title: Sticky Header/Footer with ScrollView in between
body: <p>I face that situation multiple times creating application and I don't really know how to handle it properly. These are the elements I want:</p>
  
  <ul>
  <li>Sticky view at the top (Toolbar or label...)</li>
  <li>ScrollView containing an undefined number of elements (Lets say EditText)</li>
  <li>Sticky button at the bottom that isn't part of the ScrollView.</li>
  </ul>
  
  <p>I lost when it comes to set the height of the ScrollView since it might varies depending of the phone size... Should I embed them all in a LinearLayout? (Header, ScrollView and footer)</p>
