title: get edittext data from other fragment's of ViewPager
body: <p>I am creating a sliding window effect by using <code>ViewPager</code> and <code>FragmentPagerAdapter</code>. I have three fragments and only one is visible at a time. All the fragments have some <code>EditText</code> views. I wants to access edit text box values of all <code>Fragment</code>s (if <code>Fragment</code> created) when a menu button click.</p>
  
  <p>So how can I do this?</p>
