图 1 是设备处于深色模式时的情况。
图 2 是设备处于灯光模式时的情况。
我仍然可以单击它并访问我定义的工具栏项目,但图标不可见。
知道为什么会发生这种情况吗?
是风格问题吗?这是我得到的样式,我使用的是 shell
<Style TargetType="Shell" ApplyToDerivedTypes="True">
<Setter Property="Shell.BackgroundColor" Value="{AppThemeBinding Light={StaticResource Primary}, Dark={StaticResource Gray950}}" />
<Setter Property="Shell.ForegroundColor" Value="{OnPlatform WinUI={StaticResource Primary}, Default={StaticResource White}}" />
<Setter Property="Shell.TitleColor" Value="{AppThemeBinding Light={StaticResource White}, Dark={StaticResource White}}" />
<Setter Property="Shell.DisabledColor" Value="{AppThemeBinding Light={StaticResource Gray200}, Dark={StaticResource Gray950}}" />
<Setter Property="Shell.UnselectedColor" Value="{AppThemeBinding Light={StaticResource Gray200}, Dark={StaticResource Gray200}}" />
<Setter Property="Shell.NavBarHasShadow" Value="False" />
<Setter Property="Shell.TabBarBackgroundColor" Value="{AppThemeBinding Light={StaticResource White}, Dark={StaticResource Black}}" />
<Setter Property="Shell.TabBarForegroundColor" Value="{AppThemeBinding Light={StaticResource Primary}, Dark={StaticResource White}}" />
<Setter Property="Shell.TabBarTitleColor" Value="{AppThemeBinding Light={StaticResource Primary}, Dark={StaticResource White}}" />
<Setter Property="Shell.TabBarUnselectedColor" Value="{AppThemeBinding Light={StaticResource Gray900}, Dark={StaticResource Gray200}}" />
</Style>
<Style TargetType="NavigationPage">
<Setter Property="BarBackgroundColor" Value="{AppThemeBinding Light={StaticResource Primary}, Dark={StaticResource Gray950}}" />
<Setter Property="BarTextColor" Value="{AppThemeBinding Light={StaticResource Gray200}, Dark={StaticResource White}}" />
<Setter Property="IconColor" Value="{AppThemeBinding Light={StaticResource Gray200}, Dark={StaticResource White}}" />
</Style>
<Style TargetType="TabbedPage">
<Setter Property="BarBackgroundColor" Value="{AppThemeBinding Light={StaticResource White}, Dark={StaticResource Gray950}}" />
<Setter Property="BarTextColor" Value="{AppThemeBinding Light={StaticResource Primary}, Dark={StaticResource White}}" />
<Setter Property="UnselectedTabColor" Value="{AppThemeBinding Light={StaticResource Gray200}, Dark={StaticResource Gray950}}" />
<Setter Property="SelectedTabColor" Value="{AppThemeBinding Light={StaticResource Gray950}, Dark={StaticResource Gray200}}" />
</Style>
在您的.xaml中(以MainPage.xaml为例),添加以下内容:
...
<ContentPage.ToolbarItems>
<ToolbarItem Text="Example Item"
Order="Secondary"
Priority="0" />
</ContentPage.ToolbarItems>
...
更多信息,您可以参考Xamarin.Forms ToolbarItem。
我也有同样的问题,我的 3 个点总是白色的...如何改变它?
