Showing Alert Dialog with compose example android

 With new compose library you can show alert dialog using the android compose below is the example :

@Composable
fun showDialog(message: String, onDismiss: () -> Unit) {
    AlertDialog(
        text = { Text(message) },
        onDismissRequest = onDismiss,
        buttons = {
            Column {
                Divider(
                    androidx.compose.ui.Modifier.padding(horizontal = 12.dp),
                    color = MaterialTheme.colors.onSurface.copy(alpha = 0.2f)
                )
                Column {
                    TextButton(
                        onClick = onDismiss,
                        shape = RectangleShape,
                        contentPadding = PaddingValues(16.dp),
                        modifier = androidx.compose.ui.Modifier.fillMaxWidth(),
                    ) {
                        Text("Yes")
                    }
                    TextButton(
                        onClick = onDismiss,
                        shape = RectangleShape,
                        contentPadding = PaddingValues(16.dp),
                        modifier = androidx.compose.ui.Modifier.fillMaxWidth()
                    ) {
                        Text("No")
                    }
                }
            }
        }
    )
}

above example we are using column because we want to show 2 buttons vertically.

to execute above method you can call like this. 

showDialog("Sample Text\n\nSample Text\n\nSample Text", onDismiss = {

})

If you want to show 2 buttons horizontally with equal split you can use Row and modifier property with weight with something like this :

@Composable
fun showDialog(message: String, onDismiss: () -> Unit) {
    AlertDialog(
        text = { Text(message) },
        onDismissRequest = onDismiss,
        buttons = {
            Column {
                Divider(
                    androidx.compose.ui.Modifier.padding(horizontal = 12.dp),
                    color = MaterialTheme.colors.onSurface.copy(alpha = 0.2f)
                )
                Row {
                    TextButton(
                        onClick = onDismiss,
                        shape = RectangleShape,
                        contentPadding = PaddingValues(16.dp),
                        modifier = androidx.compose.ui.Modifier.weight(1.0f, true),
                    ) {
                        Text("Yes")
                    }
                    TextButton(
                        onClick = onDismiss,
                        shape = RectangleShape,
                        contentPadding = PaddingValues(16.dp),
                        modifier = androidx.compose.ui.Modifier.weight(1.0f, true),
                    ) {
                        Text("No")
                    }
                }
            }
        }
    )
}
