HeterogeneousExpandableList

public interface HeterogeneousExpandableList

android.widget.HeterogeneousExpandableList

Known Indirect Subclasses BaseExpandableListAdapter, CursorTreeAdapter, ResourceCursorTreeAdapter, SimpleCursorTreeAdapter, SimpleExpandableListAdapter BaseExpandableListAdapter Base class for a ExpandableListAdapter used to provide data and Views from some data to an expandable list view.  CursorTreeAdapter An adapter that exposes data from a series of Cursors to an ExpandableListView widget.  ResourceCursorTreeAdapter A fairly simple ExpandableListAdapter that creates views defined in an XML file.  SimpleCursorTreeAdapter An easy adapter to map columns from a cursor to TextViews or ImageViews defined in an XML file.  SimpleExpandableListAdapter An easy adapter to map static data to group and child views defined in an XML file.

Additional methods that when implemented make an ExpandableListAdapter take advantage of the Adapter view type mechanism.

An ExpandableListAdapter declares it has one view type for its group items and one view type for its child items. Although adapted for most ExpandableListViews, these values should be tuned for heterogeneous ExpandableListViews.

Lists that contain different types of group and/or child item views, should use an adapter that implements this interface. This way, the recycled views that will be provided to getGroupView(int, boolean, View, ViewGroup) and getChildView(int, int, boolean, View, ViewGroup) will be of the appropriate group or child type, resulting in a more efficient reuse of the previously created views.
