3             public void onItemSelected(AdapterView<?> parent, View view,
4                     int position, long id) {
5                 // TODO Auto-generated method stub
6                 // 将选择的数据转换成String类型
7                 String itemname = parent.getItemAtPosition(position).toString();
8                 selectitem = itemname;
