Remarks
Base class for a ExpandableListAdapter used to provide data and Views from some data to an expandable list view.
Adapters inheriting this class should verify that the base implementations of #getCombinedChildId(long, long) and #getCombinedGroupId(long) are correct in generating unique IDs from the group/children IDs.

Constructors
| Name | Description |
|---|---|
| BaseExpandableListAdapter() |
Provides the managed binding for |
| BaseExpandableListAdapter(IntPtr, JniHandleOwnership) |
A constructor used when creating managed representations of JNI objects; called by the runtime. |
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. |
| Class |
Returns the runtime class of this |
| GroupCount |
Gets the group count. |
| GroupTypeCount |
Returns the number of types of group Views that will be created by android.widget.ExpandableListAdapter.getGroupView(int,boolean,View,ViewGroup) . Each type represents a set of views that can be converted in android.widget.ExpandableListAdapter.getGroupView(int,boolean,View,ViewGroup) . If the adapter always returns the same type of View for all group 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 group Views that will be created by android.widget.ExpandableListAdapter.getGroupView(int,boolean,View,ViewGroup) . Each type represents a set of views that can be converted in android.widget.ExpandableListAdapter.getGroupView(int,boolean,View,ViewGroup) . If the adapter always returns the same type of View for all group items, this method should return 1. |
