android - 更改小部件中的图像

Question

如何在我的小部件中放置一个图像，然后在单击它时更改为另一张图像？它是一个只有 ImageButton 的小部件，但我不确定此后该去哪里，我知道所有有关待决 Intent 等的信息，但这在这里没有帮助，除非我错过了一些东西......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);
 }

我想这就是你想要的

 /* 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);
