Answer 2

Here I create object of type PopupScreen and call the method givePopup:
PopupScreen popup1=givePopup();
PopupScreen givePopup(){
VerticalFieldManager popvfm =new VerticalFieldManager();
ButtonField ok=new ButtonField("ok");
ButtonField cancel=new ButtonField("cancel");
popvfm.add(ok);
popvfm.add(cancel);
PopupScreen popup=new PopupScreen(popvfm);
return popup;
}
This method returns a PopupScreen instance that has one vertical field manager and I add two button field on this manager.

public class FriendPopupScreen extends MainScreen{
int dialogWidth;
int dialogHeight;
LabelField lblTitle;
HorizontalFieldManager hfmTitle;
Vector data;
public FriendPopupScreen() {
dialogWidth = 300;
dialogHeight = 150;
lblTitle = newLabelField("Choose option");
hfmTitle = new HorizontalFieldManager(USE_ALL_WIDTH){
protected void sublayout(int maxWidth, int maxHeight) {
// TODO Auto-generated method stub
maxWidth= Display.getWidth();
maxHeight=40;
super.sublayout(maxWidth, maxHeight);
setExtent(maxWidth, maxHeight);
}
protected void paint(Graphics graphics) {
// TODO Auto-generated method stub
graphics.setBackgroundColor(Color.BLACK);
graphics.clear();
super.paint(graphics);
}
};
hfmTitle.add(lblTitle);
lblTitle.setMargin(10,0,0,10);
add(hfmTitle);
}
protected void sublayout( int width, int height ) {
setExtent( dialogWidth, dialogHeight );
setPosition( Display.getWidth()/2-(dialogWidth/2), Display.getHeight()/2 - (dialogHeight/2));
layoutDelegate( dialogWidth, dialogHeight );
}
}
and call this:
FriendPopupScreen popup = new FriendPopupScreen();
UiApplication.getUiApplication().pushModalScreen(popup);
