Listen to key stroke during phone dialing

[ Edited ]

I would like to register a KeyListener to capture the number pressed during a phone dialing. Here is my sample code:

 

public class MyApp extends UiApplication{

public registerListeners(){
setAcceptEvents(true);
enableKeyUpEvents(true);

....

addKeyListener(new KeyListener(){
public boolean keyChar(char key, int status, int time) {
...
return false;
}
});
}

public static void main(String args[]){
MyApp alert = new MyApp();
if( args.length > 0 && args[ 0 ].equals( "autostartup" ) )
{
alert.registerListeners();
alert.enterEventDispatcher();
}
else
{
alert.enterEventDispatcher();
}

}
}

 

However, while dialing a phone number, my listener never get called. I can verify that the application is running in the background. Any ideas?

 

I am testing it on BlackBerry 8100 simulator with JDE4.2.0

 

Thanks.

 

Patrick

Re: Listen to key stroke during phone dialing

Your KeyListener will only capture keys when your application is in the foreground.  Background applications are not able to capture key presses or trackball/wheel movement.
