fragment간의 화면 전환 질문 [closed]

Question

제가 프래그먼트로 작업중인데요

A fragment화면에서 B fragment화면으로 이동했을때에 Afragment화면에서 있던 버튼이

 B fragment화면에 출력이되는데 어떻게 해야되나요?

 

Answer 1

레이아웃코드를 봐야 정확히 알겠는데요.
아마 프래그먼트를 add로 하셔서 그 뒤에있는게 표시되는게 아닐까싶은데, replace로 하시거나,
 b 프래그먼트의 최상단 레이아웃에 background 색지정, clickable true focusable true 지정해보셔요
