Anyone can help me with the correct way to change TextView's text in MotionLayout... this is what I doing.

I'm testing the MotionLayout on a Simple App...
I reach the part on the Motion tutorials about CustomAttributes

With them you can change the BackgroundColor of a View, also the textColor using customColorValue

In this case you can see it works very well changing this values in the start and end scene:

        <CustomAttribute

            motion:attributeName="backgroundColor"

            motion:customColorValue="#004A6D" />



        <CustomAttribute

            motion:attributeName="textColor"

            motion:customColorValue="#000000" />

enter image description here

Also I note that there is a customStringValue so I think I can change the TextView text to "BEFORE" -> "AFTER". But when I try to set this with CustomAttribute the app crash.

In the start scene:

<CustomAttribute

            motion:attributeName="Text"

            motion:customStringValue="BEFORE" />

And in the final scene:

        <CustomAttribute

            motion:attributeName="Text"

            motion:customStringValue="AFTER" />

Outside MotionScene the textView text is TEST:

When I set the CustomAttribute only for the end scene... the text change from initial value TEST to the end AFTER value... so it partially works but never return to the initial state.

This happend also when there is not initial text setted on the TextView. It works partially.

enter image description here

So... anyone can help me with the correct way to change TextView's text in MotionLayout.
