Fragment onResume() isn't called when using FragmentPagerAdapter

Question

I need my fragments to always call a certain function when they are the active fragment, so I put it in onResume(), but it isn\'t being called.

Fragment A

Answer 1

I had the same problem while ago.

Create a new interface and implement it by both of your Fragments:

public interface OnPageSelectedListener {
    void onPageSelected();
}

In parent activity implement android.support.v4.view.ViewPager.OnPageChangeListener and call Fragment method like this:

@Override
public void onPageSelected(int i) {
    OnPageSelectedListener fragment = (OnPageSelectedListener ((PlaceListPagerAdapter)pager.getAdapter()).getFragment(i);
    fragment.onPageSelected();
}

PS: Name of the new interface and its method is a bit confusing, so be careful or change it.
