How do I check if Location is turned on or off in my Kotlin Android app?

Question

My app contains the following code to check for permission to use the device's location services but I need some way of detecting if Location in the device is turned on or off and to turn it on if it is off.

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

//        selectedCounty = intent.getStringExtra("COUNTY")!!

        // Custom action bar code to return to list of counties
//        configureCustomActionBar()

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

            Log.d("Debug","Permission not granted")

            // Permission is not granted
            if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                    android.Manifest.permission.ACCESS_FINE_LOCATION)) {

                Toast.makeText(this, "Location needed for navigation", Toast.LENGTH_SHORT).show()

            } else {

                Log.d("Debug","Request Permission")

                // No explanation needed, we can request the permission.
                ActivityCompat.requestPermissions(this, arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION), REQUEST_CODE)
            }
        } else {

            // Permission has already been granted
            Log.d("Debug", "Permission already granted")

        }

    }

Although permission is granted I still need some way of turning Location on or prompting the user to manually turn it on.

final LocationManager manager = (LocationManager) getSystemService( Context.LOCATION_SERVICE );

if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
    buildAlertMessageNoGps();
}

private void buildAlertMessageNoGps() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
       .setCancelable(false)
       .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
           public void onClick(@SuppressWarnings("unused") final 
DialogInterface dialog, @SuppressWarnings("unused") final int id) {
               startActivity(new 
Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
           }
       })
       .setNegativeButton("No", new DialogInterface.OnClickListener() {
           public void onClick(final DialogInterface dialog, 
@SuppressWarnings("unused") final int id) {
                dialog.cancel();
           }
       });
 final AlertDialog alert = builder.create();
 alert.show();

}

            val locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager

            if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) == false) {

                // Alert user to switch Location on in Settings
                val builder = AlertDialog.Builder(this)

                // Set the alert dialog title
                builder.setTitle("Turn on \"Location\"")

                // Display a message on alert dialog
                builder.setMessage("\"Location\" is currently turned off. Turn on \"Location\" to enable navigation function in GoSiteUK")

                // Set a positive button and its click listener on alert dialog
                builder.setPositiveButton("OK"){dialog, which ->

                    val intent = Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS)
                    startActivity(intent)
                }

                // Display a negative button on alert dialog
                builder.setNegativeButton("Cancel"){dialog,which ->
                    val intent = Intent(this, CountriesActivity::class.java)
                    startActivity(intent)

                }

                // Finally, make the alert dialog using builder
                val dialog: AlertDialog = builder.create()

                // Display the alert dialog on app interface
                dialog.show()

How do I check if Location is turned on or off in my Kotlin Android app?
