Question

我使用this Tutorial建立客户端服务器连接。我面临的问题是它不会停止，Log cat继续显示客户端在无限循环中发送数据。此外，服务器在无限循环中接收此数据

这是我的code

任何建议/更改都将受到赞赏，我被困在这个问题，昨天coud'nt罚款一个良好的工作解决方案谷歌。

感谢

客户端代码

    public class ClientThread implements Runnable {


    public void run() {
        try {

            InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
            Log.d("ClientActivity", "C: Connecting...");
            socket = new Socket(serverAddr, 8080);
            connected = true;
            while (connected) {
                try {
                    Log.d("ClientActivity", "C: Sending command.");
                    PrintWriter out = new PrintWriter(new BufferedWriter(new 
                     OutputStreamWriter(socket
                                .getOutputStream())), true);
                        // where you issue the commands

                        out.println(serverIpAddress);
                        //connected = false;
                        //socket.close();
                        Log.d("ClientActivity", "C: Sent.");

                } catch (Exception e) {
                    Log.e("ClientActivity", "S: Error", e);
                }


            }
            socket.close();
            Log.d("ClientActivity", "C: Closed.");
        } catch (Exception e) {
            Log.e("ClientActivity", "C: Error", e);
            connected = false;

取消注释行//connected = false;应该可以正常工作。

写入流操作后，你应该退出而不是写回同样的东西。

Android实现Runnable没有终止
