十年河东，十年河西，莫欺少年穷

学无止境，精益求精

实现的效果：

wpf + MaterialDesign + Prism8 实现导航功能_xml

 1、初始化Prism 

1.1、项目引入如下包

wpf + MaterialDesign + Prism8 实现导航功能_App_02

 1.2、按照Prism规则，项目中创建如下文件夹

wpf + MaterialDesign + Prism8 实现导航功能_App_03

 Prism 规则：必须将窗体放入 Views文件夹中，窗体名称必须以View结尾，必须将数据上下文放入ViewModels文件夹中，上下文类必须以Model结尾

另外两个文件夹分为存放用户控件 及 用户控件使用的数据类

新建窗体MainView 和 MainViewModel、新建用户控件IndexView 和 IndexViewModel、新建用户控件UserView 和 UserViewModel （其实用户控件及上下文类无需遵守Prism规则）

1.3、初始化App.xaml 及 App.cs 

App.cs

using Prism.DryIoc;
using Prism.Ioc;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;
using WpfApp.UserControls;
using WpfApp.ViewModels;
using WpfApp.Views;

namespace WpfApp
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : PrismApplication
    {
        protected override Window CreateShell()
        {
            return Container.Resolve<MainView>();
        }

        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
            containerRegistry.RegisterForNavigation<IndexView, IndexViewModel>();
            containerRegistry.RegisterForNavigation<UserView, UserViewModel>();
        }
    }
}

View Code

App.Xaml

<Prism:PrismApplication x:Class="WpfApp.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:Prism="http://prismlibrary.com/"
             xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
             xmlns:local="clr-namespace:WpfApp" >
    <Application.Resources>
         
    </Application.Resources>
</Prism:PrismApplication>

View Code

App.cs 中重新了二个方法，第一个方法为设定启动窗口，第二个方法为注册导航（两个用户控件为填充内容）

App.xaml 中引入 Prism 命名空间，及改造根节点

2、App.xaml 引入MaterialDesign

 MaterialDesign 的GitHub地址为： https://github.com/MaterialDesignInXAML/MaterialDesignInXamlToolkit 

按照文档引入MaterialDesign，App.xaml 变更为：

<Prism:PrismApplication x:Class="WpfApp.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:Prism="http://prismlibrary.com/"
             xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
             xmlns:local="clr-namespace:WpfApp" >
    <Application.Resources>

            <ResourceDictionary.MergedDictionaries>
                <materialDesign:BundledTheme BaseTheme="Light" PrimaryColor="DeepPurple" SecondaryColor="Lime"  />
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            </ResourceDictionary.MergedDictionaries>

            <!--自定义样式 样式名:MyListBoxItemStyle,样式挂载：ListBoxItem-->
            <Style x:Key="MyListBoxItemStyle" TargetType="ListBoxItem">
                <!--自定义高度-->
                <Setter Property="MinHeight"
           Value="48" />
                <Setter Property="Template">
                    <Setter.Value>
                        <!--影响属性 ListBoxItem-->
                        <ControlTemplate TargetType="{x:Type ListBoxItem}">
                            <Grid>
                                <Border x:Name="borderHeader" />
                                <Border x:Name="border" />
                                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalAlignment}"
                                     VerticalAlignment="{TemplateBinding VerticalAlignment}"/>
                            </Grid>

                            <!--触发器-->
                            <ControlTemplate.Triggers>
                                <!--ListBoxItem点击时触发-->
                                <Trigger Property="IsSelected" Value="True">
                                    <Setter Property="BorderThickness"
                               TargetName="borderHeader"  Value="4,0,0,0"/>
                                    <Setter Property="BorderBrush"
                               TargetName="borderHeader"
                               Value="{DynamicResource PrimaryHueLightBrush}" />
                                    <Setter TargetName="border"
                               Property="Background"
                               Value="{DynamicResource PrimaryHueLightBrush}" />
                                    <Setter TargetName="border"
                               Property="Opacity"
                               Value="0.4" />
                                </Trigger>
                                <!--鼠标悬停触发器触发器-->

                                <Trigger Property="IsMouseOver" Value="True">

                                    <Setter TargetName="border"
                               Property="Background"
                               Value="{DynamicResource PrimaryHueLightBrush}" />

                                    <Setter TargetName="border"
                               Property="Opacity"
                               Value="0.1" />

                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

        </ResourceDictionary>
    </Application.Resources>
</Prism:PrismApplication>

2.1、检测是否成功引入 MaterialDesign 

在 MainView 中添加一个按钮

<Grid>
        <Button  Content="检测是否成功引入" FontSize="30" Height="80" Width="280"/>
    </Grid>

出现如下样式，则证明引入成功

 3、改造MainView

先贴出MainView.xaml 代码如下：
