Question

我发送一个带有pendingIntent的动作，但是onRecieve（）无法看到这个动作？我怎么处理呢？

我没有接受任何错误。当我看日志。我只看到了UPDATE，ENABLED，DISABLE，DELETED动作

公共类WidgetDeneme扩展了AppWidgetProvider {

final String TAG = WidgetDeneme.class.getSimpleName();
final String APPWIDGET_BUTTON_CLICK = "android.appwidget.action.APPWIDGET_BUTTON_CLICK";

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    super.onUpdate(context, appWidgetManager, appWidgetIds);
    Log.e(TAG,TAG);
    final int N = appWidgetIds.length;

    // Perform this loop procedure for each App Widget that belongs to this provider
    for (int i=0; i<N; i++) {
        int appWidgetId = appWidgetIds[i];

        // Create an Intent to launch ExampleActivity
        Intent intent = new Intent(context,WidgetDeneme.class);
        intent.setAction(APPWIDGET_BUTTON_CLICK);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

        // Get the layout for the App Widget and attach an on-click listener
        // to the button
        RemoteViews views = new RemoteViews(context.getPackageName(), PendingIntent.FLAG_UPDATE_CURRENT);
        views.setOnClickPendingIntent(R.id.imageView, pendingIntent);

        // Tell the AppWidgetManager to perform an update on the current app widget
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }
}

@Override
public void onReceive(Context context, Intent intent) {
    Log.e(TAG,intent.getAction());
    super.onReceive(context, intent);
}

}

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <receiver android:name=".WidgetDeneme" >
        <intent-filter>

            <action android:name="android.appwidget.action.APPWIDGET_BUTTON_CLICK" />

        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/appwidget_info" />
    </receiver>

    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
    </activity>
</application>

确保使用正确的布局

创建RemoteViews

    // Create an Intent to launch ExampleActivity
    Intent intent = new Intent(context,WidgetDeneme.class);
    intent.setAction(APPWIDGET_BUTTON_CLICK);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

    // Get the layout for the App Widget and attach an on-click listener
    // to the button
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
    views.setOnClickPendingIntent(R.id.imageView, pendingIntent);

    // Tell the AppWidgetManager to perform an update on the current app widget
    appWidgetManager.updateAppWidget(appWidgetId, views);

注意R.layout.widget而不是PendingIntent.FLAG_UPDATE_CURRENT。确保您实际使用您为布局指定的名称，您将在res / layout文件夹中找到它。有关详细信息，请参阅Android developer page。
