I really like the 4.0 ICS Holo Light theme and would like to have it in my app to support <4.0 smartphones.
I found Android layoutlib.jar in platform folder but i
It would be better not to use the Holo theme on unsupported devices. You can do a simple trick to make your app run the Holo theme on 3.x and up, and one of the built in themes on 2.3 and below, like so:
In your manifest, use this line for your activity's theme
android:theme="@style/Theme.MyTheme"
In your res/values folder put a styles.xml file, containing
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.MyTheme" parent="@android:style/Theme.Black" />
</resources>
Create a res/values-v11 folder, and a styles.xml file in that, containing:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.MyTheme" parent="@android:style/Theme.Holo" />
</resources>
This will make Android use the Holo theme if the app is running on a device that supports it (3.x and up, which is API level 11 and up, hence the "values-v11"). This is the best solution to make your app match the phone's user interface, and use the Holo theme only wherever it's supported.
You can use Holo in Android 2.3< with this simple library : http://www.holoeverywhere.com/ Its called Holo everywhere and works fine in previous versions of android. The Library is hosted on Github.
Check ActionbarSherlock. It also provides a styled TabView. The samples directory provides a real good example for a TabView which works like a charm on Android 2.2.
