I am working on android application . I have implemented supported action bar in it .I
You can use the different values of android:showAsAction
property in android menu xml file..
to show all time visible menu on actionbar, you should go with android:showAsAction="always"
..
You can also use android:showAsAction="ifRoom"
but it will show the menu in action bar not always but it will show according to different screen size.
Edited
Ref: Menu items doesn't show up on the actionbar
Try with the below code then..
Hope it will help you..!!!
