Access Context in PagerAdapter

Question

As you know, for inflating a view, we need context to get LayoutInflater .I have seen many tutorials that pass context as an argument to PagerAdapter to solve this problem. I recently have found that we can access context from instantiateItem like below:

@NonNull
@Override
public Object instantiateItem(@NonNull ViewGroup container, int position) {
    Context context = container.getContext();
    ...
}

but I wonder whether it is best practice or not?

Answer 1

Yes, totally fine. A ViewGroup is a View and getContext() will return you a Context to which the view is attached to, ie it's the outbound Activity . This is the context that you want to use for accessing layouts and resources while rendering adapter items.
