                for(int j=0;j<tagarray.length();j++){
                    tagobject = tagarray.getJSONObject(j);
                    if(tagobject!=null){

tagobject = tagarray.getJSONObject(j).toString(); and then add tagobject in your array list tagname.add(tagobject); is it not working for you –  MuraliGanesan Feb 20 '13 at 8:05
    
NO it will not work..as because tagname is string array list and its cant take the object –  Sangita Feb 20 '13 at 8:16

because current "tags" array not content any JSONObject it contain only String values . get values as :

// Create Hashmap before starting parsing

HashMap<String,ArrayList<String>> mapQusttags=
                            new HashMap<String,ArrayList<String>>();

//your code here ......

tagarray = jsontagobj.getJSONArray("tags");
// Create ArrayList
ArrayList<String> tagsList = new ArrayList<String>();
 for(int j=0;j<tagarray.length();j++){
     tagsList.add(tagarray.getString(j)); 
  } 

// Store ArrayList inside HashMap with question id

String str_qstid=jsontagobj.getString("question_id");

mapQusttags.put(str_qstid,tagsList);

k..let me check.. –  Sangita Feb 20 '13 at 10:50
    
here based on question id the tag will allocate right.. –  Sangita Feb 20 '13 at 10:53
    
@Sangita : after parsing when u need tags of any question just use ArrayList<String> arrtags=mapQusttags.get(<pass question id here>); then u will get all tags inside arrtags ArrayList –  ρяσѕρєя K Feb 20 '13 at 10:55

You're making it complex, there is no need to get the JSONObject.

ArrayList<String> tagsList = new ArrayList<String>();
tagarray = jsontagobj.getJSONArray("tags");
for(int j=0;j<tagarray.length();j++){
   tagsList.add(tagarray.getString(j)); 
}

the main thing is when we assign the taglist it came the entire list of the tag minimum 50..i –  Sangita Feb 20 '13 at 10:00
