JavaFX实现简单日历效果

本文实例为大家分享了javafx实现简单日历效果的具体代码，供大家参考，具体内容如下

1.先看效果：

2.代码：

1）clockedge.java类

这个类（pane）主要是用来设置时钟边缘（为了美观对直了半天，其实想想也没必要~。~）

package com.javabasic.javafx; 
 
import javafx.scene.layout.pane;
import javafx.scene.paint.color;
import javafx.scene.shape.circle;
import javafx.scene.shape.line;
import javafx.scene.text.text; 
 
/**

 * 功能：显示时钟边缘 
 */ 
public class clockedge extends pane{ 
 private double w , h; 
 public clockedge(){ 
  this(200, 200); 
  paint(); 
 } 
 public clockedge(double w, double h){ 
  this.w = w; 
  this.h = h; 
  paint(); 
 } 
 public double getw() { 
  return w; 
 } 
 public void setw(double w) { 
  this.w = w; 
  paint(); 
 }

  text text9 = new text(centerx + clockradius * math.sin(9 * math.pi / 6) - 1.7 * (1 + math.cos(18 * math.pi / 6)) + 2.2 * math.sin(18 * math.pi / 6),

  text text10 = new text(centerx + clockradius * math.sin(10 * math.pi / 6) - 3.8 * (1 + math.cos(20 * math.pi / 6)) - 2.2 * math.sin(20 * math.pi / 6),

    line point = new line(pointx1, pointy1, pointx2, pointy2); 
    getchildren().add(point); 
   } 
  } 
 } 
  
} 

2)clockpointer.java类

这个类（pane）主要用来显示时钟的三个指针（时、分、秒）；

package com.javabasic.javafx; 
 
import java.util.calendar; 
import java.util.gregoriancalendar; 
import javafx.scene.layout.pane; 
import javafx.scene.paint.color; 
import javafx.scene.shape.line; 
/** 
 * @version 1.00 2016-10-15 
 * @author administrator 
 * 功能：显示时钟指针 
 */ 
public class clockpointer extends pane{ 
 private int hour; 
 private int minute; 
 private int second; 
 private double w = 200, h = 200; 
 public clockpointer(){ 
  setcurrenttime(); 
 } 
 public clockpointer(int hour, int minute, int second){ 
  this.hour = hour; 
  this.minute = minute; 
  this.second = second; 
  paint();  
 } 
 public int gethour(){ 
  return hour; 
 } 
 public void sethour(int hour){ 
  this.hour = hour; 
  paint(); 
 } 
 public int getminute(){ 
  return minute; 
 } 
 public void setminute(int minute){ 
  this.minute = minute; 
  paint(); 
 } 
 public int getsecond(){ 
  return second; 
 } 
 public void setsecond(int second){ 
  this.second = second; 
  paint(); 
 } 
 public double getw() { 
  return w; 
 } 
 public void setw(double w) { 
  this.w = w; 
  paint(); 
 } 
 public double geth() { 
  return h; 
 } 
 public void seth(double h) { 
  this.h = h; 
  paint(); 
 } 
 public string setcurrenttime(){ 
  string str1, str2, str3;
  calendar calendar = new gregoriancalendar(); 
  this.hour = calendar.get(calendar.hour_of_day); 
  this.minute = calendar.get(calendar.minute); 
  this.second = calendar.get(calendar.second);
  str1 = string.valueof(hour);
  str2 = string.valueof(minute);
  str3 = string.valueof(second);
 if (hour < 10) {
 str1 = "0" + hour;
 }
 if (minute < 10) {
 str2 = "0" + minute;
 }
 if (second < 10) {
 str3 = "0" + second;
 }
  paint();
  return str1 + " : " + str2 + " : " + str3; 
 } 
 protected void paint(){ 
  getchildren().clear(); 
  double clockradius = math.min(w, h) * 0.8 * 0.5; 
  double centerx = w / 2; 
  double centery = h / 2; 
  double slength = clockradius * 0.8; 
  double secondx = centerx + slength * math.sin(second * (2 * math.pi) / 60); 
  double secondy = centery - slength * math.cos(second * (2 * math.pi) / 60); 
  line sline = new line(centerx, centery, secondx, secondy); 
  sline.setstroke(color.red); 
  double mlength = clockradius * 0.65; 
  double minutex = centerx + mlength * math.sin(minute * (2 * math.pi) / 60); 
  double minutey = centery - mlength * math.cos(minute * (2 * math.pi) / 60); 
  line mline = new line(centerx, centery, minutex, minutey); 
  mline.setstroke(color.blue); 
  double hlength = clockradius * 0.5; 
  double hourx = centerx + hlength * math.sin(hour * (2 * math.pi) / 12); 
  double houry = centery - hlength * math.cos(hour * (2 * math.pi) / 12); 
  line hline = new line(centerx, centery, hourx, houry); 
  mline.setstroke(color.green); 
  getchildren().addall(sline, mline, hline); 
 } 
} 

