Фонд «Композиции»

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.foundation:foundation:1.9.4"
}

android {
    buildFeatures {
        compose true
    }

    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.15"
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

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

android {
    buildFeatures {
        compose = true
    }

    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.15"
    }

    kotlinOptions {
        jvmTarget = "1.8"

• Флаг isWindowInsetsModifierLocalNodeImplementationEnabled был удален ( I15e8f , b/440964232 )
• Предоставьте модификатор scrollableArea() , который можно использовать, чтобы сделать компонент прокручиваемым с поведением обрезки содержимого по его границам и автоматической обработки направления прокрутки содержимого на основе ориентации, RTL и флага reverseScrolling . ( I9471b , b/316559454 )

Версия 1.10.0-альфа03

10 сентября 2025 г.

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

Изменения API

• Удаляет ComposeFoundationFlags.isNonComposedClickableEnabled ( I0dfc0 , b/406228525 )
• 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 )
• ScrollState.value отмечено как свойство @FrequentlyChangingValue . ( I4723d )
• Представлен LazyLayoutKeyIndexMap и фабрика для реализации по умолчанию. ( I4fd0c , b/415038029 )

Исправления ошибок

• Столбец и строка теперь правильно передают фактический размер элемента в Modifier.align , что решает проблему, из-за которой пользовательская реализация Modifier.align получала неверное значение 0. ( I8194f , b/439716351 )

Версия 1.10.0-альфа02

27 августа 2025 г.

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

Изменения API

• Удален флаг isFlingContinuationAtBoundsEnabled . ( I6b84f )
• Удален флаг isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled . ( I62380 )
• Удален флаг isOnScrollChangedCallbackEnabled . ( I667dc )
• Удален флаг isAutomaticNestedPrefetchEnabled . ( I4f416 )
• Удален флаг DragGesturePickUpEnabled . ( Ib8500 )
• Представлен API ScrollIndicatorState для представления состояния полосы прокрутки ( I5e229 )

Исправления ошибок

• Исправлена ​​ошибка, из-за которой использование Modifier.anchoredDraggable не приводило к вызову confirmValueChange . ( Iff7cc )

Версия 1.10.0-альфа01

13 августа 2025 г.

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

Изменения API

• Обновить стратегию предварительной выборки Pager, чтобы использовать окно кэша вместо одного элемента по умолчанию в направлении прокрутки. Теперь начальная предварительная выборка в Pager включена по умолчанию и будет основана на размере окна, равном одному окну просмотра, то есть мы попытаемся заполнить один участок просмотра предварительно выбранными элементами. Элементы также будут храниться дольше. ( I4d45e , b/292136289 )
• Добавлен флаг ComposeFoundationLayoutFlags.isWindowInsetsOptimizationEnabled , позволяющий отключить оптимизацию производительности WindowInsets , если новая реализация приведет к изменению поведения. ( I8e912 )
• SnapFlingBehavior теперь допускает превышение значений спецификаций анимации привязки во время привязки. Это позволяет, например, спецификации упругой пружины в качестве snapAnimationSpec создавать упругую анимацию привязки. Значения превышения значений по-прежнему игнорируются при выполнении подхода с использованием спецификации привязки. ( I373c2 )
• 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 )
• 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 ).
• Обновлён DragGestureNode для использования необработанного ввода указателя вместо приостановки ввода указателя для оптимизации. Изменения добавлены после флага isNonSuspendingPointerInputInDraggableEnabled ( I0fa4b ).
• Некоторые API AnchoredDraggable аннотированы с помощью @FrequentlyChangingValue . offset , requireOffset и progress часто меняются и не должны считываться в процессе композиции. Вместо этого обращайтесь к этим значениям из макета и отрисовывайте фазы, эффекты или иным образом вне процесса композиции. ( I05539 )
• Удалены флаги isOnScrollChangedCallbackEnabled , isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled , isFlingContinuationAtBoundsEnabled , isAutomaticNestedPrefetchEnabled , DragGesturePickUpEnabled , isPointerInteropFilterDispatchingFixEnabled , isNestedScrollInteropPostFlingFixEnabled , isNestedScrollDispatcherNodeFixEnabled ( I36c18 ).
• Введен CompositionLocal , который можно использовать для изменения кисти подсветки успешного заполнения Autofill. ( I52329 )
• Добавлена ​​настраиваемая область фокусировки в FocusProperties . Теперь вы можете определить собственную область фокусировки вместо использования ограничивающего прямоугольника фокусируемого элемента по умолчанию. Эта информация используется системой перемещения фокуса и логикой удержания в поле зрения прокручиваемых контейнеров. ( Id6555 , b/368378073 )
• 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 )
• 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 )
• Добавляет косвенные входные события и способ указания осей координат, используемых для прокрутки. ( I58e7c )
• Добавляет новый API WindowInsets.cutoutPath для получения пути к вырезу на дисплее ( Ib90b1 , b/279636456 ).
• Флаг isWindowInsetsDefaultPassThroughEnabled был удален, что по умолчанию отключает потребление WindowInsets, так что дочерние представления могут получать WindowInsets по умолчанию. ( I888e0 , b/412469666 )

Исправления ошибок

• isNonSuspendingPointerInputInDraggableEnabled на данный момент следует отключить. ( Ia41c4 )
• Перемещение minSdk по умолчанию из API 21 в API 23 ( Ibdfca , b/380448311 , b/435705964 , b/435705223 )
• Обновлена ​​документация minPosition/maxPosition DraggableAnchors с целью указать, что эти API должны возвращать Float.NaN в соответствии с другими API DraggableAnchors . ( I0460a )
• Исправлена ​​ошибка, из-за которой DraggableAnchors#closestAnchor аварийно завершал работу, если якоря были пустыми ( I4e646 ).
• Улучшения производительности для DraggableAnchors ( If4065 , I0460a )
• TextFieldState.edit { } больше не очищает историю отмены. Вместо этого создаётся отдельная запись отмены. Если требуется очистить стек отмены после вызова edit , используйте TextFieldState.undoState.clearHistory() . ( I12c14 )
• Добавлена ​​поддержка двойного нажатия для выбора слова в перегрузке SelectionContainer и BasicTextField(value, onValueChange) . ( Ibb06a )
• Исправлена ​​небольшая ошибка, делающая AutoboxingStateValuePropertyDetector совместимым как с K1, так и с K2 ( Ie81c1 ).
• Запросы requestRectangleOnScreen , отправляемые AndroidViews, теперь корректно передаются в Compose. Это помогает таким представлениям, как EditText , оставаться на экране при взаимодействии с ними. ( Ibbf4c )
• Column и Row теперь правильно передают фактический размер элемента в Alignment.Vertical.align и Alignment.Horizontal.align , что решает проблему, из-за которой пользовательские реализации выравнивания получали неверное значение 0. ( I3e460 , b/349722072 )

Исправления ошибок

• Исправлен сбой, возникающий при использовании LazyLayoutCacheWindow в LazyLists ( c39f5f3 ).

Версия 1.9.0

13 августа 2025 г.

Выпущена версия androidx.compose.foundation:foundation-*:1.9.0 . Версия 1.9.0 содержит следующие коммиты:

Важные изменения с версии 1.8.0

• 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: перегрузки clickable , combinedClickable , selectable , toggleable и triStateToggleable без параметра Indication теперь поддерживают только экземпляры IndicationNodeFactory , предоставленные с помощью LocalIndication . Это изменение вступит в силу при перекомпиляции использований этих модификаторов с использованием этой версии Compose. Бинарные/транзитивные зависимости не затронуты. Если вы предоставляете устаревшую реализацию Indication для LocalIndication и используете эти API, это приведет к сбою во время выполнения. Это изменение поведения необходимо для повышения производительности и позволяет функциям Composable, использующим эти модификаторы, пропускать рекомпозицию. Вы можете использовать ComposeFoundationFlags.isNonComposedClickableEnabled=false , чтобы временно отказаться от этого изменения поведения и разрешить обновление Compose без блокировки при этой миграции. Этот флаг будет удален после одного стабильного выпуска. Для решения этой проблемы перенесите все устаревшие реализации Indication на использование IndicationNodeFactory . Вы также можете использовать перегрузки с явным параметром Indication — эти перегрузки будут продолжать поддерживать не- IndicationNodeFactory экземпляры Indication, хотя это не рекомендуется по соображениям производительности. ( I6bcdc , b/316914333 )
• Добавлено isFlingCancellationWithNestedScrollFixEnabled для исправления проблемы с распространением мелькания при вложенной прокрутке. В этом CL мы восстанавливаем поведение продолжения мелькания, удалённое в I9326a . Мы по-прежнему будем отменять анимацию мелькания при удалении дочернего элемента из композиции. ( I467f4 , b/405910180 , b/419049142 , b/416784125 )
• Повторно добавлено использование scrollAnimationSpec в ContentInViewNode . Это поведение было удалено во время прекращения поддержки scrollAnimationSpec , что привело к нарушению вариантов использования. ( I1436a , b/403301605 )
• Стабилизированный LazyLayout ( If5db4 ), LazyLayoutPrefetchState и его методы планирования schedulePrecomposition и schedulePrecompositionAndPremeasure ( I4362f , b/252853717 ) и LazyLayoutItemProvider ( Icce09 , b/261565751 )
• Разрешить Compose вызывать ViewTreeObserver.OnScrollChanged . Это поведение реализовано с помощью флага isOnScrollChangedCallbackEnabled . Мы также добавили функцию расширения DelegatableNode dispatchOnScrollChanged . ( I34b9d , b/238109286 )
• Представлены Modifier.scrollable2D , Scrollable2DState и сопутствующие API для создания состояний. Также представлены общие функции расширения прокрутки. ( Ic61c8 , b/214410040 )
• PrefetchScheduler и настройка были объявлены устаревшими в пользу внутренней реализации, которая выполняет всю работу автоматически. ( I3a9a6 , b/420551535 )
• TextFieldState.edit { } больше не очищает историю отмены. Вместо этого создаётся отдельная запись отмены. Если требуется очистить стек отмены после вызова редактирования, используйте TextFieldState.undoState.clearHistory() . ( I12c14 )
• Контекстное меню и панель инструментов выбора теперь поддерживают смарт-элементы (умный выбор)
• Добавлен стилизованный текст OutputTransformation , позволяющий стилизовать вывод TextField с использованием перегрузки state .
• TextField : поддержка контекстного меню (меню, вызываемое правой кнопкой мыши).
• Текст, скопированный из нескольких текстовых компоновщиков в SelectionContainer , теперь будет иметь разделитель строк \n, добавленный между текстом, поступающим из отдельных текстовых компоновщиков. ( I25332 , b/285036739 )
• Представить API для создания пользовательских маркированных списков через AnnotatedString ( I1d066 , b/383269496 , b/139326648 )
• Перегрузка state BasicTextField будет сохранять курсор прокрученным в поле зрения при изменении его размера. ( I0eb41 , b/406187741 )
• Критическое изменение: узлы модификаторов background и border 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 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.foundation:foundation-*:1.9.0-rc01 . Версия 1.9.0-rc01 содержит следующие коммиты .

Исправления ошибок

• TextFieldState.edit { } больше не очищает историю отмены. Вместо этого создаётся отдельная запись отмены. Если требуется очистить стек отмены после вызова edit , используйте TextFieldState.undoState.clearHistory() . ( I12c14 )

Версия 1.9.0-beta03

16 июля 2025 г.

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

Исправления ошибок

• Исправлена ​​регрессионная ошибка, нарушавшая поведение закрепленных заголовков в ленивых сетках при предоставлении пустого содержимого заголовка. ( e3e3400 )

Версия 1.9.0-beta02

2 июля 2025 г.

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

Новые функции

• Поддержка смарт-элементов в контекстном меню и панели инструментов выбора.

Изменения API

• Исправлена ​​ошибка, из-за которой некоторые аппаратные клавиатуры или пульты дистанционного управления телевизорами не перемещали курсор в новых TextFields с помощью клавиш управления курсором, а вместо этого переключали фокус на другой компонуемый элемент. Добавлен ComposeFoundationFlag.isTextFieldDpadNavigationFixEnabled , позволяющий временно отключить это исправление, если оно приводит к неустранимым нежелательным последствиям. ( Ie1922 )

Исправления ошибок

• Исправлена ​​ошибка, из-за которой закрепленные заголовки не сохранялись при наличии закрепленного элемента. ( I9198d , b/385006133 )
• TextObfuscationMode.RevealLastTyped теперь соответствует системной настройке «TEXT_SHOW_PASSWORD». ( I41c0c )
• Исправлена ​​ошибка, из-за которой BasicTextField ошибочно отображал предупреждение «Данные вставлены из буфера обмена» при первом открытии текстовой панели инструментов. ( I5fda2 )

Версия 1.9.0-beta01

18 июня 2025 г.

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

Критические изменения

• Узлы модификаторов background и border 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 при добавлении нового узла между текущим и целевым узлами. 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

• Переименуйте Modifier.addTextContextMenuComponents в appendTextContextMenuComponents . ( I4c43f )
• Удалена AnnotatedOutputTransformation и перенесены функции addStyle в TextFieldBuffer . addStyle по-прежнему можно вызывать только из OutputTransformation . ( I9930a , b/417991824 )
• Clickable переписан так, чтобы не использовать ввод указателя приостановки для оптимизации. Эта функция включается флагом ComposeFoundationFlags.isNonSuspendingPointerInputInClickableEnabled , который можно отключить при обнаружении ошибки в новой реализации ( I85b65 ).
• Добавлено свойство isFlingCancellationWithNestedScrollFixEnabled для исправления проблемы с распространением мелькания при вложенной прокрутке. В этом CL мы восстанавливаем поведение продолжения мелькания, удалённое в aosp/3260391 . Мы по-прежнему будем отменять анимацию мелькания в случае удаления дочернего элемента из композиции. ( I467f4 , b/405910180 , b/419049142 , b/416784125 )
• WindowInsetsRulers : значение rulersIgnoringVisibility изменено на максимальное. Функция getDisplayCutoutBounds() теперь является функцией расширения PlacementScope . WindowInsetsAnimationProperties изменена на WindowInsetsAnimation , а getAnimationProperties() — на getAnimation() . ( I3816f )
• 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 )

Исправления ошибок

• Повторно добавлено использование scrollAnimationSpec в ContentInViewNode . Это поведение было удалено во время прекращения поддержки scrollAnimationSpec , что привело к нарушению вариантов использования. ( I1436a , b/403301605 )

Версия 1.9.0-альфа04

4 июня 2025 г.

