I'm developing android application using expandable list view. Actually what I need is, I'm listing group, which contains child.
If I select an unexpandable group, it should expand, after I ll select second group at that time the first group should be collapsed. I did Google, but I couldn't find what I want. Please help me out.
Have the current expanded group position stored in a variable. In onGroupExpanded do the following.
private int lastExpandedPosition = -1;
private ExpandableListView lv; //your expandable listview
...
lv.setOnGroupExpandListener(new OnGroupExpandListener() {
@Override
public void onGroupExpand(int groupPosition) {
if (lastExpandedPosition != -1
&& groupPosition != lastExpandedPosition) {
lv.collapseGroup(lastExpandedPosition);
}
lastExpandedPosition = groupPosition;
}
});
