Thank you for writing.
I added 100 items to the list of cities created in the online documentation example and successfully reordered a lot of items including the first to position 50, but I was not able to reproduce an exception. Could you please give more detailed information about the reproduction steps? It would be best if you create a project that demonstrates the issue and send it to us.
As to the scroll speed... which speed exactly you would like to modify? The speed when you scroll through the list, the speed when a fling gesture occurs, or the scroll speed of the list while in reorder. The first is managed by the layout manager, the second by the recycler view and the third by the ItemReorderBehavior
. The last can't be modified with the current implementation, but we can add such a possibility if requested. For the others you need to either extend the layout manager that you are using (for the scroll speed) or RadListView
(for the fling speed).
