ListView change background color for selected items ( Xamarin - Android )

Issue:
How to change  background color for all selected items in Android


Fix: ( Xamarin  - c# syntax - Android should work with little change)
  
  myListView.ItemClick +=(sender, e) => {
                myListView.GetChildAt( e.Position).SetBackgroundColor( Color.White);
               
            };

This will show the color change on all selected items. If you use myListView_ItemSlected event -> The color only shows like a highlight and when you select the next item the background color changes back to default.
