Viewpager中的片段只有在旁边的片段打开时才会刷新

Question

So basically i have 4 fragments I'm currently working on second. I have some weird situation here. When app started it open fragment on position 1 then if I navigate to fragment 2 via tabs on top fragment 2 will update, then if I open fragment 3 from fragment 2 and return to fragment 2 from fragment 3 it will also update. But if I choose to open fragment 4 and then return to fragment 2 it won't refresh. This is method that I'm calling to refresh fragment

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if (isVisibleToUser) {
        loadEvents();
    }
    Log.d("TAG", "VISIBLE");
}

in LoadEvents there are few recyclerview setting their adapters. Nothing speciall

Answer 1

I think it is because when you call fragment 3 and when you return to the fragment 2 you use .replace , instead when you go to the fragment 4 you use .add and to return to the fragment 2 .show .

looks at the differences between:

• add
• replace
• show
