代码示例

代码示例来源：origin: stackoverflow.com

// Create icon
Icon icon = new ImageIcon(getClass().getResource("/foo/bar/baz.png"));

// Create label
final JLabel lbl = new JLabel("Hello, World", icon, JLabel.LEFT_ALIGNMENT);

// Create button
JButton btn = new JButton("Click Me");
btn.addActionListener(new ActionListener() {
 public void actionPerformed(ActionEvent evt) {
  // Remove icon when button is clicked.
  lbl.setIcon(null);

  // **IMPORTANT** to call revalidate() to cause JLabel to resize and be repainted.
  lbl.revalidate();
 }
});

代码示例来源：origin: stackoverflow.com

int w = img.getWidth();
 int h = img.getHeight();
 frame.setSize(w, h);        // I just did that to make the example easier to understand
 JLabel label = new JLabel(new ImageIcon(img));  // so your "background" label with the map image
 // we need this dot label somewhere else and it must be final
 final JLabel dot = new JLabel(new ImageIcon(redDot));  // and your dot label with the dot image as icon
 label.add(dot);
 frame.add(label);
 label.setBounds(0, 0, w, h);    // just for the example, the map-label is set to  fill the frame
 dot.setBounds(50, 50, 60, 60);  // setBounds will handle both: location and size
 frame.pack();  // pack will do all the stuff to make sure everything is painted and has the correct size when the window becomes visible
 // and here comes the animation:
 // my solution is to use a swing timer. Swing timers execute in a background thread and are perfectly suited to "update" any swing component without blocking the User Input thread.
 // this timer will call the actionPerformed() of the ActionListener every 500 ms
 Timer timer = new Timer(500, new ActionListener(){
   @Override
   public void actionPerformed(ActionEvent e){
     Point location = dot.getLocation();    // get current location of the dot
     dot.setLocation(location.x + 10, location.y + 10);  // just set a new location 10 px further right and further down
     dot.revalidate();  // revalidate, so the updated position will be taken into account when the dot label will get painted again
   }
 });
 timer.start();   // start the timer and it will immediately start moving your dot on the img
