c# - 如何更改 UWP 中 ListBoxItem 的选择突出显示颜色？

Question

我想更改 ListBoxItem 的选择突出显示颜色

左侧的 Split View Pane 有一个包含 ListBoxItems 的列表框。默认选择颜色是蓝色，我想自定义它但我无法更改它。

我找不到任何属性来更改 UWP 中 ListBoxItem 的选择突出显示颜色。

你可以改变ListBoxItem的style来改变选择的高亮颜色。在style中，你应该改变所有包含'Selected'关键字的状态来改变将 Fill 属性设置为您想要的颜色(我将颜色更改为红色，如下所示)。

<Style x:Key="ListBoxItemStyle1" TargetType="ListBoxItem">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="TabNavigation" Value="Local"/>
    <Setter Property="Padding" Value="{StaticResource ListBoxItemPadding}"/>
    <Setter Property="HorizontalContentAlignment" Value="Left"/>
    <Setter Property="UseSystemFocusVisuals" Value="{StaticResource UseSystemFocusVisuals}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ListBoxItem">
                <Grid x:Name="LayoutRoot" Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}">
                    <Grid.Resources>
                        <Style x:Key="BaseContentPresenterStyle" TargetType="ContentPresenter">
                            <Setter Property="FontFamily" Value="XamlAutoFontFamily"/>
                            <Setter Property="FontWeight" Value="SemiBold"/>
                            <Setter Property="TextWrapping" Value="Wrap"/>
                            <Setter Property="LineStackingStrategy" Value="MaxHeight"/>
                            <Setter Property="TextLineBounds" Value="Full"/>
                            <Setter Property="OpticalMarginAlignment" Value="TrimSideBearings"/>
                        </Style>
                        <Style x:Key="BodyContentPresenterStyle" BasedOn="{StaticResource BaseContentPresenterStyle}" TargetType="ContentPresenter">
                            <Setter Property="FontWeight" Value="Normal"/>
                        </Style>
                    </Grid.Resources>
                    <VisualStateManager.VisualStateGroups>

                                        <DiscreteObjectKeyFrame KeyTime="0" Value="Red"/>

                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                    <Rectangle x:Name="PressedBackground" Fill="Transparent" Control.IsTemplateFocusTarget="True"/>
                    <ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Style="{StaticResource BodyContentPresenterStyle}" TextWrapping="NoWrap" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后给ListBox设置样式。

<ListBox Width="100" ItemContainerStyle="{StaticResource ListBoxItemStyle1}">
