我想从方法中的颜色改变4个按钮,但是即使我按下其他按钮之一,计数器也会继续,并且我希望每个按钮都会计算出它自身,并从0开始而不是从另一个位置开始按钮已停止。如何在方法中改变按钮的颜色?
int count = 0;
public void ColourChange(JButton jButtonColour1){
//Changes the colours of the buttons, doesn't work good because it goes on counting for the other buttons too.
//returns the counter to 0 after it gets to 10.
if (count >= 10) {
count = 0;
}
count++;
//Makes sure it can be used at all the 4 buttons instead on just 1.
JButton setColour = jButtonColour1, jButtonColour2, jButtonColour3, jButtonColour4;
Color color;
switch (count) {
case 1:
count = 1;
setColour.setBackground(Color.BLACK);
break;
case 2:
count = 2;
setColour.setBackground(Color.RED);
break;
case 3:
count = 3;
setColour.setBackground(Color.PINK);
break;
case 4:
count = 4;
setColour.setBackground(Color.GREEN);
break;
case 5:
count = 5;
setColour.setBackground(Color.BLUE);
break;
case 6:
count = 6;
setColour.setBackground(Color.YELLOW);
break;
case 7:
count = 7;
setColour.setBackground(Color.MAGENTA);
break;
case 8:
count = 8;
setColour.setBackground(Color.cyan);
break;
case 9:
count = 9;
setColour.setBackground(Color.GRAY);
break;
case 10:
count = 10;
setColour.setBackground(Color.ORANGE);
break;
}
}
你是什么意思 “每个柜台”?代码中只有一个计数器变量。如果你想为每个按钮都有一个按钮,则需要为每个按钮声明一个按钮。 –
你想通过点击来改变你的按钮颜色吗? – Russiancold
count = 1,count = 2等在交换机中是没有意义的。想想为什么。 – Russiancold
