谷歌有他们的颜色 - 指南 http://www.google.com/design/spec/style/color.html，那么如何随机接收一个颜色呢？有没有办法指定表中的数字并从表的所有颜色中接收随机颜色？
例如getMatColor(100);:
编辑 - 结果：（图标颜色）
迟到总比不到好。
如果真正的目的是获得随机材质颜色，我的新回应type的颜色。
添加 array.xml 文件（来自@8m47x）

添加以下方法以从父类型中选择随机颜色
private int getMatColor(String typeColor)
{
int returnColor = Color.BLACK;
int arrayId = getResources().getIdentifier("mdcolor_" + typeColor, "array", getApplicationContext().getPackageName());
if (arrayId != 0)
{
TypedArray colors = getResources().obtainTypedArray(arrayId);
int index = (int) (Math.random() * colors.length());
returnColor = colors.getColor(index, Color.BLACK);
colors.recycle();
}
return returnColor;
}
Usage
txt.setTextColor(getMatColor("500"));
