合并后的资源字典是否可以访问 App.xaml 中的资源?
Can merged resource dictionaries access resources from App.xaml?
merged resource dictionaries 可以访问 App.xaml
的资源吗?目标是拆分样式以使其更具可读性。
这就是我要找的东西,但不是这样的:
App.xaml 在 UWP 项目中
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles\DefaultButtonStyle.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
<!-- other custom styles, definitions, ThemeDictionaries, ... -->
<Color x:Key="Primary">#dfdfdf</Color>
</Application.Resources>
DefaultButtonStyle.xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:AppName.UWP.Styles">
<!-- some definitions -->
<Style TargetType="Button" x:Key="DefaultButtonStyle">
<!-- my styles -->
<Setter Property="Background" Value="{StaticResource Primary}" />
</Style>
</ResourceDictionary>
应用崩溃
Cannot find a Resource with the Name/Key Primary
我可以将所有内容都放在一个大 style.xaml 中,或者在每个 xaml 文件中复制所需的值,但是没有其他选择吗?合并词典可以包含另一个合并词典吗?或者类似的东西?
试试这个:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles\DefaultButtonStyle.xaml"/>
</ResourceDictionary.MergedDictionaries>
<!-- other custom styles, definitions, ThemeDictionaries, ... -->
<Color x:Key="Primary">#dfdfdf</Color>
</ResourceDictionary>
</Application.Resources>
我使用过分开的词典,并尽量保持它们的使用顺序。在我的应用程序中,我有:
- ColorsAndBrushes.xaml
- SizesAndLayout.xaml
- DefaultStyles.xaml
- NamedStyles.xaml
ColorsAndBrushes 看起来像:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyApp.App.Styles">
<!-- Colors -->
<Color x:Key="Color_Banner">#FF333232</Color>
<!--overridden from themeresource-->
<Color x:Key="SystemChromeDisabledLowColor">#FFA8A49F</Color>
<Color x:Key="SystemAccentColor">#FF2877CF</Color>
<!-- /Colors -->
<!-- Brushes -->
<SolidColorBrush x:Key="Brush_Banner" Color="{StaticResource Color_Banner}" />
<!-- /Brushes -->
</ResourceDictionary>
尺寸和布局:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyApp.App.Styles">
<!-- Padding -->
<Thickness x:Key="Padding_Button">24,4</Thickness>
<Thickness x:Key="Padding_Dialog">10</Thickness>
<Thickness x:Key="Padding_Content">20</Thickness>
<!-- /Padding -->
<!-- Fonts -->
<FontFamily x:Key="Font_DefaultFamily">Segoe UI</FontFamily>
<FontWeight x:Key="Font_DefaultWeight">SemiLight</FontWeight>
<FontWeight x:Key="Font_NormalWeight">Normal</FontWeight>
<FontWeight x:Key="Font_BoldWeight">Semibold</FontWeight>
<x:Double x:Key="ContentControlFontSizeSmall">11</x:Double>
<x:Double x:Key="Font_NormalSize">20</x:Double>
<x:Double x:Key="Font_H1Size">36</x:Double>
<x:Double x:Key="Font_H2Size">28</x:Double>
<!-- /Fonts -->
</ResourceDictionary>
DefaultStyles(适用于所有类型 - 这些使用来自其他 2 个的资源):
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyApp.App.Styles">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ColorsAndBrushes.xaml" />
<ResourceDictionary Source="SizesAndLayout.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style TargetType="TextBlock">
<Setter Property="FontFamily" Value="{StaticResource Font_DefaultFamily}" />
<Setter Property="FontWeight" Value="{StaticResource Font_DefaultWeight}" />
<Setter Property="FontSize" Value="{StaticResource Font_NormalSize}" />
<Setter Property="TextWrapping" Value="WrapWholeWords" />
</Style>
</ResourceDictionary>
和 NamedStyles 是对默认值的覆盖:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyApp.App.Styles">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ColorsAndBrushes.xaml" />
<ResourceDictionary Source="SizesAndLayout.xaml" />
<ResourceDictionary Source="DefaultStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style x:Key="FontStyle_H1" TargetType="TextBlock" BasedOn="{StaticResource FontStyle_Default}">
<Setter Property="FontSize" Value="{StaticResource Font_H1Size}" />
<Setter Property="Foreground" Value="{StaticResource Brush_DarkBlue}" />
<Setter Property="Margin" Value="{StaticResource Margin_TitleFont}" />
</Style>
</ResourceDictionary>
最后,在 App.xaml 中:
<Application
x:Class="MyApp.App.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyApp.App"
RequestedTheme="Light">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/ColorsAndBrushes.xaml" />
<ResourceDictionary Source="Styles/SizesAndLayout.xaml" />
<ResourceDictionary Source="Styles/DefaultStyles.xaml" />
<ResourceDictionary Source="Styles/NamedStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
它对我有用,并通过使用较小范围的文件使 XAML 文件更小。但是,我要说的是,有时 Visual Studio 会给我一大堆抱怨它无法确定命名空间的问题……但只有在文件打开时才会出现。
我也经历过,虽然在运行时,静态资源声明的顺序并不重要,但有时 Visual Studio 中的设计器如果样式不是自上而下的格式,则不会呈现它们。
祝你好运!
