Apache flex 将s customskin设置为flex移动应用程序会使所有组件都消失

我正在尝试向我的应用程序添加一个带有背景图像的自定义皮肤，它完全适合任何设备的整个屏幕。 这是皮肤：

     <?xml version="1.0" encoding="utf-8"?>


    <s:Skin name="CustomMainSkin"
    xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"
    alpha.disabled="0.5" >
<s:states>
    <s:State name="normal" />
    <s:State name="disabled" />
</s:states>

<fx:Metadata>
    <![CDATA[ 
    [HostComponent("spark.components.Application")]
    ]]>
</fx:Metadata> 

<!-- fill -->
<s:BitmapImage id="img"
               source="assets/background.jpg"
               scaleMode="stretch"
               fillMode="scale"
               smooth="true"
               left="0" right="0"
               top="0" bottom="0" />

<s:Group id="contentGroup" left="0" right="0" top="0" bottom="0" minWidth="0" minHeight="0" />

如果我在应用程序上设置皮肤，一切看起来都很好，图像会根据屏幕需要调整大小，但所有组件都会消失，我无法编辑任何视图

      <s:TabbedViewNavigatorApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
                              xmlns:s="library://ns.adobe.com/flex/spark" applicationDPI="240"
                              xmlns:components="views.*"
                              creationComplete="removeTab1DefaultView(event)"
skinClass="skins.CustomMainSkin"     >

<s:ViewNavigator label="Main view" firstView="views.MainView"/>
<s:ViewNavigator label="Online Rankings" firstView="views.RankingsOnline"/>
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
      </s:TabbedViewNavigatorApplication>

我尝试使用SkinnableContainer直接在视图中设置蒙皮。组件以这种方式可见，但图像不会调整大小，并且比屏幕大得多

        <?xml version="1.0" encoding="utf-8"?>
        <s:View xmlns:fx="http://ns.adobe.com/mxml/2009" 
    xmlns:s="library://ns.adobe.com/flex/spark" title="MainView"
    actionBarVisible="false"
    tabBarVisible="false"
    >

        <s:SkinnableContainer skinClass="skins.CustomMainSkin" >
<s:NavigatorContent id="gameBoard" >
</s:NavigatorContent>
<s:Group x="27" y="133" width="297" height="388">
    <s:Button left="33" right="36" top="39" bottom="281" label="Start Game"
              horizontalCenter="-2" verticalCenter="-121" click="button1_clickHandler(event)"/>
    <s:Button x="34" y="146" width="228" label="Rankings" click="rankingsAction(event)"/>
    <s:Button x="32" y="252" width="228" label="Quit"/>
</s:Group>
</s:SkinnableContainer>
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>  

     </s:View>

我怎样才能做到这一点？这似乎真的很难而且不自然

谢谢

下面是一个简单皮肤的BG图像示例。 下面是使用它的代码

用法：

             skinClass="WorkspaceSkin">

我认为您正在尝试在TabbedViewNavigatorApplication类上设置外观。对吗？你可能想在你的文本中澄清这一点。我不清楚到底是什么部件消失了。但是，你的皮肤看起来确实很稀疏。也许您应该扩展TabbedViewNavigatorApplicationSkin类，而不是新皮肤的皮肤。我敢打赌，默认皮肤包含用于调整大小/定位/布局孩子的代码，而您的新皮肤没有这样做。另请参阅有关此问题的评论：
