如何取消AlarmManager在预定的时间 [英] How to Cancel AlarmManager on a Scheduled time

问题描述

我怎么能删除一个AlarmManager在预定的时间，这是已经开始了。我入手一部AlarmManager这样。

我要5小时后取消。我怎样才能做到这一点？

  AlarmManager服务=（AlarmManager）context.getSystemService（Context.ALARM_SERVICE）;
意图I =新的意图（背景下，MyStartServiceReceiver.class）;
PendingIntent未决= PendingIntent.getBroadcast（背景下，0，I，PendingIntent.FLAG_CANCEL_CURRENT）;
日历CAL = Calendar.getInstance（）;
cal.add（Calendar.SECOND，30）;
service.setInexactRepeating（AlarmManager.RTC_WAKEUP，cal.getTimeInMillis（），REPEAT_TIME，待定）;
 

解决方案

设置其他报警5小时从现在开始。当这种报警器报警熄灭然后取消第一时间报警。

  AlarmManager服务=（AlarmManager）context.getSystemService（Context.ALARM_SERVICE）;
意图int​​entForCancelling =新的意图（背景下，ReceiverForCancelling.class）;
PendingIntent未决= PendingIntent.getBroadcast（上下文，0，intentForCancelling，
PendingIntent.FLAG_CANCEL_CURRENT）;
日历CAL = Calendar.getInstance（）;
cal.roll（Calendar.HOUR_OF_DAY，5）;
service.set（AlarmManager.RTC_WAKEUP，
cal.getTimeInMillis（），申请中）
 

和，从 ReceiverForCancelling 则可以取消第一个报警。
:

  AlarmManager服务=（AlarmManager）context.getSystemService（Context.ALARM_SERVICE）;
意向意图=新的意图（背景下，ReceiverForCancelling.class）;
PendingIntent未决= PendingIntent.getBroadcast（背景下，0，意图，
PendingIntent.FLAG_CANCEL_CURRENT）;
service.cancel（待定）;
 

How can I cancel one AlarmManager on a scheduled time, which was already started. I am starting one AlarmManager like this.

I want to cancel it after 5 hours. How can I do this?

AlarmManager service = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, MyStartServiceReceiver.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, i, PendingIntent.FLAG_CANCEL_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 30);
service.setInexactRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), REPEAT_TIME, pending);

解决方案

set a another alarm for 5 hours from now. when this alarm alarm goes off then cancel the first alarm.

AlarmManager service = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intentForCancelling = new Intent(context, ReceiverForCancelling.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, intentForCancelling,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar cal = Calendar.getInstance();
cal.roll(Calendar.HOUR_OF_DAY, 5);
service.set(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), pending)

and, from ReceiverForCancelling you can cancel the first alarm.
edit::

AlarmManager service = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, ReceiverForCancelling.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
service.cancel(pending);
