java - 連絡先リスト Android からユーザー情報を取得する

Question

連絡先リストの各連絡先から名前、電子メール、電話番号を取得する必要があります。

問題は、名前と電話番号を取得できますが、電子メールを取得できないことです。メールの代わりに電話番号を取得しています。

これが私のコードです：

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));
            String email = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS));

            ContactItem objContact = new ContactItem();
            objContact.setName(name);
            objContact.setPhoneNo(phoneNumber);
            objContact.setEmail(email);
            list.add(objContact);

        }
        phones.close();

public void onActivityResult(int reqCode, int resultCode, Intent data) { super.onActivityResult(reqCode, resultCode, data);

    switch (reqCode) {
    case (PICK_CONTACT):
        if (resultCode == Activity.RESULT_OK) {
            String phoneNumber = null;
            String name = null;
            String emailAddress = null;

            Uri contactData = data.getData();
            Cursor c = managedQuery(contactData, null, null, null, null);

            if (c.moveToFirst()) {
                Cursor cursor = null;

                cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
                while (cursor.moveToNext()) {
                    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                    name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
                    // May want to get basic info here like name, phone
                    // Example:
                    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId,
                            null, null);
                    while (phones.moveToNext()) {
                        phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        Log.i("phone", phoneNumber);
                    }
                    phones.close();

                    Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,
                            null, null);
                    while (emails.moveToNext()) {
                        emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                        Log.i("emails", emailAddress);
                    }
                    emails.close();
                }
                cursor.close();

                Log.i(DEBUG_TAG, "Got a contact result: " + name + emailAddress + "Phone Number is :- " + phoneNumber);
                Toast.makeText(getApplicationContext(), name, Toast.LENGTH_SHORT).show();

            }
        }
    }
}
