Implementing an expandable listview in tab fragment

1) Call findViewById() on the View returned
findViewById in Fragment

2) Change the first argument in the ExpandableListAdapter from 'this' to 'getActivity()'

My new onCreateView looks like this:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) 
{
    View view = inflater.inflate(R.layout.tab_expandable_list, container, false);

    // get the listview
    expListView = (ExpandableListView) view.findViewById(R.id.lvExp);

    // preparing list data
    prepareListData();

    listAdapter = new ExpandableListAdapter(getActivity(), listDataHeader, listDataChild);

    // setting list adapter
    expListView.setAdapter(listAdapter);

    return view;
}

ExpandableListview - How do I close the previous opened item, when another item is clicked?

So you need only one (or zero) expanded group at a time. Right? The following code will close the previously expanded group when you expand another one. Try it.

Here you go

final int[] prevExpandPosition = {-1};
    expandableListView.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
        @Override
        public void onGroupExpand(int groupPosition) {
            if (prevExpandPosition[0] >= 0 && prevExpandPosition[0] != groupPosition) {
                expandableListView.collapseGroup(prevExpandPosition[0]);
            }
            prevExpandPosition[0] = groupPosition;
        }
    });
