android - Viewpager internal shell fragment slides horizontally. After the screen goes black, there is an overlap phenomenon when opened. There is only one fragment, which I reused. Hope God answers

Question

 mList.clear();
            mList.addAll(impress.object.get(0).data);
            fragmentList.clear();
            for (int i = 0; i < mList.size(); i++) {
                fragmentList.add(new PageFragment(mList.get(i)));
            }
            cartAdapter.notifyDataSetChanged();

After the black screen, swipe again and there will be overlap

Answer 1

@Override

public void onStop() {
    ViewGroup parent = (ViewGroup) rootView.getParent();
    if (parent != null) {
        parent.removeView(rootView);
    }
    super.onStop();
}

This should be fine.
