navigationDrawer의 listView에는 항목 1, 항목 2 및 항목 3이 있습니다. item1에는 두 개의 버튼 (활성화 및 비활성화)이 있습니다. 사용자가 item1을 클릭 한 다음 레이아웃에서 해당 사용 단추를 클릭하면 navigationdrawer의 목록보기에있는 다른 두 항목이 나타납니다. 그리고 사용자가 비활성화 버튼을 클릭하면 (item2 및 item3)이 나타나면 사라져야합니다.동일한 목록의 항목에서 실행 된 작업을 기반으로 목록보기 항목을 사용/사용 중지하는 방법보기
현재 에 머물렀고 item1 layout에 글을 올렸는데 item1 레이아웃의 button listener 안에 무엇을 써야할지 모르겠습니다. 친절하게 임대해라.
이하는 내 시도이며,이 단계를 수행하는 데 도움과 안내가 필요합니다.
