我想从纬度和经度在安卓得到以下值

街道地址 城市/州 邮政编码 完整的地址

如何做到这一点?

你可以创建类

public class GeoLocation {

private Context mContext;

private String mLatitude;
private String mLongtitude;
private String mStreet;
private String mHouseNumber;
private String mPostalCode;
private String mCity;

private Location mMarkerLocation;

public GeoLocation (Context context) {
    mContext = context;
}

public String getStreet () {
    return mStreet;
}

public String getHouseNumber () {
    return mHouseNumber;
}

public String getPostalCode () {
    return mPostalCode;
}

public String getCity () {
    return mCity;
}

public String getLatitude () {
    return mLatitude;
}

public String getLongtitude () {
    return mLongtitude;
}

// Lookup address via reverse geolocation
// Call this one
public void lookUpAddress (Location markerLocation) {
    mMarkerLocation = markerLocation;
    if (Geocoder.isPresent()) {
        (new GetAddressTask(mContext)).execute();
    }
}

public class GetAddressTask extends AsyncTask<android.location.Location, Void, String> {

    public GetAddressTask (Context context) {
        super();
        mContext = context;
    }

    @Override
    protected String doInBackground (android.location.Location... params) {
        Geocoder geocoder =
                new Geocoder(mContext, Locale.getDefault());
        android.location.Location location = params[0];

        List<Address> addresses = null;
        try {
            if (mMarkerLocation != null) {
                addresses = geocoder.getFromLocation(mMarkerLocation.getLatitude(),
                        mMarkerLocation.getLongitude(), 1);
            }
        } catch (IOException exception) {
            Log.e("ComplaintLocation",
                    "IO Exception in getFromLocation()", exception);

            return ("IO Exception trying to get address");
        } catch (IllegalArgumentException exception) {
            String errorString = "Illegal arguments " +
                    Double.toString(location.getLatitude()) + " , " +
                    Double.toString(location.getLongitude()) + " passed to address service";
            Log.e("LocationSampleActivity", errorString, exception);

            return errorString;
        }

        if (addresses != null && addresses.size() > 0) {
            Address address = addresses.get(0);

            if (address.getMaxAddressLineIndex() > 0) {
                return String.format(
                        "%s/%s/%s/%s/%s/%s",
                        address.getLatitude(), // 0
                        address.getLongitude(), // 1
                        address.getThoroughfare(), // 2
                        address.getSubThoroughfare(), //3
                        address.getPostalCode(), // 4
                        address.getLocality()); // 5
            } else {
                return String.format(
                        "%s/%s/%s/%s",
                        address.getLatitude(), // 0
                        address.getLongitude(), // 1
                        address.getPostalCode(), // 2
                        address.getLocality()); // 3
            }
        } else return "No address found";
    }

    // Format address string after lookup
    @Override
    protected void onPostExecute (String address) {

        String[] addressFields = TextUtils.split(address, "/");
        Log.d("ADDRESS ARRAY", Arrays.toString(addressFields));

        // Workaround: doInBackground can only return Strings instead of, for example, an
        // Address instance or a String[] directly. To be able to use TextUtils.isEmpty()
        // on fields returned by this method, set each String that currently reads "null" to
        // a null reference
        for (int fieldcnt = 0; fieldcnt < addressFields.length; ++fieldcnt) {
            if (addressFields[fieldcnt].equals("null"))
                addressFields[fieldcnt] = null;
        }

        switch (addressFields.length) {
            case 4:
                mStreet = null;
                mHouseNumber = null;
                mLatitude = addressFields[0];
                mLongtitude = addressFields[1];
                mPostalCode = addressFields[2];
                mCity = addressFields[3];
                break;
            case 6:
                mLatitude = addressFields[0];
                mLongtitude = addressFields[1];
                mStreet = addressFields[2];
                mHouseNumber = addressFields[3];
                mPostalCode = addressFields[4];
                mCity = addressFields[5];
                break;
            default:
                mLatitude = null;
                mLongtitude = null;
                mStreet = null;
                mHouseNumber = null;
                mPostalCode = null;
                mCity = null;
                break;
        }

        Log.d("GeoLocation Street", mStreet);
        Log.d("GeoLocation No.", mHouseNumber);
        Log.d("GeoLocation Postalcode", mPostalCode);
        Log.d("GeoLocation Locality", mCity);
        Log.d("GeoLocation Lat/Lng", "[" + mLatitude + ", " + mLongtitude + 
    "]");
    }
 }
   }

然后使用

GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if 
called from an activity and not from a fragment
mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);

其他回答

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);
        }
    }
}

在onCreate () . .

LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 0, this);
    Criteria criteria = new Criteria();
    String bestProvider = locationManager.getBestProvider(criteria, true);
    Location location = locationManager.getLastKnownLocation(bestProvider);

    if (location == null) {
        Toast.makeText(getApplicationContext(), "GPS signal not found",
                3000).show();
    }
    if (location != null) {
        Log.e("location", "location--" + location);
        Log.e("latitude at beginning",
                "@@@@@@@@@@@@@@@" + location.getLatitude());
        onLocationChanged(location);
    }

在onLocationChanged()中编写代码

@Override
public void onLocationChanged(Location location) {

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

    latitude = location.getLatitude();
    longitude = location.getLongitude();

    Log.e("latitude", "latitude--" + latitude);

    try {
        Log.e("latitude", "inside latitude--" + latitude);
        addresses = geocoder.getFromLocation(latitude, longitude, 1);

        if (addresses != null && addresses.size() > 0) {
            String address = addresses.get(0).getAddressLine(0); 
            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(); 

            locationTxt.setText(address + " " + city + " " + country);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

接受的答案在kotlin格式

private fun getAddressInfo(latitude:Double, longitude:Double){
    val geocoder = Geocoder(this, Locale.getDefault())
    val addresses: List<Address> = geocoder.getFromLocation(latitude, longitude, 1)

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

使用地理编码器,你可以得到这样的东西!

           try {
                Geocoder geo = new Geocoder(MapsActivity.this.getApplicationContext(), Locale.getDefault());
                List<Address> addresses = geo.getFromLocation(origin.latitude, origin.longitude, 1);
                address.setText("Loading...");
                if (addresses != null && addresses.size() > 0) {
                    String locality = addresses.get(0).getAddressLine(0);
                    String country = addresses.get(0).getCountryName();
                    String state = addresses.get(0).getAdminArea();
                    String sub_admin = addresses.get(0).getSubAdminArea();
                    String city = addresses.get(0).getFeatureName();
                    String pincode = addresses.get(0).getPostalCode();
                    String locality_city = addresses.get(0).getLocality();
                    String sub_localoty = addresses.get(0).getSubLocality();
                    if (locality != null && country != null) {
                        address.setText(locality + ", " + (sub_localoty != null ? sub_localoty + ", " : "")  + (locality_city != null ? locality_city + ", " : "" ) + (city != null ? city + ", " : "")  + (sub_admin != null ? sub_admin + ", " : "") + (state != null ? state + ", " : "") + country + ", " + (pincode != null ? pincode : ""));
                    } else {
                        address.setText("Location could not be fetched...");
                    }
                }
            } catch (Exception e) {
                address.setText("Location could not be fetched...");
                e.printStackTrace(); // getFromLocation() may sometimes fail
            }
  public static String getAddressFromLatLng(Context context, LatLng latLng) {
    Geocoder geocoder;
    List<Address> addresses;
    geocoder = new Geocoder(context, Locale.getDefault());
    try {
        addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
        return addresses.get(0).getAddressLine(0);
    } catch (Exception e) {
        e.printStackTrace();
        return "";
    }
}
