在下面的代码ACTION_WIDGET_CLICKED不起作用...有人知道为什么吗？ MY_WIDGET_UPDATE工作正常。收到敬酒后，我再也看不到intent.getAction()了ACTION_WIDGET_CLICKED。看来我哪里出错了，按钮单击不会创建广播...

我还区分了 istances 之间的点击，小部件的每个 istances 都有不同的操作要做ACTION_WIDGET_CLICKED。示例：在updateAppWidget我必须仅将appWidgetId单击的小部件传递给 Toast

似乎您没有调用where被调用appWidgetManager.updateAppWidget(...)的正确实例。它应该是这样的：updateViewssetOnClickPendingIntent

final RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);            
updateViews.setTextViewText(...);
...
Intent intent = new Intent(context, MyWidget.class);
intent.setAction(ACTION_WIDGET_CLICKED+String.valueOf(appWidgetId));
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
updateViews.setOnClickPendingIntent(R.id.mywidget_id, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, updateViews);

并在OnReceive：

String action = intent.getAction();
if (action.startsWith(ACTION_WIDGET_CLICKED))
{
  int widgetId = Integer.parseInt(action.substring(ACTION_WIDGET_CLICKED.length()));
  ...
}
