755 )
• 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 )
• Removed experimental monotonicFrameAnimationClockOf methods ( Ib753f , b/170708374 )
• Move String.fintPrecedingBreak and String.fingFollowingBreak to InternalTextApi. ( I657c4 )

رفع اشکال

• 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 )

Breaking Change

• 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

• VisualTransformation API Changes

  • Renamed OffsetMap to OffsetMapping
  • Renamed OffsetMapping.identityOffsetMap to OffsetMapping.Identity
  • PasswordTransformation is no longer data-class

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 )

• subcomposeInto(LayoutNode) was made internal ( Id724a )

• 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 اشکال

• 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 )

• Removed extension methods on Float and Double to convert values to radians. Moved to be a private function within the implementation PathParser which was the only place where it was used ( I25f52 )

• New methods placeable.placeWithLayer() and placeable.placeRelativeWithLayer() were added which allows custom layouts and layout modifiers to place a child with introducing a graphics layer for their drawing. Having that we can first optimize redrawings, so when we need to move a child we don't have to redraw its content, second we can apply draw transformations for a child ( Ibd8f6 , b/170296989 , b/171493718 , b/173030831 )

• Added lint check for composable lambda parameter naming and position, to check for consistency with Compose guidelines. Also migrated some APIs using children as the name for their trailing lambda to content , according to the lint check and guidance. ( Iec48e )
• Added API to check if Alt, Ctrl, Meta or Shift modifier keys were pressed when a keyevent was dispatched. ( I50ed9 )
• Added a new Modifier.drawLayer() overload. It takes a lambda block on a new GraphicsLayerScope where you define the layer parameters in a way which allows to skip recomposition and relayout when the state change happens. DrawLayerModifier is now internal in preparation to migrating its logic into placeable.placeWithLayer() method of LayoutModifier ( I15e9f , b/173030831 )
• Deprecated Ambients named with Ambient as their suffix, and replaced them with new properties prefixed with Ambient, following other Ambients and Compose API guidelines. ( I33440 )
• Moved androidx.compose.ui.text.Typeface to androidx.compose.ui.text.font.Typeface ( Ic2b81 )

• Renamed ImageAsset and related methods to ImageBitmap. ( Ia2d99 )
• Add zIndex param for the PlacementScope's place() so Modifier.zIndex() now works as a LayoutModifier and any custom layout can set zIndexes for their children right in the placement block ( I711f7 , b/171493718 )
• Moved foundation semantics properties to ui ( I6f05c )
• Deprecate place(Offset) and placeRelative(Offset). Use overloads with int offsets instead ( I4c5e7 )
• Previously Deprecated APIs were removed: Modifier.onPositioned was removed, use Modifier.onGloballyPositioned. Modifier.onDraw was removed, use Modifier.onDrawBehind. Modifier.plus was removed, use Modifier.then. Color.Unset was removed, use Color.Unspecified. PxBounds class was removed, use Rect instead. ( Ie9d02 , b/172562222 )
• The Alignment interface was updated and made functional. ( I46a07 , b/172311734 )
• Gesture detector for tap, double-tap, long press, and press indication were added using the new suspending pointer input. A few utilities were added as well, making it easier for developers to write their own gesture detectors. ( I00807 )
• id was renamed to layoutId for LayoutIdParentData . Measurable.id was renamed to Measurable.layoutId . ( Iadbcb , b/172449643 )
• New multitouch gesture detector, including helpers for detecting rotation, zoom, and panning. ( Ic459d )
• Introduced SweepGradientShader and SweepGradientBrush APIs. ( Ia22c1 )
• Time control in tests (TestAnimationClock and its usages) is now experimental ( I6ef86 , b/171378521 )

• Add coroutine-based scrolling APIs:

  Adds LazyListState.snapToItem and LazyListState.smoothScrollBy, as well as lower-level APIs for scroll control. These APIs provide a suspend interface to control scrolling that waits until the scroll is finished before returning. ( Ie5642 )

• Modifier.focusable has need added in foundation. Use this to add focusable behavior to a component, with correct semantics and accessibility. ( I41eb9 , b/152525426 , b/162865824 )

