Android客户端与Eclipse服务器端的Socket通信

Server端代码

用来实现客户端socket的监听

 1 package MyServer;
 2 
 3 import java.io.BufferedReader;
 4 import java.io.BufferedWriter;
 5 import java.io.IOException;
 6 import java.io.InputStreamReader;
 7 import java.io.OutputStreamWriter;
 8 import java.net.ServerSocket;
 9 import java.net.Socket;
10 import java.util.Vector;
11 
12 import javax.swing.JOptionPane;
13 
14 public class MyServerSocket
15 {
16     private Vector<ChatSocket> vector=new Vector<ChatSocket>();//存放所有的客户端socket
17     public MyServerSocket()
18     {
19         try
20         {
21             ServerSocket serverSocket=new ServerSocket(13345);//服务端开启对端口13345的监听
22             while(true)
23             {
24               Socket socket=serverSocket.accept();//服务器端提供与客户端相对应的socket
25               JOptionPane.showMessageDialog(null, "已经有客户端连入");
26               ChatSocket cs=new ChatSocket(socket,vector);//对每一个客户端都提供一个ChatSocket类来进行信息的交互
27               add(cs);
28               cs.start();
29             }
30         } catch (IOException e)
31         {
32             // TODO 自动生成的 catch 块
33             e.printStackTrace();
34         }
35     }
36     public void add(ChatSocket csSocket)//服务器端添加每一个客户端socket
37     {
38         vector.add(csSocket);
39     }
40     public static void main(String[]args)
41     {
42         new MyServerSocket();
43     }
44 }

ChatSocket类，继承Thread线程类，进行与每个客户端进行信息交互的任务
