title: java.lang.IllegalStateException: ScrollView can host only one direct child
body: <p>I'm simply trying to add the ability to scroll through this layout by adding a scrollview however every time I attempt to load the layout I'm getting an error stating "java.lang.IllegalStateException: ScrollView can host only one direct child" and I'm unsure why. </p>
  
  <p>Any suggestions are much appreciated.</p>
