ListView Views through ListActivity

--see (Books/Android/Source Code/BasicViews5)

ListView (android.widget.ListView) is used to display list of items in a vertically scrolling list.

• SpinnerView is a subclass ---here have a spinner instead of scrolling list.

ListActivity - this is an subclass of Activity that includes a ListView in it automatically

• Create Activity class that extends ListActivity

public class BasicViews5Activity extends ListActivity {

• Setup of Get the Strings that represent the Items in the List here we are going to store it in an array of strings called presidents[]

String[] presidents = {"Dwight D Eisenhower", ********};

• in onCreate(*) of our ListActivity setup the ListAdapter using setListAdapter

  setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, presidents));
  

• Implement the onListItemClick() method that is an eventhandler code to respond when an Item in ListActivity's built-in ListView is selected
  • See full example below
