CardView within a ScrollView

Navigation
0

I can not get the scrollview to work in my cardview .... As the scrollview works with a single child, I changed the main layout to ScrollView and created a linearLayout to encompass the rest within it. but it does not work at all, I did exactly that code link 

<LinearLayoutandroid:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#1f7bbc"
    android:orientation="vertical"
    android:weightSum="10"

    >


    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_weight="2">


        <ImageView
            android:id="@+id/imageView3"
            android:layout_width="match_parent"
            android:layout_height="match_parent"


            android:layout_alignParentTop="true"
            android:padding="0dp"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/anuncio" />


    </RelativeLayout>


    <GridLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="8"
        android:alignmentMode="alignMargins"
        android:columnCount="2"
        android:columnOrderPreserved="false"
        android:padding="14dp"
        android:rowCount="3">
