public void getProfileInformation_fb() {
        mAsyncRunner.request("me", new RequestListener() {
            @Override
            public void onComplete(String response, Object state) {

                String json = response;
                try {
                    JSONObject profile = new JSONObject(json);
                    // getting name of the user

                    final String name = profile.getString("name");
                    // getting email of the user
                    final String email = profile.getString("email");

                    final String id = profile.getString("id");


                    Log.i("ID , Name", ""+id+ ""+name);

                    Log.i("Email", ""+email);

此代码 ID 对我有用。

  LoginManager.getInstance().registerCallback(callbackManager,
                new FacebookCallback<LoginResult>() {
                    @Override
                    public void onSuccess(LoginResult loginResult) {
                        // App code
                        accessToken = loginResult.getAccessToken();


                        GraphRequest request = GraphRequest.newMeRequest(
                                accessToken,
                                new GraphRequest.GraphJSONObjectCallback() {
                                    @Override
                                    public void onCompleted(
                                            JSONObject object,
                                            GraphResponse response) {
                                        // Application code

                                        try {

 String name = object.getString("name");
                    String birthday = object.getString("birthday");
                    String gender = object.getString("gender");
                    String email = object.getString("email");
                    String picture = object.getString("picture");






                                        } catch (Exception e) {
                                            e.printStackTrace();
                                        }










                                    }
                                });
                        Bundle parameters = new Bundle();
                        parameters.putString("fields", "id,name,link,birthday,first_name,gender,last_name,location,email,picture.type(large)");
                        request.setParameters(parameters);
                        request.executeAsync();







                    }

                    @Override
                    public void onCancel() {
                        // App code
                        Log.e("fb", "cancel ");
                        LoginManager.getInstance().logOut();
                    }

                    @Override
                    public void onError(FacebookException exception) {
                        // App code
                        Log.e("fb", "error " + exception);
                        LoginManager.getInstance().logOut();
                    }
                });
