java - 无法将我的 android 应用程序中的 facebook 发布到给定的 postId

Question

我正在尝试从我的 Android 应用程序向给定的 postId = 10154194181895153 发布一个 facebook。

我已经阅读了很多这样做的方法。

但是他们每个人都返回了一个fb响应错误。

你能解释一下A和B的区别吗？

我曾尝试将 A 移动到 asyncTask (C)，但如您所见，它没有帮助。

fbLikeBtn.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        // fbLike_optionA();
                        // fbLike_optionB();
                        fbLike_optionC();

                    }

选项A

{Response:  responseCode: 200, graphObject: null, error: {HttpStatus: -1, errorCode: -1, errorType: null, errorMessage: android.os.NetworkOnMainThreadException}, isFromCache:false}

.

private void fbLike_optionA() {

    SharedPreferences prefs = mOffersListActivity.getSharedPreferences(
            PublicMacros.SP_NAME, Context.MODE_PRIVATE);

    String fbAccessToken = prefs
            .getString(PublicMacros.FB_ACCESS_TOKEN, "");

    Bundle params = new Bundle();
    params.putString("object", "http://samples.ogp.me/10154194181895153");
    params.putString("access_token", fbAccessToken);

    Request request = new Request(Session.getActiveSession(),
            "me/og.likes", params, HttpMethod.POST);
    Response response = request.executeAndWait();
    // handle the response
}

选项 B

{Response:  responseCode: 400, graphObject: null, error: {HttpStatus: 400, errorCode: 104, errorType: OAuthException, errorMessage: An access token is required to request this resource.}, isFromCache:false}

.

private void fbLike_optionB() {
                    Request.Callback callback = new Request.Callback() {
                        public void onCompleted(Response response) {

                            if (response != null) {
                                FacebookRequestError error = response
                                        .getError();

                                if (error != null) {
                                    // error
                                } else {
                                    // success
                                }
                            }
                        }
                    };

                    Request request = new Request(Session
                            .getActiveSession(), "10154194181895153/likes",
                            null, HttpMethod.POST, callback);

                    RequestAsyncTask task = new RequestAsyncTask(request);
                    task.execute();

                }

选项 C

{Response:  responseCode: 400, graphObject: null, error: {HttpStatus: 400, errorCode: 2500, errorType: OAuthException, errorMessage: An active access token must be used to query information about the current user.}, isFromCache:false}

.

private void fbLike_optionC() {
                    new LikeFbPostAsyncTask(mCurrentlockImage)
                            .execute("10154194181895153");
                }



public class LikeFbPostAsyncTask extends AsyncTask<String, Void, Void> {
        ImageButton mLockImage;
        Response fbServerResponse;

        public LikeFbPostAsyncTask(ImageButton lockImage) {
            mLockImage = lockImage;
        }

        @Override
        protected void onPreExecute() {
            Log.i("LikeFbPostAsyncTask", "Starting web task...");
        }

        @Override
        protected Void doInBackground(String... fbPostId) {
            fbLike_optionA();
            return null;
        }

        @Override
        protected void onPostExecute(Void res) {
        }
    }

选项 D

     Request likeRequest = new Request(Session.getActiveSession(),
     fbPostId[0] + "/likes", null, HttpMethod.POST,
     new Request.Callback() {

     // here is non-ui thread
     @Override
     public void onCompleted(final Response response) {
     Log.i(TAG, response.toString());
     fbServerResponse = response;

     }
     });
     Request.executeBatchAndWait(likeRequest);

尝试使用这个库:

dependencies {
    compile 'com.shamanland:facebook-like-button:0.1.8'
}

最简单的添加点赞按钮的方法:

<com.shamanland.facebook.likebutton.FacebookLikeButton
    style="@style/Widget.FacebookLikeButton"
    app:pageUrl="http://url.to.like/page.html"
    app:pageTitle="Title of page"
    app:pageText="Short description of page"
    app:pagePictureUrl="http://url.to.like/picture.jpg"
    />

此 View 将绘制在您的布局中:

点击它后，您将看到带有官方 Facebook“赞”插件的对话框。
