make mPositionPerc public or add event to track position percentage

[fugogugo]

I see there's mPositionPerc that is used to rotate icon angle according to the position. But unfortunately it isn't accessible.

Actually this mPositionPerc is more useful than just to rotate the icon. I think it would be good if there's event to track this mPositionPerc . In my case I need this value to fade out my background alpha according to the slide position

I want to do it myself but I don't understand how to build the library

[fugogugo]

Oh wait I'm sorry.

apparently onSlideCompleteAnimationStarted treshold is exactly what I needed.

thank you :)

[fugogugo]

.... Apparently onSlideCompleteAnimationStarted only called when I release the slider .. so there's no actual event to track mPositionPerc in real time

so I will reopen this issue. sorryy

Hi @fugogugo, thanks for sending this feature request.

What you're asking is something like a:

interface OnSlideProgressListener {
    fun onSlideUpdated(view: SlideToActView, progress: Float)
}

as exposing just mPositionPerc will not fit your use case (you want to be notified when the progress change in order to updated your background).

I'm leaning towards not doing this change for mostly two reasons:

• Seems like this issue will solve only your specific issue and is not a general problem (so far you're the first requesting it).
• The listener will be invoked really frequently (during every gesture and animation multiple times). This could cause the widget to become laggy and is something that I would love to avoid.

I will leave the issue open to collect feedbacks from the community and hear what's the opinion of other users of the library.

I would love a listener like this. Helps in making animations in my activity more responsive and lively!

Can you please describe what you're trying to achieve?

I wish to dynamically fade out a fab that i have on my screen as the user slides the slider. It adds quite a good touch of responsiveness to it.

However, this is not an aesthetic i would want at the cost of performance

☝️ Exactly. My suggestion here would be to start a fade animation for your FAB once the onSlideCompleteAnimationStarted callback gets fired.

Is there anyway to implement a drag listener to this that Will give me How much is Being dragged ??

Not at the moment. That's what the issue is about as of today 👍
