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(",", "") + ", ";
        } 
    }

  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) {
 String       add=addresses.get(0).getAddressLine(0)+","
  +addresses.get(0).getSubAdminArea()+","
  +addresses.get(0).getSubLocality();
  city=addresses.get(0).getLocality();
  state=addresses.get(0).getAdminArea();
     // Get the first address
  for(int i=0 ;i<addresses.size();i++){
  address = addresses.get(i);
   if(address.getPostalCode()!=null){
zip=address.getPostalCode();
break;
     }

      }

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

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

要了解更多可用细节，请查看Android-Location-Address

  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 "";
    }
}

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();
    }
}

您正在寻找“地理编码”一词。

你需要做的是:

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
