Fixes #3
Added additional support for any color instead of just one.

Question: Should there be a flag to enable this particular feature or just check the nullability of resource value?


styler.overlayColor()?.let {
check(context is Activity) { "Activity context is required in order to add an overlay view" }
val container = (context.window.decorView as ViewGroup)

I think an activity context isn't needed. Does anchor.rootView work here?

anchor.rootView does work.

styler.overlayColor()?.let {
check(context is Activity) { "Activity context is required in order to add an overlay view" }
val container = (context.window.decorView as ViewGroup)
val overlay = View(context, null, 0).apply {

Let's use the single param constructor?

container.addView(overlay)

val alphaInAnimator = ObjectAnimator.ofFloat(overlay, View.ALPHA, 1f).apply {
duration = 500

It's important to sync these two animations here PopupWindow's transition. See popup.enterTransition and popup.exitTransition and reuse their duration and interpolator?

enterTransition & exitTransition are only available from Nougat. Have added default fallback values for animation properties.

alphaInAnimator.start()

popup.setOnDismissListener {
val alphaOutAnimator = ObjectAnimator.ofFloat(overlay, View.ALPHA, 0f)

Any reason for not using overlay.animate().alpha(0f) instead of an ObjectAnimator?

val menuTitle: (MenuHeaderViewHolder) -> Unit = {},
val menuItem: (MenuItemViewHolder) -> Unit = {}
val menuItem: (MenuItemViewHolder) -> Unit = {},
val overlayColor: () -> Int? = { null }

Hmmmm a nullable Int looks good to me 👍. I'd suggest two things:

  • Rename overlayColor to backgroundDimColor.
  • Remove the lambda type. A color integer doesn't need to be lazily evaluated. It was necessary for the background Drawable to ensure a new instance is created on each lambda call because Drawables contain shared mutable state.

Potentially should be fixed in #45
