RecyclerView Kotlin onClickListener

Ejemplo de como integrar un recyclerview usando Kotlin, los elementos se mostrarán con filas simples y permite ser pulsados

Partiendo del trozo de código anterior (Recyclerview Kotlin I)[https://gist.github.com/webserveis/b66149f204c5946a8dd9107278486c63]

Añadir funcionalidad onClickListener

Para implementar onClickListener a los elementos que se visualizan en el recyclerView

MainActivity.kt

val mAdapter = MySimpleAdapter(dummyData())
recycler_view.setHasFixedSize(true)
recycler_view.layoutManager = LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
recycler_view.adapter = mAdapter

mAdapter.setOnItemClickListener(object : MySimpleAdapter.ClickListener {
    override fun onItemClick(v: View, position: Int) {

        Log.v(TAG, "onItemClick ${position}")

        Toast.makeText(
            this@MainActivity,
            "Clicked: ${mAdapter.getItem(position)}",
            Toast.LENGTH_SHORT
        ).show()
    }

})

MySimpleAdapter.kt

import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.TextView
import androidx.recyclerview.widget.RecyclerView

class MySimpleAdapter(private val mDataSet: List<String>?) :
    RecyclerView.Adapter<MySimpleAdapter.MyViewHolder>() {

    private var clickListener: ClickListener? = null

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val v = LayoutInflater.from(parent.context)
            .inflate(R.layout.simple_list_item_1, parent, false)
        return MyViewHolder(v)
    }

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val data = mDataSet?.get(position)
        data?.let { holder.bindItems(it) }
    }

    override fun getItemCount(): Int {
        return mDataSet?.size ?: 0
    }

    fun getItem(position: Int): String? {
        //return if (mDataSet != null) mDataSet[position] else null
        return mDataSet?.get(position)
    }

    fun setOnItemClickListener(clickListener: ClickListener) {
        this.clickListener = clickListener
    }


    inner class MyViewHolder(v: View) : RecyclerView.ViewHolder(v), View.OnClickListener {

        private val text1 = v.findViewById(android.R.id.text1) as TextView

        init {
            if (clickListener != null) {
                itemView.setOnClickListener(this)
            }
        }

        fun bindItems(data: String) {
            text1.text = data
        }

        override fun onClick(v: View?) {
            if (v != null) {
                clickListener?.onItemClick(v,adapterPosition)
            }
        }

    }

    interface ClickListener {
        fun onItemClick(v: View,position: Int)
    }
}

Boa noite. Será que vc poderia me ajudar. Eu não consigo capturar o clique correto do meu recycler. Ele captura todo o recycler, e não o item específico.

segue o codigo. Obrigado

class AdapterAvisos(val listaDeAvisos: ArrayList, val onClickListener: OnClickListener) : RecyclerView.Adapter<AdapterAvisos.MH>(){

class OnClickListener(val clickListener: (aviso: AV) -> Unit){
    fun onClick(tipo: AV) = clickListener(tipo)
}

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MH {
        val view = LayoutInflater.from(parent.context).inflate(R.layout.layout_avisos_modelo, parent, false)
            return MH(view)
    }

@SuppressLint("SuspiciousIndentation")
override fun onBindViewHolder(holder: MH, position: Int) {
val aviso = listaDeAvisos[position]
holder.tituloAviso.setText(aviso.titulo)
holder.autorAviso.setText(aviso.autor)
holder.mensagemAviso.setText(aviso.mensagem)
holder.dataAviso.setText(aviso.data)
holder.tipoAviso.setText(aviso.tipo)
//capturando o clique

                holder.tituloAviso.setOnClickListener {onClickListener.onClick(aviso)}
    }

    override fun getItemCount(): Int {
        return listaDeAvisos.size
    }

//View Holder
class MH(itemView: View) : RecyclerView.ViewHolder(itemView){
val tituloAviso: TextView = itemView.findViewById(R.id.txtTituloAvisoModelo)
val autorAviso: TextView = itemView.findViewById(R.id.txtAutorAvisoModelo)
val mensagemAviso: TextView = itemView.findViewById(R.id.txtMensagemAvisoModelo)
val dataAviso: TextView = itemView.findViewById(R.id.txtDataAvisoModelo)
val tipoAviso: TextView = itemView.findViewById(R.id.txtTipo)
}
}
eu quero que exiba o titulo do aviso quando o usuario clicar sobre um item do recycler.
