UWP AppBarButton 前景色在不同的 Windows SDK 版本中不起作用

Question

我有一个正在开发的 Xamarin 应用程序。我们在 xaml 中有一个自定义样式模板，供我们的 AppBarButton 在 UWP 中使用。自定义样式适用于 Windows 10 Fall Creators Update SDK。但是当我们尝试更改为 Windows 10 版本 1803 或更高版本时，样式不再被接受或用于按钮。有谁知道您在 Xaml 中创建自定义模板以应用自定义样式的方式是否有任何变化？

这是我的 app.xaml

    <Application
        x:Class="ServicePro.UWP.App"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        RequestedTheme="Light">
        <Application.Resources>
            <ResourceDictionary>
                <ResourceDictionary.MergedDictionaries>
                    <ResourceDictionary Source="ServiceProResources.xaml" />
                    <ResourceDictionary Source="ms-appx:///Msi.CustomForms.UWP/Resources.xaml" />
                </ResourceDictionary.MergedDictionaries>
            </ResourceDictionary>
        </Application.Resources>
    </Application>

这是自定义资源目录。

Answer 1

事实证明，我并没有尝试设置正确元素的样式。

我需要在样式减速中添加x:key="AppBarButtonRevealStyle。然后元素从其获取样式的继承层次结构存在问题。

Answer 2

有谁知道您在 Xaml 中创建自定义模板以应用自定义样式的方式是否有任何变化？

您可以在 UWP 客户端应用程序中的 generic.xaml 文件中获取最新的 AppBarButton 样式。并且我已经和你提到的样式进行了比较，它将ContentRoot修改为网格面板等。请使用以下替换上述样式。

<Style TargetType="AppBarButton">
        <Setter Property="Background" Value="{ThemeResource AppBarButtonBackground}" />
        <Setter Property="Foreground" Value="{ThemeResource AppBarButtonForeground}" />
        <Setter Property="BorderBrush" Value="{ThemeResource AppBarButtonBorderBrush}" />
        <Setter Property="HorizontalAlignment" Value="Left" />
        <Setter Property="VerticalAlignment" Value="Top" />
        <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
        <Setter Property="FontWeight" Value="Normal" />
        <Setter Property="Width" Value="68" />
        <Setter Property="UseSystemFocusVisuals" Value="{StaticResource UseSystemFocusVisuals}" />
        <Setter Property="AllowFocusOnInteraction" Value="False" />
        <Setter Property="KeyboardAcceleratorPlacementMode" Value="Hidden" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="AppBarButton">
                    <Grid x:Name="Root"
                        MinWidth="{TemplateBinding MinWidth}"
                        MaxWidth="{TemplateBinding MaxWidth}"
                        Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}"
                        CornerRadius="{TemplateBinding CornerRadius}" >

                        <VisualStateManager.VisualStateGroups>
