Hi Mark,
I have a very simple recyclerView as shown below in the code,
The issue is that it does not respond to clicks (in this case it should just display a smiple snackbar), I’ve made sure that my cardView is set to clickable in the xml file.
I’ve also moved the code to the onBindViewHolder , but still no response to clicks.
I’m testing on API 29 Emulator.
I’ve looked at other examples and the only difference that I can see is that the some of the examples add an Interface , then implementing the interface in the activity or another class. but as far as the code below I’m not sure why it’s not working. no action in logcat either.

So I would like to ask:

  1. How can I make the items respond to clicks?
  2. How do you usually handle the clicks in a production app? Do you prefer using the Interface method?

Thanks again

class RecyclerAdapter(private var items: List<Result>) :
RecyclerView.Adapter<RecyclerAdapter.ViewHolder>() {

inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    val TAG: String = "View Holder"

    val itemTitle: TextView = itemView.findViewById(
    val itemDetail: TextView = itemView.findViewById(
    val itemPicture: ImageView = itemView.findViewById(

    init {
        itemView.setOnClickListener { v: View ->
            val position: Int = adapterPosition
            Snackbar.make(v, "You clicked on ${items[position].strEvent}", Snackbar.LENGTH_LONG)
                .setAction("Action", null).show()
            Log.d(TAG, ": clicked ${items[position].strEvent}")

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
    val v = LayoutInflater.from(parent.context).inflate(R.layout.recycler_item, parent, false)
    return ViewHolder(v)

override fun getItemCount(): Int {
    return items.size

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    holder.itemTitle.text = items[position].strEvent
    holder.itemDetail.text = items[position].strDescriptionEN

Off the cuff, what you have should work. Here are some examples from Elements of Android Jetpack that demonstrate clicks on RecyclerView rows:

You might want to compare and contrast your implementation with mine and see where they differ.

I would pass a function type into the ViewHolder that can be invoked on a click event.
