Adapters

Adapters are bridging classes that bind data to Views (such as List Views) used in the user interface. The adapter is responsible for creating the child Views used to represent each item within the parent View, and providing access to the underlying data. Views that support Adapter binding must extend the AdapterView abstract class.

- ListAdapter: Extended Adapter that is the bridge between a ListView and the data that backs the list. Frequently that data comes from a Cursor, but that is not required. The ListView can display any data provided that it is wrapped in a ListAdapter.

- ArrayAdapter: A listAdapter that manages a ListView backed by an array of arbitrary objects. By default, this class expects  that the provided resource id references a single text view.

- CursorAdapter: Adapter that exposes data from a Cursor to a ListView widget. The Cursor must include a column named "_id" or this class will not work.

- HeaderViewListAdapter: ListAdapter used when a ListView has header views. This ListAdapter wraps another one and also keeps track of the header views and their associated data objects.

- SourceCursorAdapter: It is used to map columns from a cursor to TextViews or ImageViews defined in an XML file. You can specify which columns you want, which views you want to display the columns, and the XML file that defines the appearance of these views

- SimpleAdapter: It is used to to map static data to views defined in an XML file.

- SpinnerAdapter: It  is the bridge between a Spinner and its data. A spinner adapter allows to define two different views: one that shows the data in the spinner itself and one that shows the data in the drop down list when the spinner is pressed.

- WrappedListAdapter: List adapter that wraps another list adapter. The wrapped adapter can be retrieved by calling getWrappedAdapter().
