Geofence不在Kotlin工作

Geofence不在Kotlin中工作，尽管相同的代码在Java中工作。 我是Kotlin的新手，因此无法理解这个问题。 其实我从一个活动MainActivity调用MainGeofence.kt服务类以下是代码

MainGeofence.kt 

  public class MainGeofence : IntentService("MyService"), LocationListener { internal var mGeofencePendingIntent: PendingIntent? = null private var mGeofenceList: ArrayList? = null private var mGoogleApiClient: GoogleApiClient? = null val TAG = "Activity" internal lateinit var mLocationRequest: LocationRequest internal var currentLatitude = <<lat value internal var currentLongitude = <<long value override fun onCreate() { super.onCreate() } override fun onHandleIntent(p0: Intent?) { mGeofenceList = ArrayList() if (GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS) { initGoogleAPIClient() createGeofences(currentLatitude, currentLongitude) } else { Log.e(TAG, "Your Device doesn't support Google Play Services.") } mLocationRequest = LocationRequest.create() .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY) .setInterval(1 * 1000) .setFastestInterval(1 * 1000) } public fun initGoogleAPIClient(): Unit { mGoogleApiClient = GoogleApiClient.Builder(this) .addApi(API) .addConnectionCallbacks(connectionAddListener) .addOnConnectionFailedListener(connectionFailedListener) .build() mGoogleApiClient?.connect() } private val connectionAddListener = object : GoogleApiClient.ConnectionCallbacks { @SuppressLint("MissingPermission") override fun onConnected(bundle: Bundle?) { Log.i(TAG, "onConnected") @SuppressLint("MissingPermission") val location = FusedLocationApi.getLastLocation(mGoogleApiClient) if (location == null) { FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this@MainGeofence) } else { //If everything went fine lets get latitude and longitude currentLatitude = location.latitude currentLongitude = location.longitude Log.i(TAG, currentLatitude.toString() + " WORKS " + currentLongitude) //createGeofences(currentLatitude, currentLongitude); //registerGeofences(mGeofenceList); } try { GeofencingApi.addGeofences( mGoogleApiClient, getGeofencingRequest(), getGeofencePendingIntent() ).setResultCallback(ResultCallback { status -> if (status.isSuccess) { Log.i(TAG, "Saving Geofence") } else { Log.e(TAG, "Registering geofence failed: " + status.statusMessage + " : " + status.statusCode) } }) } catch (securityException: SecurityException) { // Catch exception generated if the app does not use ACCESS_FINE_LOCATION permission. Log.e(TAG, "Error") } } override fun onConnectionSuspended(i: Int) { Log.e(TAG, "onConnectionSuspended") } } /** * Create a Geofence list */ fun createGeofences(latitude: Double, longitude: Double) { val id = UUID.randomUUID().toString() println("latnlon " + latitude + " " + longitude) val fence = Geofence.Builder() .setRequestId(id) .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER or Geofence.GEOFENCE_TRANSITION_EXIT) .setCircularRegion(latitude, longitude, 50f) .setExpirationDuration(Geofence.NEVER_EXPIRE) .build() mGeofenceList?.add(fence) } private fun getGeofencingRequest(): GeofencingRequest { val builder = GeofencingRequest.Builder() builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER) builder.addGeofences(mGeofenceList) return builder.build() } private fun getGeofencePendingIntent(): PendingIntent { // Reuse the PendingIntent if we already have it. if (mGeofencePendingIntent != null) { return mGeofencePendingIntent!! } val intent = Intent(this, GeofenceIntentService::class.java) // We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when // calling addGeofences() and removeGeofences(). return PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT) } private val connectionFailedListener = GoogleApiClient.OnConnectionFailedListener { Log.e(TAG, "onConnectionFailed") } override fun onLocationChanged(location: Location?) { if (location != null) { currentLatitude = location.latitude currentLongitude = location.longitude Log.i(TAG, "onLocationChanged") } } }

MainActivity.kt 

 override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) dummyBtn = findViewById(R.id.dummyBtn) dummyTv = findViewById(R.id.dummyTv) dummyBtn.setOnClickListener(View.OnClickListener { // startLocationUpdates() startService(Intent(this, MainGeofence::class.java)) ... }) .... }

和GeofenceIntentService.kt 

 public class GeofenceIntentService : IntentService("GeofenceIntentService") { private final var TAG: String = "Geofence" override fun onHandleIntent(intent: Intent?) { Log.i(TAG, "onHandleIntent") val geofencingEvent = fromIntent(intent) if (geofencingEvent.hasError()) { Log.e(TAG, "Goefencing Error " + geofencingEvent.errorCode) return } //Create AudioManager object to change phone profile var am: AudioManager = getSystemService(Context.AUDIO_SERVICE) as AudioManager // Get the transition type. val geofenceTransition = geofencingEvent.geofenceTransition Log.i(TAG, "geofenceTransition = " + geofenceTransition + " Enter : " + Geofence.GEOFENCE_TRANSITION_ENTER + "Exit : " + Geofence.GEOFENCE_TRANSITION_EXIT) when (geofenceTransition) { Geofence.GEOFENCE_TRANSITION_ENTER or Geofence.GEOFENCE_TRANSITION_DWELL -> { showNotification("Entered", "Entered the Location") am.setRingerMode(AudioManager.RINGER_MODE_VIBRATE) //put ringer to vibration } Geofence.GEOFENCE_TRANSITION_EXIT -> { showNotification("Exited", "Exited the Location") am.setRingerMode(AudioManager.RINGER_MODE_NORMAL) //put ringer to normal } else -> { println("oh cow's eye! something bad happened!") Log.e(TAG, "Error ") } } } fun showNotification(text: String, bigText: String) { // 1. Create a NotificationManager val notificationManager = this.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager // 2. Create a PendingIntent for AllGeofencesActivity val intent = Intent(this, MainActivity::class.java) intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP or Intent.FLAG_ACTIVITY_CLEAR_TOP) val pendingNotificationIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT) // 3. Create and send a notification val notification = NotificationCompat.Builder(this) .setSmallIcon(R.mipmap.ic_launcher) .setContentTitle("Title") .setContentText(text) .setContentIntent(pendingNotificationIntent) .setStyle(NotificationCompat.BigTextStyle().bigText(bigText)) .setPriority(NotificationCompat.PRIORITY_HIGH) .setAutoCancel(true) .build() notificationManager.notify(0, notification) } }

地理围栏很少火灾，也只有Exit一个。 但是代码在Java中是完美的。 这是语言还是实现的问题？ 非常感谢帮助！

我认为你的问题是onHandleIntent的when子句

你基本上有 

 when (x) { A or B -> { ... } C -> { ... } else -> { ... } }

我认为Geofence.GEOFENCE_TRANSITION_ENTER等是Inttypes，所以你最终使用中infix fun or(other: Int): Int (source)来调用“按位或” infix fun or(other: Int): Int (source) 。

我想你真正想要的是： 

 when (x) { A, B -> { ... } C -> { ... } else -> { ... } }
