just add this line into your style.xml please add this on your Application main Style that you define in manifest

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:popupAnimationStyle">@style/Animation</item>
</style>

style.xml :

<style name="Animation">
<item name="android:windowEnterAnimation">@anim/your_specific_animation</item>
<item name="android:windowExitAnimation">@anim/your_specific_animation</item>
</style>
