title: How to show Navigationbar 'TitleView' Common for all pages
body: <p>I have added <code>TitleView</code> in <code>MainPage</code> to show on <code>Navigationbar</code> but it shows only for <code>MainPage</code> when I navigate to some other page <code>Navigationbar</code> displaying empty.</p>
  
  <p>Below code I have in <strong><code>MainPage.xaml</code></strong> file</p>
  
  <pre><code>&lt;NavigationPage.TitleView&gt;
  &lt;RelativeLayout  HorizontalOptions="Fill" 
      &lt;Image Source="bell.png"  HeightRequest="25" WidthRequest="25" x:Name="imgBell"
             RelativeLayout.YConstraint="{ConstraintExpression
           Type=RelativeToParent,
           Property=Height,
           Factor=0.018,Constant=10}"&gt;
          &lt;Image.GestureRecognizers&gt;
              &lt;TapGestureRecognizer  Command="{Binding GetStaffAnnouncementCommand}"&gt;&lt;/TapGestureRecognizer&gt;
          &lt;/Image.GestureRecognizers&gt;
      &lt;/Image&gt;
  
          &lt;Label  FontSize="10" HorizontalTextAlignment="Center"  VerticalTextAlignment="Center"  BackgroundColor="Transparent" Text="2"    TextColor="Red"
                  HeightRequest="22" WidthRequest="23" x:Name="labelText"&gt;
      &lt;/Frame&gt;
  
  &lt;/RelativeLayout&gt;
  &lt;/NavigationPage.TitleView&gt;
