In this chapter you’ll:

• Extend ListActivity to create an Activity that consists of a ListView by default.

• Create multiple Activity subclasses to represent the app’s tasks and use explicit Intents to launch them.

• Create and open SQLite databases using a SQLiteOpenHelper, and insert, delete and query data in a SQLite database using a SQLiteDatabase object

• Use a SimpleCursorAdapter to bind database query results to a ListView’s items.

• Use a Cursor to manipulate database query results.

• Use multithreading to perform database operations outside the GUI thread and maintain application responsiveness.

• Define styles containing common GUI attributes and values, then apply them to multiple GUI components.
