Wykonaj kroki wymienione poniżej

1) Utwórz LocationRequest zgodnie z Twoim życzeniem

LocationRequest mLocationRequest = LocationRequest.create()
           .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
           .setInterval(10 * 1000)
           .setFastestInterval(1 * 1000);

2) Utwórz LocationSettingsRequest.Builder

LocationSettingsRequest.Builder settingsBuilder = new LocationSettingsRequest.Builder()
               .addLocationRequest(mLocationRequest);
settingsBuilder.setAlwaysShow(true);

3) Get LocationSettingsResponse Task użycie następującego kodu

Task<LocationSettingsResponse> result = LocationServices.getSettingsClient(this)
              .checkLocationSettings(settingsBuilder.build());

Uwaga: LocationServices.SettingsApi jest przestarzałe, więc zamiast tego użyj SettingsClient.

4) dodaj OnCompleteListener, aby uzyskać wynik zadania.Po zakończeniu Task, klient może sprawdzić ustawienia lokalizacji, patrząc na kod statusu z LocationSettingsResponse obiekt.

result.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
    @Override
    public void onComplete(@NonNull Task<LocationSettingsResponse> task) {
    try {
        LocationSettingsResponse response = 
                          task.getResult(ApiException.class);
        } catch (ApiException ex) {
            switch (ex.getStatusCode()) {
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    try {
                        ResolvableApiException resolvableApiException = 
                                 (ResolvableApiException) ex;
                            resolvableApiException
                                   .startResolutionForResult(MapsActivity.this, 
                                         LOCATION_SETTINGS_REQUEST);
                    } catch (IntentSender.SendIntentException e) {

                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:

                    break;
            }
        }
    }
});  

CASE 1: LocationSettingsStatusCodes.RESOLUTION_REQUIRED : Lokalizacja nie jest włączona, ale możemy poprosić Użytkownika o włączenie lokalizacji, prosząc go o włączenie lokalizacji w oknie dialogowym (wywołując startResolutionForResult).

CASE 2: LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE : ustawienia lokalizacji nie są spełnione. Jednak nie mamy sposobu, aby naprawić ustawienia, więc nie pokażemy okna dialogowego.

5) OnActivityResult możemy uzyskać akcję użytkownika w oknie ustawień lokalizacji. RESULT_OK => Użytkownik włączył lokalizację. RESULT_CANCELLED - użytkownik odrzucił żądanie ustawienia lokalizacji.

Jego działanie jest podobne do google maps

Dziękuję Mattia Maestrini za odpowiedź, chciałbym dodać, że za pomocą

Dodaj build.gradle(Module:app)

Następnie utwórz tę funkcję

        .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
        .setInterval(2000)

    val settingsBuilder = LocationSettingsRequest.Builder()
        .addLocationRequest(mLocationRequest)
    settingsBuilder.setAlwaysShow(true)

    val result = LocationServices.getSettingsClient(this).checkLocationSettings(settingsBuilder.build())
    result.addOnCompleteListener { task ->

                    resolvableApiException.startResolutionForResult(this,REQUEST_CHECK_SETTINGS
                    )

Z najnowszą aktualizacją Marshmallow, nawet jeśli ustawienie lokalizacji jest włączone, aplikacja będzie wymagać wyraźnego poproszenia o pozwolenie. Zalecanym sposobem na to jest pokazanie sekcji Uprawnienia aplikacji, w której użytkownik może przełączyć uprawnienia Zgodnie z wymaganiami. Fragment kodu do zrobienia tego jest następujący:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    
    if (this.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Location Permission");
        builder.setMessage("The app needs location permissions. Please grant this permission to continue using the features of the app.");
        builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, PERMISSION_REQUEST_COARSE_LOCATION);
    
            }
        });
        builder.setNegativeButton(android.R.string.no, null);
        builder.show();
    }
} else {
    // do programatically as show in the other answer 
}

I nadpisać metodę onRequestPermissionsResult Jak poniżej:

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case PERMISSION_REQUEST_COARSE_LOCATION: {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.d(TAG, "coarse location permission granted");
                } else {
                    Intent intent = new Intent();
                    intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                    Uri uri = Uri.fromParts("package", getPackageName(), null);
                    intent.setData(uri);
                    startActivity(intent);
                }
            }
        }
    }

Innym podejściem jest to, że możesz również użyć SettingsApi , aby dowiedzieć się, który dostawca lokalizacji) są włączone. Jeśli opcja brak jest włączona, możesz wyświetlić okno dialogowe z prośbą o zmianę Ustawienia w aplikacji.

Najprostszym sposobem, jaki znalazłem podczas moich badań, jest stworzenie klasy Util dla tego procesu żądającego lokalizacji, a następnie wywołanie go, aby włączyć gps dla nas.
