试试这段代码(正在工作)

public void GetLocation() throws IOException {

    LocationManager locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);

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

        ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION
        }, 200);

        return;
    } else {



        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 0, new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                Log.d(TAG, "onLocationChanged: " + location.getLongitude() + " , " + location.getLatitude());

            }

            @Override
            public void onStatusChanged(String s, int i, Bundle bundle) {
                Log.d(TAG, "onStatusChanged: " + s);

            }

            @Override
            public void onProviderEnabled(String s) {

            }

            @Override
            public void onProviderDisabled(String s) {

            }
        });
        Criteria criteria = new Criteria();
        String bestProvider = locationManager.getBestProvider(criteria, true);
        Location location = locationManager.getLastKnownLocation(bestProvider);

        if (location == null) {
            Toast.makeText(context, "GPS signal not found",
                    Toast.LENGTH_LONG).show();
        }
        if (location != null) {
            Log.e("location", "location--" + location);
            Log.e("latitude at beginning",
                    "@@@@@@@@@@@@@@@" + location.getLatitude());
            // onLocationChanged(location);
        }


        Geocoder geocoder;
        List<Address> addresses;
        geocoder = new Geocoder(context, Locale.getDefault());
        addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
        String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
        String city = addresses.get(0).getLocality();
        String state = addresses.get(0).getAdminArea();
        String country = addresses.get(0).getCountryName();
        String postalCode = addresses.get(0).getPostalCode();
        String knownName = addresses.get(0).getFeatureName();

        Log.d(TAG, "GetLocation: address " + address + " city " + city + " state " + state + " country " + country + " postalCode " + postalCode + " knownName " + knownName);
    }
}

尝试使用geocoder使用下面的代码:

  Geocoder gcd = new Geocoder(MainActivity.this, Locale.getDefault());
  List<Address> geoAddresses = geoAddresses = gcd.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
  if (geoAddresses.size() > 0) {
      String mUserLocation = "";
      for (int i = 0; i < 4; i++) { //Since it return only four value we declare this as static.
           mUserLocation = mUserLocation + geoAddresses.get(0).getAddressLine(i).replace(",", "") + ", ";
        } 
    }

似乎还没有人提供谷歌Docs (https://developer.android.com/training/location/display-address#java)建议的解决方案。正确的解决方案应该使用IntentService进行反向地理编码的网络调用。

使用意图服务而不是AsyncTask，因为它没有绑定到任何特定的活动。ie。它有自己的生命周期。当地理编码完成时，IntentService将自动停止。

public class GeocodingService extends IntentService {

    public GeocodingService() {
        super("GeocodingService");
    }


    @Override
    protected void onHandleIntent(@Nullable Intent intent) {
        if (intent == null) {
            return;
        }

        Geocoder geocoder = new Geocoder(this, Locale.getDefault());
        String errorMessage = "";
        BCCDatabase BCCDatabase = skicompanion.skicompanion.storage.BCCDatabase.getInstance(getApplicationContext());

        // Get the location passed to this service through an extra.
        Location location = intent.getParcelableExtra(
                "location");
        long trackID = intent.getLongExtra("trackID", -1);

        List<Address> addresses = null;
        String addressString = "";

        try {
            addresses = geocoder.getFromLocation(
                    location.getLatitude(),
                    location.getLongitude(),
                    1);
        } catch (IOException ioException) {
            // Catch network or other I/O problems.
            errorMessage = "service not available";
            Log.d(Constants.SkiCompanionDebug, errorMessage, ioException);
        } catch (IllegalArgumentException illegalArgumentException) {
            // Catch invalid latitude or longitude values.
            errorMessage = "invalid lat long used";
            Log.d(Constants.SkiCompanionDebug, errorMessage + ". " +
                    "Latitude = " + location.getLatitude() +
                    ", Longitude = " +
                    location.getLongitude(), illegalArgumentException);
        }

        // Handle case where no address was found.
        if (addresses == null || addresses.size()  == 0) {
            if (errorMessage.isEmpty()) {
                errorMessage = "no address found";
                Log.d(Constants.SkiCompanionDebug, errorMessage);
            }
        } else {
            if(addresses.get(0).getLocality() != null){
                addressString += addresses.get(0).getLocality() + ", ";
            }
            if(addresses.get(0).getAdminArea() != null){
                addressString += addresses.get(0).getAdminArea() + ", ";
            }
            if(addresses.get(0).getCountryName() != null){
                addressString += addresses.get(0).getCountryName();
            }
            //updating DB
            BCCDatabase.setTrackLocation(trackID, addressString);

            Log.d(Constants.SkiCompanionDebug, "address found: "+ addressString);
        }
    }
}

使用Geocoder类从纬度和经度中获得完整地址非常容易。下面是代码示例。希望这能有所帮助!

 if (l != null) {
        val lat = l.latitude
        val lon = l.longitude

        val geocoder = Geocoder(this, Locale.getDefault())
        val addresses: List<Address>

        addresses = geocoder.getFromLocation(lat, lon, 1) 

        val address = addresses[0].getAddressLine(0)
        val address2 = addresses[0].getAddressLine(1)
        val city = addresses[0].locality
        val state = addresses[0].adminArea
        val country = addresses[0].countryName
        val postalCode = addresses[0].postalCode
        val knownName = addresses[0].featureName

        val message =
                "Emergency situation. Call for help. My location is: " + address + "." + "http://maps.google.com/maps?saddr=" + lat + "," + lon

    }

您可以只使用地址值，因为它提供了所有完整的地址。如果需要单独的组件，也可以使用其他组件。

您需要传递纬度和经度值。

Geocoder geocoder;
        List<Address> addresses;
        geocoder = new Geocoder(getContext(), Locale.getDefault());

        try {
            addresses = geocoder. getFromLocation(latitude, longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
            String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
            String city = addresses.get(0).getLocality();
            String state = addresses.get(0).getAdminArea();
            String country = addresses.get(0).getCountryName();
            String postalCode = addresses.get(0).getPostalCode();
            String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL

            System.out.println(address+"-------------");
        } catch (IOException e) {
            e.printStackTrace();
        }

  Geocoder geocoder =new Geocoder(mContext, Locale.getDefault());
 // Get the current location from the input parameter list
  Location loc = params[0];
 // Create a list to contain the result address
  List<Address> addresses = null;
  try {
     addresses = geocoder.getFromLocation(loc.getLatitude(),
             loc.getLongitude(), 10);
 } catch (IOException e1) {
           Log.e("LocationSampleActivity","IO Exception in getFromLocation()");
      e1.printStackTrace();

 } catch (IllegalArgumentException e2) {
 // Error message to post in the log
 String errorString = "Illegal arguments " +
         Double.toString(loc.getLatitude()) +
         " , " +
         Double.toString(loc.getLongitude()) +
         " passed to address service";
 Log.e("LocationSampleActivity", errorString);
 e2.printStackTrace();

 }
 Address address=null;
 String zip=null;
 String city=null;
 String state=null;
 StringBuffer st=new StringBuffer();
 // If the reverse geocode returned an address
 if (addresses != null && addresses.size() > 0) {

  for(int i=0 ;i<addresses.size();i++){

   if(address.getPostalCode()!=null){
zip=address.getPostalCode();
break;
     }

      }
