Question

java 多个button添加同一个事件监听类判断是哪个button

Answer 1

Button a, b, c, d;
a = new Button("a");
......
this.addActionListener(a);
......
if (e.getSource() == a) {
//doing something here
} else if (e.getSource() == b) {
//doing something here
} else if (e.getSource() == c) {
//doing something here
} else if (e.getSource() == d) {
//doing something here
}
随便写的
主要就是下面的那些if判断那样子

Answer 2

可以为button设置事件触发命令，button.setActionCommand(String command); 在监听器里面执行
if(e.getActionCommand.equals("command")){ //dosomething}

Answer 3

e.getSource() == 按钮对象
