我正在尝试向 menuflyoutitem 添加一个图标，我希望我的菜单看起来类似于这个：

在此处输入图像描述

这是我的代码：

<AppBarButton.Flyout>
    <MenuFlyout>
        <MenuFlyoutItem Text="SMS">
            <MenuFlyoutItem.Template>
                <ControlTemplate TargetType="MenuFlyoutItem">
                    <StackPanel Margin="12,10,0,0" Orientation="Horizontal">
                        <SymbolIcon Margin="0,0,12,0" Symbol="Comment" />
                        <TextBlock Text="{TemplateBinding Text}" />
                    </StackPanel>
                </ControlTemplate>
            </MenuFlyoutItem.Template>
        </MenuFlyoutItem>
        <MenuFlyoutItem Text="Email">
            <MenuFlyoutItem.Template>
                <ControlTemplate TargetType="MenuFlyoutItem">
                    <StackPanel Margin="12,10,0,10" Orientation="Horizontal">
                        <SymbolIcon Margin="0,0,12,0" Symbol="MailForward" />
                        <TextBlock Text="{TemplateBinding Text}" />
                    </StackPanel>
                </ControlTemplate>
            </MenuFlyoutItem.Template>
        </MenuFlyoutItem>
    </MenuFlyout>
</AppBarButton.Flyout>

我一直在苦苦挣扎，找不到关于它的正常教程，有人知道我应该改变吗？因为当我添加图标时，菜单的所有行为都会丢失，例如，当我在菜单上时它不会再次改变颜色。谢谢。

幸亏Windows 10 Creators Update (introduced v10.0.15063.0) MenuFlyoutItem现在有了财产Icon。

来自微软文档：

<MenuFlyout>
    <MenuFlyoutItem Text="Share" >
        <MenuFlyoutItem.Icon>
            <FontIcon Glyph="&#xE72D;" />
        </MenuFlyoutItem.Icon>
    </MenuFlyoutItem>
</MenuFlyout>

有关更多信息，请务必查看：MenuFlyoutItem 文档

菜单的所有行为都丢失了，因为您使用的是自定义MenuFlyoutItem模板，并且在您的模板中，您没有处理不同的视觉状态。

默认情况下，MenuFlyoutItem有 8 个视觉状态，分别是Normal、PointerOver、Pressed、Disabled、Unchecked、Checked、DefaultPadding和NarrowPadding。有关更多信息，请查看MenuFlyoutItem 样式和模板。

当您在菜单上时，它会触发PointerOver状态：

<VisualState x:Name="PointerOver">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="LayoutRoot" Storyboard.TargetProperty="Background">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightListLowBrush}" />
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="TextBlock" Storyboard.TargetProperty="Foreground">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightAltBaseHighBrush}" />
        </ObjectAnimationUsingKeyFrames>
        <PointerUpThemeAnimation Storyboard.TargetName="TextBlock" />
    </Storyboard>
</VisualState>

在这种状态下，它会改变背景和 TextBlock 的前景。但是在您的自定义模板中，您没有任何VisualState，所以它没有改变颜色。

要解决此问题，您可以为每个自定义模板添加视觉状态。

或者您可以根据默认样式和模板创建自定义样式，并使用Tag属性进行设置SymbolIcon：

<Style x:Key="MyMenuFlyoutItem" TargetType="MenuFlyoutItem">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}" />
    <Setter Property="Padding" Value="{ThemeResource MenuFlyoutItemThemePadding}" />
    <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
    <Setter Property="HorizontalContentAlignment" Value="Stretch" />
    <Setter Property="VerticalContentAlignment" Value="Center" />
    <Setter Property="UseSystemFocusVisuals" Value="True" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="MenuFlyoutItem">

                        <TextBlock x:Name="TextBlock"
                                   HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                   VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                   Foreground="{TemplateBinding Foreground}"
                                   Text="{TemplateBinding Text}"
                                   TextTrimming="Clip" />
                    </StackPanel>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后，在你的MenuFlyoutItem：

<AppBarButton.Flyout>
    <MenuFlyout>
        <MenuFlyoutItem Style="{StaticResource MyMenuFlyoutItem}" Tag="Comment" Text="SMS" />
        <MenuFlyoutItem Style="{StaticResource MyMenuFlyoutItem}" Tag="MailForward" Text="Email" />
    </MenuFlyout>
</AppBarButton.Flyout>

我使用的样式只是举例，您可能需要对其进行编辑以满足您的需要。

MenuFlyoutIconGlyphIcon

 public class MenuFlyoutIconGlyph : MenuFlyoutItem
{
    public string GlyphIcon
    {
        get { return (string)GetValue(GlyphIconProperty); }
        set { SetValue(GlyphIconProperty, value); }
    }
    public static readonly DependencyProperty GlyphIconProperty =
        DependencyProperty.Register("GlyphIcon", typeof(string), typeof(MenuFlyoutIconGlyph), new PropertyMetadata("uE10C"));
