public class AndroidEAN13Activity extends Activity {
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        // ToDo add your GUI initialization code here
 
        this.setContentView(R.layout.main);
        TextView t = (TextView)findViewById(R.id.barcode);
 
        // set barcode font for TextView.
        // ttf file must be placed is assets/fonts 
        Typeface font = Typeface.createFromAsset(this.getAssets(), 
                        "fonts/EanP72Tt Normal.Ttf");
        t.setTypeface(font);
 
        // generate barcode string      
        EAN13CodeBuilder bb = new EAN13CodeBuilder("124958761310");
        t.setText(bb.getCode());
    }
}

je besoin de connaitre un exemple ou Tutorial pour générer un autre type de code barre comme code39,code128,code93.

Merci
