If ScrollView only supports one direct child, how am I supposed to make a whole layout scrollable?

Just wrap your current LinearLayout with ScrollView. So it should be smth like this:

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

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

        <ImageButton ... />
        <TextView ... />
        <TextView ... />
        <TextView ... />

    </LinearLayout>
</ScrollView>

The direct child of ScrollView should be another layout that supports multiple children, such as RelativeLayout or LinearLayout.

Worked perfectly.

Here is my layout as an example of scrolling a content item with two headers above it that stay stationary.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/mainMenu"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#FFFFFFFF"
xmlns:android="http://schemas.android.com/apk/res/android"
>
    <FrameLayout
    android:id="@+id/widget112"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
        <ImageView
        android:id="@+id/chemo_pro_header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/chemo_pro_header"
        >
        </ImageView>
        <ImageButton
        android:id="@+id/menu_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/menu_btn_off"
        android:background="@null"
        android:layout_gravity="right"
        android:padding="8px"
        >
        </ImageButton>
    </FrameLayout>
    <ImageView 
    android:layout_width="wrap_content" 
    android:id="@+id/news_head"
    android:src="@drawable/news_head" 
    android:layout_height="wrap_content">
    </ImageView>
    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
            <TextView android:layout_marginLeft="6dip" android:text="Monday, November 29th, 2010" android:id="@+id/newsDateStamp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:typeface="serif" android:textStyle="italic" android:textColor="#ff999999"></TextView>

if you want to scroll entire layout just make scrollview the parent and make Linear layout or anyother layout as it's first child and then add other layouts inside that .... example:

<Scrollview>
   <LinearLayout  android:id="@+id/child1">
     <Textview />
     <Textview />
     <Button />
     <LinearLayout>
       <Textview />
     </LinearLayout>
   </LinearLayout>
 </scrollview>

here Scrollview has only one child 'child1' rest all are inside it and hence entire layout is scrollable.
