1. 本文背景

继续 MaterialDesignThemes 开源控件库学习，尤其是它的图标组件，本文设计的音乐播放器主界面设计使用该组件较多。

2. 代码实现

使用 .NET CORE 3.1 创建名为 “Player” 的WPF模板项目，添加1个Nuget库：MaterialDesignThemes.3.1.0-ci981。

解决方案主要文件目录组织结构：

  • Player

    • App.xaml
    • MainWindow.xaml
      • MainWindow.xaml.cs

2.1 App.xaml文件引入样式

文件【App.xaml】，在 StartupUri 中设置启动的视图【MainWindow.xaml】，并在【Application.Resources】节点增加 MaterialDesignThemes库的样式文件：

<Application x:Class="Player.App"

             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:local="clr-namespace:Player"

             StartupUri="MainWindow.xaml">

    <Application.Resources>

        <ResourceDictionary>

            <ResourceDictionary.MergedDictionaries>

                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />

                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />

                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml" />

                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Indigo.xaml" />

            </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>

    </Application.Resources>

</Application>

2.2 MainWindow.xaml音乐播放器主窗体

文件【MainWindow.xaml】，设计主界面，源码如下：

<Window x:Class="Player.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        MouseLeftButtonDown="MoveWindow_MouseLeftButtonDown"

简单说明：

  1. 界面中按钮使用开源控件库MD的【PackIcon】组件，统一风格使用了自定义前景色【Foreground】。
  2. 列表控件【ListView】用于展示音乐播放列表，方便演示，每一项写死的，实际使用需要封装成模板，方便MVVM数据绑定。
  3. 列表控件【ListView】的竖直滚动条样式进行了修改，可看资源定义，改为了整体和黑色背景比较搭配的白色。

下面是后台代码：文件【MainWindow.xaml.cs】，关闭窗体、窗体移动、上一首及下一首按钮简单点击等事件处理，因为是演示事例，所以写的简单。

using System.Windows;

using System.Windows.Input;

namespace Player

{

    /// <summary>

    /// Interaction logic for MainWindow.xaml

    /// </summary>

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

        }

        private void ButtonFechar_Click(object sender, RoutedEventArgs e)

        {

            Application.Current.Shutdown();

        }

        private void Proxima_Click(object sender, RoutedEventArgs e)

        {

            if (c1.Offset >= 0)

            {

                c1.Offset -= 0.01;

                c2.Offset -= 0.01;

            }

            else

            {

                c1.Offset = 1;

                c2.Offset = 0.89;

            }

        }

        private void Anterior_Click(object sender, RoutedEventArgs e)

        {

            if (c2.Offset <= 1)

            {

                c1.Offset += 0.01;

                c2.Offset += 0.01;

            }

            else

            {

                c1.Offset = 0.11;

                c2.Offset = 0;

            }

        }

        private void MoveWindow_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)

        {

            DragMove();

        }

    }

}
