如何允许用户在 Android 上使用 Facebook SDK FeedDialogBu​​ilder 更改帖子的目标受众

Question

我正在构建一个 android 应用，并且正在浏览 Facebook SDK 示例，例如 https://developers.facebook.com/docs/reference/dialogs/feed/

我可以使用FeedDialogBuilder 创建要分享的故事，但它只提供Share 和Cancel 选项，并且无法设置受众（特定朋友、列表等）。

这是否可以使用FeedDialogBuilder，还是我需要申请发布权限并建立自己的 Facebook 共享器？

这是我成功登录后使用的代码：

private void publishFeedDialog() {
    Bundle params = new Bundle();
    params.putString("name", "Facebook SDK for Android");
    params.putString("caption", "Build great social apps and get more installs.");
    params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    params.putString("link", "https://developers.facebook.com/android");
    params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
    params.putString("display", "touch");
    WebDialog feedDialog = (
        new WebDialog.FeedDialogBuilder(getActivity(),
            Session.getActiveSession(),
            params))
        .setOnCompleteListener(new OnCompleteListener() {

            public void onComplete(Bundle values,
                FacebookException error) {
                if (error == null) {
                    // When the story is posted, echo the success
                    // and the post Id.
                    final String postId = values.getString("post_id");
                    if (postId != null) {
                        Toast.makeText(getActivity(),
                            "Posted story, id: "+postId,
                            Toast.LENGTH_SHORT).show();
                    } else {
                        // User clicked the Cancel button
                        Toast.makeText(getActivity().getApplicationContext(), 
                            "Publish cancelled", 
                            Toast.LENGTH_SHORT).show();
                    }
                } else if (error instanceof FacebookOperationCanceledException) {
                    // User clicked the "x" button
                    Toast.makeText(getActivity().getApplicationContext(), 
                        "Publish cancelled", 
                        Toast.LENGTH_SHORT).show();
                } else {
                    // Generic, ex: network error
                    Toast.makeText(getActivity().getApplicationContext(), 
                        "Error posting story", 
                        Toast.LENGTH_SHORT).show();
                }
            }

        })
        .build();
    feedDialog.show();
}
