c# - 如何在 UWP 中更改 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

左侧的拆分视图窗格有一个包含 ListBoxItems 的 ListBox。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。

您可以更改ListBoxItem的样式Selected以更改选择突出显示颜色。在样式中，您应该更改所有包含 ' ' 关键字的状态以将 Fill 属性更改为您想要的颜色（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}">

                        <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"/>

                        </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>

然后将样式设置为 ListBox。

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

您可以自定义 的ListViewItem样式ListView，可以在 中找到generic.xaml，位于C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.18362.0\Generic\generic.xaml。路径可能不同，但您可以搜索。

在generic.xaml中，您可以看到所有控件的模板。然后搜索<Style TargetType="ListViewItem" x:Key="ListViewItemRevealStyle">，复制整个样式，并新建一个名为ListViewItem.xaml. 该文件应如下所示：

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

</ResourceDictionary>

在此文件搜索SelectedBackground中，如果要将背景更改为橙色，请输入 SelectedBackground="Orange"。另请注意另一个名为 的属性SelectedPointerOverBackground，您也可以根据需要更改值。

完成所有这些后，添加ListViewItem.xaml到App.xaml，以便应用程序可以识别您自己的风格。App.xaml应该是这样的：

<Application
    x:Class="App2.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App2">

    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="ListViewItem.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

然后将您的 ListView 项目样式更改为

<ListView ItemContainerStyle="{StaticResource ListViewItemRevealStyle}">

Bingo，按 F5 构建并运行。

上述步骤可能有点复杂，但值得。稍后您可能想要更改 TextBox 的样式或其他内容，您也可以按照本教程进行操作。

最简单的方法是给你的列表框设置皮肤是在 app.xaml 中定义相应的画笔，只需在你的 Application 元素中添加如下内容：

<Application.Resources>
    <ResourceDictionary>            
        <!--
        To workout the names of the brushes you need to lookup the relevant control in the following file:
        C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.18362.0\Generic\generic.xaml
        For instance ListBoxItem
        -->            
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Dark">
                <!-- Selected & SelectedUnfocused -->
                <SolidColorBrush x:Key="SystemControlHighlightListAccentLowBrush" Color="#11FFFFFF" />
                <SolidColorBrush x:Key="SystemControlHighlightBaseHighBrush" Color="#11FFFFFF" />
                <!-- SelectedPointerOver -->
                <SolidColorBrush x:Key="SystemControlHighlightListAccentMediumBrush" Color="#11FFFFFF" />
                <SolidColorBrush x:Key="SystemControlHighlightAltBaseHighBrush" Color="#11FFFFFF" />
                <!-- SelectedPressed -->
                <SolidColorBrush x:Key="SystemControlHighlightListAccentHighBrush" Color="#11FFFFFF" />
            </ResourceDictionary>

            <ResourceDictionary x:Key="Light">
                <!-- Selected & SelectedUnfocused -->
                <SolidColorBrush x:Key="SystemControlHighlightListAccentLowBrush" Color="#11000000" />
                <SolidColorBrush x:Key="SystemControlHighlightBaseHighBrush" Color="#11000000" />
                <!-- SelectedPointerOver -->
                <SolidColorBrush x:Key="SystemControlHighlightListAccentMediumBrush" Color="#11000000" />
                <SolidColorBrush x:Key="SystemControlHighlightAltBaseHighBrush" Color="#11000000" />
                <!-- SelectedPressed -->
                <SolidColorBrush x:Key="SystemControlHighlightListAccentHighBrush" Color="#11000000" />
            </ResourceDictionary>
        </ResourceDictionary.ThemeDictionaries>
    </ResourceDictionary>
</Application.Resources>
