Comment afficher la boîte de dialogue d'activation de l'emplacement comme Google Maps?

J'utilise la dernière version des services Google Play (7.0) et ai suivi les étapes données dans leur guide et j'ai activé la boîte de dialogue de localisation comme ci-dessous, qui a un bouton "jamais". Mon application a obligatoirement besoin d'un emplacement, donc je ne veux pas montrer «jamais» à l'utilisateur, car une fois que l'utilisateur clique sur «jamais», je ne parviens plus du tout à obtenir l'emplacement ou à demander l'emplacement.

Où, comme Google Maps n'a que des boutons oui et non sans bouton jamais, une idée de comment y parvenir?

LocationSettingsRequest.Builder a une méthode setAlwaysShow(boolean show). Bien que le document indique qu'il ne fait actuellement rien (mise à jour 05/07/2015: la documentation Google mise à jour a supprimé ce libellé), le paramètre activera le builder.setAlwaysShow(true);comportement de Google Maps:

Voici le code qui l'a fait fonctionner:

if (googleApiClient == null) {
    googleApiClient = new GoogleApiClient.Builder(getActivity())
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).build();
    googleApiClient.connect();

    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(30 * 1000);
    locationRequest.setFastestInterval(5 * 1000);
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    //**************************
    builder.setAlwaysShow(true); //this is the key ingredient
    //**************************

    PendingResult<LocationSettingsResult> result =
            LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            final LocationSettingsStates state = result.getLocationSettingsStates();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS:
                    // All location settings are satisfied. The client can initialize location
                    // requests here.
                    break;
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    // Location settings are not satisfied. But could be fixed by showing the user
                    // a dialog.
                    try {
                        // Show the dialog by calling startResolutionForResult(),
                        // and check the result in onActivityResult().
                        status.startResolutionForResult(
                                getActivity(), 1000);
                    } catch (IntentSender.SendIntentException e) {
                        // Ignore the error.
                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                    // Location settings are not satisfied. However, we have no way to fix the
                    // settings so we won't show the dialog.
                    break;
            }
        }
    });
}

                        // requests here.
                        break;

                        // a dialog.

                            status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
                        } catch (IntentSender.SendIntentException e) {

                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way to fix the
                        // settings so we won't show the dialog.
                        break;

                break;

    }

LocationServices.SettingsApi est désormais obsolète, nous utilisons donc SettingsClient

    LocationRequest mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(10);
        mLocationRequest.setSmallestDisplacement(10);
        mLocationRequest.setFastestInterval(10);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        LocationSettingsRequest.Builder builder = new 
        LocationSettingsRequest.Builder();
        builder.addLocationRequest(mLocationRequest);

Vérifiez ensuite si les paramètres de localisation actuels sont satisfaits. Créez la tâche LocationSettingsResponse:

        Task<LocationSettingsResponse> task=LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());

Puis ajoutez Listener

task.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
            @Override
                    public void onComplete(Task<LocationSettingsResponse> task) {
                        try {
                            LocationSettingsResponse response = task.getResult(ApiException.class);
                            // All location settings are satisfied. The client can initialize location
                            // requests here.

                        } catch (ApiException exception) {
                            switch (exception.getStatusCode()) {
                                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                                    // Location settings are not satisfied. But could be fixed by showing the
                                    // user a dialog.
                                    try {
                                        // Cast to a resolvable exception.
                                        ResolvableApiException resolvable = (ResolvableApiException) exception;
                                        // Show the dialog by calling startResolutionForResult(),
                                        // and check the result in onActivityResult().
                                        resolvable.startResolutionForResult(
                                                HomeActivity.this,
                                                101);
                                    } catch (IntentSender.SendIntentException e) {
                                        // Ignore the error.
                                    } catch (ClassCastException e) {
                                        // Ignore, should be an impossible error.
                                    }
                                    break;
                                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                                    // Location settings are not satisfied. However, we have no way to fix the
                                    // settings so we won't show the dialog.
                                    break;
                            }
                        }
                    }
                });

Ajouté onActivityResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
        switch (requestCode) {
            case 101:
                switch (resultCode) {
                    case Activity.RESULT_OK:
                        // All required changes were successfully made
                        Toast.makeText(HomeActivity.this,states.isLocationPresent()+"",Toast.LENGTH_SHORT).show();
                        break;
                    case Activity.RESULT_CANCELED:
                        // The user was asked to change settings, but chose not to
                        Toast.makeText(HomeActivity.this,"Canceled",Toast.LENGTH_SHORT).show();
                        break;
                    default:
                        break;
                }
                break;
        }
    }

Vous pouvez également ajouter plusieurs demandes de localisation pour Builder pour obtenir la boîte de dialogue "Utiliser le GPS, le Wi-Fi et les réseaux mobiles pour la localisation" au lieu de simplement "Utiliser le GPS pour la localisation"

LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                .addLocationRequest(createLocationRequest(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY))
                .addLocationRequest(createLocationRequest(LocationRequest.PRIORITY_HIGH_ACCURACY))
                .setAlwaysShow(true);

PendingResult<LocationSettingsResult> result =
                LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
