Android UI Design - How to display CardView below ImageView

I am trying to display products list using CardView for my android app. I have an ImageView that is complete so I want to display other products inside the card view which will be located just below the image view. Currently I am working on my XML file for my Activity but the only way I can display the Card View is by removing the android:layout_below="@+id/custom_indicator2" on my CardView element. When I do this, the card view displays on top of my Image View. How can I make do this while working on a Scroll View where in case I add more Card View content, I can just scroll down on my activity? The following is my code for my XML

<android.support.v4.widget.DrawerLayout
xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4"

android:layout_height="match_parent">

<ScrollView

    android:gravity="top" >
