Интерфейс создания

Структура

Compose — это комбинация из 7 идентификаторов групп Maven в androidx . Каждая группа содержит определённый набор функций, каждый из которых сопровождается собственным набором заметок о выпуске.

В этой таблице объясняются группы и ссылки на каждый набор заметок о выпуске.

Объявление зависимостей

Чтобы добавить зависимость от Compose, необходимо добавить репозиторий Google Maven в свой проект. Подробнее см. в репозитории Google Maven .

Добавьте зависимости для необходимых артефактов в файл build.gradle вашего приложения или модуля:

dependencies {
    implementation "androidx.compose.ui:ui:1.9.4"
}

android {
    buildFeatures {
        compose true
    }

    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.15"
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

dependencies {
    implementation("androidx.compose.ui:ui:1.9.4")
}

android {
    buildFeatures {
        compose = true
    }

    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.15"
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

Версия 1.10

Версия 1.10.0-beta01

22 октября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.10.0-beta01 . Версия 1.10.0-beta01 содержит следующие коммиты .

Изменения API

• Добавляет оптимизацию для диспетчеризации смены фокуса. Эту оптимизацию можно отключить с помощью isOptimizedFocusEventDispatchEnabled = false ( I919fb , b/449228515 ).
• Обновляет все API косвенного касания, чтобы использовать имя API косвенного указателя для соответствия API ввода указателя. ( I238ce , b/451607214 )
• Функции TextDirection , TextAlign , Hyphens , FontSynthesis valueOf теперь выдают исключение IllegalArgumentException при получении неизвестного значения. ( I07c67 )
• Обновите CompositionDataTree.makeTree для передачи значений по умолчанию вместо функции-оболочки. ( Id64a6 , b/445229688 )
• API тестовых правил createComposeRule , createAndroidComposeRule и createEmptyComposeRule , которые принимают параметр effectContext , стабильны, а параметр по умолчанию равен EmptyCoroutineContext . ( If400c , b/450540702 )
• UnplacedStateAwareModifierNode был переименован в UnplacedAwareModifierNode ( I6a551 , b/449719932 )
• Отменить оптимизацию захвата контента ( Ic000b , b/442364065 )
• Добавлен флаг функции ComposeUiFlags.isRectManagerOffsetUsageFromLayoutCoordinatesEnabled . Он обеспечивает оптимизацию производительности, когда запросы координат, такие как LayoutCoordinates.positionInRoot() используют кэшированные смещения, которые уже есть в RectManager , вместо того, чтобы проходить по всему дереву при каждом вызове. ( Ieaadc )

Исправления ошибок

• PlaceholderSpan теперь корректно использует нелинейное масштабирование шрифта для изменения размера ( Id2ead , b/324462728 ).
• Используйте ViewCompat для реализации констант тактильной обратной связи, поддерживаемых на уровне платформы, полагаясь на его резервную поддержку для новых констант. ( Ib5a00 )

Версия 1.10.0-альфа05

8 октября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.10.0-alpha05 . Версия 1.10.0-alpha05 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка, из-за которой вложенные всплывающие окна неправильно располагались в верхней части экрана; теперь они правильно привязываются к родительскому всплывающему окну. ( Id4603 , b/191279752 )
• Исправлена ​​проблема с переносом фокуса на другие представления в иерархии. ( I95223 , b/446028624 )
• Исправлены поля со встроенными параметрами, отсутствующими в инспекторе в лямбда-выражениях, созданных Kotlin 2.2.20 ( I9855d , b/447110005 ).
• Исправлено затенение имен ресурсов автозаполнения между пользовательским интерфейсом и базовыми модулями ( I5da5a ).

Внешний вклад

• Объект UiModes переименован в AndroidUiModes, чтобы отразить, что его константы взяты из Android API. ( Ia0a77 )

Версия 1.10.0-альфа04

24 сентября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.10.0-alpha04 . Версия 1.10.0-alpha04 содержит следующие коммиты .

Изменения API

• Вариант тестового правила Compose, принимающий параметр CoroutineContext , переведен в стабильную версию. Экспериментальная аннотация удалена, и разработчикам больше не требуется согласие на использование этого API. ( I74e6e )
• ComposeUiFlags.isRectTrackingEnabled был удалён. Эта логика не всегда включена. ( Id78df )
• Устаревшая встроенная перегрузка Updater#set поскольку она слишком много раз упаковывала предоставленное значение ( Id679e ).
• Отметить семантическое свойство onAutofillText как устаревшее. ( I6f81c )
• Введен класс UnplacedStateAwareModifierNode . Он предоставляет функцию обратного вызова, которая вызывается, когда ранее размещённый макет больше не размещается. ( I8fdd8 , b/309776096 )
• Исправлена ​​документация RetainObserver.onRetained и добавлен RetainObserver.onUnused , который является зеркалом RememberObserver.onAbandoned . ( Ia6fc5 )
• Добавлен onVisibilityChangedNode() , который создает Modifier.Node , используемый Modifier.onVisibilityChanged() через делегирование, что позволяет расширить эту функциональность в вашем пользовательском Modifier.Node . ( I70d84 , b/443001320 )

Исправления ошибок

• Исправлена ​​ошибка, из-за которой встроенное содержимое не отображалось при размещении на последней строке многострочного текста с многоточием, несмотря на наличие заполнителя перед областью с многоточием. ( I76aaf , b/441829208 )

Версия 1.10.0-альфа03

10 сентября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.10.0-alpha03 . Версия 1.10.0-alpha03 содержит следующие коммиты .

Изменения API

• Переименовывает DelegatableNode.invalidateLayoutForSubtree в DelegatableNode.invalidateMeasurementForSubtree . ( I94257 , b/430106107 )
• Удаляет избыточный сопоставитель isInHiddenAccessibilitySubtree . ( I4476c , b/443792965 )
• Вводит трассировки стека Compose на основе групповых ключей, которые включены по умолчанию для всех минимизированных приложений. Сопоставление Proguard для этих трассировок будет генерироваться плагином Gradle для компилятора Compose, начиная с версии Kotlin 2.3.0. ( Ifbcb5 )
• Modifier.skipToLookaheadSize теперь использует включенную по умолчанию лямбду, которая включает пропуск размера только при активном общем переходе, так же, как Modifier.skipToLookaheadPosition . ( Ibe0f5 , b/432485585 )
• ComposeUiFlags.isOutOfFrameDeactivationEnabled удален, и эта функциональность теперь всегда включена. ( I421ed )
• Перенесите фабричные функции для создания экземпляров FillableData в сопутствующий объект. Вместо вызова FillableData(value) используйте новые фабричные методы: FillableData.createFrom(value) . ( I2e200 , b/441719650 )
• Введен BeyondBoundsLayoutModifierNode — новый узел-модификатор для выполнения макета за пределами границ для поиска фокуса. ( I39be1 , b/416133658 )
• FocusTargetModifierNode.requestFocus() передаёт фокус одному из своих дочерних элементов, когда сам этот элемент не может быть сфокусирован. Теперь это согласуется с FocusRequester.requestFocus() и FocusRequesterModifierNode.requestFocus() . Если вам не нужно такое поведение, установите флаг ComposeUiFlags.isRequestFocusOnNonFocusableFocusTargetEnabled в вашем приложении в значение false. ( Icca5c , b/436863604 )
• Укажите размер окна на основе DP в WindowInfo ( I9322b , b/424442112 )
• Удален флаг isNestedScrollDispatcherNodeFixEnabled . ( If451a )
• Добавить поддержку значений даты при автозаполнении в API FillableData . Добавлено val dateMillisValue: Long для извлечения информации о дате и соответствующий конструктор FillableData(dateMillisValue: Long) для создания экземпляров FillableData на основе даты. ( Id072a )

Внешний вклад

• Объект UiModes введен для объявления констант, используемых для аннотации UiMode ( I03cb8 ).

Версия 1.10.0-альфа02

27 августа 2025 г.

Выпущен androidx.compose.ui:ui-*:1.10.0-alpha02 . Версия 1.10.0-alpha02 содержит следующие коммиты .

