我的设备上GPS位置错误

Question

I'm trying to get my device location and add a marker on a Google Map. If I start my application on the virtual device it shows me in the log an unusual location in the USA (but I live in Italy) but not the Map and the marker and when I start my application on my physical device it doesn't found the location but I can see on the map a marker in the coordinates 0 latitude and 0 longitude.

Here is my MainActivity:

public class MainActivity extends AppCompatActivity {

    private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPager viewPager;
    private LocationManager locationManager;
    private LocationListener locationListener;
    private double latitudine;
    private double longitudine;


    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        locationManager = (LocationManager) this.getSystemService(LOCATION_SERVICE);
        locationListener = new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                Log.d("Location: ", location.toString());
                latitudine = location.getLatitude();
                longitudine = location.getLongitude();
            }

            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {

            }

            @Override
            public void onProviderEnabled(String provider) {

            }

            @Override
            public void onProviderDisabled(String provider) {

            }
        };

        if (Build.VERSION.SDK_INT < 23) {

            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                // TODO: Consider calling
                //    ActivityCompat#requestPermissions
                // here to request the missing permissions, and then overriding
                //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                //                                          int[] grantResults)
                // to handle the case where the user grants the permission. See the documentation
                // for ActivityCompat#requestPermissions for more details.
                return;
            }
            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

        }else{

            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

                ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION},1);

            }else{
                locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
            }

        }

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        getSupportActionBar().setDisplayHomeAsUpEnabled(false);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        tabLayout.getTabAt(0).setIcon(R.drawable.drone);
        tabLayout.getTabAt(1).setIcon(R.drawable.maps);
        tabLayout.getTabAt(2).setIcon(R.drawable.registracion);
        tabLayout.getTabAt(3).setIcon(R.drawable.meteo);
        tabLayout.getTabAt(4).setIcon(R.drawable.user);

    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(grantResults.length>0 && grantResults[0]== PackageManager.PERMISSION_GRANTED){
            if(ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION)==PackageManager.PERMISSION_GRANTED){
                locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
            }
        }
    }

    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFragment(new FirstFragment(), "");
        adapter.addFragment(new SecondFragment(latitudine,longitudine), "");
        adapter.addFragment(new ThirdFragment(), "");
        adapter.addFragment(new FourthFragment(), "");
        adapter.addFragment(new FifthFragment(), "");
        viewPager.setAdapter(adapter);
    }

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFragment(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
}

That's SecondFragment and is the fragment where should be the map:

public class SecondFragment extends Fragment implements OnMapReadyCallback {

    private GoogleMap mGoogleMap;
    private MapView mMapView;
    private View mView;
    private LatLng position;

    public SecondFragment() {
    }

    @SuppressLint("ValidFragment")
    public SecondFragment(double lat, double lon){
        position = new LatLng(lat,lon);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        mView = inflater.inflate(R.layout.fragment_second, container, false);
        return mView;
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        mMapView = (MapView) mView.findViewById(R.id.mapGoogle);
        if (mMapView != null) {
            mMapView.onCreate(null);
            mMapView.onResume();
            mMapView.getMapAsync(this);
        }
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        MapsInitializer.initialize(getContext());
        mGoogleMap = googleMap;
        googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        googleMap.addMarker(new MarkerOptions().position(position));
    }
}

That's the run when I launch my application on my physical device:

Answer 1

try use this code :

don't forget to add permissions in manifest file

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

implement your class with :

implements LocationListener, GoogleApiClient.ConnectionCallbacks, ResultCallback, GoogleApiClient.OnConnectionFailedListener

protected GoogleApiClient mGoogleApiClient;
protected LocationRequest locationRequest;

String latitude = "";
String longitude = "";

@Override
public void onCreate(Bundle savedInstanceState) {


  if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return rootView;
    }
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).build();
    mGoogleApiClient.connect();
    locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(30 * 1000);
    locationRequest.setFastestInterval(5 * 1000);

    LocationManager locationManager = (LocationManager) getActivity()
            .getSystemService(Context.LOCATION_SERVICE);
    Criteria locationCritera = new Criteria();
    String providerName = locationManager.getBestProvider(locationCritera,
            true);
    if (providerName != null) {
        try {
            Location location = locationManager.getLastKnownLocation(providerName);
            latitude = location.getLatitude() + "";
            longitude = location.getLongitude() + "";
        } catch (Exception e) {
            latitude = "0";
            longitude = "0";
        }
    }


    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
            0, NearByFragment.this);


     }






@Override
public void onLocationChanged(Location location) {

    latitude = String.valueOf(location.getLatitude());

}

                    mGoogleApiClient,
                    builder.build()
            );

    result.setResultCallback(this);
}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}

@Override
public void onResult(@NonNull LocationSettingsResult locationSettingsResult) {
    final Status status = locationSettingsResult.getStatus();
    switch (status.getStatusCode()) {
        case LocationSettingsStatusCodes.SUCCESS:

            // NO need to show the dialog;

            break;

                // Show the dialog by calling startResolutionForResult(), and check the result
                // in onActivityResult().

                status.startResolutionForResult(getActivity(), 100);

            } catch (Exception e) {
