Android进阶篇Socket通信

Socket通信作为一种重要的数据交互方式，在Android开发过程也十分重要。

//TCP Socket服务端

            ServerSocket serverSocket = null;
            
            try {
                //4567 ServerSocket端口号
                serverSocket = new ServerSocket(4567);
                //服务端接受客户端的Socket请求
                Socket socket = serverSocket.accept();
                //获取输入流
                InputStream inputStream = socket.getInputStream();
                byte buffer[] = new byte[4*1024];
                int temp = 0;
                //将InputStream数据读入到Buffer中
                while((temp = inputStream.read(buffer)) != -1){
                    
                }
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }

客户端：

            try {
                Socket socket = new Socket("192.168.0.104", 4567);
                InputStream inputStream = new FileInputStream("f://file/word.txt");
                OutputStream outputStream = socket.getOutputStream();
                byte buffer[] = new byte[4*1024];
                int temp = 0;
                while((temp = inputStream.read(buffer)) != -1){
                    outputStream.write(buffer, 0, temp);
                }
            } catch (UnknownHostException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

UDP Socket服务端：

            try {
                DatagramSocket datagramSocket = new DatagramSocket(4567);
                byte data[] = new byte[4*1024];
                DatagramPacket datagramPacket = new DatagramPacket(data, data.length);
                datagramSocket.receive(datagramPacket);
            } catch (Exception e) {
                // TODO: handle exception
            }

客户端：

            try {
                DatagramSocket socket = new DatagramSocket(4567);
                InetAddress inetAddress = InetAddress.getByName("192.168.0.104");
                String helloWorld = "helloworld";
                byte[]  data = helloWorld.getBytes();
                DatagramPacket datagramPacket = new DatagramPacket(data, data.length, inetAddress,4567);
                socket.send(datagramPacket);
             } catch (Exception e) {
                // TODO: handle exception
            }
