How to check if two values are same or not from a JSONArray in android?

Question

I am getting a Json response as below:

{
messages: [
{
id: "83",
payer_id: "5",
payee_id: "24",
payer_name: "vishal ",
payee_name: "ravi ",
payer_image: "upload/123.jpg",
payee_image: "upload/crop_110x110_1338731270_591178.jpg",
dispute_id: "43",
subject: "",
message_body: "dwedwde",
added_on: "2014-01-16 04:06:35",
sender_id: "5",
read: "1"
},
{
id: "716",
payer_id: "5",
payee_id: "6",
payer_name: "vishal ",
payee_name: "vishal  ",
payer_image: "upload/123.jpg",
payee_image: "upload/yt.png",
dispute_id: "43",
subject: "",
message_body: "smthig",
added_on: "2014-05-27 02:26:04",
sender_id: "6",
read: "1"
}
],
status: "success"
}

I have coded as below for parsing.

ArrayList<HashMap<String, String>> msgList;
msgList = new ArrayList<HashMap<String, String>>();
String jsonStr = sh.makeServiceCall(disputeURL, BackendAPIService.GET);

            Log.print("Response: ", "> " + jsonStr);

            try {
                if (jsonStr != null) {
                    jsonObj = new JSONObject(jsonStr);

                    if (jsonObj.has(Const.TAG_MESSAGES)) {
                        System.out.println(":::::::::::::has::::::::::::");
                        msgArray = jsonObj.getJSONArray(Const.TAG_MESSAGES);
                        if (msgArray != null && msgArray.length() != 0) {
                            // looping through All Contacts
                            for (int i = 0; i < msgArray.length(); i++) {
                                System.out.println("::::::::::::ARRAY:::::::::::");
                                JSONObject c = msgArray.getJSONObject(i);
                                id = c.getString("id");
                                payee_id = c.getString("payee_id");
                                payer_id = c.getString("payer_id");
                                payer_name = c.getString("payer_name");
                                payee_name = c.getString("payee_name");
                                payer_image = c.getString("payer_image");
                                payee_image = c.getString("payee_image");
                                dispute_id = c.getString("dispute_id");
                                subject = c.getString("subject");
                                message_body = c.getString("message_body");
                                added_on = c.getString("added_on");
                                sender_id = c.getString("sender_id");
                                read = c.getString("read");
                                dispute_id = c.getString(Const.TAG_DIPUTE_ID);

                                System.out.println("::::::::::::sender Id::::::::::" + sender_id + ":::::::::::::::");
                                System.out.println("::::::::::::payee ID::::::::::" + payee_id + ":::::::::::::::");
                                HashMap<String, String> disputeMsgMap = new HashMap<String, String>();

                                disputeMsgMap.put(Const.TAG_ID, id);
                                disputeMsgMap.put(Const.TAG_PAYEE_ID, payee_id);
                                disputeMsgMap.put(Const.TAG_PAYER_ID, payer_id);
                                disputeMsgMap.put(Const.TAG_PAYER_NAME, payer_name);
                                disputeMsgMap.put(Const.TAG_PAYEE_NAME, payee_name);
                                disputeMsgMap.put(Const.TAG_PAYER_IMAGE, payer_image);
                                disputeMsgMap.put(Const.TAG_PAYEE_IMAGE, payee_image);
                                disputeMsgMap.put(Const.TAG_DIPUTE_ID, dispute_id);
                                disputeMsgMap.put(Const.TAG_SUBJECT, subject);
                                disputeMsgMap.put(Const.TAG_MESSAGE_BODY, message_body);
                                disputeMsgMap.put(Const.TAG_ADDED_ON, added_on);
                                disputeMsgMap.put(Const.TAG_READ, read);
                                disputeMsgMap.put(Const.TAG_SENDER_ID, sender_id);
                                msgList.add(disputeMsgMap);

                            }
                        }

So, I want to check that "sender_Id" of JSONObjects are different or not; I just want to check weather sender_id of any object is different or all are same.

You can iterate to all of your list of HashMap before you add it to the list and then check if the current sender_id is duplicated from the last list of hashmap's sender_id

example:

//TOP CODE ARE YOURS
if(msgList.size() != 0)
{
  for(HashMap<String, String> hash :  msgList) {
     if(hash.get(sender_id) != null)
       //YOU have a duplication of id
  }
}
msgList.add(disputeMsgMap);

Thank you for help,But friend can you tell me how can i compare arrayList's element? means if all the elements are same or not?because I have "msgList" is an arrayList,SO I will compare for "sender_id"..Please tell me ..thank you

user3686229 Over a year ago

yes..."sender_id" of any object is different or all the "sender_id" are same.

Rod_Algonquin Over a year ago

@user3686229 then use the get method the way that i just did and compare all the field on the json object

user3686229 Over a year ago

if(hash.get(sender_id) != null) tells what?

Rod_Algonquin Over a year ago

@user3686229 if the current id is already in the list if hashMap
