Question

我正在尝试从我的窗口小部件提供程序启动服务，以更新方向更改窗口小部件。问题是该服务似乎没有启动。谁能看到我做错了什么？这就是我现在在代码中的全部内容。

public class PSWidgetProvider extends AppWidgetProvider {

    private static Handler      handler             = new Handler();
    private static Runnable     runnable;
    public static int           currentAlarmSet     = 0;

    @Override
    public void onReceive(final Context context, Intent intent) {
        // TODO Auto-generated method stub
        super.onReceive(context, intent);

    }

    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

        context.startService(new Intent(context, MyUpdateService.class));

    }


    public static class MyUpdateService extends Service
    {
        @Override
        public void onStart(Intent intent, int startId)
        {
            Log.i("MyUpdateService", "onStart");
            super.onStart(intent, startId);
            // Update the widget
            RemoteViews remoteViews = buildRemoteView(this);

            // Push update to homescreen
            pushUpdate(remoteViews);

            // No more updates so stop the service and free resources
            stopSelf();
        }

        public RemoteViews buildRemoteView(Context context)
        {
            RemoteViews updateViews = null;

            updateViews = new RemoteViews(context.getPackageName(), R.layout.widget_powersleep_layout);
            // Your code to build and update the remote view


            return updateViews;
        }

        @Override
        public void onConfigurationChanged(Configuration newConfig)
        {
            int oldOrientation = this.getResources().getConfiguration().orientation;

            if(newConfig.orientation != oldOrientation)
            {
                // Update the widget
                RemoteViews remoteViews = buildRemoteView(this);

                // Push update to homescreen
                pushUpdate(remoteViews);
            }
        }

        private void pushUpdate(RemoteViews remoteViews)
        {
            ComponentName myWidget = new ComponentName(this, PSWidgetProvider.class);
            AppWidgetManager manager = AppWidgetManager.getInstance(this);
            manager.updateAppWidget(myWidget, remoteViews);
        }

        @Override
        public IBinder onBind(Intent arg0) {
            // TODO Auto-generated method stub
            return null;
        }
    }

}

Answer 1

想出来，服务名称应该是android:name=".receiver.PSWidgetProvider$MyUpdateService" 因为它是一个静态的内部类。

Android：无法从WidgetProvider启动服务
