Why RecyclerView adapter for ViewPager2?

Why do we use RecyclerView adapter for the ViewPager2? Why doesn't it use its own class for the adapter? I see ViewPager2's class and it does not extend or do anything with reycler view. Then why RecyclerView's adapter?

Because ViewPager2 is just a specialised container of a RecycyerView.

It's a bit hidden

But from the code

     private class RecyclerViewImpl extends RecyclerView {
        RecyclerViewImpl(@NonNull Context context) {
            super(context);
        }

and then in the initialize method of viewpager2

private void initialize(Context context, AttributeSet attrs) {
        mAccessibilityProvider = sFeatureEnhancedA11yEnabled
                ? new PageAwareAccessibilityProvider()
                : new BasicAccessibilityProvider();
        mRecyclerView = new RecyclerViewImpl(context);
