Try this snippet - Hope it'll solve your problem.

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID);

//building some actions...

builder.setSmallIcon(R.mipmap.ic_launcher_round)
                .setStyle(new android.support.v4.media.app.NotificationCompat.MediaStyle()
                        .setShowActionsInCompactView(0, 1, 2)
                        .setShowCancelButton(true)
                        .setMediaSession(mediaSessionCompat.getSessionToken()))
                .setCategory(NotificationCompat.CATEGORY_TRANSPORT)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setShowWhen(false)
                .setContentTitle("Title Name")
                .setContentText("Content text")
