title: Reload fragment if current tab is clicked again?
body: <p>To navigate in my Android application I use <code>ActionBar.NAVIGATION_MODE_TABS</code>. The content in one of the tabs is changing quite fast.</p>
  
  <p>A user should be able to reload the tab by touching the same item in the action bar again.
  Currently the tab content is cached by <code>ViewPager</code> and therefore not refreshed if a user clicks on the tab.</p>
  
  <p>As <code>TabListener.onTabReselected(...)</code> is fired even if the current tab is already shown, it may be the starting point of a solution.</p>
