如果想要换成是如下图的这种导航

bubuko.com,布布扣   只需要将<mx:TabNavigator换成<mx:Accordion对应的标签即可

最后要说明的是ViewStack可不一样,如果我们直接将<mx:TabNavigator换成<mx:ViewStack那么只能显示一项的内容并且也没有导航条,需要添加一行导航条代码即可

在<mx:TabNavigator代码块之前加上<mx:LinkBar dataProvider="{mynavigator}" />

或者是<mx:TabBar dataProvider="{mynavigator}" />或者是

<s:ButtonBar dataProvider="{mynavigator}" />

或者是<mx:ToggleButtonBar dataProvider="{mynavigator}"/>

都会显示出很好的导航条效果,这个mynavigator指的是<mx:ViewStack id="navigator"的这个ID了
