sequentially should load data in viewpager fragments and the previous tabs view should be visible on switching back

I am using using viewpager to show 10 different fragments data at once.i used viewPager.setOffscreenPageLimit(7); to load all fragments data at once.But the issue is its taking a lot time to load the data .I want to load the data of particular tab which iam and the data should not be destroyed when i switch over to that tab again.

Saving tab information after swipe

I have 3 tabs in my application.
In my first tab I need to read JSON data from URL and using the user location. It takes about 2-3 seconds to load the page.
My problem starts when I implemented tabs, and now every time im swiping next and back, the info is re-fetched.
I tried the following solution:
I moved my method to the MainActivity, and created a variable named "isUpdated" and updated it to 1 if the info has been fetched successfully. since then, the tab data is gone after swiping and it shows blank empty tab.
I understand that the tab data is wiped after swiping to another tab, but I need to save the tab content.
How I can save the tab information and show it after the user swiped to the next tabs, without re-fetching the data over and over again?

if you are using ViewPager then set your off screen page limit to something different
for example
mViewPager.setOffscreenPageLimit(2);
should be enough for 3 tabs

The fragment data of the corresponding tab of viewpager need to be loaded only when the tab is clicked

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.

Android: data not loading in fragmentstateviewpager while setting current page

I am using fragmentstateviewpager where the fragments are created dynamically. Each page loads data by calling a web service. My viewpager will have 5 items, by default I am setting the current item as the 5th item using:
mPager.setCurrentItem(4);
The 5th item is getting displayed but data is not loaded in it. When I swipe two items back and comes again to the 5th item, now the data is loaded. Can anyone help me to solve this issue.

ViewPager refreshing itself

Am running in some weird problem. I have implemented ViewPagerTabStrip by following the tutorial Here
It's working fine and i have implemented Three Tabs.
On the first Page /tab , i am loading the data from server & displaying it in the ListView
The problem is, when i swipe to the Third Page & then i swipe back to Second page, the data of the first page is being loaded from the server again.( View of first tab is re-created.)
From the logs, it seems that this is the behavior of ViewPager & Adapter.
When we are on the first tab, it creates the view of second tab/ page as well in background & when we are on the Second tab, it was doing same for Third tab in background & upon reaching to third tab, it didn't created the view for it self(i.e third tab).
But when we swipe back to second tab, it re created the view of first tab as well.
How to solve this ? we can't afford to load the data from server again and again while swiping through the tabs.
I mean is there any way to stop the reload of data (or re-creation of view) while just swiping through tab pages? It should load the data when the whole fragment activity of View Pager is created and not at the time of swiping.
Any help on this please ?

Yeah, the ViewPager only keeps a certain number of fragments in memory before destroying them- this default number is usually two. Thus, what you have to do is tell the ViewPager to retain those fragments.
The simplest solution is to simply tell the ViewPager to keep three fragments in memory as follows:
viewPager.setOffscreenPageLimit(3);
Here are a few suggested answers on how to retain fragments (with more than just this method) and the reasoning behind the default behaviour as well as these solutions:
