假设我已经创建了活动A.客户端TCP套接字我想发送的Socket到活动B.现在，在活动B，根据一定的条件，我将关闭套接字。问题是intent.putExtra（）亘古不支持发送插槽。那么怎么办呢？

Assume that i have created a client TCP Socket in Activity A. I want to send that Socket to Activity B. Now in Activity B, based on some conditions i will close that socket. The problem is intent.putExtra() doesnot support sending sockets. So how to do that?

推荐答案

如果你认为有多个活动拥有一个插座，然后他们都不应该自己的插座。别的东西，像服务，应该是负责管理插槽。在这种情况下，活动A可以启动服务做插座的工作，而当插槽不再需要b活动可以停止该服务。

If you think that there are multiple activities that "own" a socket, then none of them should "own" the socket. Something else, like a Service, should be in charge of managing the socket. In this case, Activity A could start a Service to do the socket work, and Activity B can stop the service when the socket is no longer needed.

否则，如果这些活动是紧耦合的，它们不应该是独立的活动。活动的目的是松散耦合，类似于网页在一个Web应用程序。

Otherwise, if those activities are that tightly coupled, they should not be separate activities. Activities are designed to be loosely coupled, akin to Web pages in a Web app.
