Android知识点-support迁移到androidx的映射关系

先扯两句

  作为一个苦逼的android开发,google那边有什么动作,我们都得跟着左手右手一个慢动作,右手左手慢动作重播。这不google已经推出androidx有段时间了,但是很多的项目还是基于support做的。尤其作为一个裸辞跳槽准备的我来说,更是苦逼到家了。这不看到一个不错的MVVM框架——MVVMHabit,想要玩一玩,结果一看一看源码,还是基于support做的,就想着自己改造成androidx的,可是如果有亲手改造过的应该了解,androidx与support的对应关系那真的基本就是没有关系了,尤其support.design库里的控件,好多都拆解成单独的库,而不再是全部整合在一起了。但是只要你还用jetpack,就绕不开design库的切换,除此之外,还有animated-vector-drawable、palette等等库。
  啥也不说了,动手改吧,多亏在官方提供了support到androidx的映射关系——工件映射,官方提供的是最新版的,懒得去看的,也可以往下看,是博客发布时的最新版,一般的也应该够用了。

映射关系怎么用

  其实起初的时候,只想着列一下下面的映射关系这篇博客就结束了,可以列到一半反应过来,或许有一些新入行的朋友,即便找到了映射关系,也不太清楚具体应该怎么用,毕竟我们在使用的时候,不是只写入下方的地址就好的,还需要添加对应的版本号,而这个版本号应该怎么确定呢?(了解这部分的大神可以直接跳过了,看下面的映射关系就可以)
  这里就以MVVMHabit中的animated-vector-drawable为例,首先我们先来看看下面的映射关系怎么用:

  PS:MVVMHabit这里使用的多module时的gradle提取统一配置,避免各个module版本不统一导致的异常,有兴趣了解的可以自行查找一下,我随便去百度搜了搜,找到了一个,可供参考:Gradle统一配置依赖版本,更详细的大家自己搜索吧

  有了support的gradle地址了,下面就该找Androidx的地址了,其实这一步最简单,只需要在浏览器中ctrl + F搜索一下就可以了(mac或者不支持ctrl + F快捷键的浏览器只需要在当前页搜索就行),本博客还没有发布,我这里就以官网上搜索的结果为例了:

  由于搜索框大小限制,我标注了一下,搜索的内容为:“com.android.support:animated-vector-drawable”,其实有一些特殊的,输入“animated-vector-drawable”也可以,毕竟我们只是为了找到这一条而已。

  映射关系找到了,那下一步就应该是查找Androidx库的最新稳定版本号了,我能想到的有两种方案(问老同事不算啊)。

方案一,通过Android官方获取(依照国际惯例,复杂的写)

  首先进入官方首页,在工件映射的页面也可以,搜索Androidx的路径。

  请原谅网速一般,页面跳转比较慢,翻译成中文了是因为开了chrome插件,无视之就好。具体选择的时候,我也不知道选第几个了,录制了gif后测试了一下,第一条其实也可以(如下图)。

  当然,也是有区别的,那就是在2019年9月5日更新版本中,是没有Alpha版本的,所以还是建议在搜索结果中选择最新的时间:

方案二,通过Android Studio

  其实大家在正常使用AS的时候,应该也会发现,在dependencies中,如果我们引用的库一旦有了新版本,就会有提示:

  因此我们可以利用AS的这个机制来获取自己想要使用的组件的最新版本是什么,由于不知道最新是什么,所以如果随意设置的时候,很可能已经超过了最新版本,所以这里我方法是设置为0,应该不会有比这个还小的版本了吧。

组件库版本获取

  可以看到,警告会提示我们最新版本的组件是1.1.0,正好也与上面通过官网查看的结果相互做了个验证。调整好版本号后是直接放到当前maven的dependencies中,还是放到多module封装的统一配置文件中就随大家开心了。

  好了,知道怎么用了,后面就上映射关系了
