Wie kann ich den Dialog zum Aktivieren des Standorts wie Google Maps anzeigen?

Ich verwende die neueste Version von Google Play Services (7.0) und habe die in der Anleitung angegebenen Schritte ausgeführt. Ich habe den Standortdialog wie unten aktiviert, der über die Schaltfläche "Nie" verfügt. Meine App benötigt zwingend einen Standort, daher möchte ich dem Benutzer nicht "nie" anzeigen, da ich, sobald der Benutzer auf "nie" klickt, überhaupt keinen Standort mehr erhalten oder keinen Standort mehr anfordern kann.

Wo, da Google Maps nur Ja- und Nein-Schaltflächen ohne Niemals-Schaltflächen hat, gibt es eine Idee, wie dies erreicht werden kann?

Das Bild meiner App

Bild von Google Map

LocationSettingsRequest.Builder verfügt über eine Methode setAlwaysShow(boolean show). Während das Dokument angibt, dass derzeit nichts unternommen wird (aktualisiert am 05.07.2015: Die aktualisierte Google-Dokumentation hat diesen Wortlaut entfernt), builder.setAlwaysShow(true);aktiviert die Einstellung das Verhalten von Google Maps:

Hier ist der Code, mit dem es funktioniert hat:

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;
            }
        }
    });
}

Ich möchte einige Änderungen an Kai's Antwort für diejenigen hinzufügen, die nach Ja / Nein-Schaltflächen suchen.

Deklarieren Sie diese Konstante in Ihrer Aktivität

protected static final int REQUEST_CHECK_SETTINGS = 0x1;

Rufen Sie settingsrequest()in Ihrem onStart ()

public void settingsrequest()
    {
        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(mGoogleApiClient, 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(MainActivity.this, REQUEST_CHECK_SETTINGS);
                        } 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;
                }
            }
        });
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
// Check for the integer request code originally supplied to startResolutionForResult().
            case REQUEST_CHECK_SETTINGS:
                switch (resultCode) {
                    case Activity.RESULT_OK:
                        startLocationUpdates();
                        break;
                    case Activity.RESULT_CANCELED:
                        settingsrequest();//keep asking if imp or do whatever
                        break;
                }
                break;
        }
    }

LocationServices.SettingsApi ist jetzt veraltet. Daher verwenden wir 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);

Überprüfen Sie dann, ob die aktuellen Standorteinstellungen erfüllt sind. Erstellen Sie die Aufgabe LocationSettingsResponse:

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

Fügen Sie dann Listener hinzu

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;
                            }
                        }
                    }
                });

OnActivityResult hinzugefügt

@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;
        }
    }

Sie können auch mehrere LocationRequests for Builder hinzufügen, um das Dialogfeld "GPS, Wi-Fi und Mobilfunknetze als Standort verwenden" zu erhalten, anstatt nur "GPS als Standort verwenden".

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());

Verwenden Sie in Kotlin diesen Code:

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableLoc()
    }
    private fun enableLoc() {
        googleApiClient = GoogleApiClient.Builder(this)
            .addApi(LocationServices.API)
            .addConnectionCallbacks(object : GoogleApiClient.ConnectionCallbacks {

            })
            .addOnConnectionFailedListener {
            }.build()
        googleApiClient?.connect()
        val locationRequest = LocationRequest.create()
        locationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY

                } catch (e: IntentSender.SendIntentException) {
                }
            }

    }
    override fun onActivityResult(
        requestCode: Int,

Bitte überprüfen Sie meine sehr einfache Lösung, um den Benutzerstandort in den Vordergrund zu stellen.

1. GPS-Einstellungsdialog
2. Benutzerstandort mit Live-Daten.
3. Die LocationUtility-Klasse ist ein Aktivitätslebenszyklus, bei dem die Standortaktualisierungen angehalten / fortgesetzt werden können.
4. Speicherort mit dem neuesten FusedLocationProviderClient
