我正在尝试为我的 Windows Phone Silverlight 应用程序创建一个应用程序栏。我已经多次检查过这段代码。我看没有错误。即使我检查了 MSDN 的网站。但是当我在模拟器上运行它时,应用程序栏没有显示。
我的代码有什么问题?
<phone:PhoneApplicationPage.ApplicationBar>
<shell:ApplicationBar Mode="Default" Opacity="1.0" IsVisible="True" IsMenuEnabled="True">
<shell:ApplicationBarIconButton IconUri="/Assets/ApplicationBar/next.png" Text="Next" Click="appBar_next"/>
<shell:ApplicationBar.MenuItems>
</shell:ApplicationBar.MenuItems>
</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>
这是完整的 XAML 代码:
