ExpandableListView in Scrollview

expandablelistview_oncreate.java

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

    ExpandableAdapter adapter = new ExpandableAdapter();
    expandableListView.setAdapter(adapter);
    setExpandableListViewHeight(expandableListView, -1);
    expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int position, long id) {
            setExpandableListViewHeight(parent, position);
            return false;
        }
    });
    return view;
}

I used this method on my extendedListView but at first unnecessary extra space remains in my activity. Then I clicked a group, and it fixed. How to fix this problem?

I solved it. You can use it.
