Move your button code inside of your relative layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent" >

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

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

</RelativeLayout>
