 關鍵程式碼給下拉選單選中事件監聽繫結Id ：

[html] view plaincopy
  1. int pos = firsthand_dlbh_pinner.getSelectedItemPosition();  
  2. firsthand_pdbh_adapter = new ArrayAdapter<String>(context,  
  3.         android.R.layout.simple_spinner_item, queu_info[pos]);  
  4. firsthand_pdbh_spinner.setAdapter(firsthand_pdbh_adapter);
