Navigation in a mobile application is controlled by a stack of View objects. The top View object on the stack defines the currently visible view. The ViewNavigator container maintains the stack. To change views, push a new View object onto the stack, or pop the current View object off of the stack. Popping the currently visible View object from the stack destroys the View object, and returns the user to the previous view on the stack.
When a view is pushed on top of the stack, the old view's data
property is automatically persisted.
It is restored when the view is reactived as a result of
the current view being popped off the stack.
When a new view becomes active by being pushed onto the stack,
the old view's instance is destroyed.
The ViewNavigator displays an optional ActionBar control that displays contextual information defined by the active view. When the active view changes, the action bar is automatically updated.
