Java ME - Multiple forms, moving from one screen to the next

Question

Hi there, i'm using Java Micro Edition and i'm trying to create a simple login form with a record store. When the user enters the details i'd like to check them against the ones stored and then move onto another screen like a welcome area.

I have a feeling its something to do with the form element and switching between it but i cant seem to get anywhere with google grr

thanks in advance!

Answer 1

try this

form = new Form("login");
                form.addCommand(getExitCommand());
                form.addCommand(getOkCommand());
                form.setCommandListener(this);

    public void commandAction(Command command, Displayable displayable) {

            if (displayable == form) {
                if (command == exitCommand) {

                    exitMIDlet();

                } else if (command == okCommand) {

                    display.setCurrent(getWelcomeForm());


                }
            } else if (displayable == form1) {
                if (command == backCommand) {



                }
            }

        }

Answer 2

display is something that should be created in the constructor and also above it i.e.

public class YourMidlet extends MIDlet implements CommandListener {

    private Display display;
    private Form form1;
    private Form form2;

public YourMidlet 
{
 display = Display.getDisplay(this);
 form 1 = new Form("hello form this is form 1");
 form 2 = new Form("hello form 2");
 display.setCurrent(form1);
}

you then do:

display.setCurrent(form2);

to switch to form 2