• Provide default implementations of methods and properties in AnimationClockTestRule that can be delegated to its clock ( I7ea3d , b/173399709 )

• AndroidComposeTestRule can now accept custom activity launchers ( Ib8288 , b/153623653 , b/154135019 )

• TextLayoutResult.getLineVisibleEnd is deprecated. As a replacement TextLayoutResult.getLineEnd now has a new parameter visibleEnd. ( I73282 )

• Updated TextFieldValue API

  • made TextFieldValue.composition readonly
  • removed exception thrown for invalid selection range ( I4a675 , b/172239032 )

• New APIs for running animations in coroutines ( Ied662 )

رفع اشکال

• The alignment parameter of Box was renamed to contentAlignment. ( I2c957 )
• offsetPx modifiers were renamed to offset. They are now taking lambda parameters instead of State. ( Ic3021 , b/173594846 )
• Added resetInput parameter to TextInputService#onStateUpdated ( I3e8f5 , b/172239032 , b/171860947 )

• Temporarily added option to let the TestAnimationClock be driven by the MonotonicFrameClock ( I1403b , b/173402197 )
• Added Android Typeface wrapper. You can load an Android Typeface via typeface function ie typeface(Typeface.DEFAULT) . Also renamed typefaceFromFontFamily() to typeface() ( I52ab7 )
• Added lint check to check that Modifier factory functions are defined as extensions on Modifier, so they can be fluently chained together. ( I07981 )
• Remove old ui-test module and its stubs ( I3a7cb )
• Recomposer no longer accepts an EmbeddingContext; required scheduling dependencies are obtained from the effectCoroutineContext. FrameManager is deprecated; platform integrations should initialize their own global snapshot handling. ( I02369 )
• Pass style information to accessibility node. ( If5e8d )

نسخه 1.0.0-alpha06

28 اکتبر 2020

androidx.compose.ui:ui-*:1.0.0-alpha06 is released. نسخه 1.0.0-alpha06 حاوی این commit ها است.

تغییرات API

• Recomposer is now a CompositionReference and a valid composition parent. Explicit Recomposer is now required in fewer places. ( I4036f )
• Deprecate VectorPainter in favor of rememberVectorPainter to better indicate that the composable API internally leverages 'remember' to persist data across compositions. ( Ifda43 )
• 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 )

• Updated Size.Unspecified parameters to be Float.NaN instead of Float.POSITIVE_INFINITY. Updated Painter implementations to check against Size.Unspecified as well as non-finite Sizes. ( I95a7e )
• The order of place() calls in custom Layouts now defines the drawing order for the children ( Ibc9f6 )
• Support AnnotatedString to SpannableString conversion for accessibility. ( Ief907 )
• Added stubs for android classes that are on older platforms to avoid use of reflection when possible. ( Ia1790 )

• foundation.Box was deprecated. Please use foundation.layout.Box instead. ( Ie5950 , b/167680279 )
• Stack was renamed to Box. The previously existing Box will be deprecated in favor of the new Box in compose.foundation.layout. The behavior of the new Box is to stack children one on top of another when it has multiple children - this is different from the previous Box, which was behaving similar to a Column. ( I94893 , b/167680279 )
• Box decoration parameters have been deprecated. If you want to have decorations/padding on your box, use Modifiers instead (Modifier.background, Modifier.border, Modifier.padding) ( Ibae92 , b/167680279 )

• Modifier.plus has been deprecated, use Modifier.then instead. 'Then' has a stronger signal of ordering, while also prohibits to type Modifier.padding().background() + anotherModifier , which breaks the chain and harder to read ( Iedd58 , b/161529964 )
• Add [Abstract]ComposeView View subclasses for hosting Compose content in a View hierarchy. ( I46357 )
• Row and Column are now inline function significantly reducing the overhead of using them. ( I75c10 )

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

  15. Updated Image composable to avoid Box usage for less overhead
  16. Updated Outline class to have @Immutable annotations
  17. Updated PathNode to have @Immutable annotations for each path instruction

  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 )

  • 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 )

• 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 )

• 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 اشکال

• 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 زمان اجرا 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 )
