Notification的例子，请参考附件。

1. 创建Notification builder


NotificationCompat.Builder mBuilder =
    new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.notification_icon) // 一个图标
    .setContentTitle("My notification")         // 标题
    .setContentText("Hello World!");            // 具体内容

2. 定义notification action


Intent resultIntent = new Intent(this, ResultActivity.class); // 点击后跳转的activity
...
// Because clicking the notification opens a new ("special") activity, there's
// no need to create an artificial back stack.
PendingIntent resultPendingIntent =
    PendingIntent.getActivity(
    this,
    0,
    resultIntent,
    PendingIntent.FLAG_UPDATE_CURRENT
);

3. 设置notification点击的行为


PendingIntent resultPendingIntent;
...
mBuilder.setContentIntent(resultPendingIntent);

4. 启动notification


NotificationCompat.Builder mBuilder;
...
// Sets an ID for the notification
int mNotificationId = 001;
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr = 
        (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(mNotificationId, mBuilder.build());

5. 取消notification


NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

   	nm.cancel(NOTIFICATION_ID);
