CommonJS module providing cross-platform UI elements for Titanium Alloy. By adding module="xp.ui" to any tag in an Alloy view, this module will become the factory instead of Ti.UI, allowing it do provide emulate views and behavior when it is not available for the target platform.

Available tags

  • NavigationWindow

    Emulates the Ti.UI.iOS.NavigationWindow for Android.

  • Window

    Returns a Ti.UI.Window on iOS and Ti.UI.View on others.

  • TextArea

    Emulates Android's hintText property for iOS.

  • Label

    Emulates Android's html property for iOS using ti-html2as

  • TextField

    Disabled Android's autofocus on the first TextField.

Alloy does a great job at supporting single-codebase cross platform apps by providing conditional tags and constants, but you still have to actually use these to code around the platform differences.

How to use it

  1. Download xp.ui.js to app/lib/xp.ui.js.
  2. Add module="xp.ui" to the element you want to use this library instead of Ti.UI to create the view.

Tag: Label

For iOS, and only if you pass a html property, it will parse the HTML to an Attributed String using te nl.fokkezb.html2as module which you need to have installed as well.

Since the nl.fokkezb.html2as module is async, the label will first return empty and the attributed string will be set as soon as the HTML is parsed. You will only notice this on slow devices with large HTML.


    <Label module="xp.ui" html="<font size=17>Hello <b>Bold</b> <font color=#FF0000>World!</font></font>" />

Tag: TextArea

For some reason, on iOS a TextArea doesn't have a hintText property. This module adds event listeners for focus and blur to change the color and value to emulate the same behavior as a TextField has.

Tag: Window

For some modules, like NappDrawer, you need to have a Window on iOS and a View on Android. The module does exactly this.

Tag: NavigationWindow

For Android, it creates and returns an intermediate object that exposes Ti.UI.iOS.NavigationWindow-like openWindow and closeWindow methods. Two more open and close methods will act on the root window wrapped by the NavigationWindow tags, giving exact the same behavior as on iOS.

Example code

  <NavigationWindow module="xp.ui">
      <Label>Hello World</Label>

Swipe to go back

Unless you set the NavigationWindow's swipeBack attribute to false or pass this as an option to openWindow, the module will add a swipe-eventlistener to close the window when the user swipes to the right, just like it does on iOS7. For Android, it adds slide_in_left and slide_out_right enter/exit animations unless you pass animated: false as an option for openWindow.

Action Bar

If you target Android SDK 11 or higher the module will automatically add the up arrow to the action bar of all but the first window. Clicking on the home icon or arrow will close the window. You can disable this by setting the NavigationWindow's displayHomeAsUp attribute to false or passing this as an option to openWindow.

Tag: TextField

On Android, this will blur the textfield to prevent auto focus.
