调用Widget onUpdate()但列表视图中的数据不会更改

它在第一次将小部件放置在屏幕时加载正确的数据然后在1小时后调用onUpdate(),但内部的数据不会更新

AppWidget_4X3.java

public class AppWidget_4X3 extends AppWidgetProvider {

@Override

}

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

        Intent intent = new Intent(context, widget_Update_Service.class);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
        intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
        RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.app_widget_4_x3);
        rv.setRemoteAdapter(appWidgetIds[i], R.id.widget_list_view_4_x3, intent);
        rv.setEmptyView(R.id.widget_list_view_4_x3, R.id.empty_view);
        appWidgetManager.updateAppWidget(appWidgetIds[i], rv);
    }

    super.onUpdate(context, appWidgetManager, appWidgetIds);
}
}
