Question

我已经使用闹钟管理器安排了android通知但我无法取消通知，我尝试使用此notificationManager.cancelAll();取消它不起作用然后我试图取消闹钟管理器本身，不幸的是，不起作用。

有谁知道如何取消预定通知？

这就是我为通知设置警报管理器的方法：

Intent myIntent = new Intent(DirctActivityfinal3.this, MyReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(DirctActivityfinal3.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, timeOff9.getTimeInMillis(), pendingIntent);

我尝试使用此代码取消警报管理器，但无法正常工作我仍然收到通知

Intent intent = new Intent(ViewTicketActivity.this, DeleteNotification.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(ViewTicketActivity.this,0, intent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE); 
alarmManager.cancel(pendingIntent);

Answer 1

你的PendingIntents不一样。

要取消警报，您为取消警报而创建的待处理意图必须与您创建警报的意图相同。

e，在你的例子中，你将不同的类传递给每个。

Intent myIntent = new Intent(DirctActivityfinal3.this, MyReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(DirctActivityfinal3.this, 0, myIntent, 0);

与

不同

Intent intent = new Intent(ViewTicketActivity.this, DeleteNotification.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(ViewTicketActivity.this,0, intent, 0);

完成示例：

Intent myIntent = new Intent(myContext, MyReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(myContext, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

然后

alarmManager.set(AlarmManager.RTC_WAKEUP, timeOff9.getTimeInMillis(), pendingIntent);

或

alarmManager.cancel(pendingIntent);

Answer 2

将Intent，PendingIntent和AlarmManager声明为全局变量

取消预定的

pendingIntent = PendingIntent.getBroadcast(ViewTicketActivity.this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
alarmManager.cancel(pendingIntent);

取消预定的Android通知
