Immutable Image MIDlet Example

This is the immutable image example, which shows how to create a immutable image in MIDlet. In this example we are creating a image without using of canvas. Following methods are used in the source code:

Image image = Image.createImage("/mobile.png");
Image image1 = Image.createImage("/phone.png");
form.append(new ImageItem(null, image, ImageItem.LAYOUT_NEWLINE_BEFORE | ImageItem.LAYOUT_CENTER | ImageItem.LAYOUT_NEWLINE_AFTER, null));
form.append(new ImageItem(null, image1, ImageItem.LAYOUT_NEWLINE_BEFORE | ImageItem.LAYOUT_CENTER | ImageItem.LAYOUT_NEWLINE_AFTER, null));

The Application is as follows:

Source Code of ImutableImage.java


import javax.microedition.midlet.*;

import javax.microedition.lcdui.*;



public class ImutableImage extends MIDlet  implements CommandListener{

  private Display display;  

  private Form form; 

  private Command exit;



  public void startApp() {

    display = Display.getDisplay(this);

    exit = new Command("Exit", Command.EXIT, 1);

    form = new Form("");    

    form.addCommand(exit);

    form.setCommandListener(this);   

    try { 

      Image image = Image.createImage("/mobile.png");

      Image image1 = Image.createImage("/phone.png");

      form.append(new ImageItem(null, image, ImageItem.LAYOUT_NEWLINE_BEFORE 

        | ImageItem.LAYOUT_CENTER | ImageItem.LAYOUT_NEWLINE_AFTER, null));

      form.append(new ImageItem(null, image1, ImageItem.LAYOUT_NEWLINE_BEFORE 

       | ImageItem.LAYOUT_CENTER | ImageItem.LAYOUT_NEWLINE_AFTER, null));      

      display.setCurrent(form);

    }catch (java.io.IOException e){

      System.err.println(e);

    }

    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("Exit")){

      destroyApp(false);

    } 

  }

}
