Wear Compose версии 1.6

Версия 1.6.0-альфа04

22 октября 2025 г.

Выпущена androidx.wear.compose:compose-*:1.6.0-alpha04 . Версия 1.6.0-alpha04 содержит следующие коммиты .

Изменения API

• Реализовать reverseLayout для TransformingLazyColumn ( I19f9e , b/352513793 )
• Добавлен ConfirmationDialogDefaults.VariantFailureIcon для использования в FailureConfirmationDialog . Этот новый универсальный значок ошибки может быть предпочтительнее в некоторых случаях по сравнению с ConfirmationDialogDefaults.FailureIcon , который показывает разрыв соединения с телефоном. ( Ifc851 , b/443115305 )

Исправления ошибок

• Улучшена производительность Picker за счет рефакторинга использования LaunchedEffect . ( I94519 , b/418192973 )
• Исправлена ​​ошибка в SwipeDismissableNavHost в API36+, из-за которой нажатие кнопки «Назад» во время предиктивной анимации «Назад» прерывало и запускало её заново. Теперь реализация использует SeakableTransitionState.animateTo вместо Animatable, что обеспечивает небольшой выигрыш в производительности. ( I2241f , b/428156670 )
• Исправлена ​​ошибка в порядке объявлений доступности в AlertDialog , из-за которой кнопка подтверждения объявлялась как «Кнопка. Подтвердить», а не как стандартная «Кнопка. Подтвердить». ( Ic2381 , b/429378202 )
• Улучшена видимость номера TimePicker на маленьких экранах. ( I68386 , b/447625365 )
• Удален форк Lazy Layout из Wear Compose Foundation. Это означает, что TransformingLazyColumn теперь использует реализацию Compose Foundation Lazy Layout, включая предварительную выборку, и в большинстве случаев выигрывает от повышения производительности по времени кадра. ( Idd743 , b/445911630 )

Версия 1.6.0-альфа03

8 октября 2025 г.

Выпущена androidx.wear.compose:compose-*:1.6.0-alpha03 . Версия 1.6.0-alpha03 содержит следующие коммиты .

• Удален неиспользуемый параметр targetProgress в методе drawCircularProgressIndicator CircularProgressIndicator ( Ieeb3c , b/430544552 )

Исправления ошибок

• Реализована отсутствующая поддержка TransformingLazyColumn verticalAlignment — теперь поддерживаются стандартные расположения по верху, низу или по центру. ( I2e630 , b/444143326 )
• Улучшить расчет ширины изогнутого текста с учетом пробелов до и после текста (может привести к сбою снимков экрана, содержащих изогнутый текст, особенно если у него есть фон, такой как TimeText ). ( I924a4 , b/446601899 )
• Обновленный Compose Foundation WarpedCurvedTextRenderer теперь использует EmojiCompatInitializer из androidx.emoji2 для исправления ошибки класса во время выполнения. ( I589b4 , b/444422736 )
• Обновлен ScalingLazyColumn для фокусировки на прокручиваемом узле с CollectionInfo , чтобы он работал с поворотным элементом в большем количестве контекстов, например в Material3 AlertDialog . ( I6be3c , b/445332360 )

Версия 1.6.0-альфа02

24 сентября 2025 г.

Изменения API

• Улучшена визуализация изогнутого текста, особенно для курсивных шрифтов, благодаря внедрению деформации текста с использованием нового параметра CurvedTextStyle warpOffset . ( If5dcb )

Исправления ошибок

• Оптимизировано кэширование анимации элементов во время прокрутки в TransformingLazyColumn . ( I62ae8 )
• Варианты OpenOnPhoneDialog и ConfirmationDialog были обновлены для установки FLAG_KEEP_SCREEN_ON , чтобы анимация выполнялась до завершения, а диалоговые окна автоматически закрывались, как и предполагалось. ( Iad7d4 )
• Исправлена ​​ошибка, из-за которой Modifier.edgeSwipeToDismiss приводил к сбою при использовании с SwipeDismissableNavHost в API 36 и более поздних версиях. ( Ifc13d )
• Обновлена ​​документация и комментарии, связанные с новым параметром CurvedTextStyle warpOffset для корректного указания случая Unspecified. ( I41aa5 )

Изменения API

• Добавлены некликабельные варианты для Card , TitleCard , OutlinedCard и AppCard ( I509bb , b/406690146 )
• Удален параметр interactionSource из новых API некликабельных карточек. ( If0c7a , b/440323280 )
• Добавлен новый тип MinutesSeconds в компонент TimePicker , который отображает только столбцы минут и секунд, исключая столбец часов ( Ia9e94 , b/438004664 ).

Исправления ошибок

• Исправлено использование HorizontalPagerScaffold параметра-модификатора, чтобы HorizontalPager не терял индикатор страницы при добавлении Modifier.fillMaxSize() ( I07ae1 , b/441682601 ).
• Выровняйте направление ScrollIndicator с направлением макета содержимого по умолчанию. ( I0da0f , b/441489028 )

Версия 1.5.0-rc02

13 августа 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-rc02 . Версия 1.5.0-rc02 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка в TimePicker , из-за которой длинные интернационализированные строки для периода (AM/PM) могли нарушить макет. ( I0fa81 )

Версия 1.5.0-rc01

30 июля 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-rc01 . Версия 1.5.0-rc01 содержит следующие коммиты .

Исправления ошибок

• TimePicker теперь полностью управляется локалью пользователя, используя DateFormat.getBestDateTimePattern для определения порядка и содержимого своих элементов выбора и разделителей. Это исправляет некорректный порядок столбцов для языков CJK, устраняет проблемы с написанием справа налево в таких языках, как арабский, использует локализованные разделители и поддерживает форматы часов 0–11 и 1–12 в зависимости от локали ( I5d543 ).
• DatePicker теперь отображает месяц в числовом формате в некоторых локалях, например, CJK, чтобы избежать смешивания числовых и языковых форматов (например, 2025 | 07 | 02 вместо 2025 | 7月 | 02). Это изменение применяет эвристику, которая проверяет, используются ли в локали языковые суффиксы для обозначения года, и, если да, меняет формат месяца с текстового (MMM) на числовой (MM) для обеспечения согласованности. ( Ia93fe )
• Вертикальное пространство для заголовка в компоненте «Выбор» теперь постоянно, что предотвращает видимое смещение при выборе столбца выбора, особенно в режиме Talkback . ( I7f8b7 )
• Исправлена ​​ошибка доступности, вызванная отображением HorizontalPageIndicator и VerticalPageIndicator на весь экран. Индикаторы страниц больше не отображаются на весь экран и будут позиционироваться автоматически при использовании с HorizontalPagerScaffold или VerticalPagerScaffold . Если шаблон пейджера не используется, укажите выравнивание явно с помощью modifier = Modifier.align(Alignment.BottomCenter) для HorizontalPageIndicator и modifier =Modifier.align(Alignment.CenterEnd) для VerticalPageIndicator . ( I3a0ad )
• Направление смахивания в SwipeToReveal теперь одинаково для LayoutDirections как LTR, так и RTL. ( I6d427 )
• Восстановлено вертикальное центрирование SwipeToReveal для действий. Если hasPartiallyRevealedState = true , RevealState должен быть сброшен до RevealValue.Covered вызывающим кодом при прокрутке. ( I6473d )
• SwipeDismissableNavHost теперь корректно обрезает содержимое для API 36 и более поздних версий. ( Ib9a44 )

Версия 1.5.0-beta06

16 июля 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-beta06 . Версия 1.5.0-beta06 содержит следующие изменения .

Исправления ошибок

• Исправлена ​​анимация EdgeButton , когда LazyColumn или ScalingLazyColumn имеют reverseLayout = true . ( I46a1a )
• Исправлена ​​ошибка в ScreenScaffold , из-за которой функция Touch-to-Explore не работала в режиме Talkback, если был указан ScrollIndicator/PageIndicator . ( I6dcee )
• TransformingLazyColumn теперь позволяет выполнять пользовательскую трансформацию из TransformationSpec путем считывания значения itemHeight , предоставленного TransformationSpec в фоновом рисовщике. ( I6a599 )
• Анимированные переходы цветов для IconButton включены/выключены для соответствия IconToggleButton . ( Ife10a )
• Убрано ограничение минимального размера сечения в CircularProgressIndicator , чтобы избежать заметного скачка к минимальному размеру точки при анимации. В связи с этим изменением параметр targetProgress в drawCircularProgressIndicator теперь не используется. ( I33309 )
• В средстве выбора теперь есть семантическая роль ValuePicker , которую могут использовать программы чтения с экрана для повышения доступности. Кроме того, в средстве выбора обновлены метки щелчков, которые различаются между изменением значения в режиме «только для чтения» и выбором текущего значения в противном случае. ( I33309 )

Версия 1.5.0-beta05

2 июля 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-beta05 . Версия 1.5.0-beta05 содержит следующие изменения .

Исправления ошибок

• Обновлена ​​документация для уточнения использования Modifier.edgeSwipeToDismiss ( I78cb5 ).
• Исправлена ​​ошибка, из-за которой в ленивых списках с помощью SwipeToReveal могло отображаться несколько раскрытых элементов ( I1d4f6 ).
• Формы контейнеров в TransformingLazyColumn теперь масштабируются, чтобы избежать обрезки содержимого. ( I9221a )
• Метки TimePicker и DatePicker для часов/минут/секунд или года/месяца/дня теперь имеют семантику заголовков для программ чтения с экрана ( I77d8b )
• Убрана пауза между циклами в неопределенном CircularProgressIndicator ( Iaf0bb )
• Исправлена ​​ошибка анимации в TransformingLazyColumn при удалении элементов. ( I73034 )
• Исправлена ​​обработка элементов привязки в TransformingLazyColumn при удалении элементов. ( I841a8 )
• PickerGroup теперь анимирует элементы выбора горизонтально при включении автоцентрирования и изменении выбранного (центрированного) элемента выбора. ( Ic82c4 )

Версия 1.5.0-beta04

18 июня 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-beta04 . Версия 1.5.0-beta04 содержит следующие коммиты .

Исправления ошибок

• Исправлена ​​ошибка макета в TransformingLazyColumn , из-за которой содержимое, помещающееся на экране, теперь правильно выравнивается по верхнему краю экрана ( I80115 ).
• Исправлена ​​проблема с TransformingLazyColumn , из-за которой нижний элемент неправильно масштабировался при прокрутке списка до самого низа с помощью EdgeButton . Теперь при восстановлении макета ход прокрутки следует градиентному спуску. ( Iea375 )
• TransformingLazyColumn теперь считывает высоту элемента внутри фонового рисователя, что позволяет настраиваемым TransformationSpecs реализовывать морфинг. ( I022f0 )
• SwipeToReveal теперь правильно центрирует отображаемые действия по вертикали. ( I4419b )
• Исправлена ​​ошибка в SwipeToReveal , из-за которой функция не работала корректно при смахивании для закрытия, если на экране одновременно использовались и просмотр, и создание сообщения. ( I5dc0e )
• Исправлена ​​ошибка, из-за которой действия SwipeToReveal отображались с вертикальным смещением при прокрутке. ( I29444 )
• AlertDialog , ConfirmationDialog , OpenOnPhoneDialog и SwipeToReveal теперь округляют отступы и размеры, которые рассчитываются как процент от размера экрана. ( I76367 )
• ButtonDefaults.outlinedButtonBorder теперь обновляется в соответствии с изменениями размера включенного/выключенного состояния ( If2ddd )
• Исправлена ​​ошибка высоты EdgeButton , возникавшая на сложных экранах с Pager и ScreenScaffold . ( I946e3 )
• Исправлено состояние гонки, которое могло привести к остановке анимации плейсхолдеров. ( I53530 )
• Улучшена производительность HorizontalPageIndicator и VerticalPageIndicator за счет рисования на холсте. ( Ifae1e )
• Уточнена форма EdgeButton для сглаживания переходов между эллипсисом и кругами, составляющими контур. ( I7721e )
• Исправлена ​​ошибка в LevelIndicator , приводившая к остановке анимации из-за ненужных перекомпозиций. ( I45d08 )

Версия 1.5.0-beta03

4 июня 2025 г.

Изменения API

• OpenOnPhoneDialog теперь озвучивает только текст сообщения в TalkBack и пропускает семантику значка. OpenOnPhoneDialogDefaults обновлены: параметры iconContentDescription и contentDescription удалены из icon() . Кроме того, ConfirmationDialogDefaults теперь имеет параметры-модификаторы для компонуемых объектов SuccessIcon и FailureIcon . ( Id2ae2 )

Исправления ошибок

• Изменён порядок применения параметров SurfaceTransformation . Ранее преобразования, применяемые к компонентам Wear Material3, выполнялись следующим образом: рисование фона, преобразование контейнера, преобразование содержимого. Теперь первые два инвертируются, и между ними применяется любой переданный модификатор, поэтому на него влияют преобразования контейнера. Это исправляет такие случаи, как использование эффекта мерцания заполнителя с элементами в TLC, использующими параметр преобразования. ( I786cf )
• Добавлен RevealState.Saver для использования при восстановлении состояния SwipeToReveal при повторном создании активности или процесса. Функция rememberRevealState теперь использует этот Saver по умолчанию. ( Ie0ecb )
• Кнопки основных и дополнительных действий SwipeToReveal должны по умолчанию иметь значение ButtonDefault.Height (исправлена ​​ошибка, из-за которой они заполняли максимальную высоту для более высоких кнопок). ( Ibfba1 )
• Изменено SwipeToReveal для сброса последнего взаимодействовавшего компонента при выполнении жеста смахивания вправо. ( Ia8450 )
• SwipeToReveal был изменен для установки в состояние Revealing , когда конечная позиция смахивания находится между якорями раскрытия и раскрытия и ближе к якорю раскрытия. ( If4458 )
• Теперь содержимое ButtonGroup правильно инвертируется в макете RTL ( Ib378d )
• AnimatedText теперь поддерживает направление текста справа налево ( I4533c )
• TransformingLazyColumn теперь правильно изменяет размеры элементов при удалении нижнего элемента ( Idacab )
• TransformingLazyColumn теперь выполняет только один проход измерения, что повышает производительность за счет сокращения времени кадра. ( I501a1 )

Версия 1.5.0-beta02

• Исправлена ​​ошибка в TransformingLazyColumn , из-за которой элементы изменялись в размере при удалении нижнего элемента. ( Idacab )
• Исправлена ​​ошибка TransformingLazyColumn , из-за которой список застревал в верхней или нижней части списка. ( I49d00 )
• OpenOnPhoneDialog в TalkBack должен озвучивать изогнутый текст, а не описание содержимого значка. ( I4efe8 )
• Исправлена ​​ошибка в SwipeToReveal , из-за которой сообщалось о неправильной привязке в RevealState.currentValue , если hasPartiallyRevealedState имел значение false. ( I9c7cf )
• Кнопки отмены SwipeToReveal теперь по умолчанию имеют ButtonDefaults.Height . ( I1f6c8 )
• Производительность BasicSwipeToDismissBox была улучшена за счет отказа от использования Canvas для рисования сеток. ( I68f2c )
• Исправлена ​​ошибка доступности в Slider, из-за которой объявленный процент не соответствовал значению после обновлений ( I91146 ).
• Исправлена ​​ошибка в реализации placeholderShimmer . ( Iee39b
• Производительность TransformingLazyColumn была улучшена за счет оптимизации расчета ScrollProgress на 30%. ( I4c4cb )

Версия 1.5.0-beta01

7 мая 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-beta01 . Версия 1.5.0-beta01 содержит следующие изменения .

