技术标签:
【中文标题】Android：我想以 json 格式从 google map api 中提取地址【英文标题】：Android: I want to extract the Address from google map api in json format 【发布时间】：2013-09-28 05:51:19 【问题描述】：在我的 android 应用程序中：我想像使用地理编码器一样提取位置、行政区域、国家名称、邮政编码、地址行，但我无法从 google map api JSON 格式中提取特定值，因为有时格式不同.
有人有想法吗？..
我的 JSON 飞行

我试过了
JSONObject jObject = new JSONObject(s);
JSONObject results= jObject.getJSONObject("results");
JSONObject address= jObject.getJSONObject("address_components");
Map<String,String> map = new HashMap<String,String>();
Iterator iter = address.keys();
while(iter.hasNext())
String key = (String)iter.next();
String value = menu.getString(key);
map.put(key,value);
它没有返回正确的值..
帮帮我。在此先感谢
【问题讨论】：
@Chimbu-只需添加您尝试过的代码以更好地理解 显示您的 JSON 文件以及到目前为止您尝试过的操作。 如果你真的希望你的代码工作，结果似乎是一个 JSONArray，而不是一个 JSONObject。 JSONArray 中的每个索引都是一个 JSONObject 【参考方案1】：这里是工作示例代码
JSONObject jsonObject;
String addre = null;
Address addr1 = null;
try
jsonObject = serverCall.getName(Double.parseDouble(latitude.getText().toString()),
Double.parseDouble(longitude.getText().toString()));
addre = ((JSONArray)jsonObject.get("results")).getJSONObject(0).getString("formatted_address");
if("OK".equalsIgnoreCase(jsonObject.getString("status")))
Log.d("status",jsonObject.getString("status"));
addr1 = new Address(Locale.getDefault());
for(int i=1;i<((JSONArray)jsonObject.get("results")).length()-2;i++)
JSONArray addrComp = ((JSONArray)jsonObject.get("results")).getJSONObject(i).getJSONArray("address_components");
//Toast.makeText(getApplicationContext(),addrComp.toString(),Toast.LENGTH_LONG).show();
// Log.d("Geocoder",addrComp.toString());
for(int j=0;j<addrComp.length();j++)
String neighborhood = ((JSONArray)((JSONObject)addrComp.get(j)).get("types")).getString(0);
if (neighborhood.compareTo("neighborhood") == 0)
String neighborhood1 = ((JSONObject)addrComp.get(j)).getString("long_name");
addr1.setSubThoroughfare(neighborhood1);
String locality = ((JSONArray)((JSONObject)addrComp.get(j)).get("types")).getString(0);
if (locality.compareTo("locality") == 0)
String locality1 = ((JSONObject)addrComp.get(0)).getString("long_name");
addr1.setLocality(locality1);
String subadminArea = ((JSONArray)((JSONObject)addrComp.get(j)).get("types")).getString(0);

if (adminArea.compareTo("administrative_area_level_1") == 0)
String adminArea1 = ((JSONObject)addrComp.get(j)).getString("long_name");
addr1.setAdminArea(adminArea1);

【参考方案2】：作为suggested by user370305:
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
addresses = geocoder.getFromLocation(latitude, longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getAddressLine(1);
