Start screen appears and App starts do not

Hello and thanks in advance.

I am trying to build a splash screen that displays a logo for 5 seconds, then returns to the main application, but the application shows the start screen or starts the main thread. I looked at the code example in the start screen and tried to imitate closely.  The model code is shown below.


import java.util.Timer;

import net.rim.device.api.system.Bitmap;import net.rim.device.api.ui.Field;import net.rim.device.api.ui.FocusChangeListener;import net.rim.device.api.ui.UiApplication;import net.rim.device.api.ui.component.BitmapField;import net.rim.device.api.ui.container.MainScreen;

public class Test extends UiApplication {  public static void main(String[] args) {      Test app = new Test();        app.enterEventDispatcher();   }

   public Test() {       SplashScreen screen = new SplashScreen();     pushScreen(screen);   } public class TestScreen extends MainScreen implements FocusChangeListener{

      public void focusChanged(Field field, int eventType) {        } }}     class SplashScreen extends MainScreen {         private UiApplication application;        private MainScreen next;      private static final Bitmap _bitmap = Bitmap.getBitmapResource("resource/logo.png");      private Timer timer = new Timer();        public SplashScreen(){        Test tmpTest = new Test();        Test.TestScreen tmpScreen = tmpTest.new TestScreen();

         this.next = tmpScreen;            this.add(new BitmapField(_bitmap));        }         public void dismiss() {           timer.schedule(new CountDown(), 5000);             timer.cancel();           application.popScreen(this);              application.pushScreen(next);          }}

The Simulator is the Curve 8330 and the api is 4.5.

Any help would be great.

Best regards and thanks again.

1. the implementation of your class of SplashScreen() is not correct.

I modified your SplashScreen() in this way:

class SplashScreen extends MainScreen
{
    private UiApplication application;
    private MainScreen next;
    private static final Bitmap _bitmap = Bitmap.getBitmapResource("resource/logo.png");
    private Timer timer = new Timer();

    public SplashScreen(UiApplication application, MainScreen next)
    {
        this.application = application;
        this.next = next;
        this.add(new BitmapField(_bitmap));
        timer.schedule(new CountDown(), 5000);

        //show this splash screen           application.pushScreen(this);
    }
    public void dismiss()
    {

        timer.cancel();
        application.popScreen(this);
        application.pushScreen(next);
    }
    private class CountDown extends TimerTask
    {
        public void run()
        {
            DismissThread dThread = new DismissThread();
            application.invokeLater(dThread);
        }
    }

    private class DismissThread implements Runnable
    {
        public void run()
        {
            dismiss();
        }
    }
}

2 and also you must call the SplashScreen of the main class in the following way:

    public Test()
    {        //the screen that will show after splash screen         TestScreen nextScreen = new TestScreen();

        new SplashScreens(this,nextScreen);
    }

    Hi William,

    Thanks for posting the query on Microsoft Community.

    If I understand correctly, you are unable to open a program as the program crashes. Don't worry, will help you with the question.

    1. What is the brand and model of the computer?

    2 does on all programs or only one?

    3. you receive an error before it crashes?

    Try to put the computer to boot and check if it helps.

  • Safari and App Store are not open. Recently updated to El Capitan 10.11.4

    Safari and App Store are not open. Safari icon will bounce back and not open. App Store comes up with "App Store close unexpectedly"

    Please read this message before doing anything.

    This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.

    The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

    Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

    Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

    The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

    Test in safe mode. Same problem?

    After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

    If you reinstalled Windows, then you can be sure that it is hardware related.

  • Everything on the left side of the screen disappeared and all programs will not recover as malware has infected my computer

    When I go to help and support, I've seen where it will take me to something in Office 2007 even if you ask the computer to find or search, he says that's not there.

    Hi windy-54,
     
    -What do you mean when you say "everything on the left side of the screen disappeared and all programs not recover"? Does this mean you "Start" menu is empty?
    -What is the exact error that you receive while you are trying to search for programs on the computer?
     
    Write us with more information pertaining to the matter to help us help you better. Meanwhile, scan your computer to clean the virus or malware that touched it.
     
    You can use the Microsoft security scanner to do the same.
    Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

    Were there any hardware or software changes made at the time the blue screen appeared?

    I suggest to close the PC and remove all devices in addition to the screen, the keyboard and the mouse.

    If the computer works without a blue screen for a reasonable period of time, you can start to add them one at a time to see if a specific device that is causing the error back.

  • How to fix iPhone 6 home & lock screen? (and apps)

    So my iPhone 6 has been left for about 5 hours and I woke up and it was hot. Applications went so quickly I them all turned off and turned my phone off, so it can cool. 10 minutes later, when it got cooler, I opened it again and there was a transparent box with an arrow circle at the bottom that I can not click and it read: "ESO; The brotherhood of darkness"on the lock screen. (Which is not part of my baggage) I have never played nor heard of this game until it continues to show on my phone. (It is not on the apple store). I tried to turn it off to restart, but it is still there, especially in the dark. I don't know if I should be concerned it shows and disappears when my light is completely upward. But in any case, is it possible to take the transparent app on my home screen and lock? (it also shows on which applications are a bit dark)

    Have you tried a forced restart (by building and maintaining home and power until the Apple appears then release buttons to finish to start)? Have you tried to restore from a back to the top? Restore like new?

    Edit: it occurs to me that you can also have suggested active apps. Settings > general > transfer & suggested Applications. Cut the two settings and see if that makes a difference.

  • Screen sharing and the Bar Menu not desired

    When you use the mode full screen with a shared computer, sharing screen menu bar down on the menu bar of the shared computer when the mouse touches the top of the screen. This makes the job difficult because it is not uncommon to hit the top of the screen when you try to use the menu bar in the remote session.

    Is it possible to change this behavior? Either by imposing a multi-seconde delay before sharing screen menu bar falls down or by requiring a special set of keys to be held down until the behavior is triggered?
