Change Background Color of Clicked Child in Expandable ListView Android

Question

I want to change the background color of the child which is clicked in an ExpandableListView. That is, when any child is clicked, it\'s background color should get changed.

Answer 1

This is how I solved it.

View _lastColored;
public boolean onChildClick(ExpandableListView parent, View v,
        int groupPosition, int childPosition, long id) {
    _groupPosition = groupPosition;


    if(_lastColored != null)
    {
    _lastColored.setBackgroundColor(Color.TRANSPARENT);
    _lastColored.invalidate();
    }
    _lastColored = v;
    v.setBackgroundColor(Color.rgb(214, 214, 214));


    return false;
}
