[android]AndroidInject框架——我的第一个android小型框架

我不是女神ヾ 2022-03-31 03:42 274阅读 0赞

作为一个移动应用开发者，随着需求的日益增多，Android项目的越来越臃肿，代码量越来越大，

现在冷静下来回头看看我们的代码，有多少代码跟业务逻辑没什么关系的

所以，本人自不量力，在github上建了个开源项目，希望能一定程度地简化我的代码-。-

现在第一个版本完成，希望有兴趣的朋友能加入一起完善。

本人才疏学浅，代码中有写得不妥的地方希望大家不吝赐教哈！

**androidInject\_1.0.jar：**

主要的思想就是通过注解的方式，把我们要做的事情直接注入进来给我们，“不是我去调用对象，而是对象自己来找我”

现在刚写完了10个注解：

@AINoTitle， @AIFullScreen， @AILayout， @AIView， @AIBean， @AISystemService， @AIClick， @AIItemClick， @AILongClick， @AIItemLongClick

使用方法如下：

Activity中使用：
