我创建了一个小部件，用于检索 html 原始数据并将其解析出来。数据正确显示到小部件，但是当我启动小部件的配置活动并退出时，小部件布局被重置，小部件上没有显示任何内容，所有文本都被删除。该小部件在 android 4.0 上完美运行并且没有此问题，但在 2.3.3 上它具有此行为。关于问题是什么以及如何解决它的任何想法？

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

       WidgetIds = appWidgetIds;
       try {BUP.backupWidgetIdLength(context,  WidgetIds.length);} catch (Exception e1) {e1.printStackTrace();}
       for(int i = 0; i < WidgetIds.length; i++)
       {
        try {BUP.backupWidgetIds(context, WidgetIds[i], i);
            } catch (Exception e) {e.printStackTrace();}
       }


          super.onUpdate(context, appWidgetManager, appWidgetIds);
          //updateWidget(context,appWidgetIds);
          final int N = appWidgetIds.length;
          for (int i=0; i<N; i++) {
              int appWidgetId = appWidgetIds[i];

              updateWidget(context,appWidgetId);

          }

    Intent intent = new Intent(context, MySchedule.class);

            AppWidgetManager appWidgetMan = AppWidgetManager.getInstance(context);
            ComponentName thisWidget = new ComponentName(context, MySchedule.class);
            appWidgetMan.updateAppWidget(thisWidget, updateViews);

        }catch(Exception e)
        {
            Log.d("Error_OnUpdate",e.getMessage());
        }

}

   }
