서버에서 xml을 요청하여
1.리스트에 뿌려줄때 전부 읽어와서 뿌려줄려니
로딩시간도 길고
속도가 너무 느리네요..
마켓에 보면 리스트를 쫙 뿌려준후
천천히 하나씩 이미지가 나오잖아요
startQuery() , onQueryComplete를 쓰면 된다고 하는데
잘 안되네요 답변 부탁드리겠습니다
그리고
2. 밑의 그림처럼 버튼으로 목록 더보기를 하니
다시 뿌려줄때 단순히 쿼리에 목록 개수를 늘려서
새로 뿌려줬더니 다시 처음으로 가네요..물론 목록은 늘어났지만요
마켓처럼 스크롤을 내리면 자동으로 추가 되면서
리스트가 늘어 나는 것은 어떻게 해야되나요?
질문이 많네요.. 답변 부탁드리겠습니다
밑에 소스 첨부 하였습니다
