You can get the ListView from the item of ListView by iterating View's parent till we get the ListView.

public partial class MyItemView : ContentView, INotifyPropertyChanged
{
    ListView listView;

    protected override void LayoutChildren(double x, double y, double width, double height)
    {
        base.LayoutChildren(x, y, width, height);

        Element list = this;

        while(list.GetType() != typeof(ListView))
        {
            list = list.Parent;
        }

        listView = list as ListView;
    }
}
