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。。

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);        }

i每次都被初始化了~~~
