                this);

        //2.设置参数   对象链式操作
        mBuilder.setSmallIcon(R.drawable.ic_launcher); //设置小图标
        mBuilder.setContentTitle("hello title"); //设置标题
        mBuilder.setContentText("Hello content");//设置内容

        //3.创建一个意图对象
        Intent resultIntent = new Intent(this, OtherActivity.class);

        //4.创建TaskStackBuilder对象
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        //5.添加到stackBuilder对象中
        stackBuilder.addParentStack(OtherActivity.class);

        //6.添加到顶端
        stackBuilder.addNextIntent(resultIntent);


        //7.意图对象
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
        //8.设置意图对象
        mBuilder.setContentIntent(resultPendingIntent);

        // 9.获取NotificationManager对象
       NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        //10.发送通知
       mNotificationManager.notify(mId, mBuilder.build());
    


    private void oldNotify() 
        // 1.获取NotificationManager对象
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        // 2.定义通知
        Notification notification = new Notification();
        // 3.设置参数
        notification.icon = R.drawable.ic_launcher; // 设置图标
        notification.when = System.currentTimeMillis(); // 发送通知的时间
        // 定义意图
        Intent intent = new Intent(this, OtherActivity.class);
        // 意图 ：跨进程的意图
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                intent, PendingIntent.FLAG_UPDATE_CURRENT);

        // 设置通知的最新事件消息
        notification.setLatestEventInfo(this, "hello title", "hello content",
                pendingIntent);
        // 3.发通知
        manager.notify(1, notification);