Изменения API

• Обновление FillableData для поддержки нетекстовых компонентов, таких как переключатели и списки, включая логические и целочисленные значения внутри FillableData , а также фабричные конструкторы для создания экземпляров FillableData с логическими значениями и списками, которые преобразуются в AutofillValue платформы. Также добавлены соответствующие семантические свойства и действия. ( Ia8105 , Icc5cf )
• В несенсорном режиме система просмотра назначает начальный/по умолчанию фокус одному из доступных для фокусировки элементов на экране. Эта функция добавлена ​​в Compose и может быть включена с помощью ComposeUiFlags.isInitialFocusOnFocusableAvailable . ( Ib9178 )
• Удален флаг isPointerInteropFilterDispatchingFixEnabled . ( Iaa589 )
• Удален флаг isNestedScrollInteropPostFlingFixEnabled . ( I2a756 )
• Добавьте семантические сопоставления isHiddenFromAccessibility() и isInHiddenAccessibilitySubtree() . ( I9f5a1 )
• Добавлен runCurrent() в MainTestClock для запуска всех запланированных задач на базовом планировщике. Это необходимо для поддержки запуска тестов на StandardTestDispatcher , где задачи добавляются в планировщик, а не выполняются немедленно, если у них есть задержка 0 мс. Тест можно настроить на использование StandardTestDispatcher , создав правило ComposeTestRule и передав ему StandardTestDispatcher . По умолчанию тесты запускаются на UnconfinedTestDispatcher , и в этом случае runCurrent() не требуется вызывать.
• Добавлена ​​поддержка запуска тестов в StandardTestDispatcher . Исторически тестовый фреймворк был (и до сих пор существует) настроен с использованием UnconfinedTestDispatcher , что несколько отличается от производственной среды. Теперь вы можете изменить эту настройку, создав собственный StandardTestDispatcher и добавив его в effectContext при создании ComposeTestRule (или при вызове runComposeUiTest ). ( I334d0 , b/254115946 )
• Обновление кода для создания дерева узлов из SlotTree . ( I997d3 )

Исправления ошибок

• Интерфейс Compose UI теперь устанавливает RetainScopes с учётом жизненного цикла на Android. По умолчанию значения с атрибутом retain теперь сохраняются при изменении конфигурации. ( Id4a09 , b/177562901 )

Внешний вклад

• Добавляет возможность VelocityTracker рассчитывать скорость указателя на основе отслеживаемых событий указателя, используя специфичное для платформы поведение. ( I621e8 )

Версия 1.10.0-альфа01

13 августа 2025 г.

Выпущен androidx.compose.ui:ui-*:1.10.0-alpha01 . Версия 1.10.0-alpha01 содержит следующие коммиты .

Изменения API

• Наведение указателя мыши или сенсорной панели в ComposeView теперь автоматически снимает фокус, если наведение указателя не происходит в пределах сфокусированного узла. Это приводит к пользовательскому опыту, характеризующемуся «нажатием для снятия фокуса», что более ожидаемо, чем текущее поведение при использовании устройств ввода с указателем. От этого поведения можно отказаться с помощью нового API AbstractComposeView.isClearFocusOnPointerDownEnabled . ( I6322b , b/282963174 )
• Представлен интерфейс FillableData для поддержки различных типов компонентов автозаполнения, помимо текста. ( If9bd2 )
• Новый API для динамического включения и отключения общих элементов, который также позволяет учитывать, происходит ли уже переход общего элемента. Новый API для установки альтернативных целевых границ при удалении целевого общего элемента во время перехода. Новый API для получения LayoutCoordinates объекта LookaheadScope . ( I18dd4 , b/409819304 , b/395670637 )
• Введен флаг isNestedScrollInteropIntegerPropagationEnabled для управления экспериментом по отправке корректных целых чисел во вложенное взаимодействие прокрутки. ( If8316 )
• Добавлен requestFocusForChildInRootBounds() в DelegatableNode для перемещения фокуса на дочерний элемент, который перекрывает заданный прямоугольник. ( I001ef )
• Удалены флаги isOnScrollChangedCallbackEnabled , isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled , isFlingContinuationAtBoundsEnabled , isAutomaticNestedPrefetchEnabled , DragGesturePickUpEnabled , isPointerInteropFilterDispatchingFixEnabled , isNestedScrollInteropPostFlingFixEnabled , isNestedScrollDispatcherNodeFixEnabled ( I36c18 ).
• Добавлена ​​аннотация @CheckResult для функций поиска и селектора SemanticsNode , чтобы обеспечить использование возвращаемых значений. ( I6f86e , b/201652748 )
• Улучшить производительность процесса захвата контента ( I3c7c0 )
• Введен CompositionLocal , который можно использовать для изменения кисти подсветки успешного заполнения Autofill. ( I52329 )
• Представлен новый интерфейс Interpolatable, который позволяет автоматически интерполировать различные типы, предполагая, что один тип умеет преобразовывать другой. Этот интерфейс используется в нескольких типах компоновки, таких как Brush и Shape, но может использоваться и извне. ( I58eab )
• Теперь Scrollable лучше поддерживает двумерные события прокрутки колесика мыши. Добавлен новый тестовый API для тестирования вариантов использования в MouseInjectionScope . Мы также добавили новую перегрузку для методов прокрутки в MouseInjectionScope и флаг для управления новым поведением — isMouseWheel1DAxisLockingEnabled ( I136df ).
• Добавьте DeviceConfigurationOverrides для типа и состояния клавиатуры, типа и состояния навигации, состояния сенсорного экрана и типа режима пользовательского интерфейса ( I282f0 ).
• Добавлен новый режим LineHeightStyle.Mode под названием Tight . Этот режим помогает добиться меньшей высоты строк, даже если это может привести к обрезанию более высоких глифов. ( Id3849 )
• BaselineShift теперь имеет значение Unspecified, что позволяет избежать упаковки. BaselineShift , Hyphens , LineBreak , TextAlign и TextDirection теперь имеют вспомогательные функции isSpecified Hyphens , TextAlign , TextDecoration и TextDirection теперь имеют методы valueOf() и value, что позволяет эффективно сериализовать/десериализовать. ( I8d44c )
• Добавлен новый интерфейс метода getDisplayName , позволяющий настраивать отображаемые имена для экземпляров параметров предварительного просмотра. ( I19bdf , b/241699422 )
• При сравнении значений Dp с Unspecified с использованием операторов «меньше» или «больше» теперь всегда возвращается значение «false». Использование Dp.compareTo(Unspecified) всегда возвращает 0. Установка флага ComposeUiUnitFlags.isDpCompareToChanged в значение «false» вернёт Dp.compareTo() к прежнему поведению, при котором сравнение Unspecified с операторами «меньше» и «больше» не всегда возвращало значение «false», а compareTo() с Unspecified соответствует поведению Float.compareTo() . ( Ifa88b , b/429221319 )

Исправления ошибок

• Перемещение minSdk по умолчанию из API 21 в API 23 ( Ibdfca , b/380448311 , b/435705964 , b/435705223 )
• Исправлена ​​ошибка, из-за которой не создавалось новых AndroidComposeViews во время перехода. ( I2e23e , b/340894487 , b/287484338 )
• Исправлена ​​ошибка цвета при использовании векторного рисунка, использующего один цвет, а fillColor не является ни полностью непрозрачным, ни полностью прозрачным. ( I3b041 , b/328677973 )
• Исправлена ​​ошибка, из-за которой значки, загруженные через painterResource с цветами, специфичными для темы, не обновлялись при изменении темы. ( I85ea0 , b/424416571 )
• Введение в семантику onFillData и fillableData ( I45d9e )
• Платформо-специфичное кодирование состояния теперь всегда включено в StateRestorationTester . Это согласует поведение теста с реальным восстановлением состояния приложения, например, с Parcelization на Android. ( I38211 , b/408154192 , b/382294247 )
• Исправлены случайные сбои при запросе фокуса. ( 57b31a11 , b/431111149 )

Версия 1.9

Версия 1.9.4

22 октября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.4 . Версия 1.9.4 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка, из-за которой встроенный текст исчезал, если он находился на последней строке многострочного текста с многоточием, даже если встроенный текст не находился в области с многоточием. ( I76aaf , b/441829208 )
• Исправлена ​​ошибка, из-за которой обратные вызовы модификатора onLayoutRectChanged не всегда вызывались, если debounceMillis не равен нулю. ( 72aba47 , b/445324854 )

Версия 1.9.3

8 октября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.3 . Версия 1.9.3 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка, из-за которой модификаторы onVisibilityChanged/onFirstVisible/onLayoutRectChanged не получали обратные вызовы, если перемещаемый макет имел более 170 потомков. ( 4f2fdd , b/445356774 )

Версия 1.9.2

24 сентября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.2 . Версия 1.9.2 содержит следующие коммиты .

