问题描述
我在 WinRT Windows Phone 8.1 应用程序中有一个 Page.此页面将 RequestedTheme 设置为 ElementTheme.Light.系统主题(在系统设置中设置)设置为深色.
I have a Page in a WinRT Windows Phone 8.1 application. This Page has RequestedTheme set to ElementTheme.Light. The system theme (as set in system settings) is set to dark.
当我打开一个 ListPickerFlyout(使用 Button.Flyout)时，结果如下:
When I open a ListPickerFlyout (using Button.Flyout), the result is the following:
看起来，前景色适当地更改为黑色，但背景保持深色主题(非常深的灰色).
It seems, that the foreground color appropriately changes to black, but the background stays dark-themed (a very dark gray).
浮出控件上没有 Background 属性，有没有办法强制它符合页面的 RequestedTheme?
There isn't a Background property on the flyout, is there a way to force it to comply with the Page's RequestedTheme?
推荐答案
好问题！
在应用程序资源中，您可以为 Light 主题覆盖一个名为 FlyoutBackgroundThemeBrush 的资源.
In the application resources, you can override a resource called FlyoutBackgroundThemeBrush for Light themes.
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Light">
<SolidColorBrush x:Key="FlyoutBackgroundThemeBrush" Color="Green" />
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
</ResourceDictionary>
</Application.Resources>
这将使概念验证变得绿色.:)
This will make it green for proof of concept. :)
