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...

I am having a webview inside my application with multiple links inside. On a one page I have a list of items, but when I am going to an another page and going back to this page, my page can't restore the scroll position. How to save scroll position in this case?
I have several pages some 8 pages on my dashboard containing viewpager and all have recycler view on it. The problem is when I swipe through viewpager, both swiping and recycler view setting adapter on the page happens at the same time on same ui thread due to which swiping lags and hence there is no smooth swiping and loading experience.
Things I tried using:
1. I tried putting delay to load the data but when swiping through, the previous fragment loads data due to which the ui lags again.
2. I also used setoffscreenpagelimit but I have some 8 pages and loading all at once or even some takes time to open the dashboard.
3. I tried using addOnPageChangeListener of the viewpager. But it lags the most.
Currently i am loading data when fragment is visible i.e in setUserVisibleHint method. I want to have a smooth swiping and loading experience. Help needed.
Thanks very much.
I have 3 fragments with WebView.
I'm using those three with ViewPager and Tablayout.
The Problem is whenever I'm swiping from 1st page to 3rd page and then going back to first page it's reloading and vice versa.
How do I preserve the state of Webview in Tablayout which has three or four pages.
By default, ViewPager destroys previous Fragments. You can change it using the following line -
mViewPager.setOffscreenPageLimit(CUSTOM_NUMBER);
I am having a viewpager and having 3 tabs in it. All the three tabs are having their fragments. What I noticed that each fragment data is getting loaded at the first time when I am setting adapter to viewpager.
What I need is to load the fragment data of the corresponding tab only when the particular tab is getting clicked.
I have noticed one more issue in it. Like when the activity started in which I am having viewPager, then the data of the first tab's fragment get loaded at the same time the data of the second tab's fragment also get loaded and that is shown when I click on that tab.
Same way when I click on Second Tab, third Tab's Fragment date get loaded.
So what I need is that the data of the fragment should be loaded only when I click on the particular tab.
Thank you so much in advance..
You should use the ViewPager.setOffscreenPageLimit(0) to only load the currently displayed content.
Its the View-pager behaviour that it loads one page left/right to current page even if you have specified setOfflinePageLimit(0).
To load each fragment on click on tab, you should use LocalBroadcastReciever.
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
