MVP實(shí)戰(zhàn)心得(四)---封裝優(yōu)化,拆分Toolbar與ContentView

前言:

最近發(fā)現(xiàn)之前封裝的結(jié)構(gòu),如果作為一個module依賴來開發(fā)時
就不是很好用了.只能慢慢改了.

之前不好的地方：

1.Toolbar與ContentView寫死在layout，如想要封裝loadingView(根據(jù)請求狀態(tài),顯示不同頁面),非常麻煩.
2.Toolbar復(fù)用是通過include,改動即需要修改layout,也需要修改代碼.
3.Presenter不能很好的控制Toolbar.

傳送門:MVP實(shí)戰(zhàn)心得(三)---封裝Retrofit2.0+RxAndroid+RxBus

思路:

1.參考源碼非NoactionBar主題，Toolbar應(yīng)該與ContentView分開。
2.參考源碼,base_layout的結(jié)構(gòu)可以是LinearLayout里面一個ViewStub(生成toolbar),一個Framlayout(ContentVIew).
3.一個快速開發(fā)框架，應(yīng)該有默認(rèn)的模板，默認(rèn)的樣式。
4.Toolbar屬于View范圍，初始化應(yīng)該在View里面，而不是在Presenter
5.參考AppCompatDelegate實(shí)現(xiàn)，提供多種默認(rèn)的layout，根據(jù)layout生成不同的Toolbar。
6.繼承BaseActivity,可以通過復(fù)寫方法，控制是否需要Toolbar，以及自定義Toolbar。
7.ContentView應(yīng)該使用Framlayout，可以被自由改造，比如：loadingView。。
8,參考AppCompatDelegate,具體實(shí)現(xiàn)使用ToolbarHelper的實(shí)現(xiàn)類,來代理創(chuàng)建設(shè)置Toolbar....BaseActivity不需要去關(guān)心這個過程.

來張丑丑的圖:

新增的類:

UIView:

界面View,盡量讓Frgament與Activity之間的切換,變的方便.只需改動極少的代碼就能進(jìn)行切換
Presenter,可以通過ToolbarHelper,控制Toolbar進(jìn)行一些通用的設(shè)置.

ToolbarHelper

包含一些通用方法,如:getToolbar,setTitle,通過靜態(tài)方法Create()傳入不同的toolbarLayout的id,返回不同的實(shí)現(xiàn)類.

DefuatlToolbarHelperImplV1

默認(rèn)的Toolbar實(shí)現(xiàn).繼承BaseToolBarHelperImpl

BaseToolBarHelperImpl

繼承ToolbarHelper,否則創(chuàng)建toolbar,如果使用默認(rèn)布局,則通過ViewStub
創(chuàng)建,如果使用自定義布局,則直接findview獲取toolbar.
