Adding icon with submenu items

Question

I have made submenu with some items in it. Now I want to add different icon with submenu items. I have also applied the code to the menu items for adding icon but it is not showing me icons my code is this:

public boolean onCreateOptionsMEnu(Menu m) {
    SubMenu s1 = m.addSubMenu("menu1");
    s1.add(0,0,1,"1").setIcon(R.drawable.icon1);
    s1.add(0,1,2,"2").setIcon(R.drawable.icon2);

    return super.onCreateOptionsMenu(m);
}

Answer 1

Submenus don't support icons.

https://developer.android.com/guide/topics/ui/menus.html:

Icon Menu
This is the collection of items initially visible at the bottom of the screen at the press of the MENU key. It supports a maximum of six menu items. THESE ARE the only menu items that support icons and the only menu items that do not support checkboxes or radio buttons.