Исправления ошибок

• Modifier.onVisibilityChanged() теперь корректно срабатывает при отсоединении или повторном использовании узла. ( Ic5ce20 )
• Modifier.onVisibilityChanged() и onLayoutRectChanged() теперь правильно обрабатывают родительские макеты, используя placeWithLayer() для размещения дочерних элементов. ( Ia05ac9 )
• Для Modifier.onVisibilityChanged() и onLayoutRectChanged() правильно уведомляйте в особых случаях, таких как удаление слоя/модификатора слоя или обновление свойств слоя. ( Ia05ac )

Версия 1.9.1

10 сентября 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.1 . Версия 1.9.1 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка цвета при использовании векторного рисунка, использующего один цвет, а fillColor не является ни полностью непрозрачным, ни полностью прозрачным. ( I3b041 , b/328677973 )

Версия 1.9.0

13 августа 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0 . Версия 1.9.0 содержит следующие коммиты .

Важные изменения с версии 1.8.0

• Важные изменения в версии 1.9.0 описаны в этой записи блога.
• Для проверок lint, поставляемых вместе с Compose, теперь требуется версия AGP не ниже 8.8.2. Если вы не можете обновить AGP, вы можете обновить Lint самостоятельно, указав android.experimental.lint.version=8.8.2 (или более новую версию) в файле gradle.properties . Для запуска проверок lint Compose в среде IDE требуется Android Studio Ladybug или более новая версия.
• Критическое изменение: модификатор graphicsLayer теперь реализует SemanticsModifierNode . Это может привести к добавлению новых SemanticsNodes в дерево семантики и, следовательно, к сбоям в тестах, делающих предположения о его структуре. Например, тесты, использующие onChild , onParent , onSibling и другие подобные методы для проверки утверждений, могут завершиться сбоем, если между текущим и целевым узлами добавляется новый узел. Предпочтительный способ исправления этих сбоев — непосредственное добавление testTag к целевому узлу. Другой подход — использование более свободного сопоставления, например onNode(hasAnyAncestor(hasText("ancestor")) and hasText("target")) . ( I638b5 )

Версия 1.9.0-rc01

30 июля 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-rc01 . Версия 1.9.0-rc01 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка, из-за которой значки, загруженные через painterResource с цветами, специфичными для темы, не обновлялись при изменении темы системы. ( I85ea0 , b/424416571 )
• Исправлены ошибки в API 21 (Lollipop) и 28 (Pie), из-за которых важные графические методы были переименованы в процессе оптимизации. ( Iebf99 , b/425120571 , b/420462749 )
• Убедитесь, что вновь вставленные модификаторы onLayoutRectChanged вызываются изначально. ( l9aa91 ), ( lb348a )
• Исправлена ​​ошибка, из-за которой кэш смещения некорректно становился недействительным, что приводило к вызову модификаторов onLayoutRectChanged с неправильными координатами ( ibd4cd ), ( lddc57 )
• Исправлена ​​ошибка, из-за которой повернутые/перекошенные макеты получали неверные координаты с помощью модификаторов onLayoutRectChanged ( lddc57 , b/426750475 )

Внешний вклад

• Исправлена ​​ошибка, из-за которой элементы dragAndDropSource в LazyList исчезали при прокрутке. Спасибо, Виктор Рендина! ( dc3bcd3 , b/425894792 )

Версия 1.9.0-beta03

16 июля 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-beta03 . Версия 1.9.0-beta03 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка, из-за которой равномерно размытые внутренние тени не перемещались правильно при смещении.

Версия 1.9.0-beta02

2 июля 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-beta02 . Версия 1.9.0-beta02 содержит следующие коммиты .

Изменения API

• Изменяет сопутствующий объект на экспериментальный для соответствия классу. ( I8452a )
• Удален экспериментальный флаг isTrackFocusEnabled ( I003fd ).

Исправления ошибок

• Если ни один WindowInsets не проникает в содержимое ComposeView , значения WindowInsetsRulers не предоставляются. ( I71221 )

Версия 1.9.0-beta01

18 июня 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-beta01 . Версия 1.9.0-beta01 содержит следующие коммиты .

Критические изменения

• Узлы модификатора graphicsLayer теперь реализуют SemanticsModifierNode . Это может привести к добавлению новых SemanticsNodes в дерево семантики и, следовательно, к сбоям в тестах, делающих предположения о его структуре. Например, тесты, использующие onChild , onParent , onSibling и другие подобные методы для проверки утверждений, могут завершиться сбоем, если между текущим и целевым узлами добавляется новый узел. Предпочтительный способ устранения этих сбоев — непосредственное добавление testTag к целевому узлу. Другой подход — использование более свободного сопоставления, например onNode(hasAnyAncestor(hasText("ancestor")) and hasText("target")) . ( I638b5 )

Изменения API

• Изменен ShadowContext на герметичный интерфейс ( I3ce40 ).
• Добавляет межмодульный способ создания события косвенного касания (для тестирования) ( I22e4c )
• Делает IndirectTouchEvent.nativeEvent экспериментальным. ( I6fda5 )
• Пересматривает API-интерфейс на основе отзывов совета API. ( Ibf378 )
• Удалить константу FrameRateCategory.NoPreference . Переименовать Modifier.requestedFrameRate в Modifier.preferredFrameRate . ( I2f976 )
• WindowInsetsRulers : значение rulersIgnoringVisibility изменено на максимальное. Функция getDisplayCutoutBounds() теперь является функцией расширения PlacementScope . WindowInsetsAnimationProperties изменена на WindowInsetsAnimation , а getAnimationProperties() — на getAnimation() . ( I3816f )
• Изменен класс ShadowParams на Shadow ( I11cca )
• Измените пакет для API частоты кадров с androidx.compose.ui.ui на androidx.compose.ui ( I8994e )
• Изменён InsetsRulers , чтобы он находился в общем коде с именем WindowInsetsRulers . API упрощён, теперь все вставки являются WindowInsetsRulers . Свойства анимации, не относящиеся к линейкам, извлечены в класс AnimationProperties . Для объединения нескольких классов WindowInsetsRulers можно использовать WindowInsetsRulers.innermostOf() . ( I2f0c6 , b/415012444 )
• Добавлен инструментальный API для анализа исходной информации, добавленной компилятором Compose. ( Iceaf9 , b/408492167 )

Исправления ошибок

• Флаг isGetFocusedRectReturnEmptyEnabled был удален, поскольку эта функция полностью проверена. ( Ife722 )
• Исправлена ​​ошибка в performScrollToNode , из-за которой в некоторых случаях не достигался целевой узел. Благодаря этому исправлению в таких случаях целевой узел должен достигаться всегда. Побочным эффектом этого изменения является то, что точное положение прокрутки в конце действия теперь может отличаться, что влияет на тесты скриншотов и тесты, предполагающие точное положение прокрутки. ( I2c8a1 )

Версия 1.9.0-альфа04

4 июня 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-alpha04 . Версия 1.9.0-alpha04 содержит следующие коммиты .

Изменения API

• Добавлены API-интерфейсы модификаторов для настраиваемых теней. ( I2058d , b/160665122 )
• Добавьте свойство SemanticsModifierNode.isImportantForBounds , которое определяет, следует ли учитывать узел при вычислении границ. Свойство имеет значение true по умолчанию и может быть установлено в false, чтобы указать, что узел не следует учитывать при вычислении границ. ( I7ebec )
• Добавьте фабричную функцию SemanticsPropertyKey для объявления свойств семантики, специфичных для Android, которые становятся доступными как дополнительные возможности доступа через AccessibilityNodeInfo.getExtras . ( I2ed51 )
• Удалены все использования ComposeUiFlags.isRemoveFocusedViewFixEnabled и этот флаг объявлен устаревшим. ( I50328 )
• Представлен новый настраиваемый фреймворк для построения теней. Он включает DropShadowPainter и InnerShadowPainter , а также зависимости DropShadow/InnerShadow . Инфраструктура построения теней является общей, что позволяет использовать одни и те же сгенерированные тени в нескольких точках вызова без необходимости их повторной генерации n раз. ( I24f7a , b/160665122 )
• Представлены CompositeShader и CompositeShaderBrush , создающие комбинированный результат двух шейдеров. Также добавлен ShaderBrush#transform для задания матрицы преобразования для шейдера. ( I2621a , b/160665122 )

Исправления ошибок

• Исправлена ​​ошибка в NestedScrollInteropConnection , из-за которой методы fling располагались в неправильном порядке относительно представлений. ( I56ad4 )
• Ранее диалоговые окна, отображавшиеся на весь экран, не отображались в области выреза экрана. Эта ошибка исправлена, и теперь диалоговые окна с параметрами decorFitsSystemWindows = false и usePlatformDefaultWidth = false могут отображать область выреза экрана. ( I9e975 )
• Исправлена ​​ошибка, из-за которой зеленый индикатор фокуса TalkBack не отображался после включения, когда приложение Compose работало в фоновом режиме. ( Ifd12a )

Версия 1.9.0-альфа03

20 мая 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-alpha03 . Версия 1.9.0-alpha03 содержит следующие коммиты .

