Blackberry (Java) - Can't get KeyListener to work
- by paullb
I am trying to get the KeyListener working for Blackberry, but none of the Dialogs pop up indicating that a key has been pressed (see code below, each action has a dialog popup in them).
Any ideas on what i might be doing wrong?
public class CityInfo extends UiApplication implements KeyListener
{
static CityInfo application;
public static void main(String[] args)
{
//create a new instance of the application
//and start the application on the event thread
application.enterEventDispatcher();
}
public CityInfo()
{
//display a new screen
application = new CityInfo();
pushScreen(new WorkflowDisplayScreen());
this.addKeyListener(this);
}
public boolean keyChar(char arg0, int arg1, int arg2) {
// TODO Auto-generated method stub
Dialog.alert("key pressed : " + arg0);
return true;
}
public boolean keyDown(int keycode, int time) {
// TODO Auto-generated method stub
Dialog.alert("keyDown : " + keycode);
return false;
}
public boolean keyRepeat(int keycode, int time) {
// TODO Auto-generated method stub
Dialog.alert("keyRepeat : " + keycode);
return false;
}
public boolean keyStatus(int keycode, int time) {
// TODO Auto-generated method stub
Dialog.alert("keyStatus : " + keycode);
return false;
}
public boolean keyUp(int keycode, int time) {
Dialog.alert("keyUp : " + keycode);
// TODO Auto-generated method stub
return false;
}
}
I also tried implementing keyChar on the MainScreen class but that did not yield any results either.
