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; 

/**

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();
 }
 public double getH() {
  return h;
 }
 public void setH(double h) {
  this.h = h;
  paint();
 }
 public void paint(){
  double clockRadius = Math.min(w, h) * 0.8 * 0.5;
  double centerX = w / 2;
  double centerY = h / 2;
  Circle circle = new Circle(centerX, centerY, clockRadius);
  circle.setFill(Color.WHITE);
  circle.setStroke(Color.BLACK);
  //假设一个字符宽7.6个像素，高8.8个像素
  Text text1 = new Text(centerX + clockRadius * Math.sin(1 * Math.PI / 6) - 7.6 + 1.7 * (1 + Math.cos(2 * Math.PI / 6)) - 2.2 * Math.sin(2 * Math.PI / 6),

   else{
    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();
 }
}
