ArrayAdapter- Getview() causes an error

I have a little problem I couldn't solve. I've searched and I tried a lot of things, Unfortunately no results. Getview is causing an error

The line causnig an error is this one below in ArrayAdapter:

val tvCopiedText:TextView = view!!.findViewById(R.id.tv_copiedText)

Here is the code:

ArrayAdapter

class MyArrayAdapter: ArrayAdapter<CopiedText> {
constructor(context: Context, resource:Int, copiedTexts: List<CopiedText>) : super(context, resource, copiedTexts) {
}

override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
    var view: View? = null
    val copiedText:CopiedText = getItem(position)
    if (convertView == null){
        view = LayoutInflater.from(context).inflate(R.layout.item_layout, parent, false)

    }

    val tvCopiedText:TextView = view!!.findViewById<TextView>(R.id.tv_copiedText)
    val tvTime:TextView = view.findViewById<TextView>(R.id.tv_time)
    //val tvCopiedText = retView!!.findViewById<TextView>(R.id.tv_copiedText)
    //val tvCopiedText = retView!!.findViewById<TextView>(R.id.tv_copiedText)

    tvCopiedText.text = copiedText.ctText
    tvTime.text = copiedText.ctTime.toString()

    return  view
}

}

Adapter in MainActivity:

ctAdapter = MyArrayAdapter(this, R.layout.item_layout, listCopiedText)
    myListView.adapter = ctAdapter

item_layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:paddingBottom="8dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:paddingTop="8dp"
    >

    <TextView
        android:id="@+id/tv_copiedText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:textSize="14sp"
        tools:text="Here will be the copied Text" />

    <TextView
        android:id="@+id/tv_time"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="14sp"
        tools:text="Time"/>

The reason why you are getting a null pointer is because you are not assigning the view variable to anything in case convertView is not null. Change this code

var view: View? = null
    val copiedText:CopiedText = getItem(position)
    if (convertView == null){
        view = LayoutInflater.from(context).inflate(R.layout.item_layout, parent, false)

    }

to

var view: View? = convertView
    val copiedText:CopiedText = getItem(position)
    if (view == null){
        view = LayoutInflater.from(context).inflate(R.layout.item_layout, parent, false)

    }
