If you’re looking to get started creating a user interface for your app, there are various ways of getting started. You could always start from scratch, learning the entire process as you go along. In fact, that’s probably the ideal way of doing it, provided you have the time, as you’d have a deeper understanding of how things work and how to fix problems
if when they arise.
However, ain’t nobody got time to do things the long way. To help speed things along for new developers who would rather concentrate on core functionality code rather than UI layouts, XDA Senior Member AuxLV created GrilledUI, an open source streamlined library aimed at easily creating common UI layouts. As described by AuxLV:
Available UI types are: tabbed UI (TabActivity), master/metail flow (SectionActivity) and their hybrid (HybridActivity). These activity classes wrap everything you need to create your UI with just a few lines of code or even load tabs/sections and instaniate fragments from XML file. HybridActivity allows you to have tabs on phones and MDF on tablets. This way you can easily make your app tablet and phone friendly without torturing phone users with multiple activities.
Included with the library are multiple examples, a BSD license, and support for pre-ICS devices using ActionBarSherlock. Head over to the resource thread to get started and visit the Github to take a peek at the source._________
