Question

我的客户端/服务器应用有问题。客户端在Android上，服务器是java应用程序。

当我在java桌面应用程序上启动服务器和客户端时，一切都很好。但是，当我启动Android应用程序时，有bug。来自服务器的消息在android上可见，但消息（来自android本身或其他客户端）不是。

Android app look || What communicates should be here

没有错误，但消息不会显示。

@Update 在android上我也看不到来自客户端本身的消息，也来自其他聊天客户端的消息。我只看到有人加入聊天。我认为沟通有问题吗？但我不知道是什么。

@ UPDATE2 我注意到程序没有执行这部分代码

 protected Void doInBackground(String... params)
        {
            message = params[0].toString();
            Log.e("CLIENT","Message In Background: "+message);
            if (out != null && !out.checkError()) {
                out.println(message);
                out.flush();
                Log.e("CLIENT","Message send"+message);
            }
            return null;
        }

我调用它但在日志监视器中我没有收到来自Sender类的消息

Log.e("CLIENT","Create sender");
Sender sender = new Sender();
sender.execute(message);
Log.e("CLIENT","sender.execute");

消息：

因此它执行 sender.execute（消息）;

如何重复？

MainActivity

 public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

        arrayList = new ArrayList<String>();

        final EditText editText = (EditText) findViewById(R.id.editText);
        Button send = (Button)findViewById(R.id.send_button);

        mList = (ListView)findViewById(R.id.list);
        mAdapter = new MyCustomAdapter(this, arrayList);
        mList.setAdapter(mAdapter);

        new connectTask().execute("");        
        send.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {

                String message = editText.getText().toString();
                if (mClient != null) {
                    mClient.sendMessage(message);
                }
                mAdapter.notifyDataSetChanged();
                editText.setText("");
            }
        });

    }


    public class connectTask extends AsyncTask<String,String,Client> {

            @Override
            protected Client doInBackground(String... message) {
                mClient = new 

            Client(new Client.OnMessageReceived() {

                @Overrid
                public void messageReceived(String message) {
                    publishProgress(message);
                }
            });
            mClient.run();            
            return null;
        }

        @Override
        protected void onProgressUpdate(String... values) {
            super.onProgressUpdate(values);
            arrayList.add(values[0]);
            mAdapter.notifyDataSetChanged();
        }
    }

客户端类

public void sendMessage(String message)
    {
        Sender sender = new Sender();
        sender.execute(message);
    }


public void run() {
        mRun = true;
        try {
            InetAddress serverAddr = InetAddress.getByName(SERVERIP);
            Log.e("serverAddr", serverAddr.toString());
            Log.e("TCP Client", "C: Connecting...");
            Socket socket = new Socket(serverAddr, SERVERPORT);
            Log.e("TCP Server IP", SERVERIP);
            try {
                out = new PrintWriter(new BufferedWriter(
                        new OutputStreamWriter(socket.getOutputStream())), true);
                Log.e("TCP Client", "C: Sent.");
                Log.e("TCP Client", "C: Done.");
                in = new BufferedReader(new InputStreamReader(
                        socket.getInputStream()));
                while (mRun) {
                    serverMessage = in.readLine();
                    if (serverMessage != null && mMessageListener != null) {
                        mMessageListener.messageReceived(serverMessage);}
                    serverMessage = null;
                }
                Log.e("RESPONSE FROM SERVER", "S: Received Message: '"
                        + serverMessage + "'");
            } catch (Exception e) {Log.e("TCP", "S: Error", e);
                }finally {socket.close();}
                     } catch (Exception e) {Log.e("TCP", "C: Error", e);}        
    }

public class Sender extends AsyncTask<String, String, Void>
    {

        private String message;

        @Override
        protected Void doInBackground(String... params)
        {
            message = params[0].toString();            
            if (out != null && !out.checkError()) {
                out.println(message);
                out.flush();
            }
            return null;
        }
    }

也许您必须在发送的onClick中将消息添加到列表中？

[...]
arrayList.add(message);
mAdapter.notifyDataSetChanged();
[...]

Android聊天消息不会显示
