以编程方式更改 CardView 的背景颜色

CardView 有一个属性 card_view:cardBackgroundColor 定义背景颜色.此属性工作正常.

The CardView has an attribute card_view:cardBackgroundColor to define the background color. This attribute works fine.

同时也没有动态改变颜色的方法.

At the same time there isn't a method to change the color dynamically.

我刚刚尝试过以下解决方案:

I've just tried solutions like:

mCardView.setBackgroundColor(...);

或在 cardView 中使用 Layout

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);

这些解决方案不起作用，因为卡片有一个 cardCornerRadius.

These solutions don't work because the card has a cardCornerRadius.
