Problem installing ActionBar for AndroidActionView

I am trying to use setActionView from ActionBar in ICS

It seems like it should be straightforward, but somehow I don't get the layout alignment that I hope for. As you can see in the image below, the target icon is in the right direction inside the layout. But when I setActionBar (progress), the progress view always aligns to the right, no matter what I try.

before clicking the menu itemafter clicking the menu item

Here are 2 states, before and after clicking on a menu item. As you can see, viewing progress is always aligned to the right. I tried changing the gravity parameters in my xml progress layout from left to right to the center, and all I can change seems to be changing nothing.

I did not find any information about this problem, so I think I should be doing something wrong.