Изменения API

• Флаг ComposeUiFlags.isGetFocusedRectReturnEmptyEnabled позволяет при отсутствии фокусируемого элемента ComposeView устанавливать прямоугольник в значение Empty. Это предотвращает выбор объекта View при поиске фокуса. Это особенно важно, когда редактор метода ввода (IME) имеет параметр NEXT, при котором он может попытаться сфокусироваться на ComposeView , а requestFocus() завершится неудачей. ( Ibd0e2 , b/369256395 )
• Ввести флаг isNestedScrollDispatcherNodeFixEnabled . ( I0d24a )
• Переименуйте dialogContentTitle в DialogProperties в windowTitle ( Ibd27b )
• Были введены модификаторы Modifier.onFirstVisible и Modifier.onVisibilityChanged — высокоуровневые модификаторы, построенные на основе Modifier.onLayoutRectChanged . Эти модификаторы специально разработаны для решения множества распространённых задач приложений, таких как регистрация показов, автоматическое воспроизведение видео и т. д. Они разработаны с учётом производительности, чтобы их можно было использовать в критически важных сценариях со списками без риска снижения производительности прокрутки. Помимо этих API модификаторов, были добавлены дополнительные API для RelativeLayoutBounds для поддержки этих вариантов использования, а также для упрощения разработчиками создания аналогичных пользовательских модификаторов, точно соответствующих их задачам. ( I759b8 )
• Измените setDiagnosticStackTraceEnabled на экспериментальный, чтобы учесть будущую разработку этой функции. ( I11db3 )
• Представлены Modifier.scrollable2D , Scrollable2DState и сопутствующие API для создания состояний. Также представлены общие функции расширения прокрутки. ( Ic61c8 , b/214410040 )
• 64-битные цветовые значения Compose нельзя напрямую сравнивать с цветовыми пространствами Android ColorLongs , поскольку для некоторых цветовых пространств идентификаторы цветовых пространств не упорядочены. Для преобразования в цветовые пространства Android и обратно добавлены два новых API: toColorLong() и fromColorLong() . ( I36899 )
• Введен ViewConfiguration.minimumFlingVelocity для управления нижней границей скорости подбрасывания. ( I11aab )

Версия 1.9.0-альфа02

Выпущен androidx.compose.ui:ui-*:1.9.0-alpha02 . Версия 1.9.0-alpha02 содержит следующие коммиты .

Изменения API

• Добавьте dialogContentTitle в DialogProperties , который задает заголовок окна содержимого. bf9d670

Исправления ошибок

• Линейки вставок окон временно отключены, пока внутренние тесты исправляются. 8d1402
• Исправлено, как изменения ввода указателя добавляются в VelocityTracker в DragGestureNode . Это можно контролировать с помощью нового флага isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled . 254ddb

Версия 1.9.0-альфа01

23 апреля 2025 г.

Выпущен androidx.compose.ui:ui-*:1.9.0-alpha01 . Версия 1.9.0-alpha01 содержит следующие коммиты .

Изменения поведения

• Для проверок lint, поставляемых вместе с Compose, теперь требуется версия AGP не ниже 8.8.2. Если вы не можете обновить AGP, вы можете обновить Lint самостоятельно, указав android.experimental.lint.version=8.8.2 (или более новую версию) в файле gradle.properties . Для запуска проверок lint Compose в среде IDE требуется Android Studio Ladybug или более новая версия.

Изменения API

• Удаляет флаг, позволяющий выполнять трассировку операторов для отслеживания пути попадания (отладка). ( I1b2a1 )
• Изменены методы InnerRectRulers и OuterRectRules на методы. Удалён параметр name из публичного API RectRulers . DerivedRulers теперь является параметром конструктора для вертикальных и горизонтальных линеек. MergedHorizontalRulers и MergedVerticalRulers заменены методами minOf и maxOf для генерации экземпляров. ( Iee89f , b/408192133 )
• Отменить androidx.compose.ui.LocalSavedStateRegistryOwner в пользу androidx.savedstate.compose.LocalSavedStateRegistryOwner . ( I5439f , b/377946781 )
• Добавьте Modifier.keepScreenOn , чтобы дисплей не переходил в спящий режим во время присутствия ( Ib5af4 , b/408284174 )
• Добавить новое семантическое свойство Shape , которое может быть задано, когда форма элемента пользовательского интерфейса отличается от его ограничивающего прямоугольника, например, прямоугольник со скругленными углами. ( I1376f )
• Исправлена ​​проблема с диспетчеризацией событий указателя в AndroidViews и добавлен флаг isPointerInteropFilterDispatchingFixEnabled для защиты изменений. ( I0e272 , b/372055500 , b/408002332 )
• FocusRestorer больше не закрепляет ранее находившийся в фокусе элемент. Пользователям следует использовать ключ, чтобы убедиться, что ранее находившийся в фокусе элемент имеет тот же хэш состава, что и ранее находившийся в фокусе элемент, и чтобы фокус успешно восстанавливался. ( I4203b , b/330696779 )
• Разрешить Compose вызывать ViewTreeObserver.OnScrollChanged . Это поведение реализовано с помощью флага isOnScrollChangedCallbackEnabled . Мы также добавили функцию расширения DelegatableNode dispatchOnScrollChanged . ( I34b9d , b/238109286 )
• Метод currentCompositeKeyHash теперь устарел. Вместо него используйте currentCompositeKeyHashCode . Новый API кодирует тот же хеш с большим количеством бит, что экспоненциально снижает вероятность того, что две случайные несвязанные группы в иерархии композиции будут иметь одинаковый хеш-ключ. ( I4cb6a , b/177562901 )
• Для проектов, выпущенных с использованием Kotlin 2.0, требуется использование KGP 2.0.0 или более поздней версии ( Idb6b5 ).
• Добавлена ​​поддержка проверки линта для FocusRequester , чтобы убедиться, что он запомнен внутри композиции ( I6bf91 ).
• Добавлена ​​возможность устанавливать предпочтительную частоту кадров или категорию частоты кадров для Composable, которая должна отображаться на ( Ie5201 )
• Предоставьте нативный MotionEvent на Android. ( I17286 )
• Добавить getChecked() + setChecked(int) , отменить isChecked + setChecked(boolean) ( Iaac9d )
• Модификатор graphicsLayer теперь принимает blendMode и colorFilter ( Iab0e6 ).
• Добавлена ​​локальная композиция LocalResources для запроса ресурсов. Вызов LocalResources.current перекомпонует объект при изменении конфигурации, поэтому вызовы API, таких как stringResource() вернут обновлённые значения. ( I50c13 , b/274786917 )
• Предоставить экспериментальный API для Composables для обработки косвенных событий касания ( Icff57 )
• В этом выпуске улучшено оповещение о необработанных исключениях, возникающих на этапах макетирования и отрисовки компонуемого контента. Ранее необработанное исключение приводило к сбою программы выполнения тестов и преждевременному завершению набора тестов. Теперь эти исключения можно сообщать более корректно, не завершая набор тестов. ( I9928b , b/314128080 )
• Экспериментальный API GlobalAssertions объявлен устаревшим. Он предназначался для проверки доступности, для этого см. enableAccessibilityChecks() . ( I50aa5 )
• SemanticsNodeInteraction.performTextInputSelection больше не является экспериментальным и теперь поддерживает дополнительный параметр relativeToOriginal , который позволяет применять выделение либо к исходному непреобразованному тексту, либо к преобразованному тексту. ( I3a905 , b/261561038 , b/277018945 )
• Представить API для создания пользовательских маркированных списков через AnnotatedString ( I1d066 , b/383269496 , b/139326648 )
• Отменить использование runWithTimingDisabled в пользу runWithMeasurementDisabled , который более чётко описывает поведение — все метрики приостанавливаются. Кроме того, предоставить доступ к суперклассу MicrobenchmarkScope , поскольку повторное объявление функции runWithMeasurementDisabled для открытия доступа невозможно, так как она встроена. ( I9e23b , b/389149423 , b/149979716 )
• Обновлен API устройств ui-tooling для включения новых устройств. ( Ia2ac1 )
• Добавить планшетный портрет в коллекцию размеров экрана предварительного просмотра, чтобы помочь разработчику учитывать большие окна ( Ia1976 )
• Представляем API для отслеживания значений, позволяющее маркировать/регистрировать значения в заданный момент времени. Значения отображаются в Prefetto в виде новой полосы, которую можно просматривать на временной шкале отслеживания. На Android это реализовано с помощью Trace.setCounter . ( Idcf48 )

