Solution 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"

Solution 2

Use the property card_view:cardBackgroundColor:

<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/card_view"
    android:layout_width="fill_parent"
    android:layout_height="150dp"
    android:layout_gravity="center"
    card_view:cardCornerRadius="4dp"
    android:layout_margin="10dp"
    card_view:cardBackgroundColor="#fff"
    >

Solution 3

You can use this in XML

card_view:cardBackgroundColor="@android:color/white"

or this in Java

cardView.setCardBackgroundColor(Color.WHITE);

Solution 4

I used this code to set programmatically:

card.setCardBackgroundColor(color);

Or in XML you can use this code:

card_view:cardBackgroundColor="@android:color/white"

Solution 5

I was having a similar issue with formatting CardViews in a recylerView.

I got this simple solution working, not sure if it's the best solution, but it worked for me.

mv_cardView.getBackground().setTint(Color.BLUE)

It gets the background Drawable of the cardView and tints it.

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.

+1 for hacking and I agree. I can't find a better solution. Anyway I hope in something different in official API.

Is this class(RoundRectDrawableWithShadow or RoundRectDrawable) accessible? I don't think so

It seems a new method in support lib. I didn't see it the last month, may be it is an update

You are adding a LL in your cardview in this way and of course you can do it, but it doesn't answer the original question.

The request was about changing the card background color dynamically, and i think this method does it pretty simply by changing the inner layout background color. Or am i missing something.

Thanks for pointing out the XML styling. Always struggling with that. Isn't there a way to define the style in themes.xml? Then you wouldn't have to set the style for each CardView.

This answer is more usefull because contains the static (XML) and the programmatic way (JAVA) Kudos.

Might want to add that the way to configure this in XML is card_view:cardBackgroundColor="@android:color/white"

Using card_view namespace doesn't work for me, I have to use app instead.

That is pretty awesome - I was struggling with trying to figure out how to propagate selectors down through the layout - and this was NOT working pre API21. The ripple was working fine post API21- but your theme approach was the first time I managed to get the CardView to give the right look on clicking across the contents.

@rsicarelli All depends on what you name it: xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:card_view="http://schemas.android.com/apk/res-auto"

The OP tell us about that property in the first line of his question, he said he wants to achieve it "dinamically".
