Android : How to implement AmazingListview using Filter concept

public void filter(String charText)
{
    searchProList.clear();
    try
    {
        for (ProductItem wp : searchproductList)
        {
            if (wp.getProduct_name().toLowerCase(Locale.getDefault()).contains(charText.toLowerCase()))
            {
                searchProList.add(wp); /*
                                         * adapter=new
                                         * SectionComposerAdapter
                                         * (getActivity(),searchProList);
                                         */
                for (int p = 0; p < searchProList.size(); p++)
                {
                    String se = searchProList.get(p).getProduct_name();
                    String idd = searchProList.get(p).getProduct_id();
                    String price = searchProList.get(p).getProduct_reg_pri();
                    System.out.println("search list1=====" + se);
                    System.out.println("search list price=====" + price);
                }
            }
        }
        adapter.notifyDataSetChanged();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}
