how to get group having no child in ExpandableListView

I am using Custom ExpandableListview for first time. I have custom expandable listview which contains 10 groups in which some groups have child and some groups don't have child.

I want child when the child item is clicked. (in case of groups having child)

I want group when the group item is clicked. (in case of groups don't have child)

I am getting child by using OnChildClickListener(first case) , but I didn't getting group. (second case)

Is there any way to get both at a time. If group have child then return clicked child otherwise return clicked group.

Please help me

You can use this method to get the index of parent view, and check whether the parent in that position contains a child or not.

expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {

    @Override
    public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
        //here you can check whether your parent contains a child or not by getting the parent position.
        return false;
    }
});

First set OnChildClickListener to list

Next set OnGroupExpandListener to list

exList.setOnChildClickListener(this);
exList.setOnGroupExpandListener(this);

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
    Group gr = ds_list.get(groupPosition);
    //here you can get child from group
    return true;
}

@Override
public void onGroupExpand(int i) {
    if(group don't have child) {
        //get group by using group position(i)
    }
}

You can add OnGroupCollapseListener also

Don't use OnChildClickListener and OnGroupExpandListener together because group items are not expandable behaves like a normal ListView
