title: retaining data on screen orientation change
body: <p>I have an activity that has a huge form with lots of EditTexts. If the user rotates the screen from portrait to landscape or vice-versa, all the data in the EditTexts is lost. Is there some way to retain the data so that it is not lost while changing the orientation?</p>
  
  <p>I have created 2 layouts, one each for portrait and landscape. I also have the same IDs for all the Views in both the layouts.</p>
  
  <p>Thanks in advance.</p>
