holder.itemView.rowLayout.setOnClickListener

Question

I have created the following adapter class for recyclerview but there is a compilation error while building in layout section "holder.itemView.rowLayout.setOnClickListener" Unresolved reference: rowLayout, I have changed the layout to LinearLayout aswell but still there is compilation error The following is the Adapter class and customRow.XML respectively,

package com.example.roomapp.fragments.list

import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.navigation.findNavController
import androidx.recyclerview.widget.RecyclerView
import com.example.roomapp.R
import com.example.roomapp.model.User
import kotlinx.android.synthetic.main.custom_row.view.*

class ListAdapter: RecyclerView.Adapter<ListAdapter.MyViewHolder>() {

    private var userList = emptyList<User>()

    class MyViewHolder(itemView: View): RecyclerView.ViewHolder(itemView) {}

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

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

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val currentItem = userList[position]
        holder.itemView.id_txt.text = currentItem.id.toString()
        holder.itemView.txfirstName.text = currentItem.firstName
        holder.itemView.txlastName.text = currentItem.lastName
        holder.itemView.txContactNo.text = currentItem.contactNumber.toString()
        holder.itemView.txEmailAddress.text = currentItem.email.toString()

        holder.itemView.rowLayout.setOnClickListener {
            val action = ListFragmentDirections.actionListFragmentToUpdateFragment(currentItem)
            holder.itemView.findNavController().navigate(action)
        }
    }

    fun setData(user: List<User>){
        this.userList = user
        notifyDataSetChanged()
    }
}

    </LinearLayout>

Answer 1

There is no rowLayout in the xml.

But if you want an onclick on entire row, you can change

holder.itemView.rowLayout.setOnClickListener {
            val action = ListFragmentDirections.actionListFragmentToUpdateFragment(currentItem)
            holder.itemView.findNavController().navigate(action)
        }

to

holder.itemView.setOnClickListener {
            val action = ListFragmentDirections.actionListFragmentToUpdateFragment(currentItem)
            holder.itemView.findNavController().navigate(action)
        }
