Answer 1

the code is:
package componentes;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class InterfazMid extends MIDlet implements CommandListener {
private Display display;
private List menu;
private List lista;
private TextBox cajaTexto;
private Form form;
private DateField campoFecha;
private Gauge indicador;
private TextField campoTexto;
private Ticker ticker;
private Alert aviso;
private Image imagen;
private Command atras;
private Command menuPrincipal;
private Command salir;
String menuActual = null;
public InterfazMid() {
form = new Form( "Formulario" );
indicador = new Gauge( "Indicador",false,50,20 );
campoTexto = new TextField( "Campo de texto","abc",40,0 );
ticker = new Ticker( "Componentes de la intefaz MIDP" );
aviso = new Alert( "Aviso Sonoro" );
imagen = Image.createImage( "/error.png" );
} catch( Exception e ) {}
atras = new Command( "Atr�s",Command.BACK,0 );
menuPrincipal = new Command( "Men� Ppal",Command.SCREEN,1 );
salir = new Command( "Salir",Command.STOP,2 );
protected void startApp() {
display = Display.getDisplay( this );
menu = new List( "Interfaz MIDP",Choice.IMPLICIT );
menu.append( "Caja de texto",null );
menu.append( "Fecha",null );
menu.append( "Lista",null );
menu.append( "Aviso",null );
menu.append( "Formulario",null );
menu.addCommand( salir );
menu.setCommandListener( this );
menu.setTicker( ticker );
mainMenu();
protected void pauseApp() {}
protected void destroyApp( boolean flag ) {}
public void mainMenu() {
menuActual = "Men� Ppal";
display.setCurrent( menu );
public void testTextBox() {
cajaTexto = new TextBox( "Teclea algo:","",10,TextField.ANY );
cajaTexto.setTicker( new Ticker("Probando TextBox") );
cajaTexto.addCommand( atras );
cajaTexto.setCommandListener( this );
cajaTexto.setString( "ABC" );
display.setCurrent( cajaTexto );
menuActual = "texto";
public void testList() {
lista = new List( "Seleciona:",Choice.MULTIPLE );
lista.setTicker( new Ticker("Probando List") );
lista.addCommand( atras );
lista.setCommandListener( this );
lista.append( "Opci�n 1",null );
lista.append( "Opci�n 2",null );
lista.append( "Opci�n 3",null );
lista.append( "Opci�n 4",null );
display.setCurrent(lista);
menuActual = "lista";
public void testAlert() {
aviso.setType( AlertType.ERROR );
aviso.setImage( imagen );
aviso.setString( " ** ERROR **" );
display.setCurrent( aviso );
public void testDate() {
java.util.Date fecha = new java.util.Date();
campoFecha = new DateField( "Hoy es: ",DateField.DATE );
campoFecha.setDate( fecha );
Form f = new Form( "Fecha" );
f.append( campoFecha );
f.addCommand( atras );
f.setCommandListener( this );
display.setCurrent( f );
menuActual = "fecha";
public void testForm() {
form.append( campoTexto );
form.append( indicador );
form.addCommand( atras );
form.setCommandListener( this );
display.setCurrent( form );
menuActual = "form";
public void commandAction( Command c,Displayable d ) {
String label = c.getLabel();
if( label.equals("Salir") ) {
destroyApp( true );
notifyDestroyed();
else if (label.equals("Atr�s")) {
if( menuActual.equals( "lista" ) ||
menuActual.equals( "texto" ) ||
menuActual.equals( "fecha" ) ||
menuActual.equals( "form" ) ) {
mainMenu();
else {
List l = (List)display.getCurrent();
switch( l.getSelectedIndex() ) {
case 0:
testTextBox();
break;
case 1:
testDate();
break;
case 2:
testList();
break;
case 3:
testAlert();
break;
case 4:
testForm();
break;
the code is so simple. i think that the problem is on the j2me wirless toolkit but i don't know.
thank you
bye
