Android Activity Classes

The Android SDK includes a selection of Activity subclasses that wrap up the use of common user interface widgets. Some of the more useful ones are listed here:

> MapActivity Encapsulates the resource handling required to support a MapView widget within an Activity. Learn more about MapActivity and MapView in Chapter 8.

> ListActivity Wrapper class for Activities that feature a Listview bound to a data source as the primary UI metaphor, and exposing event handlers for list item selection.

> ExpandableListActivity Similar to the List Activity but supporting an ExpandableListView

> TabActivity Enables you to embed multiple Activities or Views within a single screen using a tab widget to switch among them.
