API Demo에 있는 ExpandableList1예제를 참고해 만들었는데, 계속 indicator와 간격이 이상하네요.

혹시나 소스에 문제가 있나해서 API demo소스를 그대로 copy&paste해서 돌려보았더니 그래도 이상하네요.

indicator 이미지를 리소스로 저장하는것과 selector 지정하는 것도 동일하게 해줬는데, 다음과 같은 차이가 나는 이유를 모르겠네요.

왼쪽이 제가 따로 프로젝트를 만들어서 돌린것이고, 오른쪽이 API demo 창입니다.

리소스도 동일하고 소스도 동일한데, 왜 이런 차이가 나는지 모르겠네요.

혹시나 모르니 제가 따로 프로젝트 만든거 소스를 첨부할께요
