推荐答案

这是如何实现的警报经理。但你需要了解Android中也Calendar对象。

This is how you implement an alarm manager. But you will need to read about Calendar object in android also.

 String alarm = Context.ALARM_SERVICE;
 Calendar calendar = Calendar.getInstance();

 calendar.set(Calendar.HOUR_OF_DAY, 8);//Just an example setting the alarm for the 8th hour of a day.
  calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND,0);
calendar.set(Calendar.MILLISECOND, 0);



AlarmManager am = (AlarmManager)getActivity().getSystemService(alarm);
//This is the intent that is launched when the alarm goes off.
                    Intent intent = new Intent("WAKE_UP");

PendingIntent sender = PendingIntent.getBroadcast(getActivity(), 0, intent, 0);



//If the user wants the alarm to repeat then use AlarmManager.setRepeating if they just want it one time use AlarmManager.set().

    am.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis() , AlarmManager.INTERVAL_DAY, sender);




                    }

此外，你需要注册一个广播接收到报警时设置它关闭，除了意图。
创建广播reciever并在清单注册它来接收从报警的意图。