Исправления ошибок

• Исправлена ​​отправка наблюдателей запоминания в приостановленной композиции, чтобы избежать отправки запомненных/забытых в том же применении ( I570b2 , b/404645679 , b/407931790 ).
• android:dialogTheme теперь можно настроить для управления свойствами диалогового окна, когда decorFitsSystemWindows имеет значение false ( I7922f , b/246909281 )
• Исправлена ​​ошибка, из-за которой любое событие движения, обнаруженное за пределами диалогового окна, могло привести к закрытию диалогового окна. ( Ia78fd )
• Для проверки lint в Compose теперь требуется AGP версии не ниже 8.8.2 из командной строки и как минимум Android Studio Ladybug для поддержки IDE. Если вы используете более старую версию AGP, вы можете установить android.experimental.lint.version=8.8.2 в gradle.properties, чтобы обновить версию Lint, не затрагивая AGP. ( I6f2a8 )
• Добавлено новое семантическое свойство InputText , которое фиксирует значение textfield перед применением преобразования вывода. ( Iae46a , b/395911609 , b/176949051 )
• Перемещен API enableAccessibilityChecks() , который включает проверки доступности для Android, для разделения пакетов compose:ui:ui-test-accessibility если вы не используете TestRule , и compose:ui:ui-test-junit4-accessibility при вызове TestRule ( I3c318 , b/391560768 ).
• Добавлена ​​поддержка трассировок стека компоновки в LaunchedEffect и rememberCoroutineScope ( I705c0 , b/354163858 ).

Внешний вклад

• Изменена экспериментальная функция runComposeUiTest для принятия блока приостановки. Также добавлена ​​устаревшая функция runComposeUiTest для обеспечения двоичной совместимости ( I3b88c , b/361577328 ).

Исправления ошибок

• Флаг isGetFocusedRectReturnEmptyEnabled был удален, поскольку эта функция полностью проверена. ( Ife722 )
• Флаг ComposeUiFlags.isGetFocusedRectReturnEmptyEnabled позволяет при отсутствии фокусируемого элемента ComposeView устанавливать прямоугольник в значение Empty. Это предотвращает выбор объекта View при поиске фокуса. Это особенно важно, когда редактор метода ввода (IME) имеет параметр NEXT, при котором он может попытаться сфокусироваться на ComposeView , а requestFocus() завершится неудачей. ( Ibd0e2 , b/369256395 )

Версия 1.8.1

7 мая 2025 г.

Выпущен androidx.compose.ui:ui-*:1.8.1 . Версия 1.8.1 содержит следующие коммиты .

Исправления ошибок

• Исправлены некоторые проблемы с onLayoutRectChanged и LazyLayout d791b11
• Пропускать запросы на повторное измерение для предварительно составленных элементов. Эта ошибка влияла на производительность прокрутки ленивых макетов, поскольку в некоторых случаях предварительная выборка работала неэффективно, а измерение происходило внутри кадра. 742087a

Версия 1.8.0

23 апреля 2025 г.

Выпущен androidx.compose.ui:ui-*:1.8.0 . Версия 1.8.0 содержит следующие коммиты .

Важные изменения с версии 1.7.0

• В Compose 1.8 добавлена ​​поддержка семантического автозаполнения. Убедитесь, что используемые вами версии UI и Foundation — 1.8 или выше, так как для автозаполнения текстовых компонентов требуются последние версии обоих модулей. Подробнее об использовании API и примерах автозаполнения см. в документации по автозаполнению здесь .
• Compose 1.8 поддерживает дополнительные типы тактильной обратной связи: Confirm , ContextClick , GestureEnd , GestureThresholdActivate , Reject , SegmentFrequentTick , SegmentTick , ToggleOn , ToggleOff и VirtualKey . Доступ к ним осуществляется через LocalHapticFeedback , а на Android они доступны по умолчанию, если API Vibrator поддерживает тактильную обратную связь.
• Несколько API фокусировки теперь стабильны, включая Modifier.focusRestorer() , а также onEnter и onExit FocusProperties ( I6e667 ). Теперь вы можете указать FocusDirection при вызове requestFocus . Мы добавили API requestFocus(FocusDirection) в focusRequester и FocusTargetModifierNode , чтобы фокусировка в заданном направлении. (I5d9ec][https://android-review.googlesource.com/#/q/I5d9eca3a2cd283c1b84ad6b77d929ef9a49ce4cc], b/245755256 )

Версия 1.8.0-beta01

29 января 2025 г.

androidx.compose.ui:ui-*:1.8.0-beta01 is released. Version 1.8.0-beta01 contains these commits .

Изменения API

• ContextualFlowRow and ContextualFlowColumn have been marked as deprecated. This experimental component was introduced in 1.7 and had not yet been stabilized, and the implementation has been deemed undesirable. In the future, a component solving the use cases this component was meant to solve may be provided.
  • FlowRow and FlowColumn have experimental overloads that were introduced in 1.7 that include an overflow parameter. The use of this parameter has been deprecated, and the overloads without this parameter can be used instead. The default "overflow" behavior for these overloads will be "Clip", as it was since its introduction.
  • Many use cases for ContextualFlowRow can be accomplished using FlowRow, but we acknowledge that is not true in full generality. ContextualFlowRow is completely implementable in user-space, and one can attempt to copy its implementation and adapt if desired. In the future, we hope to solve these use cases in a different way. ( Ibafec )
• SemanticsNodeInteraction.semanticsId() has been removed. Use SemanticsNodeInteraction.fetchSemanticsNode().id instead. ( Ie397a )
• The old autofill APIs are deprecated. Use the new semantics based API instead. ( I943ff )
• Rewrite requestAutofill API to exist outside of autofill manager. ( Id1929 )

Исправления ошибок

• Fixed focus issue where requestFocus() with a nonsensical previouslyFocusedRect parameter (related to the focus direction) would skip past a ComposeView . ( Ifdc2f , b/388590015 )
• Fixed an occasional NPE when using GraphicsLayer.record { this@ContentDrawScope.drawContent() } . If you are recording drawContent() in this way, make sure to use the GraphicsLayer#record extension function inside DrawScope , and not the member function on GraphicsLayer . ( I75fc0 , b/389046242 )
• Fix text layout with ellipsis sometimes translating incorrectly during animations, see b/389707025 for more info ( Ie55b1 , b/389707025 )

Изменения API

• Making AutofillManager an abstract class. ( I0a3b0 )
• Fixed several focus-related issues, including crashes when IME tries to focus on ComposeView without focusable items, focus change within child AndroidViews , and focus request leaving an AndroidView . ( Ia03c3 , b/369256395 , b/378570682 , b/376142752 )
• Change FocusEnterExitScope.cancelFocus() to cancelFocusChange() ( I89959 )
• You may now calculate Composable occlusions with RectInfo.calculateOcclusions() .
• Added extension function on DelegatableNode to register a listener for global layout changes. ( I68b59 )

Исправления ошибок

• The activity that is used as the host for the composable under test when using ComposeContentTestRule.setContent now uses the theme Theme.Material.Light.NoActionBar , to avoid the ActionBar from overlapping with test content when targeting SDK 35. To opt out of this behavior, you can remove the dependency on ui-test-manifest and add an activity entry in your test app's AndroidManifest.xml for ComponentActivity with the theme of your choice. ( I7ae1b , b/383368165 )
• Resource fonts with the same variation settings will now avoid over-caching causing the incorrect variation settings to be applied. ( If3dff , b/372044241 )
• AnnotatedString.fromHtml now supports <ul>/<li> tags. ( I7c2fe , b/299662276 , b/139326648 )

Изменения API

• Exposed owner from LayoutNode for tools. ( I26f7f )
• Has LocalAutofillHighlightColor composition local use a Color type. ( I0e05b )
• Keep deprecated UrlAnnotation and its methods marked as experimental. ( Ic0021 )

Исправления ошибок

• Fixed IndexOutOfBoundsException crash when using LinkAnnotation inside the BasicText or Text composable ( be7605 , b/374115892 )
• Fixed issue where filled text fields with custom shape didn't clip the indicator line. ( I4f87f , b/380704151 )
• Fixed missing backgrounds with long screenshots. ( I4d57a )
• This library now uses JSpecify nullness annotations , which are type-use. Kotlin developers should use the following compiler argument to enforce correct usage: -Xjspecify-annotations=strict (this is the default starting with version 2.1.0 of the Kotlin compiler). ( Idfef8 , b/326456246 )
• Update Compose support for wide gamut and HDR colors when running on Android Q+. ( Icd8be , b/379135036 )
• Resource fonts that fail to load will now silently fall back to the default font, instead of the prior behavior of throwing an exception in measure. ( Ib6a49 )
• Fix focus lost when AndroidView is detached and attached. ( I53446 )
• Accept requestFocus() from beyond bound layout action. ( Ia8461 )

