如何在 Android Jetpack Compose 中制作圆形底部导航

Question

我想在 Android Jetpack compose 中做一个底部导航，但在我找到的每个源中，用 compose 构建的导航是正常的，扁平的像这样，

重点是我找不到制作这样东西的方法

我怎样才能只做一件事？谢谢

Answer 1

使用clip和RoundedCornerShap:

var selectedItem by remember { mutableStateOf(0) }
val items = listOf("Songs", "Artists", "Playlists")

Box(modifier = Modifier.fillMaxSize(), contentAlignment = Alignment.BottomStart) {
    BottomNavigation(modifier = Modifier.clip(shape = RoundedCornerShape(topStart = 20.dp, topEnd = 20.dp))) {
        items.forEachIndexed { index, item ->
            BottomNavigationItem(
                icon = { Icon(Icons.Filled.Favorite, contentDescription = null) },
                label = { Text(item) },
                selected = selectedItem == index,
                onClick = { selectedItem = index }
            )
        }
    }
}

只需使用 clip Modifier 并在顶角添加 RoundedCornerShape ，这里是示例代码

BottomNavigation(
            backgroundColor = colorResource(id = R.color.black),
            modifier = Modifier.fillMaxWidth().clip(RoundedCornerShape(15.dp, 15.dp, 0.dp, 0.dp))
        )
