body: <p>Is it possible to make a single row of listview not clickable?</p>
  
  <p>I am making a course search dialog which contains a listview. And when the user click the item in the listview, the course will be automatically added to the database. I want to make the courses which already exist in the database, not clickable, or simply not display the row. How can I do that?</p>
  
  <p>Thanks</p>
  
  <p>P.S. The adapter I used for the listview a customized BaseAdapter.</p>
