android:textSize change in MotionLayout

Question

I am going to animate text size change using MotionLayout.

I do the following for start state

<CustomAttribute
    motion:attributeName="textSize"
    motion:customDimension="16sp" />

And the following for end state

<CustomAttribute
    motion:attributeName="textSize"
    motion:customDimension="14sp" />

As a result, it looks like size is actually changing, but it's much larger than 14sp-16sp

So, how to change text size properly?

Answer 1

Try this

<CustomAttribute
    motion:attributeName="textSize"
    motion:customFloatValue="14" />
