Hello I am am working on demo application in which i am using the card view of support library. By default it is adding shadow around it. I want to remove this shadow & should looks like simple.

I tried this that is not working for me.

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

i used `http://schemas.android.com/apk/res-auto` for namespace definition and it worked. `http://schemas.android.com/tools` didnt work for me. Anybody knows the reason? – Cerlin Mar 27 '17 at 10:43
@CerlinBoss what's your namespace-prefix? `card_view` or `app`? – Loyea Mar 27 '17 at 10:59
@Loyea : card_view – Cerlin Mar 27 '17 at 14:32

do not use card_view:cardElevation. replace it with app:cardElevation – Ahamadullah Saikat Jun 24 '18 at 14:11
@CerlinBoss, the tools namespace is for design purposes. It allows you to model actual behaviour of the view during design time. Example, you can use the `tools:text` property to set visible text during design instead of the `android:text`. – Clement Osei Tano Jan 18 '19 at 15:28
am new to android what is cardElevation means ? – shareef Mar 17 '19 at 04:47

@AhamadullahSaikat answer worked for me. I'm using Androidx libraries – ylinkz Jul 26 '19 at 02:15

Try to put the elevation in Xml.

app:cardElevation="0dp"

OR

cardView.setCardElevation(0);

And check you are using the latest CardView library.

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 !!!

There is no such method `setCardElevation` – N Sharma Nov 06 '14 at 09:51
This method is available in latest library but when I use new library then I am getting this http://stackoverflow.com/questions/26675682/exception-android-view-inflateexception-binary-xml-file-line-2-error-inflat – N Sharma Nov 06 '14 at 10:03

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"

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 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>

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));
}

@Williams this is code in the CardView source - if you want to create your own CardView — d4c0d312, Sep 01 '16 at 05:16
