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

 package MyServer;

 import java.io.BufferedReader;
 import java.io.BufferedWriter;
 import java.io.IOException;
 import java.io.InputStreamReader;
 import java.io.OutputStreamWriter;
 import java.net.ServerSocket;
 import java.net.Socket;
 import java.util.Vector;

 import javax.swing.JOptionPane;

 public class MyServerSocket
 {
     private Vector<ChatSocket> vector=new Vector<ChatSocket>();//存放所有的客户端socket
     public MyServerSocket()
     {
         try
         {
             ServerSocket serverSocket=new ServerSocket(13345);//服务端开启对端口13345的监听
             while(true)
             {
               Socket socket=serverSocket.accept();//服务器端提供与客户端相对应的socket
               JOptionPane.showMessageDialog(null, "已经有客户端连入");
               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
               add(cs);
               cs.start();
             }
         } catch (IOException e)
         {
             // TODO 自动生成的 catch 块
             e.printStackTrace();
         }
     }
     public void add(ChatSocket csSocket)//服务器端添加每一个客户端socket
     {
         vector.add(csSocket);
     }
     public static void main(String[]args)
     {
         new MyServerSocket();
     }
 }

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

 package MyServer;

 import java.io.BufferedOutputStream;
 import java.io.BufferedReader;
 import java.io.BufferedWriter;
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.InputStreamReader;
 import java.io.OutputStream;
 import java.io.OutputStreamWriter;
 import java.io.UnsupportedEncodingException;
 import java.net.Socket;
 import java.nio.Buffer;
 import java.util.Vector;

 import javax.swing.text.AbstractDocument.BranchElement;

 public class ChatSocket extends Thread
 {
     Socket socket;
     Vector<ChatSocket>vector;
     public ChatSocket(Socket s,Vector<ChatSocket>vector)
     {
         this.socket=s;
         this.vector = vector;
     }
     public void out(String out)//服务器发送消息给客户端
     {
        try
     {
         BufferedWriter bfWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
         bfWriter.write(out+"\n");
         bfWriter.flush();//清空缓冲区，避免消息延迟显示
     } catch (UnsupportedEncodingException e)
     {
         // TODO 自动生成的 catch 块
         e.printStackTrace();
     } catch (IOException e)
     {
         // TODO 自动生成的 catch 块
         e.printStackTrace();
     }
     }
     @Override
     public void run()
     {
         try
         {
             BufferedReader bufferedReader=new BufferedReader(
                                                                      new InputStreamReader(
                                                                              socket.getInputStream()));
             String line = null;
             while((line=bufferedReader.readLine())!=null)//服务端接收客户端的消息
             {
                 sendMessage(this, line);//转发给其他客户端
                 System.out.println(line);
             }
             bufferedReader.close();
         } catch (IOException e)
         {
             // TODO 自动生成的 catch 块
             e.printStackTrace();
         }
     }
     public void sendMessage(ChatSocket cs,String out)
     {
         for(int i=0;i<vector.size();i++)
         {
             ChatSocket csChatSocket=vector.get(i);
             if(!cs.equals(csChatSocket))//将发送该消息的客户端除外
             {
                 csChatSocket.out(out);
             }
         }
     }

 }

最后的效果图

客户端可开启两个及以上的虚拟机进行客户端的聊天
