前言:
最近发现之前封装的结构,如果作为一个module依赖来开发时
就不是很好用了.只能慢慢改了.
之前不好的地方：
1.Toolbar与ContentView写死在layout，如想要封装loadingView(根据请求状态,显示不同页面),非常麻烦.
2.Toolbar复用是通过include,改动即需要修改layout,也需要修改代码.
3.Presenter不能很好的控制Toolbar.
传送门:MVP实战心得(三)---封装Retrofit2.0+RxAndroid+RxBus
思路:
1.参考源码非NoactionBar主题，Toolbar应该与ContentView分开。
2.参考源码,base_layout的结构可以是LinearLayout里面一个ViewStub(生成toolbar),一个Framlayout(ContentVIew).
3.一个快速开发框架，应该有默认的模板，默认的样式。
4.Toolbar属于View范围，初始化应该在View里面，而不是在Presenter
5.参考AppCompatDelegate实现，提供多种默认的layout，根据layout生成不同的Toolbar。
6.继承BaseActivity,可以通过复写方法，控制是否需要Toolbar，以及自定义Toolbar。
7.ContentView应该使用Framlayout，可以被自由改造，比如：loadingView。。
8,参考AppCompatDelegate,具体实现使用ToolbarHelper的实现类,来代理创建设置Toolbar....BaseActivity不需要去关心这个过程.
来张丑丑的图:

新增的类:
UIView:
界面View,尽量让Frgament与Activity之间的切换,变的方便.只需改动极少的代码就能进行切换
Presenter,可以通过ToolbarHelper,控制Toolbar进行一些通用的设置.
ToolbarHelper
包含一些通用方法,如:getToolbar,setTitle,通过静态方法Create()传入不同的toolbarLayout的id,返回不同的实现类.
DefuatlToolbarHelperImplV1
默认的Toolbar实现.继承BaseToolBarHelperImpl
BaseToolBarHelperImpl
继承ToolbarHelper,否则创建toolbar,如果使用默认布局,则通过ViewStub
创建,如果使用自定义布局,则直接findview获取toolbar.
具体代码:
UIView:
