我想改变基于所述按钮的状态的颜色。我试图用一个颜色选择阴影颜色，但它崩溃的应用程序。它似乎并不想用一个选择该属性。所以，现在我想用在运行时做
I want to change the color based on the state of the button. I tried using a color selector for the shadow color but it crashed the app. It didn't seem to want to use a selector for that attribute. So, now I am trying to do it at run time using

推荐答案
此方法用于更改包含的按钮（也内的文本的影子，你应该低音android.R.color.black直接，它的ID黑色，而不是本身的颜色，请参阅参考资料类的更多信息。）
This method is used to change the shadow on the text contained inside the button (also, you should bass android.R.color.black directly, it's the ID of the black color, not the color itself, see the Resources class for more info.)
