title: Xamarin.Forms ListView: Set the highlight color of a tapped item
body: <p>Using <em>Xamarin.Forms</em>, how can I define the highlight/background color of a selected/tapped ListView item?</p>
  
  <p>(My list has a black background and white text color, so the default highlight color on iOS is too bright. In contrast, on Android there is no highlighting at all - up to a subtle horizontal gray line.)</p>
  
  <p><strong>Example:</strong> (left: iOS, right: Android; while pressing "Barn2")</p>
