How can I disable all views inside the layout?

Question

For example I have:

Answer 1

I personally use something like this (vertical tree traversal using recursion)

fun ViewGroup.deepForEach(function: View.() -> Unit) {
    this.forEach { child ->
        child.function()
        if (child is ViewGroup) {
            child.deepForEach(function)
        }
    }
}

usage :

   viewGroup.deepForEach { isEnabled = false }
