说是Module中的R文件下的id不是final的。然后Butterknife就不行。。。
估计别的注解类型的也不好使吧。。。于是乎有什么办法么。。

Yes this is not supported. This is a tradeoff between ease-of-use and what I tolerate as a sane API.
The only way to accomplish something like this is to allow string values like this:
@InjectView(name = "content_frame") protected FrameLayout
contentFrame; The downside's to this are:The downside's to this are:
It's not rename-safe or compile-safe (kind of). If you open the layout XML for this and do an IDE-backed rename operation it will not catch this string and update it. It also means you can (technically) compile the above code if there is no content_frame ID that exists. Now the compilation will eventually fail because the generated code will become invalid.
It's hard to know what R class to reference in the generated code, especially when you take into consideration the fact that you can use references to IDs that exist in libraries that you are referencing.
It forces us to have defaults for both the value and name properties on each annotation which means you can write @InjectView Foo foo and Butter Knife will have to fail the builder rather than javac.
Because of these facts, I have chosen not to support library projects.
One way that this could potentially be solved is to use a Gradle plugin rather than an annotation processor. I don't have the time to explore something like that for a few months though.

今ではバターナイフはほとんど必要ありません。メソッドを BaseActivity または BaseFragment に直接カプセル化するだけです
