屏幕打开后，AppCompatDialogFragment启动windowEnterAnimation

Question

我有一个带有一些动画的AppCompatDialogFragment

override fun onActivityCreated(savedInstanceState: Bundle?) {
        super.onActivityCreated(savedInstanceState)

        dialog.window.attributes.windowAnimations = R.style.FragmentAnimation
    }

-

 <style name="FragmentAnimation">
        <item name="android:windowEnterAnimation">@anim/slide_up</item>
        <item name="android:windowExitAnimation">@anim/slide_down</item>
    </style>

-

dialogFragment.show(supportFragmentManager, "TAG")

一切正常，除非显示对话框，然后关闭然后打开屏幕，然后重新输入动画。怎么解决？
