My two cents function without recursion

    package io.chord.ui.utils

import android.view.View
import android.view.ViewGroup
import androidx.core.view.forEach

class ViewUtils
{
    companion object
    {
        fun setViewState(view: View, state: Boolean)
        {
            var depth = 0
            val views: MutableMap> = mutableMapOf()
            views[depth] = mutableListOf(view)

            while(true)
            {
                val currentViews = views[depth]
                val nextViews = mutableListOf()

                currentViews!!.forEach { view ->
                    if(view is ViewGroup)
                    {
                        view.forEach { children ->
                            nextViews.add(children)
                        }
                    }
                }

                if(nextViews.size == 0)
                {
                    break
                }

                depth++

                views[depth] = nextViews
            }

            views.flatMap {
                it.value
            }.forEach {
                it.isEnabled = state
            }
        }
    }
}
