Android '상단 시트'는 '하단 시트'와 동일합니까?

Question

"하단 시트"유형의 레이아웃을 구현하고 싶지만 "하단"시트가 위/아래 드래그 가능보기로는 잘 작동하지 않는 MapFragment가되는 비틀기가 있습니다.

로직을 "Top Sheet"디자인으로 "뒤집어"Top Sheet를 위로/아래로 드래그하여 아래쪽 MapFragment를 더 많거나 적게 표시하는 것은 당연한 생각이었습니다.

예 :

...이에서 ...이 [같은]에 ...

는 지원 디자인 도구 제공이 가능, 또는 내가 가진 것 혼자서 이렇게 굴리는거야?

Answer 1

여기 내가 위에 언급 한 내 솔루션의 기초입니다. 나는 나중에 그것을 다시 살릴거야.
