简单的Socket通信实例：实现Android客户端与PC服务端的简单通信

今天来写一个使用Socket通信的小小实例

实现效果：快看动图

 

效果说明：当点击发送时，是先将文本内容发送到本地服务器，之后再从服务器中获取显示到TextView中的

PC服务端实现：

package com.lollo.server;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.Iterator;
/*
 * 服务端的任务：
 * 1：负责接收每一个客户端传来的数据
 * 2: 将读取到的客户端的数据发送给 其他每一个客户端(包括自己)
 */
public class SimpleServerList {
	public static ArrayList<Socket>socketList=new ArrayList();
	public static void main(String[]args) throws IOException{
		final ServerSocket server=new ServerSocket(8090);
		System.out.println("服务器已建立："+server);
		//时刻监听
		new Thread(){
			public void run(){
				while(true){
					try{
						Socket socket=server.accept();
						socketList.add(socket);
						ServerThread serverThread=new ServerThread(socket);
						serverThread.start();
					}catch (IOException e){
						//System.out.println("服务端移除socket");
						//socketList.remove(socket);
					}
				}
			}
		}.start();
}
private static class ServerThread extends Thread{
	Socket socket;
	//负责读取客户端的数据
	DataInputStream input;
	DataOutputStream output;
	public ServerThread(Socket socket) throws IOException{
		this.socket=socket;
		input=new DataInputStream(socket.getInputStream());
	}
	//读取客户端数据并发送给每一个其他客户端
	public void run(){
		String content=null;
		//if((content=readFromClient())!=null){
		while((content=readFromClient())!=null){
			//遍历所有客户端的socket
			for(Iterator<Socket> it=SimpleServerList.socketList.iterator();it.hasNext();){
				try{
					Socket socket=it.next();
					output=new DataOutputStream(socket.getOutputStream());
					//发送给其他客户端
					output.writeUTF(content+"\n");
				}catch(IOException e){
				    
				}
			}
		}
	}
	private String readFromClient(){
		String readStr=null;
		try {
			readStr=input.readUTF();
		} catch (IOException e) {
			System.out.println("移除socket：");
			SimpleServerList.socketList.remove(socket);
		}
		return readStr;
	}
 }
}

 

Android客户端的实现：

package com.lollo.server;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.Iterator;
/*
 * 服务端的任务：
 * 1：负责接收每一个客户端传来的数据
 * 2: 将读取到的客户端的数据发送给 其他每一个客户端(包括自己)
 */
public class SimpleServerList {
	public static ArrayList<Socket>socketList=new ArrayList();
	public static void main(String[]args) throws IOException{
		final ServerSocket server=new ServerSocket(8090);
		System.out.println("服务器已建立："+server);
		//时刻监听
		new Thread(){
			public void run(){
				while(true){
					try{
						Socket socket=server.accept();
						socketList.add(socket);
						ServerThread serverThread=new ServerThread(socket);
						serverThread.start();
					}catch (IOException e){
						//System.out.println("服务端移除socket");
						//socketList.remove(socket);
					}
				}
			}
		}.start();
}
private static class ServerThread extends Thread{
	Socket socket;
	//负责读取客户端的数据
	DataInputStream input;
	DataOutputStream output;
	public ServerThread(Socket socket) throws IOException{
		this.socket=socket;
		input=new DataInputStream(socket.getInputStream());
	}
	//读取客户端数据并发送给每一个其他客户端
	public void run(){
		String content=null;
		//if((content=readFromClient())!=null){
		while((content=readFromClient())!=null){
			//遍历所有客户端的socket
			for(Iterator<Socket> it=SimpleServerList.socketList.iterator();it.hasNext();){
				try{
					Socket socket=it.next();
					output=new DataOutputStream(socket.getOutputStream());
					//发送给其他客户端
					output.writeUTF(content+"\n");
				}catch(IOException e){
				    System.out.println("Iterator移除socket：");
				    it.remove();
				    System.out.println(SimpleServerList.socketList);
					//SimpleServerList.socketList.remove(socket);
				}
			}
		}
	}
	private String readFromClient(){
		String readStr=null;
		try {
			readStr=input.readUTF();
		} catch (IOException e) {
			System.out.println("移除socket：");
			SimpleServerList.socketList.remove(socket);
		}
		return readStr;
	}
 }
}
