title: android AlertDialog setView rules
body: <p>The <code>setView()</code> method of the <code>AlertDialog</code> class allows one to specify a custom view for the dialog box. Are there any restrictions as to what controls can be included in this custom view ?</p>
  
  <p>Also, if we set a custom view, can we still add buttons using <code>setPositiveButton()</code>, <code>setNegativeButton()</code>, etc ?</p>
