共享对话框中未显示我的自定义打开图形对象的自定义属性

Question

我无法获取我的Android应用程序的"共享"对话框中显示的自定义Open Graph对象的自定义属性.我在命名空间myradio_android中创建了一个自定义对象通道,并在通道中定义了一个自定义属性current_song_title.我还创建了一个自定义操作享受,但我无法在共享对话框中显示我的自定义属性current_song_title.我得到的可以看到下面粘贴的图像.

这是我用来创建"共享"对话框的代码:

    // Facebook
    mImageButtonShareOnFacebook = (ImageButton)view.findViewById(R.id.shareOnFacebook);
    mImageButtonShareOnFacebook.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            FacebookSdk.sdkInitialize(getActivity().getApplicationContext());

            SharePhoto photo = new SharePhoto.Builder()
                    .setBitmap(_albumCover)
                    .setUserGenerated(true)
                    .build();

            // Create an object
            ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
                    .putString("og:type", "myradio_android:channel")
                    .putString("og:title", channel.getName())
                    .putString("og:description", "My description")
                    .putString("myradio_android:channel:current_song_title", _title)
                    .putPhoto("og:image", photo)
                    .build();


            // Create an action
            ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
                    .setActionType("myradio_android:enjoy")
                    .putObject("channel", object)

                    .build();

            // Create the content
            ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
                    .setPreviewPropertyName("channel")
                    .setAction(action)
                    .build();

            ShareDialog.show(NowPlayingFragment.this, content);

        }
    });

而不是myradio_android:channel:current_song_title尝试myradio_android:current_song_title
