android - 从另一个 Fragment 取消在一个 Fragment 中设置的警报和通知

Question

我正在尝试从另一个 Fragment 取消 Fragment 中设置的闹钟，我该怎么做？

InserisciOra.java(我在其中设置闹钟的 fragment )

Intent myIntent = new Intent(getActivity(), MyReceiver.class);
if(PendingIntent.getBroadcast(getActivity(), 0, 
    myIntent, 
    PendingIntent.FLAG_NO_CREATE) == null){

        pendingIntent = PendingIntent.getBroadcast(getActivity(), 0, myIntent,0);
        alarmManager = (AlarmManager)getActivity().getSystemService(Context.ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

Answer 1

      Intent myIntent = new Intent(getActivity(), MyReceiver.class);
      pendingIntent = PendingIntent.getBroadcast(getActivity(), 0, myIntent,0);
      alarmManager = (AlarmManager)getActivity().getSystemService(Context.ALARM_SERVICE);
      // cancel the alarm
      alarmManager.cancel(pendingIntent);
      // delete the PendingIntent
      pendingIntent.cancel()
