Jak sprawdzić, czy usługi lokalizacji są włączone?
Rozwijam aplikację na Android OS. Nie wiem, jak sprawdzić, czy usługi lokalizacji są włączone, czy nie.
Potrzebuję metody, która zwraca "true", jeśli są włączone i "false", jeśli nie (więc w ostatnim przypadku mogę pokazać okno, aby je włączyć).

Możesz użyć poniższego kodu, aby sprawdzić, czy dostawca gps i dostawcy sieci są włączone, czy nie.
LocationManager lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
boolean gps_enabled = false;
boolean network_enabled = false;
try {
gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch(Exception ex) {}
try {
network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch(Exception ex) {}
if(!gps_enabled && !network_enabled) {
// notify user
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
dialog.setMessage(context.getResources().getString(R.string.gps_network_not_enabled));
dialog.setPositiveButton(context.getResources().getString(R.string.open_location_settings), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
// TODO Auto-generated method stub
Intent myIntent = new Intent( Settings.ACTION_LOCATION_SOURCE_SETTINGS);
context.startActivity(myIntent);
//get gps
}
});
dialog.setNegativeButton(context.getString(R.string.Cancel), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
// TODO Auto-generated method stub
}
});
dialog.show();
}
I w pliku manifest, musisz dodać następujące uprawnienia
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Używam tego kodu do sprawdzania:
public static boolean isLocationEnabled(Context context) {
int locationMode = 0;
String locationProviders;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
try {
locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
} catch (SettingNotFoundException e) {
e.printStackTrace();
return false;
}
return locationMode != Settings.Secure.LOCATION_MODE_OFF;
}else{
locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
return !TextUtils.isEmpty(locationProviders);
}
}

Możesz użyć tego kodu, aby skierować użytkowników do ustawień, gdzie mogą włączyć GPS:
locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
if( !locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) ) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(R.string.gps_not_found_title); // GPS not found
builder.setMessage(R.string.gps_not_found_message); // Want to enable?
builder.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
owner.startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
}
});
builder.setNegativeButton(R.string.no, null);
builder.create().show();
return;
}

Pracując nad powyższą odpowiedzią, w API 23 należy dodać" niebezpieczne " kontrole uprawnień, jak również sprawdzenie samego systemu:
public static boolean isLocationServicesAvailable(Context context) {
int locationMode = 0;
String locationProviders;
boolean isAvailable = false;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
try {
locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
} catch (Settings.SettingNotFoundException e) {
e.printStackTrace();
}
isAvailable = (locationMode != Settings.Secure.LOCATION_MODE_OFF);
} else {
locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
isAvailable = !TextUtils.isEmpty(locationProviders);
}
boolean coarsePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED);
boolean finePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
return isAvailable && (coarsePermissionCheck || finePermissionCheck);
}

Tak możesz sprawdzić poniżej jest kod:
public boolean isGPSEnabled(Context mContext)
{
LocationManager lm = (LocationManager)
mContext.getSystemService(Context.LOCATION_SERVICE);
return lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
Z uprawnieniem w pliku manifestu:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Jeśli żaden dostawca nie jest włączony," pasywny " jest najlepszym zwracanym dostawcą. Zobacz https://stackoverflow.com/a/4519414/621690
public boolean isLocationServiceEnabled() {
LocationManager lm = (LocationManager)
this.getSystemService(Context.LOCATION_SERVICE);
String provider = lm.getBestProvider(new Criteria(), true);
return (StringUtils.isNotBlank(provider) &&
!LocationManager.PASSIVE_PROVIDER.equals(provider));
}

Ta klauzula if Łatwo Sprawdza, czy usługi lokalizacyjne są dostępne moim zdaniem:
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if(!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) && !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
//All location services are disabled
}

Jak zauważył Peter McClennan, Google ma API, które działa bardzo dobrze z nowym dostawcą lokalizacji fused. Całkowicie wypracowany przykład jest na przykładowy kod Google na Github nie musisz kodować okna dialogowego użytkownika, aby poprosić go o zmianę ustawień, ponieważ odbywa się to automatycznie za pomocą API.

