最近有点乱糟糟,还是继续写完剩下的:
新建一个工程 calender:作为日历的完整工程开始实现一个日历小程序
创建类CalendarMain.java 作为日历的入口
创建日历布局外观类:CalenderLayout.java,作为主要的日历布局
CalendarMain类的应该如下结构:
<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->
package
org.bulktree.calender;
import
net.rim.device.api.ui.UiApplication;
import
net.rim.device.api.ui.container.MainScreen;
public
class
CalendarMain
extends
UiApplication {
public
static
void
main(String[] args) {
CalendarMain theApp
=
new
CalendarMain();
theApp.enterEventDispatcher();
}
public
CalendarMain() {
MainScreen mainScreen
=
new
MainScreen();
CalenderLayout calender
=
new
CalenderLayout();
mainScreen.add(calender.calLayout());
pushScreen(mainScreen);
}
}
黑莓程序入口总是先实现当前的屏幕
pushScreen(mainScreen)压入当前屏幕队列,然后维护主应用程序事件线程。
对于屏幕布局就很简单了:先画一个布局图
我用Excel模拟出一个日历,不同的颜色区域(当前日历红色除外),把整个日历作为分成三块,如果按照BlackBerry程序的方式,分为三个布局管理器,最上面是一个HorizontalFieldManager,日历的周那个区域也是HorizontalFieldManager,日期区域每行看成一个HorizontalFieldManager,整体看成一个VerticalFieldManager,而整个日历可看成一个VerticalFieldManager去规范里面的布局。这样一个完整的日历就出来了。具体实现如下:

这里面用到CalendarUtil工具类,ChineseCalendar农历工具类,CalenderField自定义的UI(上篇专门说明过)。现贴出代码如下:
