The CardView has an attribute card_view:cardBackgroundColor
to define the background color.
This attribute works fine.
At the same time there isn't a method to change the color dynamically.
I've just tried solutions like:
mCardView.setBackgroundColor(...);
or using a Layout inside the cardView
<android.support.v7.widget.CardView>
<LinearLayout
android:id="@+id/inside_layout">
</android.support.v7.widget.CardView>
View insideLayout = mCardView.findViewById(R.id.inside_layout);
cardLayout.setBackgroundColor(XXXX);
These solutions don't work because the card has a cardCornerRadius.
What you are looking for is:
CardView card = ...
card.setCardBackgroundColor(color);
In XML
card_view:cardBackgroundColor="@android:color/white"
Update: in XML
app:cardBackgroundColor="@android:color/white"
