拉古南丹是对的。但是，如果您的目标是使用 Google 地图 API 获取“long_name”、位置等，您可能需要尝试以下方法来获取它。你可以得到响应是 JSON 的形式，我觉得它更有条理。你可以自己先试试网址：http ://maps.google.com/maps/api/geocode/json?latlng=23.0043673,72.5411868999996&sensor=false

我一直使用以下方法，它对我有用。它可能会帮助你得到你正在尝试的东西：

您可以获取纬度和经度，然后请求 google 服务器，以使用包含有关位置坐标的各种信息的 JSON 对象进行回复。这是功能：

public JSONObject getLocationInfo( double lat, double lng) {

    HttpGet httpGet = new HttpGet("http://maps.google.com/maps/api/geocode/json?latlng="+lat+","+lng+"&sensor=false");
    HttpClient client = new DefaultHttpClient();
    HttpResponse response;
    StringBuilder stringBuilder = new StringBuilder();

    try {
        response = client.execute(httpGet);
        HttpEntity entity = response.getEntity();
        InputStream stream = entity.getContent();
        int b;
        while ((b = stream.read()) != -1) {
            stringBuilder.append((char) b);
        }
    } catch (ClientProtocolException e) {
        } catch (IOException e) {
    }

    JSONObject jsonObject = new JSONObject();
    try {
        jsonObject = new JSONObject(stringBuilder.toString());
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return jsonObject;
}

现在您可以解析 JSON 以获得您想要的任何内容。例如，假设您想要完整的 formatted_address，您可以通过以下方式获得：

// get lat and lng value
JSONObject ret = getLocationInfo(lat, lng); 
JSONObject location;
String location_string;
try {
    //Get JSON Array called "results" and then get the 0th complete object as JSON        
    location = ret.getJSONArray("results").getJSONObject(0); 
    // Get the value of the attribute whose name is "formatted_string"
    location_string = location.getString("formatted_address");
    Log.d("test", "formattted address:" + location_string);
} catch (JSONException e1) {
    e1.printStackTrace();

}

如果您想了解更多关于如何从您将得到响应的 JSON 类型中提取所需数据的信息，请参阅Android - 如何解析 JSONObject 和 JSONArrays问题的答案。希望它可以帮助你。

更新：

希望您已阅读上述问题的答案。现在，例如：如果您想获取 JSON Array of address_components，那么只需执行类似的操作 

JSONArray addressComp = ret.getJSONArray("results").getJSONObject(0).getJSONArray("address_components");

现在你可以得到第一个long_name如下：

String long_name1 = addressComp.getJSONObject(0).getString("long_name");

因此，请尝试将此处的模式与您获得的 JSON 响应进行比较。这将使您了解如何获取任何元素。这里result是 JSONAArray，所以我把它作为 JSONArray。然后我取了resultJSONArray 的第一个对象，它name是另一个 JSONArray。然后因为我想得到第一个，所以我再次取了JSONArray 的第一个对象，然后要求获取名称为. 希望现在您对如何读取值有所了解。address_componentsvaluelong_nameaddress_componentvaluelong_name

PS：我没有运行最后两行但逻辑上制定。希望它能让你明白。一切顺利！

获得准确结果的简单方法。希望能帮助到你 ！

只需将此行放在您想要地址的位置：

String Adress_final=new GeocodeAPI().execute().get();

然后添加这个，

    //calling web geocoder api to get the address

    protected class GeocodeAPI extends AsyncTask<String, String, String>
    {

        String participantURL = Config.GooglePlacesAPI+"latlng="+Lat+","+Lng+"&sensor=false";
        JSONObject json;

        @Override
        protected void onPreExecute() 
        {
            System.out.println("participantURL==>>"+participantURL);
            // Create a progressdialog mProgressDialog
            mProgressDialog = new ProgressDialog(getActivity());
            // Set progressdialog title
            mProgressDialog.setTitle("Please Wait");
            // Set progressdialog message
            mProgressDialog.setMessage("Loading Location...");
            mProgressDialog.setIndeterminate(false);
            // Show progressdialog
            mProgressDialog.show();
        }


        @Override
        protected String doInBackground(String... params) {
            JSONParser jsonParser = new JSONParser();
            System.out.println("participantURL==>>"+participantURL);
            System.out.println("latitude & Longitude=="+Lat+","+Lng);
            List<NameValuePair> parameters = new ArrayList<NameValuePair>();


            try {
                json = jsonParser.getJSONFromUrl(participantURL, parameters);
                System.out.println("********Return from JSONParser class********");
                System.out.println("json=="+json);

                if (json != null) {

                    // get lat and lng value

                    JSONObject location;

                    try {
                        //Get JSON Array called "results" and then get the 0th complete object as JSON        
                        location = json.getJSONArray("results").getJSONObject(0);
                        System.out.println("location==>>>"+location);
                        // Get the value of the attribute whose name is "formatted_string"
                        location_string = location.getString("formatted_address");
                        System.out.println("location_string==>>>"+location_string);
                        Log.d("test", "formattted address:" + location_string);
                    } catch (JSONException e1) {
                        e1.printStackTrace();
                    }

                }
                }catch (Exception error) {
                    error.getMessage();
                }


            return location_string;**
