我无法在用户的墙上设置一个简单的 facebook 墙贴。我希望在单击带有缩略图、描述和标题的按钮时弹出一个 facebook 对话框。我尝试了以下代码，但没有弹出对话框：

shareOnFacebookBtn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {

                /*
                 * Get existing access_token if any
                 */
                mPrefs ShopDetailActivity.this.getActivity().getPreferences(Context.MODE_PRIVATE);
                String access_token = mPrefs.getString("access_token", null);
                long expires = mPrefs.getLong("access_expires", 0);
                if(access_token != null) {
                    facebook.setAccessToken(access_token);
                }
                if(expires != 0) {
                    facebook.setAccessExpires(expires);
                }

                /*
                 * Only call authorize if the access_token has expired.
                 */
                if(!facebook.isSessionValid()) {    

                facebook.authorize(ShopDetailActivity.this.getActivity(),new String[] { "publish_stream" }, new DialogListener() {
                    @Override
                    public void onComplete(Bundle values) {

                        SharedPreferences.Editor editor = mPrefs.edit();
                        editor.putString("access_token", facebook.getAccessToken());
                        editor.putLong("access_expires", facebook.getAccessExpires());
                        editor.commit();
                        //facebook.dialog(ShopDetailActivity.this.getActivity(), "feed", new SampleDialogListener());
                        Bundle parameters = new Bundle();
                        parameters.putString("message", "message");// the message to post to the wall
                        facebook.dialog(context, "feed", parameters, this);

                    }

                    @Override
                    public void onFacebookError(FacebookError error) {}

                    @Override
                    public void onError(DialogError e) {}

                    @Override
                    public void onCancel() {}
                });


              } 
            }

        });

授权窗口打开，单击允许后，我希望对话框弹出，但它只是返回到应用程序。我究竟做错了什么？
