Diálogo LocationSettingsRequest para habilitar GPS-onActivityResult() omitido

Question

Parte de mi aplicación requiere servicios de ubicación, por lo que si la ubicación está actualmente desactivada, la aplicación solicitará al usuario que la habilite. Así es como lo estoy haciendo: (También visto en this respuesta de Desbordamiento de pila)

LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
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 = result.getLocationSettingsStates();
switch (status.getStatusCode())
{
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
...
Log.d("onResult", "SUCCESS");
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
Log.d("onResult", "RESOLUTION_REQUIRED");
try
{
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(OuterClass.this, REQUEST_LOCATION);
}
catch (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.
...
Log.d("onResult", "UNAVAILABLE");
break;
}
}
});
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
// This log is never called
Log.d("onActivityResult()", Integer.toString(resultCode));
final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode)
{
case REQUEST_LOCATION:
switch (resultCode)
{
case Activity.RESULT_OK:
{
// All required changes were successfully made
break;
}
case Activity.RESULT_CANCELED:
{
// The user was asked to change settings, but chose not to
break;
}
default:
{
break;
}
}
break;
}
}

Este código funciona bien, sin embargo, onActivityResult() siempre se omite. Independientemente de si el usuario presiona Yes , No o back desde el Dialog , onActivityResult() no se ejecuta.

Necesito que Android onActivityResult() modo que si el usuario elige no activar los servicios de ubicación, puedo manejarlo adecuadamente.

La página de desarrollador de Google (y el código anterior) dice explícitamente que se debe llamar a onActivityResult() . Alguien sabe por qué se está omitiendo?

Tampoco sé cuál es el propósito de esta línea:

final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);

¡Gracias!

Editar: información básica sobre la estructura de mi aplicación:

• Este código está contenido dentro del método onResume() de un Fragment que implementa GoogleApiClient.ConnectionCallbacks , GoogleApiClient.OnConnectionFailedListener y LocationListener para recibir actualizaciones de ubicación. Ejemplo visto here .
• En onLocationChanged() el Fragment tendrá una llamada View personalizada invalidate() y se volverá a dibujar con información actualizada.

Answer 1

Es por todos los códigos de API de Google presentes en los Fragmentos. Intenta lo siguiente, te ayudará a superar ...

1.Cree un constructor vacío para sus fragmentos.

2.necesita el método oncreate () antes de onCreateView () ...

3.pega el código de la API de Google dentro de oncreate () ....

Answer 2

Guardar el campo de fragmentos en la actividad (como sugirió Daniel) no suele ser una buena decisión, porque imagina que tienes varios fragmentos y cada uno contiene un código de ubicación. Lo hice de una manera diferente:

public class MainActivity extends Activity implements PlaceFragment.SettingsModifyHandler { private static final int LOCATION_SETTINGS_RESULT = 1; private OnResultCallback placeCallback; ... @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == LOCATION_SETTINGS_RESULT) { if (resultCode == Activity.RESULT_OK) { placeCallback.resultOk(); } else { placeCallback.resultFail(); } placeCallback = null; } } @Override public void handle(IntentSender intentSender, OnResultCallback callback) { placeCallback = callback; try { startIntentSenderForResult(intentSender, LOCATION_SETTINGS_RESULT, null, 0, 0, 0); } catch (IntentSender.SendIntentException e) { callback.resultFail(); } } } public class PlaceFragment extends Fragment { private SettingsModifyHandler settingsModifyHandler; ... @Override public void onAttach(Activity activity) { super.onAttach(activity); if (context instanceof SettingsModifyHandler) { settingsModifyHandler = (SettingsModifyHandler) context; } else { throw new RuntimeException("Parent activity must implement PlaceFragment.SettingsModifyHandler interface"); } } /* Callback from module, where you implemented status.getStatusCode().LocationSettingsStatusCodes.RESOLUTION_REQUIRED case (status is instance of com.google.android.gms.common.api.Status) You provide intentSender here through status.getResolution().getIntentSender() */ @Override public void placeLoadError(IntentSender sender) { TextView view_text = (TextView) root.findViewById(R.id.text_error); TextView view_btn = (TextView) root.findViewById(R.id.btn_reply); view_text.setText("Need to change location settings"); view_btn.setText("Change"); view_btn.setOnClickListener(v -> { settingsModifyHandler.handle(sender, new SettingsModifyHandler.OnResultCallback() { @Override public void resultOk() { presenter.loadPlace(placeId); } @Override public void resultFail() { ToastUtils.show("You should change location settings!"); } }); }); } public interface SettingsModifyHandler { void handle(IntentSender intentSender, OnResultCallback callback); interface OnResultCallback { void resultOk(); void resultFail(); } } }

