android - Change the background color of CardView programmatically

Question

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.

Answer 1

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"
