이 RelativeLayout은 확장 버튼을 클릭하면 축소됩니다. 버튼 하나로 잘 작동합니다. 동일한 레이아웃에서 더 많은 두 개의 RelativeLayout 에 동일한 메소드를 재사용하고 다른 두 개의 버튼을 사용하여 확장하고 싶습니다.확장 및 축소 단추로 클릭하여 relativelayout을 클릭하십시오.
이 코드는 정상적으로 실행되고 있습니다. 동일한 작업을 수행하기 위해 더 많은 레이아웃을 원할뿐입니다.
레이아웃 : 이것은 내 코드입니다

안녕하세요, 고마워요. 하지만 처음에는 숨길 수 있도록 VISibility (View.GONE)를 설정하는 방법. – feltonjk
@feltonjk 최근 코멘트 (삭제)가 잘못되었습니다. XML 설정에서 android : visibility = "gone" – Cheticamp
하지만 set android : visibility = "gone"을 설정하면 작동하지 않고 아무것도 표시되지 않습니다. 나 또한 relativeLayout.setVisibility (View.GONE) 너무 노력하고 그 시도했다.다른 soluton 말해 줄 수 있습니까? – feltonjk
