Log Message

Enhancement: ApiDemos - App - Dialog - AlertDialog with MultipleChoices backed by Cursor

Added an example for using AlertDialog in Multichoice mode backed up by Cursor. This example can be used to test the following bug: http://code.google.com/p/android/issues/detail?id=955

AMEND:
Added a Toast to display readonly status of cursor, so data will not be updated.
Removed empty code blocks, which did nothing.

Change Summary

• modified: samples/ApiDemos/res/layout/alert_dialog.xml
• modified: samples/ApiDemos/res/values/strings.xml
• modified: samples/ApiDemos/src/com/example/android/apis/app/AlertDialogSamples.java
