android - Sub Menu in App

Question

Is having a sub menu possible in Android?

And what do you call this view in Android?

Answer 1

As others have mentioned, this is an ExpandableListView, within a NavigationDrawer. There are several tutorials you can use (see my list below).

One piece of advice based on personal experience: the baseline behavior for the SimpleExpandableListAdapter is pretty limiting and often not what you're looking for in your customization. If you're looking to have your own specific behavior and look-and-feel to the sub menus, I highly recommend looking into extending the BaseExpandableListAdapter yourself and creating your own custom adapter. [This may seem daunting at first, but it's not terribly hard once you have a grasp on your parents and children within your menu and sub menu(s).]
