저는 BlackBerry 응용 프로그램을 만들고 있는데, 이제 이미지 버튼을 클릭 할 때 애니메이션을 제공하려고합니다. 내 응용 프로그램에서는 스플래시 화면을 사용하고 로그인 페이지가 표시됩니다. 로그인 페이지의 제출 버튼을 클릭하면 홈 스크린이 표시되고 거기에 슬라이드 애니메이션을 표시하려고합니다. 내 페이지 슬라이드 애니메이션을 블랙 베리에주는 방법은 무엇입니까?

내 코드입니다 :public class LoginPage extends MainScreen implements FieldChangeListener {

labeluser = new LabelField("Enter Username : ", Field.FIELD_LEFT); labeluser.setMargin(10, 0, 0, 10); labeluser.setColor(Color.BLACK);

슬라이드 애니메이션을 구현하는 방법을 제안 해주십시오.
감사합니다.
