    {
        HttpService httpService = new HttpService("http://192.168.0.103/GetActiveGroupMember.php");
        try
        {
            httpService.ExecutePostRequest();

            if(httpService.getResponseCode() == 200)
            {
                result = httpService.getResponse();
                ArrayList<Integer> m_idlist = null;

                listid = new ArrayList<>();
                listid.add(result);
               // System.out.println("ListID...  "+listid+" ListId Size "+listid.size());
                System.out.println("ListID...  "+listid+" ListId Size "+listid.size());
             //   Log.d("Result", result);
                System.out.println("Result "+result);
                if(result != null)
                {
                    JSONArray jsonArray = null;
                    try {
                        jsonArray = new JSONArray(result);

                        JSONObject object;
                        JSONArray array;

                        member m;
                        members = new ArrayList<member>();

                        for(int i=0; i<jsonArray.length(); i++)
                        {
                            m= new member();
                            object = jsonArray.getJSONObject(i);

                          //  m.username = object.getString("username");
                            m.id = object.getInt("id");

                            members.add(m);

                            int m_id  = m.id;
                            System.out.println("mem_id  = "+m_id);

                            m_idlist = new ArrayList<Integer>();
                            m_idlist.add(i);

                          System.out.println("five no id = "+m_idlist.get(i)); // TO print all Id

                        }
                         if(m_idlist.size()>5){
                            System.out.println("five no id = "+m_idlist.get(5));
                           }
                     //   System.out.println("Total member  = "+members.size());

                    }

Thank you so much.

Your list only contains **one** item, so there is no item with index 5. — Denny, Apr 20 '17 at 10:16
System.out.println("five no id = "+m_idlist.get(5)); you're pushing the system at index 5 when it only have 1 item in list — jace, Apr 20 '17 at 10:17
`m_idlist.get(5)` if your list is not having 6 elements in total than it will always throw this error. Add a check for list size and put this code in that condition. — Vivek Mishra, Apr 20 '17 at 10:17
Agreed with everybody else, you need to have a check statement ( a simple if statement ) to check if the element exists — Ryan Turnbull, Apr 20 '17 at 10:18

System.out.println("five no id = "+m_idlist.get(5));

You probably have no element in the list with index 5, add a if statement to check your index with the size of the list.

In your case:

if (5 < m_idlist.size()) { ... }

k.sir, Actually I have 10 id in int m_id = m.id; and i am adding m_id into Arraylistlist as m_idlist.add(m_id); and after that I am getting the id of 5th no position by using System.out.println("five no id = "+m_idlist.get(5)); Then it returns 1st no of position id..please help me . – gaikwad Apr 20 '17 at 10:48
No, it is said that there is only 1 element `Invalid index 5, size is 1` – AxelH Apr 20 '17 at 11:10
Then what are the println's printing as @bhaumiksoni asked? – Zezima Apr 20 '17 at 11:21

you have to declare this line m_idlist = new ArrayList<Integer>(); above of for loop
