我的底线是xaml
<Page.BottomAppBar>
<CommandBar>
<AppBarButton Style="{StaticResource AppBarButtonStyle1}" Icon="Bookmarks"></AppBarButton>
<AppBarButton Style="{StaticResource AppBarButtonStyle1}" >
<AppBarButton.Icon>
<SymbolIcon Symbol="Accept"></SymbolIcon>
</AppBarButton.Icon>
</AppBarButton>
</CommandBar>
</Page.BottomAppBar>
您不能单独这样做。应用程序栏是系统UI,不支持自定义图标颜色 您可以通过设置CommandBar.Foreground和.Background属性来设置整个应用程序栏的主题。图标将全部以前景色绘制,命令栏本身以背景色绘制:
<Page.BottomAppBar>
<CommandBar Foreground="Cyan" Background="Magenta">
<AppBarButton Icon="Bookmarks"></AppBarButton>
<AppBarButton >
<AppBarButton.Icon>
<SymbolIcon Symbol="Accept"></SymbolIcon>
</AppBarButton.Icon>
</AppBarButton>
</CommandBar>
</Page.BottomAppBar>
如果你真的想单独定制按钮,那么你不能把它们放在应用程序栏中。相反,您可以在页面底部停靠一个小stackpanel并编辑AppBarButton的样式以更改椭圆的颜色(将其笔划设置为{TemplateBinding Foreground}将使其与AppBarButton中设置的前景匹配)
除了演示之外,我不推荐使用这些颜色组合:在真实的应用程序中,颜色应该从主题词典中提取,该词典在高对比度主题中返回默认值。设置CommandBar前景颜色对AppBarButton没有任何影响,您必须单独设置AppBarButton颜色。自从您发布此答案后,情况一定发生了变化。此外,您现在可以在命令栏中单独设置颜色。
