Réglage de l'alarme pour les horaires particuliers en ce qui concerne la date de début et la date de fin d'un événement dans Android

Question

J'ai un événement de calendrier avec Date de début (format 24hrs) 27 avr. 2016 11:00:00 et la date de fin comme 29 avr. 2016 11:00:00. J'ai trois horaires 10:45:00, 10:30:00 et 10:15:00 qui sont calculés pour alerter l'événement avant les horaires réglés (c.-à-d. 15 min, 30 min et 45 min) minutes avant la date de début).

De même, l'alarme doit être répétée tous les jours pour les mêmes horaires antérieurs jusqu'à ce que la date de fin soit atteinte.

Voici comment je l'ai essayé de le faire, comment le code ci-dessous jamais n'invoque pas l'alarme, ni il répète tous les jours

Dans le 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 

Dans la diffusion. Java

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

Comment puis-je y parvenir? S'il vous plaît aider

Voici mon exemple de code, essayez ceci:

Modifier la date et l'heure de votre besoin dans le code ci-dessous.

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); 
    } 

Annuler Notification:

public void cancelNotification(int requestCode) { 
      try { 
       Intent notificationIntent = new Intent(getApplicationContext(), NotificationReceiver.class); 
       PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), requestCode, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
       AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE); 
       alarmManager.cancel(pendingIntent); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 

BroadCast Récepteur:

public class NotificationReceiver extends BroadcastReceiver { 
    public static String NOTIFICATION_MESSAGE = "notificationMessage"; 
    public static int REPEAT_NOTIFICATION1 = 201; 
    public static int REPEAT_NOTIFICATION2 = 202; 
    public static int REPEAT_NOTIFICATION3 = 203; 

    Context context; 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     this.context = context; 

     //Assume StartDate = yesterday. 
     DateTime startDate = DateTime.now().minusDays(1); 
     //Assume EndDate = tomorrow 
     DateTime endDate = startDate.plusDays(2); 

     DateTime today = DateTime.now(); 

     if (today.isBefore(endDate) || today.isEqual(endDate)) { 

      String message = intent.getStringExtra(NOTIFICATION_MESSAGE); 
      NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); 
      //Define sound URI 
      Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 

      Intent notificationIntent = new Intent(context, EmptyActivity.class); 
      notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); 

      PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); 
      final DateTime dateTime = DateTime.now(); 
      int color = 0xffffaa00; 
//  int color1 = context.getColor(R.color.notificatinBackgroundColor); 
      NotificationCompat.Builder builder = new NotificationCompat.Builder(context); 
      builder.setSmallIcon(R.drawable.festi_push_message_small); 
      builder.setContentIntent(pendingIntent); 
      builder.setContentTitle("Notification Sample"); 
      builder.setAutoCancel(true); 
      builder.setContentText(message + ", Current Time : " + dateTime.getHourOfDay() + ":" + dateTime.getMinuteOfHour() + ":" + dateTime.getSecondOfMinute()); 
      builder.setSound(soundUri); 
      builder.setLights(Color.RED, 1000, 1000); 
      builder.setColor(color); 

      Notification notification = builder.build(); 

      notification.flags |= Notification.FLAG_AUTO_CANCEL; 

      notificationManager.notify(102938, notification); 
     } else { 
      cancelNotification(REPEAT_NOTIFICATION1); 
      cancelNotification(REPEAT_NOTIFICATION2); 
      cancelNotification(REPEAT_NOTIFICATION3); 
     } 
    } 

    public void cancelNotification(int requestCode) { 
     try { 
      Intent notificationIntent = new Intent(context, NotificationReceiver.class); 
      PendingIntent pendingIntent = PendingIntent.getBroadcast(context, requestCode, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
      AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 
      alarmManager.cancel(pendingIntent); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

}
