Question

我查看了facebook developers上的教程，它与我在互联网上找到的内容有所不同。哪一个是实现Facebook登录的最佳方式？另外，在哪里学习facebook sdk for android的最好的地方，似乎官方的还不完整？

Facebook.developer使用loginButton.setRegisterCallback（）;

@Override
public View onCreateView(
        LayoutInflater inflater,
        ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.splash, container, false);

    loginButton = (LoginButton) view.findViewById(R.id.login_button);
    loginButton.setReadPermissions("user_friends");
    // If using in a fragment
    loginButton.setFragment(this);    
    // Other app specific specialization

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
        }

        @Override
        public void onCancel() {
            // App code
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
        }
    });    
}

programmerguru.com使用我在官方网站上找不到的UiLifecycleHelper

public class MainActivity extends ActionBarActivity {
    // Create, automatically open (if applicable), save, and restore the 
    // Active Session in a way that is similar to Android UI lifecycles. 
    private UiLifecycleHelper uiHelper;
    private View otherView;
    private static final String TAG = "MainActivity";
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // Set View that should be visible after log-in invisible initially
        otherView = (View) findViewById(R.id.other_views);
        otherView.setVisibility(View.GONE);
        // To maintain FB Login session
        uiHelper = new UiLifecycleHelper(this, callback);
        uiHelper.onCreate(savedInstanceState);
    }
     
    // Called when session changes
    private Session.StatusCallback callback = new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            onSessionStateChange(session, state, exception);
        }
    };
     
    // When session is changed, this method is called from callback method
    private void onSessionStateChange(Session session, SessionState state,
            Exception exception) {
        final TextView name = (TextView) findViewById(R.id.name);
        final TextView gender = (TextView) findViewById(R.id.gender);
        final TextView location = (TextView) findViewById(R.id.location);
        // When Session is successfully opened (User logged-in)
        if (state.isOpened()) {
            Log.i(TAG, "Logged in...");
            // make request to the /me API to get Graph user
            Request.newMeRequest(session, new Request.GraphUserCallback() {
 
                // callback after Graph API response with user
                // object
                @Override
                public void onCompleted(GraphUser user, Response response) {
                    if (user != null) {
                        // Set view visibility to true
                        otherView.setVisibility(View.VISIBLE);
                        // Set User name 
                        name.setText("Hello " + user.getName());
                        // Set Gender
                        gender.setText("Your Gender: "
                                + user.getProperty("gender").toString());
                        location.setText("Your Current Location: "
                                + user.getLocation().getProperty("name")
                                        .toString());
                    }
                }
            }).executeAsync();
        } else if (state.isClosed()) {
            Log.i(TAG, "Logged out...");
            otherView.setVisibility(View.GONE);
        }
    }
     
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
 
        uiHelper.onActivityResult(requestCode, resultCode, data);
        Log.i(TAG, "OnActivityResult...");
    }
     
    @Override
    public void onResume() {
        super.onResume();
        uiHelper.onResume();
    }
 
    @Override
    public void onPause() {
        super.onPause();
        uiHelper.onPause();
    }
 
    @Override
    public void onDestroy() {
        super.onDestroy();
        uiHelper.onDestroy();
    }
 
    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        uiHelper.onSaveInstanceState(outState);
    }
}

Answer 1

正如@Ming Li所说，坚持the official tutorials。之所以有许多不同的教程，是因为Facebook SDK有许多不同的版本，每个版本可能会有不同的方式与Facebook做事。如果他们想出更好的想法来与Facebook做事，他们就会改变它。

在Android上实施Facebook登录的最佳方式是什么？
