我对默认的应用程序栏做了非常小的修改,但是当我运行代码时,它只是显示为一个灰色框。这是 XAML:
<phone:PhoneApplicationPage
x:Class="IHeartWords.MainPage"

<!--Sample code showing usage of ApplicationBar-->
<phone:PhoneApplicationPage.ApplicationBar>
<shell:ApplicationBar IsVisible="True" IsMenuEnabled="False">
<shell:ApplicationBarIconButton x:Name="help" IconUri="/icons/appbar.questionmark.rest.png" Text="Help" Click="helpButton_Click"/>
<shell:ApplicationBarIconButton x:Name="rules" IconUri="/icons/appbar.feature.settings.rest.png" Text="Rules" Click="rulesButton_Click"/>
</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>
</phone:PhoneApplicationPage>
