null){jsonsb.append(temp);}return jsonsb;}} catch (MalformedURLException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return null;}传入经纬度作为参数/*** 根据经纬度获得地址* param latitude* param longitude* return*/public static StringBuffer getCurrentAddressByGPS(long latitude,long longitude){StringBuffer stringBuffer new StringBuffer();stringBuffer.append(GOOGLE_GPS_PREFIX).append(latitude).append(,).append(longitude).append(GOOGLE_GPS_SUFFIX);return getJSONData(stringBuffer.toString());}第三解析json数据public static boolean parseAddressJSON(StringBuffer sb){try {if(sb ! null){JSONObject jsonAllData new JSONObject(sb.toString());/*** 获得一个长度为1的JSON数组,如:[{数据内容}]*/String placemarkStr jsonAllData.getString(Placemark);/*** 将placemarkStr数组类型字符串构造成一个JSONArray对象*/JSONArray placemarkArray new JSONArray(placemarkStr);/*** Placemark标签内容是一个长度为1的数组,获得数组的内容并转换成字符串*/String jsonDataPlacemarkStr placemarkArray.get(0).toString();/*** 对上面得到的JSON数据类型的字符串(jsonDataPlacemarkStr)进行解析*/JSONObject jsonDataPlacemark new JSONObject(jsonDataPlacemarkStr);/*** 获得标签AddressDetails的JSON数据*/String jsonAddressDetails jsonDataPlacemark.getString(AddressDetails);/*** 对上面得到的JSON数据类型的字符串(jsonAddressDetails)进行解析*/JSONObject jsonDataAddressJDetails new JSONObject(jsonAddressDetails);/*** 获得标签Country的JSON数据*/String jsonCountry jsonDataAddressJDetails.getString(Country);/*** 对上面得到的JSON数据类型的字符串(jsonCountry)进行解析*/JSONObject jsonDataCountry new JSONObject(jsonCountry);/*** 对解析出来的感兴趣的数据进行封装*/LewatekGPSAddress lewatekGPSAddress new LewatekGPSAddress();/*** 设置CountryName*/lewatekGPSAddress.setCountryName(jsonDataCountry.getString(CountryName));/*** 设置CountryNameCode*/lewatekGPSAddress.setCountryNameCode(jsonDataCountry.getString(CountryNameCode));/*** 获得标签AdministrativeArea的JSON数据*/String jsonAdministrativeArea jsonDataCountry.getString(AdministrativeArea);/*** 对上面得到的JSON数据类型的字符串(jsonAdministrativeArea)进行解析*/JSONObject jsonDataAdministrativeArea new JSONObject(jsonAdministrativeArea);/*** 设置AdministrativeAreaName*/lewatekGPSAddress.setAdministrativeAreaName(jsonDataAdministrativeArea.getString(AdministrativeAreaName));/*** 获得标签Locality的JSON数据*/String jsonLocality jsonDataAdministrativeArea.getString(Locality);/*** 对上面得到的JSON数据类型的字符串(jsonLocality)进行解析*/JSONObject jsonDataLocality new JSONObject(jsonLocality);/*** 设置LocalityName*/lewatekGPSAddress.setLocalityName(jsonDataLocality.getString(LocalityName));/*** 获得标签DependentLocality的JSON数据*/String jsonDependentLocality jsonDataLocality.getString(DependentLocality);/*** 对上面得到的JSON数据类型的字符串(jsonDependentLocality)进行解析*/JSONObject jsonDataDependentLocality new JSONObject(jsonDependentLocality);lewatekGPSAddress.setDependentLocalityName(jsonDataDependentLocality.getString(DependentLocalityName));Log.e(TAG,lewatekGPSAddress.toString());return true;}} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}return false;}从google服务器上获得的json数据(提取对我有用的数据CountryName、LocalityName、AdministrativeAreaName、DependentLocalityName即中国上海市上海市浦东新区(中国湖南省衡阳市衡山县这样的数据也能提取)){name: 31.20322202833381,121.59876351250254,Status: {code: 200,request: geocode},Placemark: [ {id: p1,address: 中国上海市浦东新区祖冲之路994号-1088号,AddressDetails: {Accuracy : 8,Country : {AdministrativeArea : {AdministrativeAreaName : 上海市,Locality : {DependentLocality : {DependentLocalityName : 浦东新区,Thoroughfare : {ThoroughfareName : 祖冲之路994号-1088号}},LocalityName : 上海市}},CountryName : 中国,CountryNameCode : CN}},ExtendedData: {LatLonBox: {north: 31.2070152,south: 31.2007199,east: 121.6018752,west: 121.5955799}},Point: {coordinates: [ 121.5986103, 31.2038252, 0 ]}} ]}Value [{id:p1,ExtendedData:{LatLonBox:{south:31.2007199,west:121.5955799,east:121.6018752,north:31.2070152}},address:中国上海市浦东新区祖冲之路994号-1088号,Point:{coordinates:[121.5986103,31.2038252,0]},AddressDetails:{Country:{CountryNameCode:CN,CountryName:中国,AdministrativeArea:{Locality:{LocalityName:上海市,DependentLocality:{DependentLocalityName:浦东新区,Thoroughfare:{ThoroughfareName:祖冲之路994号-1088号}}},AdministrativeAreaName:上海市}},Accuracy:8}}] at Placemark of type org.json.JSONArray cannot be converted to JSONObject关于Android应用中如何解析获取的json数据就分享到这里了希望以上内容可以对大家有一定的帮助可以学到更多知识。如果觉得文章不错可以把它分享出去让更多的人看到。
