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("");    
      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, 
      form.append(new ImageItem(null, image1, ImageItem.LAYOUT_NEWLINE_BEFORE 
    }catch (java.io.IOException e){

  public void pauseApp(){}

  public void destroyApp(boolean unconditional){

  public void commandAction(Command c, Displayable s){
    String label = c.getLabel();
    if (label.equals("Exit")){
