///////////////////////////////// ScreenB 2nd Screeeeeeeeeeeeeeeeeennnnnnnnnn//////////////


public class ScreenB extends MainScreen
{

public ScreenB()
{
LabelField title = new LabelField("ScreenB", LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
setTitle(title);
EditField dig = new EditField("Please enter Your Name ", "", 32, EditField.FILTER_DEFAULT);
add(dig);
ButtonField btnS = new ButtonField("Next", ButtonField.FIELD_LEFT|ButtonField.CONSUME_CLICK);
add(btnS);
btnS.setChangeListener(new ButtonListener());
}

public class ButtonListener implements FieldChangeListener
{
public void fieldChanged(Field field, int context)
{
ButtonField btn = (ButtonField)field;
try
{
Name = dig.toString();
if (btn.getLabel() == "Next")
SendMessage(); /// Sending message on this action
}
catch (Exception e)
{
Dialog.alert("Error: "+e);
}
}
}
public void close()
{
// pushScreen(new ScreenA());

ScreenA sc = (ScreenA) UiApplication.getUiApplication().getActiveScreen() .getScreenBelow();
sc.Refresh();
UiApplication.getUiApplication().popScreen(this);
}
}

Please assist whether this code is correct or not.

Here when I m calling sc.Refresh(); from close() of ScreenB

Its get in to the condition if (Name != null) on ScreenA and print
System.out.println("@454545454....."+titlee.toStri ng());

but while updating to Screen add(titlee);
Its showing : WARNING: Cannot layout field, insufficient height


Please Assist.... First Please check the code Is it correct or not.

I want to update Name Enter in Screen B to previous ScreenA which is in the Stack.

Please give example How to do this ...... I just got stuck in this!!!!!!!!!!!!!!!!!!!!!

If I use pushScreen(); then it will works fine..............But! again Memory and Stack Issue.


Please waiting for Replies....
