Android how to remove the registration on the left for the action bar icon

I have an action bar that has an icon

I want the icon to be exactly on the left side of the screen, I mean without any additions.

perhaps?

I already found this answer to delete the registration around the action bar icon on the Android 4.0+ , but I do not know if this large code is needed. and in response to this answer deletes the registration for the action bar icon throughout the application, I only need for a specific action.
