Using ActionBarExtras (https://github.com/ricardoalcocer/actionbarextras)

README.md

1. Grab the latest version of the module from https://github.com/ricardoalcocer/actionbarextras/tree/master/dist
2. Create a new Alloy project and use this file as index.js. This code is using the Chunkfive.otf custom font, which you can download for free from http://www.fontsquirrel.com/fonts/download/ChunkFive and save it to app/assets/android/fonts

index.js

function doClick(e) {
    alert($.label.text);
}

// load the module
var abextras = require('com.alcoapps.actionbarextras');

$.index.addEventListener('open',function(evt){

	// set extras once the Activity is available
	abextras.title = "ActionbarExtras";
	abextras.titleFont = "Chunkfive.otf";
	abextras.titleColor="#840505";
	abextras.subtitle = "for some extra action";
	abextras.subtitleFont = "Chunkfive.otf";		
	abextras.subtitleColor="#562A2A";
	abextras.backgroundColor="#F49127"

	// disable the App Icon
	//abextras.setDisableIcon();

	// now set the menus
	evt.source.activity.onCreateOptionsMenu = function(e){

		// aboutBtn and creditsBtn will be displayed in the menu overflow
		aboutBtn = e.menu.add({
			title : "About",
			showAsAction : Ti.Android.SHOW_AS_ACTION_NEVER
		});

		aboutBtn.addEventListener("click", function(e) {
			console.log('Clicked on About')
		});

		creditsBtn = e.menu.add({
			title : "Credits",
			showAsAction : Ti.Android.SHOW_AS_ACTION_NEVER
		});

		creditsBtn.addEventListener("click", function(e) {
			console.log('Clicked on Credits')
		});


		// create the Share intent and add it to the ActionBar
	    var intent = Ti.Android.createIntent({
	       action: Ti.Android.ACTION_SEND,
	       type: 'text/plain'
	    });
	    intent.putExtra(Ti.Android.EXTRA_TEXT, 'Hello world!');

	    abextras.addShareAction({
	        menu: e.menu,
	        intent: intent
	    });
	};
})

$.index.open();
