Please have a look at the following code

import javax.microedition.midlet.*;

/**

public class Midlet extends MIDlet{
private Form f;
private Display d;
private Command start,stop;
private Thread t;
public Midlet()
{
t = new Thread(new TurnLightOn());
}
public void startApp()
{
f = new Form("Back Light On");
d = Display.getDisplay(this);
d.setCurrent(f);
start = new Command("Turn On",Command.OK,0);
stop = new Command("Turn Off",Command.OK,1);
f.addCommand(start);
f.setCommandListener(new Action());
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional)
{
this.notifyDestroyed();
}
private class Action implements CommandListener
{
public void commandAction(Command c, Displayable dis)
{
f.append("Light is Turnning On");
t.start();
}
}
private class ActionOff implements CommandListener
{
public void commandAction(Command c, Displayable dis)
{
}
}
private class TurnLightOn implements Runnable
{
public void run()
{
f.append("Working");
for(int i=0;i<100;i++)
{
try
{
d.flashBacklight(200);
d.vibrate(200);
Thread.sleep(1000);
}
catch (InterruptedException ex)
{
ex.printStackTrace();
}
}
}
}
}
First, Please note I am a 100% newbie to Java Mobile.
In here, I am making the light on and vibrate on when user click the button. However, I really wanted to create a SOS application which turn the whole screen into white, and go to black, like that, in the thread. I guess I didn't achieve that by this app because even the lights are on, the buttons are still there. I tried to turn the "Form" color to "white" but it seems like JME has no "Color" class! Please help!
