私は画像を含む2つのjlabelsを持っています..もう一方がクリックされたときにラベルの画像を変更しようとしています..(ゲームなど)..問題があります..Thread.sleepを書き込むと、画像が表示されません変更..コードを参照してください:
public class Game extends JFrame{
private JLabel l1,l2;;
private boolean isClicked = false ,isClicked2 = false;
public Game(){
setLayout(new FlowLayout());
l1 = new JLabel(new ImageIcon(getClass().getResource("image1.png")));
add(l1);
l2 = new JLabel(new ImageIcon(getClass().getResource("image1.png")));
add(l2);
l1.addMouseListener(new MouseListener() {
@Override
public void mouseClicked(MouseEvent e) {}
@Override
public void mousePressed(MouseEvent e) {}
@Override
public void mouseReleased(MouseEvent e) {
if(isClicked2){
l1.setIcon(new ImageIcon(getClass().getResource("image2.png")));
try {
Thread.sleep(1000);
l1.setIcon(new ImageIcon(getClass().getResource("image1.png")));
l2.setIcon(new ImageIcon(getClass().getResource("image1.png")));
isClicked2 = false;
isClicked = false;
}catch(InterruptedException ex){}
}
else{
l1.setIcon(new ImageIcon(getClass().getResource("image2.png")));
isClicked = true;
}
}@Override public void mouseEntered(MouseEvent e){}@Override public void mouseExited(MouseEvent e){}
});
l2.addMouseListener(new MouseListener() {
@Override
public void mouseClicked(MouseEvent e) {}
@Override
public void mousePressed(MouseEvent e) {}
@Override
public void mouseReleased(MouseEvent e) {
if(isClicked){
try {
l2.setIcon(new ImageIcon(getClass().getResource("image2.png")));
Thread.sleep(1000);
l2.setIcon(new ImageIcon(getClass().getResource("image1.png")));
l1.setIcon(new ImageIcon(getClass().getResource("image1.png")));
isClicked = false;
isClicked2 = false;
}catch(InterruptedException ex){}
}
else{
l2.setIcon(new ImageIcon(getClass().getResource("image2.png")));
isClicked2 = true;
}
}@Override public void mouseEntered(MouseEvent e){}@Override public void mouseExited(MouseEvent e){}
});
}
public static void main(String[] args) {
Game g = new Game();
g.setTitle("Fint the same");
g.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
g.pack();
g.setVisible(true);
}
}
それを実行し、最初のラベルをクリックします。
