Question

我正在编写一个Android应用，它会获取您当前的位置，并使用Google商家信息网络服务返回您附近的商店列表。我能够回来（我认为是）有效的JSON，但是当我使用Android JSONObject库解析JSON时，我得到一个解析错误。

这是我的班级：

public class StoresNearMe {

    private String result = "";  
    private String googleAPIKey = "Omitted for this example"; 
    private String searchRadius = "50";
    private Location myLocation;
    final String TAG = getClass().getSimpleName();  

    public StoresNearMe(Location location){
        myLocation = location;
    }//StoresNearMe

    public String getStoresNearMe(){
        String result = "Nothing";
        result = callGoogleWebService(buildURLForGooglePlaces(myLocation));
        convertJSONtoArray(result);
        return result;
    }//getStoresNearMe


    private String callGoogleWebService(String url){  
            HttpClient httpclient = new DefaultHttpClient();  
            HttpGet request = new HttpGet(url);  
            //request.addHeader("deviceId", deviceId);  
            ResponseHandler<String> handler = new BasicResponseHandler();  
            try {  
                result = httpclient.execute(request, handler);  
            } catch (ClientProtocolException e) {  
                e.printStackTrace();  
            } catch (IOException e) {  
                e.printStackTrace();  
            }  
            httpclient.getConnectionManager().shutdown();  
            return result;
    }//callWebService

    private String buildURLForGooglePlaces(Location location){
        String baseUrl = "https://maps.googleapis.com/maps/api/place/search/json?";
        String lat = String.valueOf(location.getLatitude());
        String lon = String.valueOf(location.getLongitude());
        String url = baseUrl + "location=" + lat + "," + lon + "&" +
                     "radius=" + searchRadius + "&" + "sensor=false" +
                     "&" + "key=" + googleAPIKey;
        Log.d(TAG,url);
        return url;
    }//buildURLForGooglePlaces

    private void convertJSONtoArray(String rawJSON){
        try {
            JSONObject completeJSONObj = new JSONObject(rawJSON);
            String json = completeJSONObj.toString();
            Log.d(TAG,json);
            JSONObject results = completeJSONObj.getJSONObject("results");
        } catch (JSONException e) {
            Log.d(TAG,"JSON parsing error - fix it:" + e.getMessage());
        }
    }//convertJSONtoArray
}//StoresNearMe

这是我的电话回复的JSON：

感谢任何帮助 - 我不确定会出现什么问题。

谢谢！

Answer 1

问题是你正在尝试以对象的形式读取数组。

更改

JSONObject results = completeJSONObj.getJSONObject("results");

到

JSONArray results = completeJSONObj.getJSONArray("results");

并且解析异常消失了。

Answer 2

您的JSON应有效：示例：

{\"key\":\"value\" }

Google Places JSON在Android中引发了解析错误
