      public FinderListAdapter(Context paramContext, List&lt;String&gt;paramList)

          this.context = paramContext;
          this.options = paramList;
          this.inflater = LayoutInflater.from(paramContext);
      }
  
      @Override
      public int getCount() 
      {
          return this.options.size();
