在Android中连接2个仿真器实例

概述我想在2Emulator中创建一个Server和一个Client来写入和读取数据.我为Server编写代码：publicclassServerActivityextendsActivity{/**Calledwhentheactivityisfirstcreated.*/privateServerSocketserverSocket=null;privateTextViewtv;publicstat

我想在2 Emulator中创建一个Server和一个ClIEnt来写入和读取数据.
我为Server编写代码：

public class ServerActivity extends Activity {    /** Called when the activity is first created. */ private ServerSocket serverSocket = null; private TextVIEw tv; public static final int SERVERPORT = 4444;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.main);        tv= (TextVIEw) findVIEwByID(R.ID.myTextVIEw);        try {   Connect();  } catch (IOException e) {   // Todo auto-generated catch block   tv.setText("Not connected");   e.printstacktrace();  }    }    public voID Connect() throws IOException    {     serverSocket = new ServerSocket();     serverSocket.bind(new InetSocketAddress("10.0.2.15", 4444));     while(true)     {      Socket socket = serverSocket.accept();      tv.setText("Connected...");     }    }

和客户代码

public class ClIEntActivity extends Activity {    /** Called when the activity is first created. */ private button bt; private TextVIEw tv;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.main);        bt = (button) findVIEwByID(R.ID.mybutton);        tv = (TextVIEw) findVIEwByID(R.ID.myTextVIEw);        bt.setonClickListener(new OnClickListener() {   public voID onClick(VIEw v) {    // Todo auto-generated method stub    try {     Socket socket  = new Socket("10.0.2.2", 4445);    } catch (UnkNownHostException e) {     // Todo auto-generated catch block     tv.setText("Error1");     e.printstacktrace();    } catch (IOException e) {     // Todo auto-generated catch block     tv.setText("Error2");     e.printstacktrace();    }   }  });    }}

我设置了一个重定向：

telnet localhost 5554redir add tcp:4445:4444

但它没有连接….请帮助我.我很感激.

解决方法:

过了一会儿,我成功了.我没有在服务器或客户端对10.0.2.15做任何引用.我以不同方式打开服务器套接字,并在单独的线程中处理了通信.我在模拟器5554上运行服务器,在5556上运行客户端.

我的服务器代码,听6000

public class SocketServer extends Activity {   ServerSocket ss = null;   String mClIEntMsg = "";   Thread myCommsThread = null;   protected static final int MSG_ID = 0x1337;   public static final int SERVERPORT = 6000;   @OverrIDe   public voID onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentVIEw(R.layout.main);      TextVIEw tv = (TextVIEw) findVIEwByID(R.ID.TextVIEw01);      tv.setText("nothing from clIEnt yet");      this.myCommsThread = new Thread(new CommsThread());      this.myCommsThread.start();   }   @OverrIDe   protected voID onStop() {      super.onStop();      try {         // make sure you close the socket upon exiting         ss.close();      } catch (IOException e) {         e.printstacktrace();      }   }   Handler myUpdateHandler = new Handler() {      public voID handleMessage(Message msg) {         switch (msg.what) {         case MSG_ID:            TextVIEw tv = (TextVIEw) findVIEwByID(R.ID.TextVIEw01);            tv.setText(mClIEntMsg);            break;         default:            break;         }         super.handleMessage(msg);      }   };   class CommsThread implements Runnable {      public voID run() {         Socket s = null;         try {            ss = new ServerSocket(SERVERPORT );         } catch (IOException e) {            e.printstacktrace();         }         while (!Thread.currentThread().isInterrupted()) {            Message m = new Message();            m.what = MSG_ID;            try {               if (s == null)                  s = ss.accept();               BufferedReader input = new BufferedReader(                     new inputStreamReader(s.getinputStream()));               String st = null;               st = input.readline();               mClIEntMsg = st;               myUpdateHandler.sendMessage(m);            } catch (IOException e) {               e.printstacktrace();            }         }      }   }}

我重定向了类似于你的端口

telnet localhost 5554redir add tcp:5000:6000

我的客户端代码在端口5000上建立连接：

public class SocketClIEnt extends Activity {   private button bt;   private TextVIEw tv;   private Socket socket;   private String serverIpAddress = "10.0.2.2";   // AND THAT'S MY DEV'T MACHINE WHERE PACKETS TO   // PORT 5000 GET REDIRECTED TO THE SERVER EMulATOR'S   // PORT 6000   private static final int REDIRECTED_SERVERPORT = 5000;   @OverrIDe   public voID onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentVIEw(R.layout.main);      bt = (button) findVIEwByID(R.ID.mybutton);      tv = (TextVIEw) findVIEwByID(R.ID.myTextVIEw);      try {         InetAddress serverAddr = InetAddress.getByname(serverIpAddress);         socket = new Socket(serverAddr, REDIRECTED_SERVERPORT);      } catch (UnkNownHostException e1) {         e1.printstacktrace();      } catch (IOException e1) {         e1.printstacktrace();      }      bt.setonClickListener(new OnClickListener() {         public voID onClick(VIEw v) {            try {               EditText et = (EditText) findVIEwByID(R.ID.EditText01);               String str = et.getText().toString();               PrintWriter out = new PrintWriter(new BuffereDWriter(                     new OutputStreamWriter(socket.getoutputStream())),                     true);               out.println(str);               Log.d("ClIEnt", "ClIEnt sent message");            } catch (UnkNownHostException e) {               tv.setText("Error1");               e.printstacktrace();            } catch (IOException e) {               tv.setText("Error2");               e.printstacktrace();            } catch (Exception e) {               tv.setText("Error3");               e.printstacktrace();            }         }      });   }}

服务器有一个TextVIEw来接收消息,客户端有一个EditText来组成消息,一个按钮来发送它.
