[移动开发]ViewPager2 切换时高度问题

vpRegister.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {
            @Override
            public void onPageSelected(int position) {
                super.onPageSelected(position);
                View view = fragmentList.get(position).getView();
                updatePagerHeightForChild(view, vpRegister);
            }
