You can convert simple notification to full screen notification just added a simple line of code builder.setFullScreenIntent(pendingIntent, true); following is full example. I hope this code help you

Full Screen Notification Code:

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setSmallIcon(android.R.drawable.btn_star);
        builder.setContentTitle("This is title of notification");
        builder.setContentText("This is a notification Text");
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));

        Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);

        builder.setContentIntent(pendingIntent);
        builder.setAutoCancel(true);

        builder.setFullScreenIntent(pendingIntent, true);


        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(115, builder.build());
