Question

我需要你的帮助。我想这样做：我的socket TCP中有Timer和IntentService任务。这是我的代码：

 protected void onHandleIntent(Intent intent)
{
    String add = intent.getStringExtra("address");
    Log.d("add",add);
    int porta = Integer.parseInt(intent.getStringExtra("port"));
    InetAddress serverAddr = null;
    try
    {
        serverAddr = InetAddress.getByName(add);
        socket = new Socket(serverAddr, porta);
        socketHandler.setSocket(socket);


        final PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
        out.print("go");
        out.flush();

        final byte[] bytes = new byte[1000];
        int counter;
        String reader;
        final InputStream data = socket.getInputStream();

        int numRead = 0;

        if ((numRead = data.read(bytes)) >= 0)
        {
            reader=new String(bytes, 0, numRead);
        }

        if (reader.equals("Let's go"))
        {
         //socket connected
        }

        pingTimer = new Timer();
        pingTimer.scheduleAtFixedRate(new TimerTask() {
            String reader; int r;

            public void run()
            {


               out.write("ping");
               out.flush();

               if(out.checkError())
               {
                  onDestroy();
               }
            }

        }, 0, 20000);

        InputStream readeIn = socket.getInputStream();
        char [] buffer = new char[1024];

        BufferedReader in = new BufferedReader(new InputStreamReader(readeIn));

        while((counter = in.read(buffer)) != -1)
        {

         //read here
        }

    catch (UnknownHostException e)
    {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
        onDestroy();
    }
}

public void onDestroy()
{
 //destroy socket
}

它运作良好。现在我想这样做：我想把一个计时器放到套接字上。所以，插座上升了3分钟;如果它收到了什么，重新放3分钟听，但如果在这3分钟套接字没有收到任何东西，我想关闭套接字。我该怎么做？谢谢你的回答。

您需要使用Socket.setSoTimeout()的参数调用3*60*1000，该参数对应于三分钟（60分钟给出秒，1000分钟给出毫秒），并相应地处理结果SocketTimeoutException

如何将计时器放入TCP套接字？
