问题描述

我需要在用户登录后收集用户名和个人资料图片。我需要在登录过程中执行此操作，我尝试在 onSuccess Methode来自 FacebookCallback< LoginResult> 但是失败了。

I need to collect the user name and the profile picture after the user logged in. I need to do that in the login process, i tried that in the onSuccess Methode from the FacebookCallback<LoginResult> but it failed.

我的代码：

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


        @Override
        public void onSuccess(LoginResult loginResult) {
            final String userId = loginResult.getAccessToken().getUserId();
            final String authToken = loginResult.getAccessToken().getToken();

            // Facebook Name, Profile Picture
            /*GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject object,
                                GraphResponse response) {

                            try {
                                userName = object.getString("name");
                                String url = object.getString("picture");

                                URL facebookProfileURL = new URL(url);
                                Bitmap profPict = BitmapFactory.decodeStream(facebookProfileURL.openConnection().getInputStream());
                                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                                profPict.compress(Bitmap.CompressFormat.JPEG, 100, baos);
                                byte[] b = baos.toByteArray();

                                profilePicAsString = Base64.encodeToString(b, Base64.DEFAULT);

                                facebookAuthObject.setUserId(userId);
                                facebookAuthObject.setAuthToken(authToken);
                                facebookAuthObject.setName(userName);
                                facebookAuthObject.setProfilePictureAsString(profilePicAsString);
                            } catch (JSONException | IOException e) {
                                e.printStackTrace();
                            }
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "name, picture.width(150).height(150)");
            request.setParameters(parameters);
            request.executeAsync();*/


        }

        @Override
        public void onCancel() {
            Log.i(TAG, "User cancel");
        }

        @Override
        public void onError(FacebookException e) {
            Log.e(TAG, e.getLocalizedMessage());
        }
    });

}

我需要像 executeAndWait 但是这是不可能的，因为我在主线程。

I need something like the executeAndWait but this is impossible because I'm on the main thread.

有了这个问题，如果用户离开活动太快我没有什么，因为异步。

With this I have the problem that if the user leave the activity too fast i have nothing, because of the async.

有人有一个想法，我可以阻止ui线程吗？还是其他解决方案收集名称和个人资料图片？

Have anybody an idea how i can block the ui thread? Or other solutions for collecting the name and the profile picture?

提前谢谢
