Help me........Splash Screen

The algorithm is as follows:
The program will include two MainScreen. 1 and 1 MainScreen Splashscreen MainScreen do is the main program (Here is UiApp)

When the program starts, we display Splashscreen ago, in this Splashscreen through BitmapField we add an Image containing Splashscreen want to do. At the same time will give an animated Thread sleep for 5 seconds, after 5 seconds it wake up to the main MainScreen load up.

So when the program runs it will see an image, animated 5 seconds going into the main program.

When you exit the program it self turn out to be out Home Screen of BB.


Code UiApp


import net.rim.device.api.ui.UiApplication;

* This class extends the UiApplication class, providing a
* graphical user interface.
public class UiApp extends UiApplication
* Entry point for application
* @param args Command line arguments (not used)
public static void main(String[] args)
// Create a new instance of the application and make the currently
// running thread the application's event dispatch thread.
UiApp theApp = new UiApp();

* Creates a new MyApp object
public UiApp()
// Push a screen onto the UI stack for rendering.
pushScreen(new SplashScreen(this));


Code Cubyn


import net.rim.device.api.ui.MenuItem;
import net.rim.device.api.ui.component.BitmapField;

btnLogin = new ButtonField("Đăng nhập", ButtonField.CONSUME_CLICK );

HorizontalFieldManager buttonManager = new HorizontalFieldManager(Field.FIELD_RIGHT);

btnClear.setCommand(new Command(clearHandler));
btnLogin.setCommand(new Command(loginHandler));

setTitle("Thông tin");


public void clearText() {

public void login() {
if (username.getTextLength() == 0 || password.getTextLength() == 0) {
Dialog.alert("Bạn phải nhập tên đăng nhập và mật khẩu");
else {
UiApp.getUiApplication().pushScreen(new Album());


protected void makeMenu(Menu menu, int instance) {

MenuItem loginMenu = new MenuItem(new StringProvider("Đăng nhập"), 20, 10);
loginMenu.setCommand(new Command(loginHandler));

MenuItem clearMenu = new MenuItem(new StringProvider("Xóa"), 20, 10);
clearMenu.setCommand(new Command(clearHandler));

class LoginCommandHandler extends CommandHandler{
public void execute(ReadOnlyCommandMetadata metedata, Object context){
class ClearCommandHandler extends CommandHandler{
public void execute(ReadOnlyCommandMetadata metedata, Object context){


final class SplashScreen extends MainScreen
UiApplication _app;
* Creates a new HelloWorldScreen object
SplashScreen(UiApplication app)
_app = app;
Bitmap myBitmap = Bitmap.getBitmapResource("img/spashscreen.png");
BitmapField myBitmapField = new BitmapField(myBitmap);

public void startLoading() {
Thread loadThread = new Thread() {
public void run() {
// Make sure to invokeLater to avoid problems with the event thread.
// Stay there for 5 seconds
} catch(java.lang.InterruptedException e){}

_app.invokeLater( new Runnable() {
public void run() {
_app.pushScreen(new Cubyn((SplashScreen)_app.getActiveScreen()));
