【Android异常】The specified child already has a parent. You must call removeView() on the child's paren

出现这种错误，使用过程是Fragment和RadioButton使用的时候，加载了这段代码

 @Override
    public View createView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view=inflater.inflate(R.layout.index_fragment_layout,container);
        return view;
    }

应该改为

 @Override
    public View createView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view=inflater.inflate(R.layout.index_fragment_layout,container,false);
        return view;
    }

加载View的参数应该加上false，原因暂时还不明白，应该是attach  parentView，需要看下源码
