在清單中顯示巢狀捲動項目
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
您可以在清單中顯示巢狀捲動項目,以呈現複雜的版面配置,例如產品目錄、媒體庫、新聞動態等。
版本相容性
這個實作方式需要將專案 minSDK 設為 API 級別 21 以上。
依附元件
以下程式碼會產生可雙向捲動的清單。清單的列會水平捲動;清單整體 (單一欄) 則會垂直捲動。
@Composable
fun NestedScrollingRowsList(urls: List<String>) {
LazyColumn {
items(10) {
LazyRow {
item { Text("Row: $it") }
items(urls.size) { index ->
// AsyncImage provided by Coil.
AsyncImage(
model = urls[index],
modifier = Modifier.size(150.dp),
contentDescription = null
)
}
}
}
}
}
結果
以下影片顯示在垂直捲動清單中,巢狀水平清單的結果行為。
