With compose

Remember to add dependencies to build.gradle:

implementation ‘androidx.constraintlayout:constraintlayout-compose:1.0.0-beta02’

In your activity

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            ShapeImageApplicationTheme {
                Surface(color = MaterialTheme.colors.background) {
                    RoundedCornerShapeDemo()
                }
            }
        }
    }
}

@Composable
fun RoundedCornerShapeDemo() {
    ImageResource(shape = RoundedCornerShape(10.dp))
}

@Composable
fun ImageResource(shape: Shape) {
    ConstraintLayout(modifier = Modifier.fillMaxSize()) {
        val (redBox, imageBox) = createRefs()
        Box(
            modifier = Modifier
                .size(100.dp)
                .clip(shape)
                .background(Color.Red)
                .constrainAs(redBox) {})

        val image: Painter = painterResource(id = R.drawable.ic_launcher_background)
        Image(painter = image, contentDescription = "", modifier = Modifier
            .size(90.dp)
            .clip(shape)
            .constrainAs(imageBox) {
                top.linkTo(redBox.top)
                start.linkTo(redBox.start)
                end.linkTo(redBox.end)
                bottom.linkTo(redBox.bottom)
            })
    }
}

@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
    ShapeImageApplicationTheme {
        RoundedCornerShapeDemo()
    }
}
