-------------------------------------------------------------------------------- /legacy/articles/2017.1.30/勘误：15 Kotlin 与 Java 共存 (2) .md: -------------------------------------------------------------------------------- 1 | # 勘误：15 Kotlin 与 Java 共存 (2) 2 | 3 | 在过去推送过的第15期视频中，涉及到一个泛型对比的点，当时文中提到“对于循环引用泛型参数的情况，Kotlin 无法实现”的结论是有问题的。感谢 @zhangdatou 指正，对应部分的内容修改如下： 4 | 5 | ## 3 泛型 6 | 7 | 整体上来讲，Kotlin 的泛型与 Java 的没什么大的差别，Java 的 ? 在 Kotlin 中变成了 *，毕竟 ? 在 Kotlin 当中用处大着呢。另外，Java 泛型的上限下限的表示法在 Kotlin 当中变成了 out 和 in。 8 | 9 | 不过，由于 Java 1.5 之前并没有泛型的概念，为了兼容旧版本，1.5 之后的 Java 仍然允许下面的写法存在： 10 | 11 | ```java 12 | List list = new ArrayList(); 13 | list.add("Hello"); 14 | list.add(1); 15 | for (Object o : list) { 16 | System.out.println(o); 17 | } 18 | ``` 19 | 而对应的，在 Kotlin 当中要用 List<*> 来表示 Java 中的 List —— 这本身没什么问题。那么我们现在再看一段代码： 20 | 21 | ```java 22 | public abstract class View

{ 23 | protected P presenter; 24 | } 25 | 26 | public abstract class Presenter{ 27 | protected V view; 28 | } 29 | ``` 30 | 这个其实是现在比较流行的 MVP 设计模式的一个简单的接口，我希望通过泛型来绑定 V-P，并且我可以通过泛型参数在运行时直接反射实例化一个 presenter 完成 V-P 的实例注入，这在 Java 当中是没有问题的。 31 | 32 | 那么在 Kotlin 当中呢？ 因为我们知道 View 和 Presenter 都有泛型参数的，所以我们在 Kotlin 当中就要这么写： 33 | 34 | ```kotlin 35 | abstract class View

>{ 36 | protected abstract val presenter: P 37 | } 38 | 39 | abstract class Presenter>>>{ 40 | protected abstract val view: V 41 | } 42 | ``` 43 | 一直写下去，最终陷入了死循环。编译器给出的解释是： 44 | 45 | >This type parameter violates the Finite Bound Restriction. 46 | 47 | 在 @zhangdatou 给我发邮件之前，我曾一直对此耿耿于怀，Kotlin 这么优秀的语言怎么还会有做不到的事情呢。原来不是做不到，而是我没有想到： 48 | 49 | ```kotlin 50 | abstract class View>> 51 | abstract class Presenter>> 52 | 53 | class MyView: View() 54 | class MyPresenter: Presenter() 55 | ``` 56 | 实际上我们需要 View 的泛型参数 P 只要是 Presenter 的子类即可，并且要求这个泛型参数 P 本身对应的泛型参数也需要是 View 的子类，而这个 View 其实就是最初的那个 View，那么这个 View 的泛型参数当然就是 P 了。有点儿绕，但这么写出来明显感觉比 Java 安全靠谱多了。 57 | 58 | -------------------------------------------------------------------------------- /legacy/articles/2017.1.30/如何优雅的在微信公众号中编辑代码.jpg:

-------------------------------------------------------------------------------- 1 | # Kotlin 1.1：我们都路上 2 | 3 | ##►1.1 RC 来了，Release 还会远吗？ 4 | 5 |

