///// 第一步:獲取NotificationManager
NotificationManager nm = (NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);
///// 第二步:定義Notification
Intent intent = new Intent(this, OtherActivity.class);
//PendingIntent是待執行的Intent
PendingIntent pi = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
Notification notification = new Notification.Builder(this)
.setContentTitle("title")
.setContentText("text")
.setSmallIcon(R.drawable.ic_launcher).setContentIntent(pi)
.build();
notification.flags = Notification.FLAG_NO_CLEAR;
/////第三步:啓動通知欄,第一個參數是一個通知的唯一標識
nm.notify(0, notification);
//關閉通知
//nm.cancel(0);
