本文主要说如何在UWP切换主题,并且如何制作主题。

一般我们的应用都要有多种颜色,一种是正常的白天颜色,一种是晚上的黑夜颜色,还需要一种辅助的高对比颜色。这是微软建议的,一般应用都要包含的颜色。

我们还可以自己定义多种颜色,例如金属、海蓝之光、彩虹雨。然而微软给我们的切换,简单只有亮和暗。

那么问题就是我们如何切换我们的主题。

在这前,我们先说如何制作主题,其实主题就是Dictionary,我们在解决方案加上两个文件夹,一个是View,一个是ViewModel,其中View将会放主题,如果主题比较多,还可以在View加一个文件夹。

技术分享

首先在View文件夹新建资源

技术分享

我根据原文说的新建几个资源叫LightThemeDictionary、DarkThemeDictionary,一个是白天颜色,一个是黑暗

然后我们在我们的资源写入几个资源

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:NightDayThemeToggleButton.View">
    <SolidColorBrush x:Key="SystemBackgroundAltHighBrush" Color="#FFF0F0F0"/>
    <SolidColorBrush x:Key="SystemBackgroundBaseHighBrush" Color="#FF101010"/>
    <Color x:Key="SystemTranslucentBaseHighColor">#FF000000</Color>
    <Color x:Key="SystemThemeMainColor">#FF0074CE</Color>
</ResourceDictionary>

然后在黑暗也写相同key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:NightDayThemeToggleButton.View">

    <SolidColorBrush x:Key="SystemBackgroundAltHighBrush" Color="#FF1A1C37"/>
    <SolidColorBrush x:Key="SystemBackgroundBaseHighBrush" Color="#FFDFDFDF"/>
    <Color x:Key="SystemTranslucentBaseHighColor">#FFFFFFFF</Color>
    <Color x:Key="SystemThemeMainColor">#FF0074CE</Color>
</ResourceDictionary>

然后我们需要在前台把资源放在Page

    <Page.Resources>
        <ResourceDictionary>
            <ResourceDictionary.ThemeDictionaries>
                <ResourceDictionary x:Key="Light" Source="View/DarkThemeDictionary.xaml"></ResourceDictionary>
                <ResourceDictionary x:Key="Dark" Source="View/LightThemeDictionary.xaml"></ResourceDictionary>
            </ResourceDictionary.ThemeDictionaries>
        </ResourceDictionary>
    </Page.Resources>

我们使用资源需要ThemeDictionaries,这个是主题

记住要把资源一个叫x:Key="Light"一个Dark,原因在下面会说。

我们建立ViewModel,其中ViewModel继承NotifyProperty,这是一个我写的类,这个类主要是INotifyPropertyChanged,如果自己写ViewModel也好

ViewModel建立在ViewModel文件夹,一般少把类名称和文件夹一样

我们ViewModel主要是属性ElementTheme Theme,ElementTheme 有Default,Light,Dark,就是我们要把key叫light和dark,这样就可以绑定ViewModel修改

viewModel

    public class ViewModel : NotifyProperty
    {
        public ViewModel()
        {
        }

        public ElementTheme Theme
        {
            get
            {
                return _theme;
            }
            set
            {
                _theme = value;
                OnPropertyChanged();
            }
        }

        private ElementTheme _theme = ElementTheme.Light;
    }

我们绑定Page.RequestedTheme

先在xaml.cs写

 private ViewModel.ViewModel View { set; get; }=new ViewModel.ViewModel();

然后在xaml

<Page
    x:Class="NightDayThemeToggleButton.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:NightDayThemeToggleButton"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    RequestedTheme="{x:Bind View.Theme,Mode=OneWay}">

我们要看到变化,在xaml使用

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <Grid Background="{ThemeResource SystemBackgroundAltHighBrush}"> 
           <ToggleSwitch HorizontalAlignment="Center" Toggled="ToggleSwitch_OnToggled"></ToggleSwitch>
       </Grid>
    </Grid>

SystemBackgroundAltHighBrush是我们两个资源的,其中一个是白天,一个不是

        private void ToggleSwitch_OnToggled(object sender, RoutedEventArgs e)
        {
            View.Theme = View.Theme == ElementTheme.Light ? ElementTheme.Dark :
                ElementTheme.Light;
        }

运行可以看到点击就变成白天颜色,再点击就变为黑暗,这就是uwp切换主题,这样主题颜色很少,只有两个。

参见:https://embracez.xyz/xaml-uwp-themes/

我们总是会使用白天,夜间模式,那么我们需要切换主题,UWP切换主题简单

下面使用我做的一个按钮

夜间白天主题按钮

NightDayThemeToggleButton

我做的还有游戏键,这些都是可以简单使用的控件

这些控件放在https://github.com/lindexi/UWP,大家可以拿下来用。

做一个按钮,其实是修改

 <Style x:Key="NightDayThemeToggleButton" TargetType="CheckBox">
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>

                                    </VisualState>
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>
                             <Image x:Name="Light" Source="Assets/weather_sun.png"></Image>
                            <Image x:Name="Dark" Source="Assets/weather_moon.png"></Image>
                          </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

需要使用也简单,可以使用

<CheckBox Margin="16,193,0,75" Style="{StaticResource NightDayThemeToggleButton}" IsChecked="{x:Bind AreChecked,Mode=TwoWay}"></CheckBox>

这样复制我上面代码就好,如果想用我的控件,可以

<local:NightDayThemeToggleButton ></local:NightDayThemeToggleButton>

上面用到两张图片,一张是白天,一张是夜晚

首先我们是编辑副本,不知道这个在哪的可以去看我的入门http://blog.csdn.net/lindexi_gd/article/details/52041944,里面有很多连接

然后我们可以看到

<VisualState x:Name="UncheckedNormal">

我们把下面自带所有控件都删掉,然后添加两个Image,当然需要给他们x:Name

接着在上面添加透明度从1到0或从0到1,大概就是这样做。
