代理一个日历项目问题

Question

我正在处理我的Codename一个日历项目，其中我包含了Calendar而不是Codename one API，但是自己创建了一个自定义日历因此，当我使用for循环向日历添加日期按钮时，它将成功添加，但是它将从星期日开始的第一天开始，但是实际的日历月不是从星期日开始的，所以如何从那个受人尊敬的实际日期添加它，而且我希望当下个月开始日期按钮将继续例如，从上个月到下个月的相应链，如果当前月份在周三结束，那么下个月的第一天将从星期四开始，依此类推。所以任何人都知道如何实现这种情况？

以下是我的应用程序屏幕截图及其尊重的代码：

public class PivDisplayCalendar extends Container {
    PivEventCalendar EventObject = new PivEventCalendar();
    PivCalendarModel ModelObject = new PivCalendarModel();
    PivCalendarDatabase DatabaseObject = new PivCalendarDatabase();
    int length =31;
     private ComboBox year;
     private static final String[] DAYS = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
     private static final String[] LABELS = {"Su", "M", "Tu", "W", "Th", "F", "Sa"};
     private static final String[] MONTHS = {"January","February","March","April","May","June","July","August","September","October","November","December"};
     private static final int[] YEARS = {2017,2018,2019,2020,2021,2022,2023,2024,2025,2026,2027};
     public int i = 1, j=0;
     public Date value = new Date();
     public Object metaData;

     private ArrayList<Button> allButtons = new ArrayList<Button>();
     //Button newButton = new Button("");

    public PivDisplayCalendar(){
        super(new BoxLayout(BoxLayout.Y_AXIS));
            Log.p("Calendar invoked");
            Container calendarTitle = new Container(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER));
            Container title = new Container(new GridLayout(1,7));
            Container days = new Container(new GridLayout(6, 7));
            Container calendarTitleCopy = new Container(new GridLayout(1, 1));
                calendarTitleCopy.setUIID("CalendarTitleCopy");
            this.addComponent(calendarTitleCopy);
            this.addComponent(title);
            this.addComponent(days);


            Button prevMonth = new Button("<");

            }
            for (int iter = 0; iter < DAYS.length; iter++) {
