Kotlin 未解决参考：inflate

Question

i was learning how to make recycler view in kotlin, and given code like this for my adapter

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
        return when (viewType) {
            ITEM_HEADER -> MenuHeaderHolder(parent.inflate(R.layout.item_header))
            ITEM_MENU -> MenuItemHolder(parent.inflate(R.layout.item_menu))
            else -> throw throw IllegalArgumentException("Undefined view type")
        }
    }

and my Class MenuHeaderHolder

class MenuHeaderHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    private val itemHeader = itemView.findViewById(R.id.tvHeaderItem) as TextView

    fun bindContent(text: String){
        itemHeader.text = text
    }
}

but i get error unresolved reference: inflate, how fox this?

Answer 1

Try the following instead,

       val inflater = LayoutInflater.from(parent.context)
        return when (viewType) {
            ITEM_HEADER -> MenuHeaderHolder(inflater.inflate(R.layout.item_header,parent,false))
            ITEM_MENU -> MenuItemHolder(inflater.inflate(R.layout.item_menu,parent,false))
            else -> throw throw IllegalArgumentException("Undefined view type")
        }
