What's wrong with my main.axml?

Strangerweather

Hi guys! I'd like to ask for advice. I'm trying to set up my axml so that my action bar is collapsible, but it's no working. Could you tell me what I am doing wrong?

Here is the code: http://hastebin.com/udicalobug.xml

Many thanks for any help! :-)
