当我在BaseExpandableListAdapter中时，如何附加我的YouTubePlayerSupportFragment？

Question

我之前在片段中所做的是：

YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();

youTubePlayerFragment.initialize(/* .. */);
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.fl_youtube, youTubePlayerFragment).commit();

这很好用。但是现在我有一个BaseExpandableListAdapter来设置getChildView中展开的内容。没有getChildFragmentManager。我现在该怎么办？

public View getChildView(int groupPosition, 
                         int childPosition, 
                         boolean isLastChild, 
                         View convertView, 
                         ViewGroup parent) {
   // How do I add attach the YouTubeFragment?
}
