Blackberry 启动屏幕问题

当我实例化应用程序时，我需要显示一个启动屏幕，我基于blackberry-develpers-KnowlWebase（）为启动屏幕编写了一个类

我的问题是splashscreen只在一个deley之后出现，我如何解决它，如果有人有想法请帮助我，谢谢

class Test extends MainScreen{

Test(){

UiApplication.getUiApplication().invokeLater(new Runnable() 
        {
            public void run() {
                UiApplication app=(UiApplication)getApplication();

                Bitmap image = Bitmap.getBitmapResource("splah.png");
                ListView listView = new ListView();
                new SplashScreen(app, listView );

}

}

尝试同步（UiApplication.getEventLock（））。它比调用器快

Test(){
synchronized (UiApplication.getEventLock()) {
UiApplication app=(UiApplication)getApplication();
Bitmap image = Bitmap.getBitmapResource("splah.png");
ListView listView = new ListView();
new SplashScreen(app, listView );

}

}
