尝试获取最后一个位置更新时调用requestLocationUpdates时尝试超时

Android Studio 3.4

FusedLocationProviderClient 得到纬度和纬度的坐标。

在下面的代码片段中,我试图通过请求位置更新来处理这个场景。但是,该应用程序将不会得到任何最后的更新,我想请求超时。我创造了 LocationResult setExpirationDuration 我想如果我把它设为10000毫秒,10秒后可能会超时,但什么也没发生。

 private fun getLocationFused() {
        fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this)

        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) !=
                PackageManager.PERMISSION_GRANTED &&
            ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) !=
                PackageManager.PERMISSION_GRANTED) {

            ActivityCompat.requestPermissions(this, arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION, android.Manifest.permission.ACCESS_COARSE_LOCATION), permissionRequestCode)
        }
        else {
            fusedLocationProviderClient.lastLocation.addOnSuccessListener(this) { location ->
                if(location != null) {
                    forecastPresenter.requestWeatherForecast(location.latitude, location.longitude)
                }
                else {
                    val locationCallback = object : LocationCallback() {
                        override fun onLocationResult(locationResult: LocationResult) {
                            forecastPresenter.requestWeatherForecast(locationResult.lastLocation.latitude, locationResult.lastLocation.longitude)
                            fusedLocationProviderClient.removeLocationUpdates(this)
                        }
                    }

                    val locationResult = LocationRequest()
                    locationResult.maxWaitTime = 10000
                    fusedLocationProviderClient.requestLocationUpdates(locationResult, locationCallback, null)
                }
            }.addOnFailureListener(this) {
                println(it.message)
            }.addOnCanceledListener(this) {
                println("Cancelled")
            }
        }
    }

如果事件在之后超时,将调用什么方法?会不会 onLocationResult 以nul返回 locationResult

非常感谢您的建议,
