712<h2>Class Overview</h2>
713<p itemprop="articleBody">A sadly necessary layer of indirection to interact with AdapterViews.
714 <p>
715 Generally any subclass should respect the contracts and behaviors of its superclass. Otherwise
716 it becomes impossible to work generically with objects that all claim to share a supertype - you
717 need special cases to perform the same operation 'owned' by the supertype for each sub-type. The
718 'is - a' relationship is broken.
719 </p>
720
721 <p>
722 Android breaks the Liskov substitution principal with ExpandableListView - you can't use
723 getAdapter(), getItemAtPosition(), and other methods common to AdapterViews on an
724 ExpandableListView because an ExpandableListView isn't an adapterView - they just share a lot of
725 code.
726 </p>
727
728 <p>
729 This interface exists to work around this wart (which sadly is copied in other projects too) and
730 lets the implementor translate Espresso's needs and manipulations of the AdapterView into calls
731 that make sense for the given subtype and context.
732 </p>
733
734 <p><i>
735 If you have to implement this to talk to widgets your own project defines - I'm sorry.

1208 After calling this method it expected that there will exist some descendant view of adapterView
1209 for which calling getDataRenderedByView(adapterView, descView).get() == data.data is true.

1213 Note: this need not happen immediately. EG: an implementor handling ListView may call
1214 listView.smoothScrollToPosition(data.opaqueToken) - which kicks off an animated scroll over
1215 the list to the given position. The animation may be in progress after this call returns. The
1216 only guarantee is that eventually - with no further interaction necessary - this data item
1217 will be rendered as a child or deeper descendant of this AdapterView.
