I have a fragment that is to replace another fragment. I want to specify the animation. But the animation is ignored.

transaction.replace(R.id.my_fragment, newFrag);
transaction.addToBackStack(null);
transaction.setCustomAnimations(R.anim.slide_in_up, R.anim.slide_out_up);

slide_in_up

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromYDelta="0%p"
    android:toYDelta="100%p" />

slide_out_up

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromYDelta="100%p"
    android:toYDelta="0%p" />

All I am really trying to achieve is for the new fragment to slide in from the bottom. My animations are ignored. What is the code missing?

Currently with android.transition this is as simple as fragment.enterTransition = Slide() or fragment.enterTransition = Fade()

Note: Min version L.

This answer is written in Kotlin. For sake of the example, I'm just hiding or showing it based on it's current isHidden attribute. I'm using androidx.transition.Slide

Link: https://developer.android.com/reference/androidx/transition/Slide

val frag = supportFragmentManager.findFragmentById(R.id.frag_id_from_xml_layout)
frag?.let {
    val ft = supportFragmentManager.beginTransaction()
    frag.enterTransition = Slide()
    frag.exitTransition = Slide()
    if (frag.isHidden) ft.show(frag) else ft.hide(frag)
    ft.commit()
}
