HSlider已针对移动设备进行了优化，但VSlider没有 - 正如您在此处看到的：
同时，以移动为主题的HSliderSkin.as看起来非常简单。
所以我在我非常简单的测试项目中将该文件复制到“VSliderSkin.as”中，并且 -
用“VSlider”替换了对“HSlider”的明显引用
在 measure() 方法中交换了“宽度”<->“高度”
在 layoutContents() 中交换了 "width" <-> "height" 和 "x" <-> "y"
SlideApp.mxml（只需添加到一个空白的 Flex 移动项目）：
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
applicationDPI="160">
<s:VSlider
skinClass="VSliderSkin"
horizontalCenter="0"
height="80%" />
<s:HSlider
skinClass="spark.skins.mobile.HSliderSkin"
width="100%"
bottom="10" />
</s:Application>
VSliderSkin.as（放入与 SlideApp.as 相同的目录）：

当然这不起作用，但是非常接近并且拇指垂直移动 - 它应该：
有人知道如何完成我的手机皮肤吗？
我也应该创建HSliderTrackSkin.as的副本吗？或者也许可以（ab）在这里使用非移动VSliderTrackSkin.mxml ？
