Answer 1

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">`

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.
