一个万能的RecyclerView adapter，轻松实现多itemViewType界面

第一步：创建dto、holder（有几个itemViewType就创建几组 dto & holder）

    class ADto(s: String) : BaseDto<String>(s) {
    }

    class AHolder(itemView: View, adapter: RecyclerView.Adapter<*>) :
        BaseHolder<ADto>(itemView, adapter) {
        var binding: ItemABinding = ItemABinding.bind(holderView)
        override fun setData(data: BaseDto<*>) {
            val dto: ADto = data as ADto
            binding.tvNumber.text = dto.data
        }
    }
    class BDto(s: String) : BaseDto<String>(s) {
    }

    class BHolder(itemView: View, adapter: RecyclerView.Adapter<*>) :
        BaseHolder<BDto>(itemView, adapter) {
        var binding: ItemBBinding = ItemBBinding.bind(holderView)
        override fun setData(data: BaseDto<*>) {
            val dto: BDto = data as BDto
            binding.tvNumber.text = dto.data
        }
    }

第二步：创建adapter

    var mAdapter: BaseAdapter
    mAdapter = BaseAdapter(
            this, listOf(
                DtoStyle(ADto::class, R.layout.item_a, AHolder::class),
                DtoStyle(BDto::class, R.layout.item_b, BHolder::class)
        )
    )
    binding.recyclerView.adapter = mAdapter

第三步：update

    mAdapter.update(
        listOf(
            ADto("this is item A"),
            BDto("this is item B"),
            ADto("this is item A"),
            BDto("this is item B"),
            ADto("this is item A"),
            ADto("this is item A"),
            BDto("this is item B"),
            BDto("this is item B"),
        )
    )
