You can use isGroupExpanded .

 expListViewObj.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {

                @Override
                public boolean onGroupClick(ExpandableListView parent, View v,
                                            int groupPosition, long id) {

                    if(parent.isGroupExpanded(groupPosition))
                    {

                     // Do your Staff
                    }
                    else{

                       // Expanded ,Do your Staff

                    }


                    return false;
                }
            });
