如何使用Facebook SDK Android获取Facebook照片，全名，性别

我正在开发一个Android应用程序，在该应用程序中，任何使用我们的应用程序登录Facebook的Android用户都需要从Facebook中提取其照片，性别和全名。我为此使用Facebook SDK。

借助Facebook SDK，我可以登录Facebook，但不确定如何从Facebook中提取他的照片，性别和全名？

以下是我用来登录Facebook的代码。我遵循了本教程

public class SessionLoginFragment extends Fragment {

    private static final String URL_PREFIX_FRIENDS = "https://graph.facebook.com/me/friends?access_token=";

    private TextView textInstructionsOrLink;
    private Button buttonLoginLogout;
    private Session.StatusCallback statusCallback = new SessionStatusCallback();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment, container, false);

    buttonLoginLogout = (Button) view.findViewById(R.id.buttonLoginLogout);
    textInstructionsOrLink = (TextView) view.findViewById(R.id.instructionsOrLink);

    Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

    Session session = Session.getActiveSession();
    if (session == null) {
        if (savedInstanceState != null) {
        session = Session.restoreSession(getActivity(), null, statusCallback,
            savedInstanceState);
        }
        if (session == null) {
        session = new Session(getActivity());
        }
        Session.setActiveSession(session);
        if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
        session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
        }
    }

    updateView();

    return view;
    }

    @Override
    public void onStart() {
    super.onStart();
    Session.getActiveSession().addCallback(statusCallback);
    }

    @Override
    public void onStop() {
    super.onStop();
    Session.getActiveSession().removeCallback(statusCallback);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    Session session = Session.getActiveSession();
    Session.saveSession(session, outState);
    }

    private void updateView() {
    Session session = Session.getActiveSession();
    if (session.isOpened()) {
        Log.d("Hello", URL_PREFIX_FRIENDS + session.getAccessToken());
        Intent i = new Intent(getActivity(), ThesisProjectAndroid.class);
        startActivity(i);

    } else {
        Log.d("Hello", "Login Failed");
        textInstructionsOrLink.setText(R.string.instructions);
        buttonLoginLogout.setText(R.string.login);
        buttonLoginLogout.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            onClickLogin();
        }
        });
    }
    }

    private void onClickLogin() {
    Session session = Session.getActiveSession();
    if (!session.isOpened() && !session.isClosed()) {
        session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
    } else {
        Session.openActiveSession(getActivity(), this, true, statusCallback);
    }
    }

    private void onClickLogout() {
    Session session = Session.getActiveSession();
    if (!session.isClosed()) {
        session.closeAndClearTokenInformation();
    }
    }

    private class SessionStatusCallback implements Session.StatusCallback {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        updateView();
    }
    }
}

谁能告诉我在上一课中我需要进行哪些更改才能获得我需要的所有三个信息。据我所知，如果我能够获得该人的Facebook唯一ID，我就能获得我猜到的所有信息。有什么想法吗？
