无法访问“<init>”：它在“LocationRequest”中是私有的

Question

我是 Kotlin 的新手，我正在尝试实时获取位置并在 toast 中显示坐标。问题是我无法继续使用代码，因为它没有检测到 IniciartLocationRequest() 函数中的 LocationRequest ()。有什么想法吗？

下面的代码是mainActivity（还有待完成）

package com.example.ubicacion

import android.annotation.SuppressLint
import android.content.pm.PackageManager
import android.location.LocationRequest
import android.os.Bundle
import android.os.Looper
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import androidx.core.app.ActivityCompat
import com.google.android.gms.location.FusedLocationProviderClient
import com.google.android.gms.location.LocationCallback
import com.google.android.gms.location.LocationResult
import com.google.android.gms.location.LocationServices

class MainActivity : AppCompatActivity() {

    private val permisoFineLocation = android.Manifest.permission.ACCESS_FINE_LOCATION
    private val permisoCoarseLocation = android.Manifest.permission.ACCESS_COARSE_LOCATION

    private val codigoSolicitudPermiso = 100

    private lateinit var fusedLocationClient: FusedLocationProviderClient
    private lateinit var locationRequest: LocationRequest

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        fusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
        iniciarLocationRequest()
    }

    private fun iniciarLocationRequest() {
        locationRequest = LocationRequest()


    }

    private fun validarPermisosUbicacion(): Boolean {
        val hayUbicacionPrecisa = ActivityCompat.checkSelfPermission(
            this,
            permisoFineLocation
        ) == PackageManager.PERMISSION_GRANTED
        val hayUbicacionOrdinaria = ActivityCompat.checkSelfPermission(
            this,
            permisoCoarseLocation
        ) == PackageManager.PERMISSION_GRANTED

        return hayUbicacionPrecisa && hayUbicacionOrdinaria
    }

    @SuppressLint("MissingPermission")
    private fun obtenerUbicacion() {
        /*fusedLocationClient?.lastLocation?.addOnSuccessListener(this,
            object : OnSuccessListener<Location> {
                override fun onSuccess(p0: Location?) {
                    if (p0 != null) {
                        Toast.makeText(
                            applicationContext,
                            p0.latitude.toString() + "-" + p0.longitude.toString(),
                            Toast.LENGTH_LONG
                        ).show()
                    }
                }
            })*/

        val callback = object : LocationCallback() {

            override fun onLocationResult(p0: LocationResult) {
                super.onLocationResult(p0)
                for (ubicacion in p0.locations) {
                    Toast.makeText(applicationContext, "a", Toast.LENGTH_SHORT).show()
                }
            }
        }
        fusedLocationClient.requestLocationUpdates(
            locationRequest,
            callback,
            Looper.getMainLooper()
        )
    }

    private fun pedirPermisos() {
        val deboProveerContexto =
            ActivityCompat.shouldShowRequestPermissionRationale(this, permisoFineLocation)

        if (deboProveerContexto) {
            //Mandar mensaje con expliacion adicinal
            solicitudPermiso()
        } else {
            solicitudPermiso()
        }
    }

    private fun solicitudPermiso() {
        requestPermissions(
            arrayOf(permisoCoarseLocation, permisoFineLocation),
            codigoSolicitudPermiso
        )
    }

    override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)

        when (requestCode) {
            codigoSolicitudPermiso -> {
                if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    //obtener Ubicacion
                    obtenerUbicacion()
                } else {
                    Toast.makeText(
                        this,
                        "No se dio permiso para acceder a la ubicacion",
                        Toast.LENGTH_SHORT
                    ).show()
                }
            }
        }
    }

    override fun onStart() {
        super.onStart()

        if (validarPermisosUbicacion()) {
            obtenerUbicacion()
        } else {
            pedirPermisos()
        }
    }

你从LocationRequest.Builder得到LocationRequest
