如何在自定义数组列表中添加静态字段？

Question

Hi i am using json parsing in my project. I have following Response and i am setting it to spinner.

{"success":1,"languages":[{"id":"2","name":"telugu"},{"id":"3","name":"English"},{"id":"4","name":"Tamil"}]}

now issue is that I want to add one id and name static. id : 1, name : All

Can any one help me how to add this?

 try {
     JSONArray jsonArray = response.getJSONArray("languages");
     for (int i = 0; i < jsonArray.length(); i++) {
         try {

             JSONObject obj = jsonArray.getJSONObject(i);
             LanguageModel catobj = new LanguageModel();

             catobj.setLangid(obj.getString("id"));
             catobj.setLangname(obj.getString("name"));

             LanguageModel alldata = new LanguageModel();
             alldata.setLangid(("1"));
             alldata.setLangname(("All"));
             langList.add(0, alldata);
             langList.add(catobj);

         } catch (JSONException e) {
             e.printStackTrace();
         }

     }

 } catch (JSONException e) {
     e.printStackTrace();
 }

Answer 1

take this line out of for loop

LanguageModel alldata = new LanguageModel();
 alldata.setLangid(("1"));
 alldata.setLangname(("All"));
 langList.add(0,alldata);

Answer 2

Problem here is that you are adding id : 1, name : All inside for loop which would cause it to be added many times. This should be added only once.

Remove following four lines from for loop

LanguageModel alldata = new LanguageModel();
alldata.setLangid(("1"));
alldata.setLangname(("All"));
langList.add(0,alldata);

and put just above for statement.

Answer 3

You are getting data from loop and fill and arraylist . Just remove this line.

LanguageModel alldata = new LanguageModel();
alldata.setLangid(("1"));
alldata.setLangname(("All"));
langList.add(0,alldata);