Używam takiego sposobu dla NETWORK_PROVIDER ale można dodać i dla GPS .
LocationManager locationManager;
In onCreate I put
isLocationEnabled();
if(!isLocationEnabled()) {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle(R.string.network_not_enabled)
.setMessage(R.string.open_location_settings)
.setPositiveButton(R.string.yes,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
}
})
.setNegativeButton(R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
I metoda sprawdzania
protected boolean isLocationEnabled(){
String le = Context.LOCATION_SERVICE;
locationManager = (LocationManager) getSystemService(le);
if(!locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
return false;
} else {
return true;
}
}

Jest to bardzo przydatna metoda, która zwraca " true
", Jeśli Location services
są włączone:
public static boolean locationServicesEnabled(Context context) {
LocationManager lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
boolean gps_enabled = false;
boolean net_enabled = false;
try {
gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch (Exception ex) {
Log.e(TAG,"Exception gps_enabled");
}
try {
net_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch (Exception ex) {
Log.e(TAG,"Exception network_enabled");
}
return gps_enabled || net_enabled;
}

Aby uzyskać aktualną lokalizację geograficzną W android Google maps, należy włączyć lokalizację urządzenia option.To sprawdź, czy lokalizacja jest włączona,czy nie, możesz w prosty sposób wywołać tę metodę ze swojej metody onCreate()
.
private void checkGPSStatus() {
LocationManager locationManager = null;
boolean gps_enabled = false;
boolean network_enabled = false;
if ( locationManager == null ) {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
}
try {
gps_enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch (Exception ex){}
try {
network_enabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch (Exception ex){}
if ( !gps_enabled && !network_enabled ){
AlertDialog.Builder dialog = new AlertDialog.Builder(MyActivity.this);
dialog.setMessage("GPS not enabled");
dialog.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//this will navigate user to the device location settings screen
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
});
AlertDialog alert = dialog.create();
alert.show();
}
}

Możesz zażądać aktualizacji lokalizacji i pokazać okno dialogowe razem, jak GoogleMaps doas również. Oto kod:
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 ignored) {}
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;
}
}
});
}
Jeśli potrzebujesz więcej informacji sprawdź klasę LocationRequest .

Dla Kotlina
private fun isLocationEnabled(mContext: Context): Boolean {
val lm = mContext.getSystemService(Context.LOCATION_SERVICE) as LocationManager
return lm.isProviderEnabled(LocationManager.GPS_PROVIDER) || lm.isProviderEnabled(
LocationManager.NETWORK_PROVIDER)
}
Dialog
private fun showLocationIsDisabledAlert() {
alert("We can't show your position because you generally disabled the location service for your device.") {
yesButton {
}
neutralPressed("Settings") {
startActivity(Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS))
}
}.show()
}
Zadzwoń tak
if (!isLocationEnabled(this.context)) {
showLocationIsDisabledAlert()
}
Podpowiedź: okno dialogowe wymaga następujących importów (android studio powinno zająć się tym za ciebie)
import org.jetbrains.anko.alert
import org.jetbrains.anko.noButton
I w manifeście potrzebujesz następujących uprawnień
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Aby sprawdzić, czy nie ma dostawcy sieci, wystarczy zmienić łańcuch przekazywany do Isproviderenabled na LocationManager.NETWORK_PROVIDER jeśli sprawdzisz wartości zwracane zarówno dla dostawcy GPS, jak i dostawcy sieci-oba false oznaczają brak usług lokalizacji

Używam pierwszego kodu begin create metoda isLocationEnabled
private LocationManager locationManager ;
protected boolean isLocationEnabled(){
String le = Context.LOCATION_SERVICE;
locationManager = (LocationManager) getSystemService(le);
if(!locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
return false;
} else {
return true;
}
}
I sprawdzam warunek czy ture otworzy mape i false da intent ACTION_LOCATION_SOURCE_SETTINGS
if (isLocationEnabled()) {
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
locationClient = getFusedLocationProviderClient(this);
locationClient.getLastLocation()
.addOnSuccessListener(new OnSuccessListener<Location>() {
@Override
public void onSuccess(Location location) {
// GPS location can be null if GPS is switched off
if (location != null) {
onLocationChanged(location);
Log.e("location", String.valueOf(location.getLongitude()));
}
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.e("MapDemoActivity", e.toString());
e.printStackTrace();
}
});
startLocationUpdates();
}
else {
new AlertDialog.Builder(this)
.setTitle("Please activate location")
.setMessage("Click ok to goto settings else exit.")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
