请问MultiType与AsyncListDiffer如何结合使用

[liukepeng]

如题

如下

class ConvAdapter : MultiTypeAdapter() {
private val asyncListDiffer: AsyncListDiffer = AsyncListDiffer(this,
object : DiffUtil.ItemCallback() {
override fun areItemsTheSame(oldItem: Any, newItem: Any): Boolean {
if (oldItem is ConvBean && newItem is ConvBean)
return oldItem.peerUser.uid == newItem.peerUser.uid
return false
}

        override fun areContentsTheSame(oldItem: Any, newItem: Any): Boolean {
            return if (oldItem is ConvBean && newItem is ConvBean) oldItem == newItem
            else if (oldItem::class == newItem::class) true
            else false
        }
    })

fun submitList(list: List<Any>) {
    items = list
    asyncListDiffer.submitList(list)
}

}
