觸發在指定的日期和時間報警

Question

我有報警和通知，他們都工作正常，但我需要觸發哪些用戶和天，這是恆定的輸入在特定時間報警：

1.tonight在timepicker時間 2.tomorrow在 3.3天后來在 4.14天后來在 5.30天后來在 6.90天后來在timepicker時間

這裏timepicker時間timepicker時間timepicker時間timepicker時間是我的代碼：

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
      TimePicker timePicker1; 
      timePicker1 = (TimePicker) findViewById(R.id.timePicker1); 
      // ---get current date and time--- 
      Calendar calendar = Calendar.getInstance(); 


      // ---PendingIntent to launch activity when the alarm 
      // triggers--- 
      Intent intent = new Intent(List2.this, 
        DisplayNotifications.class); 
      intent.putExtra("message", esmdars); 
      intent.putExtra("Title", "alarm"); 
      PendingIntent pendingIntent = PendingIntent.getBroadcast(
        List2.this, 0, intent, 0); 

      // ---sets the alarm to trigger--- 

      alarmManager.set(
        AlarmManager.RTC_WAKEUP, 
        System.currentTimeMillis() 
          + (TimeUnit.SECONDS.toMillis(30)), 
        pendingIntent); 

報警本節觸發並顯示例如通知這裏30秒後啓動：

alarmManager.set(
        AlarmManager.RTC_WAKEUP, 
        System.currentTimeMillis() 
          + (TimeUnit.SECONDS.toMillis(30)), 
        pendingIntent); 

我怎樣才能在天，在這一天中的特定時間被激活？

Answer 1

試試這個：

Calendar calendar = Calendar.getInstance(); 
calendar.setTimeInMillis(System.currentTimeMillis()); 
calendar.set(Calendar.HOUR_OF_DAY, hour); 
calendar.set(Calendar.MINUTE, minutes); 
calendar.set(Calendar.DAY_OF_MONTH, day_of_month); 
calendar.set(Calendar.MONTH, month); 
calendar.set(Calendar.YEAR, year); 
alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