Выпуск Compose для Wear OS версии 1.5.0-beta01 означает, что в этом выпуске библиотека имеет полный набор функций, а API заблокирован (за исключением случаев, помеченных как экспериментальные).

Wear Compose 1.5.0-beta01 включает библиотеку Wear Compose Material3, которая поддерживает новую систему дизайна пользовательского интерфейса Material 3 Expressive. Рекомендуется перейти с Material на Material3, чтобы использовать новый визуальный дизайн в приложениях и воспользоваться следующими новыми компонентами:

• MaterialTheme для обновленных и расширенных цветовых схем, типографики и форм, которые привнесут в ваши проекты глубину и разнообразие.
• Динамическая цветовая схема, которая автоматически генерирует цветовую схему для вашего приложения в соответствии с цветами циферблата часов.
• Новые компоненты по умолчанию автоматически адаптируются к большим размерам экрана.
• Изменение формы — компоненты круглой кнопки, такие как IconButton , TextButton , IconToggleButton и TextToggleButton поддерживают вариации, которые анимируются при нажатии или выборе.
• EdgeButton — новая кнопка специальной формы, прилегающая к краю экрана.
• Scaffolds — представляем AppScaffold и ScreenScaffold для разработки структуры экрана и координации анимаций ScrollIndicator и TimeText .
• Кнопки — множество кнопок в форме стадиона поддерживаются гибкими однослотовыми контейнерами и многослотовыми вариантами для кнопок с иконками и надписями. CheckboxButton и SwitchButton предоставляются для переключателей, а RadioButton — это доступная кнопка выбора (также доступны варианты «Разделённые» для переключателей и кнопок выбора).
• ButtonGroup — реализует выразительную группу кнопок в ряду, которые меняют форму при касании.
• Варианты AlertDialog поддерживают кнопки «ОК/Отмена» или EdgeButton .
• ConfirmationDialog позволяет отображать сообщение с задержкой, поддерживая специальные анимации для успешного завершения, неудачного завершения и вариантов открытия по телефону.
• Поддерживаются варианты Pickers — TimePicker и DatePicker , а также компоненты Picker и PickerGroup для создания собственных экранов Pickers.
• ProgressIndicators — поддерживаются круговые и линейные индикаторы прогресса ( CircularProgressIndicator имеет сегментированные и неопределенные варианты).
• Карточки — доступно несколько вариантов карточек, включая TitleCard , предлагающий специальные макеты для карточек с заголовком, временем, подзаголовком или полем для содержания. TitleCard также можно использовать фоновое изображение, чтобы подчеркнуть смысл информации на карточке.
• Компоненты Pagers — HorizontalPagerScaffold , VerticalPagerScaffold и AnimatedPage координируют анимацию HorizontalPageIndicator и VerticalPagerIndicator . HorizontalPager и VerticalPager входят в библиотеку Wear Compose Foundation.
• Заполнители — рисуют каркасную форму над компонентом для ситуаций, когда временное содержимое отсутствует.
• Ползунки и степперы — как ползунки, так и степперы позволяют пользователям выбирать из диапазона значений. Ползунки более компактны и могут быть сегментированы, тогда как степпер — это полноэкранный компонент, обычно работающий в паре с StepperLevelIndicator .
• SwipeToReveal — используется для добавления дополнительных действий к компонуемому элементу при его смахивании справа налево.

Кроме того, Wear Compose Foundation 1.5.0-beta01 включает в себя следующие новые компоненты:

• TransformingLazyColumn — ленивый, вертикально прокручиваемый список, поддерживающий анимацию масштабирования и морфинга.
• Иерархические фокус-группы — используются для аннотирования компонуемых элементов в приложении, отслеживания активной части композиции и координации фокуса.
• Пейджеры — компоненты HorizontalPager и VerticalPager , созданные на основе компонентов Compose Foundation с усовершенствованиями, специфичными для Wear, для повышения производительности и соответствия рекомендациям Wear OS.

Изменения API

• Обновлен API иерархического фокуса — Modifier.hierarchicalFocus переименован в Modifier.hierarchicalFocusGroup и удален параметр обратного вызова; удалена перегрузка Modifier.hierarchicalFocusRequester с параметром FocusRequester ; создан новый CompositionLocal , LocalScreenIsActive , чтобы компоненты могли сообщать и проверять, какой экран является активным. ( I5ff7c ).
• Устаревший SwipeToReveal из Wear Compose Foundation заменен API SwipeToReveal в Wear Compose Material и Wear Compose Material3. Чтобы продолжить использование API, замените импорт SwipeToReveal из Wear Foundation на импорт Wear Compose Material/Wear Compose Material3. ( Ia147d ).
• Зависимости Wear Compose Material3 SwipeToReveal от Foundation были перенесены в пакет material3, например, RevealValue , RevealDirection , RevealActionType , RevealState и rememberRevealState . Разработчикам следует изменить импорт этих классов и функций с androidx.wear.compose.foundation на androidx.wear.compose.material3 . ( I640e6 ).
• Обновлен API Wear Compose Material3 SwipeToReveal следующим образом: добавлены параметры primaryAction , onFullSwipe , secondaryAction , undoPrimaryAction , undoSecondaryAction и hasPartiallyRevealedState в составной элемент SwipeToReveal ; удалена возможность настройки positionalThreshold и animationSpec из RevealState ; удалены lastActionType , revealThreshold и width из RevealState ; изменен конструктор RevealState для принятия RevealDirection вместо якорей; удалены функции createRevealAnchors , якори и bidirectionalAnchors ; функции SwipeToRevealScope primaryAction , secondaryAction , undoPrimaryAction и undoSecondaryAction переименованы в PrimaryActionButton , SecondaryActionButton , UndoActionButton и преобразованы в составные функции; помечен RevealActionType как внутренний. ( I885d0 ).
• Далее API SwipeToReveal обновлено следующим образом: onFullSwipe переименован в onSwipePrimaryAction ; SwipeToRevealNonAnchoredSample переименован для указания использования параметра hasPartiallyRevealedState ; удален actionButtonHeight , поскольку значение по умолчанию равно высоте кнопки по умолчанию, а большую высоту можно задать с помощью модификатора; удален SmallActionButtonHeight из SwipeToRevealDefaults ; параметр value в конструкторах RevealValue и RevealDirection сделан закрытым. ( I465ce ).

Исправления ошибок

• Исправлена ​​обработка EdgeButton в ScreenScaffold , так что после удаления элемента TransformingLazyColumn EdgeButton анимированно возвращается на место. ( I6d366 ).
• Обновлены зависимости Wear Compose от библиотек Compose до версии 1.8.0. ( I2ef3f ).
• Обновлено движение неопределенного CircularProgressIndicator , так что теперь он больше не регрессирует временно. ( Ieddb1 ).
• Исправлена ​​ошибка SwipeDismissableNavHost — фокус не переключался правильно после смахивания назад, что приводило к сбою вращательного ввода (это было для API 36+, в котором используется предиктивный возврат). ( Ieddb1 ).
• Измененная документация для Hierarchical Focus API ( Idf2ff ).
• Обновлена ​​документация для Button и Card с целью описания того, как containerPainter и disabledContainerPainter переопределяют containerColor и disabledContainerColor ( I4a453 ).
• Отменено изменение TimeText в предыдущем выпуске , которое перемещало BroadcastReceiver в рабочий поток, поскольку это вызывало проблемы для приложений, которые управляют собственными потоками во время навигации. ( I34d02 ).
• Обновлены примеры Picker для удаления ненужных вызовов remember и использования вместо этого rememberUpdatedState в Picker для запоминания последней лямбда-функции contentDescription . ( Icb5b1 ).
• Обновлены стили текста в TimePicker и DatePicker , чтобы изменение шрифта больше не приводило к усечению. ( I26194 ).
• ListHeader и ListSubHeader теперь по умолчанию выравнивают текст по центру и по началу соответственно. ( I78339 ).
• Обновлены примеры и демонстрации Foundation и Material Swipe to Reveal для анонсирования пользовательских действий по обеспечению доступности (пользовательские действия должны быть добавлены как семантика для контента, а не для самого компонуемого объекта SwipeToReveal ). ( Ie92a3 ).
• Обновлено значение MaxLines по умолчанию для содержимого EdgeButton в соответствии с его размером — теперь 1 для очень маленького, 2 для маленького и среднего и 3 для большого. ( Ie35f6 ).
• Упрощенный LocalReduceMotion позволяет регистрировать наблюдателя только один раз для повышения производительности. ( Ib1979 ).
• Минимизировано количество перерисовок в ScrollIndicator для повышения производительности. ( Ia7a67 ).
• Исправлена ​​ошибка в TransformingLazyColumn , из-за которой верхний видимый элемент в списке не масштабировался правильно, когда EdgeButton достигал своей полной высоты. ( I30580 ).

Выпущена androidx.wear.compose:compose-*:1.5.0-alpha12 . Версия 1.5.0-alpha12 содержит следующие коммиты .

Изменения API

• Улучшить реализацию по умолчанию SwipeToReveal для gestureInclusion , чтобы жесты игнорировались только в том случае, если состояние компонента — Covered. ( I7e3d6 )
• Для SwipeToReveal сделал bidirectionalGestureInclusion значением вместо функции и добавил @FloatRange к параметру edgeZoneFraction в gestureInclusion . ( Ica7c3 )

Версия 1.5.0-альфа11

12 марта 2025 г.

Выпущена androidx.wear.compose:compose-*:1.5.0-alpha11 . Версия 1.5.0-alpha11 содержит следующие коммиты .

Изменения API

• Updated PagerState , removing the Compose Foundation PagerState as the base class and adding currentPage , currentPageOffsetFraction and pageCount properties. Updated the GestureInclusion interface, renaming the method to ignoreGestureStart . ( I4ae07 )
• Add requireOffset to SwipeToDismissBoxState as the recommended way of getting an offset of SwipeToDismissBoxState . ( I21042 )
• Added CurvedModifier.semantics , initially supporting content description and traversal index ( I0b093 )
• We have added CurvedModifier.clearAndSetSemantics to provide a means by which curved semantics can be turned off. CurvedText continues to default the content description to the text, but timeTextCurvedText and timeTextSeparator do not now announce their contents. ( I4b568 )
• HorizontalPager 's default handling of swipe gestures has been renamed to PagerDefaults.gestureInclusion . The default behavior is now to only ignore swipe gestures that start on the left edge of the first page, and only then when Talkback is turned off. In other cases, the default behavior is that swipe gestures will not be ignored by the pager, so they will not be available to swipe-to-dismiss handlers. ( Iee486 )
• Added rotary overscroll for rotaryScrollable api. Overscroll and nested scroll were added to rotaryScrollable fling behavior. This change should bring on-par overscroll and nested scroll functionality between touch scroll and rotary scroll. ( I71926 )
• Added support for an edge-swipe zone to SwipeToReveal . Foundation SwipeToReveal 's default behavior is now to disallow swiping when the gesture starts from the edge. Material3 SwipeToReveal 's default behavior is now to disallow swiping when the gesture starts from the edge, when the SwipeDirection is set to single direction. ( I32ef0 )
• TLC now uses empty contentPadding by default instead of putting first and last items into center. ( I77ab7 )

Исправления ошибок

• Wear Compose libraries have been updated to the Kotlin 2.0 compiler. ( I2de79 )
• Fixed the curved LetterSpacing sample on foundation. ( Iebf7c )

Version 1.5.0-alpha10

26 февраля 2025 г.

androidx.wear.compose:compose-*:1.5.0-alpha10 is released. Version 1.5.0-alpha10 contains these commits .

Изменения API

• Make SwipeToRevealDefaults public. ( I0c34c )
• We have replaced the swipeToDismissEdgeZoneFraction parameter in HorizontalPager . Instead a new parameter, gestureInclusion has been introduced which can be used to achieve necessary swipe to dismiss behaviour. gestureInclusion takes in an instance of GestureInclusion which decides whether the subsequent scroll event should proceed or not. Allowing a gesture means that the Pager consumes it - otherwise, it will be handled elsewhere such as by a swipe-to-dismiss handler. The new default behaviour is to disallow gestures on the leftmost edge of the first page in the Pager, and hence allow swipe to dismiss in this region. All other pages will permit the Pager to consume all gestures, meaning Swipe to dismiss cannot be triggered from them. To achieve Swipe to dismiss behaviour on all pages, simply provide a custom GestureInclusion instance (see PagerDefaults.disableLeftEdgeOnFirstPage ) that ignores the current page. Another breaking change introduced here is that the Pager component is no longer full screen by default, instead add Modifier.fillMaxSize() to achieve this behaviour. ( I9d3aa )
• We have renamed createAnchors to createRevealAnchors in the swipe-to-reveal API( If5999 )
• We have removed RevealScope from the swipe-to-reveal API. ( Ie4ad5 )
• We have removed Revealing and Revealed from RevealValue in the swipe-to-reveal API. ( I8dbc5 )
• We have renamed SwipeDirection to RevealDirection in the swipe-to-reveal API. ( I7472f )
• We have changed the signature of the positionalThreshold parameter of SwipeToReveal 's rememberRevealState function. ( I29c0a )
• We have added a new overscrollEffect parameter added to ScalingLazyColumn , TransformingLazyColumn and ScreenScaffold . ( I0cee8 )
• When using PagerDefaults#snapFlingBehaviour , the pagerSnapDistance parameter has been replaced with an Int parameter maxFlingPages , which can be used to specify the max number of pages the Pager should fling. ( I8cfc0 )
• Wear Pager now has its own PagerScope instead of using Compose Foundation PagerScope . ( I9195b )
• We have added support for lineHeight on Curved text ( I1c936 )
• We have added initialAnchorItemIndex and initialAnchorItemOffset to TransformingLazyColumnState and rememberTransformingLazyColumnState to that the initial scroll position can be specified in TransformationLazyColumn . ( I0a0d5 )
• Deprecate runWithTimingDisabled in favor of runWithMeasurementDisabled , which more clearly describes the behavior - all metrics are paused. Additionally, expose the MicrobenchmarkScope superclass since redeclaring the runWithMeasurementDisabled function to open access isn't possible, since it's inline. ( I9e23b , b/389149423 , b/149979716 )
• We have added TransformingLazyColumnItemScrollProgress.Unspecified to the API to avoid boxing on TransformingLazyColumnItemScrollProgress . ( I0835d )

Исправления ошибок

• Improve Kdoc for CurvedTextStyle ( Id45e3 )
• We have made SwipeableV2 (part of the SwipeToReveal implementation) internal instead of public but restricted to library group. ( Idbb94 )

• We have implemented prefetching for TransformingLazyColumn to reduce jank ( Icca88 )

Version 1.5.0-alpha09

29 января 2025 г.

androidx.wear.compose:compose-*:1.5.0-alpha09 is released. Version 1.5.0-alpha09 contains these commits .

