我如何从最新的Facebook sdk-4.0.1获取用户信息

Question

How can i get user information from Latest Facebook sdk-4.0.1 ,, like :

email - user_birthday - user_friends

Notice : I use LoginButton

    final LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
    loginButton.setReadPermissions("user_friends");
    loginButton.setReadPermissions("public_profile");
    loginButton.setReadPermissions("email");
    loginButton.setReadPermissions("user_birthday");

Answer 1

First, the permissions can be setup in one line:

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

Now, considering you registered a callback in this way:

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) { }

        @Override
        public void onCancel() { }

        @Override
        public void onError(FacebookException exception) { }
    });

Place this code in the onSuccess() method:

        GraphRequest request = GraphRequest.newMeRequest( loginResult.getAccessToken(),
                new GraphRequest.GraphJSONObjectCallback() {
                    @Override
                    public void onCompleted( JSONObject object,  GraphResponse response) {
                        Log.d("onCompleted",object.toString());
                    }
                });
        Bundle parameters = new Bundle();
        parameters.putString("fields", "id,name,link, email");
        request.setParameters(parameters);
        request.executeAsync();

Pay attention in this line:

parameters.putString("fields", "id,name,link, email");

...these will be the fields returned in the JSONObject in the onCompleted() method.
