Solution 1 - Android
use this attribute in XML
card_view:cardElevation="0dp"
and remember add xmlns:card_view="http://schemas.android.com/tools"
in your root layout.
OR you can call cardView.setCardElevation(0)
to disable shadow programmatically.
cardView.setElevation()
method and CardView attribute android:elevation
will throw java.lang.NoSuchMethodError in platform before Android 5.0
Solution 2 - Android
Try to put the elevation in Xml.
app:cardElevation="0dp"
OR
cardView.setCardElevation(0);
And check you are using the latest CardView library.
Solution 3 - Android
use app:cardElevation="0dp", don't use app:elevation="0dp"
Solution 4 - Android
Just put this line inside your CardView:
app:cardElevation="0dp"
Hope it will help you.
Solution 5 - Android
You can have it in XML like:
<android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
app:cardElevation="0dp"
app:cardCornerRadius="0.5dp"
app:cardPreventCornerOverlap="false"
app:cardUseCompatPadding="true"
>
</android.support.v7.widget.CardView>
hope it helps you !!!

try like this may help you,
CardView cardView = (CardView) v.findViewById(R.id.cardView);
cardView.setCardElevation(0);
Solution 7 - Android
You should first add this to the your parent layout
xmlns:card_view="http://schemas.android.com/tools"
then set the elevation like this
card_view:cardElevation="0dp"
Solution 8 - Android
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardElevation="0dp"
app:cardCornerRadius="2dp">
....`
</android.support.v7.widget.CardView>
Solution 9 - Android
If anyone is looking for kotlin answer then this worked for me
card_layout.cardElevation = 0F
Solution 10 - Android
In my case, only setting of background alpha with suggested elevation and backgroundColor hide shadow border:
this.setCardElevation(0);
this.setCardBackgroundColor(getContext().getResources().getColor(android.R.color.transparent));
this.getBackground().setAlpha(0);
Solution 11 - Android
You have to use the following attributes
<android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardElevation="0dp"
app:cardCornerRadius="0.5dp"
app:cardPreventCornerOverlap="false"
>
</android.support.v7.widget.CardView>
Solution 12 - Android
CardView sets its own elevation during initialization, which will override whatever you set from XML. You should file this as a bug at chek this
@Override
public void initialize(CardViewDelegate cardView, Context context, int backgroundColor,
float radius) {
cardView.setBackgroundDrawable(new RoundRectDrawable(backgroundColor, radius));
View view = (View) cardView;
view.setClipToOutline(true);
view.setElevation(context.getResources().getDimension(R.dimen.cardview_elevation));
}
Solution 13 - Android
Attenion: Attribute outlineSpotShadowColor is only used in API level 28 and higher
app:cardElevation="0dp"
android:outlineSpotShadowColor="@android:color/transparent"
