如何以编程方式设置组件SpinnerList（Flex移动）的旋转，以便它可以旋转几秒钟，然后停在选定的指数？

 私有函数scrollToIndex（索引：INT，animationDuration：INT = 1000）：无效{
如果（（指数= -1）及！＆安培;！（list.layout =空））{
VAR spDelta：点= list.dataGroup.layout.getScrollPositionDeltaToElement（指数）;
如果（（spDelta =空）及！＆安培;！（spDelta.y = 0））{
VAR目标：DataGroup的= list.dataGroup;
VAR动画：的animateProperty =新的animateProperty（目标）;
animation.property =verticalScrollPosition的;
animation.duration = animationDuration;
animation.toValue = target.verticalScrollPosition + spDelta.y;
animation.play（）;

}
 

} }

How to programmatically set the spin of component SpinnerList (Flex mobile) so that it can spin for a few seconds and then stopped at selected index?

private function scrollToIndex(index:int, animationDuration:int = 1000):void {
if ((index != -1) && (list.layout != null)) {
var spDelta:Point = list.dataGroup.layout.getScrollPositionDeltaToElement(index);
if ((spDelta != null) && (spDelta.y != 0)) {
var target:DataGroup = list.dataGroup;
var animation:AnimateProperty = new AnimateProperty(target);
animation.property = "verticalScrollPosition";
animation.duration = animationDuration;
animation.toValue = target.verticalScrollPosition + spDelta.y;
animation.play();

}

} }
