Android Facebook 4.0 SDK如何获取电子邮件,出生日期和用户性别

Sri*_*tha 140 android facebook-android-sdk facebook-sdk-4.0

我使用以下代码.我想要用户的出生日期,电子邮件和性别.请帮忙.如何检索这些数据？

这是我onViewCreated()在片段中的内容.

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {

    // Setup TextView.
    mTextDetails = (TextView) view.findViewById(R.id.text_details);

    // Set up Login Button.
    LoginButton mButtonLogin = (LoginButton) view.findViewById(R.id.login_button);
    // setFragment only if you are using it inside a Fragment.
    mButtonLogin.setFragment(this);
    mButtonLogin.setReadPermissions("user_friends");
    mButtonLogin.setReadPermissions("public_profile");
    mButtonLogin.setReadPermissions("email");
    mButtonLogin.setReadPermissions("user_birthday");

    // Register a callback method when Login Button is Clicked.
    mButtonLogin.registerCallback(mCallbackManager, mFacebookCallback);

}

这是我的回调方法.

private FacebookCallback<LoginResult> mFacebookCallback = new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {
        Log.d("Shreks Fragment", "onSuccess");


        Profile profile = Profile.getCurrentProfile();
        Log.d("Shreks Fragment onSuccess", "" +profile);

        // Get User Name
        mTextDetails.setText(profile.getName() + "");

    }


    @Override
    public void onCancel() {
        Log.d("Shreks Fragmnt", "onCancel");
    }

    @Override
    public void onError(FacebookException e) {
        Log.d("Shreks Fragment", "onError " + e);
    }
};

这不是设置权限的正确方法,因为每次方法调用都会覆盖它们.

替换这个:

mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");

使用以下方法,因为该方法setReadPermissions()接受ArrayList:

loginButton.setReadPermissions(Arrays.asList(
        "public_profile", "email", "user_birthday", "user_friends"));

这里还有如何查询额外的数据GraphRequest:

private LoginButton loginButton;
private CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    loginButton = (LoginButton) findViewById(R.id.login_button);

    loginButton.setReadPermissions(Arrays.asList(
            "public_profile", "email", "user_birthday", "user_friends"));

    callbackManager = CallbackManager.Factory.create();

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {

                            // Application code
                            String email = object.getString("email");
                            String birthday = object.getString("birthday"); // 01/31/1980 format
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday");
            request.setParameters(parameters);
            request.executeAsync();


        }

编辑:

一个可能的问题是Facebook假定您的电子邮件无效.要测试它,请使用Graph API Explorer并尝试获取它.即使在那里,您也无法收到电子邮件,请在个人资料设置中进行更改,然后重试.这种方法解决了这个问题,一些开发人员评论我的答案.

  • 我只想说Facebook Docs太差了!我们需要找到如何在这里做到这一点,这是一种耻辱. (80认同)
  • 除了电子邮件,如何获得电子邮件,它工作正常？ (3认同)
  • 尽管我已经设置了`loginButton.setReadPermissions(Arrays.asList("public_profile","email")),为什么我会收到"没有电子邮件的价值"错误;`？ (3认同)
  • 嘿@Schwertfisch你能展示如何使用object.getString("email"); ,这对我很有帮助:) (2认同)
  • 没有为我工作,我没有收到电子邮件 (2认同)

你不会得到onSuccess()你需要实现的配置文件ProfileTracker以及注册回调

mProfileTracker = new ProfileTracker() {
    @Override
    protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
        // Fetch user details from New Profile
    }
};

另外,不要忘记处理配置文件跟踪器的启动和停止

现在,您将拥有一个从中获取AccessToken的配置文件(解决了null配置文件的问题).您只需使用" https://developers.facebook.com/docs/android/graph#userdata "获取任何数据.

  • 我将其作为Access令牌:{AccessToken令牌:ACCESS_TOKEN_REMOVED权限:[user_friends,email,user_birthday,basic_info]}我在FacebookCallBack下使用此代码---- AccessToken mAccessToken = loginResult.getAccessToken(); 你能告诉我这是什么意思吗？以及如何解决此错误并获取Access令牌？ (2认同)
