Answer 1

You surely should't add Child radio group from xml.. try adding it at run time... then just keep all

those children in a Some key value pair (Child position as key and RadioButton Object).. Now you don't

need uniqueness since You have reference to all RadioButtons.. I had same issue and I did this, now it

works great.. it becomes easy for handling these since you always get childPosition in

ExpandibleListView thus making it easy to access..
