• 手把手教你 用 wpf 制作metro ProgressRing (Windows8 等待动画）

    效果图:

    还在羡慕metro的ProgressRing吗？

    wpf 也可以拥有

    首先说下思路，

    一共6个点围绕一直圆转，所以需要使用rotation动画 并且一直转下去。

    那么下面的问题就好解决了。

    首先是xaml 部分

    我们需要实现旋转动画：

    所以要用到这个：

    [html] view plaincopyprint?
     
    1. <DoubleAnimationUsingKeyFrames   
    2.       Storyboard.TargetProperty="(Ellipse.RenderTransform).(TransformGroup.Children)[2].(RotateTransform.Angle)">  
    3.                 <LinearDoubleKeyFrame Value="0" KeyTime="0:0:0"/>  
    4.                 <EasingDoubleKeyFrame Value="90" KeyTime="0:0:0.2">  
    5.                 </EasingDoubleKeyFrame>  
    6.                 <EasingDoubleKeyFrame Value="270" KeyTime="0:0:1.6">  
    7.                 </EasingDoubleKeyFrame>  
    8.                 <EasingDoubleKeyFrame Value="450" KeyTime="0:0:1.8">  
    9.                 </EasingDoubleKeyFrame>  
    10.                 <LinearDoubleKeyFrame Value="630" KeyTime="0:0:3.2"/>  
    11.                 <EasingDoubleKeyFrame Value="720" KeyTime="0:0:3.4">  
    12.                 </EasingDoubleKeyFrame>  
    13.                 <EasingDoubleKeyFrame Value="720" KeyTime="0:0:5.0">  
    14.                 </EasingDoubleKeyFrame>  
    15.             </DoubleAnimationUsingKeyFrames>  

    上面这一段是单个ellipse的运动轨迹，当然你需要在属性中设置他的中心点值

    代码如下：

    [html] view plaincopyprint?
     
    1. <Ellipse x:Name="el" Width="10" Height="10" Fill="White" Canvas.Left="73" Canvas.Top="57" >  
    2.             <Ellipse.RenderTransform>  
    3.                 <TransformGroup>  
    4.                     <ScaleTransform/>  
    5.                     <SkewTransform/>  
    6.                     <RotateTransform CenterX="-20" CenterY="-40"/>  
    7.                     <TranslateTransform/>  
    8.                 </TransformGroup>  
    9.             </Ellipse.RenderTransform>  
    10.         </Ellipse>  


     

    接下来的事情就好办了，我们需要他转1圈就消失 结束后也消失，所以需要控制透明度，

    [html] view plaincopyprint?
     
    1. <DoubleAnimationUsingKeyFrames   
    2.                         Storyboard.TargetProperty="Opacity">  
    3.                 <LinearDoubleKeyFrame Value="0" KeyTime="0:0:0"/>  
    4.                 <EasingDoubleKeyFrame Value="1" KeyTime="0:0:0.2">  
    5.                     <EasingDoubleKeyFrame.EasingFunction>  
    6.                         <BackEase EasingMode="EaseInOut"/>  
    7.                     </EasingDoubleKeyFrame.EasingFunction>  
    8.                 </EasingDoubleKeyFrame>  
    9.                 <EasingDoubleKeyFrame Value="1" KeyTime="0:0:1.6">  
    10.                 </EasingDoubleKeyFrame>  
    11.                 <EasingDoubleKeyFrame Value="1" KeyTime="0:0:1.8">  
    12.                 </EasingDoubleKeyFrame>  
    13.                 <LinearDoubleKeyFrame Value="1" KeyTime="0:0:3.2"/>  
    14.                 <EasingDoubleKeyFrame Value="0" KeyTime="0:0:3.5">  
    15.                     <EasingDoubleKeyFrame.EasingFunction>  
    16.                         <BackEase EasingMode="EaseOut"/>  
    17.                     </EasingDoubleKeyFrame.EasingFunction>  
    18.                 </EasingDoubleKeyFrame>  
    19.                 <EasingDoubleKeyFrame Value="0" KeyTime="0:0:5.0">  
    20.                 </EasingDoubleKeyFrame>  
    21.             </DoubleAnimationUsingKeyFrames>  


     

    最终把一个圆变成多个圆的工作 就交给代码了，需要一点点小技巧 以下使用.net 4.5实现 其他版本可以吧Task.Delay 替换成Thread.Sleep
