Android 联系人选择器获取姓名 + 号码 + 电子邮件

Question

我在使用联系人选择器时遇到问题，它适用于 Phone.DISPLAY_NAME 和 Phone.NUMBER 但不适用于 Email.ADDRESS

public class CustomerForm extends Activity {
private final static int CONTACT_PICKER = 1;
private EditText txtMailContacto;
private EditText txtNombreContacto;
private EditText txtTelefono;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_customer_form);
    txtMailContacto = (EditText) findViewById(R.id.txtMailContacto);
    txtTelefono = (EditText) findViewById(R.id.txtTelefono);
    txtNombreContacto = (EditText) findViewById(R.id.txtNombreContacto);
}
public void pickContact(View v)
{
    Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
            ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
    startActivityForResult(contactPickerIntent, CONTACT_PICKER);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // check whether the result is ok
    if (resultCode == RESULT_OK) {
        // Check for the request code, we might be usign multiple startActivityForReslut
        switch (requestCode) {
        case CONTACT_PICKER:
            contactPicked(data);
            break;
        }
    } else {
        Log.e("MainActivity", "Failed to pick contact");
    }
}
private void contactPicked(Intent data) {
    Cursor cursor = null;
    try {
        String mail = null ;
        String phoneNo = null ;
        String name = null;
        // getData() method will have the Content Uri of the selected contact
        Uri uri = data.getData();
        //Query the content uri
        cursor = getContentResolver().query(uri, null, null, null, null);
        cursor.moveToFirst();
        // column index of the phone number
        int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
        // column index of the email
        int  mailIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS);
        // column index of the contact name
        int  nameIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
        mail = cursor.getString(mailIndex);
        phoneNo = cursor.getString(phoneIndex);
        name = cursor.getString(nameIndex);
        // Set the value to the textviews
        txtMailContacto.setText(mail);
        txtTelefono.setText(phoneNo);
        txtNombreContacto.setText(name);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
}

所以，我正在尝试获取这些字段，但我无法弄清楚问题出在哪里。 感谢您的帮助...
