在Android中,可以使用Java中的Socket类来实现双向通信。以下是使用Socket类进行双向通信的基本步骤:
ServerSocket serverSocket = new ServerSocket(port);
Socket clientSocket = serverSocket.accept();
Socket socket = new Socket(serverIP, port);
InputStream inputStream = clientSocket.getInputStream();
OutputStream outputStream = clientSocket.getOutputStream();
InputStream inputStream = socket.getInputStream();
OutputStream outputStream = socket.getOutputStream();
// 服务器端
byte[] buffer = new byte[1024];
int bytesRead = inputStream.read(buffer);
String message = new String(buffer, 0, bytesRead);
outputStream.write(message.getBytes());
// 客户端
String message = "Hello, server!";
outputStream.write(message.getBytes());
byte[] buffer = new byte[1024];
int bytesRead = inputStream.read(buffer);
String response = new String(buffer, 0, bytesRead);
// 服务器端
clientSocket.close();
serverSocket.close();
// 客户端
socket.close();
请注意,这只是一个基本示例,并且可能需要进行错误处理和线程管理等更复杂的操作。
