Prevent views from being clicked until animation added to action via navigation component completes

Question

Given 2 Fragments A and B, A moves to B (so A -> B), via navigation component action with enter animation has been added. How to prevent views in Fragment B being clickable while enter animation is running? I've found this question How to add listener to android Navigation Architecture Component action animation but unfortunately there're no answers.

What I found in the documentation is that I could get resource ID of that animation through NavOptions object hooked onto the NavAction, but not the Animation object itself.

You can start by having your views as disabled in xml android:enabled="false" then in your fragment's onViewCreated you can set a delay with the animation duration using coroutines:

override fun onViewCreated(view: View, savedState: Bundle?) {
    super.onViewCreated(view, savedState)

    // Initialize views here. 


    lifecycleScope.launch {
        delay(resources.getInteger(R.integer.anim_duration).toLong())
        // Enable views here
        myView.isEnabled = true
    }
}
