How i can cancel an alarm after a period of time? | android

问题

hi i have an alarm here and i want a way to cancel it AFTER a period of time like a day for example or a week ,,, and thanks in advance ,,

    am = (AlarmManager)parent.getContext().getSystemService(Context.ALARM_SERVICE);

     //the title and the description of the notification



    Intent alarmintent = new Intent(parent.getContext(), Alarm_Receiver.class);
     alarmintent.putExtra("title",titlePills + dea22);
      alarmintent.putExtra("note",dea22);
     alarmintent.putExtra("NOTIFICATION_ID",String.valueOf(CountMultipleAlarm));
     //HELLO_ID is a static variable that must be initialized at the BEGINNING OF CLASS with 1;

      //example:protected static int HELLO_ID =1;
      PendingIntent sender = PendingIntent.getBroadcast(parent.getContext(), CountMultipleAlarm,
                                     alarmintent,0);

      //VERY IMPORTANT TO SET FLAG_UPDATE_CURRENT... this will send correct extra's informations to 
       //AlarmReceiver Class
         // Get the AlarmManager service
        am.setRepeating(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(), 11000, sender);
                                     intentArray.add(sender);

You have already set an alarm once, so you know how to do it. The key is to set a second alarm, whose purpose is to end the original alarm. The difficult part is finding the original alarm to cancel, however, you can just execute this code upon your second alarm to cancel the first, using the cancel pending intent. This code, as Android docs specify, will cancel all alarms with the same class. Thus, you only need to create an intent, pass it to the AlarmManager, and you can cancel the alarm.

Intent alarmintent = new Intent(parent.getContext(), Alarm_Receiver.class);
PendingIntent sender = PendingIntent.getBroadcast(parent.getContext(), CountMultipleAlarm,
                                 alarmintent,0);
am.cancel(sender);

try

final PendingIntent sender = PendingIntent.getBroadcast(parent.getContext(), CountMultipleAlarm,
                                     alarmintent,0);
int someTime=1000;

new Handler().postDelayed(new Runnable()
{
    public void run()
    {
     am.cancel(sender);
    }
}, someTime);

Set a second alarm that cancels the first alarm.
