我的项目使用flex mobile 4.5使用套接字..接收庞大的数据流.. 并且ui应用程序就像挂起...在所有过程数据完成之前的一分钟 如何在as3中使用socket中的多线程？任何样本？ 任何诡计？制作后台流程
吼叫我的代码

如果您遇到旧版本的Flash播放器，则需要在AS3中搜索谷歌＆＃34;绿色线程＆＃34;。
如果您使用的是较新版本的播放器，或Adobe AIR用于桌面和设备，则可以使用多线程，通过＆＃34; actionscript worker＆＃34 ;.
答案 1 :(得分：-2)
Flash和Flex引擎只能在一个线程中运行 - 无法进行多线程或并行编程。最接近的是Flash的Event系统;您可以异步加载资产。我无法确定你是否这样做，因为你的代码有点难以理解。
我的建议 - 将你的装载包装在另一个班级。这应该有助于将其与用户界面分开，这可能会改善您的情况和代码质量。
