Java多线程TCP套接字-从客户端接收消息，直到它们断开连接

我有下面的代码来接受来自Java服务器的多个客户端

private class SocketServerThread extends Thread {
        int count = 0;
        String error_message = null;
        @Override
        public void run() {
            try{
                serverSocket = new ServerSocket(theSocketServerPORT);
                while (true){
                    final Socket socket = serverSocket.accept();
                    count++;
                    runOnUiThread(new Runnable(){
                        @Override
                        public void run() {
                            Toast.makeText(getApplicationContext(),"New Client with IP: " + socket.getInetAddress() + " and PORT: " + socket.getPort(),Toast.LENGTH_LONG).show();
                        }
                    });
                    SocketServerListenToMessage socketServerListenToMessage = new SocketServerListenToMessage(socket); 
                    socketServerListenToMessage.run();// Start to Receive now
                }
            }catch (IOException e){
                Log.e("IO ERROR",e.toString());
                error_message = "IO ERROR";
            }catch (Exception e){

                Log.e("EX ERROR",e.toString());
                error_message = "EX ERROR";
            }
            if(error_message!=null){
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getApplicationContext(),error_message,Toast.LENGTH_LONG).show();
                    }
                });
            }
        }
    }

连接客户端后，我调用

SocketServerListenToMessage

开始监听客户端消息

下面的代码用于

SocketServerListentMessage

private class SocketServerListenToMessage extends Thread{
        Socket theClientSocket;
        SocketServerListenToMessage(Socket clientSocketListener){
            theClientSocket = clientSocketListener;
            Log.w("SERVER STATUS","Starting to Listen to Clients...");
        }
        @Override
        public void run(){
            try{
                InputStream is = theClientSocket.getInputStream();
                while(true){
                    byte[] lenBytes = new byte[4];
                    is.read(lenBytes, 0, 4);
                    int len = (((lenBytes[3] & 0xff) << 24) | ((lenBytes[2] & 0xff) << 16) |
                           ((lenBytes[1] & 0xff) << 8) | (lenBytes[0] & 0xff));
                    byte[] receivedBytes = new byte[len];
                    is.read(receivedBytes, 0, len);
                    final String received = new String(receivedBytes, 0, len);

                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(getApplicationContext(),"Client Says: " + received, Toast.LENGTH_LONG).show();
                            Log.w("Client Says", received);
                        }
                    });
                }
            }catch (IOException e){
                Log.e("IO ERR FROM LISTEN MSG", e.toString());
            }
            catch (Exception e){
                Log.e("EX ERR FROM LISTEN MSG", e.toString());
            }
        }
    }

我认为问题出在

SocketServerListentMessage

中的

while循环中。我试图删除
while循环
，服务器能够从所有客户端接收消息，但每个客户端只有一条消息。我希望服务器侦听客户端的消息，直到它们断开连接。我该怎么做呢？
我只是让它工作。多亏了这个

如果我没有弄错的话，从中可以看出，我使用的是单线程。因此，我必须从我的
SocketServerThread
中进行更改

SocketServerListenToMessage socketServerListenToMessage = new SocketServerListenToMessage(socket); 
                    socketServerListenToMessage.run();// Start to Receive now

到

并将类
SocketServerListentMessage
更改为

private class SocketServerListenToMessage implements Runnable {
        protected Socket clientSocket = null;

        public SocketServerListenToMessage(Socket clientSocket) {
            this.clientSocket = clientSocket;
        }

        @Override
        public void run() {
            try {
                while (true){
                    InputStream is = clientSocket.getInputStream();
                    byte[] lenBytes = new byte[4];
                    is.read(lenBytes, 0, 4);
                    int len = (((lenBytes[3] & 0xff) << 24) | ((lenBytes[2] & 0xff) << 16) |
                            ((lenBytes[1] & 0xff) << 8) | (lenBytes[0] & 0xff));
                    byte[] receivedBytes = new byte[len];
                    is.read(receivedBytes, 0, len);
                    final String received = new String(receivedBytes, 0, len);

                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(getApplicationContext(), "Client Says: " + received, Toast.LENGTH_LONG).show();
                            Log.w("Client Says", received);

                        }
                    });
                }

            } catch (IOException e) {
                Log.e("IO ERR FROM LISTEN MSG", e.toString());
            } catch (Exception e) {
                Log.e("EX ERR FROM LISTEN MSG", e.toString());
            } finally {
                try{
                    clientSocket.close();
                    Log.w("CLIENT DISCONNECTED", "A client is disconnected.");
                }catch (IOException e){
                    Log.w("IO ERR DISCONNECTION", e.toString());
                }
            }
        }
    }

@Robert-很抱歉，我对Java不是很在行，你能更具体一点，或者至少展示一个代码示例吗？谢谢你，我非常感谢你的帮助。
new Thread(new SocketServerListenToMessage(socket)).start();

        protected Socket clientSocket = null;

                    byte[] lenBytes = new byte[4];
