我一直在努力使它，使第一个项目上的一个LazyRow是居中的屏幕中间，只要打开应用程序。对齐行为在滚动时起作用，但当应用最初打开时，第一个项目不在页面的中心。

LazyRow支持snapper和无限滚动

@OptIn(ExperimentalSnapperApi::class)
@Composable
fun CircularList(
    data: List<SingleBox>,
    modifier: Modifier = Modifier,
    isEndless: Boolean = true
) {
    val listState = rememberLazyListState(
        if (isEndless) Int.MAX_VALUE / 2 else 0
    )

val configuration = LocalConfiguration.current

val screenWidth = configuration.screenWidthDp.dp
val contentPadding = PaddingValues(horizontal = screenWidth / 2) //This moves starting point of item horizontally
BoxWithConstraints {
    LazyRow(
        state = listState,
        modifier = modifier,
        contentPadding = contentPadding,
        flingBehavior = rememberSnapperFlingBehavior(listState, SnapOffsets.Center, snapIndex = { _, startIndex, targetIndex ->
            targetIndex.coerceIn(startIndex - 7, startIndex + 7) //This snaps item to center of page when LazyRow stops moving
        })

    )
    {
        items(
            count = if (isEndless) Int.MAX_VALUE else data.size, //This makes it scroll infinitly
            itemContent = {
                val index = it % data.size
                CustomItem(data[index])    // item composable
            },

        )
    }

}

}
