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。

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);
        }
    }
}

你可以这样做，以获得完整的经纬度地址:

  public class MainActivity extends AppCompatActivity {

         ...

  private Geocoder geocoder;
  private TextView mAddressTxtVu;

         ...


  // I assume that you got latitude and longitude correctly 

  mLatitude  =  20.23232
  mLongitude =  32.999

  String errorMessage = "";

  geocoder = new Geocoder(context, Locale.getDefault());

  List<Address> addresses = null;

  try {
              addresses = geocoder.getFromLocation(
                       mlattitude,
                       mlongitude,
                       1);
      } catch (IOException e) {
              errorMessage = getString(R.string.service_not_available);
              Log.e(TAG, errorMessage, e);
      } catch (IllegalArgumentException illegalArgumentException) {
                        // Catch invalid latitude or longitude values.
              errorMessage = getString(R.string.invalid_lat_long_used);
              Log.e(TAG, errorMessage + ". " + "Latitude = " + mlattitude +", Longitude = " + mlongitude, illegalArgumentException);
      }

      // Handle case where no address was found.
      if (addresses == null || addresses.size() == 0) {
             if (errorMessage.isEmpty()) {
                      errorMessage = getString(R.string.no_address_found);
                      Log.e(TAG, errorMessage);
             }

      } else {
             Address address = addresses.get(0);
             ArrayList<String> addressFragments = new ArrayList<String>();

             // Fetch the address lines using getAddressLine,
             // join them, and send them to the thread.
             for (int i = 0; i <= address.getMaxAddressLineIndex(); i++) {
                      addressFragments.add(address.getAddressLine(i));
             }
             // Log.i(TAG, getString(R.string.address_found));


    mAddressTxtVu.setText(TextUtils.join(System.getProperty("line.separator"),
                                addressFragments));
                    }

如果您使用Kotlin语言，我创建这个方法来直接获取地址位置

private fun getAddress(latLng: LatLng): String {
    val geocoder = Geocoder(this, Locale.getDefault())
    val addresses: List<Address>?
    val address: Address?
    var addressText = ""

    addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1)

    if (addresses.isNotEmpty()) {
        address = addresses[0]
        addressText = address.getAddressLine(0)
    } else{
        addressText = "its not appear"
    }
    return addressText
}

但是当你调用这个方法时，这个方法只返回String值

如果你想获取所有地址，你只需使用这个方法/函数

fun getAddress(latLng: LatLng){
    val geocoder = Geocoder(this, Locale.getDefault())
    val addresses: List<Address>?
    val address: Address?
    var fulladdress = ""
    addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1)

    if (addresses.isNotEmpty()) {
        address = addresses[0]
        fulladdress = address.getAddressLine(0) // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex
        var city = address.getLocality();
        var state = address.getAdminArea();
        var country = address.getCountryName();
        var postalCode = address.getPostalCode();
        var knownName = address.getFeatureName(); // Only if available else return NULL
    } else{
        fulladdress = "Location not found"
    }
}

public String getAddress(LatLng latLng) {
    String cAddress = "";
    if (latLng == null) {
        errorMessage = "no_location_data_provided";
        Log.wtf(TAG, errorMessage);
        return "";
    }
    Geocoder geocoder = new Geocoder(this, Locale.getDefault());

    // Address found using the Geocoder.
    List<Address> addresses = null;

    try {
        // Using getFromLocation() returns an array of Addresses for the area immediately
        // surrounding the given latitude and longitude. The results are a best guess and are
        // not guaranteed to be accurate.
        addresses = geocoder.getFromLocation(
                latLng.latitude,
                latLng.longitude,
                // In this sample, we get just a single address.
                1);
    } catch (IOException ioException) {
        // Catch network or other I/O problems.
        errorMessage = "service_not_available";
        Log.e(TAG, errorMessage, ioException);
    } catch (IllegalArgumentException illegalArgumentException) {
        // Catch invalid latitude or longitude values.
        errorMessage = "invalid_lat_long_used";
        Log.e(TAG, errorMessage + ". " +
                "Latitude = " + latLng.latitude +
                ", Longitude = " + latLng.longitude, illegalArgumentException);
    }

    // Handle case where no address was found.
    if (addresses == null || addresses.size() == 0) {
        if (errorMessage.isEmpty()) {
            errorMessage = "no_address_found";
            Log.e(TAG, errorMessage);
        }
    } else {
        Address address = addresses.get(0);
        ArrayList<String> addressFragments = new ArrayList<String>();
        // Fetch the address lines using {@code getAddressLine},
        // join them, and send them to the thread. The {@link android.location.address}
        // class provides other options for fetching address details that you may prefer
        // to use. Here are some examples:
        // getLocality() ("Mountain View", for example)
        // getAdminArea() ("CA", for example)
        // getPostalCode() ("94043", for example)
        // getCountryCode() ("US", for example)
        // getCountryName() ("United States", for example)
        String allAddress = "";
        for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
            addressFragments.add(address.getAddressLine(i));
            allAddress += address.getAddressLine(i) + " ";
        }
        if (address.getAdminArea() != null) {
            state = address.getAdminArea();
        } else {
            state = "";
        }
        if (address.getLocality() != null) {
            city = address.getLocality();
        } else {
            city = "";
        }
        if (address.getPostalCode() != null) {
            postalCode = address.getPostalCode();
        } else {
            postalCode = "";
        }

        Log.i(TAG, "address_found");
        //driverAddress = TextUtils.join(System.getProperty("line.separator"), addressFragments);
        cAddress = allAddress;
        Log.e("result", cAddress.toString());
    }
    return cAddress;
}

您可以使用此方法对正确完整的地址进行地理编码

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;

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

        // Workaround: doInBackground can only return Strings instead of, for example, an

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

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);
