Android Fragment 回调不到onActivityR

第一种解决办法：不要用getActivity().startActivity()去跳转
第二种解决办法：

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        adapter.getItem(0).onActivityResult(requestCode, resultCode, data);
    }
