Android Question AHViewPager touch event conflict

Hi all,

as I wrote here on explanation of this library I released .....
https://www.b4x.com/android/forum/t...er-that-can-do-slider-or-progress-bar.141213/
..... I'm happy with it, the only issue I've found is using it on top of AHViewPager, for vertical sliders no problems, but for horizontal sliders the touch conflicts with ViewPager and I don't know how to solve it.

It only works if after touching the slider I move the finger outside it (slide vertically).

Because I had the same problem with others similar my controls libraries, now I think it's time to investigate it.

This happen not only on my control libraries, I had the same issue on a WebView placed on the ViewPager where I need to use a finger to rotate a 3D scene created with threejs library, to grant touch control I need to swipe the view vertically, then it works, swiping horizzontally it fails and ViewPager use the touch event to swipe the page.

On opposed in my current project I use some my custom buttons, when I want to swipe to change the page, these buttons sometimes was clicked randomly and this is not good.

Attached a small video (and zip project) that reproduce this issue on class I already released, the project depends on CustomMinimalSlider library you can find in the link posted, here I posted the .jar, .xml files, but even 2 demo projects, in the first one there is a full class inline that can be recompiled as library.

Please, can someone help me to know how to solve this issue ?

Many thanks

Here as promised the full zip project to reproduce the issue.

The CustomMinimalSlider class is inline, just need a reference of AnimationPlus library because depends on it for animations.

The issue is only on horizontal slider, now it do not conflicts, but paging is not reenabled when the slider is moved to zero or max value, the flag is true but really it is blocked and do not permits to change page.

Probably this is something that happen when I release the slider out of its bounds because if I click labels to set zero value or max value it is working.

Please, can you help me to fix it ?
