title: Call the same activity but with new parameters
body: <p>I'm trying to create calendar for android. There is a month switcher (previous/next month). How can I call the same activity (which displays the calendar) with other parameters...</p>
  
  <p>e.g. <strong>previous</strong> month will have <code>CalendarMonth(java.util.Calendar.MONTH - 1)</code> </p>
  
  <p>and <strong>next</strong> month will have <code>CalendarMonth(java.util.Calendar.MONTH + 1)</code> </p>
  
  <p>current month will have nothing in costructor</p>
  
  <p>Hope it's clear :)</p>
  
  <p>Thanks for help in advance</p>
