I found the following interesting articles this morning with pointers to sample code for Android UI:

• Pinned Header List View–This is interesting list view code appearing in the Devoxx 2010 sample application, which is a good example of Android UI Patterns use.
• ViewPager meets Swipey Tabs–This is interesting UI navigation code appearing in the Android Playground sample code, which is another good example of advanced Android UI patterns.

In doing a quick search on new Android user interface patterns, I was pleasant surprised with a plethora of resources. First, anyone wanting to keep up to date with what is happening on the Android platform should check the Android UI Patterns Blog. From there you will get a pointer to the following code projects and resources:

• android-ui-patterns code project–This code sample resource is mentioned in an article about implementing the Dashboard and Action Bar patterns.
• Dashboard Pattern Source–This is a part of source code for IoSched written by Roman Nurik.
• IoSched–IoSched is a source code project that is updated every year for the Google I/O Conference for managing access to classes at the conference. Quite cool.
• Styling Android–This is a great blog that covers topics related to styling Android user interfaces, including the discussion of using graphical elements vs. layout techniques.
• Dynamic List Implementation–This is an implementation of an “endless list adapter,” allowing for an ever-expanding list that can be refreshed using the android-pulltorefresh project by Johan Nilsson.
• Android View Flow–This is a great source of sample code for scrolling through paged views. The new Android Market and Google+ apps use this.

These are just a few of the resources found, and links on these pages provide a pathway to many more.

This article is the best one I have seen that discusses the actual real-world differences between developing actual applications for both iOS and Android.

This is a quick post to point to a cool Android UI Widget that can be found here. It provide a pager view similar to a built-in iOS control.

Another great control I found is here. This control provides support for long, long lists in Android applications similar to the pull-down list work in Three20.

Finally, this Android Patterns site provides a good view of how to build great Android applications.

This article is a great introduction to the Android concept of Intents and Intent Filters.

This article provides great information regarding multithreaded access to SQLite databases. For applications with large amounts of data stored on the device that can be queried by the user, this is important when considering application responsiveness.