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

Изменения API

• PrefetchScheduler и настройка были объявлены устаревшими в пользу внутренней реализации, которая выполняет всю работу автоматически. ( I3a9a6 , b/420551535 )
• Обновлен Scrollable2DState для использования смещения в методе canScroll вместо угла. ( I28694 , b/417268474 )
• Заменен addAnnotation в AnnotatedOutputTransformation на addStyle . ( I91c6f , b/417991824 )
• Стабилизированный LazyLayout . ( If5db4 )
• Стабилизирован пустой конструктор для LazyLayoutPrefetchState и его методы планирования schedulePrecomposition и schedulePrecompositionAndPremeasure . ( I4362f , b/252853717 )
• В Android представлен ProcessTextKey используемый для пунктов контекстного меню, которые добавляются для действий намерения PROCESS_TEXT . ( If0ac4 )
• API контекстного меню открыты. Доступны Modifier.addTextContextMenuComponents и Modifier.filterTextContextMenuComponents для добавления и удаления элементов в контекстном меню. Также открыты следующие элементарные API для создания настраиваемого контекстного меню:
  • TextContextMenuProvider
  • TextContextMenuDataProvider
  • TextContextMenuData
  • TextContextMenuComponent
  • LocalTextContextMenuDropdownProvider
  • LocalTextContextMenuToolbarProvider ( I1b7b0 )
• Сделать LazyLayoutItemProvider стабильным ( Icce09 , b/261565751 )
• Добавлены функции интеллектуального выделения текста в Android, которые можно включать/отключать с помощью ComposeFoundationFlags.isSmartSelectionEnabled . Также доступен статический compositionLocal LocalTextClassifierCoroutineContext , который можно использовать для указания CoroutineContext , в котором запускается задание TextClassification . ( I1dbaa , b/139321320 )

Версия 1.9.0-альфа03

20 мая 2025 г.

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

Изменения API

• Добавлен AnnotatedOutputTransformation , который позволяет добавлять аннотации в TextField перед рендерингом. ( Ibc6f0 , b/389978748 )
• Внедрите LazyLayoutMeasurePolicy и сделайте LazyLayoutMeasureScope стабильным. ( I8c5df , b/252853717 )
• BasicSecureTextField теперь поднимает ScrollState своего внутреннего BasicTextField . ( I6e576 )
• 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 )
• Введена перегрузка detectDragGestures , которая имеет функцию управления отклонением касания и блокировкой ориентации. ( Iadb0d )
• 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 )

Исправления ошибок

• Текст, скопированный из нескольких текстовых компоновщиков в SelectionContainer , теперь будет иметь разделитель строк \n добавленный между текстом, поступающим из отдельных текстовых компоновщиков. ( I25332 , b/285036739 )

Версия 1.9.0-альфа02

7 мая 2025 г.

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

Изменения API

• Исправлено, как изменения ввода указателя добавляются в VelocityTracker в DragGestureNode . Это можно контролировать с помощью нового флага isOffsetPositionBeforeAddingToVelocityTrackerEnabled . ( Ic7992 , b/292556787 , b/236451818 )
• Сделать await[Vertical/Horizontal]PointerSlopOrCancellation публичным ( I6968b , b/298903681 )
• AbstractComposeView.consumeWindowInsets теперь по умолчанию имеет значение false. При установке значения false свойство WindowInsets автоматически корректируется с учетом размера и положения дочернего элемента, поэтому больше нет необходимости устанавливать его по умолчанию равным true. Это устраняет проблему, из-за которой дочерние представления не получали обновления WindowInsets по умолчанию. Разработчики могут отказаться от обновления, изменив экспериментальное значение ComposeFoundationLayout.isWindowInsetsDefaultPassThroughEnabled на true или, что предпочтительнее, установив значение true для AbstractComposeView.consumeWindowInsets во всех экземплярах представления Compose. ( I6fa0a , b/411868840 )

Внешний вклад

• Исправлен сбой пейджера при чрезвычайно больших значениях beyondViewportPageCount ( Idb2db ).

• 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: перегрузки clickable , combinedClickable , selectable , toggleable и triStateToggleable без параметра Indication теперь поддерживают только экземпляры IndicationNodeFactory , предоставленные с помощью LocalIndication . Это изменение вступит в силу при перекомпиляции использований этих модификаторов с использованием этой версии Compose. Бинарные/транзитивные зависимости не затронуты. Если вы предоставляете устаревшую реализацию Indication для LocalIndication и используете эти API, это приведет к сбою во время выполнения. Это изменение поведения необходимо для повышения производительности и позволяет функциям Composable, использующим эти модификаторы, пропускать рекомпозицию. Вы можете использовать ComposeFoundationFlags.isNonComposedClickableEnabled=false , чтобы временно отказаться от этого изменения поведения и разрешить обновление Compose без блокировки при этой миграции. Этот флаг будет удален после одного стабильного выпуска. Для решения этой проблемы перенесите все устаревшие реализации Indication на использование IndicationNodeFactory . Вы также можете использовать перегрузки с явным параметром Indication — эти перегрузки будут продолжать поддерживать не- IndicationNodeFactory экземпляры Indication, хотя это не рекомендуется по соображениям производительности. ( I6bcdc , b/316914333 )

Изменения API

• Представить API для создания пользовательских маркированных списков через AnnotatedString ( I1d066 , b/383269496 , b/139326648 )
• Разрешить Compose вызывать ViewTreeObserver.OnScrollChanged . Это поведение реализовано с помощью флага isOnScrollChangedCallbackEnabled . Мы также добавили функцию расширения DelegatableNode dispatchOnScrollChanged . ( I34b9d , b/238109286 )
• Для проектов, выпущенных с использованием Kotlin 2.0, требуется использование KGP 2.0.0 или более поздней версии ( Idb6b5 ).
• Добавлена ​​поддержка проверки линта для TextFieldState , чтобы убедиться, что он запоминается при составлении. Рассмотрите возможность использования rememberTextFieldState вместо него. ( I53d74 )
• Добавлена ​​поддержка проверки линта для FocusRequester , чтобы убедиться, что он запомнен внутри композиции ( I6bf91 ).
• Добавлена ​​поддержка проверки линта для BringIntoViewRequester , чтобы убедиться, что он запомнен внутри композиции. ( Ibfba6 )
• Введены области действия для вызовов schedulePrefetch в стратегиях сеток и списков для согласования с возможностями LazyListPrefetchState по предоставлению информации о размере и индексе. ( Iad80c )
• Критическое изменение: перегрузки clickable , combinedClickable , selectable , toggleable и triStateToggleable без параметра Indication теперь поддерживают только экземпляры IndicationNodeFactory , предоставленные с помощью LocalIndication . Это изменение вступит в силу при перекомпиляции использований этих модификаторов с использованием этой версии Compose. Бинарные/транзитивные зависимости не затронуты.

( I6bcdc , b/316914333 )
• Ввести флаг для управления поведением автоматической вложенной предварительной выборки: isAutomaticNestedPrefetchEnabled ( I8d448 )
• Ввести перегрузку для LazyGridState и rememberLazyGridState LazyGridState, которая принимает LazyLayoutCacheWindow . ( I51151 )
• Добавляет линейки для вставок окон. Добавляет DerivedRuler , позволяющий рассчитывать линейку на основе другой линейки. Изменяет PlacmentScope для реализации Density. ( I658bc , b/359260964 )
• Добавлена ​​функция-фабрика WindowInsets() с нулевым аргументом для простого создания пустых WindowInsets . ( I65f62 , b/395311689 )
• Добавлен PaddingValues.Zero для пустого PaddingValues . ( If193e , b/386255688 )

Исправления ошибок

• Перегрузка state BasicTextField будет сохранять курсор прокрученным в поле зрения при изменении его размера. ( I0eb41 , b/406187741 )

Version 1.8.0-beta01

29 января 2025 г.

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

API Changes

• SemanticsNodeInteraction.semanticsId() has been removed. Use SemanticsNodeInteraction.fetchSemanticsNode().id instead. ( Ie397a )
• Rewrite requestAutofill API to exist outside of autofill manager. ( Id1929 )
• 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 )

Исправления ошибок

• Fix text layout with ellipsis sometimes translating incorrectly during animations, see b/389707025 for more info ( Ie55b1 , b/389707025 )
• Fixed a bug in BasicText with TextAutoSize and maxLines set to 1. ( Ic0450 , b/376834366 )
• Text's minimum intrinsics height now takes minLines parameter into account. It means that minimum intrinsics height reported won't be smaller than the height required to satisfy the minLines parameter ( I225f9 , b/388299762 )

Version 1.8.0-alpha08

15 января 2025 г.

androidx.compose.foundation:foundation-*:1.8.0-alpha08 is released. Version 1.8.0-alpha08 contains these commits .

API Changes

• AutoSize: Renamed AutoSize to TextAutoSize and published APIs that enable creating custom TextAutoSize implementations. See TextAutoSizeSample for an example of a custom text auto size implementation. ( I85756 )
• Moved the DetectTapGesturesEnableNewDispatchingBehavior feature flag to ComposeFoundationFlags and renamed it to isDetectTapGesturesImmediateCoroutineDispatchEnabled . The old flag is deprecated and will now delegate to ComposeFoundationFlags.isDetectTapGesturesImmediateCoroutineDispatchEnabled instead. ( I62932 )

Исправления ошибок

• Enabled DetectTapGesturesEnableNewDispatchingBehavior by default. TapGestureDetector APIs now use the new dispatching behavior (immediate dispatch) by default. ( I9f2bc , b/369648479 )
• Fixed the requiredWidth/Height/Size modifiers to properly handle intrinsic sizes. ( Ie3d7d , b/368113212 )

External Contribution

• Commonized BasicTooltip in foundation and BasicTooltip/Tooltip in material3. ( Ifc2e6 )

Version 1.8.0-alpha07

11 декабря 2024 г.

androidx.compose.foundation:foundation-*:1.8.0-alpha07 is released. Version 1.8.0-alpha07 contains these commits .

API Changes

• Deleted ComposeFoundationFlags.RemoveBasicTextGraphicsLayerEnabled flag that helped revert the removal of internal graphicsLayer from BasicText . If you were using this flag please let us know of the reasons by filing a bug. Also you can just pass in Modifier.graphicsLayer() to your BasicText calls to achieve the same behavior as before. ( Id9f90 )
• Added default implementation for new stickyHeader DSL. ( I68986 )
• Has LocalAutofillHighlightColor composition local use a Color type. ( I0e05b )
• Renamed OverscrollEffect#withoutDrawing to OverscrollEffect#withoutVisualEffect . ( I1a154 )

Исправления ошибок

• Follow-up fix for an issue in AnchoredDraggable 's target calculation where it could settle at the wrong anchor for specific swipes. ( I23b87 , b/367660226 )

External Contribution

• 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 )
• We are ever slightly changing the way the cursor is drawn. You can use LocalCursorBlinkEnabled to disable the cursor drawing in tests. ( I4c697 )

Version 1.8.0-alpha06

13 ноября 2024 г.

androidx.compose.foundation:foundation-*:1.8.0-alpha06 is released. Version 1.8.0-alpha06 contains these commits .

API Changes

• Adds stylusHoverIcon modifier. ( Iff20a , b/331289114 )
• Deprecated AnchoredDraggableState 's confirmValueChange . Instead of vetoing state changes, disallowed anchors should not be in the active anchor set, and an OverscrollEffect should be used to indicate the unavailability of the requested action. ( Ia717f )
• Changes Autofill manager to be an interface. ( I84914 , b/376080755 )
• Adds OverscrollEffect#withoutDrawing and OverscrollEffect#withoutEventHandling APIs - these APIs create a wrapped instance of the provided overscroll effect that doesn't draw / handle events respectively, which allows for rendering overscroll in a separate component from the component that is dispatching events. For example, disabling drawing the overscroll inside a lazy list, and then drawing the overscroll separately on top / elsewhere. ( Idbb3d , b/266550551 , b/204650733 , b/255554340 , b/229537244 )
• Adding autofill support in text toolbar. ( Ie6a4c )
• Deprecates 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 )
• Changed the effectModifier property on OverscrollEffect to be node: DelegatableNode , consistent with other APIs. ( Ic0b46 , b/255554340 )
• Removed the experimental GlobalAssertions API. It's intended use was to run accessibility checks, see enableAccessibilityChecks() for that purpose instead. ( I59322 )

Version 1.8.0-alpha05

30 октября 2024 г.

