socketServer類

package com.socket.server; import java.io.*;import java.net.*; import android.content.Context;import android.content.Intent; public class SocketServer { ServerSocket sever;Context context; public SocketServer(Context context, int port) {try {//執行個體化ServerSocket傳入連接埠號碼sever = new ServerSocket(port);this.context = context;} catch (IOException e) {e.printStackTrace();}} public void ControlActionAnswerMsg(String str) {final Intent intent = new Intent();intent.setAction("SOCKET_ACTION");intent.putExtra("message", str);context.sendBroadcast(intent);} public void beginListen() {//將socket監聽放入線程中，防止影響主線程操作new Thread() {public void run() {//因為是不斷監聽的過程，所以採用死迴圈while (true) {try {//這裡是做監聽操作final Socket socket = sever.accept(); BufferedReader in;try {//監聽到訊息後這裡讀取流資訊in = new BufferedReader(new InputStreamReader(socket.getInputStream(), "UTF-8"));//將流資訊放入PrintWriter中，然後讀出來即可PrintWriter out = new PrintWriter(socket.getOutputStream());while (!socket.isClosed()) {String str;//讀出字串str = in.readLine();out.println("Hello!world!! " + str);out.flush();if (str == null || str.equals("end"))break;System.out.println(str);ControlActionAnswerMsg(str);}socket.close();} catch (IOException e) {e.printStackTrace();}} catch (IOException e) {e.printStackTrace();}} }}.start();}}

ClientSocket類

package com.socket.pc;import java.io.*;import java.net.*;public class ClientSocket { static Socket client; public ClientSocket(String site, int port) {  try {   //執行個體化socket傳入ip和連接埠號碼，兩邊連接埠號碼要統一   client = new Socket(site, port);   System.out.println("Client is created! site:" + site + " port:"     + port);  } catch (UnknownHostException e) {   e.printStackTrace();  } catch (IOException e) {   e.printStackTrace();  } } public String sendMsg(String msg) {  try {   // BufferedReader in = new BufferedReader(new InputStreamReader(   // client.getInputStream()));   //將字串轉成輸出資料流然後發送出去   PrintWriter out = new PrintWriter(client.getOutputStream());   out.println(msg);   out.flush();   // return in.readLine();  } catch (IOException e) {   e.printStackTrace();  }  return ""; } public void closeSocket() {  try {   client.close();  } catch (IOException e) {   e.printStackTrace();  } }}
