Keypressed() only working with 'cancel' key

Question

Hi! Good Day! I am trying to make a game using the gameCanvas class, everything is fine except when I try to use the keyPressed() event so that I could evaluate what keys where pressed, unfortunately only the 'Cancel' key works on my program.
I am using J2ME wireless toolkit to build and run my program. Please help, Ive searched everywhere and all I see is sample code, but when I try to use keyPRessed() it still doesnt work the way its suppose to be. Thank you. Here's my code:
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
public class WatchaWordCanvas extends GameCanvas implements Runnable {
  private boolean isPlay;   // Game Loop runs when isPlay is true
  private long delay;       // To give thread consistency
  private int currentX, currentY;  // To hold current position of the 'X'
  private int currentLocation;
  private boolean[] selectedBog = new boolean[16];
  private int staticX, staticY;
  private int bogposX, bogposY;
  private int width;        // To hold screen width
  private int height;       // To hold screen height

}Thanks in advance

Instead of the thread - Implement the keyPressed() and keyReleased() methods to keep track of events.
