我需要知道是否有任何 API，我可以从那里接收当前地点的地址。使用位置管理器我已经收到当前地点的纬度和经度，但我需要地址。
我试过下面的api。
http://maps.googleapis.com/maps/api/geocode/json?latlng="+ lat + "," + lon + &sensor=true"
但它没有显示确切的位置。有人可以帮助我吗。@谢谢

从Geocoder对象，您可以调用getFromLocation(double, double, int)方法。
喜欢 ：-
private String getAddress(double latitude, double longitude) {
StringBuilder result = new StringBuilder();
try {
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0) {
Address address = addresses.get(0);
result.append(address.getLocality()).append("\n");
result.append(address.getCountryName());
}
} catch (IOException e) {
Log.e("tag", e.getMessage());
}
return result.toString();
}
另一个最佳答案是如何从谷歌地图中的经纬度坐标中获取城市名称？

我创建了一个类来获取特定纬度、经度的地址。你可以使用这个：
public class getReverseGeoCoding {
private String Address1 = "", Address2 = "", City = "", State = "", Country = "", County = "", PIN = "";
public void getAddress() {
Address1 = "";
Address2 = "";
City = "";
State = "";
Country = "";
County = "";
PIN = "";
try {
JSONObject jsonObj = parser_Json.getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + Global.curLatitude + ","
+ Global.curLongitude + "&sensor=true");
String Status = jsonObj.getString("status");
if (Status.equalsIgnoreCase("OK")) {
JSONArray Results = jsonObj.getJSONArray("results");
JSONObject zero = Results.getJSONObject(0);
JSONArray address_components = zero.getJSONArray("address_components");
for (int i = 0; i < address_components.length(); i++) {
JSONObject zero2 = address_components.getJSONObject(i);
String long_name = zero2.getString("long_name");
JSONArray mtypes = zero2.getJSONArray("types");
String Type = mtypes.getString(0);
if (TextUtils.isEmpty(long_name) == false || !long_name.equals(null) || long_name.length() > 0 || long_name != "") {
if (Type.equalsIgnoreCase("street_number")) {
Address1 = long_name + " ";
} else if (Type.equalsIgnoreCase("route")) {
Address1 = Address1 + long_name;
} else if (Type.equalsIgnoreCase("sublocality")) {
Address2 = long_name;
} else if (Type.equalsIgnoreCase("locality")) {
// Address2 = Address2 + long_name + ", ";
City = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_2")) {
County = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_1")) {
State = long_name;
} else if (Type.equalsIgnoreCase("country")) {
Country = long_name;
} else if (Type.equalsIgnoreCase("postal_code")) {
PIN = long_name;
}
}
// JSONArray mtypes = zero2.getJSONArray("types");
// String Type = mtypes.getString(0);
// Log.e(Type,long_name);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
public String getAddress1() {
return Address1;
}
public String getAddress2() {
return Address2;
}
public String getCity() {
return City;
}
public String getState() {
return State;
}
public String getCountry() {
return Country;
}
public String getCounty() {
return County;
}
public String getPIN() {
return PIN;
}
}
JSON解析器类
public class parser_Json {
public static JSONObject getJSONfromURL(String url) {
// initialize
InputStream is = null;
String result = "";
JSONObject jObject = null;
// http post
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
} catch (Exception e) {
Log.e("log_tag", "Error in http connection " + e.toString());
}
// convert response to string
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
Log.e("log_tag", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObject = new JSONObject(result);
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
return jObject;
}
}

