1.本文背景
系列文章最后一篇,一個完整的聊天界面垦江。當然只看效果,具體的項目需要將左側好友列表、中間會話列表浪读、右側聯(lián)系人簡況做成MVVM綁定的形式,做成模板才是一個完整的項目辛藻,本系列只是對界面的一個設計參考碘橘。
前面兩篇文章:
三篇文章最終效果如下:
2.代碼實現
使用 .Net CORE 3.1 創(chuàng)建名為 “Chat” 的WPF項目,添加 MaterialDesignThemes(3.0.1)吱肌、MaterialDesignColors(1.2.2)兩個Nuget庫痘拆,文中圖片已全部替換為站長網站logo圖片外鏈,直接Copy文中代碼即可運行氮墨,大家亦可下載原作者源碼研究學習纺蛆,文末會給出源碼下載鏈接。
2.1 引入MD控件樣式文件
使用MD控件的常規(guī)操作规揪,需要在App.xaml中引入4個樣式文件:
<Application x:Class="Chat.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Green.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
2.2 界面布局
純粹的布局代碼:整個界面分為左桥氏、中、右三塊粒褒,即好友列表识颊、好友會話、好友簡況三部分,實際項目祥款,需要將三塊做成模板進行MVVM綁定開發(fā)清笨,方便擴展。

2.2.3 窗體部分事件處理
后臺代碼
private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
private void Close_Click(object sender, RoutedEventArgs e)
{
this.Close();
}
2.2.4 新增兩個用戶控件
用于展示接收的會話和發(fā)送的會話,真實的項目可以做成一個桨昙,做成模板检号。
接收的會話用戶控件:
<UserControl x:Class="Chat.UserControlMessageReceived"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Chat"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800">
<Grid>
<Border Background="{StaticResource PrimaryHueDarkBrush}" CornerRadius="15 15 15 0" Margin="10 12">
<TextBlock Margin="15" TextWrapping="Wrap"
Text="你好,怎么聯(lián)系你蛙酪?" Foreground="White"/>
</Border>
<TextBlock Text="星期四下午5:45" HorizontalAlignment="Right" VerticalAlignment="Bottom" FontSize="10" Margin="10 -2"/>
</Grid>
</UserControl>
發(fā)送的會話用戶控件:
<UserControl x:Class="Chat.UserControlMessageSent"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Chat"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800">
<Grid>
<Border Background="Gray" CornerRadius="15 15 0 15" Margin="10 12">
<TextBlock Margin="15" TextWrapping="Wrap" Text="微信公眾號:Dotnet9齐苛,網站:https://dotnet9.com" Foreground="White"/>
</Border>
<TextBlock Text="星期四下午5:55" HorizontalAlignment="Right" VerticalAlignment="Bottom" FontSize="10" Margin="10 -2"/>
</Grid>
</UserControl>
