List with images

You can add images to a list by specifying the image parameter of the append(Element, Image) of the list.

listObj.append("Item1",imageObject);

The imageObject can be created by using the createImage(Image_path) of the Image class.

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

Example:

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

public class ListImage extends MIDlet implements CommandListener{
private Display display;
private Form form;
private TextField txtname,txtpassword;
private Command Cmdok, Cmdcancel,ba,select;
private List lst;

public ListImage() {
display = Display.getDisplay(this);

}

public void startApp() {
form=new Form("Login");
txtname=new TextField("User id:","",250,TextField.ANY);
txtpassword=new TextField("Password:","",250,TextField.PASSWORD);
Cmdok=new Command("Ok",Command.OK, 0);
Cmdcancel=new Command("Cancel",Command.CANCEL,0);

form.append(txtname);
form.append(txtpassword);
form.addCommand(Cmdok);
form.addCommand(Cmdcancel);
form.setCommandListener(this);
display.setCurrent(form);

}

public void pauseApp() {}

public void destroyApp(boolean unconditional) {}

public void commandAction(Command c, Displayable s) {
if(c==Cmdcancel) notifyDestroyed();
else if(c==Cmdok) check();
else if(c==ba) display.setCurrent(form);
else if(c==select) showselecteditem();
}

public void check(){
if(txtname.getString().equals("dara") && txtpassword.getString().equals("123")){
showlist();
}
else{
Alert al=new Alert("Incorrect","Invalid login!",null, AlertType.ERROR);
display.setCurrent(al);
}
}

public void showlist(){
ba=new Command("Back",Command.BACK,0);
select=new Command("Select",Command.OK,0);
lst=new List("Select the item:",List.EXCLUSIVE);
Image m=null;
try{m=Image.createImage("/imglist.png");}catch(Exception e){}
lst.append("Item 1",m);
lst.append("Item 2",m);
lst.append("Item 3",m);
lst.append("Item 4",m);
lst.append("Item 5",m);
lst.addCommand(ba);
lst.addCommand(select);
lst.setCommandListener(this);
display.setCurrent(lst);
}

public void showselecteditem(){
String selectedvalue=lst.getString(lst.getSelectedIndex());
System.out.println(selectedvalue);
}
