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?

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
}

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) {

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。
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(",", "") + ", ";
}
}
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"
}
}
