    View rootView =  inflater.inflate(R.layout.fragment_main, container, false);
    recyclerView = rootView.findViewById(R.id.recyclerview);
    list = new ArrayList<>();
    Button send= rootView.findViewById(R.id.button);
    final EditText editText = rootView.findViewById(R.id.editText);
    send.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            list.add(0,editText.getText().toString());
            recycleAdapter.notifyDataSetChanged();

        }
    });
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayout.VERTICAL,true));
    recycleAdapter = new RecycleAdapter(getActivity(), list);
