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

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。

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。

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);
        }
    }
}

您可以使用此方法对正确完整的地址进行地理编码

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
}
