How to add click event on expandablelistview group which has no child

Question

In my expandablelistview some have children and some doesn't. GroupView's which have no children contain a Textview and a Button. On clicking the button, i need to pass the textview's data to next activity through intent. Now my problem is, i can't able to set the onclick event on groupview's button which has no child and i also need the groupPosition.

Here is my clickListener code in main java file:

expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
            switch (groupPosition) {
                case 0:
                    Log.d(">>>", "" + groupPosition);
                    break;
                case 1:
                    Log.d(">>>", "" + groupPosition);
                    break;
                case 2:
                    Log.d(">>>", "" + groupPosition);
                    break;
                case 3:
                    Log.d(">>>", "" + groupPosition);
                    break;
            }
            return false;
        }
    });

Here is my adapter code:

public View getGroupView(int groupPosition, boolean isExpanded,
                         View convertView, ViewGroup parent) {
    groupIndex = groupPosition;
    QuotedListGroup group = (QuotedListGroup) getGroup(groupPosition);
    if (convertView == null) {
        LayoutInflater inf = (LayoutInflater) context
                .getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = inf.inflate(R.layout.activity_expandable_listview, null);
    }

    if(groupPosition%2 == 0) {
        convertView.findViewById(R.id.part_1).setVisibility(View.VISIBLE);
        convertView.findViewById(R.id.part_2).setVisibility(View.GONE);
        //Other code..
    } else {
        convertView.findViewById(R.id.part_1).setVisibility(View.GONE);
        convertView.findViewById(R.id.part_2).setVisibility(View.VISIBLE);
        //Other code..
    }
    return convertView;
}

Actually, i need to show two different layouts for even numbered and odd numbered groups in the same expandablelistview.

Any help you can provide is greatly appreciated!

isn't that `getGroupView()` code enough? Other than that, i don't have my project specific code much in my adapter @Pravin — Mr.7, May 05 '16 at 13:30
I think this post is the same as to your other one that I answered. — AL., May 10 '16 at 03:33

like this

elv.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {

            Bundle bundle;
            switch (groupPosition) {
               case 0:
               //add your code here

            return false;
        }
    });

use ExpandableListView.OnGroupClickListener() it will also give you the group position.
