Hello All 👋 , Why CombinedClickable takes 1-2 seconds to perform action?. Is there any workaround solution for this?

Code in Thread 🙇

[Spikey Sanju]

Sample Code 👀

fun TaskItemCard(task: Task, onClick: () -> Unit, onDoubleTap: () -> Unit, onLongClick: () -> Unit) {
    // Emoji + (title + category)
    Row(
        modifier = Modifier
            .fillMaxWidth()
            .combinedClickable(onClick = {
                onClick()
            }, onDoubleClick = {
                onDoubleTap()
            }, onLongClick = {
                onLongClick()
            }),
        verticalAlignment = Alignment.CenterVertically,
        horizontalArrangement = Arrangement.Start
    ) {
        // Emoji Text View
        EmojiTextView(emoji = task.emoji)
        Spacer(modifier = Modifier.width(12.dp))

        // Title + Content
        Column(
            modifier = Modifier
                .align(Alignment.CenterVertically),
        ) {
            Text(
                text = task.title,
                style = typography.subtitle1,
                color = colors.onPrimary,
                maxLines = 1,
                overflow = TextOverflow.Ellipsis
            )
            Spacer(modifier = Modifier.height(12.dp))
            Text(
                text = task.category,
                style = typography.caption,
                color = colors.onPrimary.copy(.7f)
            )
        }
    }
}

It happens to me too at the very first click after app startup

Also I tried to use tap gestures to handle multiple touch events. But with those implementation also I face the same performance issue!

Romain has asked for any reproducable perf issues to be reported on the issuetracker for more visibility and so they can hopefully fix by 1.0

I would file there with the code and a video?

[Spikey Sanju]

Sure gimme a moment will send you the code & video

Take those samples and file a bug on issue tracker. 😁

I'm not on the compose team and have no idea why the issue might be happening.

ste: There have been a few discussions of performance at app startup, like this thread from Mar 11

With the combinedClickable modifier, when you have onDoubleClick set, onClick will fire only after 300ms of the click event, since we need to disambiguate between click and doubleclick and we need to wait 300ms for a potential doubleckick to happen (or not). This is the same way it works in the android views.

We hopefully can do better, but this is exactly the issue on why combinedClickable is experimental, so proceed with caution on this one.

This is most probably what is causing the delay in your case. If you see other delays and if you are able to provide a sample that will help me to reproduce the issue with the >300ms delay -- please file a bug and we will take a look.

[Spikey Sanju]

Got it. Sure will file a bug!