Изменения API

• On CurvedTextStyle , we have split letter spacing into clockwise letter spacing and counter clockwise letter spacing. This is required because clockwise letters fan out from the baseline whereas counter-clockwise letters fan in (so larger letter spacing is needed) ( I4b848 )
• The CompositionLocal LocalReduceMotion has been simplified to return a Boolean instead of a ReduceMotion object. The ReduceMotion interface has now been deprecated. Previous invocations such as LocalReduceMotion.current.enabled() can be replaced with LocalReduceMotion.current ( I4937f )
• In PagerDefaults , snapAnimationSpec has been renamed to SnapAnimationSpec . ( I20c9a )

• TransformingLazyColumn now exposes values for beforeContentPadding and afterContentPadding . ( Iccd5f )
• TransformingLazyColumn now provides the composition local LocalTransformingLazyColumnItemScope which components (such as Card s and Button s in Material3) can use to automatically morph when placed inside a TransformingLazyColumn . Callers can disable automatic morphing using the new TransformExclusion wrapper. ( I1652f )

Исправления ошибок

• We have updated min and max fling velocities for rotary on devices targeting U onwards. ( I33559 )
• We have fixed a crash that occurred if an item in TransformingLazyColumn did not contain any composables ( Idb99d )
• We have added ScrollFeedbackProvider support for rotary haptics on Android Vanilla ice cream. ( Ibc553 )
• We have applied an increased touch slop when using SwipeToReveal in order to reduce the chances of accidentally triggering a swipe when vertically scrolling. ( Ic0672 )

• We have simplified the ScrollInfoProvider for PagerState by removing the orientation parameter, which is no longer needed. The new behavior is for TimeText to remain in place for both horizontal and vertical paging. ( I71767 )
• TransformingLazyColumn was introduced in earlier releases. We are now removing Wear's LazyColumn aliases (which were forwarding to TransformingLazyColumn ) in favor of the new name TransformingLazyColumn . We have also removed TransformingLazyColumnVisibleItemInfo 's height property - please use measuredHeight instead. ( I0ea1e )
• We have changed the PagerDefaults.snapFlingBehavior snapAnimationSpec from a Tween to a Spring spec.( I10d02 , b/349781047 , b/303807950 )
• We have promoted the LocalReduceMotion CompositionLocal to stable ( Ia6f32 )

Исправления ошибок

Изменения API

• We have added support for bi-directional swiping in SwipeToReveal , for rare cases where the current screen does not support swipe to dismiss. . The default is still to swipe-to-reveal only on right-to-left swipes and it is strongly advised to respect the default behavior to avoid conflict with swipe to dismiss. ( Ifac04 )

The 1.4-beta01 release of Compose for Wear OS indicates that this release of the library is feature complete and the API is locked (except where marked as experimental). Wear Compose 1.4 includes the following new functionality:

• We have added Modifier.rotaryScrollable , a new modifier that connects rotary events with scrollable containers, allowing users to scroll via a crown or a rotating bezel on their Wear OS device. In addition, ScalingLazyColumn and Picker now support rotary input by default. Use the rotaryScrollableBehavior parameter to configure either scroll or snap behavior. For snap behavior, it is recommended to provide snap via the flingBehavior parameter as well for touch scrolling.
• SwipeDismissableNavHost now provides an entry animation for in-app transitions.
• PositionIndicator is now shown by default when a screen is first displayed.
• SelectableChip and SplitSelectableChip have been added as a variation on ToggleChip - use this with RadioButton in order to provide selectable semantics instead of toggleable semantics for accessibility
• ListHeader now supports height adjustments when contents need extra height to accommodate large font sizes.

Изменения API

• We have made the following changes to the new rotary API: renamed Modifier.rotary to Modifier.rotaryScrollable ; renamed the RotaryBehavior interface to RotaryScrollableBehavior and its function handleScrollEvent to performScroll ; renamed RotaryScrollableAdapter to RotaryScrollableLayoutInfoProvider and removed the scrollableState property. ( I0c8a6 )
• We have made additional changes to the rotary API: renamed RotaryScrollableLayoutInfoProvider to RotarySnapLayoutInfoProvider (because this provider is only needed for rotary with snap); changed the type of the snapOffset parameter in RotaryScrollableDefaults.snapBehavior snapOffset from Int to Dp. ( Iddebe )
• We have renamed the clickInteractionSource parameter on SplitSelectableChip to containerInteractionSource . ( Ia8f84 )
• We have updated the click callback parameter names for SplitSelectableChip - from onClick to onSelectionClick and from onBodyClick to onContainerClick . ( I32237 )

Исправления ошибок

• We have updated the horizontal padding for PositionIndicator to 2dp (was 5dp), in order to fix a bug where the PositionIndicator (scroll bar) overlaps scrollable content. Please note that this change is expected to break existing screenshots that include the PositionIndicator due to the change of padding. ( I57472 )
• We have improved the documentation for the new rotary API by describing the differences between low-res and hi-res rotary devices. ( I63abe )
• We have addressed an out-of-range exception in SwipeDismissableNavHost that could be triggered when interpolated alpha values were less than zero. ( Ib75a1 , b/335782510 )

In addition, ScalingLazyColumn and Picker now support rotary input by default, with new overloads that include the rotaryBehavior parameter for specifying the configuration of either scroll or snap. If the rotaryBehavior parameter is set to snap, then it is recommended to provide snap via the flingBehavior parameter as well, for touch scrolling. ( I2ef6f )
• 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 )
• We have added SelectableChip and SplitSelectableChip to make the distinction clearer between toggle controls such as Switch/Checkbox and selectable controls such as RadioButton . This replaces the previously added overloads of ToggleChip/SplitToggleChip with selectionControl parameters. ( Ia0217 )
• Updated visibility modifier of IndeterminateStrokeWidth in ProgressIndicatorDefaults to public. ( I5b5a4 )

Изменения API

• The Modifier.inspectable wrapper has been deprecated. This API will create more invalidations of your modifier than necessary, so its use is now discouraged. Developers are encouraged to implement the inspectableProperties() method on ModifierNodeElement if they would like to expose modifier properties to tooling. ( Ib3236 )

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

Новые функции

• We have added entry animation to SwipeDismissableNavHost for in-app transitions.( cfeb79a )
• PositionIndicator is now shown by default when a screen is first displayed. This change was introduced in order to help meet Wear Quality guidelines. Unfortunately, it means that screenshot tests will need to be updated on screens that include PositionIndicator , as the PositionIndicator would not previously have been displayed. ( 419cef7 )

Изменения API

• We have added a new ripple API in wear:compose-material and wear:compose-material3 libraries which replaces the deprecated rememberRipple . Also adds a temporary CompositionLocal , LocalUseFallbackRippleImplementation , to revert Material components to using the deprecated rememberRipple/RippleTheme APIs. This will be removed in the next stable release, and is only intended to be a temporary migration aid for cases where you are providing a custom RippleTheme . See developer.android.com for migration information and more background information behind this change. ( af92b21 )
• We have updated ColorScheme to be immutable, making individual color updates less efficient, but making more common usage of colors more efficient. The reasoning behind this change is that the majority of apps wouldn't have updating individual colors as a main use case. This is still possible but it will recompose more than before, in turn we significantly decrease the amount of state subscriptions through all of the material code and will impact initialization and runtime cost of more standard use cases. ( f5c48b7 )
• Wear material and Wear material3 components exposing a MutableInteractionSource in their API have been updated to now expose a nullable MutableInteractionSource that defaults to null. There are no semantic changes here: passing null means that you do not wish to hoist the MutableInteractionSource , and it will be created inside the component if needed. Changing to null allows for some components to never allocate a MutableInteractionSource , and allows for other components to only lazily create an instance when they need to, which improves performance across these components. If you are not using the MutableInteractionSource you pass to these components, it is recommended that you pass null instead. It is also recommended that you make similar changes in your own components. ( f8fa920 )
• We have updated rememberExpandableState to save expandable state. This ensures that data is stored when navigating to another screen and restored when coming back to the original screen. ( 5c80095 )

Исправления ошибок

• We have updated the ReduceMotion setting to use a lifecycle aware listener. ( 7c6b122 )
• We have updated TouchExplorationStateProvider 's Listener to be lifecycle aware ( be28b01 )
• We have removed the materialcore layer for CompactButton to improve performance ( 25db8e9 )
• We have made BasicSwipeToDismissBox more robust to NaN offsets to avoid exceptions ( b983739 )
• We have updated BasicSwipeToDismissBox to ensure alpha values are within the range 0,1

Версия 1.3.0

24 января 2024 г.

androidx.wear.compose:compose-*:1.3.0 is released. Version 1.3.0 contains these commits.

Important changes since 1.2.0

• The SwipeToDismissBoxState class, SwipeToDismissValue enumeration, and Modifier.edgeSwipeToDismiss extension function are now each part of the androidx.wear.compose.foundation package, instead of the androidx.wear.compose.material package. This updated architecture allows you to implement gesture handling independently from other design considerations. Material Design workflows, such as applying colors from a configured theme, are handled separately.
• The SwipeToRevealCard and SwipeToRevealChip classes help you implement the recommended swipe-to-reveal guidance . The SwipeToRevealSample class demonstrates how to use these components.

• Our 1.3.0-alpha02 release introduced a change that causes Chip and ToggleChip objects to grow in height to better support user-selected font scaling. This can cause some clipping to occur. To fix this issue, the large shape for MaterialTheme now uses a larger corner radius (26 dp instead of 24 dp). Chip and ToggleChip objects use this new corner radius to avoid clipping content on the corners of Chip and ToggleChip .

  • Most Chips and ToggleChips are unchanged, given their default 52 dp height. However, Chip and ToggleChip objects that contain multiple lines of primary or secondary label text, or for which the height has been overridden, could cause screenshot tests to break.

Дополнительные изменения

For a more complete set of the changes introduced in version 1.3.0, see the beta01 release notes .

Recommendations for implementation

• If your app allows users to pan around the screen's content, such as in a map-based app, turn off swipe handling by setting userSwipeEnabled to false in the SwipeDismissableNavHost composable, and include a button that allows users to go to the previous screen.
• To turn off animations for a position indicator during fade-in and position-change animations within a scrolling list, use a SnapSpec object.
• While waiting for a media app to load content for playback, show a blank Placeholder composable.
• To create a collection of expandable items on demand, consider using the experimental ExpandableStateMapping class.

Исправления ошибок

• We have updated the MaterialTheme large shape to use a 26dp rounded corner radius and this will now be used by Chip and ToggleChip . This change is needed to support height adjustments when contents need extra height to accommodate large font sizes—otherwise, the existing stadium shape clips some text content.

  

  

  This change may cause a breakage in screenshot tests. ( I2e6ae )

Исправления ошибок

• We have restored the intended swipe motion in BasicSwipeToDismissBox . This had been altered in a previous release, such that the slide part of the transition occurred while the finger was touching the screen. ( Id8e76 )

Версия 1.3.0-beta01

15 ноября 2023 г.

androidx.wear.compose:compose-*:1.3.0-beta01 is released. Version 1.3.0-beta01 contains these commits.

The 1.3-beta01 release of Compose for Wear OS indicates that this release of the library is feature complete and the API is locked (except where marked as experimental). Wear Compose 1.3 includes the following new functionality:

• SwipeToDismissBoxState , SwipeToDismissValue and Modifier.edgeSwipeToDismiss have been migrated from androidx.wear.compose.material to androidx.wear.compose.foundation , along with the underlying swipe-to-dismiss implementation in BasicSwipeToDismissBox . This allows the gesture handling for swipe-to-dismiss to be used independently of Material Design, for example from the SwipeDismissableNavHost in androidx.wear.compose.navigation . SwipeToDismissBox from androidx.wear.compose.material is still recommended to be used with Material Design, because it pulls colors from the MaterialTheme , then delegates the remaining implementation to the BasicSwipeToDismissBox .
• SwipeDismissableNavHost now supports a new userSwipeEnabled parameter so that swipe handling can be turned off for screens where it is not required.
• BasicSwipeToDismissBox has improved focus handling using HierarchicalFocusCoordinator .
• SwipeToReveal has new SwipeToRevealCard and SwipeToRevealChip composables in Material that follow the recommended UX guidance for Card and Chip . It also has undo support for the secondary action.
• DefaultTextStyle now turns off font padding to be consistent across the Android Platform.
• Chip and ToggleChip now adjust their height to accommodate content that has grown due to large fonts for accessibility
• PositionIndicator now has individual animation specs for the fade-in, fade-out and position-change animations. For performance reasons, we recommend that fade-in and position-change are turned off when used with scrollable lists.
• ExpandableStateMapping provides a new way to generate ExpandableStates when they need to be created on demand and not necessarily with a @Composable scope.
• Placeholder now allows resetting if the content is no longer in the ready state. Also, the reduce motion setting now applies to the shimmering effect and wipe-off motion on Placeholder .

Известные проблемы

• PositionIndicator is not initially shown when a screen is first displayed. We intend to make a change in an early 1.4 alpha so that it will be initially shown, but without any animation.