Внешний вклад

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

Версия 1.8.0-альфа06

• Changes Autofill manager to be an interface. ( I84914 , b/376080755 )
• Adds requestFocus(FocusDirection) to both focusRequester and FocusTargetModifierNode to allow focusing with a specific direction. ( I5d9ec , b/245755256 )
• FocusProperties.enter and FocusProperties.exit have been replaced with onEnter and onExit , using a receiver scope instead of FocusDirection parameter. ( I6e667 )
• Adding autofill support in text toolbar. ( Ie6a4c )
• API changes to Modifier.focusRestorer() ( I99c03 ):
  • parameter name changed to 'fallback'
  • parameter is now a FocusRequester and not a lambda
  • parameter is now non-NULL with Default as the default value
• Removing @Experimental annotation from autofill manager interface. The feature is still WIP targeting this release but we do not want to introduce @Expemiental API ( Id8398 )
• LocalHapticFeedback now provides a default HapticFeedback implementation when the Vibrator API indicates that haptics are supported. The following have been added to the HapticFeedbackType - Confirm , ContextClick , GestureEnd , GestureThresholdActivate , Reject , SegmentFrequentTick , SegmentTick , ToggleOn , ToggleOff , VirtualKey . Wear Compose long-clickable components such as Button , IconButton , TextButton , and Card now perform the LONG_PRESS haptic when a long-click handler has been supplied. ( I5083d )
• Removes OverscrollConfiguration and LocalOverscrollConfiguration , and adds rememberPlatformOverscrollFactory to create an instance of / customize parameters of the default overscroll implementation. To disable overscroll, instead of LocalOverscrollConfiguration provides null , use LocalOverscrollFactory provides null . To change the glow color / padding, instead of LocalOverscrollConfiguration provides OverscrollConfiguration(myColor, myPadding) , use LocalOverscrollFactory provides rememberPlatformOverscrollFactory(myColor, myPadding) . ( Ie71f9 , b/255554340 , b/234451516 )
• Removed the experimental GlobalAssertions API. It's intended use was to run accessibility checks, see enableAccessibilityChecks() for that purpose instead. ( I59322 )

Версия 1.8.0-альфа05

30 октября 2024 г.

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

Новые функции

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

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

Изменения API

• Modify Autofill interface to follow expect / actual structure. ( I22dce )
• Introduce CompositionLocal that can be used to modify the hue of Autofill's successful filling highlight. ( I32092 )
• Added Modifier.onRectChanged API which is an API that allows one to subscribe to the root/window/screen-relative position and size of a LayoutNode . The API solves many use cases that the existing onGloballyPositioned modifier does, however it does so with much less overhead and the API comes with facilities to debounce and throttle the callback per what one's use case demands. ( Id28c7 , b/372765423 , b/372757007 , b/372994338 )
• Expands Autofill manager to include commit() and cancel() APIs that help users save newly entered credentials. ( I2da00 )
• Introduces new AutofillManager interface that can be used to fine-tune users' Autofill journey and a isSemanticAutofillEnabled flag to turn on this new version of Autofill. ( I9d484 )
• Added Modifier.onRectChanged API which is an API that allows one to subscribe to the root/window/screen-relative position and size of a LayoutNode . The API solves many use cases that the existing onGloballyPositioned modifier does, however it does so with much less overhead and the API comes with facilities to debounce and throttle the callback per what one's use case demands. ( I3c8fa )
• Add in semantic properties and data types for extended Autofill support. ( I52c7d )
• All methods in AnnotatedString builder are non-experimental now ( Ia89c8 , b/261561823 )

Исправления ошибок

• Views embedded in compose can now receive rotary events if they are focused ( I4d53a , b/320510084 )
• Fixed an issue where various resource types wouldn't update on configuration changes ( Ia9b99 , b/352336694 )
• Addressed an issue that prevented TextField from functioning correctly when using the POBox Japanese Keyboard on certain older Sony devices. ( Ia9b99 , b/373743376 )
• Fixed problem with dialogs showing at bottom of the screen instead of centering ( Ia2ec , b/373093006 )
• Targeting API 35+ no longer forces dialogs to have decorFitsSystemWindows set to false. ( Ibc94 , b/364492593 )
• Fix crash when layers are moved between windows (eg dialog and main content) ( I675ba , b/330955281 )

Версия 1.8.0-альфа04

16 октября 2024 г.

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

Изменения API

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

Исправления ошибок

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

Исправления ошибок

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

Version 1.7.0-alpha08

1 мая 2024 г.

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

Изменения API

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

Исправления ошибок

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

Внешний вклад

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

Version 1.7.0-alpha07

17 апреля 2024 г.

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

Изменения API

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

Исправления ошибок

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

Version 1.7.0-alpha06

3 апреля 2024 г.

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

Новые функции

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

Изменения API

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

Version 1.7.0-alpha05

20 марта 2024 г.

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

Новые функции

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

Изменения API

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

Исправления ошибок

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

Внешний вклад

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

Version 1.7.0-alpha04

6 марта 2024 г.

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

Изменения API

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

Version 1.7.0-alpha03

February 21, 2024

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

Изменения API

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

Исправления ошибок

• Fixed a backwards compatibility issue with SemanticsPropertyReceiver.performImeAction and SemanticsActions.PerformImeAction . ( Ie0bb2 , b/322269946 )
• Layouts now issue an error while measuring when one returns an abnormally large size. This kind of error normally happens when the measurement uses maximum constraints directly without checking for Constraints.Infinity . The check will help developers find problems with the layout having the wrong size rather than in a layout that contains it. ( I339a9 )

Изменения API

• The DragAndDropTarget modifier now takes in the receiving DragAndDropTarget explicitly and has a lambda to opt into a drag and drop session. There are now two factory functions for a DragAndDropModifierNode . One for receiving transfers and one for transferring data ( I69481 )
• Updated maximumFlingVelocity to be represented as Float. Updated documentation to be more clear about the maximumFlingVelocity unity. ( I8adc7 )
• onDragAndDropStart in the DragAndDropModifierNode factory has been renamed to acceptDragAndDropTransfer . acceptsDragAndDropTransfer has been added to the dragAndDropTarget Modifier to accept from a drag and drop session. This lambda returns a viable DragAndDropTarget if interested in a drag and drop session. Other lambdas for processing drag events have been replaced by this. a DragAndDropTarget factory function has been added to receive from drag and drop sessions ( Iebf3a )

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

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

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

  The DragAndDropEventType has been removed ( I645b1 )

• Renamed PlatformTextInputModifierNode.runTextInputSession to establishTextInputSession . ( I03cd0 )

• Improves traversable node api names to make them more understandable. ( Ia4474 )

• Replace OriginalText by TextSubstitution . ( Ifa5a8 )

• Renamed PlatformTextInputModifierNode.textInputSession to runTextInputSession . ( Ie9c6b )

• The children of SubcomposeLayout (and layouts like LazyColumn based on it) which are retained to be reused in future are considered deactivated. New assertIsDeactivated() test API was introduced to test such nodes. The rests of the test apis will filter out deactivated nodes by default. ( I2ef84 , b/187188981 )

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

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

• FontStyle(int) constructor is deprecated, use FontStyle.Normal or FontStyle.Italic instead. ( I66610 )

• Renamed FontScalable interface to FontScaling ( Ie804a )

• Introduce SemanticsNodeInteraction.isDisplayed() and SemanticsNodeInteraction.isNotDisplayed() to check if a matched node is visible or not without also asserting on it. ( I2c196 , b/302100809 )
• Introduced a special Unspecified value for TextAlign , TextDirection , Hyphens and LineBreak fields of the ParagraphTextStyle to replace null . Because these classes are inline classes, by replacing nullable with the Unspecified, we avoid primitive type boxing. Constructors, getters and other methods in TextStyle and Paragraph style were updated to accept the mentioned parameters as non-null types. ( I4197e , b/299490814 )
• Add GoogleFont overload for reading a GoogleFont from XML. ( If8f59 )
• Made LoremIpsum PreviewParameterProvider an open class. ( I41bf5 , b/266918816 , b/300116360 )

• Add showSystemUi=true to PreviewScreenSizes definition ( Ib61d3 )

Изменения поведения

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

Version 1.6.0-alpha02

26 июля 2023 г.

