Android :: In An ExpandableListView - Show One Additional Line At The End Of The Child Results?

I have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work.

If a group has three children what I have working looks like this:

Group
NormalChild
NormalChild
NormalChild

But I'd really like something like this:

Group
NormalChild
NormalChild
NormalChild
AlternateChild

The idea being that the AlternateChild could be a link to more info about the group.

ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible
