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:
- <DoubleAnimationUsingKeyFrames
- Storyboard.TargetProperty="(Ellipse.RenderTransform).(TransformGroup.Children)[2].(RotateTransform.Angle)">
- <LinearDoubleKeyFrame Value="0" KeyTime="0:0:0"/>
- <EasingDoubleKeyFrame Value="90" KeyTime="0:0:0.2">
- </EasingDoubleKeyFrame>
- <EasingDoubleKeyFrame Value="270" KeyTime="0:0:1.6">
- </EasingDoubleKeyFrame>
- <EasingDoubleKeyFrame Value="450" KeyTime="0:0:1.8">
- </EasingDoubleKeyFrame>
- <LinearDoubleKeyFrame Value="630" KeyTime="0:0:3.2"/>
- <EasingDoubleKeyFrame Value="720" KeyTime="0:0:3.4">
- </EasingDoubleKeyFrame>
- <EasingDoubleKeyFrame Value="720" KeyTime="0:0:5.0">
- </EasingDoubleKeyFrame>
- </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:
- <Ellipse x:Name="el" Width="10" Height="10" Fill="White" Canvas.Left="73" Canvas.Top="57" >
- <Ellipse.RenderTransform>
- <TransformGroup>
- <ScaleTransform/>
- <SkewTransform/>
- <RotateTransform CenterX="-20" CenterY="-40"/>
- <TranslateTransform/>
- </TransformGroup>
- </Ellipse.RenderTransform>
- </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,
- <DoubleAnimationUsingKeyFrames
- Storyboard.TargetProperty="Opacity">
- <LinearDoubleKeyFrame Value="0" KeyTime="0:0:0"/>
- <EasingDoubleKeyFrame Value="1" KeyTime="0:0:0.2">
- <EasingDoubleKeyFrame.EasingFunction>
- <BackEase EasingMode="EaseInOut"/>
- </EasingDoubleKeyFrame.EasingFunction>
- </EasingDoubleKeyFrame>
- <EasingDoubleKeyFrame Value="1" KeyTime="0:0:1.6">
- </EasingDoubleKeyFrame>
- <EasingDoubleKeyFrame Value="1" KeyTime="0:0:1.8">
- </EasingDoubleKeyFrame>
- <LinearDoubleKeyFrame Value="1" KeyTime="0:0:3.2"/>
- <EasingDoubleKeyFrame Value="0" KeyTime="0:0:3.5">
- <EasingDoubleKeyFrame.EasingFunction>
- <BackEase EasingMode="EaseOut"/>
- </EasingDoubleKeyFrame.EasingFunction>
- </EasingDoubleKeyFrame>
- <EasingDoubleKeyFrame Value="0" KeyTime="0:0:5.0">
- </EasingDoubleKeyFrame>
- </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
