How can I refresh my ListView using BaseAdapter

Question

I tried refresh my listview using notifyDataSetChanged() but this is marked on red. I use ListView like extended Adapter so notifyDataSetChaned it should work but is otherwise.

Below is my declaration ListView and ArrayList.

ListView listview;
ArrayList<ListData> myList = new ArrayList<>();

I set up my list in this way:

listview = (ListView) findViewById(R.id.listView);
listview.setAdapter(new MyBaseAdapter(this, myList));

I use also setOnScrollListener and I want that my listview it refresh when SROLL_STATE = 0;

    listview.setOnScrollListener(new AbsListView.OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            int position = listview.getFirstVisiblePosition();

            SCROLL_STATE = position;

            if (SCROLL_STATE == 0) {
                listview.notifyDataSetChanged();  // Here is a problem, because it's not work
            }

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {

        }
    });

Define a Adapter object, MyBaseAdapter adapter=new MyBaseAdapter(this, myList); adapter.notifyDataSetChanged();