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

Новые функции

• Support for auto-sizing text. Pass an AutoSize instance (eg AutoSize.StepBased ) to your favorite text composable (like BasicText ) and see your text size adapt to the available space! ( Ice7e0 , b/139320827 )
• Adds OverscrollFactory and LocalOverscrollFactory APIs to allow configuring overscroll within a hierarchy. The value provided through LocalOverscrollFactory will be used by default to create an OverscrollEffect . To create and remember an effect from the current provided factory, use rememberOverscrollEffect() . ( I51ca4 , b/255554340 )

API Changes

• Introduce CompositionLocal that can be used to modify the hue of Autofill's successful filling highlight. ( I32092 )
• Removed ScrollableDefaults.overscrollEffect - instead you should use rememberOverscrollEffect . This will create an instance of the current overscroll implementation provided with LocalOverscrollFactory . ( I1651a , b/255554340 ),( b/234451516 )
• 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 )
• Removes CombinedClickableNode . This experimental API was temporarily exposed to unblock performance work, but is no longer needed. Instead you should directly use Modifier.combinedClickable as with other modifier APIs. ( I4b658 )
• Adds overloads to horizontalScroll , verticalScroll , LazyColumn , LazyRow , LazyHorizontalGrid , LazyVerticalGrid , LazyHorizontalStaggeredGrid , LazyVerticalStaggeredGrid , HorizontalPager , and VerticalPager with support for specifying a custom OverscrollEffect . The provided OverscrollEffect will receive events, and be rendered within the bounds of these components. Note that drawing the same OverscrollEffect twice is unsupported - so you cannot draw the same OverscrollEffect provided to one of these components separately with Modifier.overscroll . The use case of drawing the overscroll outside of the bounds of these components will be addressed separately in the future. ( I2dc42 , b/266550551 , b/234274772 , b/224572538 , b/353805117 )

Version 1.8.0-alpha04

16 октября 2024 г.

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

API Changes

• Adds DelegatableNode#onDensityChange and DelegatableNode#onLayoutDirectionChange callbacks to allow updating node state when these change. ( I04f3e , b/340662451 )
• Paragraph and ParagraphIntrinsics now takes a list of all annotations applied to the AnnotatedString , previously it only had a list of SpanStyles . ( I12f80 )
• Introduced PointerInputModifierNode#touchBoundsExpansion , which can be used to enlarge the touch bounds of a single pointer input modifier. ( Iccf02 , b/335339283 )

Исправления ошибок

• Fixed a bug where positional thresholds passed to AnchoredDraggableDefaults.flingBehavior were not considered correctly in some scenarios. ( Ifdf0d , b/367660226 )
• 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 )
• Fixed a bug where OverscrollEffects passed to Modifier.anchoredDraggable would receive 2D deltas instead of 1D. ( Ie52c0 )

Version 1.8.0-alpha03

2 октября 2024 г.

androidx.compose.foundation:foundation-*:1.8.0-alpha03 is released. Version 1.8.0-alpha03 contains these commits .

API Changes

• Kotlin version update to 1.9 ( I1a14c )
• Introduced flag DraggableAddDownEventFixEnabled ( I848d5 )
• Introduced a new Semantics Role called Carousel to emulate the list behavior in Pagers for a11y services. ( Id354b , b/354109776 , b/239672673 )
• Removed the implicit graphicsLayer modifier from BasicText composable. Added experimental ComposeFoundationFlags.RemoveBasicTextGraphicsLayerEnabled flag to be able to revert to the old behavior. ( Ie478d )
• Added Modifier.recalculateWindowInsets() to allow children in the hierarchy to use insetsPadding even when parents aligned them without consumeWindowInsets() . ( I7f9e4 )

Исправления ошибок

• Implement gesture pick-up in detectDragGestures , draggables and scrollables. Now if a child draggable gives up on a gesture, the parent has the opportunity to pick it up. This allows for a more continuous and integrated gesture handling. ( Ic88fe )
• Update fling cancellation behavior in scrollables. Now if a scrollable flings and hits the bounds it will correctly pass on the fling velocity to the next scrollable in the chain instead of continue to drive the fling. ( I9326a )

Версия 1.7.0

4 сентября 2024 г.

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

Important changes since 1.6.0

• Performance of Modifier.clickable , Modifier.focusable , Modifier.indication , Modifier.scrollable and Modifier.draggable has been significantly improved. As a part of this effort, the following API changes were made in addition to internal changes
  • Added a new Indication API, IndicationNodeFactory . This leads to more performant Indication implementations compared to the previous (now deprecated) rememberUpdatedInstance API. For migration information, see developer.android.com .
  • clickable / combinedClickable / selectable / toggleable now accepts a nullable MutableInteractionSource parameter. If null, and the provided Indication is an IndicationNodeFactory , the Indication can be lazily created only when needed, which improves performance. If you are not hoisting and using the MutableInteractionSource , it is recommended to pass null instead of passing remember { MutableInteractionSource() } .
  • Indication#rememberUpdatedInstance has been deprecated. It has a high unavoidable performance penalty, and prevents other optimizations. Instead, you should use the new IndicationNodeFactory API.
• BasicTextField using a TextFieldState is now stable and we advise all call-sites to begin migration from BasicTextField(value, onValueChange) to BasicTextField(TextFieldState) .
• The ClickableText has been deprecated. To add clickable links to your text, use BasicText with the new LinkAnnotation annotation in your AnnotatedString . LinkAnnotation allows for custom styling based on link state (eg focused, hovered).
• 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 )
• Item appearance and disappearance animation support was added into LazyColumn and LazyRow . Previously it was possible to add Modifier.animateItemPlacement() modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called Modifier.animateItem() which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. ( I2d7f7 , b/150812265 )
• Implemented experimental support for long screenshots in Compose scroll containers using the official Android API ( ScrollCaptureCallback ).
• 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 ).
• LazyLayout prefetch requests can be marked as urgent now, meaning that we expect this item to be needed in the next frame and want to ignore frame budget to make sure to do more work in advance ( Id513f )
• Support stylus handwriting feature on devices after Android U. ( I002e4 )
• Various APIs have been promoted to stable
  • Pagers, snapping, window insets

API Changes

• Adds an experimental API for configuring prefetch behavior of LazyGrids similar to the existing experimental API for LazyLists . This includes support for prefetching items in nested LazyGrids . Similiar to LazyListPrefetchStrategy , the implementation default is to prefetch the first 2 nested items of each grid, but this can be configured by the new LazyGridPrefetchStrategy(nestedPrefetchItemCount) and LazyListPrefetchStrategy#onNestedPrefetch APIs. ( I591c4 )
• Renamed SemanticsProperties.Editable to IsEditable and changes SemanticsPropertyReceiver.editable to a val isEditable . The property is now a boolean and always specified by text fields. ( I8acd8 )
• Moved basicMarquee default values into MarqueeDefaults object. ( I12ff6 )
• Renamed basicMarquee delayMillis parameter to repeatDelayMillis . ( I12ff6 )
• Update API for styling the links: moved the TextLinkStyles to the TextStyle and removed the TextDefaults from material ( I5477b )

Исправления ошибок

• Renamed LayoutCoordinates.introducesFrameOfReference to LayoutCoordinates.introducesMotionFrameOfReference to better reflect its purpose. Renamed related function to calculate coordinates based on that flag. ( I3a330 )
• Removed 'Default' from the MarqueeDefaults properties. ( I1d8a0 )
• Removed 'Marquee' from MarqueeDefaults properties. ( Iad4f4 )
• Removed TextLinkStyles from the TextStyle class. Instead, TextLinkStyles is part of the LinkAnntation constructor and the AnnotatedString.fromHtml method ( I90b2b )
• Fixed a bug where Pager would snap when flinging towards a bound while already settled at the bound. ( I9f373 , b/339171222 )

Version 1.7.0-beta01

14 мая 2024 г.

androidx.compose.foundation:foundation-*:1.7.0-beta01 is released. Version 1.7.0-beta01 contains these commits .

API Changes

• Added KeyboardOptions.shouldShowKeyboardOnFocus property back as deprecated hidden for binary compatibility. ( I15cfe )
• Modifier.anchoredDraggable now reverses drag deltas by default for components with a Horizontal orientation when used in an RTL layout. ( I3c6d9 )
• AnnotatedString.hasEqualsAnnotations is now hasEqualAnnotations . ( I685c0 )
• Updated the API for getting Material themed links in text. Specifically, removed the methods from the TextDefaults for constructing themed LinkAnnotations and parse HTML with themed links. Instead, added a TextLinkStyles class that allows to style the links as a parameter to the Text composable. ( I31b93 )
• Replaced onDragStarted and onDragStopped with non-suspend callbacks. ( I59de8 )

Исправления ошибок

• Fixed a bug where Pager would crash when the contentPadding was bigger than the incoming constraints. Pager now coerces negative values returned from PageSize to 0. ( Iba5d8 , b/314008560 )

Version 1.7.0-alpha08

1 мая 2024 г.

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

Новые функции

• Added right-click context menu to BasicTextField and SelectionContainer with items for cut, copy, paste, and select-all actions. ( If8c93 , Ia2b49 , I6f268 )

API Changes

• LazyLayout prefetch requests can be marked as urgent now, meaning that we expect this item to be needed in the next frame and want to ignore frame budget to make sure to do more work in advance ( Id513f )
• 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 )
• Renamed onClicked to onClick inside LinkInteractionListener ( Iaa35c )
• Change action lambda for getScrollViewportLength as per API council feedback. ( Ibc74a )
• Renamed stylus handwriting delegation APIs. ( Ica45f , b/327271923 )
• Rename TextInclusionStrategy.isInside to isIncluded . Make Paragraph/MultiParagraph#getRangeForRect() return type non nullable. ( I51f26 )

Исправления ошибок

• Added "Select all" to all text contextual menus in SelectionContainer . ( Ib750e , b/240143283 )
• Fixed long screenshot capture for scrolling containers with reverseScrolling=true . ( I7c59c )
• Fixed an issue where AnchoredDraggableState 's currentValue would change when approaching the state's bounds. ( Iea30b , b/333846848 )

External Contribution

• Renamed PrefetchExecutor -> PrefetchScheduler to better reflect its responsibilities. ( Ib9154 )
• 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.foundation:foundation-*:1.7.0-alpha07 is released. Version 1.7.0-alpha07 contains these commits .

Новые функции

• Added a TextDefaults object that contains methods to construct a LinkAnnotation and parse HTML-tagged string which apply MaterialTheme to the links. ( I98532 , b/139312671 )
• Item appearance and disappearance animation support was added into LazyVerticalGrid and LazyHorizontalGrid . Previously it was possible to add Modifier.animateItemPlacement() modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called Modifier.animateItem() which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. ( Ib7d12 , b/330510929 )
• Item appearance and disappearance animation support was added into LazyVerticalStaggeredGrid and LazyHorizontalStaggeredGrid . Previously it was possible to add Modifier.animateItemPlacement() modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called Modifier.animateItem() which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. ( I69bc9 , b/330511290 )

API Changes

• Adds ContextMenuColors and the associated LocalContextMenuTheme ProvidableCompositionLocal . The colors of the context menu on text fields and selectable text can be modified by providing the composition local. ( Ifa154 )
• Text links got pressed state styling option in addition to normal styling, hovered and focused. ( I5f864 , b/139312671 )
• Introduce ViewConfiguration.HandwritingGestureLineMargin for handwriting gestures. Support handwriting gesture for BasicTextField . ( Ie6e13 , b/325660505 )
• Removed DelegatableNode.scrollIntoView for the 1.7 release since we didn't have time to finish stabilizing the rest of the related API surface. This function will be re-introduced in 1.8 ( I6cf61 , b/333421581 , b/332900232 )
• 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 )
• Introduce requestScrollToItem for LazyStaggeredGrid . For each measure-pass, the client may now opt-out of maintaining index based on the key by calling requestScrollToItem . This does not change existing behavior in any way unless requestScrollToItem is called. ( I63983 )
• Introduce requestScrollToPage in Pager. For each measure-pass, the client may now opt-out of maintaining index based on the key by calling requestScrollToPage . This does not change existing behavior in any way unless requestScrollToPage is called. ( Ic4213 )
• Introduced requestScrollToItem for LazyGrids . For each measure-pass, the client may now opt-out of maintaining index based on the key by calling requestScrollToItem . This does not change existing behavior in any way unless requestScrollToItem is called. ( I0a7a0 )
• 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 )
• 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 )
• 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 )
• 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 )
• Stabilized majority of the remaining experimental APIs that were introduced with the new BasicTextField . ( I714e2 )
• Added textObfuscationCharacter parameter to BasicSecureTextField that controls which character to use while obfuscating the contents. ( I0588b )
• 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 )
• Introduce LocalBringIntoViewSpec , a platform dependent focus scrolling behavior that is applied at the Scrollable modifier layer. ( I27aa5 , b/317453911 )
• Removed TextFieldCharSequence . TextFieldBuffer.originalValues is replaced with TextFieldBuffer.originalText and TextFieldBuffer.originalSelection . ( I2c7d6 )
• ImeOptions.hintLocales is no longer nullable. If you want to pass an empty Locale list, please use LocaleList.Empty . ( Ic5bc4 )
• Renamed getOffsetFractionForPage to getOffsetDistanceInPages . ( Ia05e2 )

Исправления ошибок

• When InputTransformations are joined with next , their KeyboardOptions are now properly merged by individual options using the new KeyboardOptions.merge method. ( Ie5304 , b/295951492 )
• AnchoredDraggableState 's targetValue now does not consider positional thresholds anymore. It now has an implicit threshold of 50%, meaning that the targetValue changes at the midpoint between two anchors. ( I82c2c )

External Contribution

• Renamed 2 scroll APIs ( I56a75 )

Version 1.7.0-alpha06

Новые функции

• Item appearance and disappearance animation support was added into LazyColumn and LazyRow . Previously it was possible to add Modifier.animateItemPlacement() modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called Modifier.animateItem() which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. ( I2d7f7 , b/150812265 )
• Clients of LazyColumn/LazyRow may now opt-out of maintaining an index based on the key for the upcoming measure-pass by calling a non-suspend LazyListState.requestToScroll . ( I98036 , b/209652366 )
• 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 )
• 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. This flag will be removed before 1.7 beta. ( I2b055 , b/329296471 )
• Introduce new GraphicsLayer API to provide more flexibility in placement and rendering of GraphicsLayer instances and support intrinsic rendering features without needing to coordinate with Composable implementations to specify GraphicsLayer modifier instances.

