title: onClickListener does not work in fragment
body: <p>I've got some problems with the onClicklistener in the fragment. If I click on the button nothing happens at all. I get neither a message from the onClicklistener in Logcat nor does a Toast appear on the screen, but I can't find the error in the code. Any ideas?</p>
  
  <p>I'd appreciate any help! Thanks a lot! And sorry for my bad english</p>
