Geocoder geocoder =new Geocoder(mContext, Locale.getDefault());

Address address=null;
String zip=null;

StringBuffer st=new StringBuffer();
// If the reverse geocode returned an address
if (addresses != null && addresses.size() > 0) {

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
public static String getAddressFromLatLng(Context context, LatLng latLng) {
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(context, Locale.getDefault());
try {
addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
return addresses.get(0).getAddressLine(0);
} catch (Exception e) {
e.printStackTrace();
return "";
}
}
你可以创建类
public class GeoLocation {
private Context mContext;
private String mLatitude;
private String mLongtitude;
private String mStreet;
private String mHouseNumber;
private String mPostalCode;
private String mCity;
private Location mMarkerLocation;
public GeoLocation (Context context) {
mContext = context;
}
public String getStreet () {
return mStreet;
}
public String getHouseNumber () {
return mHouseNumber;
}
public String getPostalCode () {
return mPostalCode;
}
public String getCity () {
return mCity;
}
public String getLatitude () {
return mLatitude;
}
public String getLongtitude () {
return mLongtitude;
}
// Lookup address via reverse geolocation
// Call this one
public void lookUpAddress (Location markerLocation) {
mMarkerLocation = markerLocation;
if (Geocoder.isPresent()) {
(new GetAddressTask(mContext)).execute();
}
}
public class GetAddressTask extends AsyncTask<android.location.Location, Void, String> {
public GetAddressTask (Context context) {
super();
mContext = context;
}
@Override
protected String doInBackground (android.location.Location... params) {
Geocoder geocoder =
new Geocoder(mContext, Locale.getDefault());
android.location.Location location = params[0];
List<Address> addresses = null;
try {
if (mMarkerLocation != null) {
addresses = geocoder.getFromLocation(mMarkerLocation.getLatitude(),
mMarkerLocation.getLongitude(), 1);
}
} catch (IOException exception) {
Log.e("ComplaintLocation",
"IO Exception in getFromLocation()", exception);
return ("IO Exception trying to get address");
} catch (IllegalArgumentException exception) {
String errorString = "Illegal arguments " +
Double.toString(location.getLatitude()) + " , " +
Double.toString(location.getLongitude()) + " passed to address service";
Log.e("LocationSampleActivity", errorString, exception);
return errorString;
}
if (addresses != null && addresses.size() > 0) {
Address address = addresses.get(0);
if (address.getMaxAddressLineIndex() > 0) {
return String.format(
"%s/%s/%s/%s/%s/%s",
address.getLatitude(), // 0
address.getLongitude(), // 1
address.getThoroughfare(), // 2
address.getSubThoroughfare(), //3
address.getPostalCode(), // 4
address.getLocality()); // 5
} else {
return String.format(
"%s/%s/%s/%s",
address.getLatitude(), // 0
address.getLongitude(), // 1
address.getPostalCode(), // 2
address.getLocality()); // 3
}
} else return "No address found";
}
// Format address string after lookup
@Override
protected void onPostExecute (String address) {
String[] addressFields = TextUtils.split(address, "/");
Log.d("ADDRESS ARRAY", Arrays.toString(addressFields));
// Workaround: doInBackground can only return Strings instead of, for example, an
// Address instance or a String[] directly. To be able to use TextUtils.isEmpty()
// on fields returned by this method, set each String that currently reads "null" to
// a null reference
for (int fieldcnt = 0; fieldcnt < addressFields.length; ++fieldcnt) {
if (addressFields[fieldcnt].equals("null"))
addressFields[fieldcnt] = null;
}
switch (addressFields.length) {
case 4:
mStreet = null;
mHouseNumber = null;
mLatitude = addressFields[0];
mLongtitude = addressFields[1];
mPostalCode = addressFields[2];
mCity = addressFields[3];
break;
case 6:
mLatitude = addressFields[0];
mLongtitude = addressFields[1];
mStreet = addressFields[2];
mHouseNumber = addressFields[3];
mPostalCode = addressFields[4];
mCity = addressFields[5];
break;
default:
mLatitude = null;
mLongtitude = null;
mStreet = null;
mHouseNumber = null;
mPostalCode = null;
mCity = null;
break;
}
Log.d("GeoLocation Street", mStreet);
Log.d("GeoLocation No.", mHouseNumber);
Log.d("GeoLocation Postalcode", mPostalCode);
Log.d("GeoLocation Locality", mCity);
Log.d("GeoLocation Lat/Lng", "[" + mLatitude + ", " + mLongtitude +
"]");
}
}
}
然后使用
GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if
called from an activity and not from a fragment
mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);
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。
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。