API Changes

• 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 )
• Renamed outOfBoundsPageCount to beyondViewportPageCount . ( I129c6 )
• fun ClipEntry.getMetadata() is changed to val ClipEntry.clipMetadata . ( I50155 )
• Removed TextFieldState.valueAsFlow() . Prefer using snapshotFlow { state.text } , or snapshotFlow { TextFieldCharSequence(state.text, state.selection) } ( I7d629 )
• Reorganized InputTransformation.transformInput parameters. Removed originalValue: TextFieldCharSequence . Instead TextFieldBuffer now carries this value with the same name. Also removed the valueWithChanges: TextFieldBuffer parameter. TextFieldBuffer now is the receiver scope on the function. ( I919cc )
• BasicTextField(state) variant and BasicSecureTextField now use KeyboardActionHandler instead of KeyboardActions to process actions taken by the software keyboard. ( I58dda )
• Stylus handwriting delegation APIs to support stylus handwriting on "fake" text input fields. ( I9c09c , b/327271923 )
• Renamed KeyboardOptions.shouldShowKeyboardOnFocus to showKeyboardOnFocus . ( Ib4b7a , b/295951492 )
• Removed hintMediaTypes parameter from Modifier.contentReceiver . Developers were already encouraged to check the received TransferableContent 's media type since it could be incompatible with the configured hintMediaTypes . ( I82f99 )
• Reordered the parameters of BasicSecureTextField . Removed keyboardType and imeAction parameters in favor of full KeyboardOptions class while keeping the same defaults appropriate for BasicSecureTextField . Also removed the scrollState parameter. ( Ibbfa9 )
• TextFieldState.text 's type is changed from TextFieldCharSequence to just CharSequence . Therefore, added TextFieldState.selection: TextRange and TextFieldState.composition: TextRange? to read the current selection and composition values directly from the state object.
• Removed TextFieldState.forEachTextValue . ( Idb2a2 )
• 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 )
• ClipboardManager.setClip now accepts null to be able to clear the Clipboard. ( I7d2e9 )
• ReceiveContentListener is converted to a function interface. Also Modifier.receiveContent overload that takes in a lambda is removed since ReceiveContentListener is a function interface now.
• Modifier.receiveContent is renamed to Modifier.contentReceiver . ( I1e6af )
• Renamed TransferableContent.consumeEach to TransferableContent.consume . ( I1e462 )
• rememberTextFieldState has graduated to a Stable API. ( I37999 )

Исправления ошибок

• Removed experimental override of BasicText with onLinkClicked argument. A replacement API for hyperlinks support will follow in the future. ( I107d5 )
• Removed Codepoints related methods and properties under TextFieldState and TextFieldBuffer . Also removed the inChars suffixes from the remaining selection and composition related APIs. ( Ief7ce )
• AnchoredDraggable 's currentValue will now update when passing through an anchor point. Use settledValue to receive the previous currentValue semantics, only updating when settling at an anchor. The progress is now exposed as a function (requiring a starting and end point) instead of a property. ( Ibe6e8 , b/318707189 , b/298271489 , b/294991954 )
• BasicTextField(state) , TextFieldState , InputTransformation , OutputTransformation , TextFieldLineLimits , TextFieldDecorator are graduated to stable. ( I9582b )
• Introduced InterceptPlatformTextInput for helping write low-level IME-related tests and other low-level IME use cases. PlatformTextInputTestOverride has been deprecated. ( I862ed , b/322680547 )
• Split restrictedConstraints() to two methods: fitPrioritizingWidth() and fitPrioritizingHeight() ( I6d7fd )

External Contribution

• Added 2 new API isLastScrollForward / isLastScrollBackward to check scroll direction for latest scroll action, return false if no scroll action yet. ( I63a0e )

Version 1.7.0-alpha04

6 марта 2024 г.

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

API Changes

• Support stylus handwriting feature on devices after Android U. ( I002e4 )
• Added hintLocales to KeyboardOptions to provide TextFields with the ability to hint IMEs with specific locales to preset a preferred language. ( Id18c2 )
• Removed the Experimental BasicTextField2 and BasicSecureTextField overloads that took value: String and onValueChange: () -> String parameters. ( I568b4 )
• Add an optional applySemantics function to InputTransformation to influence the semantics of the BasicTextField2 that it's applied to. ( I74a2f , b/170648072 )
• 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 )
• BasicTextField2 is renamed to BasicTextField . ( Ie5713 )
• FocusRequester.createRefs is now stable ( I4d92c , b/261436820 )
• Introduced DelegatableNode.scrollIntoView() to allow modifier nodes to make scrollIntoView requests directly. ( I2b3b7 , b/299939840 )
• Introduced DelegatableNode.requireView() to allow modifier nodes to get the current Android View without reading a composition local. ( I40768 )
• Introducing contextual layout information within Contextual Flow Row Scope and Contextual Flow Column Scope, featuring line index, position, and constraints on maximum width and height to stay in specified position. Items exceeding maximum width/height may flow to the next line or be omitted based on overflow settings. ( Id13f8 , b/292114798 )

Исправления ошибок

• Fixed a bug where in certain conditions toggling enabled or readOnly attributes of TextField would cause a crash. ( Iae17b )

Version 1.7.0-alpha03

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

API Changes

• 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 )
• Performance optimizations in DraggableAnchors used by AnchoredDraggable . ( I89cff )
• BasicTextField2 and related APIs under androidx.compose.foundation.text2 package are moved to androidx.compose.foundation.text . ( I9f635 )
• BasicTextField2 no longer accepts a CodepointTransformation parameter. Use BasicSecureTextField or OutputTransformation . ( Id34ff )
• Added method to compare only the annotations of two AnnotatedStrings . ( I32659 )
• 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 )

Исправления ошибок

• Cursor animation no longer requests frames between on and off states. ( Ia2253 )
• KeyboardOptions ' deprecated copy constructors will now correctly copy all properties. ( If12de )

Version 1.7.0-alpha02

7 февраля 2024 г.

androidx.compose.foundation:foundation-*:1.7.0-alpha02 is released. Version 1.7.0-alpha02 contains these commits.

API Changes

• HorizontalPager , VerticalPager and PagerState are promoted to stable. ( I67660 , b/316966909 )
• Added LocalTextLinkStyle composition local that allows to change the style of the links in Text across the app. If you're using your own theme in the app, you should be setting this composition local according to your theming. When using Material theme the color of the link by default will be set to Material's primary color. ( I7eb10 )
• Introduced receiveContent modifier that provides developers with a way to receive rich content in Jetpack Compose.
• receiveContent integrates with BasicTextField2 to accept rich content provided by the software keyboard, or via Clipboard paste action. ( I81b72 )
• In this change we're replacing SnapFlingBehavior with TargetedFlingBehavior in pager to unlock other use cases and provide greater flexibility. ( I762ea )
• In this change we're making Snapping APIs Stable. We're also cleaning up some of the testing code and adding more samples to Snapping. ( Id8da9 )
• Introduce TargetedFlingBehavior , a FlingBehavior that allows propagating information about the state of the ongoing animation and it's target scroll offset. ( I6a207 )

Исправления ошибок

• BasicTextField2 now keeps the cursor in view while typing when it has been scrolled out of view or would move out of view due to input. ( Ieb856 , b/237190748 )

External Contribution

• Adds an experimental API for configuring prefetch behavior of LazyLists. ( I022a4 )

Version 1.7.0-alpha01

24 января 2024 г.

androidx.compose.foundation:foundation-*:1.7.0-alpha01 is released. Version 1.7.0-alpha01 contains these commits.

Новые функции

• Added a new Indication API , IndicationNodeFactory . This leads to more performant Indication implementations compared to the previous (now deprecated) rememberUpdatedInstance API. For migration information, see developer.android.com .
• clickable / combinedClickable / selectable / toggleable now accepts a nullable MutableInteractionSource parameter. If null, and the provided Indication is an IndicationNodeFactory , the Indication can be lazily created only when needed, which improves performance. If you are not hoisting and using the MutableInteractionSource , it is recommended to pass null.

API Changes

• Introduce DecayAnimation in AnchoredDraggable , this change adds a decayAnimationSpec parameter to AnchoredDraggable allowing to use decay animation when settling to one of the anchors. The change also includes renaming the existing animationSpec to snapAnimationSpec to help understanding the use case of each spec.
• BasicTextField2 is available for experimental use. It should be roughly at feature parity with BasicTextField , and behavior should be production-ready. However, the API remains experimental for now. Before stabilizing, it will be renamed to BasicTextField and moved into the same package.
• Introduced the first draft of the OutputTransformation API for BasicTextField2 . This API replaces most of the use cases of VisualTransformation in the old BasicTextField . However it is not complete yet, and some things won't work correctly, but we'd appreciate any feedback on the API usability for your use cases. ( aosp/2708848 )
• Introduced LinkAnnotation that allows to add links and clickables into text. Links feature is not complete yet and more API changes are coming.
• Introduced receiveContent modifier that provides developers with a way to receive rich content in Jetpack Compose.
• receiveContent integrates with BasicTextField2 to accept rich content provided by the software keyboard, or via paste from Clipboard.
• KeyboardOptions.shouldShowKeyboardOnFocus allows you to disable the default behavior of BasicTextField of requesting a software keyboard on focus.
• TextInputService and LocalTextInputService are now deprecated. Use PlatformTextInputModifierNode to integrate directly with platform IME APIs instead. ( aosp/2862698 )
• Indication#rememberUpdatedInstance has been deprecated. It has a high unavoidable performance penalty, and prevents other optimizations. Instead, you should use the new IndicationNodeFactory API.

Исправления ошибок

• BasicTextField will now pre-validate a small selection of offset mappings when VisualTransformation is passed. This helps catch common coding errors that lead to unrecoverable exceptions in later measure or draw passes. By throwing during composition, it is more likely developers will see these errors during development helping avoid production crashes. ( I0fd42 )
• VisualTransformation will not throw if you return an invalid index for an invalid index ( b/316401857 )

API Changes

• 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 )

• Exposing startDragImmediately in AnchoredDraggable gives control for detecting dragging gestures when using it. It is useful to set it when the widget is animating to a target anchor. See Sample . ( Ie6d13 , b/285139987 )

• Foundation Tooltip APIs are now @ExperimentalFoundationApi ( I30b0b )

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

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

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

  The DragAndDropEventType has been removed ( I645b1 )

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

• clippingEnabled parameter of Modifier.magnifier is renamed to clip .

• magnifierCenter parameter of Modifier.magnifier is made nullable preserving the same default behavior. ( I6aa66 )

• 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 )

Исправления ошибок

• FocusRequesterModifier is deprecated in favor of FocusRequesterNode ( I7f4d7 , b/247708726 , b/255352203 , b/253043481 , b/247716483 , b/254529934 , b/251840112 , b/251859987 , b/257141589 )
• AndroidFont constructor with variationSettings is now a stable API, and can be used to create new types of font descriptors. ( I5adcc , b/261565807 )
• Introduced PinnableContainer api propagated by lazy lists via a composition local which allows to pin current item. This means such item will not be disposed when it is scrolled away from the view. For example, Modifier.focusable() will pin the current focused item via this mechanism. ( Ib8881 , b/259274257 , b/195049010 )
• Rewrote the way scrollables respond to bringIntoViewRequesters and focusables to better model the complexity of those operations and handle more edge cases. ( I2e5fe , b/241591211 , b/192043120 , b/237190748 , b/230756508 , b/239451114 )
• More return type nullability of deprecated-hidden functions ( Ibf7b0 )
• Added experimental TextMotion to TextStyle to define Text either to be Static(default) or Animated. Use TextMotion.Animated if Text is going to be scaled, translated, or rotated via animation. ( I24dd7 )
• Add TextFieldFocusModifier to fix focus navigation behaviour for android platform ( I00303 )
• 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 )

Исправления ошибок

• Adjustments in the snapping physics in SnapFlingBehaviour for a more natural feel.

Известная проблема

• When updating from androidx.compose.foundation:1.4.0-alpha03 to androidx.compose.foundation:1.4.0-alpha04 , you might experience a java.lang.NoSuchFieldError error. Here is where the issue was orginially reported. A fix has been submitted, and will be available on the next Compose update. As a work around, update your androidx.compose.material and androidx.compose.material3 libraries to the latest version(1.1.0-alpha04) or downgrade your androidx.compose.foundation to 1.4.0-alpha03.

Version 1.4.0-alpha03

7 декабря 2022 г.

androidx.compose.foundation:foundation:1.4.0-alpha03 and androidx.compose.foundation:foundation-layout:1.4.0-alpha03 are released. Version 1.4.0-alpha03 contains these commits.

API Changes

• 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 )
• Introduce Page accessibility actions: PageUp , PageDown , PageLeft , PageRight . Note that these are only available from API 29. ( Ida4ab )
• Introduce HorizontalPager and VerticalPager , a way of showing composables in a Pager manner. Introduced PagerState to control the Pagers as well as query information about the Pager's current state. Introduced PageSize , a way of controlling the size of a Pager's page, this can be used to create a carousel like Pagers. Introduced PagerSnapDistance , a way to control how snapping will work in Pager's fling behavior. ( I01120 )
• Introduced an overload in SnapFlingBehavior.performFling to help to understand where the fling will settle. ( I569f6 )
• Removed OverscrollEffect#isEnabled . Instead of needing to remember and set this flag, just don't dispatch events to the overscroll effect in cases where you do not want overscroll to show (for example if ScrollableState#canScrollForward/backward both return false). ( I1a4b0 , b/255554340 , b/255557085 )
• Added ScrollableState#canScrollForward and ScrollableState#canScrollBackward to query whether a ScrollableState has room to scroll in either direction (whether it is at the minimum / maximum of its range). This defaults to true for backwards compatibility with existing implementations of ScrollableState . Consumers can use this to show indication to the user that there is still room to scroll, and this could also be used to avoid dispatching delta to ScrollableStates that have no room to scroll in a given direction, to reduce unnecessary work. ( Idf1a0 , b/255557085 )
• 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.
• Update snapStepSize naming to be consistent with other methods in SnapLayoutInfoProvider . ( Ife67c )
• Added EmojiCompat to Compose ( Ibf6f9 , b/139326806 )
• Renamed consumedWindowInsets() to consumeWindowInsets() and withConsumedWindowInsets() to onConsumedWindowInsetsChanged() and made the Modifiers public. ( Ie44e1 )

Исправления ошибок

• The crash with Modifier.animateItemPlacement() and Lazy grids was fixed. It was happening in some conditions when the new items count is smaller then the previous one. ( I0bcac , b/253195989 )

API Changes

• 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 )
• Added WindowInsets.imeAnimationSourc e and WindowInsets.imeAnimationTarget to determine the animation progress and know where the IME will be after animation completes. ( I356f1 , b/217770337 )

Новые функции

• This is the first beta release of 1.2!

