更改Windows Phone 7主题识别应用程序的颜色

问题描述

我想根据用户在手机上选择的主题来更改矩形的颜色.

I'm wanting to change the color of a rectangle depending on what theme the user has chosen on their phone.

EG.当用户将其设备的主题颜色设置为浅色时，矩形应为蓝色，而当主题设置为深色时，则应为灰色.

EG.When the user has their device's theme color set to light a rectangle should be blue and when the theme is set to dark it should be a grey.

有什么想法吗?

谢谢

推荐答案

我编写了一个自定义资源字典实现，该实现在运行时选择另一个字典而不会影响性能，并且可以在Visual Studio设计器中工作.您将像这样使用它:

I wrote a custom resource dictionary implementation which selects another dictionary at runtime without a performance penalty and works in the Visual Studio designer. You would use it like this:

<Application.Resources>
  <custom:ThemeResourceDictionary>
    <custom:ThemeResourceDictionary.LightResources>
      <ResourceDictionary Source="/ThemeManagement;component/Resources/Light.xaml" />
    </custom:ThemeResourceDictionary.LightResources>
    <custom:ThemeResourceDictionary.DarkResources>
      <ResourceDictionary Source="/ThemeManagement;component/Resources/Dark.xaml" />
    </custom:ThemeResourceDictionary.DarkResources>
  </custom:ThemeResourceDictionary>
</Application.Resources>

其中Light.xaml和Dark.xaml将包含具有相同名称的资源.

Where Light.xaml and Dark.xaml would contain resources with the same names.

您可以获取代码并详细了解在我的博客上.
