membuat Button dari StringItem di J2ME

hmmm ada pertanyaan lagi pas mo ngerjain TA
gmn ya bikin button pada form di Midlet

cari2 di example ternyata ketemu,lagi2 sederhana heheh ga sesusah yang dibayangkan karena API Midp 2.0 udah lumayan lenkap
sama kek ItemStateListener yg pernh aq tulis dulu
lagi2 di J2ME kebanyakan pake Interface
nah tryt ada interface untuk item command listener ItemCommandListener

nah drpd disimpen ndiri skr aq tulis deh disini
biasa langkah2 dulu hehehe
1. implemen dulu interface ItemCommandListener ke midlet

public class StringButton extends MIDlet implements ItemCommandListener {
}

2. pilih tipe StringItem menjadi BUTTON dan set default commandnya

item = new StringItem(“Button “, “Button”, Item.BUTTON);
item.setDefaultCommand(CMD_OK);
item.setItemCommandListener(this);

3, dafultmethodnya harus ada

public void commandAction(Command c, Item item) {
(c == CMD_OK) {
String text = “tombol ok ditekan”;
Alert alert = new Alert(“Action”, text, null, AlertType.INFO);
display.setCurrent(alert);
}
}

contoh simple skrip lengkapnya dibawah ini


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

public class StringButton extends MIDlet implements ItemCommandListener {
private static final Command CMD_OK = new Command("Go", Command.ITEM, 1);
private Display display;
private Form mainForm;

protected void startApp() {
display = Display.getDisplay(this);

mainForm = new Form("Button Demo");

item = new StringItem("Button ", "Button", Item.BUTTON);
item.setDefaultCommand(CMD_OK);
item.setItemCommandListener(this);
display.setCurrent(mainForm);
}

public void commandAction(Command c, Item item) {
if (c == CMD_OK) {
String text = "tekan tombol nie";
Alert a = new Alert("Action", text, null, AlertType.INFO);
display.setCurrent(a);
}
}

public void commandAction(Command c, Displayable d) {
destroyApp(false);
notifyDestroyed();
}

protected void destroyApp(boolean unconditional) {
}

protected void pauseApp() {
}
}


oke guys slamat mencoba
smoga anda smakin suka dengan J2ME hehehe

tunggu tulisan2 J2ME berikutx ya ntr mo bahas J2ME POLISH
apaan tu?tgg ye…

Item Listener in J2ME

dalam programming pasti dikenal istilah even handler atau listener kalau di JAVA, even adalah kapan program disuru melakukan sesuatu atas perintah user,misalnya
onClick,button click,onChange n byk banget yang lainya yg tidak bisa aq sebutin 1 per 1 hehehe

nah kalo di desktop atau web application pastinya aq da terbiasa banget menggunakanx waktu develope suatu aplikasi
nah pertanyaanx gmn klo even atau listener pada mobile app dengan J2ME???
aq mulai cari2 ttg ini krn brhubungan dengan TA ku yaitu Mobile Commerce with J2ME
stlh googling akirx ketemu dah carax

simple n mudah ternyata
klo uda biasa coding pake Java pastix da tw donk Interface
nah tryt di J2ME da Interface yg namax ItemStateListener

1. langkah2 menggunakan ItemStateListener sebelumx qt mesti implement interface tersebut ke class Midlet qt seperti dibawah ini

public final class ContohListener extends MIDlet implements ItemStateListener

2. nah setelah qt lakukan diatas set ItemStateListener pada display

setItemStateListener (this);

3. default method harus ada dan method yg digunakan adalah
public void itemStateChanged(Item item) throws

UnsupportedFieldException {
if(item==e_gender) {
int index = e_gender.getSelectedIndex ();
System.out.println(“Error” + index);
switch (index) {
case 0:
System.out.println(“Male”);
break;
case 1:
System.out.println(“Female”);
break;
}
}
}

dan dibawah ini contoh code yang barusan aq bwt
