View inside ScrollView doesn't take all place

I have a RelativeLayout inside a ScrollView. My RelativeLayout has android:layout_height="match_parent" but the view doesn't take the entire size, it's like a wrap_content.

Is there a way to have the real fill_parent/match_parent behavior ?

My layout :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    <ImageView
    android:id="@+id/top"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:scaleType="fitXY"
    android:src="@drawable/top" />

    <ImageView
    android:id="@+id/header"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/top"
    android:scaleType="fitXY"
    android:src="@drawable/headerbig" />

    <ImageView
    android:id="@+id/logo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/header"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="3dp"
    android:src="@drawable/logo" />

    <ScrollView
    android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/bottom"
    android:layout_below="@+id/logo"
    android:background="@drawable/background" >

        <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

             <ImageView
            android:id="@+id/dashboard01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_above="@+id/dashboard02"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="30dp"
            android:src="@drawable/dashboard01"
            android:visibility="visible" />

            <ImageView
            android:id="@+id/dashboard02"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_alignParentRight="true"
            android:layout_marginRight="10dp"
            android:src="@drawable/dashboard02" />

             <ImageView
            android:id="@+id/dashboard03"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/dashboard02"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="40dp"
            android:src="@drawable/dashboard03"
            android:visibility="visible" />
         </RelativeLayout>
    </ScrollView>

    <ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/logo"
    android:layout_centerHorizontal="true"
    android:scaleType="fitXY"
    android:src="@drawable/bar" />

    <ImageView
    android:id="@+id/bottom"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:scaleType="fitXY"
    android:src="@drawable/bottom" />

</RelativeLayout>

Try adding android:fillViewport="true"to your ScrollView

remember that android:layout_height=”fill_parent” means “set the height to the height of the parent.” This is obviously not what you want when using a ScrollView. After all, the ScrollView would become useless if its content was always as tall as itself. To work around this, you need to use the ScrollView attribute called android:fillViewport. When set to true, this attribute causes the scroll view’s child to expand to the height of the ScrollView if needed. When the child is taller than the ScrollView, the attribute has no effect.
