Answer 1

您需要使用 ContextCompat.getColor() ，它是 Support V4 库的一部分(因此它适用于所有以前的 API)。

ContextCompat.getColor(context, R.color.my_color)

您需要通过将以下内容添加到应用 build.gradle 中的 dependencies 数组来添加 Support V4 库:

compile 'com.android.support:support-v4:23.0.1'

如果您关心主题，文档指定该方法将使用上下文的主题:

Starting in M, the returned color will be styled for the specified Context's theme
