Spinner as one of the items for a child of ExpandableListView

Question

There is a expandable List View with Spinner as one of the items for each Child. The issue is the content of parent getting affected on select of item from the spinner. And also on selection of item from any spinner IS affecting the selected items of other spinners of all the groups.

Along with Spinner there are TextView, EditText, CheckBox. Behavior of all the views except Spinner is appropriate as expected.

Use notifyDataSetChanged() in the Event Handler of the Spinner within the Adapter class can resolve to some extent. Still searching for a absolute solution