这么多人给出了这么多的答案，但都错过了最关键的部分。以下是我如何做到这一点：您需要一个 API 密钥。 https://developers.google.com/maps/documentation/android-api/signup 只需花点时间耐心浏览代码。我在片段中使用了内部类。代码：-
private class DownloadRawData extends AsyncTask<LatLng, Void, ArrayList<String>> {
@Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog=new ProgressDialog(getActivity());
progressDialog.setMessage("Loading........");
progressDialog.setCancelable(false);
progressDialog.show();
}
@Override
protected ArrayList<String> doInBackground(LatLng... latLng) {
ArrayList<String> strings=retrieveData(latLng[0].latitude,latLng[0].longitude);
return strings;
}
@Override
protected void onPostExecute(ArrayList<String> s) {
super.onPostExecute(s);
if(progressDialog!=null)
progressDialog.dismiss();
LocationInfoDialog locationinfoDialog=new LocationInfoDialog(getActivity(),s);
locationinfoDialog.show();
locationinfoDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
locationinfoDialog.setCancelable(false);
}
}
private void init() {
address1 = "";
address2 = "";
city = "";
state = "";
country = "";
county = "";
PIN = "";
}
private String createUrl(double latitude, double longitude) throws UnsupportedEncodingException {
init();
return "https://maps.googleapis.com/maps/api/geocode/json?" + "latlng=" + latitude + "," + longitude + "&key=" + getActivity().getResources().getString(R.string.map_apiid);
}
private URL buildUrl(double latitude, double longitude) {
try {
Log.w(TAG, "buildUrl: "+createUrl(latitude,longitude));
return new URL(createUrl(latitude,longitude));
} catch (MalformedURLException e) {
e.printStackTrace();
Log.e(LOG_TAG, "can't construct location object");
return null;
}
catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return null;
}
private String getResponseFromHttpUrl(URL url) throws IOException {
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
InputStream in = urlConnection.getInputStream();
Scanner scanner = new Scanner(in);
scanner.useDelimiter("\\A");
if (scanner.hasNext()) {
return scanner.next();
} else {
return null;
}
} finally {
urlConnection.disconnect();
}
}
public String getAddress1() { return address1; }
public String getAddress2() { return address2; }
public String getCity() { return city; }
public String getState() { return state; }
public String getCountry() { return country; }
public String getCounty() { return county; }
public String getPIN() { return PIN; }
private ArrayList<String> retrieveData(double latitude, double longitude) {
ArrayList<String> strings=new ArrayList<>();
try {
String responseFromHttpUrl = getResponseFromHttpUrl(buildUrl(latitude, longitude));
JSONObject jsonResponse = new JSONObject(responseFromHttpUrl);
String status = jsonResponse.getString("status");
if (status.equalsIgnoreCase("OK")) {
JSONArray results = jsonResponse.getJSONArray("results");
JSONObject zero = results.getJSONObject(0);
JSONArray addressComponents = zero.getJSONArray("address_components");
String formatadd= zero.getString("formatted_address");
for (int i = 0; i < addressComponents.length(); i++) {
JSONObject zero2 = addressComponents.getJSONObject(i);
String longName = zero2.getString("long_name");
JSONArray types = zero2.getJSONArray("types");
String type = types.getString(0);
if (!TextUtils.isEmpty(longName)) {
if (type.equalsIgnoreCase("street_number")) {
address1 = longName + " ";
} else if (type.equalsIgnoreCase("route")) {
address1 = address1 + longName;
} else if (type.equalsIgnoreCase("sublocality")) {
address2 = longName;
} else if (type.equalsIgnoreCase("locality")) {
// address2 = address2 + longName + ", ";
city = longName;
} else if (type.equalsIgnoreCase("administrative_area_level_2")) {
county = longName;
} else if (type.equalsIgnoreCase("administrative_area_level_1")) {
state = longName;
} else if (type.equalsIgnoreCase("country")) {
country = longName;
} else if (type.equalsIgnoreCase("postal_code")) {
PIN = longName;
}
}
}
strings.add(formatadd);
strings.add(address1);
strings.add(address2);
strings.add(city);
strings.add(county);
strings.add(state);
strings.add(country);
strings.add(PIN);
}
} catch (Exception e) {
e.printStackTrace();
}
return strings;
}
像这样初始化：-
googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
@Override
public void onMapClick(LatLng latLng) {
markerOptions.position(latLng);
// Setting the title for the marker.
// This will be displayed on taping the marker
markerOptions.title(latLng.latitude + " : " + latLng.longitude);
googleMap.addMarker(markerOptions);
new DownloadRawData().execute(latLng);
}
});

试试这个：https ://www.google.com/maps/search/?api=1&query= latitude,longitude 并给出纬度和经度
