failed to find style 'cardView Style' in current theme

Question

After updating support library version 27.1.0 Android Studio unable to render CardView. It shows error message as

failed to fi         


        

Answer 1

In my case the reason of the error with CardView was because of the wrong listheader attribute of a child Spinner. Alongside the failed to find style 'cardView Style' in current theme error message I got Spinner adapter view type count must be 1, so the roots of the CardView failing were surprisingly in Spinner rendering failure.
