这篇文章给大家介绍使用JavaFX制作一个简单的日历,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。

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; 
 
/**

 * @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(); 
 }

  return w; 
 } 
 public void setW(double w) { 
  this.w = w; 
  paint(); 
 }

  paint();

   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(); 
 } 
}
