Splash screen with progress indicator on Blackberry - blackberry

Question

I am trying to design a splash screen with an activity indicator on it.
I am successfully creating a splash screen but my indicator is not being added to it,
it is being hidden below the image while i am setting its layout.
How can I fix this?
Here is my code:
package mypackage;
import java.util.Timer;
import java.util.TimerTask;
import net.rim.device.api.system.Application;
import net.rim.device.api.system.Bitmap;

import net.rim.device.api.ui.container.MainScreen;
//import net.rim.device.api.ui.extension.container.EyelidFieldManager;
public final class SplashScreen extends SplashScreenPage
{
public SplashScreen()
{
super(Bitmap.getBitmapResource("splash-blackberry.png"),2);
}
}
class SplashScreenPage extends MainScreen
{
VerticalFieldManager vfm= new VerticalFieldManager(Field.FIELD_VCENTER);
HorizontalFieldManager hfm = new HorizontalFieldManager(Field.FIELD_VCENTER)
{
protected void sublayout( int maxWidth, int maxHeight )
{
super.sublayout(360,60);
setExtent(360, 60);
Field field = getField(0);
layoutChild(field,140, 60);
setPositionChild(field, 100,200);
}
public void paint(Graphics graphics)
{
//Draw the background image and then call paint.
// super.paint(graphics);
//graphics.clear();
// graphics.setBackgroundColor(0x000000);
//graphics.drawBitmap(0, 0, 360, 480, popup, 0, 0);
// super.paint(graphics);
// graphics.clear();
// graphics.drawBitmap(0, 0, 360, 480, popup, 0, 0);
}
};
ActivityIndicatorView view = new ActivityIndicatorView(Field.USE_ALL_WIDTH);
ActivityIndicatorModel model = new ActivityIndicatorModel();
ActivityIndicatorController controller = new ActivityIndicatorController();
boolean notlogged = false;

//SplashScreen page is here

controller.setModel(model);
controller.setView(view);
model.setController(controller);
Bitmap bitmap = Bitmap.getBitmapResource("images.jpeg");
view.createActivityImageField(bitmap, 5, Field.FIELD_BOTTOM);
// add(view);
add(hfm);
hfm.add(view);
// add(vfm);
// vfm.add(Bitmap.getBitmapResource("splash-blackberry.png"));
this.popup = popup;
xCoord = (screenWidth - popup.getWidth()) / 2;
yCoord = (screenHeight - popup.getHeight()) / 2;
splashTask = new TimerTask() {
public void run() {
if (showSplash && !splashDisplayed) {

if (count == seconds * 15) {

In your HorizontalFieldManager that you are adding view to, you need to make sure you are calling super.paint() because it called subpaint() which will tell its child Fields (view in this case) to paint themselves. I see that you have it commented out, so you've probably been messing with that. Also, be sure that you do your background painting before you call super.paint() so you don't cover up the ActivityIndicatorView with your own painting.
Would it be possible for you to go through and clean up the code (removing the commented out code that isn't important) to a point where you would expect it to work so it is a littler easier to distinguish between "trying anything you can" code and "working" code.
