How to fetch value from parse class containing Array type column of strings in android

Question

I have a class named UserData on parse.com, containing column name as usersports which is of array type,i successfully added strings in the array, but i got stuck while fetching the array values and displaying to a list. say: parse array type is like this,

["Cycling","Diving","Equestrian"]

I have tested using JsonArray for parsing the array values from parse but not succeed. In my code getting checkuserSportarray as null. Please help me out.

Below is my code:

  private void userDetailfromParse(){

         ParseQuery<ParseObject> query = ParseQuery.getQuery(Sportapp.USERDATA);
         query.whereEqualTo(Sportapp.USER_GOOGLE_ID, google_id_from_preference.trim());
         query.getFirstInBackground(new GetCallback<ParseObject>() {
         @SuppressWarnings("unchecked")
        public void done(final ParseObject login_data, ParseException e) {
             if (login_data == null) {
                        Log.d("Data", "The getFirst request failed. in profile"+e.getCode());
                      }
                 else{
                     userEmail = login_data.getString(Sportapp.USER_EMAIL);
                     userName = login_data.getString(Sportapp.USER_NAME);                                       
                     userGender = login_data.getString(Sportapp.USER_GENDER);

                    checkuserSportarray = login_data.getJSONArray(Sportapp.USERDATA);

                    }                         

               }
             });
        }

Are you sure Sportapp.USERDATA contains ["Cycling","Diving","Equestrian"]? — Pedro Oliveira

Sportapp.USERDATA is my class name, i have a column named usersports storing ["Cycling","Diving","Equestrian"] which is of array type — User413

So you're trying to create an array from your class name? Show us your login_data content — Pedro Oliveira

i already created array, in the code Snippet, i posted above, in that i am tying to fetch those string values from the array. — User413

If checkuserSportarray is null that means that you are not "creating an array" like you're saying. I suggest you debug your login_data content and check it's structure. If you post it here it will be easier to help you — Pedro Oliveira

works fine for me:

    List<String> list11 =  new ArrayList<String>();

    ParseQuery<ParseObject> pQuery = ParseQuery.getQuery("UserData");
    pQuery.whereEqualTo(Sportapp.USER_GOOGLE_ID, google_id_from_preference.trim());
    pQuery.findInBackground(new FindCallback<ParseObject>() {

        @Override
        public void done(List<ParseObject> list, ParseException e) {
            if (e==null) {
            if (list.size()>0) {
                ParseObject p = list.get(0);
                if (p.getList("usersports")!=null) {
                    list11 =  p.getList("usersports");
                }
                else
                {
                    list11= null;
                }
                }}
                        }
                        });

use getList method to get the data from array column of parse table

now if you want to get all individual data of parsed array ,you can simply apply looping on **list11**.

pass your column name in getJSONArray method like this:-

checkuserSportarray = login_data.getJSONArray("usersports");
