CardView: Setting background color removes the rounded edges

I have a cardview with rounded corners:

 <androidx.cardview.widget.CardView
        android:id="@+id/chronology_card"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="2dp"
        app:cardCornerRadius="12dp">   <------- corner radius set in the layout.

view is showing with rounded corners. -> ok.

When setting the backgroundcolor by code ...

holder.cardView.setBackgroundColor(getBackgroundColor());

... then the rounded corners are gone. It lookes like a rectangle with the correct new color.

How to set the backgroundcolor at runtime and keeping the corners?

The CardView manages its own background drawable with rounded corners.
Using setBackgroundColor you are overriding this background.

You should use the method setCardBackgroundColor instead of setBackgroundColor.

You can try to add this to your activity code:

CardView cardView = findViewById(R.id.chronology_card);
cardView.setCardBackgroundColor(Color.parseColor("#put here the HEX code for the color"));

I tried it before and worked fine without any problems in corners radius.
