The Row is an important composable and its significance in building layouts is very high. It helps to arrange child elements horizontally. Sometimes, app developers want to make Row clickable in Jetpack Compose.
Modifier.clickable is used to make Row composable clickable. In the following code snippet, when the Row is clicked a Toast message is shown.
@Composable
fun RowExample() {
val context = LocalContext.current
Row(modifier = Modifier
.fillMaxWidth()
.height(200.dp)
.padding(20.dp)
.background(Color.Cyan).clickable {
Toast
.makeText(context, " Clickable Row Example", Toast.LENGTH_SHORT)
.show()
})
{
Text(text = "Click here to test", fontSize = 24.sp)
}
}Following is the output.
Likewise, you can also make Column clickable.
Following is the complete code for reference.

class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
ComposeApplicationTheme {
Surface(
modifier = Modifier.fillMaxWidth(),
color = MaterialTheme.colors.background
) {
RowExample()
}
}
}
}
}
@Composable
fun RowExample() {
val context = LocalContext.current
Row(modifier = Modifier
.fillMaxWidth()
.height(200.dp)
.padding(20.dp)
.background(Color.Cyan).clickable {
Toast
.makeText(context, " Clickable Row Example", Toast.LENGTH_SHORT)
.show()
})
{
Text(text = "Click here to test", fontSize = 24.sp)
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
ComposeApplicationTheme {
RowExample()
}
}That’s how you make Row clickable in Jetpack Compose. I hope this Android tutorial is helpful for you.
