Jetpack Compose Column Composable Alignment-CodePudding

I'm creating a layout with Jetpack Compose and there is a column. I would like center one composable and the other to align to the bottom. Here is an image of my target screen

CodePudding user response：

Use a Column with weight(1f) and verticalArrangement = Arrangement.Center to wrap the first item. Here's the code

@Composable
fun Demo() {
    Column(modifier = Modifier.fillMaxSize()) {
        Column(
            modifier = Modifier
                .fillMaxWidth()
                .weight(1f)
                .background(color = Color.Transparent),
            verticalArrangement = Arrangement.Center,
        ) {
            Box(
                modifier = Modifier
                    .fillMaxWidth()
                    .height(100.dp)
                    .padding(15.dp)
                    .background(color = Color.Green)
            )
        }


        Box(
            modifier = Modifier
                .fillMaxWidth()
                .height(60.dp)
                .background(color = Color.Yellow)
        )
    }
}

@Composable
@Preview
fun DemoPreview() {
    Demo()
}
