Windows 8 控件更改颜色

抱歉，也许是个愚蠢的问题：我写了一个Windows8应用程序，如果我将鼠标悬停在按钮或ListView上，它们会将颜色更改为白色。如何更改此选项？

您可以更改按钮或列表视图的样式。在自定义样式中，可以为任何VisualState重新定义颜色。关于您的问题，您需要更改PointerOver VisualState的颜色。
您可以看到下面的示例：

<VisualState x:Name="PointerOver">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="Border">
            <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent"/>
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentPresenter">
            <DiscreteObjectKeyFrame KeyTime="0" Value="#0055A5"/>
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</VisualState>

您还可以在下面看到按钮的完整样式：

<Style x:Key="ButtonStyle" TargetType="Button">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="Foreground" Value="#0055A5"/>
    <Setter Property="BorderBrush" Value="#0055A5"/>
    <Setter Property="BorderThickness" Value="{StaticResource ButtonBorderThemeThickness}"/>
    <Setter Property="Padding" Value="12,4,12,4"/>
    <Setter Property="HorizontalAlignment" Value="Left"/>
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="FontFamily" Value="{StaticResource ContentControlThemeFontFamily}"/>
    <Setter Property="FontWeight" Value="SemiBold"/>
    <Setter Property="FontSize" Value="{StaticResource ControlContentThemeFontSize}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Normal"/>
                            <VisualState x:Name="PointerOver">
                                <Storyboard>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="Border">
