調用ListView對象的setOnItemClickListener()方法，設置條目的點擊事件，參數：OnItemClickListener對象

使用匿名內部類實現，重寫onClick()方法，傳遞進來的參數：ListView，當前View，position,id

根據索引位置把當前這條電話號碼傳回去

調用List對象的get()方法，得到Map，調用get(key)方法，得到這條電話

調用setResult()方法，返回去數據，參數：響應碼，Intent對象

獲取Intent對象，new出來

調用Intent對象的putExtra(key,val)，把電話放進去

調用finish()方法關閉當前頁面

開啟這個的activity使用的是startActivityForResult()

重寫onActivityResult()方法，傳遞進來Intent對象

判斷Intent對象是否為null
