Hi all,
i am trying to develop a program where in a picture scroller appears at the bottom of the mobile screen, but am not able to figure out layout managers, the screen appears just plain white. Please help,
Here is the code below for screen
public class MobiletvMainScreen extends MainScreen {
VerticalFieldManager Vfm;
//HorizontalFieldManager Hfm;
FieldManager fm = new FieldManager();
//Determine half of the screen Height.
//int Sheight = Graphics.getScreenHeight() / 3;
//int Swidth = Graphics.getScreenWidth();
MobiletvMainScreen() {
Vfm = new VerticalFieldManager(USE_ALL_WIDTH);
//Hfm = new HorizontalFieldManager(FIELD_BOTTOM);
Bitmap images[] = new Bitmap[9];
String[] labels = new String[9];
String[] tooltips = new String[9];
ScrollEntry[] entries= new ScrollEntry[9];
for (int i = 0; i < entries.length; i++)
{
imgIndex = i+1;
images[i] = Bitmap.getBitmapResource("resource/pic" + imgIndex+ ".png");
labels [i] = "Label for image" + imgIndex;
tooltips[i] = "Tooltips for image" +imgIndex;
entries[i] = new ScrollEntry(images[i], labels[i], tooltips[i]);
}
PictureScroll pictureScroll = new PictureScroll(entries);
fm.add(pictureScroll);
Vfm.add(fm);
add(Vfm);
}
private class PictureScroll extends PictureScrollField {
private final ScrollEntry[] _entries;
PictureScroll(ScrollEntry[] entries) {
super(200,327);
_entries = entries;
this.setImageDistance(50);
this.setData(entries, 0);
this.setHighlightStyle(HighlightStyle.ILLUMINATE_WITH_MAGNIFY_LENS);
this.setHighlightBorderColor(Color.BLUE);
}
}
}
Here is the Fieldmanager Class
public class FieldManager extends Manager{
FieldManager() {
super(FIELD_BOTTOM);
}
//int Swidth = Graphics.getScreenWidth();
//int Sheight = Graphics.getScreenHeight()/3;
protected void sublayout(int width, int height) {
//if (getFieldCount() > 0) {
Field centeredField = getField(0);
layoutChild(centeredField, getPreferredwidth(), getPreferredheight());
setPositionChild(centeredField,getPreferredwidth(), getPreferredheight() );
setExtent(Graphics.getScreenWidth(), Graphics.getScreenHeight()/2);
}
