Android中Socket通信案例

以下这个案例是基于TCP/UDP协议的。

服务端实现代码

基于TCP的服务端协议
          // 声明一个ServerSocket对象
            ServerSocket serverSocket = null;
            try {
                serverSocket = new ServerSocket(4567);
                Socket socket = serverSocket.accept();
                InputStream inputStream = socket.getInputStream();

            } catch (Exception e) {
                // TODO: handle exception
            }

基于UDP的服务端协议
try {　　　　　　　　
                DatagramSocket socket = new DatagramSocket(4567);
                byte[] bytes = new byte[1024];
                DatagramPacket packet = new DatagramPacket(bytes, bytes.length);
                socket.receive(packet);

            } catch (Exception e) {
                // TODO: handle exception
            }

客户端实现代码

基于TCP协议的客户端
publicvoid run() {

// TODO Auto-generated method stub
            try {
                Socket socket = new Socket("192.168.1.110", 4567);
                OutputStream outputStream = socket.getOutputStream();
                InputStream inputStream = new FileInputStream("f:/abc.txt");
                byte[] bytes = new byte[2 * 1024];
                while (true) {
                    int temp = inputStream.read(bytes, 0, bytes.length);
                    if (temp == -1) {
                        break;

                    } else {
                        outputStream.write(bytes, 0, temp);
                    }
                }
                outputStream.flush();
            } catch (Exception e) {
                // TODO: handle exception
            } finally {
            }

        }

基于UDP协议的客户端
public void run() {
            // TODO Auto-generated method stub
            try {
                // 定义一个DatagramSocket对象，并设置端口号为4567
                DatagramSocket socket = new DatagramSocket(4567);
                InetAddress address = InetAddress.getByName("192.168.1.110");
                System.out.println(address);
                String str = "hello";
                byte[] data = str.getBytes();
                DatagramPacket packet = new DatagramPacket(data, 0,
                        data.length, address, 4567);
                socket.send(packet);
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }

        }
