问题如下：
点击一个按钮，弹出一个对话框，对话框里面包含确定和取消按钮，若点击确定，返回值为0，点击取消，返回值为1，若超过10秒不点击，提示窗口自动关闭，返回值为-5，后续可以根据返回值来做各种不同的判断。
1.TimerTest 主程序，先运行main方法，然后点击按钮。TimerTest.java
package com.chat.client;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import com.chat.ui.TimeDialog;
public class TimerTest extends JFrame {
private static final long serialVersionUID = 1L;
private static JButton button;
private static TimerTest TimerTest;
public static void main(String[] args) {
TimerTest = new TimerTest();
button = new JButton("按我");
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
TimeDialog d = new TimeDialog();
int result = d.showDialog(TimerTest, "对方想要和你语音是否接受?", 10);// TimerTest是程序主窗口类，弹出的对话框10秒后消失
System.out.println("===result: "+result);
}
});
button.setBounds(2, 5, 80,20);
TimerTest.getContentPane().setLayout(null);
TimerTest.getContentPane().add(button);
TimerTest.setSize(new Dimension(400,200));
TimerTest.setLocation(500,200);
TimerTest.setVisible(true);
TimerTest.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
2.自定义的Dialog。TimeDialog.java
package com.chat.ui;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class TimeDialog {
private String message = null;
private int secends = 0;
private JLabel label = new JLabel();
private JButton confirm,cancel;
private JDialog dialog = null;
int result = -5;
public int showDialog(JFrame father, String message, int sec) {
this.message = message;
secends = sec;
label.setText(message);
label.setBounds(80,6,200,20);
ScheduledExecutorService s = Executors.newSingleThreadScheduledExecutor();
confirm = new JButton("接受");
confirm.setBounds(100,40,60,20);
confirm.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
result = 0;
TimeDialog.this.dialog.dispose();
}
});
cancel = new JButton("拒绝");
cancel.setBounds(190,40,60,20);
cancel.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
result = 1;
TimeDialog.this.dialog.dispose();
}
});
dialog = new JDialog(father, true);
dialog.setTitle("提示: 本窗口将在"+secends+"秒后自动关闭");
dialog.setLayout(null);
dialog.add(label);
dialog.add(confirm);
dialog.add(cancel);
s.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
TimeDialog.this.secends--;
if(TimeDialog.this.secends == 0) {
TimeDialog.this.dialog.dispose();
}else {
dialog.setTitle("提示: 本窗口将在"+secends+"秒后自动关闭");
}
}
}, 1, 1, TimeUnit.SECONDS);
dialog.pack();
dialog.setSize(new Dimension(350,100));
dialog.setLocationRelativeTo(father);
dialog.setVisible(true);
return result;
}
}
