Create a layout with one Textview like below.

After initializing the BottomNavgationView, you have to inflate the layout and select the index of View item and set the count.

    BottomNavigationMenuView bottomNavigationMenuView =
            (BottomNavigationMenuView) bottomNavigationView.getChildAt(0);
    View v = bottomNavigationMenuView.getChildAt(1);
    BottomNavigationItemView itemView = (BottomNavigationItemView) v;

    View badge = LayoutInflater.from(this)
            .inflate(R.layout.homescreen_count, bottomNavigationMenuView, false);
    TextView tv = badge.findViewById(R.id.notification_badge);
