Enter data, view it back and using List in J2ME

Hello friends, todays’ story is; first you enter your name in a form, then after you click on a command you will be able to see your name with another message, after that you will be provided selection list to choose. :-( I know you are confused about what I am talking. Don’t worry just see below images to get an idea about our next mobile application.

First Two ViewsToday you will be able to identify below classes;

  • List
  • String
  • TextBox

Last Two Interfaces

Lets see the code which create above interfaces and the functions.

package anuja;

import javax.microedition.lcdui.Choice;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.lcdui.List;
import javax.microedition.lcdui.TextBox;
import javax.microedition.lcdui.TextField;
import javax.microedition.midlet.MIDlet;

 * @author Anuja
public class SelectYourChoice extends MIDlet implements CommandListener {
    private Display display;
    private Form selectForm;
    private TextField nameTxtFld;
    private List choiceList;
    private Command exitCmd;
    private Command nextCmd;
    private TextBox nameTxtBox;
    private String yourName;
    private Command goCmd;

    public void startApp() {
        display = Display.getDisplay(this);
        selectForm = new Form("Select Your Choice");
        nameTxtFld = new TextField("Enter Your Name", "", 30, TextField.ANY);

        exitCmd = new Command("Exit", Command.EXIT, 7);
        nextCmd = new Command("Ok", Command.OK, 4);


        choiceList = new List("Select a language", Choice.MULTIPLE);
        choiceList.append("Java", null);
        choiceList.append("C++", null);
        choiceList.append("PHP", null);


        nameTxtBox = new TextBox("Welcome", "", 300, TextField.ANY);
        goCmd = new Command("Go", Command.OK, 4);



    public void pauseApp() {

    public void destroyApp(boolean unconditional) {

    public void commandAction(Command c, Displayable d) {
        if(c == exitCmd){
        }else if(c == nextCmd){
            yourName = nameTxtFld.getString();
            nameTxtBox.setString("Hi " + yourName + "\n Choose your favorite programming language next");
        }else if(c == goCmd){

The things you have to remember is, you can’t append a List in to Form. Another thing that I got stuck is we can’t append Form components like TextField cannot append to a List also. But we can add Commands to a List as I have done. Lets see the reasons for those in a future post. Thanks for reading🙂