Answer 3

Necesita agregar esto a su devolución de llamada de resultados:

 public mainFragment(){
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
buildGoogleApiClient();
buildLocationSettingsRequest();
checkLocationSettings();
mGoogleApiClient.connect();
} catch (Exception e) {
e.printStackTrace();
}
}

onActivityResult a onActivityResult en su fragmento, no necesita llamarlo manualmente en su actividad. Esto es esencialmente cómo funciona startResolutionForResult .

Answer 4

Si desea resultados de nuevo a su fragmento que usar

public class MainActivity extends Activity implements PlaceFragment.SettingsModifyHandler {
private static final int LOCATION_SETTINGS_RESULT = 1;
private OnResultCallback placeCallback;
...
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == LOCATION_SETTINGS_RESULT) {
if (resultCode == Activity.RESULT_OK) {
placeCallback.resultOk();
} else {
placeCallback.resultFail();
}
placeCallback = null;
}
}
@Override
public void handle(IntentSender intentSender, OnResultCallback callback) {
placeCallback = callback;
try {
startIntentSenderForResult(intentSender, LOCATION_SETTINGS_RESULT, null, 0, 0, 0);
} catch (IntentSender.SendIntentException e) {
callback.resultFail();
}
}
}
public class PlaceFragment extends Fragment {
private SettingsModifyHandler settingsModifyHandler;
...
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
if (context instanceof SettingsModifyHandler) {
settingsModifyHandler = (SettingsModifyHandler) context;
} else {
throw new RuntimeException("Parent activity must implement PlaceFragment.SettingsModifyHandler interface");
}
}
/* Callback from module, where you implemented status.getStatusCode().LocationSettingsStatusCodes.RESOLUTION_REQUIRED case
(status is instance of com.google.android.gms.common.api.Status)
You provide intentSender here through status.getResolution().getIntentSender() */
@Override
public void placeLoadError(IntentSender sender) {
TextView view_text = (TextView) root.findViewById(R.id.text_error);
TextView view_btn = (TextView) root.findViewById(R.id.btn_reply);
view_text.setText("Need to change location settings");
view_btn.setText("Change");
view_btn.setOnClickListener(v -> {
settingsModifyHandler.handle(sender, new SettingsModifyHandler.OnResultCallback() {
@Override
public void resultOk() {
presenter.loadPlace(placeId);
}
@Override
public void resultFail() {
ToastUtils.show("You should change location settings!");
}
});
});
}
public interface SettingsModifyHandler {
void handle(IntentSender intentSender, OnResultCallback callback);
interface OnResultCallback {
void resultOk();
void resultFail();
}
}
}

en lugar de status.startResolutionForResult(YourActivity, LOCATION_REQUEST);

El uso del método anterior devolverá el resultado solo a su fragmento.

Answer 5

Veo que utiliza diferentes constantes REQUEST_CHECK_SETTINGS y REQUEST_LOCATION para el código de solicitud. ¿Tienen el mismo valor?

Para el código: final LocationSettingsStates states = LocationSettingsStates.fromIntent(intent); .
El propósito del código anterior es obtener el estado actual de la configuración de Ubicación (como usar Red, GPS, ...) después de cambiar la configuración.
Además, en su código, creo que debería ser LocationSettingsStates.fromIntent(data); porque la intent no existe aquí, quizás sea solo un error tipográfico.

Answer 6

ACTUALIZAR

La respuesta original a continuación está utilizando Java y la ahora obsoleta Here .

