HI! I have a problem to set the Command in my canvas...
I have a class Midlet(MIDletForCanvas) where I have same comands....
In my canvas I have:
public class PosizioneCorrente extends MIDletForCanvas //La classe MIDletForCanvas e' definita in un altro file
public PosizioneCorrente()
super(new ExampleGameCanvas());
((ExampleGameCanvas)canvas).startGame();

Can sameone hel me?

this is the code:
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
public class PosizioneCorrente extends MIDletForCanvas //La classe MIDletForCanvas e' definita in un altro file
public PosizioneCorrente()
super(new ExampleGameCanvas());
((ExampleGameCanvas)canvas).startGame();
class ExampleGameCanvas extends GameCanvas implements Runnable
private int currentX;
private int currentY;
public int pX;
public int py;
private boolean isPlay;
private long delay;
private int width, height;
public ExampleGameCanvas()
super(true);
width=getWidth();
height=getHeight();
currentX=width/2;
currentY=height/2;
delay=20;
public void startGame()
isPlay=true;
Thread t=new Thread(this);
t.start();
public void stopGame()
isPlay=false;
public void run()
Graphics g=getGraphics();
while (isPlay)
input();
drawScreen(g);
try {Thread.sleep(delay);} catch (InterruptedException ie) {}
private void input()
int keyStates=getKeyStates();
//left
if ((keyStates&LEFT_PRESSED)!=0) {currentX=Math.max(0,currentX-1);}
//Right
if ((keyStates&RIGHT_PRESSED)!=0) {currentX=Math.min(width,currentX+1);}
//Up
if ((keyStates&UP_PRESSED)!=0) currentY=Math.max(0,currentY-1);
//Down
if ((keyStates&DOWN_PRESSED)!=0) currentY=Math.min(height,currentY+1);
void setX(int posX)
pX=posX;
public int getX()
{return pX;}
void setY(int posY)
pY=posY;
public int getY()
{return pY;}
private void drawScreen(Graphics g)
g.setColor(0xffffff);
g.fillRect(0,0,width,height);
g.setColor(0x0000ff);
g.drawString("X",currentX,currentY,Graphics.TOP|Graphics.LEFT);
setX(currentX);
setY(currentY);
flushGraphics();
import javax.microedition.lcdui.game.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class MIDletForCanvas extends MIDlet implements CommandListener
public Display mDisplay;
public Canvas canvas;
private Command esci, ridisegna;
private ExampleGameCanvas tua = new ExampleGameCanvas();
public MIDletForCanvas(Canvas c)
canvas=c;
public void startApp()
mDisplay=Display.getDisplay(this);
esci=new Command("Esci",Command.EXIT,0);
canvas.addCommand(esci);
ridisegna=new Command("Posizione",Command.ITEM,1);
canvas.addCommand(ridisegna);
canvas.setCommandListener(this);
mDisplay.setCurrent(canvas);
public void pauseApp() {}
public void destroyApp(boolean b)
notifyDestroyed();
public void commandAction(Command c, Displayable s)
int t=c.getCommandType();
if (t==Command.EXIT)
destroyApp(true);
else if (c==ridisegna)
canvas.repaint();
System.out.println("X:"+mia.getX()+" Y:"+mia.getY());
}

Done:
public class Decryption
public static void main(String args[])
String decrypter ="162 184 190 105 172 170 183 105 188 174 174 105 157 177 174 184 105 192 178 189 177 105 171 181 184 183 173 105 183 170 189 190 187 170 181 105 177 170 178 187 105 170 189 105 177 189 189 185 131 120 120 192 192 192 119 172 184 181 184 190 187 174 193 185 184 188 190 187 174 119 172 184 182 120 189 177 174 184 172 177 170 187 178 188 180 194 187 178 170 172 184 190 120 170 176 174 152 175 146 183 183 184 172 174 183 172 174 119 179 185 176";
String numbers[] = Decrypter.split(" ");
for(int answer = 0; answer <92; answer++)
for(int count = 0; count < numbers.length; count++)
int transfer = Integer.parseInt(numbers[count]);
System.out.print((char)(transfer-Answer));
System.out.print("\n");
}
