我在使用中提取一些人的电话号码在我的联系人列表中的问题。

I'm having a problem with extracting phone numbers of some people in my contact list.

首先，我显示一个列表视图中的所有联系人：

First I show all the contacts in a listview:

String[] projection = new String[] {
            ContactsContract.Contacts._ID,
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER
    };

mCursor = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            projection, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[] {mContactId}, null);

当一个项目点击，这是我取CONTACT_ID：

When clicking on an item, this is how I fetch the contact_id:

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
        Cursor currentCursor = mContactsAdapter.getCursor();

    if (currentCursor != null) {
        notifyOnContactSelectedListeners(String.valueOf(id));
    }
}

然后，我创建一个新的片段，并在加载它，我查询了联系人的电话和放大器;显示名称：

Then I create a new fragment, and while loading it I query for the contact's phone & display name:

if (cursor != null && cursor.getCount() > 0) {

        cursor.moveToFirst();

        String firstName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    }

所以，对某些人来说，有一个电话，我得到的电话号码，这样一来，不过没关系。 但对某些人，我不能得到的电话号码这样 - 但他们确实有默认的手机电话本的电话号码

So for some people that has a phone, I get the phone number this way and that's ok. But for some people I can't get the phone number this way - but they do have phone number in the default's phone contacts book.

出了什么问题？
