The easier way is to use :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <LinearLayout
        android:id="@+id/headerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true" >
    </LinearLayout>

    <ScrollView
        android:id="@+id/scrollablContent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/footerView"
        android:layout_below="@+id/headerView" >

        <LinearLayout
            android:id="@+id/content"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
        </LinearLayout>
    </ScrollView>

    <LinearLayout
        android:id="@+id/footerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" >
    </LinearLayout>

</RelativeLayout>

You have to replace the external container from LinearLayout to RelativeLayout, then set the alignParentTop=true for the header ImageView, alignParentBottom=true for the footer ImageView, and set layout_above="@+id/imageViewFooter", layout_below="@+id/imageViewHeader" for the ScrollView. Like this:

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/imageViewHeader"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="false"
        android:layout_alignParentTop="false"
        android:scaleType="fitXY"
        android:src="@drawable/square" />

    <ImageView
        android:id="@+id/imageViewFooter"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:layout_alignParentBottom="true"

        android:scaleType="fitXY"
        android:src="@drawable/square" />

    <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/imageViewFooter"

        android:layout_below="@+id/imageViewHeader" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical" >

            <Button
                android:id="@+id/button1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Button" />

            <Button
                android:id="@+id/button2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Button" />

            <Button
                android:id="@+id/button3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Button" />

            <Button
                android:id="@+id/button4"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Button" />
        </LinearLayout>
    </ScrollView>

</RelativeLayout>
