Hide/show Action Bar in Android activity

I have an android activity extended from ActionBarActivity.

My Activity content ruled by state pattern. When state changes, screen also changes somehow. I need ActionBar just in one of 3 states I have. How can I hide ActionBar by default and show it only in one State of my Activity?.
