Here I am accessing name and phone number from mobile and uploading to server. I am not facing any problem in this. I have made some modifications to access email also. But I am not able to fetch the email. In place of email it is displaying phone number. I have used System.out.print to check the details. Here is my code.

DisplayContact

        }

        @Override
        public void onCheckedChanged(CompoundButton buttonView,
                                     boolean isChecked) {

            mCheckStates.put((Integer) buttonView.getTag(), isChecked);
        }
    }

}

我想我似乎在这部分中缺少了一些东西.

I think I am missing something in this part it seems.

phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");

推荐答案

尝试一下:-

private String retriveContactEmail(Uri uriContact) {
    String useremail = null;
    // getting contacts ID
    Cursor cursorID = getActivity().getContentResolver().query(uriContact, new String[]{ContactsContract.Contacts._ID}, null, null, null);

    if (cursorID.moveToFirst()) {
        contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
    }

    cursorID.close();
    // get email and type
    Cursor emailCur = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{contactID}, null);
    while (emailCur.moveToNext()) {
        // This would allow you get several email addresses
        // if the email addresses were stored in an array
        String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
        String emailType = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
        useremail = email;
    }
    emailCur.close();

    return useremail;
}
