ColorDrawable cannot be cast to android.support.v7.widget.RoundRectDrawableWithShadow

Question

The issue I am having is basically what is found in this answer but I will still explain below. I am testing on a device with android 5.0.1 and another with 4.2.2. On my device with 5.0.1 I get no errors and everything behaves as expected. On my 4.2.2 device I get the following error:

java.lang.ClassCastException: android.graphics.drawable.ColorDrawable cannot be cast to android.support.v7.widget.RoundRectDrawableWithShadow

with the error occurring at this line: card1.setBackgroundColor(getResources().getColor(R.color.White));

Now as suggested by the linked answer I have tried using setCardBackgroundColor however this causes the error to be produced on both my devices. Any suggestions?

The CardView I am attempting to use is a android.support.v7.widget.CardView

This is the layout producing the error:

After reading through the issue described here I noticed that it has since been closed. As far as I am aware I am using the most updated version of the platform tools and sdk tools and I still have this issue.

After some further testing, I have discovered that the emulator I am using does not have GooglePlayServices. I do not currently have access to a physical device with less than Android 6.0 to test on. Is it a possibility that not having GooglePlayServices could cause this issue?

Answer 1

This is working for me for cardview inside recycleview

 ((CardView)viewholder.itemView).setCardBackgroundColor(Color.WHITE);
