InboxRecyclerView applies soft dimming on the list when it's covered by ExpandablePageLayout. The dimming is shifted to the page when it's pulled past the collapse threshold, as a visual indication that the page can now be released.
By default, a black dim with an alpha of 15% is applied on the list. This can be customized by using,
recyclerView.dimPainter = DimPainter.listAndPage(color = Color.WHITE, alpha = 0.65F)If you wish to only apply dimming on the list, DimPainter.listOnly(...) can be used.
It’s also encouraged that apps find other creative ways of communicating this to the user. Dank, for example, uses the status bar color to indicate when the content is eligible for collapse.
