1.xml文件中添加ListView

<ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/data_list"
        android:divider="@color/colorPrimary"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/button_home"/>

2.声明adapter

package com.example.myapplication.ui.adapter

import android.content.Context
import android.view.View
import android.view.ViewGroup
import android.widget.BaseAdapter
import android.widget.ImageView
import android.widget.TextView
import com.example.myapplication.R

class DataListDataAdapter(var context:Context?,var dataList: MutableList<String>) : BaseAdapter() {


    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
        val holder:ViewHolder;
        val layout:View
        if (convertView==null) {
            holder = ViewHolder()
            layout = View.inflate(context,R.layout.list_item,null)
            holder.iconInfo = layout.findViewById(R.id.icon_info)
            holder.textInfo = layout.findViewById(R.id.text_info)
            holder.textInfo!!.text = dataList[position]
            layout.tag = holder
        } else {
            layout = convertView
            holder = convertView.tag as ViewHolder
        }
        return layout
    }

    override fun getItem(position: Int): Any {
        return dataList[position]
    }

    override fun getItemId(position: Int): Long {
        return position.toLong()
    }

    override fun getCount(): Int {
        return dataList.size
    }

    inner class ViewHolder{
         var iconInfo: ImageView? = null
         var textInfo: TextView? = null
    }
}

3.item布局

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher"
        android:id="@+id/icon_info"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/text_info"
        android:text="Hello Kotlin"
        android:textSize="20sp"
        android:layout_marginStart="20dp"
        app:layout_constraintLeft_toRightOf="@+id/icon_info"
        app:layout_constraintTop_toTopOf="@+id/icon_info"
        app:layout_constraintBottom_toBottomOf="@+id/icon_info"/>

</androidx.constraintlayout.widget.ConstraintLayout>

4.ListView绑定数据

listView = root.findViewById(R.id.data_list)
        var list:MutableList<String> = mutableListOf()
        list.add("Hello")
        list.add("Kotlin")
        list.add("Come on")
        val adapter = DataListDataAdapter(context,list)
        listView.adapter = adapter
