Question

있어 코드 : Coverflow

나는 완료, 수직 하나를 만드는 데 필요한 것을, 하지만, 너무 (I를 메모리 문제가를 몇 가지 방법이 있지만 전체 방법은 동일을 변경하여 안드로이드 2.2에서 구축 중이다.). 드로어 블에서 이미지를 사용해야합니다. 어떤 사람이이 샘플을 사용했다면, 메모리 문제를 어떻게 관리했는지 말해 주실 수 있습니까?

주요 클래스는 이것이다 :

<com.example.coverflow.CoverFlow 
android:id="@+id/coverflow" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
/> 

내가 유 따라 패키지 이름을 변경하지 않은 생각합니다.
