In order to get the list view child

 lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        View c = lv.getChildAt(position);
        // c is your list view child which is clicked
        final TextView tv = (TextView) c.findViewById(R.id.qty1);
        // tv is your textview of whom vwlue you have to change.
        //changes the value of textview here and den notify data set changed and refresh the list.         
       }
     });
