Remarks
An adapter that exposes data from a series of Cursors to an ExpandableListView widget. The top-level Cursor (that is given in the constructor) exposes the groups, while subsequent Cursors returned from #getChildrenCursor(Cursor) expose children within a particular group. The Cursors must include a column named "_id" or this class will not work.

Properties
| Name | Description |
|---|---|
| ChildTypeCount |
Returns the number of types of child Views that will be created by android.widget.ExpandableListAdapter.getChildView(int,int,boolean,View,ViewGroup) . Each type represents a set of views that can be converted in android.widget.ExpandableListAdapter.getChildView(int,int,boolean,View,ViewGroup) , for any group. If the adapter always returns the same type of View for all child items, this method should return 1. This method will only be called when the adapter is set on the AdapterView . Returns the number of types of child Views that will be created by android.widget.ExpandableListAdapter.getChildView(int,int,boolean,View,ViewGroup) . Each type represents a set of views that can be converted in android.widget.ExpandableListAdapter.getChildView(int,int,boolean,View,ViewGroup) , for any group. If the adapter always returns the same type of View for all child items, this method should return 1. (Inherited from BaseExpandableListAdapter) |
