How to scroll through more than one item? about discretescrollview

[srujanb]

Requested to merge. One can just download my repo for urgent use. Let me know of results.

Speaking strictly the gesture you describe is not scroll but "fling". If it's not too late I suggest you to try overriding DiscreteLayoutManager.onFling() and/or getHowMuchIsLeftToScroll().

[timshinlee]

@sevar83 Nice! You are right about fling. Thanks for your answer! I will try it out immediately.

[timshinlee]

@sevar83 Pity the DiscreteLayoutManager is not public. Is adding this library as module and making DiscreteLayoutManager public the only way to achieve this? I wonder why the author prefer not to make DiscreteLayoutManager public while offering DiscreteScrollView.setLayoutManger(DiscreteScrollLayoutManager layoutManager)?

@timshinlee were you able to solve this issue, this library is perfect except for being able to scroll through more than one item at a time.

[timshinlee]

@bnottingham Sorry. I tried but can't figure it out. @yarolegovich Would you consider adding fling through multiple items as a new feature?

[yarolegovich]

How do you propose to determine an amount of positions to scroll through?
Btw, I will be really happy to review and accept a pull request with this feature.

[timshinlee]

@yarolegovich Sorry I am not familiar enough with the scrolling mechanism to pull a solution request.
But just like RecyclerView itself or ListView, they can continue scrolling over certain distances after the finger flings.
I think using velocity to determine the amount of positions may be feasible.

[srujanb]

@timshinlee absolutely. Velocity can be decided to determine the amount of positions. @yarolegovich I tried to solve it but didn't succeed yet. Still trying though but I doubt to succeed. Even I'm dealing with the scrolling mechanism for the first time. You must have known all the tits-bits of the code. Can you either help or implement it yourself? For many this is the only lacking feature in the library. :)

[srujanb]

Oh wait! I just achieved it!

[timshinlee]

@srujan7 Really? I can't wait to see your solution.

[gr3ger]

Post your findings or make a merge request later please :3 I'm trying to get this to work as well.

[srujanb]

Give me few hours guys will make a pull req. ✌

[timshinlee]

@srujan7 Good job! Works like magic. Is it possible to furthermore allow sliding of multiple views on the drag gesture?
