Listview scrolling getting stuck while I am using relative layout in viewcell. Earlier it was working fine, but I think because of updating nuget packages or Xamarin studio, this issue arised. (In Android)
Now while scrolling very first time in this case, Scrolling get stuck after some time it scrolls smooth.
Alternatively If i use Stack layout instead of relative layout, listview scrolls smooth, But i need relative layout.

## Note to the Xamarin team
This sounds potentially related to Bug 56240? Perhaps once candidate builds are available that resolve Bug 56240, it would be good to have the reporter of this Bug 56562 check if those builds resolve this issue as well.
I've noticed the same issue. The RelativeLayout performance in a custom ViewCell of a ListView is virtually unusable on Android, but fine in iOS.
I already started writing up a ticket before I found this one, so I'm including my sample project as a 2nd data point.

RelativeLayout Perf Issue Sample Project
In XfRelativeLayoutIssue\MainPage.cs it uses a RelativeLayout in a custom ViewCell of a ListView. When you run this on Android (API 22 anyway) the performance is virtually unusable.
I've tested both
And it seems the performance is fine. I believe based on the fix in https://bugzilla.xamarin.com/show_bug.cgi?id=56562#c2 that has resolved this issue. Thus I am marking this bug as a DUPLICATE of https://bugzilla.xamarin.com/show_bug.cgi?id=56240
