SimpleExpandableListAdapter
public
class
SimpleExpandableListAdapter
extends BaseExpandableListAdapter
An easy adapter to map static data to group and child views defined in an XML
file. You can separately specify the data backing the group as a List of
Maps. Each entry in the ArrayList corresponds to one group in the expandable
list. The Maps contain the data for each row. You also specify an XML file
that defines the views used to display a group, and a mapping from keys in
the Map to specific views. This process is similar for a child, except it is
one-level deeper so the data backing is specified as a List>,
where the first List corresponds to the group of the child, the second List
corresponds to the position of the child within the group, and finally the
Map holds the data for that particular child.
