爲選定的數據和時間設置鬧鐘

Question

我用picker類完成了我的代碼。 我想在日期和時間選擇器選擇的時間運行鬧鐘。 我不知道我需要編碼哪些類和方法才能在此選定時間內運行警報。

@Override 
      public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 

       Calendar calNow = Calendar.getInstance(); 
       Calendar calSet = (Calendar) calNow.clone(); 

       calSet.set(Calendar.HOUR_OF_DAY, hourOfDay); 
       calSet.set(Calendar.MINUTE, minute); 
       calSet.set(Calendar.SECOND, 0); 
       calSet.set(Calendar.MILLISECOND, 0); 

       if(calSet.compareTo(calNow) <= 0){ 
        //Today Set time passed, count to tomorrow 
        calSet.add(Calendar.DATE, 1); 
       } 

       setAlarm(calSet); 
      }}; 

     private void setAlarm(Calendar targetCal){ 

      textAlarmPrompt.setText(
        "\n\n***\n" 
        + "Alarm is set@ " + targetCal.getTime() + "\n" 
        + "***\n"); 

      Intent intent = new Intent(getBaseContext(), AlarmReceiver.class); 
      PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0); 
      AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE); 
    //  alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent); 
      alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pendingIntent); 
     }
