我的UWP应用具有导航视图，并在标题栏中使用带有扩展丙烯酸的Fluent Design。因此，您必须自己绘制应用程序标题，通常使用CaptionTextBlockStyle使用TextBlock控件自动显示在标题栏中。我尝试应用Microsoft here提供的示例但不幸的是，此示例未考虑标题栏中的扩展丙烯酸。在修改后的XAML代码下面：

结果是应用程序的标题显示在左上角，但出现在通常不应该存在的标题栏中。如何获得与“日历”应用相同的结果？感谢您的帮助。
[NavigationView是集成的组合控件，如果要在TextBlock上添加PaneToggleButton，则只能修改NavigationView的模板。

xaml.cs
public MainPage()
{
this.InitializeComponent();
var coreTitleBar = CoreApplication.GetCurrentView().TitleBar;
coreTitleBar.ExtendViewIntoTitleBar = true;
}
在名为PaneToggleButtonGrid的网格中，我们添加了TextBlock以显示应用程序标题。另外，我们需要添加一些状态影响。在<VisualStateGroup x:Name="PaneStateGroup">中，我们添加了控制AppTitle可见性和一些UI处理的代码。
BTW，如果您需要一些更复杂的效果，例如动态更改AppTitle的值，则可以尝试使用SplitView和Frame来构建自定义NavigationView以满足您的需求。
最诚挚的问候。
