<mx:LinkBar id="lnkBar" backgroundAlpha="0" backgroundColor="black" bottom="0" itemClick="lnkBar_itemClickHandler(event)">
            <mx:dataProvider>
                <s:ArrayCollection>
                    <fx:String>Resource Management</fx:String>
                    <fx:String>Standard Reports</fx:String>
                    <fx:String>Clear Selected State</fx:String>
                </s:ArrayCollection>
            </mx:dataProvider>
        </mx:LinkBar>

而不是"backgroundAlpha"或"backgroundColor",使用"contentBackgroundAlpha"或"contentBackgroundColor".
