Column composable helps to arrange child content vertically in Jetpack Compose. Sometimes, you may want to make the Column clickable to add further functionality to the mobile app. Let’s learn how to make Column clickable easily in Jetpack Compose.
In Jetpack Compose, you can make composables clickable using Modifier.clickable{}. See the following code snippet where the Column is made clickable and a Toast message is shown when the Column is clicked.
@Composable
fun ColumnExample() {
val context = LocalContext.current
Column(modifier = Modifier
.fillMaxWidth()
.height(300.dp)
.padding(40.dp)
.background(Color.Cyan).clickable {
Toast
.makeText(context, " Clickable Column Example", Toast.LENGTH_SHORT)
.show()
})
{
Text(text = "Click here to test", fontSize = 24.sp)
}
}You can also make Row clickable in the similar way.
Following is the complete code for reference.

Surface(
modifier = Modifier.fillMaxWidth(),
color = MaterialTheme.colors.background
) {
ColumnExample()
}
}
}
}
}
@Composable
fun ColumnExample() {
val context = LocalContext.current
Column(modifier = Modifier
.fillMaxWidth()
.height(300.dp)
.padding(40.dp)
.background(Color.Cyan).clickable {
Toast
.makeText(context, " Clickable Column Example", Toast.LENGTH_SHORT)
.show()
})
{
Text(text = "Click here to test", fontSize = 24.sp)
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
ComposeApplicationTheme {
ColumnExample()
}
}The output is given below.
That’s how you make Column clickable in Jetpack Compose. I hope this Android tutorial is helpful for you.
