Question

大家。我希望有人可以帮助我。我正在做一个AIR应用程序项目，需要嵌入一个由Encore生成的swf文件，该文件又嵌入一个视频（F4V）文件。使用Loader对象加载时出现以下错误：

 TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at mx.managers::FocusManager/activate()
    at spark.components::Application/initManagers()
    at spark.components::Application/initialize()
    at EncoreSWF/initialize()
    at mx.managers.systemClasses::ChildManager/childAdded()
    at mx.managers.systemClasses::ChildManager/initializeTopLevelWindow()

    at flash.events::EventDispatcher/dispatchEvent()
    at mx.preloaders::Preloader/timerHandler()
    at flash.utils::Timer/_timerDispatch()
    at flash.utils::Timer/tick()

我非常了解Flash Professional，但Flash Builder完全没有。以下是我的代码：

    import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.Event;

var showBusinessPlay:Loader = new Loader;
showBusinessPlay.x = 0;
showBusinessPlay.y = 0;
showBusinessPlay.width = 1024;
showBusinessPlay.height = 768;
showBusinessPlay.visible = true;
showBusinessPlay.load(new URLRequest("TestFlash/flashdvd.swf"));
showBusinessPlay.addEventListener(Event.COMPLETE,addToStage);
function addToStage(event:Event):void{
    stage.addChild(showBusinessPlay);
}

如果有任何方法可以做到这一点，我知道会有，请帮助我。如果需要使用Flash Builder和swc文件，请告诉我必须遵循的步骤。

我认为这与SWF没有任何关系。你能告诉我们更多的代码吗？

这条线不正确：

var showBusinessPlay:Loader = new Loader;

它需要

var showBusinessPlay:Loader = new Loader();

将带有外部视频的Adobe Encore生成的.swf文件嵌入到使用Flash Pro的Adobe AIR应用程序中
