推荐答案
这不会很漂亮.由于"UpperHighlight" Rectangle 是默认 ListViewItem 模板的一部分，因此可以提供额外的颜色，并且无法从外部进行访问.因此，您只需覆盖整个模板.
This ain't gonna be pretty. That extra color is there thanks to an "UpperHighlight" Rectangle that is part of the default ListViewItem Template, and it is not accessible from outside. So you're only left with overwriting the whole Template.
首先，将其添加到您的资源中:
First of all, add this to your Resources:
<Style x:Key="ListViewItemFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle RadiusY="2" RadiusX="2" Stroke="#8E6EA6F5" StrokeThickness="1"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<LinearGradientBrush x:Key="ListItemHoverFill" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#FFF1FBFF" Offset="0"/>
<GradientStop Color="#FFD5F1FE" Offset="1"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="ListItemSelectedFill" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#FFD9F4FF" Offset="0"/>
<GradientStop Color="#FF9BDDFB" Offset="1"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="ListItemSelectedInactiveFill" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#FFEEEDED" Offset="0"/>
<GradientStop Color="#FFDDDDDD" Offset="1"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="ListItemSelectedHoverFill" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#FFEAF9FF" Offset="0"/>
<GradientStop Color="#FFC9EDFD" Offset="1"/>
</LinearGradientBrush>
然后将其添加到您的 ListViewItem 样式:
And then add this to your ListViewItem Style:
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<!-- ... Your other Setters -->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="2" SnapsToDevicePixels="true">
<Border x:Name="InnerBorder" BorderThickness="1" CornerRadius="1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition MaxHeight="11"/>
<RowDefinition/>
</Grid.RowDefinitions>
<!--<Rectangle x:Name="UpperHighlight" Fill="#75FFFFFF" Visibility="Collapsed"/>-->
<GridViewRowPresenter Grid.RowSpan="2" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</Border>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="{StaticResource ListItemHoverFill}"/>
<Setter Property="BorderBrush" Value="#FFCCF0FF"/>
<!--<Setter Property="Visibility" TargetName="UpperHighlight" Value="Visible"/>-->
</Trigger>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" Value="{StaticResource ListItemSelectedFill}"/>
<Setter Property="BorderBrush" Value="#FF98DDFB"/>
<Setter Property="BorderBrush" TargetName="InnerBorder" Value="#80FFFFFF"/>
<!--<Setter Property="Visibility" TargetName="UpperHighlight" Value="Visible"/>
<Setter Property="Fill" TargetName="UpperHighlight" Value="#40FFFFFF"/>-->
</Trigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="true"/>
<Condition Property="Selector.IsSelectionActive" Value="false"/>
</MultiTrigger.Conditions>
<Setter Property="Background" Value="{StaticResource ListItemSelectedInactiveFill}"/>
<Setter Property="BorderBrush" Value="#FFCFCFCF"/>
</MultiTrigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="true"/>
<Condition Property="IsMouseOver" Value="true"/>
</MultiTrigger.Conditions>
<Setter Property="Background" Value="{StaticResource ListItemSelectedHoverFill}"/>
<Setter Property="BorderBrush" Value="#FF98DDFB"/>
</MultiTrigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<!-- ... Your Triggers -->
</Style.Triggers>
</Style>
</ListView.ItemContainerStyle>
