  SearchView sv = FindViewById(Resource.Id.svSearchHadith);
  sv.QueryTextChange += Sv_QueryTextChange;
  lstHadiths = FindViewById<Android.Widget.ListView>(Resource.Id.lstHadiths);
  itemsHadiths = dbContext.GetAllHadiths(); // get the data in this formats List
  lstHadiths.Adapter = new ListViewHadiths(this, itemsHadiths); // adding Adapter to listview

  private void Sv_QueryTextChange(object sender, SearchView.QueryTextChangeEventArgs e)
  {
  lstHadiths.Adapter = new ListViewHadiths(this, FindInsideHadithsList(e.NewText));
  }

      private List<ModelHadiths> FindInsideHadithsList(string text)
      {
          if (text != null && text.Length > 0)
          {
              List<ModelHadiths> filteredList = new List<ModelHadiths>();
              foreach (var itm in itemsHadiths)
              {
                  if (itm != null)
                  {
                      text = text.ToLower();
                      if (itm.Description != null ? itm.Description.ToLower().Contains(text) : false ||
                          (itm.HadithType != null ? itm.HadithType.ToLower().Contains(text) : false) ||
