Java 而客户端线程（套接字）中的循环只输入了两次（android）

我正在为Android中的服务器/客户端通信设置一个客户端线程。我可以很好地设置连接。但是当我尝试使用下面的代码循环时，程序只进入while循环两次。（我也试过了，虽然（正确），但什么也没发生…）

我需要线程等待客户端对象更新sendPicture/sendLinks等。。为true发送示例行pw.println（“PICTURE”）

在服务器端（PC），它工作得很好（创建1个用于通信的ServerSocket和其他用于文件传输的ServerSocket）

非常感谢您的帮助

已尝试：while（true）

实际输出在此停止：

I/--main活动：-------------绑定完成

I/ClientSocketThread:--------------为true---------------------------------------------

I/System.out：有下一行

______________________________行：允许

I/ClientSocketThread:--------------为真------------------------------------------

此方法在等待输入时可能会阻塞

可能是这样

public ClientSocketThread(String ip, int port, MainActivity.myClientSocketThreadHandler h, String message, Client c) {
        this.IP = ip;
        this.message = message;
        this.port = port;
        this.handler = h;
        this.client = c;
        this.clientName = c.getClientName();

    }


    public void run() {
        try {
            clientSocket = new Socket(this.IP, port);
            Scanner is = new Scanner(clientSocket.getInputStream());
            pw = new PrintWriter(clientSocket.getOutputStream(), true);
            String line = "";
            pw.println(message);
            while (!line.equals("OVER")) {

                Log.i("ClientSocketThread", "------------------In true---------------------------------------------");

                if (is.hasNextLine()) {
                    System.out.println("Has next line");
                    line = is.nextLine();
                }else{
                    line = "";
                }

                System.out.println("______________________________Line: " + line);

                    Message msg = handler.obtainMessage();
