Question

I want to do this so I can change the margin within an animation-list.

This would move the button closer or further from the edge of the screen.

Answer 1

This isn’t possible but it’s easy to create an animation like so

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator">
    <translate android:fromYDelta="0" android:toYDelta="100%" />
</set>

and then simply add the animation to the object and start it.
