J2ME Label Example

     

This is the simple create label example in which we create an StringItem to display the "UserId" as a label text. In the given application we are using setLabel to set the new label to the ItemString. We are replacing the new label on the place of previous label and setText on the position on the previous text. The complete source code is given below and the screenshot of the application given below for easy to understand. 

  • item.setLabel("E-MAIL ID: ");
  • item.setText("[email protected]"); 
  • form.removeCommand(next);

 

 

 

 

The Application is as follows:

 

 

LabelMIDlet.java

 

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class LabelMIDlet extends MIDlet implements CommandListener{
  private Display display; 
  private Form form; 
  private StringItem item; 
  private Command next, exit; 
  
  public LabelMIDlet(){
  display = Display.getDisplay(this);  
  form = new Form("Label Text")
  item = new StringItem("UserId: ""[email protected]");
  next = new Command("Next", Command.SCREEN, 1);
  exit = new Command("Exit", Command.EXIT, 1);
  form.addCommand(exit);
  form.addCommand(next);  
  form.append(item);
  form.setCommandListener(this)
  }

  public void startApp(){  
  display.setCurrent(form);
  }

  public void pauseApp(){ }

  public void destroyApp(boolean unconditional){
  notifyDestroyed();
  }

  public void commandAction(Command c, Displayable s){
  String label = c.getLabel();
  if (label.equals("Next")){
  item.setLabel("E-MAIL ID: ");
  item.setText("[email protected]")
  form.removeCommand(next);
  else if (label.equals("Exit")) {
  destroyApp(true);
  
  }
}
