Получить текущее местоположение с помощью объединенного провайдера местоположения
У меня есть эта активность, и я хочу получить текущее местоположение, но пока не знаю, как правильно ее завершить. Кроме того, что такое REQUEST_CODE_ASK_PERMISSIONS?? я должен генерировать один?
public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
private double longitude;
private double latitude;
private TextView latitudeText, longitudeText;
private FusedLocationProviderClient fusedLocationProviderClient;
private GoogleApiClient googleApiClient;
private LocationManager locationManager;
private LocationListener locationListener;
private LocationRequest locationRequest;
private LocationCallback locationCallback;
final private int REQUEST_CODE_ASK_PERMISSIONS = 123;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
latitudeText = findViewById(R.id.latitudeText);
longitudeText = findViewById(R.id.longitudeText);
getLocation();
}
private void getLocation() {
locationRequest = new LocationRequest()
.setInterval(2000).setFastestInterval(2000).setPriority(1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
SettingsClient client = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
locationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
for (Location location : locationResult.getLocations()) {
latitude = location.getLatitude();
longitude = location.getLongitude();
latitudeText.setText(String.valueOf(latitude));
longitudeText.setText(String.valueOf(longitude));
}
}
};
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
@Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
}
});
}
@Override
protected void onResume() {
super.onResume();
if (ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest
.permission.ACCESS_FINE_LOCATION},REQUEST_CODE_ASK_PERMISSIONS);
} else if(){
}
}
@Override
public void onConnected(@Nullable Bundle bundle) {
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}

ПРИМЕЧАНИЕ. Предоставьте разрешения для устройств "Зефир" и "Над версией".
Ответ Кетана Рамани помог мне и всем кредитам ему. Я сделал небольшую корректировку, чтобы можно было устанавливать количество обновлений, особенно если требуется только одно.

Настройка местоположения Provider
locationProvider = new LocationProvider.Builder(MainActivity.this)
.setInterval(10000)
.setFastestInterval(5000)
.setNumberOfUpdates(1) // If you want infinite updates, remove this line entirely
.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY)

Вы должны переопределить onRequestPermissionsResult
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_PERMISSIONS: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
getLocation();
}
}
}
}
Так что вам решать REQUEST_CODE_ASK_PERMISSIONS и его роль заключается в обработке обратного вызова, особенно если вы запрашиваете больше, чем на разрешение.
И я думаю, что ваш getLocation() использует устаревший API. Посмотрите здесь, как получить местоположение.
Попробуйте описанный ниже способ получить местоположение с помощью FusedLocationProviderClient.
public class LocationTrackerClient{
public static String TAG = LocationTrackerClient.class.getName();
private Location mLastLocation;
LocationRequest mLocationRequest;
private FusedLocationProviderClient mFusedLocationClient;
static Context mcontext;
private static int UPDATE_INTERVAL = 1000;
private static int FATEST_INTERVAL = 1000;
private static int DISPLACEMENT = 5;
private static LocationTrackerClient instance;
private boolean isConnected = false;
public static synchronized LocationTrackerClient getInstance(Context ctx) {
mcontext = ctx;
if (instance == null) {
instance = new LocationTrackerClient();
}
return instance;
}
public void getLocationclient() {
try {
mFusedLocationClient = null;
mFusedLocationClient = LocationServices.getFusedLocationProviderClient(mcontext);
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
mLocationRequest.setInterval(UPDATE_INTERVAL);
mLocationRequest.setFastestInterval(FATEST_INTERVAL);
mLocationRequest.setSmallestDisplacement(DISPLACEMENT);
} catch (Exception e) {
ExceptionHandler.printStackTrace(e);
}
}
public void connectToLocation() {
stopLocationUpdates();
getLocationclient();
displayLocation();
}
public void stopLocationUpdates() {
removeFusedLocationUpdate();
}
public void removeFusedLocationUpdate() {
if (Build.VERSION.SDK_INT >= 23) {
if (ContextCompat.checkSelfPermission(mcontext,Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(mcontext, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
}else{
return;
}
}
try {
if (mFusedLocationClient != null) {
mFusedLocationClient
.removeLocationUpdates(mLocationCallback)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
Logger.d(TAG, "Location updates stopped at removeFusedLocationUpdate! == ");
// Toast.makeText(getApplicationContext(), "Location updates stopped!", Toast.LENGTH_SHORT).show();
}
});
}
} catch (Exception e) {
e.printStackTrace();
}
}
private void displayLocation() {
try {
mFusedLocationClient.requestLocationUpdates(mLocationRequest,
mLocationCallback, Looper.myLooper());
} catch (SecurityException e) {
ExceptionHandler.printStackTrace(e);
} catch (Exception e) {
ExceptionHandler.printStackTrace(e);
}
}
private LocationCallback mLocationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
super.onLocationResult(locationResult);
Logger.e(TAG, "locationResult ==== " + locationResult);
if (locationResult != null) {
mLastLocation = locationResult.getLastLocation();
if (mLastLocation != null) {
double latitude = mLastLocation.getLatitude();
double longitude = mLastLocation.getLongitude();
updateLattitudeLongitude(latitude, longitude);
}
}
}
};
public void updateLattitudeLongitude(double latitude, double longitude) {
Logger.i(TAG, "updated Lat == " + latitude + " updated long == " + longitude);
SharedPreferenceManager sharedPreferenceManager = SharedPreferenceManager.getInstance();
sharedPreferenceManager.updateUserDeviceLatLong(latitude, longitude);
}
}
На всякий случай, если кто-то найдет для этого решение. Теперь вы можете использовать FusedLocationClient.getCurrentLocation в версии библиотеки play-services-location
17.1.0
