代碼如下

一、創(chuàng)建AnimationAudio.xaml代碼如下。

<ResourceDictionary?xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:controls="clr-namespace:WPFDevelopers.Controls"xmlns:helpers="clr-namespace:WPFDevelopers.Helpers"><ResourceDictionary.MergedDictionaries><ResourceDictionary?Source="Basic/ControlBasic.xaml"/><ResourceDictionary?Source="Basic/Animations.xaml"/></ResourceDictionary.MergedDictionaries><Style?TargetType="{x:Type?controls:AnimationAudio}"?BasedOn="{StaticResource?ControlBasicStyle}"><Setter?Property="Width"?Value="80"/><Setter?Property="Height"?Value="35"/><Setter?Property="Cursor"?Value="Hand"/><Setter?Property="Foreground"?Value="{DynamicResource?WhiteSolidColorBrush}"/><Setter?Property="Background"?Value="{DynamicResource?PrimaryNormalSolidColorBrush}"/><Setter?Property="Template"><Setter.Value><ControlTemplate?TargetType="{x:Type?controls:AnimationAudio}"><ControlTemplate.Resources><Storyboard?x:Key="PlayStoryboard"?RepeatBehavior="Forever"><ObjectAnimationUsingKeyFrames?Storyboard.TargetName="PathAudioTwo"?Storyboard.TargetProperty="(Path.Visibility)"><DiscreteObjectKeyFrame?KeyTime="0:0:0"?Value="{x:Static?Visibility.Hidden}"?/></ObjectAnimationUsingKeyFrames><ObjectAnimationUsingKeyFrames?Storyboard.TargetName="PathAudioThree"?Storyboard.TargetProperty="(Path.Visibility)"><DiscreteObjectKeyFrame?KeyTime="0:0:0"?Value="{x:Static?Visibility.Hidden}"?/></ObjectAnimationUsingKeyFrames><ObjectAnimationUsingKeyFrames?BeginTime="0:0:.3"?Duration="0:0:.4"?Storyboard.TargetName="PathAudioTwo"Storyboard.TargetProperty="(Path.Visibility)"><DiscreteObjectKeyFrame?KeyTime="0:0:0"?Value="{x:Static?Visibility.Visible}"?/></ObjectAnimationUsingKeyFrames><ObjectAnimationUsingKeyFrames?BeginTime="0:0:.7"?Duration="0:0:.4"?Storyboard.TargetName="PathAudioThree"Storyboard.TargetProperty="(Path.Visibility)"><DiscreteObjectKeyFrame?KeyTime="0:0:0"?Value="{x:Static?Visibility.Visible}"?/></ObjectAnimationUsingKeyFrames></Storyboard></ControlTemplate.Resources><Border?x:Name="PART_Border"?Background="{TemplateBinding?Background}"?CornerRadius="{TemplateBinding?helpers:ControlsHelper.CornerRadius}"SnapsToDevicePixels="True"?UseLayoutRounding="True"><Grid><Grid.ColumnDefinitions><ColumnDefinition/><ColumnDefinition/></Grid.ColumnDefinitions><StackPanel?Width="20"?Height="30"?HorizontalAlignment="Left"?Orientation="Horizontal"?Margin="10,0"RenderTransformOrigin=".5,.5"x:Name="PART_StackPanel"><Path?Data="{StaticResource?PathAudioOne}"?Width="4"?Height="6"?Stretch="Fill"?Fill="{TemplateBinding?Foreground}"/><Path?x:Name="PathAudioTwo"?Data="{StaticResource?PathAudioTwo}"?Width="6"?StrokeThickness="1.5"?Stroke="Transparent"?Margin="0,7"?Stretch="Fill"?Fill="{TemplateBinding?Foreground}"/><Path?x:Name="PathAudioThree"?Data="{StaticResource?PathAudioThree}"?Width="8"?Margin="-3,4"?Stretch="Fill"?Fill="{TemplateBinding?Foreground}"?StrokeThickness="2"?Stroke="Transparent"/></StackPanel><TextBlock?VerticalAlignment="Center"?Foreground="{TemplateBinding?Foreground}"FontSize="{DynamicResource?TitleFontSize}"Grid.Column="1"x:Name="PART_TextBlock"><Run?x:Name="PART_RunTimeLength"></Run></TextBlock></Grid></Border><ControlTemplate.Triggers><Trigger?Property="IsPlay"?Value="True"><Trigger.EnterActions><BeginStoryboard?x:Name="PlayBeginStoryboard"?Storyboard="{StaticResource?PlayStoryboard}"/></Trigger.EnterActions><Trigger.ExitActions><StopStoryboard?BeginStoryboardName="PlayBeginStoryboard"/></Trigger.ExitActions></Trigger><Trigger?Property="IsRight"?Value="True"><Setter?Property="Grid.Column"?TargetName="PART_TextBlock"?Value="0"/><Setter?Property="HorizontalAlignment"?TargetName="PART_TextBlock"?Value="Right"/><Setter?Property="Grid.Column"?TargetName="PART_StackPanel"?Value="1"/><Setter?Property="HorizontalAlignment"?TargetName="PART_StackPanel"?Value="Right"/><Setter?Property="RenderTransform"?TargetName="PART_StackPanel"><Setter.Value><TransformGroup><RotateTransform?Angle="180"/></TransformGroup></Setter.Value></Setter></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style></ResourceDictionary>

