Android设置具有唯一ID的闹钟

在我的应用程序中，我使用多个警报管理器，并且它们都工作正常。现在，我的应用程序还需要两件事：

• 为每个alarmManager设置一个ID，以便我可以在广播接收器中识别此警报

• 使用此ID稍后取消警报

我设置警报的代码

    Calendar cal1 = Calendar.getInstance();
    cal1.set(Calendar.HOUR_OF_DAY, h1);
    cal1.set(Calendar.MINUTE, m1+30);
    cal1.set(Calendar.SECOND, 00);

    Intent intent = new Intent(context, YourBroadCastReceiver.class);


    // Add Some unique ID here for e.g "SFSF43535"
    PendingIntent openAlarm = PendingIntent.getBroadcast(context, 0, intent, 0);
     // Add Some unique ID here for e.g "SFSf87sfs"
    PendingIntent CloseAlarm = PendingIntent.getBroadcast(context, 0, intent, 0);

    AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                      cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, openAlarm);

   alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                      cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, CloseAlarm);

YourBroadCastReceiver（在此我需要该唯一ID）

  @Override
    public void onReceive(Context context, Intent intent) {
       // Get Unique id here to find some data related to that alram 
    }
