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); lv.addFooterView(footermore); if (constant.isOnline()) { lv.addFooterView(constant.AdMob()); } TextView titletext = (TextView) findViewById(R.id.text_pagetitle); titletext.setText(pagetitletext.toString()); lv.setAdapter(adapter); </code></pre> <p>This is call when launch activity.</p> <pre><code>btnmore.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { 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.setTitle(title); adapter.setDate(date); adapter.setImagepath(imagepath); position = lv.getFirstVisiblePosition(); lv.smoothScrollToPosition(position); adapter.notifyDataSetChanged(); </code></pre> <p>This is what i call after i click "more button".
