描述

Description

I've implemented an effect to capture touch events on a CollectionView, however, the MotionEvent ACTION_DOWN doesn't seem to be captured on Android. The MotionEvent ACTION_MOVE is properly being captured. I've tested this effect on other views with no issues. I've followed this link for creating the effect.

Steps to Reproduce

Touch down on CollectionView, without sliding.

Expected Behavior

Should fire the view's Touch event

Actual Behavior

Touch event is not fired on ACTION_DOWN
