Random runtime exception, not sure what's causing this

I am getting a runtime exception on the line in my code that sets the content view for the activity. This leads me to believe that my xml file must have an issue that I am simply not seeing. Any help at all would be greatly appreciated.

NOTE: The second TextView is set to blank because the activity associated with this view performs some calculations of which the result will be displayed in the second TextView.

<?xml version="1.0" encoding="utf-8"?>
<ReativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:background="@color/background" 
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" >

  <TextView 
    android:id="@+id/results_label_textview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="@string/results_label" 
    android:layout_centerHorizontal="true" />

    <TextView
    android:id="@+id/results_textview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text=" "
    android:layout_centerInParent="true" />

</ReativeLayout>

Any ideas? I imagine I have something coded wrong here.

UPDATE: Here's the Stack

I imagine you've solved this by now, but I had a similar problem with setContentView. After wasting hours checking syntax and spelling and surfing the web, all I had to do was clean the project and it worked perfectly.
