holder.itemView.rowLayout.setOnClickListener

Question

我已经为 recyclerview 创建了以下适配器 class 但是在布局部分构建时出现编译错误 "holder.itemView.rowLayout.setOnClickListener" 未解决的参考：rowLayout ，我也将布局更改为 LinearLayout 但仍然存在编译错误下面分别是Adapterclass和customRow.XML，

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()
    }
}

customRow.XML

    </LinearLayout>

</androidx.cardview.widget.CardView>

Answer 1

xml 中没有 rowLayout。

但是如果你想点击整行，你可以改变

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

至

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

holder.itemView.rowLayout.setOnClickListener

holder.itemView.rowLayout.setOnClickListener
