如何从经纬度获得完整的地址？
我想在android中获取纬度和经度的值
- 街道地址
- 市，州
- 压缩
- 完整地址
如何做到这一点？
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 有关可用详细信息的更多信息，请参阅Android-Location-Address
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; }
从Lat-Long （地理坐标） 获取地址有最后一个技巧 。 您可以简单地通过谷歌地图Web服务传递经纬度。 它只是一个GET方法的networking服务。
它将返回可以轻松parsing的JSON响应来获取地址。 这个URL是：
http://maps.googleapis.com/maps/api/geocode/json?latlng=32,75&sensor=true
你可以用 lat来代替32,75 。
城市与乡村并不总是在地址1号线和2号线…
例子就在这里
所以，
Geocoder geocoder = new Geocoder(context, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(latitude,longitude, 1); String city = addresses.get(0).getLocality(); String state = addresses.get(0).getAdminArea(); String zip = addresses.get(0).getPostalCode(); String country = addresses.get(0).getCountryName();
在onCreate（）..
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 0, this); Criteria criteria = new Criteria(); String bestProvider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(bestProvider); if (location == null) { Toast.makeText(getApplicationContext(), "GPS signal not found", 3000).show(); } if (location != null) { Log.e("locatin", "location--" + location); Log.e("latitude at beginning", "@@@@@@@@@@@@@@@" + location.getLatitude()); onLocationChanged(location); }
在onLocationChanged（）中写入代码
@Override public void onLocationChanged(Location location) { Geocoder geocoder; List<Address> addresses; geocoder = new Geocoder(this, Locale.getDefault()); latitude = location.getLatitude(); longitude = location.getLongitude(); Log.e("latitude", "latitude--" + latitude); try { Log.e("latitude", "inside latitude--" + latitude); addresses = geocoder.getFromLocation(latitude, longitude, 1); if (addresses != null && addresses.size() > 0) { String address = addresses.get(0).getAddressLine(0); 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(); locationTxt.setText(address + " " + city + " " + country); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }
使用GeoCoder从经度和纬度获取地址。

您正在寻找术语“地理编码”。
小故事是你需要做的：
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。
只要使用这种方法，并通过你的拉特，长。
public static void getAddress(Context context, double LATITUDE, double LONGITUDE) { //Set Address try { Geocoder geocoder = new Geocoder(context, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1); if (addresses != null && addresses.size() > 0) { 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 Log.d(TAG, "getAddress: address" + address); Log.d(TAG, "getAddress: city" + city); Log.d(TAG, "getAddress: state" + state); Log.d(TAG, "getAddress: postalCode" + postalCode); Log.d(TAG, "getAddress: knownName" + knownName); } } catch (IOException e) { e.printStackTrace(); } return; }
你可以很容易地使用下面的代码来获取地址。

你可以创build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 + "]"); } } }
然后使用实例化它
GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if called from an activity and not from a fragment mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);
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; } }
double latitude = networkLocation.getLatitude(); double longitude = networkLocation.getLongitude(); LocationAddress locationAddress = new LocationAddress(); locationAddress.getAddressFromLocation(latitude , longitude , getApplicationContext(), new GeocoderHandler());

尝试使用地理编码器使用以下代码：
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(",", "") + ", "; } }
