android - AS中Module中没法使用Butterknife.有什么好的替代？

Question

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。。

以下是作者JakeWharton在14年12月的原话。。。

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.

Answer 1

Android Studio Prettify

这个插件自动生成findViewById等内容，你可以试试。
你说Butterknife不能用，应该是你用错了吧，你仔细看看是不是用错了。

Answer 2

module中好像也没看到别的，还是直接使用findViewById吧

Answer 3

现在基本不用butterknife了，直接封装一个方法在BaseActivity或BaseFragment

//BaseActivity
public <T extends View> T $(@IdRes int resId){
    return (T)super.findViewById(resId);
}
//BaseFragment
public <T extends View> T $(View layoutView, @IdRes int resId){
    return (T)layoutView.findViewById(resId);
}
//使用
TextView tvName=$(R.id.tv_name);

Answer 4

这个也行，功能比较多

Answer 5

最好使用系统自带的findviewyid来查找id,第三方的工具之间使用会存在冲突

Answer 6

RoboGuice?或者android annotation?
