So the way I fixed this in Kotlin is the following: (thanks to Simons post)

companion object {
    private val attributes = intArrayOf(
            android.R.attr.paddingLeft,
            android.R.attr.paddingTop,
            android.R.attr.paddingBottom,
            android.R.attr.paddingRight)
}

init {
    val arr = context.obtainStyledAttributes(attrs, attributes)

    @StyleableRes
    var i = 0

    val leftPadding = arr.getDimensionPixelOffset(i++, 0)
    val topPadding = arr.getDimensionPixelOffset(i++, 0)
    val rightPadding = arr.getDimensionPixelOffset(i++, 0)
    val bottomPadding = arr.getDimensionPixelOffset(i, 0)

    arr.recycle()
}
