我已经查看了将 PivotItemHeader 样式应用于 UWP 中的 PivotItem，但我无法将这些建议应用于我的代码。

我正在尝试根据设备是桌面设备还是移动设备来更改 Pivot 中 PivotHeaderItem(s) 的样式。我的资源字典中有 2 个显式样式。

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Test">

    <Style x:Key="PivotHeaderItemStyle1" TargetType="PivotHeaderItem">
    <Style x:Key="PivotHeaderItemStyle2" TargetType="PivotHeaderItem">

</ResourceDictionary>

我的 MainPage.xaml 是：

    <Page
        x:Class="Test.MainPage"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="using:Test"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d">

        <Page.Resources>
            <ResourceDictionary Source="Dictionary1.xaml"/>
        </Page.Resources>

        <Grid>
            <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="DeviceStates">
                    <VisualState x:Name="Desktop">
                        <VisualState.StateTriggers>
                            <local:DeviceStateTrigger DeviceFamily="Windows.Desktop"/>
                        </VisualState.StateTriggers>
                        <VisualState.Setters>
 I don't know what to put here --->     <Setter Target="PivotHeaderItem1.Style" Value="{StaticResource PivotHeaderItemStyle1}"/>
                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="Mobile">
                        <VisualState.StateTriggers>
                            <local:DeviceStateTrigger DeviceFamily="Windows.Mobile"/>
                        </VisualState.StateTriggers>
                        <VisualState.Setters>
 I don't know what to put here …
