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?

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);
}
}
}

用这个对我有用:D
检索纬度和经度的json数据。
https://maps.googleapis.com/maps/api/geocode/json?key=AIzaSyAr29XeWWAeWZcrOgjjfs3iSnqkWtAz4No&latlng=2.1812,102.4266&sensor=true
用你自己的地方改变纬度、经度。
https://maps.googleapis.com/maps/api/geocode/json?key= < \ API_KEY_HERE > &latlng =“纬度,经度”&sensor = true
您可以使用自己的密钥更改<\API_KEY_HERE>。
需要在谷歌控制台为新的api密钥启用api服务。
D选项是正确答案
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;
}
}
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

试试这个，我的朋友
private String getCompleteAddressString(double LATITUDE, double LONGITUDE) {
String strAdd = "";
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder("");
for (int i = 0; i <= returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
}
strAdd = strReturnedAddress.toString();
Log.w("My Current loction address", strReturnedAddress.toString());
} else {
Log.w("My Current loction address", "No Address returned!");
}
} catch (Exception e) {
e.printStackTrace();
Log.w("My Current loction address", "Canont get Address!");
}
return strAdd;
}
