recyclerview not showing data from json array after 7 items

I am using Recycler View with Cardview and showing data from JSON using Volley. It works proper on targetsdkversion 19 but not showing data after 7 list items when targetsdkversion is 26.

btnsend.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
chatLayout.setVisibility(View.VISIBLE);
subject = etsub.getText().toString();
details = etdetail.getText().toString();
if (etsub.getText().toString().equals(""))
Toast.makeText(getActivity(), "Enter subject", Toast.LENGTH_SHORT).show();
subj_layout.setError("Plese Enter Subject!");

else if (etdetail.getText().toString().equals(""))
detail_layout.setError("Please Enter Details!");

else
Log.d(TAG, "onClick:send ");
String url = "http://webapi.eduware.in/test/api/ParentsCommunication?StudentCurrentID=" + studentId.trim() + "&SchoolID=" + schoolid.trim() + "&CommunicationSubject=" + subject.trim() + "&CommunicationDetails=" + details.trim();
Log.d(TAG, "onClick: " + url);
Log.d(TAG, "fetchNotificationByVolley: url = " + url);

StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
@Override
public void onResponse(String response)
Log.d(TAG, "onResponse: " + response);
try
JSONObject jobj = new JSONObject(response);
String status = jobj.getString("status");
if (status.equals("1"))
Toast.makeText(getActivity(), "Successfully added", Toast.LENGTH_SHORT).show();
getChatbyVolley();
txtnocomm.setVisibility(View.GONE);

else
Toast.makeText(getActivity(), "Data not added", Toast.LENGTH_SHORT).show();
chatLayout.setVisibility(View.VISIBLE);

catch (JSONException e)
e.printStackTrace();



, new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError error)
Log.d(TAG, "onErrorResponse: " + error.getMessage());

)
@Override
protected Map<String, String> getParams() throws AuthFailureError
return null;

;

ApplicationController.getInstance().addToRequestQueue(stringRequest);

d.dismiss();


);


As shown in image, on click of Bottom right corner Add Button One custom dialog gets open and details of that dislogs edittext will be added to recyclerview by getChatbyVolley method.I am getting succesfully added but not display in list.But if targetsdkversion is 18 then it works perfect.

private void getChatbyVolley()
chatLayout.setVisibility(View.VISIBLE);
String url = "http://webapi.eduware.in/test/api/ParentsCommunication?StudentCurrentID="+studentId.trim();
final ArrayList<Chat> arrayList = new ArrayList<>();
final ArrayList<String> array = new ArrayList<>();
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>()
@Override
public void onResponse(String response)
Log.d(TAG, "onResponse: " + response);
try
JSONObject jobj = new JSONObject(response);
String status = jobj.getString("status");
if(status.equals("1"))


JSONArray jsonArray = jobj.getJSONArray("data");

for(int i=0;i<jsonArray.length();i++)

JSONObject jsonObject = jsonArray.getJSONObject(i);
String date = jsonObject.getString("Date");
Log.d(TAG, "onResponse: "+date);
String separated = date.split("[T :]");
Log.d(TAG, "onResponse: splitted string0" + separated[0]);
Log.d(TAG, "onResponse: splitted string1" + separated[1]);
Log.d(TAG, "onResponse: splitted string2" + separated[2]);
Log.d(TAG, "onResponse: splitted string3" + separated[3]);
String time = separated[1] + ":" + separated[2];
Log.d(TAG, "onResponse: time is:::::::::::" + time);
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd");
DateFormat outputFormat = new SimpleDateFormat("dd MMM yyyy");
String inputDateStr=separated[0];
Date date1 = inputFormat.parse(inputDateStr);
String outputDateStr = outputFormat.format(date1);
String detail = jsonObject.getString("CommunicationDetails");
Log.d(TAG, "onResponse: details========="+detail);
String pid = jsonObject.getString("ParentID");
Log.d(TAG, "onResponse: pid is*********"+pid);
array.add(pid);
Log.d(TAG, "onResponse: pid is*********"+array);
editor.putString("parent_id",pid);
editor.putString("parentid_array",array.toString());
editor.commit();
Chat c = new Chat();
c.setCommsubject(jsonObject.getString("CommunicationSubject"));
c.setCommdetails(jsonObject.getString("CommunicationDetails"));
c.setDate(outputDateStr);
c.setParentid(pid);
arrayList.add(c);
progress.dismiss();


chatAdapter = new ChatAdapter(getActivity(), arrayList);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
recyclerView.setAdapter(chatAdapter);
recyclerView.setHasFixedSize(true);
chatAdapter.notifyDataSetChanged();

Log.d(TAG, "onResponse: " + arrayList.size());
progress.dismiss();

else

Toast.makeText(context, "No communication available", Toast.LENGTH_SHORT).show();
progress.dismiss();
rlnocomm.setVisibility(View.VISIBLE);
btnadd.setVisibility(View.VISIBLE);

catch (JSONException e)
e.printStackTrace();
catch (ParseException e)
e.printStackTrace();



, new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError error)
Log.d(TAG, "onErrorResponse: " + error.getMessage());

)
@Override
protected Map<String, String> getParams() throws AuthFailureError
return null;

;
ApplicationController.getInstance().addToRequestQueue(stringRequest);

Add this following line in your code. It works for me

recyclerview.setHasFixedSize(true);
