Navigation Architecture Component - Action Navigation with lambda expression

Replace the brackets after .setOnClickListenerwith parentheses

 view.findViewById<Button>(R.id.navigate_action_bt)?.setOnClickListener {
    Navigation.createNavigateOnClickListener(R.id.go_to_step_one, null)
}

 view.findViewById<Button>(R.id.navigate_action_bt)?.setOnClickListener(
    Navigation.createNavigateOnClickListener(R.id.go_to_step_one, null)
)

Well, that's the proper way of working. The method Navigation.createNavigateOnClickListener() returns a View.OnClickListener and according to the docs the proper way of assiging it is by using, even in Kotlin:

button.setOnClickListener(Navigation.createNavigateOnClickListener(R.id.next_fragment, null));

If you using the method inside the lambda, the lambda itself is the click listener so you're returning a click listener inside the click listener, that's why it isn't working. It's like doing this:

button.setOnClickListener {
            View.OnClickListener {
                Toast.makeText(this, "hi", Toast.LENGTH_LONG).show()
            }
        }

What you might be intrested in is this:

 view.findViewById<Button>(R.id.navigate_action_bt)?.setOnClickListener { view ->
   view.findNavController().navigate(R.id.go_to_step_one)
}

Which will perform the navigation transition on button click.
