Android，無法訪問聯繫人電話號碼

Question

我無法訪問我的聯繫人的電話號碼，無法弄清楚原因。

private void getContacts(){ 
     Cursor people = mCon.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
     if (people.moveToFirst()) { 
      do { 
       int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME); 
       String contact = people.getString(nameFieldColumnIndex).toLowerCase(); 
       int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER); 
       String number = people.getString(numberFieldColumnIndex); 
       hm.put(contact, number); 
      }while(people.moveToNext()); 
     } 
     people.close(); 
    } 

名稱正在進入HashMap的罰款，但numberFieldColumnIndex不斷出來爲-1

我輸出的人列標題，並沒有一個號碼是多少？我如何檢索它們？人們

列表的列標題下面的代碼顯示了一個簡單的方法來讀取所有的電話號碼和姓名：

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); 
while (phones.moveToNext()) 
{ 
    String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
    String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 

} 
phones.close();
