I have written the following code here the background image is displaying but the image did not cover the full background
private Bitmap background;
int mWidth = Display.getWidth();
int mHeight = Display.getHeight();
public MyScreen()
{
// Set the displayed title of the screen
//backgroundBitmap = Bitmap.getBitmapResource("slidimage.png");
final Bitmap background = Bitmap.getBitmapResource("slidimage.png");
HorizontalFieldManager vfm = new HorizontalFieldManager(USE_ALL_HEIGHT | USE_ALL_WIDTH) {
public void paint(Graphics g) {
g.drawBitmap(0, 0,mWidth, mHeight, background, 0, 0);
super.paint(g);
}
};
add(vfm);
public static Bitmap resizeBitmap(Bitmap image, int width, int height)
{
int rgb[] = new int[image.getWidth()*image.getHeight()];
image.getARGB(rgb, 0, image.getWidth(), 0, 0, image.getWidth(), image.getHeight());
int rgb2[] = rescaleArray(rgb, image.getWidth(), image.getHeight(), width, height);
Bitmap temp2 = new Bitmap(width, height);
temp2.setARGB(rgb2, 0, width, 0, 0, width, height);
return temp2;
}
You can use the above method to resize the image
just pass the image to be resized and its width and height .
and the function will return the resized image .
where rescale Array is the below method
private static int[] rescaleArray(int[] ini, int x, int y, int x2, int y2)
{
int out[] = new int[x2*y2];
for (int yy = 0; yy < y2; yy++)
{
int dy = yy * y / y2;
for (int xx = 0; xx < x2; xx++)
{
int dx = xx * x / x2;
out[(x2 * yy) + xx] = ini[(x * dy) + dx];
}
}
return out;
}

I tried set with this.setRowHeight(i, highest + 10);. It return wrong size of height and still every row same height.
I believe there was some tricky part and blackberry does not support for set different row height.
To set dynamic row height, it must call again in listfieldcallback()

This is my custom layout which was same as android linear layout
public class Custom_TopField extends VerticalFieldManager {
private static final int FIELD_HEIGHT = 70;
private String _text;
Custom_TopField(int color, String text) {
super(Manager.NO_VERTICAL_SCROLL);
_text = text;
Background background = BackgroundFactory.createSolidBackground(color);
setBackground(background);
}
protected void sublayout(int width, int height) {
width = Math.min(width, getPreferredWidth());
height = Math.min(height, getPreferredHeight());
setExtent(width, height);
}
public int getPreferredHeight() {
return FIELD_HEIGHT;
}
public int getPreferredWidth() {
return Display.getWidth();
}
public void paint(Graphics graphics) {
int rectHeight = getPreferredHeight();
int rectWidth = getPreferredWidth();
Font font = Font.getDefault().derive(Font.BOLD, 65);
graphics.drawRect(0, 0, rectWidth, rectHeight);
graphics.drawText(_text, rectWidth / 2, 10);
graphics.setFont(font);
graphics.setColor(Color.WHITE);
super.paint(graphics);
}
}
Output = background red and font = black
What I want is background red, font white, font size 40.
I also want to know how to create widget programmatically?
To set the font to white and the size to 40 change the paint as follows:
public void paint(Graphics graphics) {
int rectHeight = getPreferredHeight();
int rectWidth = getPreferredWidth();
Font font = Font.getDefault().derive(Font.BOLD, 40);
graphics.setColor(Color.WHITE);
graphics.setFont(font);
graphics.drawRect(0, 0, rectWidth, rectHeight);
graphics.drawText(_text, rectWidth / 2, 10);
super.paint(graphics);
}
I am working a UI based application in BlackBerry. UI is like the following:
label-1 : Oject choice field-1
label-2 : Oject choice field-2
label-3 : Oject choice field-3
label-4 : Oject choice field-4
label-5 : Oject choice field-5
It is really getting difficult to generate this UI. The width and height is the main issue for my difficulty.

I am fine with the width of the OCF but height and the position of the OCF must be settled as required. This is the output I am getting with this code.
This answer is based on following links:
Align Field in HorizontalFieldManager.
BlackBerry HorizontalFieldManager alignment.
Try following code:
class HomeScreen extends MainScreen {
public HomeScreen() {
super(Field.USE_ALL_WIDTH | Field.USE_ALL_HEIGHT | MainScreen.VERTICAL_SCROLL);
VerticalFieldManager vfmMain = new VerticalFieldManager(Field.USE_ALL_WIDTH);
// LabelField
LabelField lblFOne = new LabelField("LabelField One", Field.FIELD_LEFT | Field.FIELD_VCENTER);
// ObjectChoiceField
VerticalFieldManager vfmChoiceFieldContainerOne = new VerticalFieldManager(Field.USE_ALL_WIDTH | Field.FIELD_RIGHT);
final String[] options = new String[] { "Choice One - A very long string.", "Choice B", "Choice C" };
ObjectChoiceField ocfOne = new ObjectChoiceField("", options, 0, Field.FIELD_RIGHT | ObjectChoiceField.FORCE_SINGLE_LINE);
vfmChoiceFieldContainerOne.add(ocfOne);
// Contain a row of LabelField and ObjectChoiceField
HorizontalFieldManager hfmRowOne = new HorizontalFieldManager(Field.USE_ALL_WIDTH | Field.FOCUSABLE);
hfmRowOne.setBackground(BackgroundFactory.createSolidBackground(Color.GREEN));
hfmRowOne.add(lblFOne);
hfmRowOne.add(vfmChoiceFieldContainerOne);
vfmMain.add(hfmRowOne);
add(vfmMain);
}
}
I am developing an application where I should use nested horizontalmanagers. I am taking inner and outer HFMs. The fields of innerHFM overlap on the outerHFM when I scroll the fields. How can I use setExtent method for innerHFM. My innerHFM contains fields like 1 2 3 4 5 and my outerHFM contains next and previous buttons. Here is the code I implemented
outerHFM = new HorizontalFieldManager() {
protected void sublayout(int maxWidth, int maxHeight) {
layoutChild(next, maxWidth, maxHeight);
setPositionChild(next, 300, 5);
layoutChild(innerHfm, 200, maxHeight);
setPositionChild(innerHfm, 10, 5);
layoutChild(previous, maxWidth, maxHeight);
setPositionChild(previous, 44, 5);
setExtent(maxWidth, 40);
}
};
innerHfm = new HorizontalFieldManager(Manager.HORIZONTAL_SCROLL|Manager.USE_ALL_WIDTH) {
protected void sublayout(int maxWidth, int maxHeight) {
int space = 0;
int x = 90;
for (int i = 0; i < cardsSize; i++) {
layoutChild(numbtn[i], 210, maxHeight);
setPositionChild(numbtn[i], x + space+offset, 0);
space = space + 50;
}
setExtent(240, 40);
}
};
Hi this sizing works for all my field managers.
int managerWidth;
int managerHeight;
public int getPreferredWidth() {
return managerWidth;
}
public int getPreferredHeight() {
return managerHeight;
}
public void sublayout(int w, int h) {
super.sublayout(managerWidth, managerHeight);
setExtent(managerWidth, managerHeight);
}
maybe that manualy positionig might be problem, you can use AbsoluteFieldManager instead...
