title: How to call onClick(View v) method explicitly in an Android? Is it possible?
body: <p>I want to call an <code>onClick(View v)</code> of other class from my activity's method <code>onCreate()</code>. Is it possible? </p>
  
  <p>Because I have a Popupwindow in an onClick method of other class, so when an orientation changes, I want my landscape mode's popupwindow to be intact and appear at runtime. How can it be done?</p>
  
  <p>Thanks in advance!</p>
