xaml – 如何设置PivotItem标头样式

我有一个我正在使用的现有Pivot标题模板,但它没有给我我需要的效果.我需要当前选择的PivotItem具有蓝色前景和白色背景,而所有其他枢轴项目具有标准禁用前景和背景外观.目前下面我有我认为除了选定的PivotItem上的蓝色前景之外的一切,但我无法弄清楚如何正确地将前景应用于所选项目？

<Style x:Key="PivotHeaderItemStyle1" targettype="Primitives:PivotHeaderItem">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="Padding" Value="21,1,0"/>
        <Setter Property="Margin" Value="0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate targettype="Primitives:PivotHeaderItem">
                    <Grid>                          
                        <visualstatemanager.VisualStateGroups>
                            <VisualStateGroup x:Name="SelectionStates">
                                <VisualState x:Name="Unselected">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="{StaticResource PhonedisabledColor}"/>
                                    </Storyboard>
                                </VisualState>
                                <VisualState x:Name="Selected">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="{StaticResource PhoneBackgroundColor}"/>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </visualstatemanager.VisualStateGroups>                            
                        <Border x:Name="myback" Background="{TemplateBinding Background}">
                            <ContentControl x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"/>
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <Style x:Key="PivotStyle1" targettype="phone:Pivot">
        <Setter Property="Margin" Value="0"/>
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="ItemsPanel">
            <Setter.Value>
                <ItemsPanelTemplate>
                    <Grid/>
                </ItemsPanelTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate targettype="phone:Pivot">
                    <Grid HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
                        <Grid.RowDeFinitions>
                            <RowDeFinition Height="Auto"/>
                            <RowDeFinition Height="Auto"/>
                            <RowDeFinition Height="*"/>
                        </Grid.RowDeFinitions>
                        <Grid Background="{TemplateBinding Background}" Grid.RowSpan="3"/>
                        <ContentControl x:Name="TitleElement" ContentTemplate="{TemplateBinding TitleTemplate}" Content="{TemplateBinding Title}" HorizontalAlignment="Left" Margin="24,-7" Style="{StaticResource PivottitleStyle}"/>
                        <Primitives:PivotHeadersControl x:Name="HeadersListElement" Grid.Row="1" ItemContainerStyle="{StaticResource PivotHeaderItemStyle1}" FontSize="70"/>
                        <ItemsPresenter x:Name="PivotItemPresenter" Margin="{TemplateBinding Padding}" Grid.Row="2"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

更改< ContentPresenter>到< TextBlock>

像这样

<Style x:Key="PivotHeaderItemStyle1" targettype="Primitives:PivotHeaderItem">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="Padding" Value="10,10,0"/>
    <Setter Property="Margin" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate targettype="Primitives:PivotHeaderItem">
                <Grid>
                    <visualstatemanager.VisualStateGroups>
                        <VisualStateGroup x:Name="SelectionStates">
                            <VisualState x:Name="Unselected">
                                <Storyboard>
                                    <ColorAnimation Duration="0" Storyboard.TargetName="border_highlight" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="Transparent"/>
                                    <ColorAnimation  Duration="0" Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" To="Green"/>
                                </Storyboard>
                            </VisualState>
                            <VisualState x:Name="Selected">
                                <Storyboard>
                                    <ColorAnimation  Duration="0:0:1" Storyboard.TargetName="border_highlight" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="PaleGreen"/>
                                    <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="contentPresenter"/>
                                    <ColorAnimation  Duration="0" Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" To="Blue"/>
                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                    </visualstatemanager.VisualStateGroups>
                    <Border x:Name="border_highlight" Background="{TemplateBinding Background}" >
                        <!--<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"/>-->
                        <TextBlock x:Name="contentPresenter" Foreground="{TemplateBinding Foreground}" Text="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"></TextBlock>
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后你可以动画前景.这是上面代码的屏幕截图.选择颜色=蓝色,未选择颜色=绿色.您需要在背景动画中添加回来.
