我试图让JFileChooser记住上一个位置打开的位置,然后下次打开那里,但似乎不记得了。我必须打开两次: 在第一次运行它工作正常。但是在第二次运行时,仍然存在从第一次运行锁定的路径。我必须打开JFileChooser对话框两次以获得更新的路径......
//Integrate ActionListener as anonymous class
this.openItem.addActionListener(new java.awt.event.ActionListener() {
//Initialise actionPerformed
@Override
public void actionPerformed(java.awt.event.ActionEvent e) {
//Generate choose file
this.chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int returnVal = this.chooser.showOpenDialog(PDFcheck.this.openItem);
if (this.theOutString != null){
this.chooser.setCurrentDirectory(new File(this.theOutString)); }
if(returnVal == JFileChooser.APPROVE_OPTION) {
//theOutString = fc.getSelectedFile().getName();
this.theOutString = this.chooser.getSelectedFile().getPath();
System.out.println("You chose to open this file: " + this.theOutString);}
}
private String theOutString;
private final JFileChooser chooser = new JFileChooser();
});

问题是你首先显示文件选择器对话框,然后你只设置它的当前目录。
首先应首先设置当前目录,然后显示对话框:
if (this.theOutString != null)
this.chooser.setCurrentDirectory(new File(this.theOutString));
int returnVal = this.chooser.showOpenDialog(PDFcheck.this.openItem);
