ExpandableListView - empty group message

I am developing an app which has an ExpandableListActivity. When a group has no children, I would like it to show a message, as if it was a child, informing that the list is empty, as shown in the picture:

Is there any (reasonably simple) way to do this, or something similar?

I am sorry if this has been asked before - I kind of assume it must have been, but I haven't been able to find anything. Thank you!

EDIT: To clarify, what I'm looking for is not an empty view for the complete ExpandableListView (which can be set with setEmptyView), but for parent groups with no children.

My experience with this particular class isn't that great, but I would suggest trying to override the Adapter's getChildrenCount method to return 1 when there aren't any child records.

Then, in the Adapter's getChildView method, if you cannot find any child for the specified parent, return a custom view containing your message.

correct me if i am wrong but you can use method setEmpty() to inform a list to be empty. Assuming you have a custom expandable list view in xml with id of android:list and another text view with id of android:empty. In code, you just need to have list.setEmpty(empty_text_view);
