Android Navigation View set menu programmatically
Use inflateMenu
on your NavigationView
.
For example:
navigationView.getMenu().clear();
navigationView.inflateMenu(R.menu.menu_view);
See here for more information.
This should work:
val menu = navigationView.menu
val submenu = menu.addSubMenu("New set")
submenu.add("Item1")
submenu.getItem(0).setIcon(R.drawable.item1)
submenu.add("Item2")
submenu.getItem(1).setIcon(R.drawable.item2)
submenu.add("Item3")
submenu.getItem(2).setIcon(R.drawable.item3)
navigationView.invalidate()
Hope it helps.
navigationView.getMenu().clear();
navigationView.inflateMenu(R.menu.your_menu);
