我想解析Android Map中的反向地理编码的Google Map API

我想从xml中获取long_name,locality和country我已经尝试了各种帖子但是没有得到完美答案可以任何人请指导我,如何将这个XML解析成an​​droid？

Sho*_*uri 27

Raghunandan是对的.但是,如果您的目标是使用Google maps API获取"long_name",地点等,您可能需要尝试以下方式来获取它.你可以得到JSON形式的响应,我觉得它更有条理.您可以先尝试使用此网址:http://maps.google.com/maps/api/geocode/json？lalng = 23.0043673,72.5411868999996&sensor=false

我一直使用以下方法,它适用于我.它可能会帮助您获得正在尝试的内容:

您可以获取纬度和经度,然后请求谷歌服务器,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,假设您需要完整的formatted_address,以下是您可以获得的方法:

// 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();

}

如果您想了解更多如何从您将获得的JSON类型中提取所需数据,请参阅Android上的答案- 如何解析JSONObject和JSONArrays问题.希望它能帮到你.

更新:

希望你已经阅读了上述问题的答案.现在,例如:如果你想获得JSON数组address_components,那就做一些像 

JSONArray addressComp = ret.getJSONArray("results").getJSONObject(0).getJSONArray("address_components");
Run Code Online (Sandbox Code Playgroud)

现在你可以得到第一个long_name如下:

String long_name1 = addressComp.getJSONObject(0).getString("long_name");
Run Code Online (Sandbox Code Playgroud)

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.在这里,result是JSONARray,所以我把它作为JSONArray.然后我把第一个对象result,其JSONArray name是address_components和value是另一个JSONArray.然后因为我想获得第一个long_name,所以我再次address_component获取JSONArray 的第一个对象,然后要求获取value其名称为的组件long_name.希望你现在了解一下如何阅读价值观.

PS:我没有运行最后两行但是逻辑上制定了.希望它能让你明白.祝一切顺利!
