- adapter
- An adapter that will provide views both to display the current navigation selection and populate views within the dropdown navigation menu.
- callback
- An OnNavigationListener that will receive events when the user selects a navigation item.

(These may be displayed differently.) The supplied OnNavigationListener will alert the application when the user changes the current list selection.
