使用时间延迟将Swing组件中的String数组的内容显示为迭代。 JAVA

问题描述

我有一个字符串数组，我试图（逐个）显示为Java Swing组件中的幻灯片。我也试图在迭代之间添加延迟时间。

I have an array of strings which I'm trying to display (one by one) as a slideshow in a Java Swing component. I am also trying to add a delay time between the iterations.

我试图通过使用JTextArea来实现这一点，并添加了一个动作侦听器。这是我现在的代码：

I attempted to do this by using a JTextArea, with an action listener added to it. Here is the code I have right now:

private class myActionListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        // A BUNCH OF TEXT PROCESSING

        //NOTE: myInfo.getContents() returns an ArrayList<myType>.
        Iterator<myType> iterator = myInfo.getContents().iterator();

        int i = 0;
        while (iterator.hasNext()) {
            myTextArea.setText(iterator.next().toString());
            // to add time betweeen iterations i wanted to use the thread
            // delay method.
        }
    }
}

我的代码无效，因为JTextArea没有动作侦听器。

My code is not working because JTextArea doesn't have an action listener.

更新
注意：许多回复声明我应该为JTextArea使用ActionListener ;但是，Eclipse没有告诉我JTextArea有一个名为addActionListener的方法。

UPDATENOTE: Many replies stated that I should use an ActionListener for the JTextArea; However, Eclipse is not showing me that JTextArea has a method called addActionListener.

我有点困在这里，你认为哪种Java Swing组件最适合这种情况？

我的数组中的文字可能很长，所以单行标签不是一个好选择。

The text in my array may be long, so a one lined label would not be a good choice.

还有什么其他选择或者我有办法吗？

What other alternatives or approaches do I have?

非常感谢，任何帮助和建议都表示赞赏。

Thank you very much, any help and suggestions are appreciated.

推荐答案

将 ActionListener 与 javax.Swing.Timer 结合使用。分配给计时器的 ActionListener 将定期调用指定的延迟。

Use your ActionListener in combination with a javax.Swing.Timer. The ActionListener assigned to the Timer will be called on regular intervals with the specified delay.
