生手handlemessage（）没调用

新手handlemessage（）没调用
public class Handler22Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.main);
System.out.println("dang qian BB xiancheng ID:"+Thread.currentThread().getId());
System.out.println("dang qian BB xiancheng name:"+Thread.currentThread().getName());

HandlerThread ht =new HandlerThread("ht");
ht.start();
t t1 =new t(ht.getLooper());
Message mess=t1.obtainMessage();
//mess.sendToTarget();
t1.sendMessage(mess);
}
class t extends Handler{
//public t(){};
public t(Looper looper){
super(looper);
}

public void handlemessage(Message mess){
System.out.println("dang qian AA xiancheng ID:"+Thread.currentThread().getId());
System.out.println("dang qian AA xiancheng name:"+Thread.currentThread().getName());

}
}

}
为什么打印不出dang qian AA xiancheng ID:这语句，好像handlemessage没有调用，初学android，大家帮我看看吧！谢谢。。

------解决方案--------------------

Java code


               @Override
        public void dispatchMessage(Message msg) {
            System.out.println("dang qian AA xiancheng ID:" + Thread.currentThread().getId());
            System.out.println("dang qian AA xiancheng name:" + Thread.currentThread().getName());
            super.dispatchMessage(msg);
        }

------解决方案--------------------

Java code


public class HandlerActivity extends Activity {
  /** Called when the activity is first created. */
//声明一个按钮控件
private Button startButton = null;
public int [color=#FF0000]i[/color]=0;
  @Override
  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  startButton = (Button)findViewById(R.id.startButton);
  startButton.setOnClickListener(new StartButtonListener());
   
  }
  class StartButtonListener implements OnClickListener{

@Override
public void onClick(View v) {
//调用Handler的post方法，将要执行的线程对象添加到队列当中
if([color=#FF0000]i[/color]<6)
handler.post(updateThread);
else
handler.removeCallbacks(updateThread);
}
 
  }
   
  //创建一个Handler对象
  Handler handler = new Handler();
  //将要执行的操作写在线程对象的run方法当中
  Runnable updateThread = new Runnable(){
  int [color=#00FF00]i[/color]=0;
@Override
public void run() {
[color=#00FF00]i[/color]=[color=#00FF00]i[/color]+1;
System.out.println("UpdateThread:"+i);

}
 
  };
}

------解决方案--------------------
i每次都被初始化了~~~
