Buttons are one of the most important UI components for mobile app development. Buttons always have solid colors as the background. But sometimes, developers want to have a transparent background. In this Jetpack Compose tutorial, let’s learn how to show a button with transparent background.
We have to change the backgroundColor to make the Button transparent. Compose already has a color named transparent and we can use it for the desired output.
@Composable
fun TransparentButtonExample() {
Box() {
Button(onClick = { println("Button Clicked!") },
modifier = Modifier.align(Alignment.Center),
colors = ButtonDefaults.buttonColors(backgroundColor = Color.Transparent)) {
Text(text = "Transparent Button")
}
}
}You will get the following output.
Following is the complete code for reference.
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.*
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.Alignment
import androidx.compose.ui.tooling.preview.Preview
import com.example.myapplication.ui.theme.MyApplicationTheme
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApplicationTheme {
Surface(
color = MaterialTheme.colors.background,
modifier = Modifier.fillMaxSize()
) {
TransparentButtonExample()
}
}
}
}
}
@Composable
fun TransparentButtonExample() {
Box() {
Button(onClick = { println("Button Clicked!") },
modifier = Modifier.align(Alignment.Center),
colors = ButtonDefaults.buttonColors(backgroundColor = Color.Transparent)) {
Text(text = "Transparent Button")
}
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
MyApplicationTheme {
TransparentButtonExample()
}
}That’s how you add a transparent button in Jetpack Compose.