Изменения API

• We have renamed the Foundation level SwipeToDismissBox to BasicSwipeToDismissBox . This makes the distinction clearer between the Foundation level component and the Material level SwipeToDismissBox . The latter pulls colors from the MaterialTheme to be used in scrims and delegates the remaining implementation to the BasicSwipeToDismissBox . ( Ibecfc )
• We have marked rememberExpandableStateMapping as experimental and improved the performance of expandableItem . ( I5f6bc )
• We have replaced the SwipeToRevealAction class in the Material SwipeToReveal Card and Chip APIs with a slot-based API using SwipeToRevealPrimaryAction , SwipeToRevealSecondaryAction and SwipeToRevealUndoAction composables. Please see sample code for examples on how to use the new API. ( Ia8943 )
• We have replaced the PositionIndicator animation flags with AnimationSpec parameters. The individual animations can be disabled by passing snap as the AnimationSpec . ( I6c523 )

Исправления ошибок

• We have fixed a bug triggered by limited curved text when size is limited ( I50efe )
• We have addressed a potential NaN crash related to curvedComposable ( I970eb )
• We have reverted the removal of the position change highlight animation on PositionIndicator . ( Ieb424 )
• We have removed the material-core layer for material Chip to improve its performance. ( If2dcb )

Version 1.3.0-alpha08

18 октября 2023 г.

androidx.wear.compose:compose-*:1.3.0-alpha08 is released. Version 1.3.0-alpha08 contains these commits.

Изменения API

• We have added individual flags to PositionIndicator overloads, to control different animations: showFadeInAnimation , showFadeOutAnimation and showPositionAnimation . The previous API has been deprecated and forwards calls to the new one. For performance reasons and for UX consistency, when the PositionIndicator is used with a scrollable list, we recommend switching off showFadeInAnimation and showPositionAnimation flags. If PositionIndicator is used as a standalone indicator, for example for volume change, then we recommend having all 3 animations turned on. ( I44294 )
• We have deprecated the Material SwipeToDismissBoxState , SwipeToDismissValue and edgeSwipeToDismiss following the migration of Swipe-to-Dismiss functionality to wear.compose.foundation . Please replace with the wear.compose.foundation equivalents. ( Iee8c9 )

Исправления ошибок

• We have updated the baseline profiles for wear compose foundation, material and navigation libraries. ( Idb060 )
• We have reverted a behavioral change for PositionIndicator introduced in a previous CL, such that the PositionIndicator was animated when a screen was initially displayed. We intend to make a similar change in an early 1.4 alpha, so that the PositionIndicator is initially displayed, but without any animation. ( I41843 )
• We have addressed some performance issues in PositionIndicator . ( I1c654 , b/302399827 )
• We have optimized performance of the touch exploration state provider default implementation to rely on State<Boolean> rather than derived state. ( Ieec4d )
• We have set systemGestureExclusion rectangles for Android 13 and higher. ( Ib1f4b )

Версия 1.3.0-альфа07

4 октября 2023 г.

androidx.wear.compose:compose-*:1.3.0-alpha07 is released. Version 1.3.0-alpha07 contains these commits.

Изменения API

The previous API has been deprecated and forwards calls to the new one. For performance reasons and for UX consistency, when the PositionIndicator is used with a scrollable list, we recommend switching off showFadeInAnimation and showPositionAnimation flags. If PositionIndicator is used as a standalone indicator, for example for volume change, then we recommend having all 3 animations turned on. ( Ia2d63 )

Исправления ошибок

• We have made improvements to the swipe to reveal motion by adding a fade animation to the primary action text, and fading the secondary action/changing the icon scale on full swipe expansion. ( Ib7223 )
• It is recommended that Swipe to Reveal actions are made accessible and we have added custom accessibility actions to our Swipe to Reveal samples. ( I42224 )
• We have improved the performance of SwipeToDismissBox , including refactoring to ensure that the initial logic does not trigger a recomposition. The SwipeToDismissBox is now drawn as the full screen size. ( Ie0aa2 )
• We have fixed a bug when the PositionIndicator incorrectly disappeared. ( I2091a )
• Improved performance of PositionIndicator by optimizing recompositions. New flags to control the animations ( fadeIn , fadeOut and positionChange ) have been added subsequently (see API Changes) ( Ifac7d )

Version 1.3.0-alpha01

21 июня 2023 г.

androidx.wear.compose:compose-*:1.3.0-alpha01 is released. Version 1.3.0-alpha01 contains these commits.

Исправления ошибок

• As announced in 1.2.0-alpha07 and 1.2.0-alpha10 , we are now changing the DefaultTextStyle to turn off font padding to be consistent across the Android Platform. This will address some cases of text clipping with large font sizes and may also impact screen layouts, so that screenshot tests need to be updated. For example, we see text clipping here ( Ic6a86 )

• It is no longer present when font padding is turned off:

• We have updated wear.compose.foundation to be an API dependency of wear.compose.material ( I72004 , b/285404743 )

What's in Compose for Wear OS 1.2

The 1.2-beta01 release of Compose for Wear OS indicates that this release of the library is feature complete and the API is locked (except where marked as experimental). Wear Compose 1.2 includes the following new functionality:

• expandableItem and expandableItems are two new Foundation components that support expanding items within a ScalingLazyColumn . Use expandableItem for a single expandable item, such as Text in which the number of lines. Use expandableItems for a group of expandable items and expandableButton to simplify creating a button that collapses after the content is expanded.
• HierarchicalFocusCoordinator - this experimental composable enables marking sub-trees of the composition as focus enabled or focus disabled.
• Picker - the API now includes userScrollEnabled to control whether the picker is active for user scrolling.
• PickerGroup - a new composable for handling multiple pickers together. It handles focus between the pickers using the HierarchicalFocusCoordinator API and enables auto-centering of picker items.
• Placeholder - we have made updates to the shimmer and 'Wipe Off' animations. The wipe-off effect is now immediately applied when the content is ready.
• ScalingLazyColumn - we have migrated ScalingLazyColumn and associated classes from androidx.wear.compose.material.ScalingLazyColumn to androidx.wear.compose.foundation.lazy.ScalingLazyColumn . Please update to use the Foundation.Lazy version.
• SwipeToReveal - we have added experimental support for swipe-to-reveal as a means to access secondary actions, supplementing the existing 'long press' pattern.
• Stepper - now has an overload with an additional enableRangeSemantics parameter to facilitate disabling the default range semantics.
• Previews - we have added the following custom annotations for previewing composables on Wear screens: WearPreviewSmallRound previews the composable on a small, round device; WearPreviewLargeRound previews the composable on a large round device; WearPreviewSquare previews the composable on a square device. Also, the following and multi-preview annotations: WearPreviewFontScales previews the composables on a wear device with multiple font sizes, while WearPreviewDevices previews the composables on different wear devices.
• We have added a DefaultTextStyle to Wear Compose which defaults the PlatformTextStyle.includeFontPadding property to true (this is the current setting). This will allow us to synchronize turning off font padding by default with the Compose libraries in an early 1.3 alpha version - see 1.2.0-alpha10 for more information.

Новые функции

• We have added experimental support for disabled scaling and fading animation when reduce_motion setting is switched on. ( I58024 )

Исправления ошибок

• Improved documentation for angularWidthDp in CurvedSize.kt ( Iab75c )
• SwipeDismissableNavHost now logs a warning with potential causes of empty backstack. This is done to prevent unexpected crashes caused because of IllegalArgumentException which was thrown when the backstack was empty. ( I04a81 , b/277700155 )

Version 1.2.0-alpha10

10 мая 2023 г.

androidx.wear.compose:compose-*:1.2.0-alpha10 is released. Version 1.2.0-alpha10 contains these commits.

Новые функции

• We have added support for Swipe to Reveal, as a means to access secondary actions. This pattern supplements the 'long press' pattern, the existing way a user could reveal (different) secondary actions. ( I60862 )

Изменения API

• We have added RevealScope to action composables in SwipeToReveal , which gives access to the offset at which additional actions are revealed. ( I3fd56 )

Исправления ошибок

• Fixed an issue with ScalingLazyColumn being stuck on Wear API 33 after fling ( Ic4599 )
• We have made some performance improvements to PositionIndicator for jank reduction. ( I35e92 )
• We have fixed a bug in Chip and CompactChip where the semantic role was no longer being set to Role.Button . ( I93f91 , b/277326264 )

Известные проблемы

• We have identified a bug in Android Studio which causes failure in rendering preview when annotated with @WearPreviewDevices and @WearPreviewFontScales - a fix is planned for release soon. Please note that the other wear preview annotations work as intended in Android Studio Giraffe 2022.3.1 and beyond.

• In version 1.2.0-alpha07 we added DefaultTextStyle to Wear Compose, maintaining the existing PlatformTextStyle.includeFontPadding value as true - for background, see Fix font padding in Compose . We will be changing the DefaultTextStyle to turn off font padding in an early 1.3 alpha version, to be consistent across the Android Platform. This will address some cases of text clipping with large font sizes and may also impact screen layouts, so that screenshot tests need updating. For example, with large font sizes we see text clipping here:

• It is no longer present when font padding is turned off:

The new setting can be adopted now by overriding the typography in your theme - see example code .

5 апреля 2023 г.

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

Изменения API

• We have renamed ExpandableItemsState to ExpandableState . ( If85ea )
• We have added expandableButton to simplify creating a button that collapses when the content is expanded and also updated the expandables examples. ( Iae309 )

Исправления ошибок

• Improved expandable samples to show more possibilities. Modified animation of expandableItem to keep its content centered through the animation. ( I2f637 )
• Updated ToggleControls to avoid extra recompositions when manually animating the colors using State. ( I5d319 )

Version 1.2.0-alpha07

22 марта 2023 г.

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

Изменения API

• We have moved the Expandable Item components (added in 1.2.0-alpha06) from material to foundation, since they had no meaningful reference to the MaterialTheme . ( Ib0525 )

Исправления ошибок

• We have fixed a crash that occurred in a screen using PickerGroup , by ensuring that PickerGroup handles focus correctly when no Picker has the focus. Also added support for RSB scrolling in our Picker demos. ( If8c19 )
• We have improved the dialog transitions - the intro transition is now smoother to match the outro transition. ( Ib5af9 )
• We have added a DefaultTextStyle to Wear Compose which defaults the PlatformTextStyle.includeFontPadding property to true (this is the current setting). This will allows us to synchronize turning off font padding by default with the Compose libraries in the future - see ( Fix font padding in Compose ) for background. ( I2aee8 )
• Reverted an UpsideDownCake preview dependency via activity-compose that blocked publishing apps to the Google Play Store. ( I6443d )

Version 1.2.0-alpha06

8 марта 2023 г.

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

Изменения API

• Add CurvedBox component, which places components on top of each other in the curved world. ( I29200 )
• Added Expandable Item(s) - two new components to support either a group of expandable items in a ScalingLazyColumn , or an expandable single item, such as Text in which the number of lines expands. ( I95dd5 )
• We have added the following custom annotations for previewing composables on Wear screens: WearPreviewSmallRound previews the composable on a small, round device; WearPreviewLargeRound previews the composable on a large round device; WearPreviewSquare previews the composable on a square device. Also, the following and multi-preview annotations: WearPreviewFontScales previews the composables on a wear device with multiple font sizes, while WearPreviewDevices previews the composables on different wear devices. To use these previews, you must be using the latest Android Studio (Giraffe Canary 6) or beyond. Please note that if these annotations do not suit your purpose, Preview can still be used and supports further customisations via parameters. ( I397ff )
• We have marked HierarchicalFocusCoordinator as experimental while it is considered as a candidate to be moved into core compose libraries, given its wide applicability. ( I3a768 )

Исправления ошибок

• Fixed a bug on HierarchicalFocusCoordinator , when the lambda passed in for the focusEnabled parameter is changed, we now correctly use the new one. ( Icb353 )
• We have updated the default disabled content color to Background when using primary colors as the background in Button , CompactButton , Chip , CompactChip and ToggleButton . This improves the contrast for accessibility. ( I527cc )

Version 1.2.0-alpha05

22 февраля 2023 г.

androidx.wear.compose:compose-*:1.2.0-alpha05 is released. Version 1.2.0-alpha05 contains these commits.

Изменения API

Version 1.2.0-alpha04

8 февраля 2023 г.

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

Новые функции

• PickerGroup for handling multiple pickers together using the focus API. It handles the focus between the different pickers, enables auto-centering of the pickers based on parameters and allows developers to change the focus between different pickers while handling the events from the group. In talkback mode, the PickerGroup handles the talkback focus by moving the focus to the selected Picker from the group. ( I60840 )

Изменения API

• We have added an overload to Stepper with an additional enableRangeSemantics parameter in order to facilitate disabling the default range semantics ( Ia61d4 )

Исправления ошибок

• Allow ScalingLazyColumn to be nested within a horizontally scrolling page ( Iec3f8 , b/266555016 )
• Improvement of Stepper kdocs and StepperTest tests clean-up. ( Ic118e )
• Updated androidx.navigation dependency to version 2.5.3 ( If58ed )

Version 1.2.0-alpha03

25 января 2023 г.

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

Изменения API

• We have migrated ScalingLazyColumn (and associated classes) from androidx.wear.compose.material.ScalingLazyColumn to andrdoidx.wear.compose.foundation.lazy.ScalingLazyColumn (see this example for migration). This new location more closely matches that of compose.foundation.lazy.LazyColumn and is more natural as it is not an opinionated Material component. The change is happening now in preparation for a new Material3 library, which we will be working on in parallel with the existing Material library. ( I060e7 )

The following changes are part of the ScalingLazyColumn migration from Material to Foundation.Lazy :

• PositionIndicator apis targeting Material ScalingLazyColumn have been deprecated - please update to Foundation.Lazy ScalingLazyColumn . Additionally anchorType field was added to ScalingLazyListLayoutInfo . ( I29d95 )
• ScalingLazyColumn has been marked as deprecated in the Wear Compose Material package ( I16d34 )
• We have updated the ScrollAway modifier to use ScalingLazyListState from Wear Compose Foundation.Lazy and deprecated the overload that took ScalingLazyListState from Wear Compose Material. ( Ifc42c )
• We have updated the Dialog APIs to use ScalingLazyListState from Foundation.Lazy and deprecated the overloads that used Material ScalingLazyListState ( Ic8960 )
• We have updated the Picker APIs to use ScalingParams from Foundation.Lazy and deprecated the overloads that used Material ScalingParams . ( Idc3d8 )

Исправления ошибок

• We have fixed a bug that caused unnecessary recompositions in ScalingLazyListState.centerItemIndex by ensuring that it only pushes updates when the value actually changes ( Ia9f38 )
• We have improved the performance of SwipeToDismissBox ( I3933b )
• Added benchmark tests for ScalingLazyColumn in Wear Compose Foundation ( Ie00f9 )
• We have updated some internal ScalingLazyColumn classes methods in Material to use their equivalents from Foundation.Lazy ( I38aab )
• We have fixed some issues in Picker tests and add more tests for checking scroll with offset ( I6ac34 )
• We migrated the ScalingLazyColumn Integration Demos to depend on Foundation.Lazy instead of Material ScalingLazyColumn ( Ic6caa )
• We have added optional fromDate/toDate parameters to our DatePicker demo ( I961cd )

Version 1.2.0-alpha02

11 января 2023 г.

androidx.wear.compose:compose-*:1.2.0-alpha02 is released. Version 1.2.0-alpha02 contains these commits.

