Звучит так, как будто вы захотите начать писать свои собственные классы поля, вот пример для начала:
import net.rim.device.api.system.Bitmap;
import net.rim.device.api.system.Display;
import net.rim.device.api.ui.Field;
import net.rim.device.api.ui.Graphics;
public class SimpleField extends Field {
private String label;
private Bitmap image;
private int fieldWidth;
private int fieldHeight;
private boolean hover = false;
private int focusColor = 0xcccccc;
public SimpleField(String label, Bitmap image) {
super(Field.FOCUSABLE);
this.label = label;
this.image = image;
fieldWidth = Display.getWidth();
fieldHeight = image.getHeight();
}
protected void onFocus(int direction) {
hover = true;
invalidate();
super.onFocus(direction);
}
protected void onUnfocus() {
hover = false;
invalidate();
super.onUnfocus();
}
public int getPreferredWidth() {
return fieldWidth;
}
public int getPreferredHeight() {
return fieldHeight;
}
protected void layout(int width, int height) {
setExtent(fieldWidth, fieldHeight);
}
protected void paint(Graphics graphics) {
if(hover){
graphics.setColor(focusColor);
graphics.fillRect(0, 0, fieldWidth, fieldHeight);
}
graphics.drawText(label, 0, (fieldHeight - graphics.getFont().getHeight()) / 2);
graphics.drawBitmap(graphics.getFont().getAdvance(label), 0, image.getWidth(), image.getHeight(), image, 0, 0);
}
}
