当我回应时，我得到

如果对我的应用程序有任何疑问，请告诉我。

将
onClickListener
的部分更改为我的代码：

btnLoginFb.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {

    @Override
    public void onSuccess(LoginResult loginResult) {

        System.out.println("onSuccess");
        progressDialog = new ProgressDialog(LoginActivity.this);
        progressDialog.setMessage("Procesando datos...");
        progressDialog.show();
        String accessToken = loginResult.getAccessToken().getToken();
        Log.i("accessToken", accessToken);

        GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {

            @Override
            public void onCompleted(JSONObject object, GraphResponse response) {
                Log.i("LoginActivity", response.toString());

希望，它也会对你有帮助：）

试试这个它对我有用希望它对你也有用

在主活动或使用FaceBookSignIn方法的活动中调用此函数
