我正在尝试从我的小部件提供程序启动一项服务,以在方向更改时更新小部件。问题是服务似乎没有启动。谁能看到我做错了什么?这就是我现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;
}
}
}
