How to cast MenuItem to LinearLayout

Question

I have NavigationView with menus. I am able to get MenuItem from navigationView by using

MenuItem menuItem = navigatio         


        

Answer 1

Try this first set custom layout to your MenuItem than cast it to LinearLayout like below code

MenuItem item = menu.findItem(R.id.action_cart);
MenuItemCompat.setActionView(item, R.layout.menu_layout);
LinearLayout linearLayout = (LinearLayout) MenuItemCompat.getActionView(item);

EDIT

setActionView() and getActionView() method was deprecated in API level 26.1.0.

Direct use MenuItem.setActionView() and MenuItem.getActionView()

SAMPLE CODE

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuItem item = menu.findItem(R.id.action_menu);
        item.setActionView( R.layout.activity_main);
        LinearLayout linearLayout = (LinearLayout) item.getActionView();
        return super.onCreateOptionsMenu(menu);
    }
