LWUIT日历日期格式

Question

如何在转换为“YYYY-Mon-DD”后为今天日期添加一天。

注意到一些类在J2ME中不能工作，比如Simpledateformat类。

import javax.microedition.midlet.*;
import com.sun.lwuit.*;
import com.sun.lwuit.events.*;  
public class myLibrary extends MIDlet {

    Form f;    
    com.sun.lwuit.Calendar cal;
    Button b;      

    public void startApp()  {
        com.sun.lwuit.Display.init(this); 
        f = new com.sun.lwuit.Form();
        cal = new com.sun.lwuit.Calendar();
        b = new Button("Enter");
        f.addComponent(cal);
        f.addComponent(b);
        b.addActionListener( new ActionListener()   {
            public void actionPerformed(ActionEvent acv)    {
                System.out.println(""+cal.getDate());
            } 
        });

        f.show();
    }
    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
    }
}

为了使用java.lwuit.Calendar类，要以这种格式获取日期，需要从cal.getdate()中子串数据。

例如

System.out.println("DAY " + cal.getDate().toString().substring(0,3));

这样做，您将获得数据，然后在字符串中重新排序。

java.util.Calendar c = Calendar.getInstnace();
c.set(Calendar.DAY_OF_THE_MONTH, day_that_you want);
c.set(Calendar.MONTH, month_that_you want);
c.set(Calendar.YEAR, year_that_you want);

java.lwuit.Calendar cal = new java.lwuit.Calendar();
cal.setDate(c.getDate().getTime());

private static final int DAY = 24 * 60 * 60 * 1000; 
Date d = new Date(); d.setTime(d.getTime() + DAY);
