在窗口小部件中更改图像

Question

如何在我的窗口小部件中有一个图像,然后当它的点击更改为另一个图像？它只是一个只有一个ImageButton的小部件,但是我不知道在这之后去哪里,我知道所有关于待定意图等等,但这在这里没有用,除非我遗漏了什么......这是我的onUpdate

public void onUpdate(Context context,AppWidgetManager appWidgetManager,int[] appWidgetIds){
   RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
   PendingIntent onPendingIntent = PendingIntent.getService(context, 0, new Intent(context, widgetService.class), 0);
   remoteViews.setOnClickPendingIntent(R.id.ImageButton01, onPendingIntent);
   appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
 }

我想这就是你要找的东西

 /* get the handle on your widget*/
 RemoteViews views = new RemoteViews(getPackageName(), R.layout.your_widget_layout);
 /* replace the image */
 views.setBitmap(R.id.id_of_your_imageview, "setImageBitmap", yourBitmap);

 /* update your widget */
 ComponentName thisWidget = new ComponentName(this, YourWidget.class);
 AppWidgetManager manager = AppWidgetManager.getInstance(this);
 manager.updateAppWidget(thisWidget, updateViews);