API Changes

• Added experimental BeyondBoundsInterval that can be used by custom implementations of LazyList when they layout items beyond visible bounds ( Ifabfb , b/184670295 )
• 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 default values for the optional members of LazyLayoutItemProvider interface. ( Iba8a0 )
• In the LazyLayoutItemProvider api instead of a factory returning the composable lambda by index we now have a simpler composable function Item accepting the index. ( Id2196 )
• LazyLayoutItemsProvider is renamed to LazyLayoutItemProvider ( I0638c )
• LazyLayoutItemsProvider.itemsCount is renamed to itemCount ( Id409c )
• 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 )

• Added experimental imeNestedScroll() modifier so that developers can control the IME through scrolling. ( I60759 )

Исправления ошибок

• Fixed regression where text fields would not hide the keyboard when removed from the composition while focused. ( I7a410 , b/230536793 , b/225541817 )
• Support ellipsis when height is limited and doesn't fit all text lines ( Ie528c , b/168720622 )
• BringIntoViewRequester.bringIntoView will now always suspend until the request is either completed or was interrupted by a newer, non-overlapping request. Overlapping requests will be queued. ( I43e7f , b/216790855 )
• Concurrent BringIntoViewRequester.bringIntoView calls for rectangles that are completely overlapping will now only honor the larger rectangle's request. ( I34be7 , b/216790855 , b/184760918 )
• 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 )
• Modifier.bringIntoViewRequester no longer uses onGloballyPositioned . ( I630f5 )

External Contribution

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

Version 1.2.0-alpha08

androidx.compose.foundation:foundation:1.2.0-alpha08 and androidx.compose.foundation:foundation-layout:1.2.0-alpha08 are released. Version 1.2.0-alpha08 contains these commits.

API Changes

• 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 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 )
• 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 )
• New experimental LazyLayout API is introduced. This allows you to build your own components like LazyColumn of LazyVerticalGrid . Note that the API is in its early stages and can be changed in the future releases. ( Iba2bc , b/166591700 )
• AndroidFont now takes typefaceLoader as a constructor parameter. ( I2c971 )
• WindowInsets companion now exposes the visibility (whether they are on the screen, regardless of whether they intersect with the window) and the size they could be if they are available on the device, but not currently active. ( I65182 , b/217770337 )

Version 1.2.0-alpha07

6 апреля 2022 г.

API Changes

• Added a PinnableParent API that allows children of lazy layouts to prevent the currently composed items from being disposed ( Ibbdd0 , b/184670295 )
• LazyListLayoutInfo and LazyGridLayoutInfo now have beforeContentPadding and afterContentPadding fields ( I3b628 , b/200920410 )
• Added KeyboardType.Decimal as an alternative to Keyboard.Number for specifically including decimal separator in IME. ( Iec4c8 , b/209835363 )
• Add new font descriptor Font(DeviceFontFamilyName) to optionally lookup system-installed fonts during font fallback chains. ( I30468 , b/219754572 )
• PointerEventType.Scroll and PointerEvent.scrollDelta are stable APIs now ( I574c5 , b/225669674 )
• 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 )
• Updated FontFamily.Resolver to integrate System-wide bold text accessibility setting ( I6c1e7 )
• 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 )

Version 1.2.0-alpha06

API Changes

• Added RequestFocus semantics action to request focus on the focusable target. ( I17b71 )
• 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 )
• WindowInsets.asPaddingValues(Density) was added to allow developers to do the conversion without needing to be in composition. ( I94c35 )
• 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 )

Исправления ошибок

• Scroll modifiers ( Modifier.verticalScroll() , Modifier.horizontalScroll() , and Modifier.scrollable() ) will now scroll to keep the focused composable visible if the scroll area is resized and the focused composable was previously visible.
• TextFields will now be kept above the keyboard when they are focused and the keyboard is shown, when inside a non-lazy scrollable and the soft input mode is ADJUST_RESIZE . ( I4a485 , b/190539358 , b/192043120 , b/216842427 )

Version 1.2.0-alpha04

23 февраля 2022 г.

androidx.compose.foundation:foundation:1.2.0-alpha04 and androidx.compose.foundation:foundation-layout:1.2.0-alpha04 are released. Version 1.2.0-alpha04 contains these commits.

API Changes

• BringIntoViewResponders are no longer required to manually pass requests up to parent responders, and are instead required to immediately return the rectangle they want their parent to bring into view. ( I8e66a )
• Support async font loading in Text ( I77057 , b/214587005 )
• LazyVerticalGrid now supports line breaking before items with span not fitting inside the current line. ( I05c40 , b/207462103 )
• Renamed excludeFromSystemGestures to systemGesturesExclusion ( I19526 )
• LazyVerticalGrid now supports reverseLayout. ( I6d7d7 , b/215572963 , b/211753558 )
• Add WindowInsets.only() method to allow developers to include only dimensions from the WindowInsets. ( I14c94 , b/217768486 )

• 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 CompoableTarget 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 )

Исправления ошибок

• Now it is allowed to pass negative scroll offsets into LazyGridState.scrollToItem() and LazyGridState.animateScrollToItem() . ( I025c6 , b/211753558 )

Version 1.2.0-alpha03

9 февраля 2022 г.

androidx.compose.foundation:foundation:1.2.0-alpha03 and androidx.compose.foundation:foundation-layout:1.2.0-alpha03 are released. Version 1.2.0-alpha03 contains these commits.

API Changes

• notifyFocusedRect methods in TextInputSession and TextInputService are now deprecated and won't be called. Use BringIntoViewRequester instead. ( Ia4302 , b/192043120 , b/216842427 , b/178211874 )
• Animations were enabled for items of lazy grids with Modifier.animateItemPlacement(). ( Ib6621 , b/211753218 )
• BringIntoViewRequester now propagates requests to the hosting Android View. ( Ia7a51 )
• 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 )
• 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 )
• You can now specify the content type for the items of LazyVerticalGrid - item/items functions on LazyGridScope now accept such parameter. Providing such information helps item composition reusing logic to make it more efficiently and only reuse the content between the items of similar type. ( I7b355 , b/215372836 )
• LazyListLayoutInfo and LazyGridLayoutInfo now have new properties: viewportSize , orientation , reverseLayout ( Ifc8ed , b/200920410 )
• You can now specify the content type for the items of LazyColumn/LazyRow - item/items functions on LazyListScope now accept such parameter. Providing such information helps item composition reusing logic to make it more efficiently and only reuse the content between the items of similar type. ( I26506 )
• 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 )
• Adds Modifiers for WindowInsets, both for padding and sizing. This allows some content to extend into the inset area, and still have primary content stay out of the inset area. For example, windowInsetsPadding can be used to pad the content area to avoid areas that may be fully or partially covered. ( Id0395 , b/213942085 )

Исправления ошибок

• 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 )
• Text fields no longer require an extra back press when the cursor handle is showing. ( Ideb4b , b/205726883 )

API Changes

• Added NonRestartableComposable to methods that are overloads of existing methods without complex logic. This reduces compiler generated memoization checks (equals) for all parameters which are repeated in the inner function that is called. ( I90490 )
• Added excludeFromSystemGesture Modifiers for easy access to Android's setSystemGestureExclusionRects ( I46f07 )

Исправления ошибок

• Text selection magnifier behavior has been polished to match the platform magnifier. ( Idd918 , b/206833278 )

Scrolling programmatically via the methods on the state will still be allowed. ( I7eae9 , b/201150093 )
• Add onSizeChanged callback to magnifier modifier. ( I6879f )
• The magnifier widget now shows when dragging selection handles in a SelectionContainer . ( I30b38 , b/139320979 )

Версия 1.1.0

9 февраля 2022 г.

androidx.compose.foundation:foundation:1.1.0 and androidx.compose.foundation:foundation-layout:1.1.0 are 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

API Changes

• Support for horizontal spans was added to LazyVerticalGrid. ( I7e2fa , b/176758183 )

• Experimental ability to animate Lazy lists item positions was added. There is a new modifier available within LazyItemScope called Modifier.animateItemPlacement() . Usage example:

    var list by remember { mutableStateOf(listOf("A", "B", "C")) }
    LazyColumn {
        item {
            Button(onClick = { list = list.shuffled() }) {
                Text("Shuffle")
            }
        }
        items(list, key = { it }) {
            Text("Item $it", Modifier.animateItemPlacement())
        }
    }
  

  • When you provide a key via LazyListScope.item or LazyListScope.items this modifier will enable item reordering animations. Aside from item reordering all other position changes caused by events like arrangement or alignment changes will also be animated. ( I59e7b , b/150812265 )

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.foundation:foundation:1.0.0-beta08 and androidx.compose.foundation:foundation-layout:1.0.0-beta08 are released. Version 1.0.0-beta08 contains these commits.

API Changes

• NestedScrollSource enum is replaced by an inline class. ( Ie321b , b/187055290 )
• Refactored enum usages to inline classes to avoid issues with exhaustive when statements when new enum values are added. ( I2b5eb )
• Adds a tap timeout to clickable / toggleable to prevent showing a ripple during a scroll / drag ( Ia2704 , b/168524931 )
• 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 )
• 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 )
• AnnotatedString.withAnnotation functions are now ExperimentalTextApi instead of ExperimentalComposeApi. ( I0cd0a )
  • TextUnit constructor with TextUnitType is now ExperimentalTextApi instead of ExperimentalComposeApi.
• PaddingValues is now @Stable rather than @Immutable ( I88c50 )

Исправления ошибок

• Fix crashes of long press the blank area in non-empty text. ( I33ab5 , b/187437299 )
• Show Toolbar after SelectAll ( I495d9 , b/185919613 )
• Fix for scrollable containers clipping its children on the cross axis. It was easily reproducible if you have a LazyRow with Card items. now the shadow will not be clipped. ( Icb635 , b/186318448 )
• Fixed an issue where ripples / other indication would sometimes get stuck on a long click when using Modifier.combinedClickable ( I2298c , b/186223077 )
• 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 )
• 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

• Added Clip Selection Handle ( Iff80d , b/183408447 )

Исправления ошибок

• LazyColumn/Row will now keep up to 2 previously visible items active (not disposed) even when they are scrolled out already. This allows the component to reuse the active subcompositions when we will need to compose a new item which improves the scrolling performance. ( Ie5555 )
• Remove paintBackground. ( I38660 )
• Draw Selection Background using DrawScope. ( I73c61 , b/186674472 )

Version 1.0.0-beta05

21 апреля 2021 г.

androidx.compose.foundation:foundation:1.0.0-beta05 and androidx.compose.foundation:foundation-layout:1.0.0-beta05 are released. Version 1.0.0-beta05 contains these commits.

API Changes

• FlingBehavior interface is now marked as @Stable. All implementations should comply with the @Stable contract. ( I93354 , b/184830577 )

Исправления ошибок

• Fixed ACTION_SCROLL_FORWARD , ACTION_SCROLL_BACKWARD , accessibilityActionScrollLeft , accessibilityActionScrollUp , accessibilityActionScrollRight and accessibilityActionScrollDown accessibility scroll actions. Instead of scrolling to the end of the scrollable, it will now scroll by one screen in the given direction. ( Ieccb0 )
• The AndroidManifest files from ui-test-manifest and ui-tooling-data are now compatible with Android 12 ( I6f9de , b/184718994 )

  • Provide the full CompositionLocal interface for LocalSoftwareKeyboardController, allowing it to be set (especially useful in tests) ( I579a6 )
• TextOverflow.Visible is introduced. ( Ic8f89 )
• Public instances of RowScope , ColumnScope , BoxScope , BoxWithConstraintsScope were removed. ( I4e83e , b/181869067 )

Исправления ошибок

• Fixed the issue when items of LazyColumn / LazyRow located on the edges were incorrectly positioned after fast fling ( Ie4d13 , b/183877420 )

• Prior to this change, local composable functions were skippable based on their parameters. After this change, no local composable functions will skip. This change is done because it is common and expected for local functions to capture parameters from the parent and them skipping is a common source of bugs.

  To summarize, consider the example:

  @Composable fun Counter(count: Int, onCountChange: (Int) -> Unit) {
    @Composable fun ShowCount() { Text("Count: $count") }
    ShowCount()
    Button(onClick={ onCountChange(count + 1) }) {
      Text("Increment")
    }
  }
  

  Prior to this change, the ShowCount composable function would always skip, even after the count parameter was updated. This is no longer the case. ( I5648a )

Version 1.0.0-beta01

24 февраля 2021 г.

androidx.compose.foundation:foundation:1.0.0-beta01 and androidx.compose.foundation:foundation-layout:1.0.0-beta01 are released. Version 1.0.0-beta01 contains these commits.

This is the first release of Compose 1.0.0 Beta.

