accessing Inner class while creating BitmapField & adding it in HorizontalFieldManager - blackberry

Question

I'm creating a inner class in a method. After that I am accessing some statements like,
public class Test extends MainScreen
{
HorizontalFieldManager hfm;
Bitmap bitmap[] = new Bitmap[100];
BitmapField[] bitmapField = new BitmapField[100];
int countBitmap = 0;
Test()
{
VerticalFieldManager vfm_Main = new VerticalFieldManager();
hfm = new HorizontalFieldManager(HorizontalFieldManager.USE_ALL_WIDTH);
vfm_Main.add(hfm);
add(vfm_Main);
}
void drawBitmap()
{
bitmap[countBitmap] = new Bitmap(100, 100);
bitmapField[countBitmap] = new BitmapField(bitmap[countBitmap]){
public void paint(Graphics g)
{
................
................
g.drawLine(x1,y1,x2,y2);
}
}
synchronized(UiApplication.getEventLock())
{
for(int i = 0 ; i < bitmapField.length; i++)
{
if(bitmapField[i] != null)
{
bitmapField[i].setBitmap(bitmap[i]);
}
}
hfm.add(bitmapField[countBitmap]);
countBitmap++;
But here the problem is after creating the bitmap & before creating the bitmapField, control goes to
synchronized(UiApplication.getEventLock()){hfm.add(bitmapField[countBitmap]); }
So before creating the bitmapField, it adds it in hfm.
So the output is coming like "Everytime a new BitmapField is added in hfm (means at the same position by replacing the previous one)". But I want the BitmapFields come next to each other in hfm.
How to do it?
Any solution why the control goes first to hfm.add() before the new bitmapField() inner class?

Answer 1

first of all, several suggestions about code:
see no reason using synchronized since it's UI thread
don't setBitmap, bitmap is already passed to BitmapField constructor
actually all BitmapFields come next to each other in hfm, to make it clear, I've add number to each one.
if you want some custom constructor or new fields in BitmapField, it's better to create new class as an extension of BitmapField
class TestScr extends MainScreen {
HorizontalFieldManager hfm;
Bitmap bitmap[] = new Bitmap[100];
BitmapField[] bitmapField = new BitmapField[100];
TestScr() {
hfm = new HorizontalFieldManager();
add(hfm);
drawBitmap();
}
void drawBitmap() {
for (int i = 0; i < 5; i++) {
bitmap[i] = new Bitmap(50, 50);
Graphics graphics = new Graphics(bitmap[i]);
graphics.setColor(Color.RED);
String number = Integer.toString(i);
Font font = graphics.getFont().derive(Font.BOLD, 40, Ui.UNITS_px);
graphics.setFont(font);
int textWidth = graphics.getFont().getAdvance(number);
int textHeight = graphics.getFont().getHeight();
int x = (bitmap[i].getWidth() - textWidth) / 2;
int y = (bitmap[i].getHeight() - textHeight) / 2;
graphics.drawText(number, x, y);
bitmapField[i] = new BitmapField(bitmap[i]) {
public void paint(Graphics g) {
super.paint(g);
int width = getWidth() - 1;
int height = getHeight() - 1;
g.setColor(Color.GREEN);
g.drawLine(0, 0, width, 0);
g.drawLine(width, 0, width, height);
g.drawLine(width, height, 0, height);
g.drawLine(0, height, 0, 0);
}
};
hfm.add(bitmapField[i]);
}
}
}
