上面是我的报错日志，我这边遇到这个问题原因也非常简单,意思是说我加载的这个布局的外层没有父布局，通过我检查代码发现我的写法有错误：

 @NonNull
    @Override
    public XiaYiYeHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        xiaYiYeHolder = new XiaYiYeHolder(view);
        return xiaYiYeHolder;
    }


    protected XiaYiYeAdapter(Context context,@LayoutRes int layoutId, List<E> data) {
       view= View.inflate(context,layoutId,null);
        this.layoutId = layoutId;
        this.data = data;
    }

看下更改后的代码：

  @NonNull
    @Override
    public XiaYiYeHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(layoutId, parent, false);
        xiaYiYeHolder = new XiaYiYeHolder(view);
        return xiaYiYeHolder;
    }


    protected XiaYiYeAdapter(@LayoutRes int layoutId, List<E> data) {
        this.layoutId = layoutId;
        this.data = data;
    }

好了完工项目正常跑起来了！！
