收听ObjectInputStream android

所以我要做一个回合制游戏，玩家通过网络连接。玩家将发送一个对象，其中包含他们在回合中所做的事情。我已经实现了两个模拟器之间的连接，一个服务器和另一个客户端。我正在使用套接字（TCP）

我现在不明白的是如何监听发送到ObjectInputStream的对象，以便在发送和接收新对象时，我可以对对象的内容进行操作。 所以，也许我想要的是一个监听流内消息的侦听器，可能是另一个线程，但是如何呢？ 有什么想法吗

我正在使用的代码

ClientActivity.java:

public class ClientActivity extends Activity {
private EditText et;
private Client c;
private TextView tv;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    et =(EditText)findViewById(R.id.clientTxt);
    tv = (TextView)findViewById(R.id.recievedTxt);

    c = new Client(tv);
    c.start();

    try {
        tv.setText(c.setText());
    } catch (Exception e) {}
}

}
