Question

1。父界面DaQiZhiBiao 生成子界面LiShuDu ，在子界面LiShuDu要判断父界面DaQiZhiBiao 中哪个button被按下了，
2。当子界面LiShuDu被关闭后，还要有值返回给父界面DaQiZhiBiao，并在保存在父界面DaQiZhiBiao中，
3。再次 按下父界面DaQiZhiBiao 中button，又生成子界面LiShuDu，重复步骤2，又保存值在父界面DaQiZhiBiao中，但要保持上次步骤2保存的值还在。如何实现啊？  郁闷啊，弄了好久，总是出错啊。高手们帮帮忙吧！public class DaQiZhiBiao implements ActionListener {
JButton b4;
JTextField t7;
LiShuDu liShuDu;
public DaQiZhiBiao()
{

t7 = new JTextField();
liShuDu.daQiZhiBiao=this;//提示这里出现了问题 b4 = new JButton("隶属度");
b4.addActionListener(
            new ActionListener()
        {
          public void actionPerformed(ActionEvent e)
          {           
           liShuDu=new LiShuDu();
             flag=1;//设了一个标志位
            }
        }
     );
}
public class LiShuDu implements ActionListener {
DaQiZhiBiao daQiZhiBiao;
public LiShuDu()
{ JButton b1 = new JButton("确定");
b1.addActionListener(
            new ActionListener()
        {
          public void actionPerformed(ActionEvent e)
          {
                try{
if(daQiZhiBiao.flag==1)
             {
             daQiZhiBiao.t7.setText("t7");
             daQiZhiBiao.t7.setEditable(false);
             f.hide();
             }
}
}

Answer 1

public DaQiZhiBiao()
{

t7 = new JTextField(); b4 = new JButton("隶属度");
b4.addActionListener(
            new ActionListener()
        {
          public void actionPerformed(ActionEvent e)
          {           
           liShuDu=new LiShuDu();
           liShuDu.daQiZhiBiao=this;//改到这里，上面的话liShuDu还是null呢，当然不行了
             flag=1;//设了一个标志位
            }
        }
     );
}
我没测，不过这么传值可不大好，看着挺乱的，可以用dialog之类的东西，也不用设什么标志为了就

Answer 2

zdsdiablo(十分钟年华老去) ： 
liShuDu=new LiShuDu();
liShuDu.daQiZhiBiao=this;这行提示：type mismatch  :  cannot convert from <anonymous implementation of ActionListener> to DaQiZhiBiao  怎么办呢？

Answer 3

可能是我说的不太清楚吧，
父界面中有3个button，当它们分别被按下时，调出同一个子界面。要在子界面判断是3个button中哪一个button被按下时，调出的子界面。
还有是上面zdsdiablo(十分钟年华老去) ：说的
liShuDu=new LiShuDu();
liShuDu.daQiZhiBiao=this;这行错误提示：type mismatch  :  cannot convert from <anonymous implementation of ActionListener> to DaQiZhiBiao  是怎么回事啊

Answer 4

楼主你的程序看起来有点乱
public class DaQiZhiBiao implements ActionListener {
JButton b4;
JTextField t7;
LiShuDu liShuDu;//这里都没创建一个对象,应该为LiShuDu liShuDu=new LiShuDu();
public DaQiZhiBiao()
{t7 = new JTextField();
liShuDu.daQiZhiBiao=this;//提示这里出现了问题b4 = new JButton("隶属度");
b4.addActionListener(
            new ActionListener()
        {
          public void actionPerformed(ActionEvent e)
          {          
          liShuDu=new LiShuDu();
           flag=1;//设了一个标志位
           }
        }
    );
}
你没把所有程序给出来,没得帮你调试下,楼主自己试下吧

所有的代码如下：帮我调试一下吧，我不会弄啊，好郁闷。
