LazyRow¶

A LazyRow is a horizontal scrolling list that only composes and lays out the currently visible items. It’s similar to a horizontal Recyclerview in the classic Android View system.

@Composable
fun LazyRowDemo() {
    val list = listOf(
        "A", "B", "C", "D"
    ) + ((0..100).map { it.toString() })
    LazyRow(modifier = Modifier.fillMaxHeight()) {
        items(items = list, itemContent = { item ->
            Log.d("COMPOSE", "This get rendered $item")
            when (item) {
                "A" -> {
                    Text(text = item, style = TextStyle(fontSize = 80.sp))
                }
                "B" -> {
                    Button(onClick = {}) {
                        Text(text = item, style = TextStyle(fontSize = 80.sp))
                    }
                }
                "C" -> {
                    //Do Nothing
                }
                "D" -> {
                    Text(text = item)
                }
                else -> {
                    Text(text = item, style = TextStyle(fontSize = 80.sp))
                }
            }
        })
    }
}
