Android 如何将数据从ServerSocket发送到Socket？

在问了这么多关于android socket编程的问题并从stackoverflow的成员那里得到了有价值的答案之后，我可以使用socket通过wifi连接两台设备，完成一个运行良好的程序。 谢谢大家。 但是我仍然有一些问题

我已经完成了其中的程序 **数据可以从客户端发送，也可以在serverSocket接收** 但我仍然不知道如何从服务器发送可以在客户端接收的数据

服务器套接字代码

private OnClickListener bt_sendListner = new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub

        String msg=et_msg.getText().toString();
        Log.d("Msg", msg);
        Thread threadsendmsg = new Thread(new Threadsendmsg(msg));
        threadsendmsg.start();

    }
};



public class Threadsendmsg implements Runnable{

    String msg;

    public Threadsendmsg(String msg) {
        // TODO Auto-generated constructor stub
      this.msg=msg;


    }

    public void run() {
        // TODO Auto-generated method stub
         try {

             Looper.prepare();
                Log.d("Msg", "Inside the thread");


             //connected = true; 
                while (true) {
                    try {

                        Log.d("Msg", "Msg to be sent");

                        PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(serverSocket.accept().getOutputStream())), true);
                            // where you issue the commands
                            out.println("Client: "+msg);
                            Log.d("Msg", "Msg sent"+out.toString());

                            break;
                    } catch (final Exception e) {
                        handler.post(new Runnable() {

                            public void run() {
                                // TODO Auto-generated method stub
                    tv_chatbox.setText("S: Error= "+ e.getMessage());
                             Log.d("Msg", e.getMessage());   
                            }
                        });
                    }
                }
              //  socket.close();
              //  console.append("\nC: Closed.");
            } catch (final Exception e) {
                handler.post(new Runnable() {

                    public void run() {

                        // TODO Auto-generated method stub

                    }
                });

           //   connected = false;
            }



    }

*ServerSocket类中没有像ServerSocket.getOutputStream（）那样的方法。*我使用的是client socket…

客户端和服务器都使用相同的socket类。但客户端手动创建套接字实例并连接到服务器。另一方面，服务器在某个端口侦听，当客户端连接时，将创建服务器的套接字并从方法accept（）返回。 在您的代码中，您可以使用

client.getOutputStream();

Threadsendmsg类做什么？是客户端吗？它将消息发送到服务器。我尝试了服务器套接字类将消息发送到客户端的相同方法，但不起作用…请同时输入客户端代码，我已经搜索了很多，但我已经花了整整一周的时间在它上面，但仍然无法实现。

ServerSockets

无法发送或接收数据。这个问题没有意义。@EJP-这个问题不是没有意义的，它只是因为误解了ServerSocket和接受连接后产生的服务器端套接字之间的区别。对此作出解释比结束问题更有成效。
