android中的多个按钮处理

如何解决android中的多个按钮处理

我有六个按钮

单击其中一个按钮时，请制作动画。因此，我将为其赋予动画效果（单击时会很大）。

因此，如果我给所有按钮一个动画，则单击一个按钮时必须将另一个按钮放回原处。大概只需激活一个按钮 一度 。 代码：

btn1 = findviewby<Button>(R.id.btn1)
btn2 = findviewby<Button>(R.id.btn2)
btn3 = findviewby<Button>(R.id.btn3)
btn4 = findviewby<Button>(R.id.btn4)
btn5 = findviewby<Button>(R.id.btn5)
btn6 = findviewby<Button>(R.id.btn6)

   btn1.setonClickListener {


            btn1.animate()
                .scaleXBy(0.1f)
                .scaleYBy(0.1f)
                .duration = 200

     // and if the other btn's (btn2,3,4,5,6) is get animation already go back on there position

        }

如果我对每个btn都执行以上代码，那么所有这些动画都会生效，这是不正确的。

我想当一个btn点击另一个btn回到那个位置

非常感谢

解决方法

解决方案：在一组按钮中，一次只能将一个按钮转换为给定的x，如果已经转换，则y的其余按钮将重置为原始位置。