Изменения API

• Android Compose UI tests will now run layout passes for each frame when executing frames to get to idle (eg via waitForIdle ). This may affect tests that assert on individual frames of layout animations. ( I8ea08 , b/222093277 )
• The parameter minLines is added to Wear Text for consistent behaviour with BasicText ( I24874 )
• CompactChipTapTargetPadding has been made public so that it appears in the documentation ( If1e70 , b/234119038 )

Исправления ошибок

• Disable multiplatform builds for wear.compose packages ( Iad3d7 )
• Fix kdocs for scrollToOption ( I6f9a0 )
• PlaceholderState.rememberPlaceholderState() updated to use rememberUpdatedState to that the state will update if the onContentReady lambda. ( I02635 , b/260343754 )
• We have fixed a text jittering issue seen in the Picker component by leveraging the new compositing strategy added to Modifier.graphicsLayer . ( I99302 )
• We have fixed a bug that caused flickering in our DatePicker demo ( I660bd )
• We have improved the accessibility for the 12-hour time and date picker demos ( I05e12 )
• We have updated our time and date picker demos so that the pickers are not affected by RSB changes when unselected ( I4aecb )

Version 1.2.0-alpha01

7 декабря 2022 г.

androidx.wear.compose:compose-*:1.2.0-alpha01 is released. Version 1.2.0-alpha01 contains these commits.

Новые функции

• We've updated the experimental Placeholder functionality so that the “Wipe Off” effect is immediately applied when the content is ready rather than waiting for the next animation loop to start. We have also made some updates to the shimmer and wipe off animations. ( I5a7f4 )

Изменения API

• We have added a HierarchicalFocusCoordinator composable to enable marking sub-trees of the composition as focus enabled or focus disabled.( I827cb )
• We have added a new property to override the semantic role for ToggleButton .( I67132 )
• We have updated TimeTextDefaults.TimeFormat12Hours to remove AM/PM in TimeText . This will change the default value of timeSource parameters in TimeText API. ( I1eb7f )
• We have extended the Picker API to improve accessibility for screens with multi-picker. There is a new property userScrollEnabled to control whether the picker is active for user scrolling. ( I3c3aa )

Исправления ошибок

• We have changed the default border width for an OutlinedButton/OutlinedCompactButton from 2.dp to 1.dp to match final UX specs. ( Icf84d )
• In order to reduce the effect of the first item added to an empty ScalingLazyColumn appearing to scroll into place we have added an estimated autoCentering topPadding when the contents are empty. This change calculates the amount of top padding needed by assuming an initial item of height 0.dp. For ScalingLazyListAnchorType.ItemStart this will calculate the correct top padding, for ScalingLazyListAnchorType.ItemCenter this calculation will be incorrect as the height of the items is needed to correctly size the contents resulting in a small scroll into place effect based on the items real height.( I239a4 )
• We have updated the background scrim applied to the SwipeToDismiss animation to match the Wear platform. ( I9003e )
• We have fixed PositionIndicator handling of LazyListState and ScalingLazyListState for list items of size 0 to avoid divide by zero errors.( Ic28dd )

Исправления ошибок

• We have added baseline profile rules for Placeholders , ScrollAway , RadioButton , Switch , Checkbox , OutlinedButton , OutlinedCompactButton , OutlinedChip and OutlinedCompactChip . ( I8249c )
• We have fixed a bug in Modifier.scrollAway so that if the specified itemIndex is invalid (for example, if that item index is out of range), then the TimeText will now still be displayed. ( I2137a )
• We have updated the SwipeToDismissBox animation to match the platform implementation. After the initial squeeze animation, the screen now slides off to the right once the dismissal has been triggered. ( I41d34 )
• As an optimization, we have updated Modifier.scrollAway to only read the scrollState inside the measure block to avoid recomposing the modifier after each remeasure. ( I4c6f1 )
• We have added documentation and a sample to placeholders to show the correct ordering for Modifier.placeholder and Modifier.placeholderShimmer when applied to the same composable. ( Ie96f4 , b/256583229 )
• We have changed the default border width for an OutlinedCompactChip/OutlinedChip from 2.dp to 1.dp to match final UX specs. ( Ib3d8e )
• We have fixed a bug in rememberPickerState where updated inputs were not saved, so that composables were not updated after changes to the inputs. ( I49ff6 , b/255323197 )
• We have made some UI updates to the placeholders, 1) change the shimmer gradient to 1.5x the screen size, 2) add easing (cubic bezier) of the shimmer progression and 3) speed up the wipe-off animation (250ms). ( Id29c1 )
• We have corrected a UI bug in the placeholder wipeOff effect where Chip and Card backgrounds were wiping off slightly early due to not taking the component's position on screen into account. ( I2c7cb )
• We have updated the placeholder background drawing to merge colors rather than layer them where possible to reduce the risk of alpha blending of the different cropped layers from allowing underlying colors to bleed through at the placeholder background edges. ( I2ea26 )
• We have corrected the calculation of ScalingLazyListState.centerItemIndex/centerItemOffset so that if two items sit either side of the viewport center line the one that is closest will be considered as the centerItem . ( I30709 , b/254257769 )
• We have corrected a bug in the ScalingLazyListState.layoutInfo.visibleItemsInfo which was reporting incorrect offsets during ScalingLazyColumn initialization. Now an empty list will be returned until all list items are visible and have the correct offsets. Check for ScalingLazyListState.layoutInfo.visibleItemsInfo.isNotEmpty() will confirm that the ScalingLazyColumn initialization is complete and items are visible. ( I3a3b8 )

Version 1.1.0-beta01

24 октября 2022 г.

androidx.wear.compose:compose-foundation:1.1.0-beta01 , androidx.wear.compose:compose-material:1.1.0-beta01 , and androidx.wear.compose:compose-navigation:1.1.0-beta01 are released. Version 1.1.0-beta01 contains these commits.

What's in Compose for Wear OS 1.1

The 1.1.0-beta01 of Compose for Wear OS indicated that this release of the library is feature complete and the API locked.

• Wear Compose 1.1 release includes the following new functionality:
  • Picker - Accessibility improvements to Picker so that multi-picker screens are navigable with screen readers and the content description is accessible
  • Picker contentDescription parameter is now used only for the selected Picker option and takes a nullable String (in the previous commit, it was necessary to pass a mapping from option to the content description, but only the selected option was used).
  • Picker items are now always center-aligned, fixing a bug when setting gradientRatio to zero had the side-effect of changing the alignment.
  • Chip/ToggleChip - We have updated the default gradients for Chip/ToggleChip to bring them in line with the latest UX spec. ChipDefaults.gradientBackgroundChipColors has been updated to start from 50% of primary rather than 32.5%.
  • Chip/ToggleChip - Added overloads for modifying Chip shapes
  • Chip/Button/ToggleButton - Added a new outlined style for Chips and Buttons and new OutlinedChip and OutlinedButton composables that provide a transparent Chip/Button with a thin border.
  • Card - Updated the default gradients for Cards to bring them in line with the latest UX spec. CardDefaults.cardBackgroundPainter has been updated to start from 30% of primary and end at 20% of onSurfaceVariant (was previously 20% to 10% onSurfaceVariant ). ToggleChip.toggleChipColors changes from a linear gradient of 75% surface to 32.5% primary to 0% surface to 50% primary.
  • Button/ToggleButton - Added properties for modifying button shapes.
  • Theme - Updated a number of the default colors in the MaterialTheme in order to improve accessibility as the original colors did not have sufficient contrast resulting in difficulties for users to differentiate chip/card/button backgrounds from the theme background color.
  • InlineSlider/Stepper - Button roles added so that Talkback can recognise them as buttons.
  • Scaffold - PositionIndicator now is positioned and sized so that it only takes the space needed. This is useful, for example, if semantic information is added to it, talkback now gets the correct bounds of the PositionIndicator on screen.
  • CurvedText/TimeText - Added Modifier.scrollAway , which scrolls an item vertically in/out of view, based on scroll state (with overloads to work with Column , LazyColumn and ScalingLazyColumn ). ScrollAway is typically used to scroll a TimeText out of view as the user starts to scroll a list of items upwards.
  • CurvedText/TimeText - Added support for fontFamily , fontStyle and fontSynthesis in CurvedTextStyle , usable on curvedText and basicCurvedText
  • CurvedText/TimeText - Added fontWeight to the constructor and copy method on CurvedTextStyle
  • ToggleControls - Added animated Checkbox , Switch and RadioButton toggle controls for use with ToggleChip and SplitToggleChip . These can be used instead of the static icons provided by ToggleChipDefaults ( switchIcon , checkboxIcon and radioIcon ).
  • Placeholder - Added experimental placeholder support. This has three distinct visual effects designed to work together.
  • Firstly a placeholder background brush effect used in containers such as Chip and Cards to draw over the normal background when waiting for content to load.
  • Secondly a modifier ( Modifier.placeholder() ) to draw a stadium shaped placeholder widget over the top of content that is being loaded.
  • Thirdly a modifier gradient/shimmer effect ( Modifier.placeholderShimmer() ) that is drawn over the top of the other effects to indicate to users that we are waiting for data to load.
    • All of these effects are designed to be coordinated and shimmer and wipe-off in an orchestrated fashion.
• Core Compose dependencies updated from 1.2 to 1.3

Изменения API

• Font parameters ( fontFamily , fontWeight , fontStyle & fontSynthesis ) can now be specified directly as parameters of curvedText ( Idc422 )

Исправления ошибок

• curveText and basicCurvedText will now work properly with talkback (the have a properly sized and placed (but empty) compose-ui node associated with them, using the text as content description) ( I7af7c , b/210721259 )
• Bug fix to the Picker when PickerState.repeatedItems = false to add an explicit setting of autoCentering params on the Pickers internal ScalingLazyColumn to ensure that it is possible to scroll the zero'th option to the center of the view. ( I8a4d7 )

Version 1.1.0-alpha07

5 октября 2022 г.

androidx.wear.compose:compose-foundation:1.1.0-alpha07 , androidx.wear.compose:compose-material:1.1.0-alpha07 , and androidx.wear.compose:compose-navigation:1.1.0-alpha07 are released. Version 1.1.0-alpha07 contains these commits.

• Updated Modifier.scrollAway 's offset parameter to Dp for consistency with Modifier.offset (previously it was in pixels). Also, refactored as a LayoutModifier for efficiency. ( I9f94b )
• As part of the new toggle controls API, we have renamed RadioButton's circleColor to ringColor . ( I28fa9 )
• We have added animated Checkbox , Switch and RadioButton toggle controls for use with ToggleChip and SplitToggleChip . These can be used instead of the static icons provided by ToggleChipDefaults ( switchIcon , checkboxIcon and radioIcon ). ( I8a8c4 )

Version 1.1.0-alpha06

21 сентября 2022 г.

androidx.wear.compose:compose-foundation:1.1.0-alpha06 , androidx.wear.compose:compose-material:1.1.0-alpha06 , and androidx.wear.compose:compose-navigation:1.1.0-alpha06 are released. Version 1.1.0-alpha06 contains these commits.

Исправления ошибок

• Button roles were added to InlineSlider and Stepper so that Talkback can recognise them as buttons. ( Icb46c , b/244260275 )
• We have corrected the z-order of position and page indicators in the Scaffold. The indicators will now sit on top of the vignette and so will not be obscured by the vignette if it is present. ( Ib988f , b/244207528 )

Version 1.1.0-alpha04

24 августа 2022 г.

androidx.wear.compose:compose-foundation:1.1.0-alpha04 , androidx.wear.compose:compose-material:1.1.0-alpha04 , and androidx.wear.compose:compose-navigation:1.1.0-alpha04 are released. Version 1.1.0-alpha04 contains these commits.

Изменения API

• We have updated a number of the default colors in the MaterialTheme in order to improve accessibility as the original colors did not have sufficient contrast resulting in difficulties for users to differentiate chip/card/button backgrounds from the theme background color. The updated colors are surface(0xFF202124->0xFF303133), onPrimary(0xFF202124->0xFF303133), onSecondary(0xFF202124->0xFF303133), primaryVariant(0xFF669DF6->0xFF8AB4F8) and onError(0xFF202124->0xFF000000). The changes in colors though relatively subtle may impact existing screenshot tests. ( 81ab09 )

Исправления ошибок

• Fix a logic bug in ScalingLazyColumn that could result in lists with a small (typically exactly 2) number of list items not completing initialization and as a result being transparent. ( 504347 )

Version 1.1.0-alpha03

10 августа 2022 г.

androidx.wear.compose:compose-foundation:1.1.0-alpha03 , androidx.wear.compose:compose-material:1.1.0-alpha03 , and androidx.wear.compose:compose-navigation:1.1.0-alpha03 are released. Version 1.1.0-alpha03 contains these commits.

Новые функции

• We have added a new outlined style for Chips and Buttons and new OutlinedChip and OutlinedButton composables that provide a transparent Chip/Button with a thin border. ( Id5972 )

Изменения API

• Added overloads for modifying button shapes ( Icccde )

Исправления ошибок

• We have corrected the size of the toggle control area of the ToggleChip as it was not matching its UX spec. The UX Spec calls for a 4.dp spacer between the label and a 24x24.dp toggle control icon area giving a total 28.dp width. However the implementation is incorrectly giving 36x24.dp toggle control area. This results in taking away 8.dp of usable text label area. NOTE: This bug fix gives additional space for the text label and as result can (positively) impact the text layout for overflowing text. If you have screenshot tests including ToggleChips they may need to be updated. ( I514c8 , b/240548670 )

Version 1.1.0-alpha02

Новые функции

• We have switched Compose for Wear OS dependencies on core Compose libraries from 1.2.0 to 1.3.0-alpha0X

Изменения API

• Added overloads for modifying chip shapes ( I02e87 )

Исправления ошибок

• We have animated the visibility of the vignette when showing/hiding Dialog, to be consistent with the existing scaling animation. ( Ida33e )
• We have fixed a bug where a divide-by-zero could occur with some fling behavior when scrolling. ( I86cb6 )
• Fixed a bug in the ChipDefaults.childChipColor() to ensure that the disabled background color is fully transparent. ( I2b3c3 , b/238057342 )

Изменения API

• Picker's contentDescription parameter is now used only for the selected Picker option and takes a nullable String (previously, it was necessary to pass a mapping from option to the content description, but only the selected option was used). ( Ife6a7 )
• We have made accessibility improvements to Picker so that multi-picker screens are navigable with screen readers and the content description is accessible ( I64edb )

Исправления ошибок

• We have updated the baseline profile rules packaged with the Wear Compose library ( I9c694 )
• We have corrected the direction of the gradient for Chips in right to left mode. Was top left->bottom right, is now top right->bottom left. ( Ic2e77 )
• We have updated the default gradients for Chip/ToggleChip/Card to bring them in line with latest UX spec. ChipDefaults.gradientBackgroundChipColors has been updated to start from 50% of primary rather than 32.5%. CardDefaults.cardBackgroundPainter has been updated to start from 30% of primary and end at 20% of onSurfaceVariant (was previously 20% to 10% onSurfaceVariant ). ToggleChip.toggleChipColors changes from a linear gradient of 75% surface to 32.5% primary to 0% surface to 50% primary. ( I43bbd )
• We have added a background color ( MaterialTheme.color.surface ) behind Chip/ToggleChips that have gradient backgrounds in order to ensure that they are properly visible in the unlikely event that a light color is used behind them. ( Ibe1a4 , b/235937657 )
• Picker items are now always center-aligned, fixing a bug when setting gradientRatio to zero had the side-effect of changing the alignment. ( I712b8 )

Major features of 1.0.0

• This is the first stable release of Compose for Wear OS ( read more ).
• Compose for Wear OS builds upon the core Compose libraries providing additional wearable-specific components and, where appropriate, alternate implementations of core Compose components tailored to wearable devices.
• For a list of the key components in Wear Compose see the release notes for ( Compose for Wear OS Beta01 ).

