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
}

您可以使用此方法对正确完整的地址进行地理编码
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。
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
要了解更多可用细节,请查看Android-Location-Address
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);
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"
}
}
