notification 写好了，但是没有反应，运行也没有报错

    nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);      Intent intent = new Intent(this,EU.class);      pd = PendingIntent.getActivity(EU.this, 0, intent, 0);     bt01 = (Button)findViewById(R.id.button1);    OnClickListener onclick = new OnClickListener() {          @SuppressWarnings("deprecation")        @Override          public void onClick(View v) {              baseNF = new Notification();              baseNF.tickerText = "You clicked BaseNF!";             baseNF.setLatestEventInfo(EU.this, "Title01", "Content01", pd);             nm.notify(1, baseNF);         }    };    bt01.setOnClickListener(onclick);

不知道是哪里有问题呢？请高人指教。谢谢。代码是写在 super.onCreate(savedInstanceState);下的
