I am working on a simple J2ME application and i have a StringItem linked to a terms and conditions page online.
I have the StringItem setup and it appears underlined (giving the feeling that it is linked); but when i click on it, it does not perform any action.
Find below my code:
public class mobiMidlet extends MIDlet implements CommandListener {
private Display display;
private TextField userName,password;
public Form form;
private Command login, register, forgot, terms, cancel;
private Image img_error, img_login, img_register, img_forgot, img_terms;
private String termsurl = "http://example.com/terms.php";
private StringItem termsItem;
public mobiMidlet() {
form = new Form("Welcome to My App");
termsItem = new StringItem("", "Terms and Conditions", Item.HYPERLINK);
termsItem.setDefaultCommand(new Command("terms", Command.ITEM, 1));
ItemCommandListener listener = new ItemCommandListener() {
public void commandAction(Command cmd, Item item) {
if(cmd==terms)
{
try {
platformRequest(termsurl);
} catch (Exception e) {
e.printStackTrace();
}
}
}
};
termsItem.setItemCommandListener(listener);
userName = new TextField("LoginID:", "", 30, TextField.ANY);
password = new TextField("Password:", "", 30, TextField.PASSWORD);
cancel = new Command("Cancel", Command.CANCEL, 2);
login = new Command("Login", Command.OK, 2);
try{
img_login = Image.createImage("/logo.jpg");
img_register = Image.createImage("/error2.png");
img_forgot = Image.createImage("/logo.jpg");
img_register = Image.createImage("/error2.png");
}catch(Exception e){
System.out.println(e.getMessage());
}
}
public void startApp() {
display = Display.getDisplay(this);
form.append(termsItem);
form.append(userName);
form.append(password);
form.addCommand(cancel);
form.addCommand(login);
form.setCommandListener(this);
display.setCurrent(form);
}
public void commandAction(Command c, Displayable d) {
String label = c.getLabel();
if(label.equals("Cancel")) {
destroyApp(true);
} else if(label.equals("Login")) {
validateUser(userName.getString(), password.getString());
}
}
}
How can I fix this so that when I click on the terms and conditions link, it opens the page on a browser?
You have not initialized variable terms
, so it remains null
. Therefore condition cmd==terms
is always false
and you never enter the if
statement.
Separate line termsItem.setDefaultCommand(new Command("terms", Command.ITEM, 1));
to two:
terms = new Command("terms", Command.ITEM, 1);
termsItem.setDefaultCommand(terms);
Now you have a chance.
BTW why not to debug you program? Run it in emulator, put break point into commandAction
and see what happens.
