GridView가 유니버설 이미지 로더를 사용하여로드하지 않습니다.

Question

내 프로젝트 중 하나에 UIL을 사용하고 싶었 기 때문에이 프로토 타입 프로젝트를 통해 라이브러리 작동 방식을 확인했습니다. 샘플 프로젝트에 따라 https://github.com/nostra13/Android-Universal-Image-Loader에서 제작했습니다. 하지만 내가 proj를 실행하면 이미지가 표시되지 않고 logcat에도 오류가 표시되지 않습니다. 제목 표시 줄에 프로젝트 이름이 담긴 빈 화면이 나타납니다. 누구든지 내 코드에서 무엇이 잘못 됐는지 말해 줄 수 있습니까? 도움은 감사하게 받아 들여집니다.

그것의 당신이 당신의 onCreateView 그리드 뷰의 어댑터의 항목을 추가하는 것을 잊지 때문이다. Gridview의 어댑터를 설정 한 후에 항목을 수동으로 추가해야합니다.
