Question

我在CommandBar SecondaryCommands中有一个菜单，我列出了样式CommandBar，但我没有找到让我在菜单中的每个项目上悬停时更改前景颜色的行。这是我的代码：

这是我的CommandBar代码：

<CommandBar Style="{Binding Source={StaticResource commandBarStyle}}" >
            <CommandBar.CommandBarOverflowPresenterStyle>
                <Style TargetType="CommandBarOverflowPresenter">
                    <Setter Property="Background"
                        Value="#00a0e3" ></Setter>
                    <Setter Property="Margin" Value="0"></Setter>
                    <Setter Property="Padding" Value="0"></Setter>
                    <Setter Property="BorderBrush" Value="Transparent"/>
                 </Style>
            </CommandBar.CommandBarOverflowPresenterStyle>

            <CommandBar.SecondaryCommands >
                <AppBarButton Label="Info"
                          Foreground="White" Background="#00a0e3"/>
            </CommandBar.SecondaryCommands>
        </CommandBar>
    </Page.BottomAppBar>

commandBarStyle是Windows应用商店的CommandBar的默认样式，我在＆＃34; AvailableCommandsStates＆＃34;中添加了这些行。部分：

 <VisualStateGroup x:Name="AvailableCommandsStates">
                                <VisualState x:Name="BothCommands"/>
                                <VisualState x:Name="PrimaryCommandsOnly">
                                    <Storyboard>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="OverflowContentRoot" Storyboard.TargetProperty="Visibility">
                                            <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="Collapsed"/>
                                        </ObjectAnimationUsingKeyFrames>
                                    </Storyboard>
                                </VisualState>

但是当我将鼠标悬停在SecondaryCommands项目上时，总是会得到黑色前景色再次感谢您的帮助

Answer 1

您应该覆盖按钮的样式，而不是栏。您可以在按钮样式中找到PointerOver状态

在通用应用程序中将鼠标悬停在CommandBar SecondaryCommands上时更改前景色
