Add addOnItemClickListener easily to a RecyclerView using Kotlin

RecyclerViewExtension.kt

import android.support.v7.widget.RecyclerView
import android.view.View

interface OnItemClickListener {
    fun onItemClicked(position: Int, view: View)
}

fun RecyclerView.addOnItemClickListener(onClickListener: OnItemClickListener) {
    this.addOnChildAttachStateChangeListener(object: RecyclerView.OnChildAttachStateChangeListener {
        override fun onChildViewDetachedFromWindow(view: View?) {
            view?.setOnClickListener(null)
        }

        override fun onChildViewAttachedToWindow(view: View?) {
            view?.setOnClickListener({
                val holder = getChildViewHolder(view)
                onClickListener.onItemClicked(holder.adapterPosition, view)
            })
        }
    })
}

// Usage:
recyclerView.addOnItemClickListener(object: OnItemClickListener {
    override fun onItemClicked(position: Int, view: View) {
        // Your logic
    }
})
