Android下使用Socket连接网络电脑

冷风

既然是使用SOCKET连接网络上的电脑，就分为两部分

其一,Android上面的Client

其二,PC上的Server

Android上面的实现代码如下

package Hello.MySocket;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MySocket extends Activity {
private final String DEBUG_TAG="lengfeng";
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Log.v("lengfeng","Android Start Connect");

    Socket socket=null;
    String mesg="my name is log ";
    try {
     socket=new Socket("10.0.2.2",54321);
     //向服务器发送信息
     PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
     out.println(mesg);

     //接受服务器的信息
     BufferedReader br=new BufferedReader(new InputStreamReader(socket.getInputStream()));
     String mstr=br.readLine();
     if(mstr!=null)
     {
      Log.e(DEBUG_TAG,mesg);
     }else
     {
      Log.e(DEBUG_TAG,"数据错误");
     }
     out.close();
     br.close();
     socket.close();
    } catch (UnknownHostException e) {
     e.printStackTrace();
    } catch (IOException e) {
     e.printStackTrace();
    }catch(Exception e)
    {
     Log.e(DEBUG_TAG,e.toString());
    }
    }
}

PC上面的Server 创建一个java的项目

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

public class MyJavaServer {
/**
* @param args
*/

public static void main(String[] args) {
  // TODO Auto-generated method stub
  System.out.print("MyJavaServer Start Runing ");

  try {
   ServerSocket serverSocket=new ServerSocket(54321);
   while(true)
   {
    System.out.println("接收用户连接：");
    //接受客户端请求
    Socket client=serverSocket.accept();
    System.out.println("accept:");
    try
    {
     //接受客户端信息
     BufferedReader in=new BufferedReader(new InputStreamReader(client.getInputStream()));
     String str=in.readLine();
     System.out.println("read:"+str);
     //向服务器发送消息
     PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(client.getOutputStream())),true);
     out.println("Server Message："+str);
     in.close();
     out.close();
    }catch(Exception ex)
    {
     System.out.println(ex.getMessage());
     ex.printStackTrace();
    }
    finally
    {
     client.close();
     System.out.println("close");
    }
   }
  } catch (IOException e) {
   System.out.println(e.getMessage());
  }
}

}
