flash - Flex Mobile StageWebView 不显示

Question

我在 Flex Mobile 4.6 (Flash Builder 4.6) 上显示 StageWebView 时遇到问题，当我动态创建它时，事件被正确调用但没有任何内容可见，这是我的代码:

<components:View xmlns:fx="http://ns.adobe.com/mxml/2009" 
             xmlns:s="library://ns.adobe.com/flex/spark" 
             xmlns:components="spark.components.*" 
             actionBarVisible="false"
             title="ActivityView"
             creationComplete="init()"
             >
<components:layout>
    <s:BasicLayout/>
</components:layout>
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<fx:Script>
    <![CDATA[
        private var webView:StageWebView;

        protected function init():void {
            webView = new StageWebView();
            webView.stage = this.stage;
            webView.viewPort = new Rectangle(5, 20, screen.width-10, screen.height-40);
            webView.addEventListener(Event.COMPLETE, onURLLoadComplete);
            webView.addEventListener(LocationChangeEvent.LOCATION_CHANGE, onLocationChange);
            webView.loadURL("http://google.com");
        }

        protected function onURLLoadComplete(event:Event):void
        {
            trace("Load Complete");
        }

        protected function onLocationChange(event:LocationChangeEvent):void
        {
            trace("Location change: " + event.location);
        }

    ]]>
</fx:Script>
</components:View>

Answer 1

webView.stage = this.stage;

当它在creationComplete 事件处理程序中时，this.stage 仍然为空。

您应该将 init() 放在 addedToStage 事件处理程序中。
