fun View.margin(left: Float? = null, top: Float? = null, right: Float? = null, bottom: Float? = null) {
    layoutParams<ViewGroup.MarginLayoutParams> {
        left?.run { leftMargin = dpToPx(this) }
        top?.run { topMargin = dpToPx(this) }
        right?.run { rightMargin = dpToPx(this) }
        bottom?.run { bottomMargin = dpToPx(this) }

inline fun <reified T : ViewGroup.LayoutParams> View.layoutParams(block: T.() -> Unit) {
    if (layoutParams is T) block(layoutParams as T)
