CardView background color always white
Kotlin for XML
app:cardBackgroundColor="@android:color/red"
code
cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));
If you want to change the card background color, use:
app:cardBackgroundColor="@somecolor"
like this:
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardBackgroundColor="@color/white">
</android.support.v7.widget.CardView>
Edit: As pointed by @imposible, you need to include
xmlns:app="http://schemas.android.com/apk/res-auto"
in your root XML tag in order to make this snippet function
You can do it either in XML or programmatically:
In XML:
card_view:cardBackgroundColor="@android:color/red"
Programmatically:
cardView.setBackgroundColor(ContextCompat.getColor(this, R.color.my_color));
