一、先看效果

窗体移动

两个界面过渡效果

二、本文背景

YouTube Design com WPF 大神处习得，闹钟与新增闹钟界面切换效果。

三、代码实现

3.1 添加Nuget库

站长使用.Net Core 3.1创建的WPF工程，创建“Transitions”解决方案后，需要添加两个Nuget库：MaterialDesignThemes和MaterialDesignColors，上图的效果是使用该控件库实现的，非常强大。

3.2 工程结构

3.3 App.xaml添加MD控件样式

添加4个样式

 1 <Application x:Class="Transitions.App"
 2              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4              xmlns:local="clr-namespace:Transitions"
 5              StartupUri="MainWindow.xaml">
 6     <Application.Resources>
 7         <ResourceDictionary>
 8             <ResourceDictionary.MergedDictionaries>
 9                 <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml"/>
10                 <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml"/>
11                 <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml"/>
12                 <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Indigo.xaml"/>
13             </ResourceDictionary.MergedDictionaries>
14         </ResourceDictionary>
15     </Application.Resources>
16 </Application>

3.4 主窗体

MainWindow.xaml代码如下

 1 <Window x:Class="Transitions.MainWindow"
 2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
 5         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
 6         xmlns:local="clr-namespace:Transitions"
 7         mc:Ignorable="d"
 8         xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
 9         Title="" Height="600" Width="1080" ResizeMode="NoResize" 
10         WindowStartupLocation="CenterScreen" 
11         FontFamily="Microsoft YaHei UI Light"
12         WindowStyle="None" MouseDown="Window_MouseDown">
13     <Grid>
14         <materialDesign:Transitioner SelectedIndex="0" AutoApplyTransitionOrigins="True">
15             <Grid>
16                 <local:UserControlAlarms/>
17             </Grid>
18             <materialDesign:TransitionerSlide>
19                 <materialDesign:TransitionerSlide.BackwardWipe>
20                     <materialDesign:CircleWipe/>
21                 </materialDesign:TransitionerSlide.BackwardWipe>
22                 <materialDesign:TransitionerSlide.ForwardWipe>
23                     <materialDesign:SlideWipe Direction="Right"/>
24                 </materialDesign:TransitionerSlide.ForwardWipe>
25                 <local:UserControlNewAlarm/>
26             </materialDesign:TransitionerSlide>
27         </materialDesign:Transitioner>
28     </Grid>
29 </Window>

简单讲解：

1)需要先添加MD控件命名空间

xmlns:materialDesign=”http://materialdesigninxaml.net/winfx/xaml/themes”

2)设置无边框窗体样式并拖动

ResizeMode="NoResize" 
        WindowStartupLocation="CenterScreen" 
        FontFamily="Microsoft YaHei UI Light"
        WindowStyle="None" MouseDown="Window_MouseDown"

窗体拖动方法

private void Window_MouseDown(object sender, MouseButtonEventArgs e)
{
    DragMove();
}

3)设置闹钟列表用户控件和新增闹钟用户控件动画排版

默认显示闹钟列表用户控件local:UserControlAlarms，动画切换时显示新增闹钟用户控件local:UserControlNewAlarm

 1 <materialDesign:Transitioner SelectedIndex="0" AutoApplyTransitionOrigins="True">
 2             <Grid>
 3                 <local:UserControlAlarms/>
 4             </Grid>
 5             <materialDesign:TransitionerSlide>
 6                 <materialDesign:TransitionerSlide.BackwardWipe>
 7                     <materialDesign:CircleWipe/>
 8                 </materialDesign:TransitionerSlide.BackwardWipe>
 9                 <materialDesign:TransitionerSlide.ForwardWipe>
10                     <materialDesign:SlideWipe Direction="Right"/>
11                 </materialDesign:TransitionerSlide.ForwardWipe>
12                 <local:UserControlNewAlarm/>
13             </materialDesign:TransitionerSlide>
14         </materialDesign:Transitioner>

3.5 闹钟列表用户控件

代码简单，就是简单展示

 1 <UserControl x:Class="Transitions.UserControlAlarms"
 2              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4              xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
 5              xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
 6              xmlns:local="clr-namespace:Transitions"
 7              xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
 8              mc:Ignorable="d" 
 9              d:DesignHeight="450" d:DesignWidth="800">
10     <Grid>
11         <Grid.RowDefinitions>
12             <RowDefinition Height="200"/>
13             <RowDefinition Height="50"/>
14             <RowDefinition Height="*"/>
15         </Grid.RowDefinitions>
16         <materialDesign:ColorZone Grid.Row="0" Mode="Dark" VerticalAlignment="Stretch"
17                                   HorizontalAlignment="Stretch" VerticalContentAlignment="Stretch">
18             <TextBlock Text="闹钟" FontSize="50" Margin="80" VerticalAlignment="Center"/>
19         </materialDesign:ColorZone>
20         <Button Style="{DynamicResource MaterialDesignFloatingActionButton}"
21                 Command="{x:Static materialDesign:Transitioner.MoveNextCommand}"
22                 HorizontalAlignment="Left"
23                 VerticalAlignment="Bottom"
24                 Grid.Row="0" Grid.RowSpan="2" Margin="20">
25             <materialDesign:PackIcon Kind="AddAlarm"/>
26         </Button>
27         <ListView Grid.Row="2" Margin="10">
28             <ListViewItem Opacity="0.5">
29                 <Grid Width="300">
30                     <StackPanel>
31                         <TextBlock FontSize="30">05:01</TextBlock>
32                         <TextBlock FontSize="30" Opacity="0.8">关闭</TextBlock>
33                     </StackPanel>
34                     <ToggleButton HorizontalAlignment="Right" VerticalAlignment="Top" Margin="10"/>
35                 </Grid>
36             </ListViewItem>
37             <ListViewItem Opacity="0.5">
38                 <Grid Width="300">
39                     <StackPanel>
40                         <TextBlock FontSize="30">05:01</TextBlock>
41                         <TextBlock>晴 | 7点48分后响铃</TextBlock>
42                     </StackPanel>
43                     <ToggleButton IsChecked="True" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="10"/>
44                 </Grid>
45             </ListViewItem>
46         </ListView>
47     </Grid>
48 </UserControl>

3.6 新增闹钟用户控件

代码也不多，简单控件布局

 1 <UserControl x:Class="Transitions.UserControlNewAlarm"
 2              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
