With the help of Facebook SDK, I am able to login into Facebook but I am not sure how to extract his photo,gender and full name from the facebook?

下面是我用来登录Facebook的代码。我遵循了这个教程

Below is the code I am using to login into Facebook. I followed this tutorial

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();
    }
    }
}

有谁能告诉我哪里需要在上述类中进行更改以获取我需要的所有三个信息。据我所知，如果我能够获得Facebook的独特ID，我可以得到我所有的信息。任何想法？

Can anyone tell me where I need to make changes in the above class to get all the three information I needed. As far as I know If I am able to get facebook unique id for that person, I can get all the information I guess. Any thoughts?

推荐答案

在您的 StatusCallback 函数中，您可以获得细节来自 GraphUser 对象

In your StatusCallback function, you can get the details from the GraphUser object

private class SessionStatusCallback implements Session.StatusCallback {
    private String fbAccessToken;

    @Override
    public void call(Session session, SessionState state, Exception exception) {
        updateView();
        if (session.isOpened()) {
            fbAccessToken = session.getAccessToken();
            // make request to get facebook user info
            Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
                @Override
                public void onCompleted(GraphUser user, Response response) {
                    Log.i("fb", "fb user: "+ user.toString());

                    String fbId = user.getId();
                    String fbAccessToken = fbAccessToken;
                    String fbName = user.getName();
                    String gender = user.asMap().get("gender").toString();
                    String email = user.asMap().get("email").toString();

                    Log.i("fb", userProfile.getEmail());
                }
            });
        }
    }
}
