How to Add Image Border in Android Jetpack Compose

Borders add a touch of refinement to your UI elements, making them stand out. In this updated tutorial, we’ll delve deeper into how to wrap an image with a border using Android Jetpack Compose.

What is Jetpack Compose?

Before we dive in, it’s good to understand what Jetpack Compose is. Jetpack Compose is Android’s modern toolkit for building native UI. It simplifies and accelerates UI development on Android.

Image with Border

The Image composable is key to displaying images on your screen. To add a border, you can use the border Modifier. Here is an example with the code.

@Composable
fun ImageExample() {
    Image(
        painter = painterResource(R.drawable.pet),
        contentDescription = null,
        contentScale = ContentScale.Crop,
        modifier = Modifier
            .size(250.dp)
            .padding(20.dp)
            .border(3.dp, Color.Red)
    )
}

We have given the thickness and color of the border using the border modifier. Like this, you can also add borders to circular images.

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            MyApplicationTheme {
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    Column {
                        ImageExample()
                    }
                }
            }
        }
    }
}

@Composable
fun ImageExample() {
        Image(
            painter = painterResource(R.drawable.pet),
            contentDescription = null,
            contentScale = ContentScale.Crop,
            modifier = Modifier
                .size(250.dp)
                .padding(20.dp)
                .border(3.dp, Color.Red)
        )
}

Output

Once you run this code, you’ll see an image of a pet with a red border. It’s a simple yet effective way to make your image pop.

Adding borders to your images in Jetpack Compose is pretty straightforward. By using the border Modifier function along with the Image composable, you can easily give your images a decorative edge.
