React-Native Android ScrollView can't get event from onScroll

Question

If there is only one item or few items in ScrollView on Android, I won't get any event from onScorll. In iOS, I still could get the event because the bounces.

My problem is how could I listen to the scroll offset on Android with a list? I've tried PanResponder, but in my case, I would like to detect the swipe down and up gesture in a vertical Flatlist.

Answer 1

Flatlist is built internally using the responder API, so if it doesn't do exactly what you want then you definitely can use PanResponder.

If there is only a few items in your data array then the list can't scroll, so no scroll will be triggered.

If you are just trying to track a swipe gesture for example do dismiss something, that isn't really what Flatlist was designed to solve, and you could use PanResponder directly.
