Push and Pop Screen in Blackberry

Apparently this is the Best example I found to push and Pop Screen. Everything is working so far. Only issue having after adding the second but which can not navigate to other screen. There got to be a way to do it.

I am looking for the other excellent Article which might have the solution.

Found another Solution and have to try this:

The following function should fix my screen issue

1. public void switchScreen(final Screen nextScreen) {
2. final UiApplication ui = UiApplication.getUiApplication();
3. final Screen currentScreen = ui.getActiveScreen();
5. if (UiApplication.isEventDispatchThread()) {
6. ui.popScreen(currentScreen);
7. ui.pushScreen(nextScreen);
8. } else {
9. ui.invokeLater(new Runnable() {
10. public void run() {
11. ui.popScreen(currentScreen);
12. ui.pushScreen(nextScreen);
13. }
14. });
15. }
16. }
