CardView elevation not showing in lollipop and higher versions

Question

I was using cardview, but the problem is elevation not showing in lollipop and higher versions. please suggest me.Here is my code.

<android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/verify_card"
        android:layout_weight="1"
        card_view:cardBackgroundColor="@android:color/white"
        card_view:cardElevation="2sp"
        card_view:cardUseCompatPadding="true"
        />

Thanks in advance.

card_view:cardUseCompatPadding="true" should have done the magic.. Just as an option try harware accelerated in application tag in manifest and check. — George Thomas, Jun 01 '16 at 14:10
Try to remove: card_view:cardElevation="2sp" or change it to "2dp". Cardview has an default elevation already... you don't need to set it... — guipivoto, Jun 01 '16 at 16:21

this worked for me.

xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"

total code is:

<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_margin="8dp"
    android:id="@+id/card_griditem"
    android:layout_height="match_parent"
    card_view:cardUseCompatPadding="true"
    card_view:cardElevation="4dp"
    card_view:cardCornerRadius="3dp">`

Actually `card_view:cardUseCompatPadding="true"` fixed my problem, thanks – Mehdi Karimi May 23 '18 at 14:19
I used android:elevation="4dp" instead of card_view:cardElevation="4dp" (or app:cardElevation="4dp) – Otziii Apr 01 '20 at 08:46

Make sure you have set android:hardwareAccelerated="false" as true in Manifest. By setting it to false your application will not able to use GPU and can't make some 2D designs.
