如何在 Jetpack Compose 中自定义选项卡

Question

我想在 jetpack compose 中自定义选项卡的外观，这是我的选项卡现在的样子

但我想这样查看我的标签：

我正在这样创建标签

TabRow(
        selectedTabIndex = pagerState.currentPage,
        backgroundColor = MaterialTheme.colors.primary,
        contentColor = Color.White
    ) {
        filters.forEachIndexed { index, filter ->
            Tab(
                text = {
                    Text(
                        text = filter.name.replaceFirstChar {
                            if (it.isLowerCase()) {
                                it.titlecase(Locale.getDefault())
                            } else {
                                it.toString()
                            }
                        }
                    )
                },
                selected = pagerState.currentPage == index,
                onClick = { scope.launch { pagerState.animateScrollToPage(index) } },
            )
        }
    }

我怎样才能达到那种效果，我搜索了很多但没有找到任何线索，有人可以帮忙吗？

@Composable
fun CustomTabs() {
    var selectedIndex by remember { mutableStateOf(0) }

    val list = listOf("Active", "Completed")

    TabRow(selectedTabIndex = selectedIndex,
        backgroundColor = Color(0xff1E76DA),
        modifier = Modifier
            .padding(vertical = 4.dp, horizontal = 8.dp)
            .clip(RoundedCornerShape(50))
            .padding(1.dp),
        indicator = { tabPositions: List<TabPosition> ->
            Box {}
        }
    ) {
        list.forEachIndexed { index, text ->
            val selected = selectedIndex == index
            Tab(
                modifier = if (selected) Modifier
                    .clip(RoundedCornerShape(50))
                    .background(
                        Color.White
                    )
                else Modifier
                    .clip(RoundedCornerShape(50))
                    .background(
                        Color(
                            0xff1E76DA
                        )
                    ),
                selected = selected,
                onClick = { selectedIndex = index },
                text = { Text(text = text, color = Color(0xff6FAAEE)) }
            )
        }
    }
}

效果如图gif
