요청시로드 및 검색 뷰를 관리하기 위해 pageloader와의 연락처 listview를 구현하려고 시도했지만 목록에서 검색 할 수는 없지만 제대로 작동하지는 않습니다. 나는 app.allContacts에있는 모든 연락처입니다. 문제는 searchview가 작동하지 않는다는 것입니다. 그리고 나는 그것의 loaderCallback 또는 searchview가 있는지 모른다.목록보기 및 LoaderCallBack이있는 Android Searchview

합니까 R.id.contacts_to가 검색보기가에서 SearchView를 사용하고 계십니까? 귀하의 XML을 게시하십시오. 또한 searchView는보기에 추가되지 않습니다. 더 많은 정보를 제공하십시오. – Libin
