If you are using androidX , please refer below code :

  BottomNavigationView mbottomNavigationView =findViewById(R.id.navigation);

        BottomNavigationMenuView mbottomNavigationMenuView =
                (BottomNavigationMenuView) mbottomNavigationView.getChildAt(0);

        View view = mbottomNavigationMenuView.getChildAt(1);

        BottomNavigationItemView itemView = (BottomNavigationItemView) view;

        View cart_badge = LayoutInflater.from(this)
                .inflate(R.layout.notification_badge,
                        mbottomNavigationMenuView, false);

        itemView.addView(cart_badge);
