  先看例子

<span style="font-size:18px;">private void showNotify(){    Notification notice=new Notification();    notice.icon=R.drawable.icon;    notice.tickerText="您有一条新的信息";    notice.defaults=Notification.DEFAULT_SOUND;    notice.when=10L;    // 100 毫秒延迟后，震动 250 毫秒，暂停 100 毫秒后，再震动 500 毫秒      //notice.vibrate = new long[] { 100, 250, 100, 500 };出错？    //notice.setLatestEventInfo(this, "通知", "开会啦", PendingIntent.getActivity(this, 0, null, 0));        notice.setLatestEventInfo(this, "通知", "开会啦", PendingIntent.getActivity(this, 0, new Intent(this,otherAct        ivity.class,null);<span style="color:#cc0000;">//即将跳转页面，还没跳转，这时Intent已经交给了NotigicationManager处理了。</span></span><pre name="code" class="java"><span style="font-size: 18px;">       </span><span style="font-family: Arial, Helvetica, sans-serif;">//获取系统通知服务</span>

NotificationManager manager=(NotificationManager)getSystemService(this.NOTIFICATION_SERVICE); manager.notify(0,notice); }

      例子中Intent什么时候开始被处理呢?应该在manager.notify(0,notice)中被处理，此时manager通过调用传进来的notice中的PendingIntent的send()方法。PendingIntent.send(){

方法中可以做这样处理，源程序Context.startActivity(Intent);  }

    什么时候调用就要看NotificationManager了。

    发送短信的例子：

private final static String SEND_ACTION      = "send";private final static String DELIVERED_ACTION = "delivered";private void sendSms(String receiver, String text) {    SmsManager s = SmsManager.getDefault();    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SEND_ACTION),                                                      PendingIntent.FLAG_CANCEL_CURRENT);    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED_ACTION),                                                           PendingIntent.FLAG_CANCEL_CURRENT);    // 发送完成    registerReceiver(new BroadcastReceiver() {        @Override        public void onReceive(Context context, Intent intent) {            switch (getResultCode()) {                case Activity.RESULT_OK:                    Toast.makeText(getBaseContext(), "Send Success!", Toast.LENGTH_SHORT).show();                    break;                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:                    Toast.makeText(getBaseContext(), "Send Failed because generic failure cause.",                                   Toast.LENGTH_SHORT).show();                    break;                case SmsManager.RESULT_ERROR_NO_SERVICE:                    Toast.makeText(getBaseContext(), "Send Failed because service is currently unavailable.",                                   Toast.LENGTH_SHORT).show();                    break;                case SmsManager.RESULT_ERROR_NULL_PDU:                    Toast.makeText(getBaseContext(), "Send Failed because no pdu provided.", Toast.LENGTH_SHORT).show();                    break;                case SmsManager.RESULT_ERROR_RADIO_OFF:                    Toast.makeText(getBaseContext(), "Send Failed because radio was explicitly turned off.",                                   Toast.LENGTH_SHORT).show();                    break;                default:                    Toast.makeText(getBaseContext(), "Send Failed.", Toast.LENGTH_SHORT).show();                    break;            }        }    }, new IntentFilter(SEND_ACTION));    // 对方接受完成    registerReceiver(new BroadcastReceiver() {        @Override        public void onReceive(Context context, Intent intent) {            switch (getResultCode()) {                case Activity.RESULT_OK:                    Toast.makeText(getBaseContext(), "Delivered Success!", Toast.LENGTH_SHORT).show();                    break;                default:                    Toast.makeText(getBaseContext(), "Delivered Failed!", Toast.LENGTH_SHORT).show();                    break;            }        }    }, new IntentFilter(DELIVERED_ACTION));    // 发送短信，sentPI和deliveredPI将分别在短信发送成功和对方接受成功时被广播    s.sendTextMessage(receiver, null, text, sentPI, deliveredPI);}
