How to disable the shadow around card view in android

Question

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.

CardView cardView = (CardView) v.findViewById(R.id.cardView); cardView.setElevation(0); 

After doing these I am getting crash

layout.xml

<?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:card_view="http://schemas.android.com/apk/res-auto"     xmlns:app="http://schemas.android.com/apk/res/com.xyz"     android:id="@+id/cardView"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_marginBottom="5dp"     android:layout_marginLeft="5dp"     android:layout_marginRight="5dp"     android:orientation="horizontal" > 

Thanks in advance.

Answer 1

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

Answer 2

Try to put the elevation in Xml.

app:cardElevation="0dp" 

OR

cardView.setCardElevation(0); 

And check you are using the latest CardView library.
