Adaptive Layouts with Jetpack Compose

Today, I want to delve into an essential aspect of modern Android development: Adaptive Layouts with Jetpack Compose. As we build for a diverse range of devices, ensuring a seamless and responsive user experience is crucial.

What are Adaptive Layouts?

Adaptive layouts dynamically adjust to different screen sizes and orientations, providing an optimized user experience on various devices, from phones to tablets to foldable.

Why Jetpack Compose?

Jetpack Compose simplifies creating adaptive layouts with its powerful and flexible APIs. Here’s why it stands out:

1. Declarative Syntax: Easily define UI components that adapt to screen changes.
2. Flexibility: Seamlessly manage different layouts for different device configurations.
3. Efficiency: Write less code and achieve more with Compose’s concise syntax.

Key Concepts

ConstraintLayout

ConstraintLayout in Compose allows you to create complex layouts with a flat view hierarchy. It’s perfect for adaptive designs.

@Composable
fun AdaptiveLayout() {
    ConstraintLayout {
        val (text, image) = createRefs()

        Text(
            text = "Hello, Compose!",
            modifier = Modifier.constrainAs(text) {
                top.linkTo(parent.top)
                start.linkTo(parent.start)
            }
        )

        Image(
            painter = painterResource(id = R.drawable.sample),
            contentDescription = null,
            modifier = Modifier.constrainAs(image) {
                top.linkTo(text.bottom)
                start.linkTo(parent.start)
            }
        )
    }
}

BoxWithConstraints

BoxWithConstraints gives you the dimensions of its constraints, allowing you to adjust the layout based on the available space.

@Composable
fun ResponsiveBox() {
    BoxWithConstraints {
        if (maxWidth < 600.dp) {
            // Layout for small screens
            Column {
                Text("Small Screen")
                // other components
            }
        } else {
            // Layout for large screens
            Row {
                Text("Large Screen")
                // other components
            }
        }
    }
}

Real-World Application

Example: Adaptive Card Layout

Here’s a practical example of an adaptive card layout that adjusts based on screen size:

@Composable
fun AdaptiveCard() {
    BoxWithConstraints {
        if (maxWidth < 600.dp) {
            Column {
                CardContent()
            }
        } else {
            Row {
                CardContent()
            }
        }
    }
}

@Composable
fun CardContent() {
    Card {
        Column {
            Text("Title")
            Spacer(modifier = Modifier.height(8.dp))
            Text("Description")
        }
    }
}

Final Thoughts
