HandlerThread的用法

/* {

HandlerThread ht = new HandlerThread("MyThread"); 
        ht.start(); 
       handler = new Handler(ht.getLooper(), new Handler.Callback() { 
           @Override 
         public boolean handleMessage(Message msg) { 
               // TODO Auto-generated method stub 
              int tmp = msg.arg1; 
               System.out.println(Thread.currentThread().getId() + "::::::::::::" + tmp); 
              return false; 
           } 
      }); 

@Override
public void handleMessage(Message msg) {
switch(msg.what) {
case 0:
map.put("commend", true);
commBtn.setBackgroundResource(R.drawable.comm_pressed);
break;
default:break;
}
super.handleMessage(msg);
}
});*/
