title: Unable to refresh the ListView
body: <p>After i click "more" button, it suppose will extend the listview from 10 to 20.</p>
  
  <p>However after clicked, the list view did not extend and remain original size.</p>
  
  <p>It only can keep the position of scroll bar. This is half of what i need.</p>
  
  <pre><code>newsid = new int[webservice.news.size()];
          title = new String[webservice.news.size()];
          date = new String[webservice.news.size()];
          imagepath = new String[webservice.news.size()];
          for (int i = 0; i &lt; webservice.news.size(); i++) {
              newsid[i] = webservice.news.get(i).getID();
              title[i] = webservice.news.get(i).getNtitle();
              date[i] = webservice.news.get(i).getNArticalD();
              imagepath[i] = webservice.news.get(i).getImagePath();
          }
          adapter = new CustomAdapter_ParticularCategoryAllNews(this, title,
                  date, imagepath);