API Changes

• onStart callback has been added to detectDragGestures ( I67269 , b/179995594 )
• Modifiers for sizing to intrinsics are no longer experimental. ( I15744 )
• Removed dp assertions ( I798d2 )
• Removed SoftwareKeyboardController callback from all text fields to be replaced by a new API shortly. ( Iae869 , b/168778053 )
• 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 )
• Removed deprecated LayoutCoordinates methods, use function instead of the property for positionInParent and boundsInParent ( I580ed , b/169874631 , b/175142755 )
• 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 )

• Modifier.zoomable has been replaced my Modifier.transformable. smoothPanBy, smoothRotationBy have been added as a functionality. ( Ifc32b , b/175294473 )

• 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 )

• Changed Indication#createIndication() to Indication#rememberUpdatedIndication(InteractionState) and removes InteractionState parameter from I ndicationInstance#drawIndication() . IndicationInstance should only be responsible for drawing visual effects, and not launching animations / writing state in response to InteractionState changes. These animations and state writes should happen within rememberUpdatedIndication() instead. The indication parameter in Modifier.indication was also changed to be a required parameter. ( Ic1764 , b/152525426 )

• Text actions now check focus automatically ( I13777 , b/179648629 )

• Removed runBlockingWithManualClock ( I15cdc , b/179664814 )

• Scroll position in Modifier.verticalScroll()/horizontalScroll() is represented with Ints now ( I81298 )

• smoothScrollBy and scrollBy methods' packages changed to androidx.compose.foundation.gestures.* ( I3f7c1 , b/175294473 )

• FlingConfig has been renamed to FlingBehavior now allows for customization of suspend animation rather than predefined Decays. ( I02b86 , b/175294473 )

• 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 )

• defaultMinSizeConstraints was renamed to defaultMinSize. ( I4eaae )

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

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

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

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

• drawerState.open() and drawerState.close() are now suspending functions. Use rememberCoroutineScope() to get the scope of the composition to call them ( I16f60 , b/175294473 )

• Providers has been renamed to CompositionLocalProvider

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

  • keySourceInfoOf and resetSourceInfo functions have been removed. They are no longer necessary.
  • Composer.collectKeySourceInformation has been removed. It is no longer necessary.
  • isJoinedKey, joinedKeyLeft, and joinedKeyRight methods have been removed. They are no longer necessary.
  • Various top level APIs have been moved and reorganized into different files. Due to Kotlin's file class semantics, this will break binary compatibility but not source compatibility, so should not be an issue for most users.
  • ( I99b7d , b/177245490 )

• Modifier.scrollable has been reworked. Now it uses Scrollable interface instead of ScrollableController class ( I4f5a5 , b/174485541 , b/175294473 )

• Modifier.draggable now accepts DraggableState instead of a simple lambda. you can create state via rememberDraggableState { delta -> } to get the same behaviour as before ( Ica70f , b/175294473 )

• requiredWidth(IntrinsicSize) and requiredHeight(IntrinsicSize) modifiers were added for required sizing to intrinsic sizes. ( I0a6b4 )

• Deprecated emptyContent() is removed. Use {} instead. ( Idb33f , b/179432510 )

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

API Changes

• Modifier.pointerInput now requires remember keys to indicate when the pointer input detection coroutine should restart for new dependencies. ( I849cd )
• Testing update: hasText() will check for both input and label/hint/placeholder texts in the text field ( Iab803 )
• PaddingValues.Absolute was added and can be used in APIs accepting PaddingValues. ( Ia5f30 )
• onImeActionPerformed is deprecated. use KeyboardActions instead ( If0bbd , b/179071523 )
• 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 )
• Introduced an InfiniteAnimationPolicy coroutine context element that will be applied in infinite animations. By default no policy is installed, except when running tests with ComposeTestRule . ( I50ec4 , b/151940543 )
• Animatable.snapTo and Animatable.stop are now suspend functions ( If4288 )
• ComponentActivity.setContent has moved to androidx.activity.compose.setContent in the androidx.activity:activity-compose module. ( Icf416 )
• Destructuring and copy() methods have been removed from several classes where they were rarely used. ( I26702 , b/178659281 )

• Custom keys support for LazyColumn/LazyRow was added. This allows us to smarter handle items reordering. So the state you stored in remember {} blocks will move together with the item when you reorder elements or removed the item from the middle.

  LazyColumn {
      items(users, key = { user -> user.id }) { ... }
  }
  

  • ( Ia50ef , b/164901852 )

• Changed Indication#createInstance to be @Composable, and changed LocalIndication to contain an Indication, not () -> Indication. ( I5eeea , b/157150564 )

• Constraints.enforce was replaced with Constraints.constrain . ( I8b8ea )

• loadFontResource is deprecated. Use fontResource instead. imageResource, loadImageResource, vectorResource, and loadVectorResource are deprecated. Use painterResource instead. ( I6b809 )

• For performance reasons, ScrollAxisRange semantics now takes lambdas returning Floats instead of direct Float values. ( If4a35 , b/178657186 )

• Added EditableText semantics to mark editable input text of the text field for accessibility and corresponding test methods to check the semantics ( I8e07a )

• Modifier.clickable now doesn't have double and long click support. Use Modifier.combinedClickable to achieve this functionality. ( Iafad1 )

• toIntPx() was renamed to roundToPx(). ( I9b7e4 , b/173502290 )

• IntBounds was renamed to IntRect and the API was improved. ( I1f6ff )

• Modifier.dragGestureFilter has been deprecated. Use Modifier.pointerInput { detectDragGestures (...)} instead. Alternatively, use Modifier.draggable for one axis drags ( I0ba93 , b/175294473 )

• Renamed Ambients to match the Ambient -> CompositionLocal rename. Ambients used to be named AmbientFoo, now CompositionLocals are named LocalFoo. ( I2d55d )

• Selection was moved to foundation. ( I7892b )

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

• Added password semantics for accessibility ( I231ce )

• Added ProgressBarRangeInfo.Indeterminate to mark indeterminate progress bars for accessibility ( I6fe05 )

• Playtime in animation is now unfiied to nanoseconds ( If776a )

  @ComposableContract(restartable = false) has become @NonRestartableComposable @ComposableContract(readonly = true) has become @ReadOnlyComposable @ComposableContract(preventCapture = true) has become @DisallowComposableCalls @ComposableContract(tracked = true) has been removed. ( I60a9d )

• emptyContent() and (@Composable () -> Unit).orEmpty() utilities have been deprecated as they no longer have any positive performance impact or value ( I0484d )

• Recomposers can now be closed. Closed recomposers will continue recomposition until composition child coroutines complete. Recomposer.shutDown renamed to cancel to contrast with close. ( Ib6d76 )

• APIs related to LazyVerticalGrid are marked as experimental ( Ia53e3 , b/178519862 )

• rememberSavedInstanceState() was renamed to rememberSaveable() and moved to androidx.compose.runtime.saveable package. ( I1366e , b/177338004 )

• RestorableStateHolder was renamed to SaveableStateHolder and moved to androidx.compose.runtime.saveable package. Inner method RestorableStateProvider was renamed to SaveableStateProvider. Generic type was removed so you can just pass Any as a key. Experimental annotation is not needed anymore. ( I0902e , b/174598702 )

• Saver, listSaver(), mapSaver(), autoSaver was moved from androidx.compose.runtime.savedinstancestate to androidx.compose.runtime.saveable ( I77fe6 )

• Artefact androidx:compose:runtime:runtime-saved-instance-state was renamed to androidx:compose:runtime:runtime-saveable ( I6dcac )

• Many longstanding deprecated APIs in the ui package are deleted. ( I2f2dc )

• The compose:runtime-dispatch artifact is now deprecated. MonotonicFrameClock can now be found in compose:runtime and AndroidUiDispatcher can be found in compose:ui. ( Ib5c36 )

• Parameters on RounderCornerShape, CutCornerShape and CornerBasedShape were renamed from left/right to start/end in order to support the shape's auto mirroring in the rtl direction. AbsoluteRounderCornerShape and AbsoluteCutCornerShape were introduced for the cases when auto-mirroring is not desired. ( I61040 , b/152756983 )

• canDrag has been removed from the Modifier.scrollable. ( Id66e7 , b/175294473 )

• 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 )

• Modifier.scaleGestureFilter has been removed. Use Modifier.zoomable instead. Alternatively, use Modifier.pointerInput { detectMultitouchGestures { ... }} ( Id5da1 , b/175294473 )

• AnimatedValue/Float is now deprecated. Please use Animatable instead. ( I71345 , b/177457083 )

• • Removed CoreText and CoreTextField from public API
  • Removed deprecated SelectionContainer overload ( I99c19 )

• Remove deprecated non-suspend scrolling functions Continuing with the changes from last release, the non-suspend scrolling functions are now removed entirely. Please convert to the suspend functions with the same names. A coroutine scope can be obtained via rememberCoroutineScope(). ( I3d39c , b/178169563 )

• androidx.compose.foundation.layout.ConstraintLayout was deprecated in favor of androidx.constraintlayout.compose.ConstraintLayout. You will need to add a dependency on androidx.constraintlayout:constraintlayout-compose:1.0.0-alpha01 . ( I87adc )

• Removed Recomposer.current() . [Abstract]ComposeView now default to lazily created, window-scoped Recomposers driven by the ViewTreeLifecycleOwner for the window. Recomposition and withFrameNanos-based animation ticks are paused while the host Lifecycle is stopped. ( I38e11 )

• Recomposer.runningRecomposers now offers a global StateFlow of read-only RecomposerInfo for observing ongoing composition state in the process. Prefer this API to Recomposer.current(), which is now deprecated. ( If8ebe )

Version 1.0.0-alpha11

28 января 2021 г.

androidx.compose.foundation:foundation:1.0.0-alpha11 and androidx.compose.foundation:foundation-layout:1.0.0-alpha11 are released. Version 1.0.0-alpha11 contains these commits.

API Changes

• Deprecate non-suspend scrollBy, remove non-suspend scrollTo

  We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating and/or removing the non-suspend versions of these functions as part of this transition. ( Ie9ced )

• Deprecate non-suspend smoothScrollBy We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating the non-suspend versions of these functions as part of this transition. ( I12880 )

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

• BasicTextField received a new parameter called 'decorationBox'. It allows to add the decorations like icons, placeholder, label and similar to the text field and increase the hit target area of it. ( I16996 )

• canDrag parameter has been removed from the Modifier.draggable ( Ic4bec , b/175294473 )

• AnimatedFloat.fling that accepts FlingConfig has been removed. Please use suspend Animatable.animateDecay instead. ( I4659b , b/177457083 )

• Removed data class from the following classes:

  • InlineTextContent
  • LocaleList
  • ( I605c7 )

• clickable, toggleable and selectable can be created outside of composition now ( I0a130 , b/172938345 , b/175294473 )

• ScrollableColumn/Row were deprecated. Using ScrollableColumn is less efficient comparing 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 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 )

• The deprecated AbsoluteArrangement was removed. ( Iffa96 , b/177641870 )

• The propagateMinConstraints parameter was added to Box, for specifying whether the incoming min constraints should be passed to the content of the Box or not. Default is false. ( I0125b , b/152613457 )

Исправления ошибок

• onCommit, onDispose, and onActive have been deprecated in favor of SideEffect and DisposableEffect APIs ( If760e )
• WithConstraints was reworked as BoxWithConstraints and moved to foundation.layout. ( I9420b , b/173387208 )

• 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 )

• Density is now receiver scope for Arrangement interfaces. ( I18aad )

• 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 )

• Duration and Uptime will be replace with Long milliseconds, and this step removes the dependency of pointer input on those classes. ( Ia33b2 , b/175142755 , b/177420019 )

• 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 )

Version 1.0.0-alpha09

16 декабря 2020 г.

androidx.compose.foundation:foundation:1.0.0-alpha09 and androidx.compose.foundation:foundation-layout:1.0.0-alpha09 are released. Version 1.0.0-alpha09 contains these commits.

API Changes

• Add Scrollable interface

  This allows ScrollState and LazyListState to be treated as a common type, allowing custom scrolling to be implemented across both types.

  This also moves smoothScrollBy to an extension function on Scrollable, taking advantage of this functionality. ( I2153b )

• LazyVerticalGrid is added. ( I17267 , b/162213211 )

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

• For suspending pointer input APIs, renamed HandlePointerInputScope to AwaitPointerEventScope and handlePointerInput() to awaitPointerEventScope(). ( Idf0a1 , b/175142755 )

• LazyListState.layoutInfo was added which exposes the list of sizes and offsets of the currently visible items ( If8678 , b/170472532 )

• Removed ExperimentalPointerInput annotation ( Ia7a24 )

• InteractionState support for TextFields has been added. ( I61d91 )

• Add reverseLayout param for LazyColumn/Row. when true items will be composed from the bottom to the top and LazyListState.firstVisibleItemIndex == 0 will mean the first item is located at the bottom. ( I552ae , b/166589935 )

• verticalArrangement param was added for LazyColumn. horizontalArrangement param was added for LazyRow. Arrangement allows us to add a spacing between items and specify the arrangement of the items when we do not have enough of them to fill the whole minimum size. ( Icf79a , b/170394300 )

• detectMultitouchGestures now uses one callback with combined centroid, pan, zoom and rotate parameters. ( Ie6e1c )

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

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 )

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

• AndroidOwner made internal ( Ibcad0 , b/170296980 )

• New infiniteRepeatable function for creating an InfiniteRepeatableSpec ( I668e5 )

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

API Changes

• CoreTextField now supports cursor functionality ( Id23aa )

• Deprecates contentColor() and currentTextStyle() APIs, and replaces them with AmbientContentColor and AmbientTextStyle ambients respectively. You can access the current value by using .current on the ambient property, as with any other ambient. This was change was made for consistency and to avoid having multiple ways to accomplish the same thing. Additionally renames some ambient properties to better describe their purpose as follows:

