我的目标是模仿类似的效果：

有资源在线描述如何做,但所有这些都适用于Windows Phone 8. 8.1更新带来严重的API更改,使代码无用.

那么,怎样才能调整头文件头？我发现命名空间Windows.UI.Xaml.Controls.Primitives,其中包括类PivotHeaderPanel,这可能在这种情况下有帮助,但我找不到从XAML访问此类的方法.
还是还有另一种方式？
解决方法
如果您只想更改所有标题的背景颜色,那么您可以在Window Phone 8.1中进行操作.
首先,使用Expression Blend生成Pivot控件的默认样式.
<Thickness x:Key="PivotPortraitThemePadding">19,38,0</Thickness>
<Thickness x:Key="PivotLandscapeThemePadding">19,25,0</Thickness>
<Style x:Key="CustomPivotStyle" TargetType="Pivot">
<Setter Property="Margin" Value="0"/>
<Setter Property="Padding" Value="0"/>
<Setter Property="Foreground" Value="{ThemeResource PhoneForegroundBrush}"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<Grid/>
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Pivot">
<Grid x:Name="RootElement" Background="{TemplateBinding Background}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="Orientation">
<VisualState x:Name="Portrait">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Margin" Storyboard.TargetName="TitleContentControl">
<DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource PivotPortraitThemePadding}"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Landscape">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Margin" Storyboard.TargetName="TitleContentControl">
<DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource PivotLandscapeThemePadding}"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentControl x:Name="TitleContentControl" ContentTemplate="{TemplateBinding TitleTemplate}" Content="{TemplateBinding Title}" Style="{StaticResource PivotTitleContentControlStyle}"/>
<ScrollViewer x:Name="ScrollViewer" HorizontalSnapPointsAlignment="Center" HorizontalSnapPointsType="MandatorySingle" HorizontalScrollBarVisibility="Hidden" Margin="{TemplateBinding Padding}" Grid.Row="1" Template="{StaticResource ScrollViewerScrollBarlessTemplate}" VerticalSnapPointsType="None" VerticalScrollBarVisibility="Disabled" VerticalScrollMode="Disabled" VerticalContentAlignment="Stretch" ZoomMode="Disabled">
<PivotPanel x:Name="Panel" VerticalAlignment="Stretch">
<PivotHeaderPanel x:Name="Header" Background="{TemplateBinding BorderBrush}">
<PivotHeaderPanel.RenderTransform>
<CompositeTransform x:Name="HeaderTranslateTransform" TranslateX="0"/>
</PivotHeaderPanel.RenderTransform>
</PivotHeaderPanel>
<ItemsPresenter x:Name="PivotItemPresenter">
<ItemsPresenter.RenderTransform>
<TranslateTransform x:Name="ItemsPresenterTranslateTransform" X="0"/>
</ItemsPresenter.RenderTransform>
</ItemsPresenter>
</PivotPanel>
</ScrollViewer>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
在下面找到这一行,我对默认样式的唯一变化是将Background =“{TemplateBinding BorderBrush}”添加到托管所有标题的面板的PivotHeaderPanel中.
<PivotHeaderPanel x:Name="Header" Background="{TemplateBinding BorderBrush}">
我在这里使用TemplateBinding的原因是因为这样做可以通过指定数据透视的BorderBush来灵活地更改标题背景.由于BorderBrush在控件中的任何位置都不被使用,所以如果我们改变它就不会有任何副作用.
所以你所需要做的就是这个.
<Pivot x:Uid="Pivot" Title="MY APPLICATION" x:Name="pivot" CommonNavigationTransitionInfo.IsStaggerElement="True" Style="{StaticResource CustomPivotStyle}" BorderBrush="{StaticResource PhoneAccentBrush}">
这就是他们现在的样子.
希望这可以帮助！
