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?


当前回答

1 -在onCreate方法中为LocationManager和LocationListener创建变量。

2 -检查是否有权限,因此执行位置更新并从locationManager获取lastKnownLocation,否则您将请求权限

3 -在主类中创建onRequestPermissionResult并检查是否有权限,然后执行位置更新

4 -创建分离的方法,其中包括Geocoder变量,并创建一个列表,从您的位置放置坐标, 所以为了安全起见,你检查列表是否存在,如果我们想在该列表中的每个信息是存在的,那么你使用(get通道==>街道地址),(getLocality ==>城市/州),(getPostalCode ==> Zip), (getAdminArea ==>完整地址)

5 -最后,在检查权限后调用该方法(lastKnownLocation参数==>,当应用程序运行时显示地址)和onLocationChanged with(位置参数==>,当位置改变时显示地址)

代码部分:

LocationManager locationManager;

LocationListener locationListener;

@SuppressLint("MissingPermission")
@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    locationManager  = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    locationListener = new LocationListener() {

        @Override
        public void onLocationChanged(Location location) {

            updateLocation(location);

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

        }
        @Override
        public void onProviderEnabled(String provider) {
        }
        @Override
        public void onProviderDisabled(String provider) {
        }
    };

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){

        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

        Location lastKnownLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

        updateLocation(lastKnownLocation);

    }else {

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

@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);
        }
    }
}


public void updateLocation ( Location location){


    Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
    try {
        List<Address> listAddresses = geocoder.getFromLocation(location.getLatitude(),location.getLongitude(),1);

        String address = "Could not find location :(";

        if (listAddresses != null && listAddresses.size() > 0) {

            if (listAddresses.get(0).getThoroughfare() != null) {

                address = listAddresses.get(0).getThoroughfare() + " ";
            }

            if (listAddresses.get(0).getLocality() != null) {

                address += listAddresses.get(0).getLocality() + " ";
            }

            if (listAddresses.get(0).getPostalCode() != null) {

                address += listAddresses.get(0).getPostalCode() + " ";
            }

            if (listAddresses.get(0).getAdminArea() != null) {

                address += listAddresses.get(0).getAdminArea();
            }
        }

        Log.i("Address",address);

    } catch (Exception e) {

        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);

要做更多,你应该在这里阅读Geocoder。

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

从latlong (Geo-coordinates)获取Address还有最后一个技巧。你可以简单地通过经度和纬度点击谷歌地图web服务。它只是一个GET-Method web服务。

它将返回JSON响应,可以很容易地解析以获得地址。它的URL是:

http://maps.googleapis.com/maps/api/geocode/json?latlng=32,75&sensor=true

你可以用lat,long代替32,75。

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.

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