           <mx:Script>
              <![CDATA[
              import mx.controls.Button;

您可以使用以下代码：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application layout="absolute" xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Script>
    <![CDATA[
        public function clickhandler(event:Event):void
        {
            fruitAnimation.play();
        }
    ]]>
    </mx:Script>

    <mx:Move id="fruitAnimation" target="{fruitImage}" xTo="375" yTo="450" />

    <mx:Canvas backgroundColor="#A9C0E7" borderStyle="solid" height="800" id="myCanvas" width="800">
        <mx:Image click="clickhandler(event)" height="50" id="fruitImage" source="@Embed(source='fruits.jpg')"
            width="50" x="100" y="10" />
        <mx:Image height="200" source="@Embed(source='box.jpg')" width="200" x="300" y="350" />
    </mx:Canvas>
</mx:Application>

如果要添加抛物线运动，可以使用以下代码：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application layout="absolute" xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Script>
    <![CDATA[
        import mx.effects.easing.Quadratic;
        public function clickhandler(event:Event):void
        {
            fruitAnimation.play();
        }
    ]]>
    </mx:Script>

    <mx:Parallel id="fruitAnimation" target="{fruitImage}">
        <mx:AnimateProperty property="x" toValue="375" easingFunction="{Quadratic.easeOut}" />
        <mx:AnimateProperty property="y" toValue="450" />
    </mx:Parallel>

    <mx:Canvas backgroundColor="#A9C0E7" borderStyle="solid" height="800" id="myCanvas" width="800">
        <mx:Image click="clickhandler(event)" height="50" id="fruitImage" source="@Embed(source='fruits.jpg')"
            width="50" x="100" y="10" />
        <mx:Image height="200" source="@Embed(source='box.jpg')" width="200" x="300" y="350" />
    </mx:Canvas>
</mx:Application>

希望这会有所帮助！

在http://www.greensock.com/tweenlite/下载 tweenLite 库

那么你可以使用下面的代码：

public function clickhandler(e:Event):void
{
    TweenLite.to(e.target, 0.5, {x: 300, y: 350});
}
