Hello,  
I have a code on Java. This is the code inside getView method of BaseAdapter.

viewHolder.button1 = (Button) convertView.findViewById(R.id.button1);  
viewHolder.button1.setOnClickListener(new OnClickListener() {

```
@Override
public void onClick(View v) {
    ((ListView) parent).performItemClick(v, position, 0); // Let the event be handled in onItemClick()
}

```

});  
So, the question is, how to cast parent (ViewGroup) to ListView in Kotlin?  
Thank you for your answers!

```kotlin
(parent as ListView).performClick(...)

```

Not working for you?
