It looks like the challenge you posted this again is wanting you to copy and paste the TextView element and change 'TextView' to 'Button' - resulting in:

<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>