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

Изменения API

• Added a service locator interface that can be implemented by implementors of Composition that allows an implementation of Composition that delegates to another composition delegate service lookups to the original Composition. This should not be called directy and is used to enable creating experimental APIs in the runtime that can be found from wrapped versions of the composer such as the UI module does. ( I296b9 )
• Completely redesigned PlatformTextInput* API. ( I6c93a , b/274661182 , b/267235947 , b/277380808 )
• SoftwareKeyboardController and LocalSoftwareKeyboardController are no longer experimental. LocalSoftwareKeyboardController is also now a proper CompositionLocal . ( I4c364 )

• Add experimental APIs for registering global assertions, for use by testing frameworks in the future. ( I12d77 )

Исправления ошибок

• AndroidView 's update callback's first invocation will now be defered until the view is attached, instead of running when the composition that introduces the AndroidView is applied. This fixes a bug where the update callback wouldn't be invalidated if a state it read was changed immediately by an effect. ( Ie9438 , b/291094055 )

Version 1.6.0-alpha01

21 июня 2023 г.

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

Новые функции

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

Behavior Change: includeFontPadding is now false by default in Compose

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

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

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

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

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

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

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

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

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

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

Новые функции

• Modifier.Node Delegation Improvements Added an enhanced ability to delegate to other Modifier.Node instances from a DelegatingNode . This can be done with the delegate and undelegate APIs. Prior to this change, every API from the delegating node needed to be delegated explicitly to the delegated node. After this change, node interfaces will get delegated implicitly unless the DelegatingNode is explicitly overriding them. ( 67352bc )

Изменения API

• Introduce NestedScrollModifierNode , a NestedScroll Modifier.Node that can be delegated to. ( I69513 )

Новые функции

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

Изменения API

• New default intermediateMeasurePolicy that reuses measure policy from lookahead pass allows SubcomposeLayout subtypes without conditional slots such as Scaffold , TabRow , and BoxWithConstraints to work with lookahead by default. ( Id84c8 )
• The recomposer created for an Android window will now only block calls to withFrameNanos instead of all composition when it receives an ON_STOP notification. This means windows associated with stopped activites will continue to recompose for data changes but the animations, or any other caller of withFrameNanos , will block. ( Id9e7f , b/240975572 )
• Changes motionEventSpy to stable. ( Ic5ec4 , b/261560988 )
• Added public TextRange.constrain method. ( I97912 )

• UrlAnnotation s in AnnotatedString s can now be opened via accessibility services like TalkBack . ( If4d82 , b/253292081 )
• Added an API to intercept hardware keys before they are sent to the soft keyboard ( I4f4c6 , b/186800395 )
• Added the InsertTextAtCursor semantics action for text fields. ( I11ed5 )
• Text-related test actions (eg performTextInput ) will now request focus directly, using the semantics action, instead of clicking on the field. ( I6ed05 )

Исправления ошибок

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

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

Изменения API

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

Important changes since 1.3.0

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

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

Изменения API

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

Исправления ошибок

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

Изменения API

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

Версия 1.4.0-альфа03

7 декабря 2022 г.

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

Изменения API

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

Исправления ошибок

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

Обновления зависимостей

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

Версия 1.4.0-альфа02

9 ноября 2022 г.

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

Изменения API

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

24 октября 2022 г.

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

Изменения API

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

Modifier Node Refactor

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

Сводка изменений

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.

Риск

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.

Изменения API

• Introduce a new experimental API called TextMeasurer that enables arbitrary text layout computation that creates identical results to BasicText , independent from Compose runtime. ( I17101 )
• Add mapTree to SlotTree.kt . This allows tools to inspect the SlotTree without making an in memory copy first like asTree does. For the Layout Inspector this gives a performance improvement of about a factor 10. ( I5e113 )
• Changed Compose Preview to be stored in binary output files, in order to allow developers to write and reuse MultiPreview annotations from libraries. ( I85699 , b/233511976 )

Исправления ошибок

• 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 ( Icea9d , b/216582726 , b/223440806 , b/227709803 )
• Fix NPE caused by AnnotatedString.toUpperCase when annotations are present. ( I0aca2 , b/210899140 )

Изменения API

• New LookaheadLayout that supports a lookahead pass before the actual measure/layout. This allows a pre-calculation of the layout when it changes, while permitting the post-lookahead measure/layout to use the pre-calculated size/position to animate the size and positions towards the target. SubcomposeLayouts are not yet supported, but will be in an upcoming release. ( I477f5 )
• Add optional alpha parameter to Brush flavor of TextStyle and SpanStyle to modify opacity of the whole Text . ( Ic2fac , b/234117635 )
• Introduced the UrlAnnotation annotation type and associated methods to support TalkBack link support in AnnotatedString s. ( I1c754 , b/231495122 )
• Moving utility functionality to runtime ( I4f729 )

Исправления ошибок

• TextLayoutResult.getLineForOffset does not throw. ( Idc5d6 , b/235876324 )

Изменения 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 )

Изменения API

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

Исправления ошибок

• 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 )

• ViewCompositionStrategy.DisposeOnDetachedFromWindowIfNotInPoolingContainer has been renamed to DisposeOnDetachedFromWindowOrReleasedFromPool to better reflect that when disposals do occur, rather than simply when they do not occur. ( If15ca )

Версия 1.2.0-beta01

androidx.compose.ui:ui-*:1.2.0-beta01 is released. Version 1.2.0-beta01 contains these commits.

Новые функции

• This is the first beta release of 1.2!

Изменения API

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

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

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

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

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

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

  К:

  @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 )

Исправления ошибок

• 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 )

Внешний вклад

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

Version 1.2.0-alpha08

20 апреля 2022 г.

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

Изменения 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 апреля 2022 г.

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

Изменения 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 )

Исправления ошибок

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

Version 1.2.0-alpha06

23 марта 2022 г.

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

Изменения 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 )

Исправления ошибок

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

Внешний вклад

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

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

Исправления ошибок

• 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 )

Внешний вклад

• Updated to use Kotlinx coroutines 1.6.0 ( I3366d )

Version 1.2.0-alpha04

23 февраля 2022 г.

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

Изменения 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 )

Исправления ошибок

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

Version 1.2.0-alpha03

9 февраля 2022 г.

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

Изменения API

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

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

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

• FontFamilyResolver is now available via LocalFontFamilyResolver.current

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

• Paragraph and MultiParagraph now take FontFamily.Resolver

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

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

• Support for preloading fonts via FontFamilyResolver.preload

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

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

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

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

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

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

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

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

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

• 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 )

• 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 )

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

Important changes since 1.0.0

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

Version 1.1.0-rc03

Исправления ошибок

• Fixed a bug that caused missing accessibility scroll actions ( I7cbfb )
• SemanticsNodeInteraction.captureToImage() will now also work if HardwareRenderer.isDrawingEnabled() is false , by enabling it for the duration of the call ( Idf3d0 )

Version 1.1.0-beta04

1 декабря 2021 г.

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

Новые функции

• Updated to be compatible with Kotlin 1.6.0

Изменения 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 )

Исправления ошибок

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

Version 1.1.0-beta03

17 ноября 2021 г.

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

Изменения 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 )

Исправления ошибок

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

Version 1.1.0-beta02

3 ноября 2021 г.

androidx.compose.ui:ui-*:1.1.0-beta02 is released. Version 1.1.0-beta02 contains these commits.

Изменения API

• Added experimental BringIntoView API that lets you send a request to parents so that they scroll to bring an item into view ( Ib918d , b/195353459 )
• New animation APIs for supporting tooling. Specifically, they allow tooling to inspect the animations & their configurations in a Transitions. ( I4116e )

Внешний вклад

• Added Modifier.pointerHoverIcon ( I95f01 )

Версия 1.1.0-beta01

androidx.compose.ui:ui-*:1.1.0-beta01 is released. Version 1.1.0-beta01 contains these commits.

Изменения API

• Added experimental BringIntoView API that lets you send a request to parents so that they scroll to bring an item into view ( Ib918d , b/195353459 )
• New animation APIs for supporting tooling. Specifically, they allow tooling to inspect the animations & their configurations in a Transitions. ( I4116e )

Version 1.1.0-alpha06

13 октября 2021 г.

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

Изменения 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 )

Исправления ошибок

• 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 сентября 2021 г.

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

Изменения 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 )

Исправления ошибок

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

Version 1.1.0-alpha04

15 сентября 2021 г.

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

Изменения 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 )

Исправления ошибок

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

Version 1.1.0-alpha03

1 сентября 2021 г.

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

Новые функции

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

Изменения 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 )

Исправления ошибок

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

Version 1.1.0-alpha02

18 августа 2021 г.

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

Изменения 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 )

Исправления ошибок

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

Версия 1.1.0-альфа01

4 августа 2021 г.

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

Изменения 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 )

Исправления ошибок

• 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 )

Новые функции

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

Изменения 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 )

Изменения поведения

• 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 )

Version 1.0.0-beta09

16 июня 2021 г.

