ProgressFragment

Implementation of the fragment with the ability to display indeterminate progress indicator when you are waiting for the initial data. Based on ListFragment.

ExtendedCalendarView

This project is meant for people who want to display a calendar view and show that there are events on certain days. What I did was pull out the calendar view from Google’s Calendar application.
Implementation is not the easiest though as there is a lot to it but I hope to filter out stuff that is not needed to try to make it simpler.

ProgressButton

ProgressButton is a custom progress indicator with a tiny footprint. Based on the sample code provided by Roman Nurik on Google Code. The default implementation provides a pin progress button as seen on the Android design site.
The color indicates whether it’s downloaded (blue) or not (gray). The appearance of the pin indicates whether the download is permanent (white, upright) or temporary (gray, diagonal). When state is in the process of changing, progress is indicated by a moving pie chart

Pager Sliding TabStrip

Inspired by the new 4th version of the Android Play Store, Pager Sliding TabStrip is anInteractive paging indicator widget, compatible with the ViewPager from the Android Support Library.
Try out the sample application on the Play Store.

Fading ActionBar

FadingActionBar is a library which implements the cool fading action bar effect that can be seen in the new Play Music app.
This library uses the techniques outlined by Cyril Mottier in a recent blog post.
For reasons of backwards compatibility this library relies on ActionBarSherlock. If your app uses the native action bar, there is a fork for you.

MessageBar

An Android Toast replacement, similar to the one seen in the GMail app.
Features:

• Messages are local to the Activity/Fragment the MessageBar is attached to
• Messages can be queued
• Can display a button, with a listener to react to clicks

HoloGraphLibrary

This library is an open-source set of graph types that are easy to add to your app, and in addition, look gorgeous. Themed in the much-loved Holo style of Android, the graphing library should fit in with any of your modern, standards-compliant apps.
