title: Custom adapter rebinds data to listview during scrolling
body: <p>I have a custom adapter that binds data (title, date, image) to a listview. Everything works fine, but when I scroll over my listview, it seems that the adapter re-binds its data to the listview. It does not populate or duplicate data but it writes over the same data position.
  Something like that, especially when I present images it is very annoying because the listview scrolling is not smooth.
  So, how I can stop the adapter to re-bind data on a listview?</p>
  
  <p>Thank you!  </p>