![](11RC-01.png)
6 | 7 | 去年 2 月 19 日 1.0 发版，我记得此前看到论坛上面开始讨论 1.0 API 趋于稳定的话题，想想都还挺兴奋呢，一不留神，Kotlin 1.0 在稳定奔跑一年之后，也终于迎来下一个版本：就在前天（17日），我留意到 Kotlin 官博发出了 1.1 RC(Release Candidate) 的消息，截止到目前，1.1 的所有开发工作都已经进入尾声，剩下的就只有我们期待的眼神了。 8 | 9 | ##►成长，一路有你 10 | 11 |
![](road.JPG)
12 | 13 | 2016 这一年发生了挺多的事情，最重要的就是 Kotlin 终于有一个正式的版本，开始了按部就班的日子：每两个月一个正式版本以及一个 1.1 的里程碑版本。接着，我们也很快的发现我们期待的功能都悄悄的走进了 Kotlin 的更新日志，Kotlin 正一天一天的成长起来。 14 | 15 | 不知道各位看官年龄几何，对我来说，C 和 C++ 太老，Java 虽然小了一些，可它诞生的时候我还在小学里面玩 Dos；而当我真正开始认识它们的时候却发现它们实在是太庞大了，有时候甚至觉得可怕，有时候更是没办法理解它们。它们是编程语言的长者，而我，只是一个年轻的程序员。 16 | 17 | Kotlin 则不一样了。它出现的不算早，大概 2010 年的样子吧，那个时候我刚刚闲来无事考了个软考中级的 “软件设计师”，一个在学校里面随处可见的“小黄书”背后的没有多大用处的考试，那个时候大概是我基础最好的时候吧。后来 Kotlin 逐渐成长起来，而我也逐渐脱离了象牙塔里的天真，冲向了努力干活历练自己的道路中间。 18 | 19 | ##►还记得，你与 Kotiln 的第一次相遇吗？ 20 | 21 |
![](zhiyin.jpg)
22 | 23 | 最早认识 Kotlin 还是在 15 年初，那时候我正热衷于编写 IntelliJ 的插件，尽管后面成果空空，不过一些个莫名其妙的后缀为 kt 的文件却着实让我头疼不已。尽管照着说明安装好 Kotlin 的插件，可因为版本不一致，始终无法编译过去，真是无可奈何啊。当时我还想，又有新语言啊，这可当真是学海无涯咯。 24 | 25 | 不过，随着接触的机会逐渐增多，我发现 Kotlin 解决了很多我对 Java 不满的问题，而它呢，却又全力支持着 Java 中的一切，始终让我们感觉不到我用了另外一种语言，语法的那点儿差异说真的比起不同语言背后的编程思维的差异来说，简直不值得一提。我在同时尝试了 groovy 和 scala 之后，觉得 Kotlin 才是我想要的，于是在 Kotlin 1.0 发布之际，我向 Bugly 公众号投稿文章：[Android 必备技能：最有可能接替Java的语言——Kotlin](http://www.println.net/post/Android-A-Powerful-Substitution-Kotlin) ，把我眼中的 Kotlin 向大家展现了出来。 26 | 27 | 28 | ##​►Kotlin 给你带来了什么？ 29 | 去年上半年有段时间经常奔波在北京和深圳之间，工作节奏“日新月异”，项目似乎进入了一种莫名其妙的状态，而我自己则犹如置身死水，所幸我也是上过王者的人了，也不枉费我那一段时间在上面投入的一个个不眠之夜吧。 30 | 31 |
![](wangzhe.jpg)
32 | 33 | 那段时间，我对项目的代码有我“自以为是的足够”的祸害的自由，于是我开始肆无忌惮的用 Kotlin 写一些模块，完全没有顾及合作开发的我们组唯一的妹子的感受。以及，这代码后来落入导师手中，我也算是坑他们不浅呐。不过，如果没有这段经历，或许我后来也不会有那么大的底气去在 10 月份斗胆录制视频，也自然不会去开公众号每周发几篇水文了。说来，得好好谢谢他们。 34 | 35 | 36 |
![](embarassed.png)
37 | 38 | 话说，自从摊上这么个事儿，我只好每天早晨 6 点起来或写写东西，或看看书，学点儿东西，每天节奏也极其规律，中午再也没没有精力跟小伙伴们组团王者了，因为我得睡一个小时。 39 | 40 | 年前我又在 Bugly 公众号发了一篇文章：[你为什么需要 Kotlin](http://mp.weixin.qq.com/s?__biz=MzA3NTYzODYzMg==&mid=2653578489&idx=1&sn=17d6e657d81c0daa345489271d305b36&chksm=84b3b6feb3c43fe8b0197850bf6ca8caefaa8045671f75ed6dec2171a681496365acfd0ebd33&mpshare=1&scene=23&srcid=0217VmFlkVB0LB4I2YRbvicL#rd)，结果大家都说我是被代码耽误了的段子手，呃。。我想说你们说的很对！ 41 | 42 |
![](right.jpg)
43 | 44 | 承蒙各位朋友厚爱，经常提及后续视频录制的问题，我正在尝试重新录制一套较为细致和基础的视频，目前讲义已经编写完毕，至于发布时间，那得看我啥时候录得完啦。 45 | 46 | 末了，建议大家有事儿没事儿也都写写，我最开始在公司内部写文章刷积分玩，后来发现自己写的东西经常需要复习；不仅如此，很多时候遇到一个问题，可能最终用某种方式解决了，你以为这个问题你是搞清楚了的，不过，一旦你企图将其形成文字，你就会发现问题的背后将会是更多的细枝末节。俗话说得好，好记性不如啪啪啪的机械键盘啊！ 47 | 48 |

