前言:

最近發(fā)現(xiàn)之前封裝的結(jié)構(gòu),如果作為一個(gè)module依賴來開發(fā)時(shí) 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.

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(gè)ViewStub(生成toolbar),一個(gè)Framlayout(ContentVIew). 3.一個(gè)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(gè)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.

具體代碼:

UIView:

package com.baozi.mvpdemo.ui.view;import android.app.Activity;import android.content.res.Resources;import android.support.v4.app.Fragment;import android.support.v7.app.ActionBar;import android.support.v7.widget.Toolbar;import android.view.View;/** * Created by baozi on 2017/2/20. * 用戶頁面,操作頁面，對應(yīng)Activity,frgament... */public interface UIView extends BaseView { /** * id查找控件 * 省去findviewById的強(qiáng)轉(zhuǎn)操作 * * @param viewId 控件id * @param <V> 控件類型 * @return V extends View */ <V extends View> V findView(int viewId); /** * res資源獲取 * * @return */ Resources getResources(); /** * 回退 */ void onBack(); /** * 是否自定義布局 * * @return */ boolean isCustomLayout(); /** * 是否使用MaterialDesign風(fēng)格 * * @return */ boolean isMaterialDesign(); /** * MaterialDesign風(fēng)格,普通風(fēng)格之間轉(zhuǎn)換 * * @param isMaterialDesign */ void setMaterialDesignEnabled(boolean isMaterialDesign); /** * 獲取Acitivity * * @return */ Activity getActivity(); /** * Frgament跳轉(zhuǎn). * * @param tofragment */ void startFragment(Fragment tofragment); /** * Frgament跳轉(zhuǎn). * * @param tofragment */ void startFragment(Fragment tofragment, String tag); /** * 獲得getSupportActionBar * * @return */ ActionBar getSupportActionBar(); /** * 設(shè)置getSupportActionBar * * @param toolbar * @return */ void setSupportActionBar(Toolbar toolbar); /** * 獲得ToolbarHelper,Presenter可以通過ToolbarHelper的來控制toolbar */ ToolbarHelper getToolbarHelper();}
