這篇文章主要為大家詳細(xì)介紹了安卓手機(jī)socket通信，服務(wù)器和客戶端的代碼，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了安卓手機(jī)socket通信代碼，供大家參考，具體內(nèi)容如下

1、socket通信首先要定義好服務(wù)端的ip地址和端口號(hào)；

(1).首先看服務(wù)端的代碼：

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?yàn)槭鞘謾C(jī)做服務(wù)端，所以在開始操作的時(shí)候客戶端是不知道ip和端口號(hào)的，但在服務(wù)端運(yùn)行后就可以看到（親：你可以自己測試）

2、客戶端的代碼

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("建立連接").start();
 send.setOnClickListener(new OnClickListener() {

  @Override
  public void onClick(View v) {
  geted1 = ed1.getText().toString();
  txt1.append("client:" + geted1 + "\n");
  // 啟動(dòng)線程 向服務(wù)器發(fā)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() {
  // 定義消息
  Message msg = new Message();
  msg.what = 0x11;
  Bundle bundle = new Bundle();
  bundle.clear();
  try {
  // 連接服務(wù)器 并設(shè)置連接超時(shí)為5秒
  socket = new Socket();
  socket.connect(new InetSocketAddress("172.20.226.11", 30000), 1000);
  // 獲取輸入輸出流
  OutputStream ou = socket.getOutputStream();
  BufferedReader bff = new BufferedReader(new InputStreamReader(socket.getInputStream()));
  // 讀取發(fā)來服務(wù)器信息
  String line = null;
  buffer = "";
  while ((line = bff.readLine()) != null) {
   buffer = line + buffer;
  }

  // 向服務(wù)器發(fā)送信息
  ou.write(txt1.getBytes("gbk"));
  ou.flush();
  bundle.putString("msg", buffer.toString());
  msg.setData(bundle);
  // 發(fā)送消息 修改UI線程中的組件
  myHandler.sendMessage(msg);
  // 關(guān)閉各種輸入輸出流
  bff.close();
  ou.close();
  socket.close();
  } catch (SocketTimeoutException aa) {
  // 連接超時(shí) 在UI界面顯示消息
  bundle.putString("msg", "服務(wù)器連接失??！請(qǐng)檢查網(wǎng)絡(luò)是否打開");
  msg.setData(bundle);
  // 發(fā)送消息 修改UI線程中的組件
  myHandler.sendMessage(msg);
  } catch (IOException e) {
  e.printStackTrace();
  }
 }
 }

}

3、最后別忘記加網(wǎng)絡(luò)權(quán)限

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