如何让通知保持在最前面？

Question

I have a notification which I always want to stay on top.

I have already given it a priority of 2

Mostly it stays on top but, suppose there is a open WiFi network, then my notification goes down and the notification of open WiFi network comes on the top position.

But when I looked at the notification of vlc(for Android) paying a song, the notification of vlc stay on top and the notification of open WiFi network goes down.

I notification is ongoing and with priority 2.

What should I do. I am a beginner so please bear with me.

And thanks in advance.

Answer 1

have you tried this

NotificationCompat.Builder builder =
            (NotificationCompat.Builder) new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.notify_icon)
            .setContentTitle("Notification")
            .setContentText("ON Top")
            .setPriority(Notification.PRIORITY_MAX);

Priority Levels --> PRIORITY_MAX / PRIORITY_HIGH / PRIORITY_DEFAULT / PRIORITY_LOW / PRIORITY_MIN

Answer 2

I think you can refer to this code:

Intent push = new Intent();
    push.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    push.setClass(this, NotificationDemo.class);
    PendingIntent pi = PendingIntent.getActivity(this, 0, push, PendingIntent.FLAG_CANCEL_CURRENT);

    NotificationManager nm=(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);

    Notification updateNotification = new Notification.Builder(this)
            .setSmallIcon(R.drawable.ic_face_black_24dp)
            .setLargeIcon(BitmapFactory.decodeResource(this.getResources(), R.mipmap.ic_launcher))
            .setContentTitle("Priority Max Notification Title")
            .setContentText("Priority Max Notification Message")
            .setAutoCancel(false)
            .setDefaults(Notification.DEFAULT_SOUND)
            .setPriority(Notification.PRIORITY_MAX)
            .setFullScreenIntent(pi,true)
            .build();



    nm.notify("priorityMaxTest",2,updateNotification);
