Android – Architecture – How to commonize/ customize Android view for frequent use in entire application?

Create file including custom Views

import android.view.View

fun View.gone() {
    visibility = View.GONE
}

fun View.visible() {
    visibility = View.VISIBLE

fun View.isVisible(): Boolean = visibility == View.VISIBLE
