android.widget.HeterogeneousExpandableList |
Known Indirect Subclasses |
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 ExpandableListView
s,
these values should be tuned for heterogeneous ExpandableListView
s.
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.
