CommonDataKinds.Email.ADDRESS给出电话号码？

Question

我想知道为什么在执行此代码时我会收到电话号码而不是电子邮件？有办法解决这个问题吗？

Cursor infoEmail = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
        while (infoEmail.moveToNext()) {
            String email = infoEmail.getString(infoEmail.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS));
            contacts.AddEmail(email);
        }
