Description
Version used: 26.0.1
Theme used: Theme.AppCompat.Light.DarkActionBar
Devices/Android versions reproduced on: Motorola X Play (API 23), Pixel AVD (Android 8), OnePlus5 (API 24/25)
- Relevant code to trigger the issue : use the sample app attached
- A screenrecord or screenshots showing the issue (if UI related).
To reproduce : start the ClickNotWorking app, scroll to the last item (bottom of the screen), then scroll/fling as if you wanted to see more data below (but you have already reached the bottom of the list), and try to click on a item quickly after that. You won't see the ripple effect, neither the "CLICK" in the logcat. But if you try to click a second time, it is working.
The first click seems to stop an invisible fling effect....
This bug does not appear with the support version 26.0.0-alpha1 and 26.0.0-beta1. It appears from the release 26.0.0 to the 26.0.1.
It seems to be associated to the NestedScrollingChild2 interface. With alpha and beta version, RecyclerView was implementing the NestedScrollingChild interface, and starting from 26.0.0 release, it is implementing NestedScrollingChild2 interface.