二、創(chuàng)建AnimationAudioe.cs代碼如下。

using?System; using?System.IO; using?System.Linq; using?System.Windows; using?System.Windows.Controls; using?System.Windows.Documents; using?System.Windows.Interop; using?WPFDevelopers.Helpers;namespace?WPFDevelopers.Controls {[TemplatePart(Name?=?RunTemplateName,?Type?=?typeof(Run))]public?partial?class?AnimationAudio?:?Control{const?string?RunTemplateName?=?"PART_RunTimeLength";private?Run?_run;private?TimeSpan?_timeSpan;private?IntPtr?_handle;private?AudioWindow?_win?=?null;static?string[]?mediaExtensions?=?{?".MP3",?".WAV"?};///?<summary>///?音頻路徑///?</summary>public?string?AudioPath{get?{?return?(string)GetValue(AudioPathProperty);?}set?{?SetValue(AudioPathProperty,?value);?}}public?static?readonly?DependencyProperty?AudioPathProperty?=DependencyProperty.Register("AudioPath",?typeof(string),?typeof(AnimationAudio),?new?PropertyMetadata(string.Empty));///?<summary>///?是否右側(cè)///?</summary>public?bool?IsRight{get?{?return?(bool)GetValue(IsRightProperty);?}set?{?SetValue(IsRightProperty,?value);?}}public?static?readonly?DependencyProperty?IsRightProperty?=DependencyProperty.Register("IsRight",?typeof(bool),?typeof(AnimationAudio),?new?PropertyMetadata(false));public?bool?IsPlay{get?{?return?(bool)GetValue(IsPlayProperty);?}set?{?SetValue(IsPlayProperty,?value);?}}public?static?readonly?DependencyProperty?IsPlayProperty?=DependencyProperty.Register("IsPlay",?typeof(bool),?typeof(AnimationAudio),?new?PropertyMetadata(false,?new?PropertyChangedCallback(OnIsPlayChanged)));private?static?void?OnIsPlayChanged(DependencyObject?d,?DependencyPropertyChangedEventArgs?e){bool?newValue?=?(bool)e.NewValue;var?animationAudio?=?d?as?AnimationAudio;if(newValue?!=?(bool)e.OldValue){if?(newValue){animationAudio.Play();}else{AudioPlayer.Stop();}}}static?AnimationAudio(){DefaultStyleKeyProperty.OverrideMetadata(typeof(AnimationAudio),?new?FrameworkPropertyMetadata(typeof(AnimationAudio)));}public?override?void?OnApplyTemplate(){base.OnApplyTemplate();_run?=?GetTemplateChild(RunTemplateName)?as?Run;if?(string.IsNullOrWhiteSpace(AudioPath))?return;if?(!File.Exists(AudioPath))?return;if?(!mediaExtensions.Contains(Path.GetExtension(AudioPath),?StringComparer.OrdinalIgnoreCase))?return;_timeSpan?=?AudioPlayer.GetSoundLength(AudioPath);if?(_timeSpan?==?TimeSpan.Zero)?return;_run.Text?=?$"{_timeSpan.Seconds.ToString()}\"";Width?=?80;if?(_timeSpan.Seconds?>?5){Width?+=?_timeSpan.Seconds;}}private?void?Play(){if(_win?!=?null){_win.Close();_win?=?null;}_win?=?new?AudioWindow{Width?=?0,Height?=?0,Left?=?Int32.MinValue,Top?=?Int32.MinValue,WindowStyle?=?WindowStyle.None,ShowInTaskbar?=?false,ShowActivated?=?false,};_win.Show();_win.StopDelegateEvent?+=?_win_StopDelegateEvent;_handle?=?new?WindowInteropHelper(_win).Handle;AudioPlayer.PlaySong(AudioPath,?_handle);}private?void?_win_StopDelegateEvent(){IsPlay?=?false;_win.Close();_win?=?null;}} }

