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 ViewPager inside DialogFragment and I have three Fragment in the ViewPager each having a spinner which updates from the API calls.Whenever the fragment is initiated its get spinner values from the server
Now the problem is when ever user swipe the pager let say i swipe from page 1 to page 2 than the spinner value gets updated from page 3
I know that ViewPager has mViewPager.setOffscreenPageLimit(MAX_LIMIT); but minimum value is 1
Is there any way or work around for this problem ?
I have refer this Example
I have 4 tabs, first with grid view of photos and three without anything content, why when i swipe from first to three or four tab and return to first all my grid reload data from server, how to disable it?
Hi try to set your method setOffscreenPageLimit() of PageViewer
viewPage.setOffscreenPageLimit(3);
How setOffScreenPageLimit works:
When you use the default implementation of setOffscreenPageLimit() it is only loading the one fragment which is to the right of it. For eg. when you are on index 1, it has index 2 loaded in memory but not index 0, so swiping left will have to generate a new fragment from scratch.
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
I have a Gridview in all page inside ViewPager. When I try to load the images in gridview in all page, it doesn't updated the current page because problably ViewPager caches the recent views. So when I navigate to further pages, I can see the changes. How can I make the current page show the changes. Thanks...
Based on FragmentPagerAdapter, I have inflated my view pager and I can see my items in each page. How to know, which page is clicked by user to direct him/her see detail of information?
Thanks
As far as I know, there is no way to get the current displayed Fragment by the FragmentPagerAdapter, so what I can suggest is keep an position member variable for each Fragment that is added in the pager so you can use that to know which fragment is clicked.
