编辑 - 基于接受的答案的正确代码显示在此帖的底部。
我找到了一种方法（written by Andremoniy），可以在不点击单击和双击的情况下捕获双击和三击。它非常适合我的目的。
我对其进行了修改，以便可以通过实现调整点击间隔。这也很有效。
我的修改包括将其设为abstract class，定义实现必须定义的5个abstract方法（单次，双次，三次和“很多”点击的方法以及点击间隔调整者）。
以下是修改后的版本（println语句具有指导意义）：
public abstract class Click123 extends JPanel
{
public abstract void singleClick();
public abstract void doubleClick();
public abstract void tripleClick();
public abstract void manyClick();
public abstract int getFreq();
public Click123()
{
addMouseListener
(
new MouseAdapter()
{
Thread cp = null;
public void mouseClicked(MouseEvent e)
{
if (cp != null && cp.isAlive())
cp.interrupt();
if (e.getClickCount() == 1)
{
cp = new Thread(new ClickProcessor(new Callable<Void>() {
@Override public Void call() throws Exception {
singleClick();
return null;
}
}));
cp.start();
}
else if (e.getClickCount() == 2)
{
cp = new Thread(new ClickProcessor(new Callable<Void>() {
@Override public Void call() throws Exception {
doubleClick();
return null;
}
}));
cp.start();
}
else if (e.getClickCount() == 3)
{
cp = new Thread(new ClickProcessor(new Callable<Void>()
{
@Override public Void call() throws Exception {
tripleClick();
return null;
}
})
);
cp.start();
}
else manyClick();
} // mouseClicked
} // new MouseAdapter
); // add mouseListener
} // Click123
class ClickProcessor implements Runnable
{
Callable<Void> eventProcessor;
ClickProcessor(Callable<Void> eventProcessor)
{
this.eventProcessor = eventProcessor;
}
@Override public void run()
{
try
{
Thread.sleep(getFreq());
eventProcessor.call();
} catch (InterruptedException e) { System.out.println(e);}
catch (Exception e) { System.out.println(e);}
} // run
} // class ClickProcessor
} // class Click123
以下是实施计划：
public class NewMain1 {
static int INITIAL_CLICK_FREQUENCY = ((Integer)Toolkit.getDefaultToolkit()
.getDesktopProperty("awt.multiClickInterval"));
public static int CLICK_FREQUENCY;
static JSpinner spinner = new JSpinner();
static final JLabel ch = new JLabel("Click here to test");
public static void main(String[] args) {
CLICK_FREQUENCY = INITIAL_CLICK_FREQUENCY;
spinner = new JSpinner();
spinner.setModel(new SpinnerNumberModel(CLICK_FREQUENCY, 200, 900, 50));
spinner.addChangeListener(new ChangeListener() {
@Override
public void stateChanged(ChangeEvent e) {
CLICK_FREQUENCY = (int) spinner.getValue();
}
});
Click123 frame = new Click123(){
public void singleClick(){
JOptionPane.showMessageDialog(null,"Single click at " + CLICK_FREQUENCY);
}
public void doubleClick(){
JOptionPane.showMessageDialog(null,"Double click at " + CLICK_FREQUENCY);
}
public void tripleClick(){
JOptionPane.showMessageDialog(null,"Triple click at " + CLICK_FREQUENCY);
}
public void manyClick(){
JOptionPane.showMessageDialog(null,"Many clicks at " + CLICK_FREQUENCY);
}
public int getFreq(){
return CLICK_FREQUENCY;
}
};
frame.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
frame.setLayout(new FlowLayout());
frame.setSize(500, 300);
ch.setBorder(new EtchedBorder());
frame.add(ch);
frame.add(spinner);
frame.setVisible(true);
} // main
}
最初写的是Click123 extends JFrame。我修改了它（通过将顶行更改为extends JTextField）以使用类型为JTextField的网格。然后我添加了一个按钮来动态更改点击间隔。所以现在我有三个相同的（除了扩展类型）巨大的代码。
我的问题是：如何修改Click123，以便在不做任何更改的情况下，可以使用任何组件识别单击，双击和三击？
编辑 - 必要更改摘要（对于我自己的应用，abstract方法需要传递MouseEvent才能确定哪个组件触发了点击次数）：
班级定义：
public abstract class Click123<T extends Component>
{
public abstract void singleClick(MouseEvent e); // same for 3 others
...
public Click123(T target)
{
target.addMouseListener
(
new MouseAdapter() ...
} ...
}
final已添加为修饰符，以便传递MouseEvent：
public void mouseClicked(final MouseEvent e)
通过MouseEvent：
singleClick(e); // same for doubleClick and tripleClick and manyClick
接收MouseEvent以确定哪个组件触发了点击次数：
public void doubleClick(MouseEvent e)
实现：
frame = new JPanel();
new Click123(frame) {

泛型不是必需的。您只需要将MouseListener添加到Component。
public abstract class Click123 // doesn't extend anything
{
public Click123(Component comp)
{
comp.addMouseListener(new MouseAdapter() {
// ...
}));
}
}
现在您可以传递JFrame或任何您需要的Component：
Click123 handler = new Click123(myJFrame){
public void singleClick(){
JOptionPane.showMessageDialog(null,"Single click at " + CLICK_FREQUENCY);
}
// Other implementing methods here
}

泛型是解决方案的一部分。只需执行以下操作：
Click123<T extends Component> public Click123(T targetedComponent) { targetedComponent.addMouseListener而非addMouseListener JFrame或JPanel或其他内容，然后将其作为构造函数参数传递给new Click123。然后使用您使用JFrame。Click123
