java - 异步套接字客户端

Question

我正在开发一个基于线程的异步套接字客户端。当程序调用readLine()时，它会无限期地阻塞并且永远不会返回。

public class ADNClient {

  Socket socket = null;
  DataOutputStream dataOutputStream = null;
  DataInputStream dataInputStream = null;

  Thread listener = new Thread(new Runnable() {
    @Override
    public void run() {
      String line;
      try {
        // Stop here and doesn't progress
        while ((line = dataInputStream.readLine()) != null) {
          //DO something
        }
      } 
      catch (IOException e) {}
    });

    public ADNClient() {
    try {
      socket = new Socket("192.168.1.5", 5000);
      dataOutputStream = new DataOutputStream(socket.getOutputStream());
      dataInputStream = new DataInputStream(socket.getInputStream());
      listener.start();
      //sender.start();
    } catch (Exception e) {
      Log.e("ADN", e.getMessage());
    }
  }

  public void close() {
    listener.stop();
    try {
      socket.close();
    } catch (IOException e) {
      Log.e("ADN", e.getMessage());
    }
  }
}

好的...我是输入/输出流的菜鸟...我没有发送换行符，接收信息的正确方法是使用

readUTF()

代替

readLine()
