Load data when setUserVisibleHint is deprecated in AndroidX

Question

I use ViewPager to store fragments and I just want to download data when I come to this fragment, so I do like this

public abstract class ModelFragment extends Fragment {
    
        @Override
        public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,Bundle savedInstanceState) {
            if(getUserVisibleHint()){ // fragment is visible
                loadData();
            }
            return super.onCreateView(inflater, container, savedInstanceState);
        }
    
        @Override
        public void setUserVisibleHint(boolean isVisibleToUser) {
            super.setUserVisibleHint(isVisibleToUser);
            if (isVisibleToUser && isResumed()) { 
                loadData();
            }
        }
    
        public void loadData(){
            // data for fragment when it visible here
        }
    }

But now in androidx, setUserVisibleHint is deprecated so what is the best solution here?

You can use onResume and onPause methods instead of setUserVisibleHint. For this you have to change default behaviour in FragmentPagerAdapter constructor.

FragmentPagerAdapter(fragmentManager, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT)

Checkout this https://developer.android.com/reference/androidx/fragment/app/FragmentPagerAdapter#BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT

So when you check getUserVisibleHint, just check the variable isResumed? – Thang Jul 16 '20 at 08:05
