用socket連接服務器的時候，需要在子線程進行網絡請求，請求完成之後可以通過Handler來處理主線程應該得到的通知（更新view）

private void StartRequestFromSocket(final int mycho) {
    new Thread() {
        public void run() {
            try {
                SendRequest(mycho);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }.start();
}

public void SendRequest(int mycho) {
    String sendString="sendString";
    try {
        socket = new Socket(IpAddress, Port);
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        // 由系統標準輸入設備構造BufferedReader對象
        PrintWriter write = new PrintWriter(socket.getOutputStream());
        // 由Socket對象得到輸出流，並構造PrintWriter對象
        BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        write.println(sendString);
        write.flush();
        getS = in.readLine();
        System.out.println("Server:" + getS);
        mHandler.sendEmptyMessage(mycho);
    } catch (UnknownHostException e1) {
        e1.printStackTrace();
    } catch (IOException e1) {
        e1.printStackTrace();
    } finally {
        try {
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
