I know this question has already been asked on different website (such as here and there for example, but I struggle to find a solution to my specific use case.
Here is the thing: I have 3 tabs (each tabs extends Fragment) which are hosted by an ActionBarActivity (called Home). Home holds a ViewPager which extends a FragmentStatePagerAdapter (this is where the differents tabs are created).
When I swipe to the last tabs (the 3rd one), I use setUserVisibleHint() to load some data from server using AsyncTask<>:
public class TabOperations extends Fragment {
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if(isVisible())
loadUserRequestByDate(); // Launch Asynctask<> method.
}
}
It works well when a swipe from first tab to the last one. But, When I swipe back to the tab before (so, the 2nd one), the method in setUserVisibleHint() (so, loadUserRequestByDate()) is triggered.
How can I avoid this behaviour?
Have you tried retaining the fragments with setOffscreenPageLimit(3) for your viewpager.
