android - 停止Android alarmmanager的setrepeat

Question

我已经创建了如下所示的警报

Intent intent = new Intent(this, Areceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(this, 1234567, intent, 0);

AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, timenow, 3000, sender);

我创建了一个按钮来停止警报。在 onclick 方法中，我编写了以下代码

Intent intentstop = new Intent(this, Areceiver.class);
PendingIntent senderstop = PendingIntent.getBroadcast(this,
            0, intentstop, 0);
AlarmManager alarmManagerstop = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManagerstop.cancel(senderstop);

但工作并没有停止。可能是什么问题？

Answer 1

You gave your Pending intent a request_code = 1234567 when you start the alarm. But you are using 0 when you try to stop it. Use this when trying to stop and should work

Intent intentstop = new Intent(this, Areceiver.class);
PendingIntent senderstop = PendingIntent.getBroadcast(this,
            1234567, intentstop, 0);
AlarmManager alarmManagerstop = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManagerstop.cancel(senderstop);
