Button Long Press Listener in Android jetpack compose

Question

I am having a Android Composable UI with a Button. How can I track Button Long Press events? I got it working for "Text" Long press, but for Button It is not working. Same way like below if I apply modifier to button, it is not working.

Text(
                        text = view.text,
                        fontSize = view.textFontSize.toInt().sp,
                        fontWeight = FontWeight(view.textFontWeight.toInt()),
                        color = Color(android.graphics.Color.parseColor(view.textColor)),
                        modifier = Modifier.clickable(onClick = {
                                println("Single Click")
                            }, onLongClick = {
                                println("Long Click")
                            }, onDoubleClick = {
                                println("Double Tap")
                     })
                )

The best way to handle this is to roll your own Button. The Material Button is basically just a Surface and a Row. The reason adding your own Modifier.clickable doesn't work is because one is already set.

So, if you'd like to add onLongPress, etc you can copy/paste the default implementation and pass those lambdas in.

@Composable
@OptIn(ExperimentalMaterialApi::class, ExperimentalFoundationApi::class)
fun Button(
    onClick: () -> Unit,
    modifier: Modifier = Modifier,
    onLongClick: (() -> Unit)? = null,
    onDoubleClick: (() -> Unit)? = null,
    enabled: Boolean = true,
    interactionState: InteractionState = remember { InteractionState() },
    elevation: ButtonElevation? = ButtonDefaults.elevation(),
    shape: Shape = MaterialTheme.shapes.small,
    border: BorderStroke? = null,
    colors: ButtonColors = ButtonDefaults.buttonColors(),
    contentPadding: PaddingValues = ButtonDefaults.ContentPadding,
    content: @Composable RowScope.() -> Unit
) {
    val contentColor by colors.contentColor(enabled)
    Surface(
        shape = shape,
        color = colors.backgroundColor(enabled).value,
        contentColor = contentColor.copy(alpha = 1f),
        border = border,
        elevation = elevation?.elevation(enabled, interactionState)?.value ?: 0.dp,
        modifier = modifier.combinedClickable(
            onClick = onClick,
            onDoubleClick = onDoubleClick,
            onLongClick = onLongClick,
            enabled = enabled,
            role = Role.Button,
            interactionState = interactionState,
            indication = null
        )
    ) {
        Providers(LocalContentAlpha provides contentColor.alpha) {
            ProvideTextStyle(
                value = MaterialTheme.typography.button
            ) {
                Row(
                    Modifier
                        .defaultMinSizeConstraints(
                            minWidth = ButtonDefaults.MinWidth,
                            minHeight = ButtonDefaults.MinHeight
                        )
                        .indication(interactionState, rememberRipple())
                        .padding(contentPadding),
                    horizontalArrangement = Arrangement.Center,
                    verticalAlignment = Alignment.CenterVertically,
                    content = content
                )
            }
        }
    }
}

Usage:

Button(
    onClick = {},
    onLongClick = {},
    onDoubleClick = {}
) {
    Text(text = "I'm a button")
}
