지연 로드 그리드를 사용하여 대용량 데이터 세트와 동적 콘텐츠를 관리하여 앱 성능을 개선할 수 있습니다. 지연 그리드 컴포저블을 사용하면 여러 열 또는 행에 걸쳐 스크롤 가능한 컨테이너에 항목을 표시할 수 있습니다.
버전 호환성
이 구현을 사용하려면 프로젝트 minSDK를 API 수준 21 이상으로 설정해야 합니다.
종속 항목
그리드 방향 결정
LazyHorizontalGrid 및 LazyVerticalGrid 컴포저블은 그리드에 항목을 표시하도록 지원합니다. 지연 세로 그리드는 여러 열에 걸쳐 세로로 스크롤 가능한 컨테이너에 항목을 표시하는 반면, 지연 가로 그리드는 가로축을 중심으로 동일하게 동작합니다.
스크롤 가능한 그리드 만들기
다음 코드는 3개의 열이 있는 가로 스크롤 그리드를 만듭니다.
@ComposablefunScrollingGrid(){valitemsList=(0..15).toList()valitemModifier=Modifier.border(1.dp,Color.Blue).width(80.dp).wrapContentSize()LazyHorizontalGrid(rows=GridCells.Fixed(3),horizontalArrangement=Arrangement.spacedBy(16.dp),verticalArrangement=Arrangement.spacedBy(16.dp)){items(itemsList){Text("Item is $it",itemModifier)}item{Text("Single item",itemModifier)}}}
