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"
}
}

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);
}
}
}
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。
城市和国家不总是在地址1号线和2号线…
例子在这里
So,
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude,longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String zip = addresses.get(0).getPostalCode();
String country = addresses.get(0).getCountryName();
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;
}
}
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(",", "") + ", ";
}
}
