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; /** * @version 1.00 2016-10-15 * @author Administrator * 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(); } 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), centerY - clockRadius * Math.cos(1 * Math.PI / 6) + 8.8 + 1.7 * Math.sin(2 * Math.PI / 6) - 2.2 * (1 - Math.cos(2 * Math.PI / 6)), "1"); Text text2 = new Text(centerX + clockRadius * Math.sin(2 * Math.PI / 6) - 7.6 + 1.7 * (1 + Math.cos(4 * Math.PI / 6)) - 2.2 * Math.sin(4 * Math.PI / 6), centerY - clockRadius * Math.cos(2 * Math.PI / 6) + 8.8 + 1.7 * Math.sin(4 * Math.PI / 6) - 2.2 * (1 - Math.cos(4 * Math.PI / 6)), "2"); Text text3 = new Text(centerX + clockRadius * Math.sin(3 * Math.PI / 6) - 7.6 + 1.7 * (1 + Math.cos(6 * Math.PI / 6)) - 2.2 * Math.sin(6 * Math.PI / 6), centerY - clockRadius * Math.cos(3 * Math.PI / 6) + 8.8 + 1.7 * Math.sin(6 * Math.PI / 6) - 2.2 * (1 - Math.cos(6 * Math.PI / 6)), "3"); Text text4 = new Text(centerX + clockRadius * Math.sin(4 * Math.PI / 6) - 7.6 + 1.7 * (1 + Math.cos(8 * Math.PI / 6)) + 2.2 * Math.sin(8 * Math.PI / 6), centerY - clockRadius * Math.cos(4 * Math.PI / 6) + 1.7 * Math.sin(8 * Math.PI / 6) + 2.2 * (1 - Math.cos(8 * Math.PI / 6)), "4"); Text text5 = new Text(centerX + clockRadius * Math.sin(5 * Math.PI / 6) - 7.6 + 1.7 * (1 + Math.cos(10 * Math.PI / 6)) + 2.2 * Math.sin(10 * Math.PI / 6), centerY - clockRadius * Math.cos(5 * Math.PI / 6) + 1.7 * Math.sin(10 * Math.PI / 6) + 2.2 * (1 - Math.cos(10 * Math.PI / 6)), "5"); Text text6 = new Text(centerX + clockRadius * Math.sin(6 * Math.PI / 6) - 7.6 + 1.7 * (1 + Math.cos(12 * Math.PI / 6)) + 2.2 * Math.sin(12 * Math.PI / 6), centerY - clockRadius * Math.cos(6 * Math.PI / 6) + 1.7 * Math.sin(12 * Math.PI / 6) + 2.2 * (1 - Math.cos(12 * Math.PI / 6)), "6"); Text text7 = new Text(centerX + clockRadius * Math.sin(7 * Math.PI / 6) - 1.7 * (1 + Math.cos(14 * Math.PI / 6)) + 2.2 * Math.sin(14 * Math.PI / 6), centerY - clockRadius * Math.cos(7 * Math.PI / 6) - 1.7 * Math.sin(14 * Math.PI / 6) + 2.2 * (1 - Math.cos(14 * Math.PI / 6)), "7"); Text text8 = new Text(centerX + clockRadius * Math.sin(8 * Math.PI / 6) - 1.7 * (1 + Math.cos(16 * Math.PI / 6)) + 2.2 * Math.sin(16 * Math.PI / 6), centerY - clockRadius * Math.cos(8 * Math.PI / 6) - 1.7 * Math.sin(16 * Math.PI / 6) + 2.2 * (1 - Math.cos(16 * Math.PI / 6)), "8"); 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), centerY - clockRadius * Math.cos(9 * Math.PI / 6) - 1.7 * Math.sin(18 * Math.PI / 6) + 2.2 * (1 - Math.cos(18 * Math.PI / 6)), "9"); 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), centerY - clockRadius * Math.cos(10 * Math.PI / 6) + 8.8 - 3.8 * Math.sin(20 * Math.PI / 6) - 2.2 * (1 - Math.cos(20 * Math.PI / 6)), "10"); Text text11 = new Text(centerX + clockRadius * Math.sin(11 * Math.PI / 6) - 3.8 * (1 + Math.cos(22 * Math.PI / 6)) - 2.2 * Math.sin(22 * Math.PI / 6), centerY - clockRadius * Math.cos(11 * Math.PI / 6) + 8.8 - 3.8 * Math.sin(22 * Math.PI / 6) - 2.2 * (1 - Math.cos(22 * Math.PI / 6)), "11"); Text text12 = new Text(centerX + clockRadius * Math.sin(12 * Math.PI / 6) - 3.8 * (1 + Math.cos(24 * Math.PI / 6)) - 2.2 * Math.sin(24 * Math.PI / 6), centerY - clockRadius * Math.cos(12 * Math.PI / 6) + 8.8 - 3.8 * Math.sin(24 * Math.PI / 6) - 2.2 * (1 - Math.cos(24 * Math.PI / 6)), "12"); getChildren().addAll(circle, text1, text2, text3, text4, text5, text6, text7, text8, text9, text10, text11, text12); for(int i =1; i<= 60; i++){ double pointX1 = centerX + clockRadius * 0.95 * Math.sin(i * (2 * Math.PI) / 60); double pointY1 = centerY - clockRadius * 0.95 * Math.cos(i * (2 * Math.PI) / 60); double pointX2 = centerX + clockRadius * 1.0 * Math.sin(i * (2 * Math.PI) / 60); double pointY2 = centerY - clockRadius * 1.0 * Math.cos(i * (2 * Math.PI) / 60); if(i % 5 == 0) continue; 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(); } }
