How do i change my cardview background with a custom background?-CodePudding

I made a box.xml file and it looks like this

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <solid android:color="#FF9800"></solid>
        <corners android:radius="10dp"></corners>
    </shape>
</item>

</selector>

For my cardview, I added android:background="@drawable/box" but the colour didn't change

CodePudding user response：

<androidx.cardview.widget.CardView

        app:cardCornerRadius="20dp"
        android:layout_margin="10dp"
        app:cardBackgroundColor="@color/white"
        app:cardMaxElevation="12dp"
