Execute Code Each Time a Fragment in FramentStatePagerAdapter is viewed

Question

I am using a FragmentStatePagerAdapter to create a SlidingTabLayout with 3 tabs. I want to do something each time a Fragment is viewed on my screen. I've tried putting what I want to happen inside the onStart() of the respective fragment like so:

public void onStart() {
    //Do This
}

but it only works when the Fragment is moved 2 fragments away (i.e. 1st to 3rd, 3rd to 1st). Is there a way to do something each time a fragment is viewed on screen?

Answer 1

you can override setUserVisibleHint()

public class MyFragment extends Fragment {
  @Override
  public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if (isVisibleToUser) { 
       // here fragment is visible to user
    }
    else {  
    }

  }
}
