An Android Parallax ListView item (this effect inspired by sound cloud android app).

Android comes with a few "wrapper" classes, like CursorWrapper, that make it relatively easy for you to add just a bit of functionality to an existing object. The wrapper delegates all behaviors to the wrapped object; you just override the specific behaviors you need. This works well in cases where there are many possible underlying implementations, so you could not robustly accomplish these ends by subclassing.

Android lacks such a wrapper for ListAdapter, though. There is a WrappedListAdapter entry in the SDK, but it is an interface, not an implementation.

So, CWAC offers an AdapterWrapper to fill this void.

Sometimes, you want your users to pick a color. A simple approach is to give the user a fixed roster of a handful of colors -- easy, but limited. A fancy approach is to use some form of color wheel, but these can be difficult to use on a touchscreen and perhaps impossible without a touchscreen.

ColorMixer is a widget that provides a simple set of SeekBars to let the user mix red, green, and blue to pick an arbitrary color. It is not very big, so it is easy to fit on a form, and it is still fairly finger-friendly.

It is also packaged as a dialog (ColorMixerDialog), a dialog-themed activity (ColorMixerActivity), and a preference (ColorPreference).

This project has a handful of Android containers (ViewGroup implementations) designed to handle specific scenarios:

• AspectLockedFrameLayout that resizes itself, and its children, to fit within a specific aspect ratio
• MirroringFrameLayout and an associated Mirror that duplicates and scales the contents of the MirroringFrameLayout onto the Mirror

Android BounceProgressBar Widget.
