CursorLoaders 및 Loadermanagers를 사용하여 생각한 이점 중 하나는 커서의 수명주기를 수동으로 관리 할 필요가 없다는 것입니다. 그래서 loadermanager를 사용하여 지원 패키지를 사용하여 AutoCompleteTextView에 어댑터를 바인딩했습니다.IllegalStateException - AutocompleteTextView가있는 LoaderManager
"IllegalStateException - 이미 닫힌 개체를 다시 열려고 시도했습니다."라는 오류를 임의로 throw합니다. 우리가 로더 관리자를 사용한다면 그것은 일어나지 않을 것입니다. 잘못 될 수 있는지에

어떤 아이디어 :

다음 오류 스택입니다 : 여기
코드인가?
아직 해결 방법이 없지만 AutoCompleteTextView를 확장하고 "super"문을 둘러싼 try/catch 루프에서 onFilterComplete 오류를 포착하고 무시하고 무시했습니다. 왜 그것이 발생했는지 또는 어떻게 처리해야하는지 전혀 모른다. 문제 해결됨. 그래도 지저분 해. 좀 더 우아한 해결책을 고맙게 생각합니다. –

@BhagwadJalPark 나는이 문제를 해결했습니다. Tony가 제안한 솔루션 (OnLoadFinished에서 닫힌 상태 확인)이 나에게 효과가 없었습니다. 다음은 귀하의 통찰력에 따라 작성한 래퍼 클래스입니다. https://gist.github.com/esilverberg/5606551 – esilver
