通过复杂的Google Geocoding JSON对象中的键获取值-Java-android

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了通过复杂的Google Geocoding JSON对象中的键获取值-Java-android相关的知识，希望对你有一定的参考价值。
我使用此有用的code snippet来获取我的android应用程序中的当前位置，现在我想获取route（街道地址），street_number，postal_code和country（始终为long_name ）在Google Geocoding JSON对象中。目前，我使用do-while循环，然后拆分formatted_address以得到所需的结果，但我认为最好通过其键访问该值。
JSON看起来像这样：
"results": [
"types": [
"street_address"
],
"formatted_address": "RotenturmstraÃe 2, 1010 Vienna, Austria",
"address_components": [
"types": [

"short_name": "2",
"long_name": "2"

这是我的代码：
public static JSONObject getLocationInfo(double lat, double lng)
HttpGet httpGet = new HttpGet("http://maps.googleapis.com/maps/api/geocode/json?latlng="+ lat+","+lng +"&sensor=true");
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;
public static String getCurrentLocationViaJSON(double lat, double lng)
JSONObject jsonObj = getLocationInfo(lat, lng);
Log.i("JSON string =>", jsonObj.toString());
String currentLocation = "testing";
String street_address = null;
String postal_code = null;
try
String status = jsonObj.getString("status").toString();
Log.i("status", status);
if(status.equalsIgnoreCase("OK"))
JSONArray results = jsonObj.getJSONArray("results");
int i = 0;
Log.i("i", i+ "," + results.length() ); //TODO delete this
do
JSONObject r = results.getJSONObject(i);
JSONArray typesArray = r.getJSONArray("types");
String types = typesArray.getString(0);
if(types.equalsIgnoreCase("street_address"))
street_address = r.getString("formatted_address").split(",")[0];
Log.i("street_address", street_address);
else if(types.equalsIgnoreCase("postal_code"))
postal_code = r.getString("formatted_address");
Log.i("postal_code", postal_code);
if(street_address!=null && postal_code!=null)
currentLocation = street_address + "," + postal_code;
Log.i("Current Location =>", currentLocation); //Delete this
i = results.length();
i++;
while(i<results.length());
Log.i("JSON Geo Locatoin =>", currentLocation);
return currentLocation;
catch (JSONException e)
Log.e("testing","Failed to load JSON");
e.printStackTrace();
return null;
任何帮助将不胜感激。
答案
在该代码示例中，它们使用JSONObject，因此您将要使用getJSONObject(i)，getJSONArray()和getString()解析数据。 另一答案
此代码将始终为您提供地址。已验证！以上是关于通过复杂的Google Geocoding JSON对象中的键获取值-Java-android的主要内容，如果未能解决你的问题，请参考以下文章