Исправления ошибок

• We have animated the visibility of the vignette when showing/hiding Dialog, to be consistent with the existing scaling animation. ( Ida33e )
• We have fixed a bug where a divide-by-zero could occur with some fling behavior when scrolling. ( I86cb6 )
• Fixed a bug in the ChipDefaults.childChipColor() to ensure that the disabled background color is fully transparent. ( I2b3c3 , b/238057342 )

Version 1.0.0-rc02

22 июня 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-rc02 , androidx.wear.compose:compose-material:1.0.0-rc02 , and androidx.wear.compose:compose-navigation:1.0.0-rc02 are released. Version 1.0.0-rc02 contains these commits.

Исправления ошибок

• We have corrected the direction of the gradient for Cards in right to left (RTL) mode. It was top left->bottom right, and it is now top right->bottom left. ( Ic2e77 )
• We have updated the default gradients for Chip/ToggleChip/Card to bring them in line with the latest UX spec. ChipDefaults.gradientBackgroundChipColors has been updated to start from 50% of primary rather than 32.5%. CardDefaults.cardBackgroundPainter has been updated to start from 30% of primary and end at 20% of onSurfaceVariant (was previously 20% to 10% onSurfaceVariant). ToggleChip.toggleChipColors changes from a linear gradient of 75% surface to 32.5% primary to 0% surface to 50% primary. ( I43bbd )
• We have added a background color ( MaterialTheme.color.surface ) behind Chip/ToggleChips that have gradient backgrounds in order to ensure that they are properly visible in the unlikely event that a light color is used behind them. ( Ibe1a4 , b/235937657 )
• We have updated the baseline profile rules packaged with the Wear Compose library ( I9c694 )

Version 1.0.0-rc01

15 июня 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-rc01 , androidx.wear.compose:compose-material:1.0.0-rc01 , and androidx.wear.compose:compose-navigation:1.0.0-rc01 are released. Version 1.0.0-rc01 contains these commits.

Изменения API

• Interfaces in compose libraries are now built using jdk8 default interface methods ( I5bcf1 )

Исправления ошибок

• We have removed the explicit call to fillMaxWidth() on list header as it is not needed and can result in problems if a ScalinglazyColumn has a mixture of ListHeader() and Chip() components as the width will tend to grow/shrink as ListHeader items are scrolled in/out of view. ( I37144 , b/235074035 )
• We have fixed a bug in the ScalingLazyColumn that could result in the list items not drawing correctly until scrolled if the 0th list item was large enough (including padding) ( Ic6159 , b/234328517 )
• We have made a small adjustment in the ScalingLazyColumn easing as items reach the edge of the screen to match UX spec updates. Old values CubicBezierEasing(0.25f, 0.00f, 0.75f, 1.00f) -> new values CubicBezierEasing(0.3f, 0f, 0.7f, 1f) . To keep the old behavior you can override the scalingParams of ScalingLazyColumn ( Ie375c )
• We have added padding to the CompactChip in order to ensure that its tap target size is at least 48.dp high to meet the Material accessibility guidelines. This might impact any layouts you have using CompactChips as they will be taking up additional space. ( I3d57c )

Version 1.0.0-beta03

1 июня 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-beta03 , androidx.wear.compose:compose-material:1.0.0-beta03 , and androidx.wear.compose:compose-navigation:1.0.0-beta03 are released. Version 1.0.0-beta03 contains these commits.

Новые функции

• We have made ScalingLazyColumn work in Compose @Preview mode. ( I3b3b6 , b/232947354 )

Изменения API

• We have changed the default value for the ScalingLazyColumn.horizontalAlignment property from Start to CenterHorizontally to ensure that when list items do not fill the entire width of the column they will be aligned for maximum visibility. To switch back to the previous behavior set horizontalAlignment = Alignment.Start .( I9ed4b )

Известные проблемы

• CompactChip's tap/touch height is smaller than Material accessibility guidelines. This will be corrected in the next release (15th June) . If you are using CompactChip this will affect your layouts as CompactChips will now have additional padding above and below. Please adjust and test your layouts or see the bug comments for a workaround to use the existing behavior. ( b/234332135 )

Исправления ошибок

• New demo to animate adding or removing a start text on a TimeText . ( I16d75 )
• Add tests for HorizontalPageIndicator.PagesState ( I64ed0 )
• Updating TimeText closer to UX specs ( Ib7ea1 )

Версия 1.0.0-beta02

18 мая 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-beta02 , androidx.wear.compose:compose-material:1.0.0-beta02 , and androidx.wear.compose:compose-navigation:1.0.0-beta02 are released. Version 1.0.0-beta02 contains these commits.

Новые функции

• Picker now always responds to scroll events even when in read-only mode. This avoids the need for users to first select a Picker by tapping, before they can scroll. In read-only mode, options other than that currently selected are obscured by a shim in gradientColor . ( I72925 )
• We have changed the UX behavior of Chip/ToggleChip/CompactChip/SplitToggleChip to stop them from doing fillMaxWidth by default. Instead they will grow to fit their contents. To keep the previous behavior simply add modifier = Modifier.fillMaxWidth() ( I60a2c , b/232206371 )

Исправления ошибок

• CurvedTextStyle constructor taking a TextStyle now also respects the fontWeight (This may be added to the constructor and copy methods in future revisions of the API) ( Ieebb9 )
• Edge swiping improvements. When Modifier.edgeSwipeToDismiss is used and a swipe to the left is triggered from the edge area, it no longer triggers swipe-to-dismiss when swipe direction changes to the right. Previously, it was possible to trigger swipe-to-dismiss by swiping to the left and then swiping to the right.( I916ea )
• HorizontalPageIndicator now shows up to 6 pages on the screen. If there are more than 6 pages in total, it shows a half-size indicator on the left or right, with a smooth transition between pages.( I2ac29 )
• Improved default snap behavior on ScalingLazyColumn and Picker ( I49539 )
• Edge swiping improvements. When Modifier.edgeSwipeToDismiss is used, swipe-to-dismiss only triggers when first touch lands on the edge and swiped to the right, Previously it was possible to trigger swipe-to-dismiss by swiping from any part of the screen if a scroll reaches the start.( I8ca2a )

Version 1.0.0-beta01

11 мая 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-beta01 , androidx.wear.compose:compose-material:1.0.0-beta01 , and androidx.wear.compose:compose-navigation:1.0.0-beta01 are released. Version 1.0.0-beta01 contains these commits.

What's in Compose for Wear OS 1.0

The 1.0.0-beta01 of Compose for Wear OS marks an important milestone as the library is feature complete and the API locked.

Wear Compose Material components in the 1.0 release include:

• Material Theme - used as a replacement for the Compose for Mobile MaterialTheme , provides the colors, shapes and typography for building components on Wearables that implement the Wear Material Design UX guidelines out of the box.
• Button , CompactButton and ToggleButton - Button offers a single slot to take an icon, image or short text (3 characters max). Circular in shape with recommended sizes for default, large or small buttons. CompactButton offers a single slot to take any content (icon, image or text) and is circular in shape with background size extra small. CompactButton has optional transparent padding around the background that increases the clickable area. ToggleButton is a button that offers a single slot to take any content (short text, icon or image) and has on/off (checked/unchecked) states with coloring and different icons to show whether checked or not
• Cards - used to display information about applications such as notifications. Flexible design for different use cases with AppCard and TitleCard giving different layouts and support for images as either card contents or backgrounds.
• Chips - stadium shaped components similar to buttons, but with a larger area and multiple slots to allow for labels, secondary labels and icons. In different sizes and with support for images as backgrounds.
• ToggleChips and SplitToggleChips - a Chip with a checked/unchecked state and the addition of a ToggleControl slot to show an icon such as a switch or radio button to show the checked state of the component. In addition, the SplitToggleChip has two tappable areas, one clickable and one toggleable.
• CircularProgressIndicator - Wear Material progress indicator with two variations. The first expresses the proportion of completion of an ongoing task and supports a gap in the circular track between start and end angles. The second indicates indeterminate progress for an unspecified wait time.
• curvedText - forms part of the DSL for describing CurvedLayouts , along with curvedRow and curvedColumn , to lay out components around circular devices. See Wear Component Foundation below for more details on CurvedLayout and CurvedModifier (this plays a similar role to Modifiers in the non curved world and allows for configuration of various aspects of layout, padding, gradients, etc).
• Dialog, Alert and Confirmation - Dialog displays a full-screen dialog, layered over any other content, and supports swipe-to-dismiss. It takes a single slot which is expected to be opinionated Wear Material dialog content such as Alert or Confirmation. Alert is opinionated dialog content with slots for icon, title and message. It has overloads for either two negative and positive buttons shown side-by-side or a slot for one or more vertically stacked chips. Confirmation is opinionated dialog content that displays a message for a given duration. It has a slot for an icon or image (that could be animated).
• HorizontalPageIndicator - shows horizontal page position in a fashion appropriate to the Wearable form factor. Designed to take the full screen and show a curved indicator on round devices. Can be used with the Accompanist page viewer.
• Icon - A Wear implementation of Icon which takes color and alpha from the Wear Material Theme. For a clickable icon, see Button or Chip.
• Picker - displays a scrollable list of items from which to pick. By default, items will be repeated 'infinitely' in both directions. Can be displayed in read-only mode to hide unselected options.
• PositionIndicator - shows scroll position or other positional indication in a fashion appropriate to the Wearable form factor. Designed to take the full screen and shows a curved indicator on round devices.
• Scaffold - implements the basic Wear Material Design visual layout structure. This component provides an API to put together several Wear Material components (such as TimeText , PositionIndicator and Vignette ) constructing the screen, ensuring proper layout strategy for them and collecting necessary data so these components will work together correctly.
• ScalingLazyColumn - a scrolling scaling/fisheye list component that forms a key part of the Wear Material Design language. Provides scaling and transparency effects to the content items. ScalingLazyColumn is designed to be able to handle potentially large numbers of content items, which are only materialized and composed when needed.
• Slider - allows users to make a selection from a range of values. The range of selections is shown as a bar, which can optionally be displayed with separators.
• Stepper - a full-screen component that allows users to make a selection from a range of values, using increase/decrease buttons at the top and bottom of the screen, with a slot in the middle for Text or a Chip.
• SwipeToDismissBox - handles the swipe-to-dismiss gesture. It takes a single slot for the background (only displayed during the swipe gesture) and the foreground content. Can optionally be combined with the androidx navigation library by using SwipeDismissableNavHost (see Wear Compose Navigation library below).
• Text - A Wear implementation of the Compose Material Text component, taking color and alpha from the Wear Material Theme
• TimeText - a component for showing Time and application status at the top of the screen. Adjusts to screen shape by using curved text on round screens.

• Vignette - a screen treatment for use in the Scaffold that blurs top and bottom of screen when scrollable content is in use.

• The following components are also included from Wear Compose Foundation:

• CurvedLayout - Wear Foundation CurvedLayout is a layout composable that places its children in an arc, rotating them as needed. This is similar to a Row layout curved into a segment of an annulus. Note that the content of a CurvedLayout is not a composable lambda - rather, it is a DSL (domain-specific language). All elements in the CurvedLayout's DSL support an optional modifier parameter, created from CurvedModifier .

• basicCurvedText - an element in the CurvedLayout DSL, basicCurvedText allows developers to easily write curved text following the curvature of a circle (usually at the edge of a circular screen). basicCurvedText can be only created within the CurvedLayout to ensure the best experience, like being able to specify the positioning, and using CurvedModifiers . Note that in most cases curvedText should be used instead, since it uses Material theming.

• curvedComposable - wraps normal composable content so that it can be used with CurvedLayout . If curvedComposable has several elements inside, they will be drawn on top of each other (like a Box). To put several composables along a curve, wrap each one with curvedComposable .

• curvedRow and curvedColumn - similar to Row and Column, curvedRow and curvedColumn can be nested inside a CurvedLayout to lay elements out as needed. For a curvedRow , the angular layout direction and radial alignment may be specified. For a curvedColumn , the angular alignment and radial direction may be specified.

• CurvedModifier - all curved components accept a modifier parameter that can be created using CurvedModifier : background, size, weight and padding are supported.

• The following component is also included from Wear Compose Navigation:

• SwipeDismissableNavHost - provides a place in the Compose hierarchy for self-contained navigation to occur, with backwards navigation provided by a swipe gesture. Content is displayed within a SwipeToDismissBox , showing the current navigation level. During a swipe-to-dismiss gesture, the previous navigation level (if any) is shown in the background.

• See previous release notes for the various Alpha releases for more details of what has been delivered.

Изменения API

• Added CurvedModifier.padding* functions. These are used to specify additional space to be added around a curved component. ( I4dbb4 )
• Removed CompositionLocal internal class ( I42490 )
• We have added constant values for Button , CompactButton and ToggleButton icon sizes, as guidance ( I57cab )
• Add enabled parameter to AppCard and TitleCard . Now they have a similar API to androidx.compose.material Cards. When the parameter is set to false, the card will not be clickable. ( Idc48d , b/228869805 )

Исправления ошибок

• Stepper now disables the decrease and increase buttons when the lower/upper limits have been reached (and applies ContentAlpha.disabled to the iconColor) ( I4be9f )
• We have added 1dp padding around Picker contents when drawn with a gradient to prevent jitter on text seen when swiping. ( I0b7b9 )
• Add screenshot tests for PositionIndicator ( I5e8bc )
• Add more tests for AppCard and TitleCard ( I85391 , b/228869805 )

Version 1.0.0-alpha21

20 апреля 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha21 , androidx.wear.compose:compose-material:1.0.0-alpha21 , and androidx.wear.compose:compose-navigation:1.0.0-alpha21 are released. Version 1.0.0-alpha21 contains these commits.