-------------------------------------------------------------------------------- /legacy/articles/2017.2.6/Kotlin 1.1 Beta 2 发布~.md: -------------------------------------------------------------------------------- 1 | # Kotlin 1.1 Beta 2 重点更新 2 | 3 | ## 1 协程改包名风波 4 | 5 | 说真的，看到这个标题的时候我还挺兴奋，离 release 又近了一步。不过，看了这篇文章的时候，我就觉得也是醉醉的。发生了啥呢？ 6 | 7 | 原来，协程相关的依赖统统被标记为 experimental 了，以前叫： 8 | 9 | ```kotlin 10 | package kotlin.coroutines 11 | ``` 12 | 现在呢？ 13 | 14 | ```kotlin 15 | package kotlin.coroutines.experimental 16 | ``` 17 | 18 | 这意味着啥？意味着我们在这次更新之后，还得把原来的协程代码的包重新导入一遍，另外，如果你想使用协程，那么你还需要在配置当中呢启用它，例如 gradle 配置需要加入： 19 | 20 | ```gradle 21 | kotlin { 22 |     experimental { 23 |         coroutines 'enable' 24 |     } 25 | } 26 | ``` 27 | 28 | 你在升级所有的依赖的时候，确保它是兼容 1.1.0-beta-38 的，这一点很重要，不然等着报错吧！ 29 | 30 | 话说，为啥要这么搞呢？按照官方的说法就是，协程这个特性目前已经实现的非常不错了，内置 API 非常少，灵活扩展性也强，不过他们觉得这个东西还有很大的潜力，也不能就这样作为最终版本给大家放出来，而作为实验特性交给大家使用呢，更多地还是希望大家能提提意见啥的。嗯，说实在的，协程这个特性真不是个小特性。 31 | 32 | ## 2 兼容 1.0 33 | 34 | 话说，1.1 的编译器终于声称兼容 1.0 的源码了，这表明我们再也不用搞两个 IntelliJ 分别装 1.0 稳定版的插件和 1.1 Beta 版的插件了。 35 | 36 | 是的，就算你不用 1.1 的特性，你装 1.1 的插件，用 1.1 的编译器，写 1.0 的代码毫无压力！！ 37 | 38 | 什么？你问我试了没？当然，我一直用最新的插件，折腾地挺苦的 T T，劝诸君还是装稳定版吧，吃螃蟹要做好心理准备~！ 39 | 40 | ## 3 小结 41 | 42 | 浏览了一下 1.1Beta 2 的主要特性，其实就是改改包名，修几个小 Bug，大的改动基本没有了。如果大家想要尽早上手 1.1 的特性，那么就从现在开始吧~ 43 | 44 | -------------------------------------------------------------------------------- /legacy/articles/2017.3.13/Kotlin Script
