        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)
            }
        }
    
    }

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()
