I have a ViewPager with two pages. in page 1 is a chart with a movable pointer.
I want to when user changing the pointer location with touch, ViewPager pages dont change and stay on page 1.
best and simple way you first migrate viewpager to viewpager 2 and then just one line code you can disable swiping touch page
viewPager2.setUserInputEnabled(false);
and enable
viewPager2.setUserInputEnabled(enable);
Please check : Migrate from ViewPager to ViewPager2

So I have a single activity that controls a viewPager and this viewPager controls five fragments. In one of the fragments, there is an ImageView.
I want this imageView transit to the next page when I do a swipe left. More specifically, the position of this imageView will transit as I am swiping and once the swiping is done and the next fragment layout is completely shown on the screen, this ImageView should be a fixed location in this layout.
Does anybody know how I can make this work?
Thanks!
I think I know what you mean. It might be easier to make it a separate View on top of the pager, perhaps disabled so drags will go through it. and then you need to get a live reading of the position of the page. onPageScrolled on ViewPager.OnPageChangeListener is pretty cool and gives you what you need to place elements or do other transitionary effects based on the actual position of the Views in your ViewPager.
I have a ViewPager with a FragmentPageAdapter set for it.
And the ViewPager is show some simple fragment.
I am able to use ViewPager for swipe between fragments.
However, I don't like the scrolling effect of ViewPager that showing partial content of next fragment while swiping/dragging current fragment.
Instead, I would like to switch to next fragment at instant with swipe(but without scrolling effect) and show fragment immediately.
How can I do such thing(must use ViewPagger)?
You have to implement your own "SwipeDetector" and use mViewPager.setCurrentItem(index, false) method (second parameter indicates whether to enable animation or not).
Is it possible to have a Viewpager that knows what the current, next and previous page is and when I swipe either way the state changes so there always will be max 3 pages?
Hope you get the point
ViewPager has the OnPageListener. the onPageSelected gives you the position of the current page selected
I have got three pages in my viewpager and by default i have to set the middle one. But for the first time I want to swipe the viewpager a little left and then right to indicate to a user that there are also two more pages, left and right to it. Please guide regarding the automatic partial swipe of viewpager.
Thanks.
please refere this sample code.In this example you will get how to do automatic swipe of viewpager.

before using this library i also have some problem when i use pager.
I have a layout with a ViewPager and also right left arrows inside the ViewPager for manually moving to the next view without swiping.
While the user is swiping, I'd like to hide those arrows (or maybe only show the right one when the user is swiping to the right...)
How can I find out if the user is scrolling a ViewPager?
Found the solution:
Method onPageScrollStateChanged from SimpleOnPageChangeListener
http://developer.android.com/reference/android/support/v4/view/ViewPager.SimpleOnPageChangeListener.html#onPageScrollStateChanged(int)
the state argument of onPageScrollStateChanged is 1 when you start draggin, 2 when you let go and 0 when the ViewPager has stopped scrolling
