Crash if used in recyclerview. #18
Description
I have used Shuffle inside a recyclerview. App crashes when user trying to drag card. It is easy to repro.
- Add few elements in recyclerview. Keep one of them as Shuffle layout.
- Scroll to make Shuffle view inside view port.
- scroll back to make shuffle outside of view port.
4 Scroll again to make same shuffle view inside view port again. - Now try to drag a view.
App crashes with following stack.
