Expandable ListView get group child count - onClick

I am using an expandable listview in Navigation Drawer. Now the items in this list are fetched from a webservice - along with the children.

Based on the login type some users only see part of the Navigation drawer. So I have some items with 0 children and I need to detect this condition so that I can redirect on header click to a different page.

Here is my scenario:

I want to get the number of children in a group when the header is clicked. Is this even possible?

So far I have tried this, but the result are not proper: 

 @Override
    public void onDrawerHeaderSelected(ExpandableListView parent, View v, int groupPosition, long id) {

        switch (groupPosition) {
            case 1:
                if (parent.getChildCount() == 0)
                    displayFragment(groupPosition);
                break;
            case 2:
                if (parent.getChildCount() == 0)
                    displayFragment(groupPosition);
                break;
            default:
                displayFragment(groupPosition);
        }


    }

parent.getChildCount() seems to give me a total nmber of visible children.

Use setOnGroupClickListener and in onGroupClick check your condition using the list of data that you already have and display fragment and return true.

To find group child count - adapter.getChildrenCount(groupPosition)

use the Adapter.

ExpandableListAdapter adapter = parent.getExpandableListAdapter()

and trough adapter you can access getChildrenCount and getGroupCount()
