title: Android Layout - ScrollView blank space and in front of menus
body: <p>Its my first question here.
  I want the main page to have a scrollview with an image on top and some text on the botton of the imagem.
  Created the scrollview on other activity and included on the app.bar.main activity.
  Now I have 2 problems.
  1 there is a blank space on top of the imageview inside the scrollview.
  2 the scrollview gets in front of the toolbar, not letting me press the icons.</p>