三、新建AudioWindow.cs代碼如下。

using?System; using?System.Windows; using?System.Windows.Interop;namespace?WPFDevelopers.Controls {public?class?AudioWindow:Window{const?int?MM_MCINOTIFY?=?0x3B9;public?delegate?void?StopDelegate();public?event?StopDelegate?StopDelegateEvent;protected?override?void?OnSourceInitialized(EventArgs?e){base.OnSourceInitialized(e);HwndSource?hwndSource?=?PresentationSource.FromVisual(this)?as?HwndSource;if?(hwndSource?!=?null){hwndSource.AddHook(new?HwndSourceHook(this.WndProc));}}IntPtr?WndProc(IntPtr?hwnd,?int?msg,?IntPtr?wParam,?IntPtr?lParam,?ref?bool?handled){switch?(msg){case?MM_MCINOTIFY:StopDelegateEvent?.Invoke();break;}return?IntPtr.Zero;}} }

四、新建AnimationAudioExample.xaml代碼如下。

<UserControl?x:Class="WPFDevelopers.Samples.ExampleViews.AnimationAudioExample"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:WPFDevelopers.Samples.ExampleViews"xmlns:wpfdev="https://github.com/WPFDevelopersOrg/WPFDevelopers"mc:Ignorable="d"?d:DesignHeight="450"?d:DesignWidth="800"><UniformGrid?Columns="2"?x:Name="MyUniformGrid"><StackPanel?Orientation="Horizontal"><wpfdev:BreathLamp?Width="60"?Height="60"?LampEffect="Ripple"IsLampStart="true"Margin="10,0"><Ellipse?Width="50"?Height="50"><Ellipse.Fill><ImageBrush?ImageSource="pack://application:,,,/WPFDevelopers.Samples;component/Images/Breathe/0.jpg"/></Ellipse.Fill></Ellipse></wpfdev:BreathLamp><wpfdev:AnimationAudio?x:Name="AnimationAudioLeft"?MouseDown="AnimationAudioLeft_MouseDown"/></StackPanel><StackPanel?Orientation="Horizontal"HorizontalAlignment="Right"><wpfdev:AnimationAudio?x:Name="AnimationAudioRight"?IsRight?="true"?Background="{DynamicResource?SuccessSolidColorBrush}"Foreground="Black"MouseDown="AnimationAudioLeft_MouseDown"/><wpfdev:BreathLamp?Width="50"?Height="50"?LampEffect="Streamer"Background="LightGray"IsLampStart="True"Margin="10,0"><Ellipse?Width="43"?Height="43"><Ellipse.Fill><ImageBrush?ImageSource="pack://application:,,,/WPFDevelopers.Samples;component/Images/Chat/UserImages/yanjinhua.png"/></Ellipse.Fill></Ellipse></wpfdev:BreathLamp></StackPanel></UniformGrid> </UserControl>

六、新建AnimationAudioExample.xaml.cs下。

using?System; using?System.IO; using?System.Windows.Controls; using?WPFDevelopers.Controls; using?WPFDevelopers.Samples.Helpers;namespace?WPFDevelopers.Samples.ExampleViews {///?<summary>///?微信公眾號(hào):WPF開(kāi)發(fā)者///?</summary>public?partial?class?AnimationAudioExample?:?UserControl{public?AnimationAudioExample(){InitializeComponent();AnimationAudioLeft.AudioPath?=?Path.Combine(AppDomain.CurrentDomain.BaseDirectory,?"Resources",?"Audio",?"HelloWPFDevelopes_en.mp3");AnimationAudioRight.AudioPath?=?Path.Combine(AppDomain.CurrentDomain.BaseDirectory,?"Resources",?"Audio",?"HelloWPFDevelopes_zh.mp3");}private?void?AnimationAudioLeft_MouseDown(object?sender,?System.Windows.Input.MouseButtonEventArgs?e){var?animationAudio?=?sender?as?AnimationAudio;var?animationAudioList?=?ElementVisualTreeHelper.FindVisualChild<AnimationAudio>(MyUniformGrid);if?(animationAudioList?==?null)?return;if?(!animationAudio.IsPlay){animationAudioList.ForEach(h?=>{if?(h.IsPlay?&&?h?!=?animationAudio){h.IsPlay?=?false;}});animationAudio.IsPlay?=?true;}elseanimationAudio.IsPlay?=?false;}} }
