android之针对fragment多次调用onCreateView的问题

private View rootView;
@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        if (null != rootView) {
            ViewGroup parent = (ViewGroup) rootView.getParent();
            if (null != parent) {
                parent.removeView(rootView);
            }
        } else {
            rootView = inflater.inflate(layoutId, null);
            initView(rootView);// 控件初始化
        }
        return rootView;
    }
