添加arraylist后不允许更改hashmap值

Question

I have this arraylist and another for hashmap

 ArrayList<HashMap<String, String>> agentList = new ArrayList<HashMap<String, String>>();
 HashMap<String, String> agentproperty = new HashMap<String, String>();

I have received jArray from php file. and trying to put it in the array using hashmap.

 JSONArray jArray = jsonObj.getJSONArray(TAG_AGENT);
      String id = null;
      String name = null;

        for (int i = 0; i < jArray.length(); i++) {
            JSONObject a = jArray.getJSONObject(i);
            id = a.getString(TAG_AGENTID);
            name = a.getString(TAG_NAME);

            agentproperty.put("AGENTID", id);
            agentproperty.put("NAME", name);

            Log.d("id",id);
            Log.d("name",name);
            agentList.add(agentproperty);


    }
                Log.d("firstperson",String.valueOf(agentList.get(0)));
                Log.d("secondperson",String.valueOf(agentList.get(1)));

I can get

id 1, hame cathy; id 2, name john

for the log inside loop. But from the last log, I am getting

id 2, name john; id 2, name john It seems the value of agentproperty is changed even after adding in arraylist. I tried taking the agentList.add(agentproperty); outside of loop. Didnt work. Only inserts the last value (id 2, name john). Any idea how can i populate this array with all the values I get from loop. I will need to use agentList in listview.

Move

HashMap<String, String> agentproperty = new HashMap<String, String>();

inside the for loop
