win10 uwp 修改Pivot Header 颜色	lindexi	2018-08-10 19:17:19 +0800	2018-2-13 17:23:3 +0800	Win10 UWP

我们在xaml创建一个Pivot

        <Pivot Grid.Row="1">
            <PivotItem Header="lindexi"></PivotItem>
            <PivotItem Header="CSDN"></PivotItem>

        </Pivot>

这样的Header是默认颜色

我们想修改颜色，可以使用

    <Pivot.HeaderTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding}" Foreground="Cyan" FontSize="40" />
        </DataTemplate>
    </Pivot.HeaderTemplate>

参见： http://stackoverflow.com/questions/31797875/overriding-pivot-header-foreground-brushes-in-uwp-app-win-10-rtm-sdk

但是如果我们要修改多的Pivot，使用模板其实还不能修改不选中的Pivot Header的颜色

我写了一个Style，可以直接复制到需要使用Pivot的Grid资源

        <Style TargetType="PivotHeaderItem">
            <Setter Property="FontSize" Value="{ThemeResource PivotHeaderItemFontSize}" />
            <Setter Property="FontFamily" Value="{ThemeResource PivotHeaderItemFontFamily}" />
            <Setter Property="FontWeight" Value="{ThemeResource PivotHeaderItemThemeFontWeight}" />
            <Setter Property="CharacterSpacing" Value="{ThemeResource PivotHeaderItemCharacterSpacing}" />
            <Setter Property="Background" Value="Transparent" />
            <Setter Property="Foreground" Value="{StaticResource PivotHeaderForegroundUnselectedBrush}" />
            <!-- original value {ThemeResource SystemControlForegroundBaseMediumBrush} -->
            <Setter Property="Padding" Value="{ThemeResource PivotHeaderItemMargin}" />
            <Setter Property="Height" Value="48" />
            <Setter Property="VerticalContentAlignment" Value="Center" />
            <Setter Property="IsTabStop" Value="False" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="PivotHeaderItem">
                        <Grid x:Name="Grid" Background="{TemplateBinding Background}">
                            <Grid.Resources>
                                <Style x:Key="BaseContentPresenterStyle" TargetType="ContentPresenter">

                                    <Setter Property="FontWeight" Value="SemiBold" />
                                    <Setter Property="FontSize" Value="15" />

                            </Grid.Resources>
                            <VisualStateManager.VisualStateGroups>

                                              HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                                              VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
                                <ContentPresenter.RenderTransform>
                                    <TranslateTransform x:Name="ContentPresenterTranslateTransform" />
                                </ContentPresenter.RenderTransform>
                            </ContentPresenter>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

接着在style的前面写

       <SolidColorBrush x:Key="PivotHeaderSelectedForegroundBrush" Color="BurlyWood"></SolidColorBrush>
        <SolidColorBrush x:Key="PivotHeaderUnselectedPressedForegroundBrush" Color="Brown"></SolidColorBrush>
        <SolidColorBrush x:Key="PivotHeaderForegroundUnselectedBrush" Color="Cyan" />
        <SolidColorBrush x:Key="PivotHeaderUnselectedPointerOverForegroundBrush" Color="BurlyWood"></SolidColorBrush>
        <SolidColorBrush x:Key="PivotHeaderSelectedPointerOverForegroundBrush" Color="BurlyWood"></SolidColorBrush>

PivotHeaderSelectedForegroundBrush 就是PivotHeader 被选择的颜色

PivotHeaderUnselectedPressedForegroundBrush 是PivotHeader 不被选择的颜色

PivotHeaderUnselectedPointerOverForegroundBrush 是鼠标移到 没被选择的PivotHeader 上的颜色

PivotHeaderSelectedPointerOverForegroundBrush 是鼠标移到 被选择的PivotHeader 上的颜色

如果希望修改其他颜色，请自己去看style可以修改的颜色，如果遇到问题，欢迎讨论。
