android实现PC到手机的SOCKET通信

以手机为服务器端，PC为客户端

客户端：

 

public void actionPerformed(ActionEvent e) {
    // TODO Auto-generated method stub
    // 创建Socket
    Socket socket = null;
    DataOutputStream out = null;
    BufferedReader br = null;
    inputText.setEditable(false);
    try {
        //创建一个Socket对象，指定服务器端的IP地址和端口号
        socket = new Socket("192.168.137.167", 5000);
        // 客户端给服务器发送消息
        out = new DataOutputStream(socket.getOutputStream());
        String inputCommand = inputText.getText();
        System.out.println(inputCommand);
        if (inputCommand != null) {
            out.writeUTF(inputCommand);
        }
        out.flush();
        // 接收来自服务器的消息

        br = new BufferedReader(new InputStreamReader(
                socket.getInputStream()));

        String msg = br.readLine();
        System.out.println("客户端"+msg);
        showText.append(msg+'\n');
    /*  while ((msg = br.readLine()) != null) {

            System.out.println("客户端"+msg);
        } */

    //  socket.close();
    } catch (UnknownHostException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e2) {
        // TODO Auto-generated catch block
        e2.printStackTrace();
    } finally {
        inputText.setEditable(true);
        try {
            if (out != null) {
                out.close();
            }
            if (br != null) {
                br.close();
            }
            if (socket != null) {
                socket.close();
            }
        } catch (IOException e3) {
            // TODO Auto-generated catch block
            e3.printStackTrace();
        }
    }

}
