The Watch Face Format is required for watch faces to be installed on devices with Wear OS 5 or later pre-installed and for all new watch faces published on Google Play.
Starting in January 2026, the Watch Face Format will be required for watch faces to be installed on all Wear OS devices.

處理錶面的輕觸操作
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
使用者可以藉由許多方式和錶面互動。舉例來說，使用者可以輕觸錶面瞭解目前播放的歌曲，或查看今天的議程。Wear OS by Google 可讓錶面接受在其特定位置輕觸一下的手勢，前提是沒有其他 UI 元素也會回應該手勢。
如要實作互動式錶面，請先建構錶面樣式，然後按照本指南的說明實作手勢處理。
處理輕觸事件
錶面只會收到輕觸事件，這些事件是指使用者把手指放到螢幕上後再舉起手指。如果使用者手指還在觸控螢幕上，卻執行了其他種類的手勢，錶面便會收到取消事件，因為系統會把其他手勢保留給其他功能使用。
如果想處理輕觸手勢，請用 setTapListener() 新增 TapListener。當使用者輕觸錶面時，便會呼叫事件監聽器。
錶面可以收到以下觸控事件類型：
根據 android.view.ViewConfiguration.getScaledTouchSlop 回傳的值，系統會把 TapType.DOWN 和後續的 TapType.UP 事件驗證為輕觸事件。
由於系統已經處理過該手勢，因此不會在錶面收到 TapType.CANCEL 事件時觸發動作。
詳情請參閱 onTapEvent。
錶面範例應用程式會示範設定錶面的最佳做法。

Wear OS by Google lets watch faces accept\nthe single-tap gesture at a given location on the watch face, as long as there's not another\nUI element that also responds to that gesture.\n\nTo implement an interactive watch face, first construct the\nwatch face style, and then implement gesture handling as described in this guide.\n\nHandle tap events\n-----------------\n\nThe watch face is only given tap events, which are events where the user puts a finger\ndown on the screen and then lifts it. If the user performs any other\ntype of gesture while their finger is on the touchscreen, the watch face receives a\ncancel event, as all other gestures are reserved by the system for other functions.\n\n\nTo handle tap gestures, use\n[`setTapListener()`](/reference/kotlin/androidx/wear/watchface/WatchFace#setTapListener(androidx.wear.watchface.WatchFace.TapListener)) to add a\n[`TapListener`](/reference/kotlin/androidx/wear/watchface/WatchFace.TapListener).\nThe listener is called whenever the user taps on the watch face.\n\nThe watch face receives the following types of touch events:\n\n- TapType.DOWN:\n when the user puts their finger down on the touchscreen\n\n- TapType.UP:\n when the user lifts the finger from the touchscreen\n\n- TapType.CANCEL:\n when the system detects that the user performs a gesture other than a tap\n\nA\n`TapType.DOWN` event and the successive `TapType.UP`\nevent are verified as a tap according to the value returned by\n[android.view.ViewConfiguration.getScaledTouchSlop](/reference/android/view/ViewConfiguration#getScaledTouchSlop()).\n\nDon't trigger an action when the watch face receives a `TapType.CANCEL`\nevent, because the system is already processing the gesture.\n\nFor more information, see [onTapEvent](https://developer.android.com/reference/androidx/wear/watchface/WatchFace.TapListener#onTapEvent(kotlin.Int,androidx.wear.watchface.TapEvent,androidx.wear.watchface.ComplicationSlot)).\n\nRelated resources\n-----------------\n\n\nThe\n[watch face sample app](https://github.com/android/wear-os-samples) demonstrates the best practices for configuring a watch face."]]
