Cardview background color does not change (dynamic component)

[Douglas_Maueski]

Why am I having this error?

Inside the cardview I have this button (green) and when I click on it I would like the corresponding cardview to change to green color.

I’ll try it here and if it gives any warning.

Thank you very much

It worked … thank you very much
