在搭載 Android 8.0 (API 級別 26) 以上版本的裝置上,啟動器可以 使用者也可以建立固定捷徑 ,讓他們將小工具固定在主畫面上。與固定捷徑類似 固定式小工具可讓使用者存取應用程式中的特定工作, 新增至應用程式主畫面,如以下影片所示。
![回應式版面配置範例](https://developer.android.com/static/images/appwidgets/widget_pinning.gif?hl=zh-tw)
允許使用者固定小工具
在應用程式中,您可以要求系統將小工具固定在 支援的啟動器,步驟如下:
在
requestPinAppWidget()
敬上 方法,如以下程式碼片段所示:
Kotlin
val appWidgetManager = AppWidgetManager.getInstance(context) val myProvider = ComponentName(context, ExampleAppWidgetProvider::class.java) if (appWidgetManager.isRequestPinAppWidgetSupported()) { // Create the PendingIntent object only if your app needs to be notified // when the user chooses to pin the widget. Note that if the pinning // operation fails, your app isn't notified. This callback receives the ID // of the newly pinned widget (EXTRA_APPWIDGET_ID). val successCallback = PendingIntent.getBroadcast( /* context = */ context, /* requestCode = */ 0, /* intent = */ Intent(...), /* flags = */ PendingIntent.FLAG_UPDATE_CURRENT) appWidgetManager.requestPinAppWidget(myProvider, null, successCallback) }
Java
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); ComponentName myProvider = new ComponentName(context, ExampleAppWidgetProvider.class); if (appWidgetManager.isRequestPinAppWidgetSupported()) { // Create the PendingIntent object only if your app needs to be notified // when the user chooses to pin the widget. Note that if the pinning // operation fails, your app isn't notified. This callback receives the ID // of the newly pinned widget (EXTRA_APPWIDGET_ID). PendingIntent successCallback = PendingIntent.getBroadcast( /* context = */ context, /* requestCode = */ 0, /* intent = */ new Intent(...), /* flags = */ PendingIntent.FLAG_UPDATE_CURRENT); appWidgetManager.requestPinAppWidget(myProvider, null, successCallback); }
