title: Xamarin.Forms Listview does not show selection ripple effect
body: <p>I'm working on a Xamarin.Forms project (for Android only at the moment).
  I found a lot of questions where people want to remove the ripple effect:
  See for example :</p>
  
  <ul>
  <li><a href="https://stackoverflow.com/questions/35586243/xamarin-forms-untappable-listview-remove-selection-ripple-effect?rq=1">Xamarin.Forms untappable ListView (remove selection ripple effect)</a></li>
  <li><a href="https://stackoverflow.com/questions/45085732/how-to-get-rid-of-the-listview-ripple-effect-in-xamarin-forms">How to get rid of the listview ripple effect in Xamarin.Forms</a></li>
  </ul>
  
  <p>But in my case, the ListView Viewcells does <strong>not</strong> show that effect on selection. I've already verified it has no background color. I want that effect when the user taps a Viewcell. The thing is that it works in another project I made, but I can't figure out why it does not here.</p>
  
  <p>My questions:</p>
  
  <ul>
  <li>Is this effect native in Android (API 25 on the device)</li>
  <li>For what reason(s) could it not be present when touching the cells ?</li>
  </ul>
  
  <p>My Listview XAML:</p>
  
  <pre><code>&lt;ListView ItemsSource="{Binding PickingParts}"
            SeparatorVisibility="None"
            SeparatorColor="Transparent"
            RowHeight="100"
            SelectedItem="{Binding SelectedPickingPart, Mode=TwoWay}"&gt;
  
      &lt;ListView.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;ViewCell&gt;
                  &lt;local:PickingPartItemTemplate /&gt;
              &lt;/ViewCell&gt;
          &lt;/DataTemplate&gt;
      &lt;/ListView.ItemTemplate&gt;
  
  &lt;/ListView&gt;
  </code></pre>
  
  <p>And the ItemTemplate:</p>
  
  <pre><code>&lt;ContentView xmlns="http://xamarin.com/schemas/2014/forms"
