MVC架构 18 | 19 | MVC架构模式最初生根于服务器端的Web开发，后来渐渐能够胜任客户端Web开发，再后来因Android项目由XML和Activity/Fragment组成,慢慢的Android开发者开始使用类似MVC的架构模式开发应用. 20 | 21 | ![mvc架构模式](https://img-blog.csdnimg.cn/20181114163503719.jpg?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3ZpdGFtaW8=,size_39,color_FFFFFF,t_70) 22 | 23 | M层:模型层(model),主要是实体类,数据库,网络等存在的层面,model将新的数据发送到view层,用户得到数据响应. 24 | 25 | V层:视图层(view),一般指XML为代表的视图界面.显示来源于model层的数据.用户的点击操作等事件从view层传递到controller层. 26 | 27 | C层:控制层(controller),一般以Activity/Fragment为代表.C层主要是连接V层和M层的,C层收到V层发送过来的事件请求,从M层获取数据,展示给V层. 28 | 29 | 从上图可以看出M层和V层有连接关系,而Activity有时候既充当了控制层又充当了视图层,导致项目维护比较麻烦. 30 | 31 | ##### 1. MVC架构优缺点 32 | 33 | ###### A. 缺点 34 | 35 | 1. M层和V层有连接关系,没有解耦,导致维护困难. 36 | 37 | 2. Activity/Fragment中的代码过多,难以维护. 38 | 39 | Activity中有很多关于视图UI的显示代码，因此View视图和Activity控制器并不是完全分离的，当Activity类业务过多的时候，会变得难以管理和维护.尤其是当UI的状态数据，跟持久化的数据混杂在一起，变得极为混乱. 40 | 41 | ###### B. 优点 42 | 43 | 1. 控制层和View层都在Activity中进行操作，数据操作方便. 44 | 45 | 2. 模块职责划分明确.主要划分层M,V,C三个模块. 46 | 47 | #### 三. MVP架构 48 | 49 | ![MVP](https://img-blog.csdnimg.cn/2018112115535266.jpg?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3ZpdGFtaW8=,size_29,color_FFFFFF,t_70) 50 | 51 | MVP,即是Model,View,Presenter架构模式.看起来类似MVC,其实不然.从上图能看到Model层和View层没有相连接,完全解耦. 52 | 53 | 用户触碰界面触发事件,View层把事件通知Presenter层,Presenter层通知Model层处理这个事件,Model层处理后把结果发送到Presenter层,Presenter层再通知View层,最后View层做出改变.这是一整套流程. 54 | 55 | M层:模型层(Model),此层和MVC中的M层作用类似. 56 | 57 | V层:视图层(View),在MVC中V层只包含XML文件,而MVP中V层包含XML,Activity和Fragment三者.理论上V层不涉及任何逻辑,只负责界面的改变,尽量把逻辑处理放到M层. 58 | 59 | P层:通知层(Presenter),P层的主要作用就是连接V层和M层,起到一个通知传递数据的作用. 60 | 61 | ##### 1. MVP架构优缺点 62 | 63 | ###### A. 缺点 64 | 65 | 1. MVP中接口过多. 66 | 67 | 2. 每一个功能,相比于MVC要多写好几个文件. 68 | 69 | 3. 如果某一个界面中需要请求多个服务器接口,这个界面文件中会实现很多的回调接口,导致代码繁杂. 70 | 71 | 4. 如果更改了数据源和请求中参数,会导致更多的代码修改. 72 | 73 | 5. 额外的代码复杂度及学习成本. 74 | 75 | ###### B. 优点 76 | 77 | 1. 模块职责划分明显,层次清晰,接口功能清晰. 78 | 79 | 2. Model层和View层分离,解耦.修改View而不影响Model. 80 | 81 | 3. 功能复用度高,方便.一个Presenter可以复用于多个View,而不用更改Presenter的逻辑. 82 | 83 | 4. 有利于测试驱动开发,以前的Android开发是难以进行单元测试. 84 | 85 | 5. 如果后台接口还未写好,但已知返回数据类型的情况下,完全可以写出此接口完整的功能. 86 | 87 | #### 四. MVP架构实战(真枪实弹) 88 | 89 | ##### 1. MVP三层代码简单书写 90 | 91 | 接下来笔者从简到繁,一点一点的堆砌MVP的整个架构.先看一下XML布局,布局中一个Button按钮和一个TextView控件,用户点击按钮后,Presenter层通知Model层请求处理网络数据,处理后Model层把结果数据发送给Presenter层,Presenter层再通知View层,然后View层改变TextView显示的内容. 92 | 93 | 94 | ![MVP](https://img-blog.csdnimg.cn/20181123112130974.gif) 95 | 96 | ``` 97 | 98 | 106 | 107 |
