Answer 1

안드로이드 어느 버전에서 작업 중이신지 모르겠지만,

혹시 Adapter getView() 에서 null을 리턴하는지 확인해 보세요.

AbsListView에서 obtainView() 함수내에서 getView() 호출 이후 null 체크 하는 코드는 없는 거 같은데, Adapter getview()에서 null 리턴이 제일 유력한 것 같네요.

정말 감사합니다!! null을 리턴하고 있었네요
정말 신기합니다 어느 오류부분을 보고 그렇게 한번에 찾으셨는지
저것들을 보고 오류를 찾는 팁좀알려주세요... 저도 나중에 누군가에게 도움이 되고싶어요

거의 최상단에 이 오류 보이시죠?
log는 위에 있을수록 나중에 찍힌겁니다. 결국
널이 떨어지기전에 어디서 떨어졌는지 log에 다 나오거든요. 위 로그 보고 판단하신거구요. 친절하게 라인수까지 다 알려주죠^^
