如何将按钮的颜色更改为默认颜色
原标题:How to Change color of button to its default color

我正在创建一个 MCQ 应用程序, 其中有四个选项 < code> 按钮 < / code> 。 所有的按钮颜色都是默认的颜色。 每当用户点击正确的回答背景颜色 < code> 按钮 < / code> 更改为绿色, 当用户点击错误的选项 < code> 按钮 < / code > 更改为红色并显示正确的答案 < code > button 时, 我将创建默认颜色。 在用户点击下一个问题按钮后, 现在我要将所有选项 < code> Buttons 的背景颜色更改为初始状态, 即默认颜色。 我不知道如何操作 。 请帮助我将按钮图像修改为默认的颜色/ 。

问题回答

在 NFO BETTON 的 Click () 中设置一个代码, 将选项按钮颜色更改为您所选择的颜色 。

 onClick()
{
 button.setBackgroundColor(color);
}

The default color is not a color, it is StateListDrawable of many 9-patch images I suggest you set the background of buttons to be white for option buttons and then set it back to white when NEXT button is pressed.
