Android Application
11번가 검색 OPEN API 적용하기
안녕하세요
오늘은 Android Application에 11번가 검색 OPEN API를 적용해보겠습니당
저는 eclipse에서 만들었습니다.
android application project를 생성해주세요!
11번가
OPEN API 사이트입니다
http://openapi.11st.co.kr/openapi/OpenApiMain.tmall?method=getNoticeBoardList&unityBrdNo=18
로그인하셔서 OPEN API 사용 등록하시고 키 값을 받으셔야합니당
1. activity_main.xml 파일을 작성합니다.

위의 소스는 주석 처리해주시고!
imageLoader.DisplayImage(p.getProductImage(), holder.imageView);
아래부분을 작성해주시면 됩니당
위 소스를 사용하기 위해서는 4개 파일과 manafest에 소스코드추가가 필요합니다.
아래에 소스코드를 추가해놓겠습니다.
FileCache.java 작성합니다.
