title: Android: multiple views in one activity
body: <p>I am new to android, and I am working on a Quiz app with a set of questions, each question has a question(text) and 4 images(imageButton), when user select the correct image, then they go to next question. So from question to question, should I:</p>
  
  <ol>
  <li>call setContentView() multiple times in one activity? (layout is same for all questions, only the question text and image changes)</li>
  <li>or add multiple layout in xml, and at runtime, set visibility of each layout? (but by doing so, I received warnings of too many views in one xml file)</li>
  <li>any other better suggestions?</li>
  </ol>
  
  <p>Thanks for your reply!</p>
