Why the menu items appear on the optionsMenu?

问题

Despite there are some icons associated with certain action and have no enough space in the Actionbar, they appear in the optionsMenu instead of appearing in the overflow icon.

I am inflating the actionBar with five icons each one has a specific functionality "Please refer to the XML file below", the items which have the android:showAsAction=never I expect them to implicitly reside inside the overflow icon on the actionBar, but when I run the App, any item with the property android:showAsAction=never instead it appears in the optionsMenu. Why that happens? and I hope i explained the problem clearly.

Update:

Simply, I want, if there is no space for the icon to be placed on the ActionBar, They should be placed inside the overflow icon as shown in the image " the icon with three vertical dots over each other".

To Note:

I am using Galaxy Note3

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.action_bar_activity_test00, menu);
    return super.onCreateOptionsMenu(menu);
