//Let's create an item with R.layout.expanding_layout
item = mExpandingList.createNewItem(R.layout.expanding_layout);
item.createSubItems(arrsubItem.size());
//item.createSubItems(getTodaySummaryDetailResult.getMTodaySummaryDetail().getLstSubitem().size());
for (int ijk = 0; ijk < item.getSubItemsCount(); ijk++) {

                View view = item.getSubItemView(ijk);


                TextView subtitle1= (TextView) view.findViewById(R.id.sub_title);
                TextView txt_gwt = (TextView)view.findViewById(R.id.txt_gwt);
                TextView subAmount123 = (TextView)view.findViewById(R.id.sub_amount);
                subtitle1.setText(arrsubItem.get(ijk).getSubTitle());
                double d1 = Double.parseDouble(arrsubItem.get(ijk).getSubAmount()+"");
                NumberFormat formatter = new DecimalFormat("###.#####");
