Answer 1

How you approach it will depend on what you want to achieve.

You can quite easily simulate pressing keys on a Canvas, by calling your Canvas's keyPressed(), keyReleased() and keyRepeated() methods directly.

This could be good for testing a canvas-based game, ensuring a given state is entered when certain keys are pressed on the canvas.

However, this won't allow you to control any form-based interaction, or native prompts. So you can't start the MIDlet, navigate through a LCDUI Form or List, accept a native security prompt, or edit a native TextBox. You'd need to use an emulator and some form of test scripting framework which simulates keypresses, such as Eggplant.

Answer 2

if you want to mimicking the keypressed process, just call the keypressed with the int of key as argument, for example keyPressed(-8);

Or are you trying to display the key number in the screen ?
