Scoket的多线程使用之手机客户端的…

手机客户端的创建也是包括两个类，一个是主要的Activity类，另一个是负责和远程服务器连接和通信的子线程类。

一、主要的Activity类

public class MultiThreadClient extends Activity {

EditText input;

TextView show;

Button send;

Handler handler;

ClientThread clientThread;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

input = (EditText)findViewById(R.id.input);

send = (Button)findViewById(R.id.send);

show = (TextView)findViewById(R.id.show);

handler = new Handler(){

@Override

public void handleMessage(Message msg) {

if(msg.what == 0x123){

show.append("\n" + msg.obj.toString());

}

}

};

clientThread = new ClientThread(handler);

new Thread(clientThread).start();

send.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

try{

Message msg = new Message();

msg.what = 0x345;

msg.obj = input.getText().toString();

clientThread.revHandler.handleMessage(msg);

input.setText("");

}catch (Exception e) {

e.printStackTrace();

}

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if itis present.

getMenuInflater().inflate(R.menu.mmulti_thread_client,menu);

return true;

}

}

二、负责和远程服务器连接和通信的子线程类

public class ClientThread implements Runnable{

private Socket s;

private Handler handler;

public Handler revHandler;

BufferedReader br = null;

OutputStream os = null;

public ClientThread(Handler handler) {

this.handler = handler;

}

@SuppressLint("HandlerLeak")

@Override

public void run() {

try {

s = new Socket("10.10.31.2", 12321);

br = new BufferedReader(newInputStreamReader(s.getInputStream()));

os = s.getOutputStream();

new Thread(){

public void run(){

String content = null;

try {

while ((content = br.readLine()) != null) {

Message msg = new Message();

msg.what = 0x123;

msg.obj = content;

handler.sendMessage(msg);

}

} catch (Exception e) {

// TODO: handle exception

}

}

}.start();

Looper.prepare();

revHandler = new Handler(){

public void handleMessage(Message msg){

if(msg.what == 0x345){

try{

os.write((msg.obj.toString() +"\r\n").getBytes("utf-8"));

}catch (Exception e) {

e.printStackTrace();

}

}

}

};

Looper.loop();

}

catch (SocketTimeoutException e1) {

System.out.println("网络连接超时！");

}catch (Exception e) {

e.printStackTrace();

}

}

}
