java - Android facebook sdk 使用graph api

Question

我在网上阅读了很多指南，但我还不明白如何在我的 android 应用程序中使用 Graph API。

我有这个 fragment ，其中我有一个 Facebook 登录。登录有效，但我不知道如何获取 Facebook 用户和 ID

这是我的整个 fragment :

public class SampleFragment extends Fragment {

    private static final String ARG_POSITION = "position";
    private WebView myWebView;
    private String LOG_TAG = "AndroidWebViewActivity";

    private int position;


    public static SampleFragment newInstance(int position) {
        SampleFragment f = new SampleFragment();
        Bundle b = new Bundle();
        b.putInt(ARG_POSITION, position);
        f.setArguments(b);
        return f;
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(
                    JSONObject object,
                    GraphResponse response) {
                Log.i("**********", String.valueOf(object));
            }
        };

        position = getArguments().getInt(ARG_POSITION);
        View rootView = inflater.inflate(page, container, false);
        FloatingActionButton fab = (FloatingActionButton) rootView.findViewById(R.id.fabButton);
        final ProgressBarCircular progressBarCircular = (ProgressBarCircular) rootView.findViewById(R.id.progress);



        final WebView webView = (WebView) rootView.findViewById(R.id.webView);



        webView.getSettings().setBuiltInZoomControls(false);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setAllowContentAccess(true);

        webView.getSettings().setAllowUniversalAccessFromFileURLs(true);
        webView.getSettings().setAllowFileAccessFromFileURLs(true);
        webView.getSettings().setAllowContentAccess(true);
        webView.getSettings().setAppCacheEnabled(true);


        webView.getSettings().setSupportZoom(false);
        webView.setInitialScale(0);

        LoginButton loginButton = (LoginButton) rootView.findViewById(R.id.login_button);
        loginButton.setReadPermissions("user_friends");
        // If using in a fragment
        loginButton.setFragment(this);
        // Other app specific specialization

        CallbackManager callbackManager = CallbackManager.Factory.create();


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



                            }
                        });

                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,name,link");
                request.setParameters(parameters);
                request.executeAsync();

                Log.i("LOGIN", "***************************");
                Log.i("LOGIN", String.valueOf(loginResult));





            }

            @Override
            public void onCancel() {

            }

            @Override
            public void onError(FacebookException exception) {

            }

        });





        switch (position) {
            case 0:
