Comment afficher le dialogue d'activation d'emplacement comme Google Maps?
J'utilise la dernière version de Google Play Services (7.0) et j'ai suivi les étapes décrites dans leur guide. J'ai activé la boîte de dialogue d'emplacement comme ci-dessous, qui comporte un bouton "jamais". Mon application doit impérativement être localisée, je ne veux donc pas montrer jamais à l'utilisateur, car une fois que l'utilisateur a cliqué sur "jamais", je ne peux plus obtenir d'emplacement ni de demande de localisation.
Où en tant que Google Maps n’a que des boutons oui et non sans jamais bouton, aucune idée de comment atteindre le même?
L'image de mon application 
L'image de Google Map 
LocationSettingsRequest.Builder a une méthode setAlwaysShow(boolean show). Bien que le document indique qu'il ne fait actuellement rien(mise à jour le 05/07/2015: la documentation mise à jour de Google a supprimé cette formulation), le réglage de builder.setAlwaysShow(true); activera le 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;
}
}
});
}
Je voudrais ajouter quelques changements à la réponse de kai pour ceux qui recherchent des boutons Oui/Non.

LocationServices.SettingsApi est obsolète maintenant, 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);
Ensuite, vérifiez si les paramètres d'emplacement actuel sont satisfaits. Créez la tâche LocationSettingsResponse:
Task<LocationSettingsResponse> task=LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());
Ajoutez ensuite l'auditeur
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;
}
}

Ola Cabs utilise la nouvelle API de paramètres pour réaliser cette fonctionnalité. Conformément à la nouvelle API, l'utilisateur n'est pas obligé d'accéder à la page des paramètres pour activer les services de localisation offrant une intégration transparente pour les mêmes. Veuillez lire ci-dessous pour plus de détails:
https://developers.google.com/Android/reference/com/google/Android/gms/location/SettingsApi
Vous pouvez également ajouter plusieurs LocationRequests for Builder pour obtenir la boîte de dialogue "Utiliser les réseaux GPS, Wi-Fi et mobile pour la localisation" au lieu de "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());
