WARNING: This is a demo app for a library project. It should be of interest to Android developers only.
MultiChoiceAdapter is an implementation of ListAdapter which adds support for modal multiple choice selection as in the native Gmail app.
It provides a functionality similar to that of the CHOICE_MODE_MULTIPLE_MODAL ListView mode, but in a manner that is compatible with every version of Android from 2.x. Of course, this requires that your project uses ActionBarSherlock.
The demo sample is a showcase of the functionality of the library.
