Android socket编程 以非阻塞I/O服务器及Service为例

核心提示：private String message="";public void onCreate() {super.onCreate();ConnectToServer();StartServerListener();}public void onDestroy() {super.onDestroy()

private String message="";

public void onCreate() {

super.onCreate();

ConnectToServer();

StartServerListener();

}

public void onDestroy() {

super.onDestroy();

DisConnectToServer();

}

public void onStart(Intent intent, int startId) {

super.onStart(intent, startId);

}

/*

* IBinder方法 , LocalBinder 类,mBinder接口这三项用于

* Activity进行Service的绑定，点击发送消息按钮之后触发绑定

* 并通过Intent将Activity中的EditText的值

* 传送到Service中向服务器发送

*

* */

public IBinder onBind(Intent intent) {

message = intent.getStringExtra("chatmessage");

if(message.length()>0)

{

SendMessageToServer(message);

}

return mBinder;

}

public class LocalBinder extends Binder {

ReceiveMessage getService() {

}

}

private final IBinder mBinder = new LocalBinder();

//用于链接服务器端

public void ConnectToServer()

{

try {

client = SocketChannel.open();

client.connect(isa);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

//断开与服务器端的链接

public void DisConnectToServer()

{

try {

client.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

//启动服务器端的监听线程，从Server端接收消息

public void StartServerListener()
