问题描述

我正在 android 3.1 上开发一个应用程序，我有一个 Activity A，它有一个从 aSyncTask 扩展的子类，这个子类创建一个套接字并连接到服务器.我所有的沟通都很好.我收到消息并将命令发送到服务器，但是当我收到特定命令时，我必须启动第二个活动(活动 B)，但我不能丢失套接字并与服务器建立通信，而且我必须仍然能够从活动 B 到服务器接收和发送命令.我怎样才能做到这一点??请任何帮助！

I'm developing an application on android 3.1 and I have an Activity A that has a subclass extending from aSyncTask, this subclass create a socket and connect to a server. All my communication is good. I received messages and send commands to a server, but when I got a specific command I have to start a second activity (activity B) but I can't lost my socket and the establish communication with the server, plus I have to still able to receive and send commands from activity B to server. How can I do that?? Any help please!

推荐答案

我的方法是实现一个服务 并将所有网络连接代码移动/集中到服务中，对于所有想要使用套接字连接的活动，在 onCreate() 中绑定您的网络服务，然后在完成后在 onDestory() 中取消绑定

My approach is implementing a service and move/centralise all your network connection code into service, for all activities that want to use socket connection, bind your network service in onCreate() then after finish unbind it in onDestory()
