Is it normal that AdapterList is overlap with Button? And, when I try to click Button more than 20 times, VerticalScroller is fine. But, in AdapterList, my app is stopped with java.lang.IndexOutOfBoundsException: Index: 8, Size: 8. And whatever the numbers are, it just says Index: 8, Size: 8. Plese someone correct my code. Thank you.

I see it when I scroll quickly and exit the activity right after scrolling. Here's the code

Copy code

AdapterList(data = personList) { person ->
        Row(modifier = LayoutWidth.Fill + LayoutPadding(16.dp)) {
            Card(shape = RoundedCornerShape(4.dp), color = Color.Black, modifier = LayoutWidth.Fill) {
                Text(
                    person.name, style = TextStyle(
                        color = Color.White,
                        fontSize = 20.sp,
                        textAlign = TextAlign.Center
                    ), modifier = LayoutPadding(16.dp)
                )
            }
        }
    }

looks like a bug in adapterlist. i’m not sure if it’s known issue or not, but the author will probably see this thread soon and let you know 🙂 if not, i’ll ping him about it tomorrow