API Changes

• Stack was renamed to Box. The previously existing foundation.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 )
• Add a new LazyListState class. This allows for observation and control of the scroll position of LazyRow and LazyColumn components. Instances can be created using rememberLazyListState() and passed into the state parameter of the component. Currently, the first visible item and offsets can be observed in this initial version. ( Ic7cb7 , b/159307669 )
• Lazy list position and scroll offset are now saved and restored across Activity recreation ( Ie045f , b/166589058 )
• Add long click semantics action ( I6281b , b/156468846 )
• MutatorMutex utility added for keeping a single mutator of shared state over time and cancelling conflicting mutators by priority ( I3f975 )
• Annotated rootAnimationClockFactory, transitionsEnabled, blinkingCursorEnabled and textInputServiceFactory with @VisibleForTesting, make them internal API and hide their kdoc ( I554eb , b/168308412 )
• Removed inlineContent parameter from Text with String input. It won't be used because inlineContent must work with AnnotatedString. ( Ief403 )
• The deprecated custom Arrangement APIs were removed. ( Ic576d , b/168297922 , b/168297923 )
• The unbounded parameter was added to wrapContentSize modifiers, which enables measuring the layout element with infinite max constraints. ( I77951 , b/158559319 )
• We prevented static imports of contents of layout scopes (eg alignWithSiblings in RowScope). The explicit scope alternative should be used instead: with(RowScope) { Modifier.alignWithSiblings(FirstBaseline) } . ( I216be , b/166760797 )

Исправления ошибок

  • Added a destructing API to Radius
  • Migrated various RoundRect extension functions to be properties instead
  • ( I8f5c7 , b/168762961 )
• Performance optimizations for LazyColumnFor/LazyRowFor scrolling by not doing unnecessary recompositions during every scroll ( I64f65 , b/168293643 , b/167972292 , b/165028371 )
• Fixed crash in LazyColumnFor/LazyRowFor after scrolling and then changing items and implemented auto scrolling up when the previously visible item was removed so we don't display empty gaps in the end anymore ( I220ab , b/161480164 , b/167855468 )
• Nesting scrollable in the same direction containers like ScrollableContainer and LazyColumnFor is not allowed anymore. It was never supported and was breaking the fling and all the laziness of composing the items of LazyColumnFor ( I6e101 )
• Updated many Graphics APIs
  • Updated DrawScope APIs with scoped transformation methods to indicate that the transformation is only applied within the callback and removed after the callback is invoked
  • Updated clipPath documentation to refer to Path instead of rounded rectangle

  @Test
  fun myTest() = runWithManualClock { clock ->
      // set some compose content
      withContext(TestUiDispatcher.Main) {
          clock.advanceClock(1000L)

API Changes

• The spacedBy Arrangement was added for Row and Column, to enable positioning layout children with a fixed spacing. The aligned Arrangment was also added, to enable positioning layout children one next to the other and aligned in the Row/Column according to an Alignment. The previous Arrangement.Vertical#arrange and Arrangement.Horizontal#arrange methods were deprecated, and writing custom Arrangements will not be supported in the future. ( I6733d , b/161985975 )
• Offset has become an inline class ( Iaec70 )
• Removed onFocusChanged callbacks from TextField. Use Modifier.focusObserver instead. ( I51089 , b/161297615 )
• Modifier.drawBorder has been deprecated. Use Modifier.border instead. Border data class has been replaced by BorderStroke ( I4257d , b/158160576 )
• VerticalScroller and HorizontalScroller have been removed. Use ScrollableColumn/Row instead. Modifier.drawBackground has been removed. Use Modifier.background ( I73b0d , b/163019183 )
• Remove marked as deprecated fillMax* modifiers from LazyItemScope as they are making it harder to add such modifiers correctly for items which are not direct children of LazyColumnFor ( Ifa78d )
• added LazyColumn/LazyRow implementation as DSL ( I93cc6 )
• Constraints is now an inline class ( I88736 )
• Added the ability to size a layout to a fraction of the available space, using the fillMaxWidth, fillMaxHeight and fillMaxSize modifiers. ( I945bb , b/161562591 )

Исправления ошибок

• Added a modifier param to SelectionContainer ( I4aada , b/161487952 )
• Added mergePolicy lambda to SemanticsPropertyKey. This can be used to define a custom policy for mergeAllDescendants semantics merging. The default policy is to use the parent value if already present, otherwise the child value. ( Iaf6c4 , b/161979921 )
• PlacementScope.placeAbsolute() was renamed to PlacementScope.place() , and the previous PlacementScope.place() was renamed to PlacementScope.placeRelative() . As a result, the PlacementScope.place() method will not automatically mirror the position in right-to-left contexts anymore. If this is desired, use PlacementScope.placeRelative() instead. ( I873ac , b/162916675 )
• Removed deprecated FilledTextField component. Please use TextField instead to get the Material Design implementation of the Filled text field. ( I5e889 )
• Added backgroundColor parameter to LinearProgressIndicator and removed internal padding from CircularProgressIndicator. Added new ProgressIndicatorConstants.DefaultProgressAnimationSpec which can be used as the default AnimationSpec when animating progress between values ( If38b5 , b/161809914 , b/161804677 )
• The state { ... } composable is now deprecated in favor of explicit calls to remember { mutableStateOf(...) } for clarity. This reduces the overall API surface and number of concepts for state management, and matches the by mutableStateOf() pattern for class property delegation. ( Ia5727 )
• Renamed RRect to RoundRect to better fit compose naming patterns Created similar function constructors to RRect and deprecated RRect function constructors ( I5d325 )
• Removed onChildPositioned and OnChildPositionedModifier. Developers should use onPositioned and OnPositionedModifier on the child layout instead. ( I4522e , b/162109766 )

Version 0.1.0-dev16

5 августа 2020 г.

androidx.compose.foundation:foundation:0.1.0-dev16 , androidx.compose.foundation:foundation-layout:0.1.0-dev16 , and androidx.compose.foundation:foundation-text:0.1.0-dev16 are released. Version 0.1.0-dev16 contains these commits.

API Changes

• LazyItemScope was added for itemContent param of Lazy lists. It provides modifiers to fill the parent max size which solves the use case when the item should fill the viewport and the regular Modifier.fillMaxSize() doesn't work as the item is measured with infinity constraints. ( Ibd3b2 , b/162248854 )
• Move dialog to ui ( I47fa6 )
• Added LazyColumnForIndexed/LazyRowForIndexed - versions of LazyColumnFor/LazyRowFor which provides both index and item in the itemCallback. It is useful when in addition to a current item you need to know a current index. ( I65ff3 )
• Modifier.deternimateProgress has been renamed to Modifier.progressSemantics ( I9c0b4 )
• LazyColumnItems was renamed to LazyColumnFor. LazyRowItems was renamed to LazyRowFor ( I84f84 )
• Add some Marks/Annotations for best practice reason. ( I66b20 )
• foundation.shape.corner package were flatten to foundation.share ( I46491 , b/161887429 )
• Added сrossaxis gravity param for LazyRowItems/LazyColumnItems. LazyRowItems/LazyColumnItems now support wrap content behaviour. ( Ib39fc )
• ZoomableState has been renamed to ZoomableController. Custom curve support has been added for smoothScale. enabled and onZoomStarted functionality has been added ( If8b8f )
• Material FilledTextField was renamed to TextField and foundational TextField was renamed to BaseTextField to make simplest desired API easy to discover and use ( Ia6242 , b/155482676 )
• Previously deprecated AdapterList has been removed. Use LazyColumnItems instead ( I12b9b )
• Modifier.drawBackground has been renamed to Modifier.background ( I13677 )
• The old ConstraintLayout DSL was removed. ConstraintSet2 has been renamed to ConstraintSet. ( If58d1 , b/162450908 )
• Added Modifier.absoluteOffset() and Modifier.absoluteOffsetPx(). Unlike offset modifiers, absolute offset modifiers will not auto-mirror in right-to-left context ( I3aa21 )
• Row and Column are now inline function significantly reducing the overhead of using them. ( I75c10 )

Исправления ошибок

• Address broad API fixes ( I077bc )
  1. Remove unused OffsetBase interface
  2. Align Offset and IntOffset classes to have a consistent API surface
  3. Rename IntOffset.Origin to IntOffset.Zero to be consistent with Offset API
  4. Moved nativeCanvas method off of Canvas interface to support consumers to create their own Canvas instances
  5. Created stub EmptyCanvas class to refactor DrawScope to be a non-null parameter instead of lateinit and ensure non-nullability of the field
  6. Renamed ClipOp enums to be Pascal Case
  7. Renamed FilterQuality enums to be Pascal Case
  8. Renamed StrokeJoin enums to be Pascal Case
  9. Renamed PointMode enums to be Pascal Case
  10. Renamed PaintingStyle enums to be Pascal Case
  11. Renamed PathFillType enums to be Pascal Case
  12. Renamed StrokeCap enums to be Pascal Case
  13. Updated DrawCache implementation to no longer use lateinit params
  14. Updated DrawScope to no longer use lazy delegation for fillPaint and strokePaint internal parameters
  15. Updated Image composable to avoid Box usage for less overhead
  16. Updated Outline class to have @Immutable annotations
  17. Updated PathNode to have @Immutable annotations for each path instruction
  18. Updated Vector subcomposition to remove redundant conditional checks for equality as compose already handles them
  19. Deprecated Rect companion constructor methods in favor of function constructors
  20. Updated Brush classes and function constructors with @Immutable and @Stable APIs
  21. Updated VertexMode enum to be PascalCase
  22. Updated DrawScope selectPaint method to conditionally overwrite stroke parameters on the paint if they have changed
  23. Updated Size to add destructuring API, rename UnspecifiedSize to Unspecified and removed unused methods

• Added MonotonicFrameAnimationClock that enables you to use a MonotonicFrameClock as an AnimationClockObservable to bridge the gap between the new coroutines based clocks and APIs that still use the old callback based clocks.

  The MonotonicFrameClock equivalent of ManualAnimationClock is now ManualFrameClock. ( I111c7 , b/161247083 )

• Removed SemanticsNodeInteraction.performPartialGesture . Use SemanticsNodeInteraction.performGesture instead. ( Id9b62 )

• Renamed SemanticsNodeInteraction.getBoundsInRoot() to SemanticsNodeInteraction.getUnclippedBoundsInRoot() ( Icafdf , b/161336532 )

• The APIs for right-to-left support has been updated. LayoutDirectionAmbient has been added, which can be used to read and change the layout direction. Modifier.rtl and Modifier.ltr have been removed. ( I080b3 )

• Modifier.plus has been deprecated, use Modifier.then instead. 'Then' has a stronger signal of ordering, while also prohibits to type Modifier.padding().background() + anotherModifier , which breaks the chain and harder to read ( Iedd58 , b/161529964 )

• Added isFocused() and isNotFocused() SemanticsMatcher. ( I0b760 )

• RemeasurementModifier was added. It allows users to synchronously remeasure the layout. In general, you never need it as remeasure/relayout is happening automatically, but we use it inside LazyColumnItems during the scroll. ( I5f331 , b/160791058 )

• isSystemInDarkTheme now always considers the system-wide dark theme setting, and ignores power saving status before Q, following latest guidance. ( I0c10c )

• OnChildPositioned has been deprecated. Use OnPositioned on the child instead. ( I87f95 , b/162109766 )

• Renamed AndroidComposeTestRule to createAndroidComposeRule. ( I70aaf )

• Add accessibility action to get TextLayoutResult ( I9d6e6 )

Version 0.1.0-dev15

22 июля 2020 г.

androidx.compose.foundation:foundation:0.1.0-dev15 , androidx.compose.foundation:foundation-layout:0.1.0-dev15 , and androidx.compose.foundation:foundation-text:0.1.0-dev15 are released. Version 0.1.0-dev15 contains these commits.

To use the 0.1.0-dev15 version of Compose, you will need to:

Dependencies Update

• To use the 0.1.0-dev15 version of Compose, you will need to update your dependencies according to the new code snippets shown above in Declaring dependencies .

