Android: ScrollView not scrolling with keyboard out

I've got a layout with some views, from which one is an EditText. The layout easily fits on one page, BUT, when the soft keyboard is out, the layout doesn't scroll. Here's a recap of my layout:

<?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"
    android:background="@drawable/background" >

    <ScrollView
        android:id="@+id/ScrollView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true" >

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

            <CheckBox/>

            <TextView/>

            <LinearLayout>
                <EditText>
                    <requestFocus />
                </EditText>
            </LinearLayout>

            <TextView/>

            <LinearLayout>
                <Spinner/>
            </LinearLayout>

        </LinearLayout>

    </ScrollView>

    <Button
        android:layout_alignParentBottom="true" />

</RelativeLayout>

And in my manifest I have declared the attribute:

android:windowSoftInputMode="adjustResize|stateHidden"

Does anyone know why it doesn't work and how to make sure it does work?

Okay, apparently the ScrollView's android:layout_height mustn't be set to wrap_content. I set it to match_parent and set the android:layout_above to the button on the bottom of the page.

Don't ask me why, but this fixed the issue.
