匕首和ButterKnife Android的区别 [英] Difference between Dagger and ButterKnife Android

问题描述

任何人都可以指出匕首和Butterknife之间的差异。我知道，Butterknife一种观点注射图书馆和匕首是一个依赖注入库。但是，在线文档似乎有点开销我。据Butterknife文档，你可以做非活性注射为好，这正是匕首呢？还是我误解的东西吗？ 如果任何人都可以解释简单来说，两者之间的差异将是巨大的。 谢谢！

Can anyone point out the difference between Dagger and Butterknife. I know that Butterknife is a view injection library and dagger is a dependency injection library. But the documentation online seems a bit overhead for me. According to Butterknife documentation you can do non-activity injections as well, which is what dagger does? Or did i misunderstood something? If anyone can explain the differences between the two in simple terms it would be great. Thanks!

推荐答案

ButterKnife是有针对性地只注入意见。非活动注入只是意味着你可以提供自己的看法根注入的意见（如使用手动充气的观点，等等）。 匕首是一个有点复杂。只要你指定它可以注入任何你想要的模块 - 类满足这些依赖（或者你可以使用构造函数注入）

ButterKnife is targeted to inject views only. Non-activity injection just means that you can provide your own view root to inject views from (like with manually inflated views, etc.). Dagger is a bit more complicated. It can inject anything you want as long as you specified Module - class which satisfies those dependencies (alternatively you can use constructor injection).

作为一个底线 - 我想说ButterKnife可以帮助你避免所有的样板$ C $下创建视图（又名（TextView中）findViewById（R.id.some_text_view）; 。仅此而已。引擎盖下它仍然没有一切无聊code，所以它不是一个真正的注入。

As a bottom line - I would say ButterKnife helps you to avoid all that boilerplate code for creating views (aka (TextView)findViewById(R.id.some_text_view);. Nothing more. Under the hood it still does all that boring code. So it is not really an injection..

另外值得一提的是杰克·沃顿是开发商为那些很酷的库之一：）

Also it worth mentioning that Jake Wharton is one of the developers for both those cool libs :)

没有太多有用的ButterKnife链接。它非常简单和直截了当的，所以希望你不需要任何

Don't have much of useful ButterKnife links. It really simple and straight forward though, so hopefully you don't need any