Aquí hay un enfoque más moderno usando Kotlin y SettingsClient :

public class MainActivity extends AppCompatActivity{
LocationFragment lFrag;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lFrag = LocationFragment.newInstance();
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, lFrag).commit();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == LocationFragment.REQUEST_LOCATION){
lFrag.onActivityResult(requestCode, resultCode, data);
}
else {
super.onActivityResult(requestCode, resultCode, data);
}
}
}

En MainActivity, defina la constante:

public class LocationFragment extends Fragment
implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
PendingResult<LocationSettingsResult> result;
final static int REQUEST_LOCATION = 199;
public static LocationFragment newInstance() {
LocationFragment fragment = new LocationFragment();
return fragment;
}
public LocationFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_location, container, false);
}
@Override
public void onResume() {
super.onResume();
}
@Override
public void onConnected(Bundle bundle) {
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setInterval(30 * 1000);
mLocationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
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(
getActivity(),
REQUEST_LOCATION);
} 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
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
Log.d("onActivityResult()", Integer.toString(resultCode));
//final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode)
{
case REQUEST_LOCATION:
switch (resultCode)
{
case Activity.RESULT_OK:
{
// All required changes were successfully made
Toast.makeText(getActivity(), "Location enabled by user!", Toast.LENGTH_LONG).show();
break;
}
case Activity.RESULT_CANCELED:
{
// The user was asked to change settings, but chose not to
Toast.makeText(getActivity(), "Location not enabled, user cancelled.", Toast.LENGTH_LONG).show();
break;
}
default:
{
break;
}
}
break;
}
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
}

RESPUESTA ORIGINAL:

Parece que el problema principal es que tiene todo el código en un Fragmento, y dado que startResolutionForResult() necesita que se le pase una Actividad, la Actividad es lo que obtiene la devolución de llamada onActivityResult() .

Una forma de evitar esto es usar la técnica descrita here , llamar manualmente al método onActivityResult() del Fragmento desde la Actividad cuando llegue el resultado.

Acabo de hacer que este simple ejemplo funcione.

Primero, la Actividad, que agrega el Fragmento, y también tiene funcionalidad para transmitir el resultado de onActivityResult() al Fragmento:

public class MainActivity extends AppCompatActivity
implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
PendingResult<LocationSettingsResult> result;
final static int REQUEST_LOCATION = 199;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
}
@Override
public void onConnected(Bundle bundle) {
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setInterval(30 * 1000);
mLocationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
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_LOCATION);
} catch (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
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
Log.d("onActivityResult()", Integer.toString(resultCode));
//final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode)
{
case REQUEST_LOCATION:
switch (resultCode)
{
case Activity.RESULT_OK:
{
// All required changes were successfully made
Toast.makeText(MainActivity.this, "Location enabled by user!", Toast.LENGTH_LONG).show();
break;
}
case Activity.RESULT_CANCELED:
{
// The user was asked to change settings, but chose not to
Toast.makeText(MainActivity.this, "Location not enabled, user cancelled.", Toast.LENGTH_LONG).show();
break;
}
default:
{
break;
}
}
break;
}
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
}

Aquí está el Fragmento, que contiene toda la funcionalidad para mostrar el diálogo y manejar el resultado. En este simple ejemplo, acabo de usar mensajes Toast para verificar que funciona como se esperaba. Tenga en cuenta que el cambio principal que he hecho aquí desde el código en su pregunta es el uso de getActivity() para obtener la referencia de actividad necesaria para la llamada a startResolutionForResult() .

case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
try {
fragment.startIntentSenderForResult(status.getResolution().getIntentSender(), REQUEST_CHECK_SETTINGS, null, 0, 0, 0, null);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;

Aquí están los resultados visualmente, primero se muestra el cuadro de diálogo si el Modo de ubicación está desactivado:

Luego, si el usuario hace clic en No, el resultado se pasa de la Actividad al Fragmento, que muestra un Brindis:

Lo mismo cuando el usuario hace clic en Sí, pero con un resultado exitoso y el Modo de ubicación está habilitado:

Tenga en cuenta que podría ser una mejor opción simplemente mantener toda esta funcionalidad en la Actividad, y luego llamar a un método público en el Fragmento cuando llegue el resultado.

Aquí hay un código completamente funcional para mantener la funcionalidad en la Actividad. Por supuesto, en esta solución, deberá agregar una llamada al Fragmento para actualizar el estado del Modo de ubicación después de que se onActivityResult() .

startIntentSenderForResult(status.getResolution().getIntentSender(), REQUEST_CODE_LOCATION_SETTING, null, 0, 0, 0, null);
