fragment添加出口自定义动画在添加片段时无法正常工作android

Question

自定义退出动画适用于替换，但对于添加不适用

getNavFragment()
        .childFragmentManager
        .beginTransaction()
        .setCustomAnimations(
            enter,
            exit,
            popEnter,
            popExit
        )
        .add(R.id.fl_fragment_container, fragment, tag)
        .setReorderingAllowed(true)
        .apply {
            if (shouldAddToBackStack)
                addToBackStack(tag)
        }
        .commit()
