Question

hi am facing some kind of issue with the code . Following is my code to generate json data

for(int i=0; i < allEds.size(); i++){
                String edsText = allEds.get(i).getText().toString();                                           
               //spinner = allSpns.get(i);
               String spinSelected=allSpns.get(i).getSelectedItem().toString();                  
               try
                {
                   JSONObject json = new JSONObject();          
                   json.put("FieldName", edsText);
                   json.put("FieldType",spinSelected);
                   parent.accumulate("data", json);



                }
                catch (JSONException e)
                {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                }                   

            }

It work fine and getting if i made more than one entry to json

correct out put
{"data":[{"FieldType":"Character","FieldName":"fffg"},{"FieldType":"Character","FieldName":"fg"]}

When only one entry as json it gives the following out

{"data":{"FieldType":"Character","FieldName":"ffg","Id":0}}

While parsing the second json am getting errors..Any thing wrong on my code?

code i used for parsing json

JSONObject jsonObj = new JSONObject(folderStructure);
        JSONArray data = jsonObj.getJSONArray("data");
         //ArrayList<HashMap<String, String>> folderList = new ArrayList<HashMap<String, String>>();
        for(int i=0; i<data.length(); i++)
        {

            //HashMap<String, String> map = new HashMap<String, String>();
             JSONObject obj=data.getJSONObject(i);
             String id = obj.getString("Id"); 
                String valueName = obj.getString("FieldName"); 
                String valueType = obj.getString("FieldType"); 
}

Answer 1

JSONObject parent = new JSONObject();
JSONArray jdata = new JSONArray();

    try{
         for(int i=0; i < allEds.size(); i++){
             JSONObject childObj = new JSONObject();         
             childObj .put("FieldName", allEds.get(i).getText().toString());
             childObj .put("FieldType",allSpns.get(i).getSelectedItem().toString());

             jdata .put(childObj).toString();
            }
          parent.put("data",jdata);
       }
       catch (JSONException e){
         // TODO Auto-generated catch block
         e.printStackTrace();
       }
