title: Can i extend the size of a listview dynamically in java code
body: <p>I am using a listview in a layout with a size- not in full size of layout.
  Below the layout there are components like button.
  I need the layout to get extended when more number of listitems adds dynamically.</p>
  
  <p>I have kept the listview and buttons in scrollview.</p>
  
  <p>Is there any attribute or option to make listview of variable length</p>
