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~。~）

*/

}
public void paint(){

}
}
}
}
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();
}
}
