Right now I am trying to implement the DrawerLayout/NavigationView from the new Design Support libary (22.2.1) into my application. I already searched on the internet and especially on stackoverflow how to add a MenuItem to a Submenu with Icon and Title. I know that it is possible to add a menuitem with a title or icon.
like that:
Menu m = mNavigationView.getMenu();
m.add(R.id.groupID,R.id.menuItemID,orderNumber,"title");
But that is only a MenuItem with a Title,without Icon. Is it possible to add a MenuItem with a Title and Icon?
First get the Menu from the NavigationView:
Menu menu = mNavigationView.getMenu();
Then add your item to the menu, remember to get the return MenuItem so you can add the icon later:
MenuItem item = menu.add(groupId, menuItemId, Order, "Menu Item 1 Title");
item.setIcon(R.drawable.ic_some_menu_item_icon); // add icon with drawable resource
