안드로이드 새로고침 + Android SwipeRefresh

안드로이드 새로고침

PullToRefresh 라이브러리를 여러 가지가 많이 있다.

커스텀 마이징 하기 귀찮고 간편하게 쓰고 싶다면 SwipeRefresh를 쓰면 된다. 편하자나~

아래 API 설명참고

http://developer.android.com/intl/ko/reference/android/support/v4/widget/SwipeRefreshLayout.html

먼저 스크린샷을 보면 ListView 안에 11,22,33,44 가 담겨있음~

이벤트 액션을 위에서 아래로 당기면 아래와 같은 동글 뱅어가 나옵니다.

3초동안 돌리고 Refresh 된 모습

이런 모양이 나오게 되는 거조!

자세한건 아래 소스를 참고하시길
