title: Always display a button
body: <p>I created a scrollable table layout in xamarin . I want a button to be always displayed in the bottom of screen (the help button),no matter if I scroll the table,the button is shown. </p>
  
  <p>I put the button on a relative layout. How can I do the relative layout (which is on the linear layout) , not to be scrollable and also always to be on screen?</p>
  
  <p>This is my code:</p>
