我正在嘗試一個位置應用程序，目前我在標記上有該位置的坐標?，F在，如何從已有的坐標中獲取位置名稱？我的代碼：//search add addressprivate void geoLocate() { Log.d( TAG, "geoLocate: geolocating" ); String searchString = mSearchText.getText().toString(); Geocoder geocoder = new Geocoder( MapActivity.this ); List<Address> list = new ArrayList<>(); try { list = geocoder.getFromLocationName( searchString, 1 ); } catch (IOException e) { Log.e( TAG, "geoLocate: IOException" + e.getMessage() ); } if (list.size() > 0) { Address address = list.get( 0 ); Log.d( TAG, "geoLocate: found a location: " + address.toString() ); moveCamera( new LatLng( address.getLatitude(), address.getLongitude() ), DEFAULT_ZOOM,address.getAddressLine( 0 ) ); }}這是我的標記// add markerpublic void addMarkers() { mMap.setOnMapClickListener( new GoogleMap.OnMapClickListener() { @Override public void onMapClick(LatLng latLng) { MarkerOptions markerOptions = new MarkerOptions(); markerOptions.position( latLng ); markerOptions.title( latLng.latitude + " : " + latLng.longitude ); mMap.clear(); mMap.animateCamera( CameraUpdateFactory.newLatLng( latLng ) ); mMap.addMarker( markerOptions ); shareView(); } } );}

您可以使用波紋管代碼來獲取基于 latlong 的地址
try {
Geocoder geocoder;
String city=null;
List<Address> yourAddresses;
geocoder = new Geocoder(this, Locale.getDefault());
yourAddresses = geocoder.getFromLocation(yourLatitude, yourLongitude, 1);
final String yourAddress = yourAddresses.get(0).getAddressLine(0);
if (yourAddresses != null && yourAddresses.size() > 0) {
android.location.Address address = yourAddresses.get(0);
@SuppressWarnings("MismatchedQueryAndUpdateOfStringBuilder") StringBuilder sb = new StringBuilder();
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
sb.append(address.getAddressLine(i)).append("\n");
}
city = address.getLocality();
Log.d("city", "onCreate: "+city);
}
} catch (IOException e) {
e.printStackTrace();
}
