Question

java MouseListener

for(i = 0; i<81;i++){
rrecordJLabel[i] = new JLabel(new ImageIcon("recordicon0.png"));
rrecordJLabel[i].setBounds(70,79 + 21*(i%9),184,21);
rrecordJLabel[i].addMouseListener(new MouseListener(.......){}
}

for(i = 0; i<81;i++){
rrecordJLabel[i] = new JLabel(new ImageIcon("recordicon0.png"));
rrecordJLabel[i].setBounds(70,79 + 21*(i%9),184,21);
rrecordJLabel[i].addMouseListener(new MouseListener(){

@Override
public void mouseClicked(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mouseEntered(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mouseExited(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mousePressed(MouseEvent arg0) {
// TODO Auto-generated method stub
rrecordJLabel[i].setIcon(new ImageIcon("recordicon0.png"));//!!!!!!!!
}

@Override
public void mouseReleased(MouseEvent arg0) {
// TODO Auto-generated method stub

}});
}
想通过鼠标事件对每个JLabel进行监听，
函数运行的时候!!!!!!!的地方i总是默认为81 怎么修改才好呢？？？

解决加分50
开始的那个：
for(i = 0; i<81;i++){
rrecordJLabel[i] = new JLabel(new ImageIcon("recordicon0.png"));
rrecordJLabel[i].setBounds(70,79 + 21*(i%9),184,21);
rrecordJLabel[i].addMouseListener(new MouseListener(.......){}
} 不要看 是多余的。。。。。

Answer 1

把那个内容里的方法改成这样就可以了。
@Override
public void mousePressed(MouseEvent arg0) {
// TODO Auto-generated method stub
JLabel label=(JLabel)arg0.getSource();
label.setIcon(new ImageIcon("recordicon0.png"));//!!!!!!!!
}

Answer 2

哈 不会啊

Answer 3

修改
public void mouseReleased(MouseEvent e) {
// TODO Auto-generated method stub
JLabel lab=(JLabel) e.getSource();
if(lab.equals(rrecordJLabel[0])){
//写你的代码
}
}});
