Android客戶端只向java服務器發送一條消息

Question

我正在開發一個簡單的聊天應用程序。 Android客戶端和一個java桌面服務器。我面臨一個問題，即我的客戶端只向服務器發送一條消息。服務器代碼正在Java客戶端上工作，所以只有android代碼有一些問題。 Android客戶端

private static final int SERVERPORT = 5000; 
private static final String SERVER_IP = "10.0.2.2"; 
private Socket socket; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    new Thread(new ClientThread()).start(); 
    Button button = (Button) findViewById(R.id.button1); 
    button.setOnClickListener(new OnClickListener() { 
     EditText et = (EditText) findViewById(R.id.editText1); 
     public void onClick(View v) { 
      try { 

        PrintWriter out = new PrintWriter(new BufferedWriter(
         new OutputStreamWriter(socket.getOutputStream())), 
         true); 
        String str = et.getText().toString(); 


       out.println(str); 
      } catch (UnknownHostException e) { 

       e.printStackTrace(); 

      } catch (IOException e) { 

       e.printStackTrace(); 
      } 

     } 
    });  
} 



class ClientThread implements Runnable { 

    @Override 
    public void run() { 

     try { 

      InetAddress serverAddr = InetAddress.getByName(SERVER_IP); 

      socket = new Socket(serverAddr, SERVERPORT); 
         } 
     catch (UnknownHostException e1) { 
      e1.printStackTrace(); 
     } catch (IOException e1) { 
      e1.printStackTrace(); 
     } 

    } 

}

那是因爲你的線程完成其工作，它不再供您使用。
