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);
    
  }
}
