jsoup으로 JTBC 뉴스 RSS 읽어오는 예제 - 코드 전체보기 [Android]

JTBC의 RSS 서비스 링크

http://news.jtbc.joins.com/Etc/RssService.aspx

<RSS 서비스 메인>

<속보 RSS xml>

Jsoup을 이용해 rss 서비스 주소와 이름을 가져오고 이걸로 안드로이드에 Tab layout(탭)으로 만든다

원하는 메뉴(속보, 정치, 경제, 사회, 국제, 문화, 연예, 스포츠, 풀영상, 뉴스랭킹, 뉴스룸, 아침&, 뉴스현장, 정치부회의)를 누르면

해당 서비스 주소에 나오는 뉴스를 ListView(리스트)로 보여준다
