I have removed the last 2 rows to reduce code

Answer 1

you need to add this in your cardview xml file :

app:cardUseCompatPadding="true"
card_view:cardElevation="4dp"

Answer 2

I suggest you to use NestedScrollView instead of ScrollView.

Something like below code:

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:scrollbars="none">

    <GridView 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"/>
