我在这里从移动设备访问姓名和电话号码并上传到服务器。我没有遇到任何问题。我也对访问电子邮件进行了一些修改。但我无法取电子邮件。它代替电子邮件显示电话号码。我使用System.out.print来查看详细信息。这是我的代码。

我认为我似乎错过了这部分内容。
phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");
答案 0 :(得分：0)
试试这个： -
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;
}
