在Android中用Kotlin实现RecyclerViewAdapter自定义接口

interface OnItemClickListener {
    fun onItemClick(position: Int)
}

private var onItemClickListener: OnItemClickListener? = null

class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    init {
        itemView.setOnClickListener {
            val position = adapterPosition
            onItemClickListener?.onItemClick(position)
        }
    }
}

fun setOnItemClickListener(listener: OnItemClickListener) {
    this.onItemClickListener = listener
}

val adapter = MyAdapter(data)
adapter.setOnItemClickListener(object : OnItemClickListener {
    override fun onItemClick(position: Int) {
        // 处理项点击事件
    }
})
