我有一个具有以下状态的项目渲染器：

<s:states>
    <s:State name="normal"/>
    <s:State name="hovered"/>
    <s:State name="selected"/>
</s:states>

我试图在悬停和选择时更改项目的背景颜色。我在 Item 渲染器开始标记中添加了以下几行：

contentBackgroundColor.hovered="0xff0018"
contentBackgroundColor.selected="0xffff11"

除了默认项目渲染器行为（灰色）之外，悬停或选择时不会发生任何事情。如果我说增加图像的宽度：

width.hovered="100"

图像按预期调整大小，我怎样才能达到我想要的效果？

把它放在 CSS 中：

s|ItemRenderer:hovered {
 contentBackgroundColor: #ff0018;
}

您应该在 css 中使用：

.myItemRendererStyleName:selected #idOflabelInItemRenderer { contentBackgroundColor:#ff0000; }

在 mxml 中： <s:ItemRenderer styleName="myItemRendererStyleName" .... />

<s:Label id="idOflabelInItemRenderer" includeIn="normal,selected" />

这行得通

<s:GridItemRenderer currentState="normal" >
<fx:Script>
    <![CDATA[
        import mx.events.FlexEvent;

        protected function state1_enterStateHandler(event:FlexEvent):void{
            bc.setStyle("backgroundColor",0xff0018);
        }

    ]]>
</fx:Script>
<s:states>
    <s:State name="normal"/>
    <s:State enterState="state1_enterStateHandler(event)" name="myState"/>
    <s:State name="selected"/>
</s:states>

<s:BorderContainer id="bc" left="0" right="0" height="{this.height}"/>
<s:Button click="this.currentState = 'prova'"/>
