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;
}
