title: How to hide action bar for fragment?
body: <p>How can I hide action bar for certain fragment?
  I have searched for the answer at stackoverflow, but I have only found a solution, which involves disabling action bar for main activity in android manifest. Since I need to disable action bar for one fragment, this is not an option.
  Any ideas? Thanks.</p>
