class NoticeActivity: AppCompatActivity() {
    private lateinit var noticeBinding: ActivityNoticeBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        noticeBinding= ActivityNoticeBinding.inflate(layoutInflater)
        setContentView(noticeBinding.root)

        noticeBinding.messageSend.setOnClickListener {
            val intent=Intent(this,NoticeService::class.java)
            startService(intent)
        }
    }

}

​​NoticeOtherActivity:​​

class NoticeOtherActivity: AppCompatActivity() {
    private lateinit var noticeOtherBinding: ActivityNoticeOtherBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        noticeOtherBinding=ActivityNoticeOtherBinding.inflate(layoutInflater)
        setContentView(noticeOtherBinding.root)

        noticeOtherBinding.noticeOtherCloseService.setOnClickListener {
            val intent=Intent(this,NoticeService::class.java)
            stopService(intent)
        }
    }
}

​​NoticeService:​​

class NoticeService : Service() {
    private val mBinder = MyBinder()

    class MyBinder : Binder() {

    }

    override fun onBind(intent: Intent?): IBinder? {
        return mBinder
    }

    override fun onCreate() {
        super.onCreate()

        val manager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val channel = NotificationChannel(
                "my_service",
                "前台Service通知",
                NotificationManager.IMPORTANCE_DEFAULT
            )
            manager.createNotificationChannel(channel)
        }

        val intent = Intent(this, NoticeOtherActivity::class.java)
        val pi = PendingIntent.getActivity(this, 0, intent, 0)
        val notification = NotificationCompat.Builder(this, "my_service")
            .setContentTitle("This is title")
            .setContentText("This is content text")
            .setSmallIcon(R.drawable.ic_launcher_background)
            .setLargeIcon(
                BitmapFactory.decodeResource(
                    resources,
                    R.drawable.ic_launcher_background
                )
            )
            .setContentIntent(pi)
            .build()
        startForeground(1, notification)
    }

    override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
        return super.onStartCommand(intent, flags, startId)
    }

    override fun onDestroy() {
        super.onDestroy()
    }
}
