Codenameone-日历createDay()导航

Command edit = new Command("", im) {
@Override
public void actionPerformed(ActionEvent evt) {
System.out.println("Editing");
}
};
home.getToolbar().addCommandToRightBar(edit);
home.show();
}
protected void setBackCommand(Form f) {
Command back = new Command("") {

public void actionPerformed(ActionEvent evt) {
home.showBack();
}
};
Image img = FontImage.createMaterial(FontImage.MATERIAL_ARROW_BACK, UIManager.getInstance().getComponentStyle("TitleCommand"));
back.setIcon(img);
f.getToolbar().addCommandToLeftBar(back);
f.getToolbar().setTitleCentered(true);
f.setBackCommand(back);
}
public void stop() {
current = getCurrentForm();
}
public void destroy() {
}}
我已经相应地重写了Calendar类
public class mainCalendar extends Calendar { @Override
protected Button createDay(){ Button day = new Button();
Image im = FontImage.createMaterial(FontImage.MATERIAL_MODE_EDIT, UIManager.getInstance().getComponentStyle("Command"));
day.setIcon(im);
return day;
}
@Override
protected void updateButtonDayDate(Button dayButton, int currentMonth, int day) {
//Customize day values
dayButton.setText("" +day);
}}
主窗体设法进入窗体1和窗体2(侧菜单)。我知道表单3确实存在,但不确定为什么无法从createDay()访问表单3。我怀疑这段代码在主窗体中的某个地方出错了
Calendar.createDay().pressed();
Calendar.createDay().released();
Calendar.createDay().setCommand(cmd3);
需要建议和/或帮助。查看创建自定义日历日组件的。您不需要以下代码:
Calendar.createDay().pressed();
Calendar.createDay().released();
Calendar.createDay().setCommand(cmd3);
日历日的按下和释放通过actionListener
处理,如果使用自定义日组件,则可以通过覆盖bindDayListener()
来实现;如果使用默认日按钮,则可以通过覆盖addDayActionListener()
来实现。例如:
Calendar.addDayActionListener(evt -> {
//show your next form here
});
除非您需要高级定制,否则我认为没有必要将Calendar类子类化。您的问题是什么?谢谢。我再试试你的建议。代码是有效的。我的代码有错误&也是因为我没有相应地更新CN1库。愚蠢的我…@buzzin_hornets很高兴它起作用了…请给出答案顺便说一句,正确的Java编码标准是从变量名开始使用小写字母,从类名开始使用大写字母,从方法/函数名开始使用小写字母
mainCalendar
类应变为mainCalendar
,Calendar
变量应为Calendar
或cal
。常量应全部大写
