Kotlin and Android Development featuring Jetpack: Ch. 9 won't build

The setClickListener function is an extra binding adapter on the ViewBindingAdapter class, so you would need an additional import there. That being said, I think that signature may have changed as well.

In reality, the better approach here is to use the setOnClickListener { ... } function on the view’s root:

root.setOnClickListener {
  ...
}

This is clearer and similar to how you normally handle click listeners in Android.
