WPF C#如何设置HighlightBrush颜色的动画？

我正在尝试为ListView的选定项颜色设置动画

我可以通过以下代码访问此“属性”：

<Style.Resources>
      <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Blue">
</Style.Resources>

如何设置此“属性”颜色的动画

非常感谢

这是样本样式；-）

它使用ListViewItem的模板，您可以在其中为IsSelected属性的触发器输入/退出操作中添加带有彩色动画的Stoyboard

<Style TargetType="{x:Type ListViewItem}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Border x:Name="Bd" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
                    <Grid>
                        <GridViewRowPresenter VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
                        <ContentPresenter x:Name="contentPresenter" Visibility="Collapsed" />
                    </Grid>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="GridView.ColumnCollection" Value="{x:Null}">
                        <Setter TargetName="contentPresenter" Property="Visibility" Value="Visible"/>
                    </Trigger>
                    <Trigger Property="IsSelected" Value="true">
                        <Trigger.EnterActions>
                            <BeginStoryboard>
                                <Storyboard>
                                    <ColorAnimation Storyboard.TargetName="Bd" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"
                                                    From="Red" To="Blue" Duration="0:0:1" />
                                </Storyboard>
                            </BeginStoryboard>
                        </Trigger.EnterActions>
                        <Trigger.ExitActions>
                            <BeginStoryboard>
                                <Storyboard>
                                    <ColorAnimation Storyboard.TargetName="Bd" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"
                                                    From="Blue" To="Transparent" Duration="0:0:1" />
                                </Storyboard>
                            </BeginStoryboard>
                        </Trigger.ExitActions>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

我认为你不能。。。静态资源在应用程序加载后设置，即使您确实更改了它，我也不认为绑定到它的对象会得到重新评估，因为它们可能使用

{StaticResource…}

并期望值是静态的。是的，rachel是对的，但是，您可以为ListViewItem创建一个样式，如果该项目被选中，您可以在那里添加一个彩色动画…我将在有时间时尽快用示例代码回答您的问题；）@谢谢你，我会耐心等待的。谢谢
