滚动后为什么文本会在listview中显示？

Question

下面是我的日历日视图适配器。现在我希望数据来自服务器，但是当我滚动listview时它显示。我希望在活动启动时滚动显示数据。我怎样才能做到这一点？

public class SearchListAdapter extends BaseAdapter {
        private Activity activity;
        private LayoutInflater inflater;
        private List<Details> movieItems;

        public SearchListAdapter(Activity activity, List<Details> movieItems) {
            this.activity = activity;
            this.movieItems = movieItems;
        }

        @Override
        public int getCount() {
            return HOURS_PER_DAY;
        }

        @Override
        public Object getItem(int location) {
            return movieItems.get(location);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(final int position, View convertView, ViewGroup parent) {

            LayoutInflater inflater = getLayoutInflater();
            convertView = (View) inflater.inflate(R.layout.list_item_appointment, listView, false);

            TextView hourTV = (TextView) convertView.findViewById(R.id.hourTV);

            if (val < 10) {
