Description

It seems I can't disable scrolling for a ListView on Android, or disable its overscroll effect (similar to overScrollMode for a ScrollView). For iOS, I can simly set "canScroll" to false. Please add this feature to Android as well. Thanks.

Hello [~shawnlan], you can use "touchEnabled = false" for Android to disable ListView scroll. But, remember it will make you lose the itemclick event possibility. Thanks.

I will need itemclick event. Most people will need it as well. Please add the canScroll to Android. I don't see a reason why it's on iOS but not on Android. Thanks.
