You can create any layout animations

<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
    android:animation="@anim/item_animation_from_bottom"
    android:animationOrder="normal"
    android:delay="15%" />

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="500">

    <translate
        android:fromYDelta="50%p"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:toYDelta="0" />

    <alpha
        android:fromAlpha="0"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:toAlpha="1" />

</set>

From the code

AnimatedRecyclerView recyclerView = new AnimatedRecyclerView.Builder(this)
                .orientation(LinearLayoutManager.VERTICAL)
                .layoutManagerType(AnimatedRecyclerView.LayoutManagerType.LINEAR)
                .animation(R.anim.layout_animation_from_bottom)
                .animationDuration(600)
                .reverse(false)
                .build();
