Adapters and lists

This is just a simple demonstration of how you could handle Adapters and AdapterViews in a simple way with AndroidAnnotations.

Let's say you have a Person class:

public class Person {
	public final String firstName;
	public final String lastName;

	public Person(String firstName, String lastName) {
		this.firstName = firstName;
		this.lastName = lastName;
	}
}

and a PersonFinder interface:

public interface PersonFinder {
	List<Person> findAll();
}

You want to create a PersonListActivity that lists all the available persons. For that, you'll need a PersonListAdapter that creates the binds the data to the views, and a PersonItemView that is the view for one item in the list.

The PersonItemView will use one TextView for the first name, and one TextView for the last name:

@EViewGroup(R.layout.person_item)
public class PersonItemView extends LinearLayout {

	@ViewById
	TextView firstNameView;

	@ViewById
	TextView lastNameView;

	public PersonItemView(Context context) {
		super(context);
	}

	public PersonItemView(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	public PersonItemView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
	}

	public void bind(Person person) {
		firstNameView.setText(person.firstName);
		lastNameView.setText(person.lastName);
	}
}
