如何将String转换为JsonObject？

Question

{
   "error":null,
   "countries":[
      {
         "id":1,
         "description":"Slovensko",
         "locale":"sk_SK",
         "zipRegexp":"/^\\d{3}\\ ?\\d{2}$/"
      },
      {
         "id":2,
         "description":"Česká republika",
         "locale":"cs_CZ",
         "zipRegexp":null
      },
      {
         "id":3,
         "description":"Afganistan",
         "locale":"en_EN",
         "zipRegexp":null
      }
    ]
}

and so on so on, now I need to convert it to JsonObject on Android. But I cannot convert it to String because of double commas . How can it be done? I need somethink like this:

JsonObjet.JsonFromString('{"error":null,"countries":[{"id":1,"description":"Slovensko","locale":"sk_SK","zipRegexp":"/^\\d{3}\\ ?\\d{2}$/"},{"id":2,"description":"Česká republika","locale":"cs_CZ","zipRegexp":null}}');

this is not the answer:

JSONObject getJSON = new JSONObject("{"error":null,"countries":[{"id":1,"description":"Slovensko","locale‌​":"sk_SK","zipRegexp":"/^\\d{3}\\ ?\\d{2}$/"},{"id":2,"description":"Česká republika","locale":"cs_CZ","zipRegexp":null}}");

because of double commas.

thanks

Answer 1

JSONObject getJSON = new JSONObject("Your String");

Edit:

String yourString = "{"+"\"error\""+":"+"\"no error\""+"}";
System.out.println(yourString );

Then yourString will be {"error":"no error"} . Implement the same way for the String you have. Then convert the above yourString to JSONObject as

JSONObject getJSON = new JSONObject(yourString);

Answer 2

How do you get the JSon??? If you are getting it from a HttpClient then get it as a InputStream and use the bufferedReader to convert it into a String buffer.

Answer 3

JSONObject jsonObject = new JSONObject(res);

Answer 4

Try this :

        InputStream mIs = null;
        String result = "";
        JSONObject jObjectLogin = null;

           HttpClient httpclient = new DefaultHttpClient();
           String urlWithNoSpace=  url.replace(" ", "%20");
           HttpGet httpget = new   HttpGet(urlWithNoSpace);
            HttpResponse response = httpclient.execute(httpget);
            HttpEntity entity = response.getEntity();
            mIs = entity.getContent();

            String result = "";
            BufferedReader bufferReader = new BufferedReader(new InputStreamReader(mIs,"UTF-8"),8);
            StringBuilder stringBuilder = new StringBuilder();
            String line = null;

            while ((line = bufferReader.readLine()) != null) {

             //if require change or edit this condition.     
             if(line.trim().equals("\n"))
                    continue;
                stringBuilder.append(line + "\n");
            }
            mIs.close();
            result=stringBuilder.toString();

Now as according to string format(which is in Json format) you can fetch array and objects from it.

     JSONObject jsonObject=result ;
     JSONArray jsonArray=jsonObject.getJSONArray("countries");

now put loop and find values fron Array.
