问题 I'm looking for a way to style the color of the over scroll indicator in a RecyclerView pre-lollip when using the appcompat material theme. Internally it uses an EdgeEffect set to a internal styleable attribute that can't be set unless your already on lollipop (ironic).

问题 I am trying to find a way to implement a standing table for a sports app (like NBA Game Time standings), with a fixed header, fixed first column and a footer. I searched a bit on how to get it, but the best shot was this project (https://github.com/InQBarna/TableFixHeaders) but it uses its own view instead of Recycler of GridView.

问题 I've started getting this crash reported on Crashlytics. I have no idea how to reproduce it but it all appears to be code internal to the RecyclerView . I think this comes from a RecyclerView I have which never really changes. The user can refresh it but then all items are replaced and notifyDataSetChanged is called. java.lang.IndexOutOfBoundsException: Inconsistency detected.
