java - 如何交换两个按钮的背景颜色？

Question

我需要创建一个方法，以便当单击第一个按钮时，保存其 id 和背景颜色，当按下第二个按钮时，它们会更改它们之间的背景颜色。我怎样才能做到这一点？

我曾想过这样的事情:

public void changeColor(View v){
    clicks = clicks++;
    if (clicks == 1){
        button1 = findViewById(v.getId());
        color1 = button1.getBackground();
    }
    if (clicks == 2){
        button2 = findViewById(v.getId());
        color2 = button2.getBackground();
        button1.setBackground(color2);
        button2.setBackground(color1);
    }
    if (clicks == 2){
        clicks = 0;
    }
}

Incase of button you type boton so it can't work of use 
boton ensure this line begin of your code
button1 = boton1
button2 = boton3
and also import java.awt package in your code

public void changeColor(View v) {
clicks = clicks++;
if (clicks == 1){
    button1 = findViewById(v.getId());
    color1 = button1.getBackground();
}
else if (clicks == 2) {
    button2 = findViewById(v.getId());
    color2 = button2.getBackground();
    button1.setBackground(color2);
    button2.setBackground(color1);
    clicks = 0;
 }
