2  Java Game APIs & Engines / J2ME / Why my Back-Button won't work? on: 2004-05-28 16:58:26
Here's a little program that takes me from a menu list to a form, and back.
But can you tell me why my Back-Button won't work?

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import java.util.*;
public class Testing extends MIDlet implements CommandListener {
   private Command exitCommand   = new Command("Exit", Command.EXIT, 2);
   private Command goCommand     = new Command("Go", Command.OK, 2);
   private Command backCommand   = new Command("Back", Command.BACK, 2);
   private Display display;
   private Alert resultAlert;
   private List list;
   public static final String[] items = {"Choice 1", "Choice 2", "Choice 3", "Choice 4"};
   public Testing()  {
       display = Display.getDisplay(this);
       list = new List("", List.IMPLICIT, items, null);
       list.addCommand(exitCommand);
       list.addCommand(goCommand);
       list.setCommandListener(this);
   }
   public void startApp() throws MIDletStateChangeException {
       display.setCurrent(list);
   }
   public void pauseApp() {
   }
   public void destroyApp(boolean unconditional) {
   }
   public void commandAction(Command c, Displayable s) {
       int len, i;
       if (c == exitCommand) {
           destroyApp(false);
           notifyDestroyed();
       }  else if (c == goCommand) {
           Form resultSet = new Form("Results of Your Search");
           String[] strings = {"Here is a page", "written by a sage"};
           len = strings.length;
           for (i=0; i<len; i++ ) {
               resultSet.append(strings + "\n");
           }
           resultSet.addCommand(backCommand);
           display.setCurrent(resultSet);
       }
   }
}
