Alarm für bestimmte Zeiten in Bezug auf Startdatum und Enddatum eines Ereignisses in Android einstellen

Question

Ich habe ein Kalenderereignis mit Startdatum als (24-Stunden-Format) 27-Apr-2016 11:00:00 und Enddatum als 29-Apr-2016 11:00:00. Ich habe drei Zeitpunkte 10:45:00, 10:30:00 und 10:15:00 die für die Warnung vor den tatsächlichen eingestellten Zeiten (dh 15 Minuten, 30 Minuten und 45 Minuten) berechnet werden Minuten bis zum Startdatum).

Auch der Alarm muss täglich wiederholt werden, bis das Enddatum erreicht ist.

Hier ist, wie ich versuchte, es zu tun, Wie auch immer die folgenden Code nicht den Alarm nicht aufrufen noch wiederholt sie täglich

Im MainActivity.java

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
Intent intent = new Intent(this, Broadcast.class); 
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

Calendar calendar = Calendar.getInstance(); 
calendar.set(2016,03,27,11,00,00); 
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis()-(60000*15), pendingIntent); // subtract for 15 mins prior alarm time 
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis()-(60000*30), pendingIntent); // subtract for 30 mins prior alarm time 
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis()-(60000*45), pendingIntent); // subtract for 45 mins prior alarm time 

Im Sendung. java

Log.i("Alarm", "Alarm Manager is called"); 
Toast.makeText(context, new Date().toString(), Toast.LENGTH_SHORT).show(); 

Wie kann ich das erreichen? Bitte helfen

Hier ist mein Beispielcode ist, versuchen Sie dies:

Ändern Sie das Datum und die Uhrzeit als Ihre Notwendigkeit in den Code unten.

public static int REPEAT_NOTIFICATION1 = 201; 
    public static int REPEAT_NOTIFICATION2 = 202; 
    public static int REPEAT_NOTIFICATION3 = 203; 

    private void repeatNotification() { 
     final DateTime dateTime1 = DateTime.now(); 
     dateTime1.hourOfDay().setCopy(7); 
     dateTime1.minuteOfHour().setCopy(30); 
     dateTime1.secondOfMinute().setCopy(00); 
     final Calendar calendarNotifiedTime1 = Calendar.getInstance(); 
     calendarNotifiedTime1.set(Calendar.HOUR, dateTime1.getHourOfDay()); 
     calendarNotifiedTime1.set(Calendar.MINUTE, dateTime1.getMinuteOfHour()); 
     calendarNotifiedTime1.set(Calendar.SECOND, dateTime1.getSecondOfMinute()); 
     calendarNotifiedTime1.set(Calendar.AM_PM, Calendar.AM); 

     final DateTime dateTime2 = DateTime.now(); 
     dateTime2.hourOfDay().setCopy(12); 
     dateTime2.minuteOfHour().setCopy(30); 
     dateTime2.secondOfMinute().setCopy(00); 
     final Calendar calendarNotifiedTime2 = Calendar.getInstance(); 
     calendarNotifiedTime2.set(Calendar.HOUR, dateTime2.getHourOfDay()); 
     calendarNotifiedTime2.set(Calendar.MINUTE, dateTime2.getMinuteOfHour()); 
     calendarNotifiedTime2.set(Calendar.SECOND, dateTime2.getSecondOfMinute()); 
     calendarNotifiedTime2.set(Calendar.AM_PM, Calendar.PM); 

     final DateTime dateTime3 = DateTime.now(); 
     dateTime3.hourOfDay().setCopy(6); 
     dateTime3.minuteOfHour().setCopy(30); 
     dateTime3.secondOfMinute().setCopy(00); 
     final Calendar calendarNotifiedTime3 = Calendar.getInstance(); 
     calendarNotifiedTime3.set(Calendar.HOUR, dateTime3.getHourOfDay()); 
     calendarNotifiedTime3.set(Calendar.MINUTE, dateTime3.getMinuteOfHour()); 
     calendarNotifiedTime3.set(Calendar.SECOND, dateTime3.getSecondOfMinute()); 
     calendarNotifiedTime3.set(Calendar.AM_PM, Calendar.PM); 


     Intent intent1 = new Intent(EmptyActivity.this, NotificationReceiver.class); 
     intent1.putExtra(NotificationReceiver.NOTIFICATION_MESSAGE, "Repeat " + dateTime1.getHourOfDay() + ":" + dateTime1.getMinuteOfHour() + ":" + dateTime1.getSecondOfMinute()); 
     Intent intent2 = new Intent(EmptyActivity.this, NotificationReceiver.class); 
     intent2.putExtra(NotificationReceiver.NOTIFICATION_MESSAGE, "Repeat " + dateTime2.getHourOfDay() + ":" + dateTime2.getMinuteOfHour() + ":" + dateTime2.getSecondOfMinute()); 
     Intent intent3 = new Intent(EmptyActivity.this, NotificationReceiver.class); 
     intent3.putExtra(NotificationReceiver.NOTIFICATION_MESSAGE, "Repeat " + dateTime3.getHourOfDay() + ":" + dateTime3.getMinuteOfHour() + ":" + dateTime3.getSecondOfMinute()); 
     PendingIntent pendingIntent1 = PendingIntent.getBroadcast(EmptyActivity.this, REPEAT_NOTIFICATION1, intent3, PendingIntent.FLAG_UPDATE_CURRENT); 
     PendingIntent pendingIntent2 = PendingIntent.getBroadcast(EmptyActivity.this, REPEAT_NOTIFICATION2, intent2, PendingIntent.FLAG_UPDATE_CURRENT); 
     PendingIntent pendingIntent3 = PendingIntent.getBroadcast(EmptyActivity.this, REPEAT_NOTIFICATION3, intent3, PendingIntent.FLAG_UPDATE_CURRENT); 
     AlarmManager alarmManager = (AlarmManager) this.getSystemService(ALARM_SERVICE); 


       cancelNotification(REPEAT_NOTIFICATION1); 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendarNotifiedTime1.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent1); 
       cancelNotification(REPEAT_NOTIFICATION2); 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendarNotifiedTime2.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent2); 
       cancelNotification(REPEAT_NOTIFICATION3); 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendarNotifiedTime3.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent3); 
    }
