How to add Horizontal Line in Android Jetpack Compose

Jetpack Compose is the preferred way to build the UI of your native Android app. In this Jetpack Compose tutorial, let’s learn how to show a horizontal line easily.

Jetpack Compose has Divider, which is basically a line that divides the space between elements. Placing a Divider inside the Column helps you to show a horizontal line. See the code snippet given below.

@Composable
    fun Example() {
        Column(horizontalAlignment = Alignment.CenterHorizontally,verticalArrangement = Arrangement.Center,
            modifier = Modifier.fillMaxSize()
            ) {
            Divider(thickness = 1.dp, color = Color.Black)
        }
    }

The output will be as given below.

Following is the complete code.

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


    @Composable
    fun Example() {
        Column(horizontalAlignment = Alignment.CenterHorizontally,verticalArrangement = Arrangement.Center,
            modifier = Modifier.fillMaxSize()
            ) {

        }
