我想动态地将youtube片段添加到我已经存在的片段中.我使用的代码如下：

        // setting the Youtube Player Dynamically
private int setYoutubePlayer(String desc,View view,int prevID,Bundle input) {

    if (desc.indexOf("=") != -1) {
        desc = desc.substring(desc.indexOf("=") + "=".length());
    } else {
        return prevID;
    }

    final String url = desc;

    LinearLayout videoLayout = new LinearLayout(view.getContext());
    videoLayout.setOrientation(LinearLayout.VERTICAL);
    prevID++;
    videoLayout.setId(prevID);

    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager
            .beginTransaction();

    fragment.setVideoId(url);
    LinearLayout itemLayout = (LinearLayout) view.findViewById(R.id.items);
    itemLayout.addView(videoLayout);

    fragmentTransaction.add(itemLayout.getId(),fragment,"youtube fargment " + prevID);

    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();

    return prevID;
}

我需要在适当的片段中获取youtube片段.当我检查总是加载一个新片段时(当在片段之间滑动时),新的内部片段需要是第一个加载的片段.

任何帮助都会很乐意接受.

解决：谢谢你Koby你是对的.我不得不替换“getActivity().getSupportFragmentManager();”使用“getChildFragmentManager()”.问题显然是Sherlock库附带了一个旧的android v4支持库.我不得不更新Sherlock中的支持库.它对我有用…..
