SlidingTabs

Gradle port of Google's SlidingTabLayout to display a custom ViewPager title strip as used in Google I/O Android App, Android SlidingTabsBasic Sample, and Android SlidingTabsColors Sample. It has minor modifications to work from SDK 8

Layouts

Android's EditText widget supports formatted (a.k.a., "rich text") editing. It just lacks any way for the user to supply formatting, and it does not provide much in the way of convenience methods for a developer to, say, tie in some sort of toolbar to allow users to format selections.

That's where RichEditText comes in.

RichEditText is a drop-in replacement for EditText that:

Provides an action mode on Android 4.0+ that allows users to format selected pieces of text
Provides convenience methods to allow developers to trigger formatting for selected text via other means

Text Views

Broker

A facade between executing requests and creating them. The library provides an interface for creating requests, but delegates the actual execution to RequestExecutors. It also generates REST services for you using annotation processing.

REST

ViewHolderInflater

The fastest view-injection Android library that populates View Holders. Using annotation processing, this library generates findViewById(), saves code by connecting view-related methods to your views without need to findViewById and then setOnClickListener, and some other smart features that make it amazingly easy to use.
