title: Android: Do we really need to set id for view, which is created at RunTime(Dynamically) ?
body: <p>Android maintains all the resource ids in R.java. 
  What if we creates views at runtime without id ? Will they be included into R.java and those view's state will be maintained by android system like the view which was created with id?</p>
  
  <p><strong>Please let me know what are issues we would face at run time if we haven't set id for the views.</strong></p>
