Sort expandable listview

I want to sort an expendable listview dynamically. Could someone tell me how to accomplish this?

I've trie开发者_如何学编程d sorting the group name but then the child elements don't get sorted.

I think we would need more details about the code, without the code it's hard to tell but anyway here is a link to some code maybe it will help you: https://github.com/commonsguy/cwac-touchlist

Basically what I did was sort it using custom comparator methods.
