我是否应该能够在Eclipse Graphical Layout中看到android滚动条？

Question

I put in a scrollview in the XML of my program, and the graphical layout shows all of the fields bunched up in the screen, rather than having a scrollbar on this side and only some of the fields showing up (like I've seen in videos). I was wondering if this was normal, or something with my code or IDE is messed up. I use Eclipse with Windows 7. Thanks :)

My code is nearly identical to this one (the only things changed are the text:, and the IDs).

<?xml version="1.0" encoding="utf-8"?>

    android:layout_height="fill_parent">

            android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>

            android:layout_width="match_parent" android:id="@+id/etEmails">

        <TextView android:text="Person's name" android:layout_width="wrap_content"
            android:layout_height="wrap_content"></TextView>
        <EditText android:layout_height="wrap_content"

这是正常的行为（至少在我以前见过的所有Eclipse IDE上，以及我的看法）。
