widget - OnClick 小部件更改小部件的文本

Question

有人可以告诉我在 appwidget 提供程序中为小部件使用什么 onclicklistener。

当用户单击小部件时，视图必须更改。

提前致谢！

You can use onUpdate in the widgetProvider for that:(this would open taskmanageractivity in this case)

 @Override
 public void onUpdate(Context context, AppWidgetManager appWidgetManager,
   int[] appWidgetIds) {
   for (int i = 0; i < appWidgetIds.length; i++) {
     int appWidgetId = appWidgetIds[i];

     Intent intent = new Intent(context, TaskManagerActivity.class);
     PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

     RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
     views.setOnClickPendingIntent(R.id.widget_layout, pendingIntent);
     appWidgetManager.updateAppWidget(appWidgetId, views);
   }
 }
