Lines are helpful to divide different UI elements of mobile apps. In this simple and short Jetpack Compose tutorial let’s learn how to add a vertical line.
You can use Divider from Jetpack Compose to draw lines- horizontal or vertical. Wrapping a Divider with Row makes the line vertical. See the code snippet given below.
@Composable
fun Example() {
Row(
horizontalArrangement = Arrangement.Center
) {
Divider(modifier = Modifier.fillMaxHeight().width(1.dp), color = Color.Black)
}
}Following is the output.
Following is the complete code of this Jetpack Compose example to show vertical line.
package com.example.myapplication
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.*
import androidx.compose.material.*
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.tooling.preview.Preview
import androidx.compose.ui.unit.dp
import com.example.myapplication.ui.theme.MyApplicationTheme
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApplicationTheme {
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.background
) {
Example()
}
}
}
}
}
@Composable
fun Example() {
Row(
horizontalArrangement = Arrangement.Center
) {
Divider(modifier = Modifier.fillMaxHeight().width(1.dp), color = Color.Black)
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
MyApplicationTheme {
Example()
}
