SuperScrollableView

app.js

var win = Ti.UI.createWindow({
	rightNavButton: rightButton = Ti.UI.createButton({title:'next'}),
	leftNavButton: leftButton = Ti.UI.createButton({title:'prev'})
});

var SuperScrollableView = function(a){
	a = a || {};	
	var view = Ti.UI.createView({
		layout:'horizontal',
		top:0,
		bottom:0,
		left:0,
		width:a.views[0].width*a.views.length,
		views:a.views
	});
	for(var i = 0; i < a.views.length; i++){
		a.views[i].left = 0;
		view.add(a.views[i]);
	}
	view.scrollToView = function(i,args){
		args = args || {};

		if(args.animated == true){
			view.animate({left:-(a.views[i].width*i)});
		} else {
			view.left = -(a.views[i].width*i);
		}
		view.currentPage = i;
		// a.views[i].fireEvent('focus');
	};
	view.currentPage = 0;
	return view;

// usage:

var width = win.size.width;
var height = win.size.height - 44; // minus nav bar

var myView = SuperScrollableView({
	views:[ 
		Ti.UI.createView({
			width:width,
			height:height,
			backgroundColor:'red'
		}),
		Ti.UI.createView({
			width:width,
			height:height,
			backgroundColor:'green'
		}),
		Ti.UI.createView({
			width:width,
			height:height,
			backgroundColor:'blue'
		}),
		Ti.UI.createView({
			width:width,
			height:height,
			backgroundColor:'yellow'
		})
	]
});


win.add(myView);

var x = 0;

leftButton.addEventListener('click', function(){
	--x;
	if(x < 0){ x = 0;}
	myView.scrollToView(x,{animated:true});
});
rightButton.addEventListener('click', function(){
	++x;
	if(x > myView.views.length-1){ x = myView.views.length;}
	myView.scrollToView(x,{animated:true});
});

win.open({modal:true});

Just a comment, this code has been tested in Titanium 1.8. The "view.size.width" and "view.size.height" might not work in Titanium 2.0
