BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
for (int i = 0; i < menuView.getChildCount(); i++) {
BottomNavigationItemView itemView = (BottomNavigationItemView) menuView.getChildAt(i);

itemView.setVisibility(visibility);
}
}
}` i am getting error cannot resolve BottomNavigationItemView
