                   IndicatorBackground="#E3F2FD" IndicatorPlacement="Fill" 
                   TabBarPlacement="Bottom">
   <tabView:TabItemCollection>
       <tabView:SfTabItem Header="Library">

           <Label Text="Browse Content" HorizontalOptions="Center" VerticalOptions="Center"/>
       </tabView:SfTabItem>

           <Label Text="Playlist Content" HorizontalOptions="Center" VerticalOptions="Center"/>
       </tabView:SfTabItem>
   </tabView:TabItemCollection>
