I am trying to extend a sample I found at http://developer.android.com/resources/articles/layout-tricks-efficiency.html. I am a brand new MonoDroid developer, just installed it yesterday, and trying to jump right into UI design and so far it is not clicking for me completely.

I have this main.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:padding="6dip">
  <ImageView
      android:id="@+id/icon"

      android:layout_width="wrap_content"
      android:layout_height="fill_parent"

      android:layout_alignParentTop="true"
      android:layout_alignParentBottom="true"
      android:layout_marginRight="6dip"

      android:src="@drawable/icon" />

  <TextView
      android:id="@+id/secondLine"

      android:layout_width="200dip"
      android:layout_height="26dip"

      android:layout_toRightOf="@id/icon"
      android:layout_alignParentBottom="true"
      android:layout_alignParentRight="true"

      android:singleLine="true"
      android:ellipsize="marquee"
      android:text="Second line which is a long line of text and needs to scroll" />

  <TextView
      android:id="@+id/firstLine"

      android:layout_width="200dip"
      android:layout_height="wrap_content"

      android:layout_toRightOf="@id/icon"
      android:layout_alignParentRight="true"
      android:layout_alignParentTop="true"
      android:layout_above="@id/secondLine"
      android:layout_alignWithParentIfMissing="true"

      android:singleLine="true"
      android:ellipsize="marquee"
      android:gravity="center_vertical"
      android:text="First line" />

  <Button
      android:id="@+id/logonButton"

      android:layout_width="50dip"
      android:layout_height="wrap_content"

      android:layout_toRightOf="@id/secondLine"
      android:layout_alignParentRight="true"
      android:layout_alignParentTop="true"

      android:gravity="center_vertical"
      android:text="Login" />
      />
</RelativeLayout>

What I am trying to do is have an icon on the left, 2 lines of text stacked in the middle and a button on the right. When I run this in my emulator I am seeing:

1. The second line is not scrolling.
2. The button does not show up.

Is there by any chance a simple WYSIWYG editor for layout? Or is there an app to give me a quick view of my layout XML? Something like FireBug in FireFox would be fine.

Barring the slim chance there are UI helpers for Droid, what am I doing wrong? :)
