Answer 1

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));
}

Answer 2

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);

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 !!!
