I'm using "setMenuVisibility"-Method for resolving this Problem. As every Fragment can have actionbar-items this is the part where you can determine which Fragment is currently visible to the user.

@Override
public void setMenuVisibility(final boolean visible) {
    super.setMenuVisibility(visible);
    if (!visible) {
        //not visible anymore
    }else{
        yay visible to the user
    }
}
