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
}

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);
}
}
}
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"
}
}
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));
}
只要用这个方法,把你的背,长。
public static void getAddress(Context context, double LATITUDE, double LONGITUDE{
//Set Address
try {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null && addresses.size() > 0) {
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
Log.d(TAG, "getAddress: address" + address);
Log.d(TAG, "getAddress: city" + city);
Log.d(TAG, "getAddress: state" + state);
Log.d(TAG, "getAddress: postalCode" + postalCode);
Log.d(TAG, "getAddress: knownName" + knownName);
}
} catch (IOException e) {
e.printStackTrace();
}
return;
}
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(",", "") + ", ";
}
}