3)calendarpanel.java类

这个类（pane）用来显示日历（这里用到了一个字体cooper black一般系统应该都有，没有就得添加）

package com.javabasic.javafx; 
 
import javafx.scene.layout.pane; 
import javafx.scene.layout.columnconstraints; 
import javafx.scene.layout.gridpane; 
import javafx.scene.control.label; 
import javafx.scene.paint.color; 
import javafx.geometry.hpos; 
import javafx.geometry.insets; 
import javafx.geometry.pos; 
import javafx.scene.text.font; 
import javafx.scene.text.fontweight; 
import javafx.scene.text.text; 
import java.util.calendar; 
/** 
 * @version 1.00 2016-10-17 
 * @author administrator 
 * 功能：显示日历 
 */ 
 
public class calendarpanel extends pane{ 
 private int year; 
 private int month; 
 private int day; 
 private int firstdayofweek; 
 private int totaldayofmonth; 
  
 public calendarpanel(){ 
   
  calendar calendar = calendar.getinstance(); 
  year = calendar.get(calendar.year); 
  month = calendar.get(calendar.month) + 1; 
  day = calendar.get(calendar.day_of_month); 
  totaldayofmonth = calendar.getactualmaximum(calendar.date); 
  calendar.set(calendar.day_of_month, 1); 
  firstdayofweek = calendar.get(calendar.day_of_week) - 1; 
  paint(); 
 } 
 public void paint(){ 
  gridpane cp = new gridpane(); 
  string[] week = new string[]{"sun", "mon", "tue", "wed", "thu", "fri", "sat"}; 
  cp.setpadding(new insets(30, 30, 10, 10)); 
  text text1 = new text(year + "年" + month + "月"); 
  text1.setstroke(color.green); 
  cp.setalignment(pos.center); 
  cp.add(text1, 0, 0); 
  gridpane.setcolumnspan(text1, 7); 
  gridpane.sethalignment(text1, hpos.center); 
  for(int i = 0; i < 7; i++){ 
   label label = new label(week[i]); 
   if(i == 0 || i == 6) label.settextfill(color.red); 
   cp.add(label, i, 1); 
   cp.getcolumnconstraints().add(new columnconstraints(30)); 
   gridpane.sethalignment(label, hpos.center); 
  } 
  for(int j = 0; j < totaldayofmonth; j++){ 
   label label = new label(j + 1 +""); 
   if (j + 1 == day) label.setfont(font.font("cooper black", fontweight.bold, 20)); 
   int k = firstdayofweek + j; 
   if((k % 7 == 0) || (k % 7 == 6)) label.settextfill(color.red); 
   cp.add(label, k % 7, 2 + k / 7); 
   gridpane.sethalignment(label, hpos.right); 
  } 
  getchildren().add(cp); 
 } 
 
}

4)主面板clockmainpanel.java

这个类（pane）是用于将上面三个面板合成主面板

package com.javabasic.javafx; 
 
import javafx.animation.keyframe;
import javafx.animation.timeline;
import javafx.application.application;
import javafx.event.actionevent;
import javafx.event.eventhandler;
import javafx.scene.scene;
import javafx.scene.layout.borderpane;
import javafx.scene.layout.stackpane;
import javafx.scene.text.font;
import javafx.scene.text.text;
import javafx.stage.stage;
import javafx.util.duration; 
/** 
 * @version 1.00 2016-10-17 
 * @author administrator 
 * 功能：各个面板pane合成一个时钟面板clockmainpanel 
 */ 
public class clockmainpanel extends application { 
 string nowtime; 
 public static void main(string[] args) { 
  // todo auto-generated method stub 
  application.launch(args); 
 } 
 public void start(stage primarystage){ 
  clockedge ce = new clockedge(); 
  clockpointer cp = new clockpointer(); 
  stackpane sp = new stackpane(ce, cp); 
  stackpane nt = new stackpane(); 
  calendarpanel capa = new calendarpanel(); 
  borderpane bp = new borderpane(); 
  bp.setleft(sp); 
  bp.setright(capa); 
  bp.setbottom(nt); 
  scene scene = new scene(bp, 420, 200); 
  eventhandler<actionevent> eventhandler = e ->{ 
   nt.getchildren().clear(); 
   nowtime = (string) cp.setcurrenttime(); 
   text tt= new text(nowtime);
   tt.setfont(font.font("times new roman", 20));
   nt.getchildren().add(tt); 
  }; 
  timeline animation = new timeline( 
   new keyframe(duration.millis(1000), eventhandler)); 
  animation.setcyclecount(timeline.indefinite); 
  animation.play(); 
  primarystage.settitle("perpetual calendar"); 
  primarystage.setscene(scene); 
  primarystage.show(); 
 } 
}
