我创建了一个按钮,当处于不同的状态时,它会改变它的外观,当按下按钮时我就这样做了(作为一个例子):
<vsm:VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="border" Storyboard.TargetProperty="(UIElement.Background).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00" Value="Green"/>
</ColorAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="border" Storyboard.TargetProperty="(UIElement.RenderTransform). (TransformGroup.Children)[0].(ScaleTransform.ScaleX)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0.94"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="border" Storyboard.TargetProperty="(UIElement.RenderTransform). (TransformGroup.Children)[0].(ScaleTransform.ScaleY)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0.94"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</vsm:VisualState>
有没有办法可以用更少的代码完成这项工作?我只是希望刻度和颜色在按下时立即变为绿色,有没有办法不使用关键帧?
感谢您的帮助!

这可以写成:
<ColorAnimation Duration="0" To="Green" Storyboard.TargetName="border" Storyboard.TargetProperty="(UIElement.Background).(SolidColorBrush.Color)" />
<DoubleAnimation Duration="0" To="0.94" Storyboard.TargetName="border" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)" />
<DoubleAnimation Duration="0" To="0.94" Storyboard.TargetName="border" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)" />
一般动画更容易理解和使用,并且很少有框架动画可用于一般动画的情况。
