    //to fetch data we do string request
    StringRequest stringRequest = new StringRequest(Request.Method.GET,
            URL_Data,
            new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            try {
                //JSONObject jsonObject=new JSONObject(s);
               // JSONArray array=jsonObject.getJSONArray("contact");//Array name

                //converting the string to json array object

                JSONArray array = new JSONArray(response);
                //JSONArray arr=array.getJSONArray("Array");

                for(int i=0;i< array.length();i++){
                    //getting product object from json array

                    JSONObject jsonObjec = array.getJSONObject(i);

                    ListUser user=new ListUser(

anyone try to help

Answer 1

Try this after setting your adapter use MobileProgressBar.setVisibility(View.GONE);

 adapter=new MyAdapter(listUsers, getApplicationContext());//data from 
 MyAdapter constructorrecyclerView.setAdapter(adapter);
 MobileProgressBar.setVisibility(View.GONE);

Answer 2

set visibility gone in onResponse and onErrorResponse

private void loadRecyclerViewData(){

    //to fetch data we do string request
    StringRequest stringRequest = new StringRequest(Request.Method.GET,
            URL_Data,
            new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {

            try {
                //JSONObject jsonObject=new JSONObject(s);
               // JSONArray array=jsonObject.getJSONArray("contact");//Array name

                //converting the string to json array object

                JSONArray array = new JSONArray(response);
                //JSONArray arr=array.getJSONArray("Array");

                for(int i=0;i< array.length();i++){
                    //getting product object from json array

                    JSONObject jsonObjec = array.getJSONObject(i);

                    ListUser user=new ListUser(
                            jsonObjec.getString("name"),
                            jsonObjec.getString("email"),
                            jsonObjec.getString("contactno"),
                            jsonObjec.getString("date"),
                            jsonObjec.getString("time"),
                            jsonObjec.getString("requirement_type"),
                            jsonObjec.getString("message")

                    );

                            listUsers.add(user);

                }



               adapter=new MyAdapter(listUsers, getApplicationContext());//data from MyAdapter constructor
                recyclerView.setAdapter(adapter);
               MobileProgressBar.setVisibility(View.GONE);//change here

            }

            catch (JSONException e) {
                e.printStackTrace();
                MobileProgressBar.setVisibility(View.GONE);//change here
            }
        }
    },

            new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError  volleyError) {
            MobileProgressBar.setVisibility(View.GONE);//change here
            Toast.makeText(getApplicationContext(), volleyError.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

    RequestQueue requestQueue= Volley.newRequestQueue(this);

    requestQueue.add(stringRequest);

}

                        );

                                listUsers.add(user);

                }

                catch (JSONException e) {

Just use,

MobileProgressBar.setVisibility(View.GONE);

when you want to stop progress bar.
