title: TextView pushes buttons off screen with HorizontalScrollView
body: <p>I am aiming for a layout similar to the native calculator app. I want text to trail off the left of the screen without moving the buttons on the right. Currently my text moves to the left until filling the screen at which point the buttons are pushed off the right edge.</p>

      android:gravity="right"
      android:orientation="horizontal" &gt;
  
      &lt;HorizontalScrollView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
