Appcelerator Alloy Widget that emulates Android's ActionBar functionality

ActionBar Clone

Summary

This widget for the Appcelerator Titanium Alloy MVC framework emulates Android's ActionBar. This Widgets provide enough functinality to become a mini-framework to build Android Apps that are consistent with Android usability guidelines.

###Example of ActionBar

Although you can access Android's native ActionBar from Titanium, you still need a way to target pre 4.0 devices. This Widget provides an easy way of ensuring that your Android App remains true to Android's usability guidelines regardless of the Android version, and providing easy-to-use theming capabilities to match your App's UI.

Configuring in your controller

// Start Configuration
$.headerbar.setParentContainer($.index);			// a reference to the window containing the widget
$.headerbar.setBackground({							// background color of the bar
	color:'#cacaca'
});
//$.headerbar.setAppIcon('/appiconcopy.png'); 		// if no icon is povided, the apps default one will be used
$.headerbar.setBlackAngle();						// color of the angle
$.headerbar.setTitle({								// the title of the containing window
	text:'Window Title',
	color:'#6f6f6f'
});
$.headerbar.setBack(function(){						// if angle is shown, what will happen uppon click.  Default to closing containing window
	$.index.close();
});
$.headerbar.hideBottomLine();						// for Holo Dark
$.headerbar.showAngle();							// show or hide
$.headerbar.setActionButtons(getExtraButtons());		// action buttons, inflater buttons and menu buttons
// End Configuration


// For clarity, I'm using a function to get the Buttons Object
// In a cross-platform scenario you'd want to have your menu options returned
// by a function so you can then decide where and how display them
function getExtraButtons(){
	return {
		visible:[
			{
				icon:'/ic_menu_copy_holo_light.png',
				title: 'Copy',

Tips

Using Android's Holo Theme

You can set your tiapp.xml to use Android's native Holo theme using the following syntax

<android xmlns:android="http://schemas.android.com/apk/res/android">
	<tool-api-level>14</tool-api-level>
	<manifest>
		<application android:theme="@android:style/Theme.Holo.Light"></application>
		<!-- You could also use @android:style/Theme.Holo -->
	</manifest>
</android>

Adding even more Android native UI patterns to your Titanium Apps

Titanium does not expose some other important Android UI patterns, such as the ViewPager. However, thanks to Titanium's capability of creating native modules, we can use the Android View Pager Module by @mudderman to add features such as Scrolling Tabs, which are very popular in Google-built apps. You can read some sample code here.

To-do

• Implement menu that will open when the "inflater" is clicked
• Add pre-defined Light and Dark themes to match Android Holo
• Add event listener on lib/buttons.js to cancel button press if finger is outside of the button area
• Add tooltip when long-pressing action button