API Changes

• Similarly to the new param in ScrollableColumn/ScrollableRow LazyColumnItems/LazyRowItems now also have contentPadding param which allows to add a padding for the content after it has been clipped, which is not possible via just a modifier param. It also allows to add a spacing only before first item/after last item. ( Ibc24e )
• onFocusChange callback in text fields renamed to onFocusChanged ( Ida4a1 )
• VerticalScroller and HoriziontalScroller have been deprecated. Use ScrollableColumn and ScrollableRow for build-in experience with Column/Row behaviour and parameters, or Modifier.verticalScroll and Modifier.horizontalScroll on your own element. Similarly, ScrollerPosition has been deprecated in favor of ScrollState' ( I400ce , b/157225838 , b/149460415 , b/154105299 )
• Modifier.draggable and Modifier.scrollable APIs were reworked. DragDirection was removed in favor of Orientation. State required for scrollable has beed simplified. ScrollableState has been renamed to ScrollableController ( Iab63c , b/149460415 )
• Single-value semantics properties now use a calling style. For example, 'semantics { hidden = true }' is now written as: semantics { hidden() } . ( Ic1afd , b/145951226 , b/145955412 )
• Corner sizes used by RoundedCornerShape and CutCornerShape can now be larger than 50% ( Id2340 , b/160400213 )
• Changed the default ContentScale parameter for the Image composable from Inside to Fit. This was done in order to get behavior to scale up the underlying Painter if the layout size is larger than the intrinsic size of the painter while maintaining the aspect ratio. This behavior better matches expectations for providing fixed sizes to the Image while not affecting the default behavior if only the intrinsic size is used to compute the size of the composable. ( I40ae3 , b/159838006 )
• Use AnimationSpec instead of AnimationBuilder in the top level APIs to clarify the concept of static animation specification -Improve the transition DSL by removing the lambda requirement for creating AnimationSpecs such as tween, spring. They instead take constructor params directly. -Improve the overall ease of use of AnimationSpec opening up constructors instead of relying on builders -Change the duration and delay for KeyFrames and Tween to Int. This eliminates unnecessary type casts and method overloading (for supporting both Long and Int). ( Ica0b4 )
• Clickable was removed. Use Modifier.clickable ( I84bdf )
• Added LazyRowItems - Horizontally scrolling analogue of LazyColumnItems ( Ibbcf7 )
• Introduced low level stateless animation APIs. These APIs ( I63bf7 )
• androidx.ui.foundation.TextFieldValue and androidx.ui.input.EditorValue is deprecated. TextField, FilledTextField and CoreTextField composables that uses that type is also deprecated. Please use androidx.ui.input.TextFieldValue instead ( I4066d , b/155211005 )
• Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. ( Ib7b44 )
• androidx.ui.foundation.shape.RectangleShape removed; use androidx.ui.graphics.RectangleShape ( I94939 , b/154507984 )
• In order to consolidate the number of classes used to represent sizing information, standardize on usage of the Size class instead of PxSize. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent width and height represented as floats. ( Ic0191 )
• In order to consolidate the number of classes used to represent positioning information, standardize on usage of the Offset class instead of PxPosition. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent x and y offsets represented as floats. ( I3ad98 )
• Added Modifier.zoomable for pinch-to-zoom functionality ( Id5d63 )
• Toggleable component has been deprecated. Use Modifier.toggleable instead ( I35220 , b/157642842 )
• MutuallyExclusiveSetItem has been deprecated. Use Modifier.selectable instead. ( I02b47 , b/157642842 )
• TestTag is now deprecated. Use Modifier.testTag instead. ( If5110 , b/157173105 )
• Adds fontWeight parameter to Text, which was accidentally not added previously ( I56937 )
• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I19d02 )
• VerticalScroller now provides Column out of the box. HorizontalScroller now provides Row out of the box. ( Ieca5d , b/157020670 )
• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( Iede0b )
• Modifier.indication has been added to foundation package. Use it to show press/drag/other indication on your custom interactable elements ( I8425f , b/155287131 )
• VerticalScroller and HorizontalScroller now support reversed scrolling is isReversed is set on ScrollerPosition ( I953bd )
• Support adding composables into text layout. ( I1373c )
• Consolidated CanvasScope implementations so there is now just DrawScope and ContentDrawScope Renamed CanvasScope to DrawScope. Updated DrawScope to implement Density interface and provide LayoutDirection Deleted DrawScope subclass in ContentDrawScope Painter and PainterModifier have been updated to no longer maintain an RTL property themselves as DrawScope provides this already without manually providing it ( I1798e )
• Removed deprecated DrawBackground API in favor of drawBackground extension APIs on Modifier. Refactored color, brush and paint drawBackground implementations to reduce code paths as well as remove requirement for Modifier to be created as part of composition. ( I0343a )
• Updated higher level compose APIs that expose a Canvas to expose CanvasScope instead. This removes the need for consumers to maintain their own Paint objects. For consumers that still require access to a Canvas they can use the drawCanvas extension method which provides a callback to issue drawing commands with the underlying Canvas. ( I80afd )
• HorizontalScroller and VerticalScroller not restores their scroll position using saved instance state. ( Ia0fae , b/155075048 )
• FocusManagerAmbient is removed. Use FocusModifier.requestFocus to obtain focus. ( Ic4826 )
• Table layout was removed temporarily until we will make it available again with a refreshed API. ( Id88a7 )

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

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

• ColoredRect has been removed. User Box with drawBackground modifier instead ( I983c7 , b/152753731 )

• Add cursor color customisation to the TextField ( I6e33f )

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

• TextFieldValue used with TextField can now be survive activity recreation when used like this: var text by savedInstanceState(saver = TextFieldValue.Saver) { TextFieldValue() } ( I5c3ce , b/155075724 )

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

• Replaced CoreTextField/TextField focusIdentifier parameter with FocusNode in order to integrate with focus subsystem. ( I7ea48 )

• TextField update - in horizontal dimension it will occupy all available space granted to it ( Ib08df , b/154638552 )

• Added InteractionState and Interaction, making it easier to build components that react to UI state changes such as press, and drag ( Icfe25 , b/152525426 )

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

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

• TextField API update - merged onFocus and onBlur callbacks into a single onFocusChange(Boolean) callback with parameter ( I66cd3 )

• Renamed ScaleFit to ContentScale Moved ContentScale from ui-graphics to ui-core module to live in the same module as the Alignment API. Renamed FillMaxDimension to Crop Renamed FillMinDimension to Fit Renamed Fit to Inside to better match ImageView.ScaleType equivalents Added documentation indicating that the combination of Crop and Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_CROP and Fit used with Alignment.Center achieves the same result as ImageView.ScaleType.FIT_CENTER Inside used with Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_INSIDE ( I45f09 , b/152842521 )

• Removes ProvideContentColor, instead just use ContentColorAmbient directly with Providers ( Iee942 )

• Adds color parameter to text, allowing overriding the color of the text style without needing to manually merge with the style provided in a theme. ( I41a66 )

• Improve DrawModifier API:

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

• ColoredRect has been deprecated. Use Box(Modifier.preferredSize(width, height).drawBackground(color)) instead. ( I499fa , b/152753731 )

• Shape theming system is updated according to the Material design specification. Now you can provide small, medium and large shapes to be used by most of the components ( Ifb4d1 )

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

• Draggable has been moved to modifier ( Id9b16 , b/151959544 )

• Moved Text to androidx.ui.foundation package, from androidx.ui.core. ( I87ce5 )

• add enabled param to Checkbox, Switch and Toggleable ( I41c16 )

• Ripple is now a Modifier. While Clickable is not yet converted the recommended usage is Clickable(onClick = { ... }, modifier = ripple()) ( Ie5200 , b/151331852 , b/150060763 )

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

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

• Created Image composable to handle sizing/layout in addition to drawing a given ImageAsset to the screen. This composable also supports drawing any arbitrary Painter instance respecting its intrinsic size as well as supporting a given fixed size or minimum size ( Ibcc8f )

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

• Renamed Image to ImageAsset to better differentiate the difference between the Image data and the upcoming Image composable used to participate in layout and draw content.

  Created extension method on android.graphics.Bitmap, Bitmap.asImageAsset() , to create an instance of an ImageAsset useful for combining traditional Android application development with the compose framework. ( Id5bbd )

• DrawImage composable was removed. Use ImagePainter to draw image on existing layout, or SimpleImage to introduce Image that takes space ( I595e1 , b/149827027 )

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

• Added Icon, IconButton and IconToggleButton, removing AppBarIcon. You can directly replace existing usages of AppBarIcon with IconButton, and they will now have the correct touch target. See the samples for usage information, and see Icons for the provided Material Icons you can use directly with these components. ( I96849 )

• DrawShape composable was removed. Use DrawBackground modifier instead. ( I7ceb2 )

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

• Scrollable component has been added, which allows creation of custom Scrollers/Lists ( I5fd37 )

• Renamed background to DrawBackground and make it to be memorized by default ( Ia0bd3 )

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

• rename Border modifier to DrawBorder ( I8ffcc )

• Added Box component for combining layout and drawing common functionality. ( I6e2a7 )

• Scrollers now exhibit native Android fling motion behavior. ( I922af , b/147493715 )

• Replaced DrawBorder in favor of Border Modifier ( Id335a )

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

• The percent parameter when creating ConstraintLayout guidelines has been renamed to fraction. ( Ida2db )

• Added support for margins of ConstraintLayout barriers. ( I47ffe )

• Fixed RTL support in ConstraintLayout. Added RTL unaware APIs. ( I3b1c7 )

• A new DSL for ConstraintLayout has been added. Please see the samples for more details. ( Icaa9a )

• Added the @ExperimentalLayout annotation. ConstraintLayout, FlowRow and FlowColumn are now tagged with it to mark that their APIs are going to change. ( I412a8 )

• Modifier.padding(InnerPadding) has been added ( I94985 , b/157133803 )

• Removed deprecated RowAlign, ColumnAlign in Row and Column. ( If60d4 , b/155858731 )

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

• Added the offsetPx layout modifier, which can be used to define (dynamic) offsets in px. ( I5af57 )

• AlignmentLineOffset composable is deprecated, please use relativePaddingFrom() modifier instead. CenterAlignmentLine composable is removed. ( I60107 )

• Added defaultMinSizeConstraints layout modifier, which sets size constraints to the wrapped layout only when the incoming corresponding constraints are unspecified (0 for min constraints and infinity for max constraints). ( I311ea , b/150460257 )

• Container has been removed. Use Box instead ( Ibbc2b , b/151407926 )

• Removed deprecated LayoutWidth/Height/Size modifiers. ( Ib0bc1 )

• Added default parameter values for the offset modifier. ( I37f06 )

• Added symmetric padding modifier. ( I39840 )

• Removed deprecated LayoutAspectRatio modifier. ( I65a74 )

• Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. ( I7f164 )
• Removes previously deprecated Modifier.ripple. Clickable now uses ripple as the default indication (if you have a MaterialTheme {} set in your application) so in most cases you can just use clickable and get ripple indication for free. If you need to customize the color / size / bounded parameter for the ripple, you can manually create a RippleIndication and pass it to clickable as the indication parameter. ( I663b2 , b/155375067 )

• @Untracked annotation has been deprecated. Replace with @ComposableContract(tracked=false) ( Id211e )
• Prior to this change, the compose compiler plugin would non-trivially intercept calls to constructors inside of a @Composable function if there was an ( I5205a , b/158123804 )
• Add viewModel() composable which allows to create or get already created ViewModel similarly to how it works in Activity or Fragment ( I5fdd1 )

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

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

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

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

• Fixed a crash in AdapterList when removing items ( Ic64b0 , b/153195921 )

• We changed how we measure the first layout you put inside activity.setContent { } block. Previously it was forced to fill the whole activity screen, and now it behaves as if you put your layout inside a Stack: it can be smaller than a screen and will be positioned in the top left screen. If you want the old behaviour you can apply Modifier.fillMaxSize() for your layout. ( Ie88a7 , b/153453714 )

• ui-text-compose module is renamed as ui-text. ui-text now contains CoreText and CoreTextField composables ( Ib7d47 )

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

• Moved ui-framework/CoreText, CoreTextField composables under ui-text-compose. You might want to include ui-text-compose in your project. ( I32042 )

• runOnIdleCompose and runOnUiThread are now global functions instead of methods on ComposeTestRule. ( Icbe8f )

• [Mutable]State property delegate operators moved to extensions to support Kotlin 1.4 property delegate optimizations. Callers must add imports to continue using by state { ... } or by mutableStateOf(...) . ( I5312c )

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

• Renamed LayoutFlexible to LayoutWeight. Renamed tight parameter to fill. ( If4738 )

• DrawVector has been changed from a regular composable function to returning a Modifier drawVector() that will draw the vector as a background to a layout. ( I7b8e0 )

• Replace composable function Clip with modifier drawClip(). DrawClipToBounds is a convenient modifier to use when you only need to clip to the layer bounds with a rectangle shape. ( If28eb )

• Replaced DrawShadow composable function with drawShadow() modifier. Shadows are now drawn as part of LayerModifier. ( I0317a )

• androidx.compose.ViewComposer has been moved to androidx.ui.node.UiComposer androidx.compose.Emittable has been removed. It was redundant with ComponentNode. androidx.compose.ViewAdapters has been removed. They are no longer a supported use case. Compose.composeInto has been deprecated. Use setContent or setViewContent instead. Compose.disposeComposition has been deprecated. Use the dispose method on the Composition returned by setContent instead. androidx.compose.Compose.subcomposeInto has moved to androidx.ui.core.subcomposeInto ComponentNode#emitInsertAt has been renamed to ComponentNode#insertAt ComponentNode#emitRemoveAt has been renamed to ComponentNode#removeAt ComponentNode#emitMode has been renamed to ComponentNode#move ( Idef00 )

• Deprecated Wrap composable. It can be replaced either with the LayoutAlign modifier or with the Stack composable ( Ib237f )

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

• Rename Painter.toModifier to Painter.asModifier as the newly created Modifier has a reference to the original Painter that can be shared across multiple Modifier instances ( I7195b )

• Support right-to-left direction in LayoutPadding modifier ( I9e8da )

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

• Removed ValueHolder class. Restructured AnimatedValue, AnimatedFloat classes to make the animation value field abstract so that subclasses can watch the value update.

  • Added model classes for AnimatedValue, AnimatedFloat, etc.
  • Added a new set of light-weight @Composable API for animating between values.
  • ( I79530 )

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

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

• Fixed a ConstraintLayout bug causing a crash on recompositions. ( Ibee5a , b/158164341 )

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

• Renamed LayoutModifier2 to LayoutModifier. ( Id29f3 )

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

• LayoutDirectionAmbient is deprecated. To read the layout direction defined by the locale, use localeLayoutDirection on ConfigurationAmbient ( I851b1 )

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

• ParentData composable is deprecated. You should either create a modifier which implements ParentDataModifier interface, or use LayoutTag modifier if you simply need to tag layout children to recognize them inside the measure block. ( I51368 , b/150953183 )

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

• Disallow negative padding in LayoutPadding. LayoutOffset should be used instead for negative position offsets. ( Ifb5b1 )

• WithConstraints got LayoutDirection parameter ( I6d6f7 )

• Updated the ComposeFlags.COMPOSER_PARAM flag to be true , which will change the code generation strategy for the compose plugin. At a high level, this causes @Composable functions to be generated with an additional synthetic parameter, which is passed through to subsequent @Composable calls in order for the runtime to properly manage execution. This is a significant binary breaking change, however, should preserve source-level compatibility in all sanctioned usage of compose. ( I7971c )

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

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

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

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

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

• Add Toolbar for text related operations. ( I49d53 )

• New LifecycleOwnerAmbient is now available. Now an Activity you are using with Compose UI should extend androidx.activity.ComponentActivity (or AppCompatActivity). setContent on android.app.Activity is now deprecated ( Idb25a , b/153141084 )

• ui-android-text package name (androidx.text) replaced with androidx.ui.text.platform in order to align with androidx policy. ( I42711 )
