本文实例为大家分享了安卓手机socket通信代码，供大家参考，具体内容如下

1、socket通信首先要定义好服务端的ip地址和端口号；

(1).首先看服务端的代码：

package com.example.androidsockettest;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;import android.net.wifi.WifiInfo;import android.net.wifi.WifiManager;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.app.Activity;import android.content.Context;import android.view.Menu;import android.widget.TextView;public class MainActivity extends Activity { public static ServerSocket serverSocket = null; public static TextView mTextView, textView1; private String IP = ""; String buffer = ""; public static Handler mHandler = new Handler() { @Override public void handleMessage(android.os.Message msg) { if (msg.what==0x11) { Bundle bundle = msg.getData(); mTextView.append("client"+bundle.getString("msg")+"\n"); } }; }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTextView = (TextView) findViewById(R.id.textsss); textView1 = (TextView) findViewById(R.id.textView1); IP = getlocalip(); textView1.setText("IP addresss:"+IP); new Thread() { public void run() { Bundle bundle = new Bundle(); bundle.clear(); OutputStream output; String str = "通信成功"; try { serverSocket = new ServerSocket(30000); while (true) { Message msg = new Message(); msg.what = 0x11; try { Socket socket = serverSocket.accept(); output = socket.getOutputStream(); output.write(str.getBytes("UTF-8")); output.flush(); socket.shutdownOutput(); //mHandler.sendEmptyMessage(0); BufferedReader bff = new BufferedReader(new InputStreamReader(socket.getInputStream())); String line = null; buffer = ""; while ((line = bff.readLine())!=null) { buffer = line + buffer; } bundle.putString("msg", buffer.toString()); msg.setData(bundle); mHandler.sendMessage(msg); bff.close(); output.close(); socket.close(); } catch (IOException e) { e.printStackTrace(); } } } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } }; }.start(); } private String getlocalip(){ WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE); WifiInfo wifiInfo = wifiManager.getConnectionInfo(); int ipAddress = wifiInfo.getIpAddress(); // Log.d(Tag, "int ip "+ipAddress); if(ipAddress==0)return null; return ((ipAddress & 0xff)+"."+(ipAddress>>8 & 0xff)+"." +(ipAddress>>16 & 0xff)+"."+(ipAddress>>24 & 0xff)); } }

(2).因为是手机做服务端，所以在开始操作的时候客户端是不知道ip和端口号的，但在服务端运行后就可以看到（亲：你可以自己测试）

2、客户端的代码

package com.example.andoroidclient;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStream;import java.net.InetSocketAddress;import java.net.Socket;import java.net.SocketTimeoutException;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.app.Activity;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;public class MainActivity extends Activity { Socket socket = null; String buffer = ""; TextView txt1; Button send; EditText ed1; String geted1; public Handler myHandler = new Handler() { @Override public void handleMessage(Message msg) { if (msg.what == 0x11) { Bundle bundle = msg.getData(); txt1.append("server:" + bundle.getString("msg") + "\n"); } } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); txt1 = (TextView) findViewById(R.id.txt1); send = (Button) findViewById(R.id.send); ed1 = (EditText) findViewById(R.id.ed1); new MyThread("建立连接").start(); send.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { geted1 = ed1.getText().toString(); txt1.append("client:" + geted1 + "\n"); // 启动线程 向服务器发送和接收信息 new MyThread(geted1).start(); } }); } class MyThread extends Thread { public String txt1; public MyThread(String str) { txt1 = str; } @Override public void run() { // 定义消息 Message msg = new Message(); msg.what = 0x11; Bundle bundle = new Bundle(); bundle.clear(); try { // 连接服务器 并设置连接超时为5秒 socket = new Socket(); socket.connect(new InetSocketAddress("172.20.226.11", 30000), 1000); // 获取输入输出流 OutputStream ou = socket.getOutputStream(); BufferedReader bff = new BufferedReader(new InputStreamReader(socket.getInputStream())); // 读取发来服务器信息 String line = null; buffer = ""; while ((line = bff.readLine()) != null) { buffer = line + buffer; } // 向服务器发送信息 ou.write(txt1.getBytes("gbk")); ou.flush(); bundle.putString("msg", buffer.toString()); msg.setData(bundle); // 发送消息 修改UI线程中的组件 myHandler.sendMessage(msg); // 关闭各种输入输出流 bff.close(); ou.close(); socket.close(); } catch (SocketTimeoutException aa) { // 连接超时 在UI界面显示消息 bundle.putString("msg", "服务器连接失败！请检查网络是否打开"); msg.setData(bundle); // 发送消息 修改UI线程中的组件 myHandler.sendMessage(msg); } catch (IOException e) { e.printStackTrace(); } } }}

3、最后别忘记加网络权限

<uses-permission android:name="android.permission.INTERNET" />
