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) {
Divider(thickness = 1.dp, color = Color.Black)
}
}The output will be as given below.
Following is the complete code.
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.Alignment
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() {
Column(horizontalAlignment = Alignment.CenterHorizontally,verticalArrangement = Arrangement.Center) {
Divider(thickness = 1.dp, color = Color.Black)
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
MyApplicationTheme {
Example()
}
}That’s how you draw horizontal lines in Jetpack Compose.
