在Android 9虚拟机上实现Notification通知

在尝试了网上各种向通知栏发送通知的教程后,发现能用的教程的很少,但是皇天不负有心人,最后还是找到一篇很实用的教程,

接下来记录下我的简单的demo,实现点击按钮向通知栏发送通知,但是关于点击通知的处理,暂时被我省略了,

因为的目的是成功发送通知:

所以代码只贴了点击事件处理的代码,也是发送通知的关键性代码

        String id = "channel_001";
        String name = "name";
        NotificationManager notificationManager = (NotificationManager)
                this.getSystemService(NOTIFICATION_SERVICE);

        Notification notification = null;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {//判断API
            NotificationChannel mChannel = new NotificationChannel(id, name, NotificationManager.IMPORTANCE_LOW);
            notificationManager.createNotificationChannel(mChannel);
            notification = new Notification.Builder(this)
                    .setChannelId(id)
                    .setContentTitle("活动")
                    .setContentText("您有一项新活动")
                    .setSmallIcon(R.mipmap.ic_launcher_round).build();
        }else{
            NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                    .setContentTitle("活动")
                    .setContentText("您有一项新活动")
                    .setSmallIcon(R.mipmap.ic_launcher_round)
                    .setOngoing(true)
                    .setChannelId(id);//无效
            notification = notificationBuilder.build();
        }

        notificationManager.notify(1,notification);

运行结果:
