Answer 1

在該方法onItemClick()獲取對應於位置（位置參數）的行點擊，更新該值，然後通知該數據已與呼叫改變到方法notifyDataSetChanged()適配器中PhoneBook元件：

list.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View view, int position, long index) { 
       // make the adapter a field in your class (or final) 
       PhoneBook element = (PhoneBook) adapter.getItem(position); 
       //modify the PhoneBook element 
       element.setPhone("555-555-555"); 
       // notify the adapter that something has changed 
       adapter.notifyDataSetChanged(); 
       showToast(listOfPhonebook.get(position).getName()); 
      } 
     });
