使用经纬度获取特定地址

androidgeolocation
8

我需要知道是否有API可以获取当前位置的地址。使用位置管理器，我已经接收到了当前位置的纬度和经度，但我需要地址。

我尝试过以下API：

http://maps.googleapis.com/maps/api/geocode/json?latlng="+ lat + "," + lon + &sensor=true"

但是它没有显示确切的位置。有人能帮助我吗？@谢谢

你可以用 key=API_KEY 替换传感器，这样它就能正常工作了。 - Debasish Ghosh

从Geocoder对象中，您可以调用getFromLocation(double, double, int)方法。

例如：-

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();
    }

无法使用，地址始终为空，没有错误、异常，只有空白。 - marco

我已经创建了一个用于获取特定纬度和经度地址的类。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")) {

                            PIN = long_name;
                        }
                    }

许多人都给出了很多答案，但都错过了最关键的部分。以下是我如何实现的：您需要一个API密钥。 https://developers.google.com/maps/documentation/android-api/signup 耐心花时间仔细阅读代码。我在片段中使用了内部类。 代码：-

                            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;
    }

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);
            }
        });
