在这个程序中，我创建了进度条，但是在程序将所有文件从一个文件夹复制到另一个文件夹后启动。任何人都可以检查并给我一个适当的解决方案。
答案 0 :(得分：2)
出于您的目的，流程是错误的，您应该输入以下代码：
MoveTools service = new MoveTools();
service.moveDir(csvFileLocation);
在你的线程的run（）方法内。根据经验，需要长时间执行的工作（这是您需要显示进度的主要原因）应该放在线程的run（）方法中。
在moveDir（）工作中，它应该能够将进度报告给线程并让它相应地更新进度UI。例如，您可以添加一个侦听器接口，如：
public class MoveTools {
public static interface Listener {
void onProgress(String message, int currentProgress);
}
private Listener listener = null;
public void setListener(Listener listener) {
this.listener = listener;
}
在完成工作时，MoveTools可以向其监听器报告进度：
if (listener != null) {
listener.onProgress("Working...", 50);
}
然后调用线程可以设置监听器并更新进度条（现在请注意，工作需要接受MoveTools作为参数，因为它需要将监听器附加到它以获知正在进行的进度）：
public Work(MoveTools moveTools) {
moveTools.setListener(new MoveTools.Listener() {
@Override
public void onProgress(String message, int currentProgress) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
progressBar.setString(message);
progressBar.setValue(currentProgress);
}
});
}
});
}
注意我使用SwingUtilities.invokeLater（）更新了progressBar，因为你应该总是在事件调度线程（EDT）中修改GUI，而工作线程不是EDT。
答案 1 :(得分：1)
你有线程问题：
您的moveDir方法在 AWT 事件调度线程上运行，因此保留它。当它保持它时，不会执行任何屏幕更新（通过事件发送）。
此外，您的Work课程无法更新 GUI ，因为它正在另一个主题上运行。要访问 GUI ，您必须在 EDT 上发送活动。要做到这一点，有SwingUtilities.invokeLater()的便捷方法。这会为{strong> EDT 的任务队列添加Runnable。
