Answer 1

Have you tried with this for ChangeContact?

 android:focusable="true"
 android:focusableInTouchMode="true"

also ChangeContact.requestFocus()?

Answer 2

In my case I can't get on focus change event because I forgot to delete setContentView() function and used it with binding initialization like this:

 setContentView(R.layout.activity_main)
    
 binding = ActivityMainBinding.inflate(layoutInflater, null, false)

also eventually I understood that binding initialization also was incorrect
