Ошибка Java HashMap: java.lang.ClassCastException: java.lang.Integer нельзя передать в java.lang.String

Question

Я извлекаю HashMap из JSONArray и отправляю его в SQLite. Это дает мне. java.lang.ClassCastException: java.lang.Integer нельзя передать в java.lang.String. Ошибка преобразования HashMap.

Тип HashMap>.

for(int i=0;i<adsarray.length();i++){ 
     JSONObject obj=adsarray.getJSONObject(i); 
     HashMap mapReceivedAdDetails=new HashMap(); 
     HashMap mapBusinessInfo=new HashMap(); 



     //mapBusinessInfo.put 
     mapReceivedAdDetails.put("RecAdId", obj.getInt("received_ad_id")); 
     mapReceivedAdDetails.put("RecBusinessId",obj.getInt("business_id")); 
     mapReceivedAdDetails.put("RecBusinessId",obj.getInt("user_id")); 
     mapReceivedAdDetails.put("RecAdtitle",obj.getString("received_ad_title")); 
     mapReceivedAdDetails.put("RecAdDetail",obj.getString("received_ad_detail")); 
     mapReceivedAdDetails.put("RecBusinessZip",obj.getString("business_zip")); 
     mapReceivedAdDetails.put("RecBusinessCountry", obj.getString("business_country")); 
     mapReceivedAdDetails.put("AdCreated", obj.getString("adreceived_created")); 
     mapReceivedAd.put(i, mapReceivedAdDetails); 

    //Log.i("ReceivedId",mapReceivedAd.toString()); 

     mapBusinessInfo.put("BusinessId",obj.getInt("business_id")); 
     mapBusinessInfo.put("BusUserId",obj.getInt("user_id")); 
     mapBusinessInfo.put("BusName",obj.getString("business_name"));

Answer 1

Вы можете свободно конвертировать Hashmap в String не будет никаких обид на всех. Но то, что вы делаете, у вас есть Hasmap, называемый mapReceivedAdDetails, и вы пытаетесь преобразовать другую переменную, которая не была показана в фрагменте mapReceivedAd.

Так вместо того, чтобы делать

mapReceivedAd.toString(); 

ли

mapReceivedAdDetails.toString();
