How to do it...

1. Call the setOnClickListener function and pass an empty OnClickListener instance as a lambda expression:

class RegistrationScreen : Activity() {    private val submitButton: Button by lazy { findViewById(R.id.submit_button) }      override fun onCreate(savedInstanceState: Bundle?) {        submitButton.setOnClickListener { view: View ->            // do something on click        }    }}

2. Modify the visibility of the submitButton instance inside the function body:

class RegistrationScreen : Activity() {    private val submitButton: Button by lazy { findViewById(R.id.submit_button) }      override fun onCreate(savedInstanceState: Bundle?) {        submitButton.setOnClickListener {            submitButton.visibility = View.INVISIBLE        }    }}
