第一個RecyclerView的Adapter

@Override
    public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.shop_item,null); 解決條目顯示不全
        MyHolder holder = new MyHolder(view);
        return holder;
    }

 @Override
    public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.check_item, parent,false);//解決寬度不能鋪滿
        MyHolder holder = new MyHolder(view);
        return holder;
    }
