Banner放在MotionLayout中做动画，MotionLayout对应的layoutDescription：motion scene文件操作包裹Banner的Constraint开始结束设置关键属性visibility，最容易复现，基本是百分之百复现
复现之后，滑动一下Banner（也就是滑动一下RecyclerView）之后，onBindViewHolder方法才会被调用
如果Banner用RecyclerView代替，操作后再调用notifyItemChanged其onBindViewHolder可以被正常调用
[为此我做了一个demo来对比两者的不同表现（其中的item操作事件放在了onBindViewHolder方法中，是因为在onCreateViewHolder中获取postion也有问题，有时候会返回-1，而且正常情况也会返回错误，比如holder.getBindingAdapterPosition()，故放在onBindViewHolder）
