 SimpleExpandableListAdapter expListAdapter =

            new SimpleExpandableListAdapter(

                    this,

                    

                    createGroupList(),              // Creating group List.

                    R.layout.group_row,  

                  // Group item layout XML.

                    new String[] { "OrderInfo","CustomerInfo"},  // the key of group item.

                    new int[] { R.id.order,R.id.customer},

                    

                    // ID of each group item.-Data under the key goes into this TextView.

                    createChildList(),              // childData describes second-level entries.

                    R.layout.single_list_item,  

                

                   new String[] {"KEY_ARTIST","KEY_DURATION","KEY_SUBTOTAL","KEY_DISCOUNT","KEY_COUPON","KEY_COST"},  

                   new int[] { R.id.payment_label,R.id.total_label,R.id.discount_label,R.id.discount_label,R.id.coupon_label,R.id.cost_label}// Keys in childData maps to display.

               

                );

            setListAdapter( expListAdapter );       // setting the adapter in the list.

 

        }catch(Exception e){

            System.out.println("Errrr +++ " + e.getMessage());

        }

    }

   

    /* Creating the Hashmap for the row */

    @SuppressWarnings("unchecked")

    private List createGroupList() {

          ArrayList result = new ArrayList();

          for( int i = 0 ; i < 1 ; ++i ) { // 15 groups........

            HashMap m = new HashMap();

                   map.put( "CustomerInfo","CustomerInfo"); // the key and it's value.

            m.put( "OrderInfo", OrderInfo);

          

            result.add( m);

          }

          return (List)result;

          

    }

          /* each group need each HashMap-Here for each group we have 3 subgroups */

          ArrayList secList = new ArrayList();

          for( int n = 0 ; n < 1 ; n++ ) {

            HashMap child = new HashMap();

            Intent in = getIntent();

            String payment_method = in.getStringExtra(KEY_ARTIST);

            TextView lblPayment = (TextView) findViewById(R.id.payment_label);

         ///  lblPayment.setText(payment_method);

           int payment;

           payment=1;
