Xamarin.forms android listviewrenderer

I want to use a onscroll-listener for listview, as far i know this isn't buildin in xamarin.forms.ListView. So using a renderer is logic solution till I saw Xamarin.Forms.Android doesn't have a ListViewRenderer yet.. IOS does,

What are the alternatives? How can I implement a scroll listener or get the first visible view in a other way?
Thnx!