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

Изменения 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 )

Исправления ошибок

• 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
• androidx.compose.material
• androidx.compose.material-ripple
• androidx.compose.runtime
• androidx.compose.ui
• androidx.compose.ui.geometry
• androidx.compose.ui.graphics
• androidx.compose.ui.text
• androidx.compose.ui.text
• androidx.compose.ui.unit
• androidx.compose.ui.util

What are profile rules?

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

• A method rule will have the following pattern:

  <FLAGS><CLASS_DESCRIPTOR>-><METHOD_SIGNATURE>
  

• And a class rule will have the following pattern:

  <CLASS_DESCRIPTOR>
  

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

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

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

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

What do the rules do?

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

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

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

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

Как это работает?

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

Version 1.0.0-beta08

2 июня 2021 г.

androidx.compose.ui:ui-*:1.0.0-beta08 is released. Version 1.0.0-beta08 contains these commits.

Изменения API

• NestedScrollSource enum is replaced by an inline class. ( Ie321b , b/187055290 )
• FocusManager.clearFocus(forcedClear = true) is renamed to FocusManager.clearFocus(force = true) ( Ia0c41 )
• Refactored enum usages to inline classes to avoid issues with exhaustive when statements when new enum values are added. ( I2b5eb )
• Remove @ExperimentalComposeUiApi from PopupProperties . ( I01fa6 )
• PointerType was changed from an enum to an inline class ( If5058 )
• ContentDescription and Text semantics properties are no longer single values but lists. This enables to merge them as they are instead of concatenations. Also provided better testing APIs to utilize these changes ( Ica6bf , b/184825850 )
• Modifier.focusModifier() is deprecated and replaced by Modifier.focusTarget() ( I6c860 )
• Modifier.onSizeChanged() and Modifier.onGloballyPositioned() are not inlined functions anymore ( I727f6 , b/186109675 )
• KeyboardType enum is replaced by an inline class. ( I73045 , b/187055290 )
• Replaced FocusState enum with a FocusState interface ( Iccc1a , b/187055290 )
• ImeAction enum is replaced by an inline class. ( I18be5 , b/187055290 )

• TextUnitType is an inline class now. ( I4cba9 )
• AnnotatedString.withAnnotation functions are now ExperimentalTextApi instead of ExperimentalComposeApi. ( I0cd0a )
  • TextUnit constructor with TextUnitType is now ExperimentalTextApi instead of ExperimentalComposeApi.

Исправления ошибок

• 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 мая 2021 г.

androidx.compose.ui:ui-*:1.0.0-beta07 is released. Version 1.0.0-beta07 contains these commits.

Изменения API

• Added ViewRootForInspector interface for use in inspector ( Ib70df )
• SubcomposeLayoutState now supports setting count of reusable slots. The layout will keep up to this count slots active instead of disposing them in order to reuse the slot next time we need a new one ( Ieb981 )
• KeyEventType enum is replaced by an inline class. ( Id670a , b/187055290 )
• 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 )

Изменения 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>

  • ( 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 )

  • 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

  • Composer.collectKeySourceInformation has been removed. It is no longer necessary.
  • isJoinedKey, joinedKeyLeft, and joinedKeyRight methods have been removed. They are no longer necessary.

  • ( 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 )

  • 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.

• 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 )

  • ( I99c19 )
• Tests in which Compose is used in hierarchies that are added/removed directly to the WindowManager are now more stable. ( Ie81ed , b/175765614 )

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 )

Исправления ошибок

• Added a function reference parameter type ( I5e1bd )
• Add transformed bounds to InspectorNode ( Ice42f )

Исправления ошибок

• 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 )

Критические изменения

• 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 )

Изменения API

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

Изменения 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 )
• Modifier.focusObserver is deprecated. Use Modifier.onFocusChanged or Modifier.onFocusEvent instead ( I30f17 , b/168511863 , b/168511484 )

• 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 )

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

Исправления ошибок

• 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 )

• 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 )

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 )

Версия 1.0.0-альфа06

28 октября 2020 г.

androidx.compose.ui:ui-*:1.0.0-alpha06 is released. Version 1.0.0-alpha06 contains these commits.

Изменения 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 )
• Fix Rtl Handle Position. ( I6e1e0 )
• Refactored DrawScope and ContentDrawScope to be interfaces instead of abstract classes
  • Created CanvasDrawScope implementation of DrawScope
  • Refactored implementations of DrawScope to use CanvasScope instead
  • Created DrawContext to wrap dependencies for DrawScope
  • Removed deprecated methods on DrawScope ( I56f5e )
• Breaking change: removed the return value from PointerInputFilter.onPointerEvent(...) given that the only value that should be able to be changed in pointer events is consumption data. Instead of returning data from PointerInputFilter.onPointerEvent(...) , now you can just mutate the consumption data of the PointerEvents passed in. ( I6acd0 )
• MeasureScope and IntrinsicMeasureScope were made interfaces. ( I1a087 , b/170461665 )
• The merge function for AlignmentLine was hidden. ( I9da1a , b/170612900 , b/170611568 )

• Popups and dialogs now inherit FLAG_SECURE from parent Window. Also added option to configure this explicitly ( I64966 , b/143778148 , b/143778149 )

• Consumption data is now mutable. Also calls to extension functions that do consumption now no longer return a new PointerInputChange, but instead mutate the provided PointerInputChange.

  This is the first step in a 2 step process to make PointerEvent data mutable such that other pointer data cannot be edited by user code. The second step will be to remove the List<PointerInputChange> return type from PointerInputFilter.onPointerEvent(...) . ( Id067e )

• Disable Selection in Text, and a Demo. ( Ie7e97 )

• Made onGloballyPositioned an inline function ( I15830 )

• OnPositionedModifier is renamed to OnGloballyPositionedModifier and onPositioned() is renamed to onGloballyPositioned(). ( I587e8 , b/169083903 )

• The hasPendingMeasureOrLayout property was added to Owner, telling whether the Owner has any pending layout work. ( I3d9f8 , b/169038599 )

• Added API to programmatically clear focus ( Ie1dc2 , b/161487952 )

• Changes to Size

  • Removed Size.getFlipped
  • Removed Size.rem

• The scope parameter within AnnotatedString.Builder.addStringAnnotation is renamed to tag for API consistency. ( I7c8cb )

Исправления ошибок

• The scrolling performance of LazyColumn/Row is improved by doing less work in subcomposition on every scroll. The new hasInvalidations() method was added for Composition class. hasPendingChanges() method from Recomposer was renamed to hasInvalidations() ( Ib2f32 , b/168293643 , b/167972292 , b/165028371 )
• 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 )

• Made FocusManager private. ( I7872f )

• Updated implementation to create a dedicated DrawCacheModifier implementation instead of adding optional properties on DrawModifier.

  Updated documentation for various methods ( Ibd166 )

• Make TextRange inline to avoid object creation. ( Id034b )

  • Migrated various RoundRect extension functions to be properties instead
  • ( I8f5c7 , b/168762961 )
• 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 )

• Removed onInvalidate() from Owner -- OwnedLayer handles invalidation. ( Ica72b , b/162061312 )

• Removed operator methods on Size API that consume Offset parameters. The result of these operations is unclear and the type of result is unexpected for these. Ex. should size - offset return an offset or a size result with the difference?

  Also removed deprecated methods on Size class. ( Iec902 , b/166514214 )

Исправления ошибок

• Uptime and Velocity are now inline classes ( I48f4a )
• Duration is now an inline class ( I565eb )
• Add a callback to notify Owner when layoutnode bounds change. ( Ic40b3 )

  Removed deprecated companion methods on Rect in favor of function constructors.

  Added tests to verify methods in Rect.kt ( I08460 , b/165822356 )

Исправления ошибок

• Added MutableRect, a rectangle that can be modified. ( I71bd2 , b/160140398 )
• Matrix4 was replaced with Matrix. All other parts of vectormath package have been removed. ( Ibd665 , b/160140398 )

• The calling convention for composable functions has changed. This is a binary breaking change. All libraries must be recompiled to work with this version of the compose compiler plugin.

  This change does not create a source level breaking change as the only APIs that have changed are compiler APIs that have an explicit opt in. ( I7afd2 , b/158123185 )

• Fixed crash that could occur when dispatch to a PointerInputFilter could cause the PointerInputFilter to be synchronously removed. ( I58f25 )

Изменения API

• emitView was deprecated. Use AndroidView instead if possible for emitting Views inside Compose. Note that composing Views and ViewGroups directly will not be supported in the future unless these are leaves in the composition tree, case when this can be achieved using AndroidView. ( I29b1e , b/163871221 )
• FocusState2 is deprecated and replaced by FocusState ( Ia8b79 , b/160822876 , b/160923332 )
