Description
目前源码中BaseQuickAdapter中实现：
abstract class BaseQuickAdapter<T : Any, VH : RecyclerView.ViewHolder>(
open var items: List = emptyList()
) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {
}
adapter重载onViewRecycled方法时：
override fun onViewRecycled(holder: RecyclerView.ViewHolder) {
super.onViewRecycled()
}
这样需要对holder进行转换才能得到对应的ViewBinding,建议继承RecyclerView.Adapter和之前版本实现一样传入泛型VH，改成：
abstract class BaseQuickAdapter<T : Any, VH : RecyclerView.ViewHolder>(
open var items: List = emptyList()
) : RecyclerView.Adapter() {
}

Research direction
Start by inspecting the BaseQuickAdapter declaration and its RecyclerView.Adapter inheritance. Check how lifecycle callbacks such as onViewAttachedToWindow and onViewRecycled currently receive holders. Done means the adapter accepts the VH generic and those callbacks can use the typed holder without a cast; no test file is mentioned in the issue.