Новые функции

• Added new curved modifiers to specify the background of a curved element: CurvedModifier.background , .radialGradientBackground and .angularGradientBackground ( I8f392 )
• Allow curved text overflow mode (clip/ellipsis/visible) to be specified. ( I8e7aa )
• Added CurvedModifier.weight modifier, similar to the one in Compose. This can be used on children of curvedRow and CurvedLayout (for width) and children of curvedColumn (for height). ( I8abbd )
• Added CurvedModifier.size , .angularSize and .radialSize modifiers to specify the size of a curved element. ( I623c7 )

Изменения API

• Reorder parameters to ensure background is before color consistently across the Wear Compose API ( I43208 )
• Removed clockwise & insideOut parameters and replaced with more expressive constants on new classes. Curved layout direction can now be LayoutDirection aware, and it is inherited when not specified ( If0e6a )
• We have replaced autoCenter: Boolean with autoCenter: AutoCentringParams in order to fix an API issue with the ScalingLazyColumn . ( Ia9c90 )
• We have renamed iconTintColor and toggleControlTintColor to iconColor and toggleControlColor throughout the API (Chip/ToggleChip/Dialog/Slider/Stepper/...) as the color is applied to the icon/toggleControl slot. ( Ied238 )
• Rewrite PageIndicatorStyle enum into value class ( I2dc72 )
• We have added RowScope/ColumnScope/BoxScope to some of the slots in our Composables to indicate to developers what the layouts assumptions are. This will allow developers to use additional modifiers on some slot content and avoid the need to provide extra layout elements. Additionally we have made some minor updates to the AppCard/TitleCard colors so that timeColor and appColor default to contentColor , these properties can still all be individually overridden if needed. ( I26b59 )
• Made SwipeToDismissBoxState.Companion object private ( I39e84 )
• Fix parameters order for InlineSlider and Stepper . A simple change to follow api guidelines ( I11fec )
• We have removed the Saver object for SwipeToDismissBoxState as it was not used. ( Ifb54e )
• We have updated CompactChip to bring it inline with the latest UX Specification. Padding has been reduced to horizontal = 12.dp and vertical = 0.dp. The font for label has been changed from button to caption1. The recommended icon sizes are 20x20 when both icon and label are present and 24x24 for an icon only compact chip. For the icon only use case we have also ensured that the icon is center aligned. ( Iea2be )
• We have added a number of new fields to ScalingLazyListLayoutInfo to enable developers to know the amount of contentPadding and autoCenteringPadding that has been applied. These can be useful for developers when calculating fling/scroll ( I7577b )
• We have implemented in/out transitions for Dialog. A showDialog parameter has been added and the Dialog now controls its own visibility (this enables Dialog to run the intro and outro animations when the Dialog is shown/hidden). Note that the outro animation is not performed when the user leaves the dialog via swipe-to-dismiss. We have also added a default value for state in the recently added SwipeToDismissBox overload. ( I682a0 )
• In order to better support i18n and a11y we have changed ToggleChip and SplitToggleChip so that they no longer have a default for the toggleControl slot. We have also changed ToggleChipDefaults so that the following methods now return ImageVector rather than Icon (note that as they no longer return @Composables they have changed to start with lower case), SwitchIcon()->switchIcon() , CheckboxIcon->checkboxIcon() and RadioIcon()->radioIcon() - this allows and encourages developers to create their own Icon() composables with an appropriate contentDescription set. ( I5bb5b )
• We have added a SwipeDismissableNavHostState parameter to SwipeDismissableNavHost . This supports use of edge-swiping on screens used as navigation destinations, because SwipeToDismissBoxState can now be hoisted and used to initialize both SwipeDismissableNavHostState and Modifier.edgeSwipeToDismiss on screens that require edge-swiping. ( I819f5 , b/228336555 )

Исправления ошибок

• Ensure curved layouts are updated when needed. ( Ie8bfa , b/229079150 )
• Bug fix for https://issuetracker.google.com/issues/226648931 ( Ia0a0a , b/226648931 )
• Removed unnecessary experimental annotations ( I88d7e )

Version 1.0.0-alpha20

6 апреля 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha20 , androidx.wear.compose:compose-material:1.0.0-alpha20 , and androidx.wear.compose:compose-navigation:1.0.0-alpha20 are released. Version 1.0.0-alpha20 contains these commits.

Новые функции

• Add edgeSwipeToDismiss modifier for SwipeToDismiss . Allows swipeToDismiss to be active only on the left edge of the viewport. Used when the center of the screen needs to be able to handle horizontal paging, such as 2-d scrolling a Map or swiping horizontally between pages.( I3fcec , b/200699800 )

Изменения API

• Base implementation of CurvedModifiers , this opens the way to introduce ways to customize curved content (but no CurvedModifiers are provided yet, and the ability to create custom modifiers may be available later) ( I9b8df )
• EdgeSwipe modifier documentation and default values update for better understanding .( I6d00d )
• Add PageIndicator slot into Scaffold. By adding PageIndicator directly into Scaffold we might assure that it will be correctly shown on circular devices. ( Ia6042 )
• Remove default Icons from InlineSlider and Stepper parameters. This will help developers to be more attentive to localization and accessibility requirements. Usages of default icons were shown in demos and samples. ( I7e6fd )
• Replace Trailing and Leading parameter names with Start and End in TimeText ( Iaac32 )
• We have added a SwipeToDismissBox overload with an onDismissed parameter to support the common usage of triggering a navigation event when the swipe gesture has completed. ( I50353 , b/226565726 )
• Removed ExperimentalWearMaterialApi annotations from TimeText usage ( Ide520 )
• We have marked ScalingLazyList/Column scope and info interfaces as sealed as they are not intended for external developers to implement and this will allow us to add new members in them in future without binary breaking changes. ( I7d99f )
• We have added a new flingBehaviour property to the Picker and a PickerDefaults.flingBehaviour() method to enable configuration of the fling behavior such as adding RSB support. PickerState now implements the ScrollableState interface. ( Ib89c7 )

Исправления ошибок

• Update the Android Runtime (ART) baseline profile rules for Wear Compose libraries. ART can leverage profile rules on devices in order to compile ahead-of-time a specific subset of the application to improve the performance of the application. Note that this will have no effect on debuggable applications. ( Iaa8ef )
• Improve documentation ( I2c051 )

Version 1.0.0-alpha19

23 марта 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha19 , androidx.wear.compose:compose-material:1.0.0-alpha19 , and androidx.wear.compose:compose-navigation:1.0.0-alpha19 are released. Version 1.0.0-alpha19 contains these commits.

Изменения API

• Renamed CurvedRow to CurvedLayout , and reworked to be a scope with a DSL. Using this DSL, more complex curved layouts can be specified using a series of nested curvedRow and curvedColumn (Which are the curved layout equivalents of Row and Column). Inside these layout elements, three elements can be used: curvedComposable (to add any @Composable), basicCurvedText (foundation's curved text) and curvedText (wear material aware curved text). ( Ib776a )
• Make the side for the PositionIndicator configurable. The basic PositionIndicator's position can now be configured to be End (layout direction-aware), OppositeRsb (takes into account screen rotation, to position itself opposite to the physical RSB), or the absolutes Left & Right. ( I2f1f3 )
• For SwipeToDismissBox , we have renamed SwipeDismissTarget .Original to SwipeToDismissValue.Default and SwipeDismissTarget.Dismissal to SwipeToDismissValue.Dismissed . We have also moved SwipeToDismissBoxDefaults.BackgroundKey and SwipeToDismissBoxDefaults.ContentKey to SwipeToDismissKeys.Background , SwipeToDismissKeys.Content respectively. ( I47a36 )
• We have added a read-only mode to Picker, for screens with multiple Pickers where only one Picker is editable at a time. When the Picker is read-only, it displays the currently selected option, and a label if one has been provided. ( I879de )
• SwipeToDismissBoxState has been refactored to restrict the scope of ExperimentalWearMaterialApi to Modifier.swipeable and SwipeableState , which are now used internally. SwipeToDismissBoxState now has currentValue , targetValue , isAnimationRunning and snapTo members to support common use cases - please let us know if you require any further properties to be made available. Also fixed the behavior of SwipeableState in the case where the swipe offset is within a rounding error of an anchor. ( I58302 )

Исправления ошибок

• Simplified and fixed code to detect if the content of a ScalingLazyColumn can be scrolled (used to decide if we display a scrollbar or not) ( I7bce0 )
• Fixed a bug on Position Indicator when used with more than one state and switching between them ( I320b5 )
• We have updated the default Compose for Wear OS theme typography/fonts to match our latest UX guidance. Of note display1 (40.sp) and display2 (34.sp) are now smaller than their previous values and various other minor updates to line height and line spacing have been made. ( Ie3077 )
• We have added resistance to SwipeToDismissBox so that motion only happens when swiping to dismiss and not at all in the opposite direction. ( Ifdfb9 )
• We have changed some of the default parameter values for the CircularProgressIndicator functions to bring them in-line with Wear Material Design UX guidance. For the Spinner/Indeterminant version the size (40->24.dp), indicatorColor (primary->onBackground), trackColor transparency (30%->10%) and stroke width (4->3dp) have been updated. For the Progress/Determinate version the trackColor transparency (30%->10%) has been updated. ( I659cc )
• We have updated the default scaling params of the ScalingLazyColumn in-line with the latest Wear Material Design UX specifications. Visually this results in list items starting to be scaled closer to the list center, but being less scaled at the list edge than before. ( Ica8f3 )
• Some adjustments to ScalingLazyColumnDefaults.snapFlingBehavior to improve the end of the animation ( If3260 )

Version 1.0.0-alpha18

9 марта 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha18 , androidx.wear.compose:compose-material:1.0.0-alpha18 , and androidx.wear.compose:compose-navigation:1.0.0-alpha18 are released. Version 1.0.0-alpha18 contains these commits.

Изменения API

• Several improvements to PositionIndicator: ShowResult renamed PositionIndicatorVisibility. Some performance improvements to avoid recomputations when not needed ( Iaed9d )
• The recommended coloring for the SplitToggleChip has been updated. SplitToggleChip's now have a solid colored background when checked or unchecked with the coloring of the ToggleControl being the primary indication of whether the component is checked or not. We have added a new ToggleDefaults.splitToggleChipColors() to support the new color scheme. We have also simplified the toggleChipColors() methods removing the splitBackgroundOverlayColor ( I7e66e )
• We have added unadjustedSize to the ScalingLazyListItemInfo as it is not safe to calculate the original item size using the scaled size and scaling factor due to float maths precision. ( I54657 , b/221079441 )
• Add HorizontalPageIndicator . It represents a total number of pages and a selected page. Might be linear or curved, depending on the shape of the device. It also supports custom indicator shape, which defines how each indicator is visually represented. ( Iac898 )
• We have updated PickerState so that the numberOfOptions can be updated. This supports use-cases such as a DatePicker , when the number of days in the month changes depending on the month selected. The constructor parameter for PickerState has changed to initialNumberOfOptions accordingly. ( Iad066 )
• Hide the PositionIndicator when is a scrollbar and can't scroll. ( Id0a7f )
• For consistency with Scaffold, our full-screen Dialog component now displays a PositionIndicator and a Vignette . We are also now using ScalingLazyColumn instead of Column , which means that the Dialog contents are now in ScalingLazyListScope (and typically need to be enclosed by item { /* content */ }). Dialog supports the verticalArrangement parameter accordingly. ( Idea13 )
• We have changed the name of ToggleChip and SplitToggleChip toggleIcon property to toggleControl to better align with Material Design in order to help designers and developers navigate the API. ( If5921 , b/220129803 )
• We have added a new entry caption3 to the Wear Material Theme Typology.Caption3 is a small font used for the extra long-form writing like legal texts. ( I74b13 , b/220128356 )

Исправления ошибок

• Stop the snapping animation when we are there. ( Idb69d )
• Animate changes in PositionIndicator. ( I94cb9 )
• Based on UI/UX feedback we have changed the ScalingLazyColumn autoCentering so that it will provide only enough space to make sure the items with index ScalingLazyListState.initialCenterItemIndex or higher will be able to be fully scrolled to the center of the viewport. This allows developers to place one or two items about the item initially in the center which are not scrollable into the middle. This will mean that an autoCenter'ing ScalingLazyColumn will not be able to scroll above the initialCenterItemIndex/initialCenterItemScrollOffset ( I22ee2 )
• We have added a demo for a Date Picker and fixed a bug in PickerState where the initiallySelectedOption was not applied until the Picker had been displayed. ( Id0d7e )
• In order to reduce the clipping of wider ScalingLazyColumn items on circular screens we have increased the default horizontal content padding from 8 to 10 dp. ( I0d609 )
• Ensure the PositionIndicator is shown when scrolling. ( Ied9a2 )

Version 1.0.0-alpha17

23 февраля 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha17 , androidx.wear.compose:compose-material:1.0.0-alpha17 , and androidx.wear.compose:compose-navigation:1.0.0-alpha17 are released. Version 1.0.0-alpha17 contains these commits.

Новые функции

• We have added snap support that can be used with ScalingLazyColumn . Set flingBehavior = ScalingLazyColumnDefaults.flingWithSnapBehavior(state) to enable snap support. ( I068d3 , b/217377069 )
• We have added demos for Picker used to select a time in either 24 hour or 12 hour clock. ( Ie5552 )

Изменения API

• Fix an issue with TimeText custom fonts & styles on square device ( Iea76e )
• ScalingLazyListLayoutInfo now has reverseLayout , viewportSize and orientation properties matching those from LazyListLayoutInfo ( I4f258 , b/217917020 )
• ScalingLazyColumn now has a userScrollEnabled property matching that from LazyList ( I164d0 , b/217912513 )
• Pickers now have a gradient on the top and bottom by default ( Iab92a )

Исправления ошибок

• We have modified ScalingLazyColumn so that it no longer greedily fills all of the space in its parent. Instead it will take its size from the size of its contents. This makes it consistent with the behaviour of LazyColumn . If you want to reinstate the old behaviour then pass Modifier.fillMaxWidth()/width()/widthIn() to the ScalingLazyColumn ( I51bf8 )
• We have improved the exception message in SwipeDismissableNavHost.kt that was triggered if the navigation backstack was empty. ( I1b1dc )

Version 1.0.0-alpha16

9 февраля 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha16 , androidx.wear.compose:compose-material:1.0.0-alpha16 , and androidx.wear.compose:compose-navigation:1.0.0-alpha16 are released. Version 1.0.0-alpha16 contains these commits.

