How to put the multi-window button in the actionbar?

Question

Android

On "samsungs" there is a multi-window mode, earlier, on HOLO styles everything was fine, the button was located in the action bar, but when I replaced it with AppCompat (presumably at that moment), the button moved to the bottom of the page.
Here are the screenshots:
1. The problem is, the button overlaps the send message button
2. This is how this button looks in the interface in general
3. How it was before
How to return the button back to the action bar?
