Android’de NotificationManager Kullanarak Bildirim Oluşturma

Download

Merhaba arkadaşlar bu konuda android’de NotificationManager kütüphanesini kullanarak bildirim oluşturacağız. Telefonun ekranına bildirim düşüreceğiz. Aşağıda metodlarımız ve tüm kodlarımızı paylaşacağız isterseniz konun altından gerekli dosyalarıda indirebilirsiniz.

Projede 4 adet metod tanımlanmış ve bunlar mainactivity dosyası içerisinde bulunmaktadır.

  • displayNotification();
  • cancelNotification();
  • updateNotification();
  • displayInBoxNotification();

Metotlara ait kodlara aşağıdan göz atabilirsiniz.

displayNotification()cancelNotification()updateNotification()displayInBoxNotification()

Bu metot ile bildirim ekranı için.

@SuppressLint("NewApi")
  void displayNotification() {
    NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(
        this);
    nBuilder.setContentTitle("Notification");
    nBuilder.setContentText("You have received a new Notification");
    nBuilder.setTicker("New Message");
    nBuilder.setAutoCancel(true);
    nBuilder.setSmallIcon(R.drawable.ic_tag_logo);
    nBuilder.setNumber(++totalMessages);

    Intent intent = new Intent(this, NotificationClass.class);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    stackBuilder.addParentStack(NotificationClass.class);

    stackBuilder.addNextIntent(intent);

    PendingIntent pendingIntent = stackBuilder.getPendingIntent(0,
        PendingIntent.FLAG_UPDATE_CURRENT);
    nBuilder.setContentIntent(pendingIntent);

    mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(notificationID, nBuilder.build());
  }

Bu metot bildirimi iptal etmek için.

void cancelNotification() {
  if (mNotificationManager != null) {
    mNotificationManager.cancel(notificationID);
  }
}

Bildirimi güncellemek isterseniz diye kullanabileceğiniz metot

@SuppressLint("NewApi")
void updateNotification() {
  NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
      this);
  mBuilder.setContentTitle("Updated Notification");
  mBuilder.setContentText("You've got updated Notification.");
  mBuilder.setTicker("Updated Notification Alert!");
  mBuilder.setAutoCancel(true);
  mBuilder.setSmallIcon(R.drawable.ic_tag_logo);

  mBuilder.setNumber(++totalMessages);
  Intent resultIntent = new Intent(this, NotificationClass.class);

  TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
  stackBuilder.addParentStack(NotificationClass.class);

  stackBuilder.addNextIntent(resultIntent);
  PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
      PendingIntent.FLAG_UPDATE_CURRENT);

  mBuilder.setContentIntent(resultPendingIntent);
  mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  mNotificationManager.notify(notificationID, mBuilder.build());
}

Bildirim ekranı tasarımı için metot.

void displayInBoxNotification() {
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
        this);

    mBuilder.setContentTitle("New Message");
    mBuilder.setContentText("You've received new message.");
    mBuilder.setTicker("New Message Alert!");
    mBuilder.setAutoCancel(true);
    mBuilder.setSmallIcon(R.drawable.ic_tag_logo);
    mBuilder.setNumber(++totalMessages);

    NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

    String[] notificationArray = new String[6];
    notificationArray[0] = new String("First Notification...");
    notificationArray[1] = new String("Second Notification...");
    notificationArray[2] = new String("Third Notification ....");
    notificationArray[3] = new String("Fourth Notification.....");
    notificationArray[4] = new String("Fifth Notification....");
    notificationArray[5] = new String("Sixth Notification....");

    inboxStyle.setBigContentTitle("Notification Details.");

    for (int i = 0; i < notificationArray.length; i++) {
      inboxStyle.addLine(notificationArray[i]);
    }
    mBuilder.setStyle(inboxStyle);

    Intent resultIntent = new Intent(this, NotificationClass.class);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    stackBuilder.addParentStack(NotificationClass.class);

    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
        PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.setContentIntent(resultPendingIntent);
    mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(notificationID, mBuilder.build());
  }