Новые функции

• Add CircularProgressIndicator . Progress indicators display the length of a process or an unspecified wait time. Supports a gap (cutout) for TimeText or other components if used full-screen. ( Iab8da )

Изменения API

• Pickers now have a flingBehavior parameter, the default value makes them snap to the closest option when scrolling/flinging. ( I09000 )
• Additional integer API for InlineSlider and Stepper ( I1b5d6 )

Исправления ошибок

• We have changed the default initialCenterItemIndex for the ScalingLazyListState from 0->1. This means that unless overridden on state construction with ScalingLazyListState.rememberScalingLazyListState(initialCenterItemIndex = ) then the 2nd list item (index == 1) will be placed in the center of the viewport at initialization and the 1st (index == 0) item will be placed before it. This allows for a better default visual effect out of the box as most of the viewport will be filled with list items. ( I0c623 , b/217344252 )
• We have reduced the ScalingLazyColumn default extraPadding that is provided to ensure that there are plenty of list items to draw (even when we are scaling some of them down in size) from 10% to 5%. This will avoid composing extra list items that might not appear in the viewport. If non standard scalingParams are being used (more extreme scaling for instance) the developer can adjust extra padding using viewportVerticalOffsetResolver . ( I76be4 )
• Fix an issue with TimeText on multiple lines on square device ( Ibd3fb )
• We have modified ScalingLazyColumn so that it no longer greedily fills all of the space in its parent. Instead it will take its size from the size of its contents. This makes it consistent with the behavior of LazyColumn . If you want to reinstate the old behavior then pass Modifier.fillMaxSize() to the ScalingLazyColumn - NOTE: This change is incomplete and will be addressed in a follow up change in the next Alpha release. ( I3cbfa )

Version 1.0.0-alpha15

26 января 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha15 , androidx.wear.compose:compose-material:1.0.0-alpha15 , and androidx.wear.compose:compose-navigation:1.0.0-alpha15 are released. Version 1.0.0-alpha15 contains these commits.

Изменения API

• We have added a new property autoCentering to the ScalingLazyColumn . When true (the default) this will ensure that all items including the first and last can be scrolled so that they are visible in the center of the lists viewport. Note that if using auto-centering you will probably want to set vertical content padding to 0.dp. If both autoCentering and vertical content padding are provided then they will both result in additional space being available before the first and after the last list items allowing them to be scrolled even further. ( I2a282 , b/214922490 )
• We have added a Dialog component that enables any composable to trigger a full screen dialog that sits on top of other content. When shown, the dialog supports swipe-to-dismiss and will show its parent's content in the background during the swipe gesture. The dialog content is expected to be Alert or Confirmation (renamed from earlier components AlertDialog and ConfirmationDialog ) - Alert , Confirmation and Dialog are all in the androidx.wear.compose.material.dialog package. Alert and Confirmation can be used as navigation destinations. Also, added ColumnScope to Alert and Confirmation parameters as necessary. ( Ia9014 )
• We have removed onSurfaceVariant2 from the Compose for WearOS Material Theme Colors and replaced uses in the library with onSurfaceVariant . ( Icd592 )
• Added a method to programmatically select an option on the PickerState , the initially selected option can now also be specified when creating a PickerState . ( I92bdf )
• We have added support for customizing the fling behavior of the ScalingLazyColumn . ( I1ad2e , b/208842968 )
• We have added NavController.currentBackStackEntryAsState() to the Wear.Compose.Navigation library. ( If9028 , b/212739653 )
• Added Modifier.onRotaryScrollEvent() and Modifier.onPreRotaryScrollEvent() for Wear devices with a rotating side button.( I18bf5 , b/210748686 )

Version 1.0.0-alpha14

12 января 2022 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha14 , androidx.wear.compose:compose-material:1.0.0-alpha14 , and androidx.wear.compose:compose-navigation:1.0.0-alpha14 are released. Version 1.0.0-alpha14 contains these commits.

Новые функции

• We have added a number of methods to ScalingLazyListState to allow developer control over scrolling to specific list items and also setting the initial list item and offset.

  As part of this change we have also modified the ScalingLazyList so that it is oriented around the center of the viewport of the ScalingLazyList rather than the start of the viewport.

  A new property anchorType: ScalingLazyListAnchorType = ScalingLazyListAnchorType.ItemCenter has been added to the ScalingLazyList to control whether the center ( ScalingLazyListAnchorType.ItemCenter ) or Edge ( ScalingLazyListAnchorType.ItemStart ) should be aligned to the viewport's centerline.

  As a result the ScalingLazyListItemInfo.offset and ScalingLazyListItemInfo.adjustedOffset have changed and will now reflect the offset of the item with respect to both the position of the list item and the anchorType of the list. Eg for a ScalingLazyColumn with anchorType of ItemCenter and an list item positioned with its center on the centerline of the viewport the offset would be 0 .

  The new methods are scrollTo , animatedScrollTo , centerItemIndex , and centerItemOffset . ( I61b61 )

• We have added a back button handler to SwipeDismissableNavHost , so that pressing back navigates to the previous level in the navigation hierarchy. ( I5b086 , b/210205624 )

Version 1.0.0-alpha13

15 декабря 2021 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha13 , androidx.wear.compose:compose-material:1.0.0-alpha13 , and androidx.wear.compose:compose-navigation:1.0.0-alpha13 are released. Version 1.0.0-alpha13 contains these commits.

Изменения API

• We have made RangeIcons internal (referenced internally by InlineSlider and Stepper ). ( I927ec )

Исправления ошибок

• Fixed an issue where SwipeDismissableNavHost would add a destination to the Compose hierarchy before it has reached the CREATED Lifecycle state, resulting in an IllegalStateException . This fix was a prerequisite to updating dependency on navigation-compose to 2.4.0-beta02 and beyond. ( I40a2b , b/207328687 )

• Added a Drawables enum class for getting drawable resources within the Wear Compose library, so that reflection is no longer needed. This fixes a bug where library drawables were removed when minifyEnabled=true or shrinkResources=true ). ( Ib2a98 )

• Added tests for Stepper in Wear Compose ( I2d03a )

• Added samples for SwipeDismissableNavHost in Wear Compose Navigation. ( I85f06 )

Version 1.0.0-alpha12

1 декабря 2021 г.

Новые функции

• We have added a Stepper component which allows users to make a selection from a range of values. Stepper is a full-screen control with increase and decrease buttons at the top and bottom, and a slot in the middle (expected to take either a Chip or Text). The button icons can be customized if required. ( I625fe )

• We have added 2 new composables for displaying dialogs: AlertDialog waits for a response from the user and displays a title, icon, message and either a) two buttons for simple positive/negative choices or b) vertically stacked chips or toggle chips for more flexible choices, ConfirmationDialog displays an acknowledgement with a timeout. This simple dialog has slots for a title and an (animated) icon. ( Ic2cf8 )

Изменения API

Новые функции

• We have added a picker component that lets the user select an item from a scrolling list. By default, the list of selectable items is repeated 'infinitely' in both directions, to give the impression of a rotating cylinder seen from the side. Two features will be added in later releases: snapping to a value after a swipe/fling; adding a function to PickerState to set/scroll to the current value. ( I6461b )

Изменения API

• Added a ScalingLazyItemScope and some new modifiers fillParentMaxSize/fillParentMaxWidth/fillParentMaxHeight to allow list items to be sized based on the size of the parent container. Items can be set to fill all or a fraction of the parent's size. This exposes functionality already available in the LazyRow/Column ( I4612f )
• Added support to ScalingLazyColumn to allow items to have a key. Also added convenience methods to allow adding of items from Arrays and Lists. ( Ic1f89 )

Новые функции

• Added a CurvedText component in material, a component allowing developers to easily write curved text following the curvature of a circle (usually at the edge of a circular screen). ( I19593 )

Изменения API

• Added tests for TimeText ( Idfead )
• Transform ArcPaddingValues into an interface. ( Iecd4c )
• Added animation to SwipeToDismissBox ( I9ad1b )
• Added hasBackground parameter to the SwipeToDismissBox API so that the swipe gesture can be disabled when there is no background content to display. ( I313d8 )
• rememberNavController() now takes a optional set of Navigator instances that will be added to the returned NavController to better support optional Navigators such as those from Accompanist Navigation Material . ( I4619e )
• Reference NamedNavArgument from navigation-common and remove copy from wear.compose.navigation. ( I43af6 )

Исправления ошибок

• Fixed CurvedRow test flakiness on smaller devices. ( If7941 )
• Fixed possible flickering on CurvedRow when the content updates, and ensures the curved row is remeasured ( Ie4e06 )
• ChipDefaults.gradientBackgroundChipColors() has been updated in line with UX Spec changes. The gradient now starts with MaterialTheme.colors.primary with alpha 32.5% and ends with MaterialTheme.colors.surface with alpha @ 0% over a background of MaterialTheme.colors.surface @ 75% alpha. ( Id1548 )
• We have updated the colors for ToggleChips when in the selected state to match the latest Wear Material Design UX Spec guidance. When selected ToggleChips now have a gradient background from MaterialTheme.color.surface @ 0% alpha, top left, to MaterialTheme.color.primary @ 32% alpha, bottom right, over a background of MaterialTheme.color.surface @ 75% alpha. This results in a more subtle difference between checked and unchecked for the ToggleChip. ( Idd40b )

Версия 1.0.0-альфа06

15 сентября 2021 г.

androidx.wear.compose:compose-foundation:1.0.0-alpha06 , androidx.wear.compose:compose-material:1.0.0-alpha06 , and androidx.wear.compose:compose-navigation:1.0.0-alpha06 are released. Version 1.0.0-alpha06 contains these commits.

Новые функции

• We have added Scaffold a top level application composable that provides a structure for handling PositionIndicators (like Scroll or Volume) position, an area at the top of the screen for displaying the time and application status, and also supports a Vignette to blur the screen top and bottom edge for scrollable content. The main area of the Scaffold is where the application contents are placed. ( I5e0bf )
• Added TimeText implementation for Wear Compose ( I5654c )

Wear Compose Navigation Library

• We have added the first release of the Wear Compose Navigation library, which provides integration between the Wear Compose and Androidx Navigation libraries. It provides a simple means to navigate between @Composable functions as the destinations in your application.

• This initial release provides:

  • A SwipeDismissableNavHost composable that hosts a navigation graph and provides backwards navigation via swipe gestures
  • NavGraphBuilder.composable extension to assist with constructing navigation graphs
  • rememberSwipeDismissableNavController() to allow hoisting state

• Example usage where we create two screens and navigate between them:

  val navController = rememberSwipeDismissableNavController()
  SwipeDismissableNavHost(
      navController = navController,
      startDestination = "start"
  ) {
      composable("start") {
          Column(
              horizontalAlignment = Alignment.CenterHorizontally,
              verticalArrangement = Arrangement.Center,
              modifier = Modifier.fillMaxSize(),
          ) {
              Button(onClick = { navController.navigate("next") }) {
                  Text("Go")
              }
          }
      }
      composable("next") {
          Column(
              horizontalAlignment = Alignment.CenterHorizontally,
              verticalArrangement = Arrangement.Center,
              modifier = Modifier.fillMaxSize(),
          ) {
              Text("Swipe to go back")
          }
      }
  }
  

• Wear Compose Navigation is packaged as a separate library so that simple WearCompose applications that implement their own hand-rolled navigation are not required to depend on the Androidx Navigation library.

Изменения API

• Updated SwipeDismissableNavHost to support rememberSaveable by setting the key identity for background and content ( I746fd )
• We have added a PositionIndicator adapter that can handle LazyListState ( I21b88 )
• Updated SwipeToDismissBox to support rememberSaveable ( Ie728b )
• We have added reverseLayout support to the ScalingLazyColumn. This allows for the reversing of the direction of scrolling and layout ( I9e2fc )
• Deprecated performGesture and GestureScope , which have been replaced by performTouchInput and TouchInjectionScope . ( Ia5f3f , b/190493367 )
• We have renamed VignetteValue to VignettePosition and renamed VignetteValue.Both renamed to VignettePosition.TopAndBottom. ( I57ad7 )
• We have renamed ScalingLazyColumnState to ScalingLazyListState, ScalingLazyColumnItemInfo to ScalingLazyListItemInfo, ScalingLazyColumnLayoutInfo to ScalingLazyListLayoutInfo and ScalingLazyColumnScope to ScalingLazyListScope in case we decide to add a ScalingLazyRow implementation in the future. ( I22734 )

Исправления ошибок

• Updated CompactChip documentation to describe what happens if neither an icon nor a label is provided. ( I4ba88 )
• We have made some adjustments to the Wear card components. ( I6b3d0 )
  1. TitleCard spacing between Title and Body reduced from 8.dp to 2.dp.
  2. TitleCard header font changed from body to title3.
  3. Card background gradient changed to make the background appear darker.

Новые функции

Wear Compose is a Kotlin, Compose-based library that supports Wear Material design, an extension of Material Design for WearOS wearables. This first alpha release contains early, functional implementations of the following:

• Material theme - configures the colors, typography and shapes consistently across the components used from this library.
• Chip, CompactChip - chips are stadium shaped and variations are available to take icon, label and secondary label content.
• - ToggleChip, SplitToggleChip - a specialized type of chip that includes a slot for a bi-state toggle icon such as a radio button or checkbox. In addition, the SplitToggleChip has two tappable areas, one clickable and one toggleable.
• Button, CompactButton - buttons are circular in shape, with a single content slot for an icon or minimal text (maximum 3 characters).
• ToggleButton - a button that turns an action on or off, with a single slot for icon or minimal text (maximum 3 characters).
• Card, AppCard - rectangular shaped with rounded corners, offering slots for content such as app icon, time, title and body.

Future releases will extend the Widget set adding support for Wear Material Design pickers, sliders, lists, page indicators, dialogs, scroll rsb indicators, toasts and more.

Additionally support will be provided for other Wearable Specific features such as curved layouts and text, as well as scaffolding to make it easy for developers to build Wearable apps/overlays.

Wear Compose Material is designed with the same principles as Compose Material, although being targeted at wearables. The Wear Compose Material library should be used in place of the Compose Material library when building for a Wearable device.

The two “Material” libraries should be considered mutually exclusive and should not be mixed in the same app. If developers find themselves including the Compose Material library in their dependencies it would suggest that either a) there are components missing from the Wear Compose Material library, please let us know what you need, or b) are using a component that we do not recommend for use on a Wearable Device.
