Re: Update the screen

Hi,

  Please look into the API, there is a close method available for Screen class. you can use this to close the currnet Screen. When it comes to display the values on BasicEditField, please look for BasicEditField class it has a methods like setText, insert and getText which will server your requirement.

 

Thank you.

Re: Update the screen

pass your first screen object (dirty) or a similar interface (cleaner) to your second screen and implement a public method that you can call from your second screen.

for example (without interface):
//in screen1
public void update(String text){
basicEditField.setText(text);
}
pushScreen(new Screen2(screen1));
// in screen2
screen1.update("newtext");

read about callbacks, google features plenty articles.
