返回点击按钮的索引？ [英] Return the index of clicked button?

问题描述

我有30个按钮[]数组。我有一个变量buttonClicked。当我preSS的按钮，我怎么能得到索引和存储在buttonClicked指数是多少？

感谢：）

  JButton的[]按钮=新的JButton [30];
        的for（int i = 1; I＆LT; = 30;我++）
        {
            INT btnNumber =（ⅰ大于10＆安培;＆放大器; I＆下; = 20）？ （31  -  I）：我;            System.out.printf（I =％d个，btnNumber =％D％N，我，btnNumber）;
            按钮[btnNumber  -  1] =的新的JButton（标签+ btnNumber）;
            //键[btnNumber  -  1] .setBorder（BorderFactory.createEmptyBorder（5,5，5,5））;
            按钮[btnNumber  -  1] .setBorder（BorderFactory.createEtchedBorder（））;
            按钮[btnNumber  -  1] .setOpaque（真）;
            按钮[btnNumber  -  1] .setBackground（Color.white）;            //会将播放器1个按钮1,3,5,7,9和播放器2件按钮2,4,6,8,10
            如果（（btnNumber  -  1） - ; 10）
            {
                如果（（（btnNumber  -  1）％2）== 0）
                {
                    按钮[btnNumber  -  1] .setIcon（piece1）;
                }
                其他
                {
                    按钮[btnNumber  -  1] .setIcon（piece2）;
                }
            }
            centerPanel.add（按钮[btnNumber  -  1]）;
        }
 

//下面是什么，我试图做的，我知道是不正确的。

 公共无效移动（）
{
动= dice.getDiceResult（）;
INT buttonClicked = 0;如果（playerOneTurn =真）
{
buttonclicked + diceResult（）;
}
 

//修改

 公共类MyActionListener实现的ActionListener {
骰子骰子;
私人布尔playerOneTurn = TRUE;
私人布尔playerTwoTurn = FALSE;
    @覆盖
    公共无效的actionPerformed（ActionEvent的五）
{
    字符串NUM = e.getActionCommand（）;
    INT指数=的Integer.parseInt（NUM）;
    INT此举= dice.getDiceResult（）;
    INT positionLanding = 0;    如果（playerOneTurn =真）
    {
        positionLanding =指数+移动;
        positionLanding.setIcon（piece1）; //我怎么可以设置图像图标这个位置吗？
    }}
}
 

解决方案

1）<一个href=\"http://docs.oracle.com/javase/7/docs/api/javax/swing/JComponent.html#putClientProperty%28java.lang.Object,%20java.lang.Object%29\"相对=nofollow> putClientProperty

 按钮[i] [j]的.putClientProperty（列，我）;
按钮[i] [j]的.putClientProperty（行，J）;
按钮[i] [j]的.addActionListener（新MyActionListener（））;
 

和<一个href=\"http://docs.oracle.com/javase/7/docs/api/javax/swing/JComponent.html#getClientProperty%28java.lang.Object%29\"相对=nofollow> getClientProperty

 公共类MyActionListener实现的ActionListener {@覆盖
公共无效的actionPerformed（ActionEvent的五）{
    JButton的BTN =（JButton的）e.getSource（）;
    的System.out.println（栏点击+ btn.getClientProperty（列）
            +，行+ btn.getClientProperty（行））;
}
 

2） ActionCommand

I have got an array of 30 buttons []. I have a variable buttonClicked. When I press the button how can I get the index and store the index number in the buttonClicked?

Thanks :)

JButton [] buttons = new JButton[30]; 


        for(int i = 1; i <= 30; i++)
        {       
            int btnNumber = (i > 10 && i <= 20) ? (31 - i) : i;

            System.out.printf("i = %d, btnNumber = %d%n", i, btnNumber);
            buttons[btnNumber - 1] = new JButton("label " + btnNumber);
            //buttons[btnNumber - 1].setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
            buttons[btnNumber - 1].setBorder(BorderFactory.createEtchedBorder());
            buttons[btnNumber - 1].setOpaque(true);
            buttons[btnNumber - 1].setBackground(Color.white);

            //Puts the player 1 piece on button 1,3,5,7,9 and player 2 piece on button 2,4,6,8,10 
            if ((btnNumber - 1) < 10) 
            { 
                if (((btnNumber - 1) % 2) == 0) 
                { 
                    buttons[btnNumber - 1].setIcon(piece1); 
                } 
                else 
                { 
                    buttons[btnNumber - 1].setIcon(piece2); 
                } 
            } 
            centerPanel.add(buttons[btnNumber - 1]); 
        } 

//Below is what I am attempting to do, I know is not correct.

public void move()
{
Move = dice.getDiceResult();
int buttonClicked = 0;

if(playerOneTurn =true)
{
buttonclicked + diceResult();
}

//revised

public class MyActionListener implements ActionListener {
Dice dice;
private boolean playerOneTurn = true;
private boolean playerTwoTurn = false;
    @Override
    public void actionPerformed(ActionEvent e) 
{
    String num = e.getActionCommand();
    int index = Integer.parseInt(num);
    int move = dice.getDiceResult();
    int positionLanding = 0;

    if(playerOneTurn = true)
    {
        positionLanding = index + move;
        positionLanding.setIcon("piece1");//how can I set the image Icon to this position?
    }

}
}

解决方案

1) putClientProperty

buttons[i][j].putClientProperty("column", i);
buttons[i][j].putClientProperty("row", j);
buttons[i][j].addActionListener(new MyActionListener());

and getClientProperty

public class MyActionListener implements ActionListener {

@Override
public void actionPerformed(ActionEvent e) {
    JButton btn = (JButton) e.getSource();
    System.out.println("clicked column " + btn.getClientProperty("column")
            + ", row " + btn.getClientProperty("row"));
}

2) ActionCommand
