這篇文章主要介紹了Android編程實(shí)現(xiàn)根據(jù)經(jīng)緯度查詢地址并對(duì)獲取的json數(shù)據(jù)進(jìn)行解析的方法,結(jié)合實(shí)例形式分析了Android的經(jīng)緯度地址解析與json格式數(shù)據(jù)操作相關(guān)技巧,需要的朋友可以參考下

本文實(shí)例講述了Android編程實(shí)現(xiàn)根據(jù)經(jīng)緯度查詢地址并對(duì)獲取的json數(shù)據(jù)進(jìn)行解析的方法。分享給大家供大家參考，具體如下：

第一步：根據(jù)指定的URL從google 服務(wù)器上獲得包含地址的json格式的數(shù)據(jù)(其還提供xml格式的，但json解析效率比xml高)

private static StringBuffer getJSONData(String urlPath){
    try {
      URL url = new URL(urlPath);
      HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
      httpURLConnection.setReadTimeout(5000);
      httpURLConnection.setRequestMethod("GET");
      if(httpURLConnection.getResponseCode() == 200){
        InputStream inputStream = httpURLConnection.getInputStream();
        InputStreamReader isr = new InputStreamReader(inputStream);
        BufferedReader br = new BufferedReader(isr);
        String temp = null;
        StringBuffer jsonsb = new StringBuffer();
        while((temp = br.readLine()) != null){
          jsonsb.append(temp);
        }
        return jsonsb;
      }
    } catch (MalformedURLException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    } catch (IOException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
    return null;
}

傳入經(jīng)緯度作為參數(shù)

/**
* 根據(jù)經(jīng)緯度獲得地址
* @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數(shù)據(jù)：

public static boolean parseAddressJSON(StringBuffer sb){
    try {
      if(sb != null){
        JSONObject jsonAllData = new JSONObject(sb.toString());
        /**
         * 獲得一個(gè)長(zhǎng)度為1的JSON數(shù)組,如:[{數(shù)據(jù)內(nèi)容}]
         */
        String placemarkStr = jsonAllData.getString("Placemark");
        /**
         * 將placemarkStr數(shù)組類型字符串構(gòu)造成一個(gè)JSONArray對(duì)象
         */
        JSONArray placemarkArray = new JSONArray(placemarkStr);
        /**
         * Placemark標(biāo)簽內(nèi)容是一個(gè)長(zhǎng)度為1的數(shù)組,獲得數(shù)組的內(nèi)容并轉(zhuǎn)換成字符串
         */
        String jsonDataPlacemarkStr = placemarkArray.get(0).toString();
        /**
         * 對(duì)上面得到的JSON數(shù)據(jù)類型的字符串(jsonDataPlacemarkStr)進(jìn)行解析
         */
        JSONObject jsonDataPlacemark = new JSONObject(jsonDataPlacemarkStr);
        /**
         * 獲得標(biāo)簽AddressDetails的JSON數(shù)據(jù)
         */
        String jsonAddressDetails = jsonDataPlacemark.getString("AddressDetails");
        /**
         * 對(duì)上面得到的JSON數(shù)據(jù)類型的字符串(jsonAddressDetails)進(jìn)行解析
         */
        JSONObject jsonDataAddressJDetails = new JSONObject(jsonAddressDetails);
        /**
         * 獲得標(biāo)簽Country的JSON數(shù)據(jù)
         */
        String jsonCountry = jsonDataAddressJDetails.getString("Country");
        /**
         * 對(duì)上面得到的JSON數(shù)據(jù)類型的字符串(jsonCountry)進(jìn)行解析
         */
        JSONObject jsonDataCountry = new JSONObject(jsonCountry);
        /**
         * 對(duì)解析出來的感興趣的數(shù)據(jù)進(jìn)行封裝
         */
        LewatekGPSAddress lewatekGPSAddress = new LewatekGPSAddress();
        /**
         * 設(shè)置CountryName
         */
        lewatekGPSAddress.setCountryName(jsonDataCountry.getString("CountryName"));
        /**
         * 設(shè)置CountryNameCode
         */
        lewatekGPSAddress.setCountryNameCode(jsonDataCountry.getString("CountryNameCode"));
        /**
         * 獲得標(biāo)簽AdministrativeArea的JSON數(shù)據(jù)
         */
        String jsonAdministrativeArea = jsonDataCountry.getString("AdministrativeArea");
        /**
         * 對(duì)上面得到的JSON數(shù)據(jù)類型的字符串(jsonAdministrativeArea)進(jìn)行解析
         */
        JSONObject jsonDataAdministrativeArea = new JSONObject(jsonAdministrativeArea);
        /**
         * 設(shè)置AdministrativeAreaName
         */
        lewatekGPSAddress.setAdministrativeAreaName(jsonDataAdministrativeArea.getString("AdministrativeAreaName"));
        /**
         * 獲得標(biāo)簽Locality的JSON數(shù)據(jù)
         */
        String jsonLocality = jsonDataAdministrativeArea.getString("Locality");
        /**
         * 對(duì)上面得到的JSON數(shù)據(jù)類型的字符串(jsonLocality)進(jìn)行解析
         */
        JSONObject jsonDataLocality = new JSONObject(jsonLocality);
        /**
         * 設(shè)置LocalityName
         */
        lewatekGPSAddress.setLocalityName(jsonDataLocality.getString("LocalityName"));
        /**
         * 獲得標(biāo)簽DependentLocality的JSON數(shù)據(jù)
         */
        String jsonDependentLocality = jsonDataLocality.getString("DependentLocality");
        /**
         * 對(duì)上面得到的JSON數(shù)據(jù)類型的字符串(jsonDependentLocality)進(jìn)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 block
      e.printStackTrace();
    }
    return false;
}

從google服務(wù)器上獲得的json數(shù)據(jù)（提取對(duì)我有用的數(shù)據(jù)：CountryName、LocalityName、AdministrativeAreaName、DependentLocalityName，即中國(guó)上海市上海市浦東新區(qū)（中國(guó)湖南省衡陽(yáng)市衡山縣這樣的數(shù)據(jù)也能提?。?/p>
