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
view plaincopy to clipboardprint?
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 \r\n";
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());
}
}
}
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 \r\n";
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
view plaincopy to clipboardprint?
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\n");
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());
}
}
}
