Uwp 如何更改NavigationViewItem中的字体颜色（前景）？

您将看到我正在创建一个UWP应用程序，我正在使用（NavigationView）作为主菜单，在NavigationViewItem中，我已设法更改背景、选择行等，但我无法更改字体颜色

样本截图

我的xaml代码：

 <NavigationView Grid.Row="1" x:Name="nvSample" PaneDisplayMode="Top" SelectionChanged="NvSample_SelectionChanged"
              IsSettingsVisible="True" IsBackButtonVisible="Collapsed">


        <NavigationView.MenuItems>
            <NavigationViewItem Content="Menu Item1" Tag="Home_Page" HorizontalAlignment="Stretch" Height="38" Margin="12,0,0,0" VerticalAlignment="Stretch"  />
            <NavigationViewItem Content="Instalpage" Tag="Install_Page" />
            <NavigationViewItem Content="Menu Item3" Tag="SamplePage3" />
            <NavigationViewItem Content="Menu Item4" Tag="SamplePage4" />


        </NavigationView.MenuItems>

        <Frame x:Name="contentFrame" >

        <Frame.ContentTransitions>
            <TransitionCollection>
                    <NavigationThemeTransition>
                        <DrillInNavigationTransitionInfo />
                    </NavigationThemeTransition>
            </TransitionCollection>
        </Frame.ContentTransitions>
         </Frame>

            <NavigationView.PaneFooter>

                <StackPanel Orientation="Horizontal">
                    <!--<NavigationViewItem Icon="SelectAll" Content="Select all" Foreground="White" />
                    <NavigationViewItem Icon="Help" Content="Help" />-->

                </StackPanel>

            </NavigationView.PaneFooter>

    </NavigationView>

但是我不能改变字体的颜色

您可以使用

TextBlock

控件作为NavigationViewItem的内容，然后可以为TextBlock控件设置

前台

属性

请参阅以下代码示例以供参考：

<NavigationView Grid.Row="1" x:Name="nvSample" PaneDisplayMode="Top"
          IsSettingsVisible="True" IsBackButtonVisible="Collapsed">
        <NavigationView.MenuItems>
            <NavigationViewItem Tag="Home_Page" HorizontalAlignment="Stretch" Height="38" Margin="12,0,0,0" VerticalAlignment="Stretch">
                <NavigationViewItem.Content>
                    <TextBlock Text="Menu Item1" Foreground="Red"></TextBlock>
                </NavigationViewItem.Content>
            </NavigationViewItem>
            <NavigationViewItem Content="Instalpage" Tag="Install_Page" />
            <NavigationViewItem Content="Menu Item3" Tag="SamplePage3" />
            <NavigationViewItem Content="Menu Item4" Tag="SamplePage4" />
        </NavigationView.MenuItems>
        <Frame x:Name="contentFrame" >

            <Frame.ContentTransitions>
                <TransitionCollection>
                    <NavigationThemeTransition>
                        <DrillInNavigationTransitionInfo />
                    </NavigationThemeTransition>
                </TransitionCollection>
            </Frame.ContentTransitions>
        </Frame>
        <NavigationView.PaneFooter>
            <StackPanel Orientation="Horizontal">
                <!--<NavigationViewItem Icon="SelectAll" Content="Select all" Foreground="White" />
                <NavigationViewItem Icon="Help" Content="Help" />-->
            </StackPanel>

    </NavigationView>

NavigationViewItem确实有一个名为前台的属性，它对我很有用

<NavigationView.MenuItems>
        <NavigationViewItem Content="Menu Item1" Foreground="Black" Tag="Home_Page" Height="38" HorizontalAlignment="Stretch" Margin="0,0,0,0" VerticalAlignment="Stretch"  />
        <NavigationViewItem Content="Instalpage" Foreground="Black" Tag="Install_Page" />
        <NavigationViewItem Content="Menu Item3" Foreground="Black" Tag="SamplePage3" />
        <NavigationViewItem Content="Menu Item4" Foreground="Black" Tag="SamplePage4" />
</NavigationView.MenuItems>
