Android，無法訪問聯系人電話號碼

Question

我無法訪問聯系人的電話號碼，也無法找出原因。

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();
    }

名稱進入hashmap很好，但numberFieldColumnIndex始終顯示為-1

我輸出的人的列標題是不是沒有一個數字？ 我該如何找回它們？

以下代碼顯示了一種讀取所有電話號碼和姓名的簡便方法：

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();
