Borders can make your UI elements distinct and beautiful. Let’s learn how to show a border around the image in this Android Jetpack Compose tutorial.
Image composable helps to display images and you can add border with the Modifier. See the code snippet given below.
@Composable
fun BorderImage() {
Column() {
Image(
painter = painterResource(R.drawable.woman),
contentDescription = "Image with Border",
contentScale = ContentScale.Crop,
modifier = Modifier
.size(250.dp)
.border(3.dp, Color.Red)
)
}
}Following is the complete code.
package com.example.example
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.Image
import androidx.compose.foundation.border
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.layout.size
import androidx.compose.material.*
import androidx.compose.runtime.*
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.layout.ContentScale
import androidx.compose.ui.res.painterResource
import androidx.compose.ui.tooling.preview.Preview
import androidx.compose.ui.unit.dp
import com.example.example.ui.theme.ExampleTheme
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
ExampleTheme {
// A surface container using the 'background' color from the theme
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.background
) {
BorderImage()
}
}
}
}
}
@Preview(showBackground = true)
@Composable
fun BorderImage() {
Column() {
Image(
painter = painterResource(R.drawable.woman),
contentDescription = "Image with Border",
contentScale = ContentScale.Crop,
modifier = Modifier
.size(250.dp)
.border(3.dp, Color.Red)
)
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
ExampleTheme {
BorderImage()
}
}Following is the output.
That’s how you add borders to an image in Jetpack Compose.
