HelpFragment에서 viewpager 기능을 사용하여 이미지를 보여주려하는데요
처음 진입시에는 잘 동작하지만 다른 fragment로 이동하여 재진입하게 되면 이미지를 띄우지 않는 페이지가 발생합니다
HelpFragment는 navigationdrawer 를 이용하여 환경 설정 fragment 진입 후 리스트 클릭 시 불려지는 fragment 입니다
또한 navigationdrawer 메뉴 아이콘을 < up아이콘으로 바꾸는게 setDisplayHomeAsUpEnabled(true) 함수로 알고 있는데
함수를 호출하여도 그대로 메뉴 아이콘으로 남아있습니다
이 두가지가 해결이 안되고 있어 힘드네요...ㅠㅠ 고수분들의 조언 부탁 드립니다
