Block expanding of Expandable List View on long click

I am developing an android application, in which I am using Expandablelistview to show some data. Currently the list view will expand on both clicking on group and on releasing after long click. But, I need to prevent from expanding the Expandablelistview on long click.

My code segment looks like this:

elvItemList = (ExpandableListView) root.findViewById(R.id.elv_item_list);
elvItemList.setOnGroupClickListener(this);
elvItemList.setAdapter(smListAdapter);
elvItemList.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
    @Override
    public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
        if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
            Utils.logit("SMLOG", "Long button pressed");
            //
        }
        return false;
    }
});

can any one help me?

This works for me.

expandableListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
    @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {

            return true; // Change return false; to return true;
        }
    });

public void stopExpandOnLongClick()
{
    expListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            boolean checkClick=false;
            long packedPosition = expListView.getExpandableListPosition(position);

            int itemType = ExpandableListView.getPackedPositionType(packedPosition);
            int groupPosition = ExpandableListView.getPackedPositionGroup(packedPosition);

             /*  if group item clicked */
            if (itemType == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
                //  ...
                if(expListView.isGroupExpanded(groupPosition))
                {
                    Toast.makeText(MainActivity.this, "It's normal group collaspe", Toast.LENGTH_LONG).show();
                }
                else
                {
                    Toast.makeText(MainActivity.this, "This Grouo is not going to expand on long click", Toast.LENGTH_LONG).show();
                    //you can put your logic when you long press on Group header
                    checkClick=true;
                }
            }
            return checkClick;
        }
    });

ExpandableListView.PACKED_POSITION_TYPE_GROUP is the id of a group, change it to ExpandableListView.PACKED_POSITION_TYPE_CHILD and you can manipulate with longclicks on group childs.

Something like that:

elvItemList.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
// Your code with group long click
return true;
}
return false;
}
});
