이미지가있는 필터 목록보기

Question

나는 내 자신의 사용자 지정 ListView 어댑터를 만들었으므로 어떤 항목을 필터링하려고 시도했는데 어떻게 할 수 있는지 설명했습니다. 표준 어댑터에서 쉽게 그래서 난이 tryied하지만이 작동하지 않습니다

     adaptor = new ImageAndTextAdapter(getApplicationContext(),R.layout.customlist,items); 
     setListAdapter(adaptor); 


    }

     } 

     @Override

    public void testnow(View V)

     adaptor.getFilter().filter("ipsum"); 
     adaptor.notifyDataSetChanged(); 
     getListView().refreshDrawableState(); 

    } 

}
