手動展示：
  首先獲取系統訪問者ContnetResolver,
   再通過Uri uri=Uri.parse("content://com.android.contacts/raw_contacts");獲得手機中所有的聯系人Id，以及名字，
   再使用 Uri uriAll=Uri.parse("content://com.android.contacts/raw_contacts/"+id+"/data");根據id查詢該人的電話，
跳轉系統界面，吐司電話號碼：
  Intent intent = new Intent(Intent.ACTION_PICK,                        ContactsContract.Contacts.CONTENT_URI);                MainActivity.this.startActivityForResult(intent, 1);
 跳轉到系統的聯系人選擇界面，只能單選；
   通過回調方法傳回來的值，判斷有無選中；
   有選中獲得號碼，吐司； 
   無則無操作；
