1. MVP簡介
M就是model，里邊放的是javabean蛾绎；
V就是View昆箕，就是Activity、Fragment租冠；
P就是Presenter鹏倘；
2. 自己使用
全局需要定義：
定義BaseView、BasePresenter肺稀，BaseView是View的父類第股，BasePresenter是Presenter的父類；
舉例：這里以請求HomeFragment的 BannerView輪播圖數(shù)據(jù)為例话原，結(jié)構(gòu)如下：
圖片.png
由上圖可以看出
1>：整個項目底部來回切換的多個fragment都是放在ui包下邊的；
2>：自己手動新建一個contract包诲锹，定義HomeFragmentContract接口繁仁，在里邊定義View繼承BaseView，里邊的方法用于給Activity或者Fragment回調(diào)归园；定義Presenter繼承BasePresenter黄虱，里邊的方法用于寫具體的聯(lián)網(wǎng)請求的邏輯代碼，目的就是把具體聯(lián)網(wǎng)請求的方法和給Activity庸诱、Fragment中提供的方法分開捻浦，達(dá)到最大程度解耦晤揣；
下邊以home首頁的fragment為例，定義4個包朱灿，分別是contract昧识、model、view盗扒、presenter跪楞；
3. 具體分析
3.1：定義HomeFragmentContract接口，代碼如下：
/**
* Email: 2185134304@qq.com
* Created by JackChen 2018/4/8 17:34
* Version 1.0
* Params:
* Description: ：Home主頁面
*/
public interface HomeFragmentContract {
//View(activity/fragment)繼承侣灶，需要實現(xiàn)的方法
interface View extends BaseView {
//設(shè)置輪播圖
void setBanner(BannerView mBanner, List<Object> arrayList);
void setOnclick(int position);
void setMarqueeClick(int position);
void setGridClick(int position);
void setGridClickThird(int position);
void setGridClickFour(int position);
void setNewsList2Click(int position, String url);
void setNewsList5Click(int position , String url);
}
//Presenter控制器
interface Presenter extends BasePresenter {
void setActivity(MainActivity activity);
//初始化
DelegateAdapter initRecyclerView(RecyclerView recyclerView);
BaseDelegateAdapter initBannerAdapter();
BaseDelegateAdapter initGvMenu();
BaseDelegateAdapter initMarqueeView();
BaseDelegateAdapter initTitle(String title);
BaseDelegateAdapter initList1();
BaseDelegateAdapter initList2();
}
}
contract中需要做的事：
1>：寫一個 View接口用于繼承BaseView甸祭，View就指的是Activity、Fragment褥影，里邊寫的方法就是Activity或者Fragment中所需要實現(xiàn)的方法名字池户；
2>：寫一個 Presenter接口繼承BasePresenter控制器，里邊的方法就是具體的聯(lián)網(wǎng)請求的方法凡怎；
3.2：自己定義一個 HomeFragmentPresenter校焦，只實現(xiàn) HomeFrgmentContract.Presenter，然后復(fù)寫所有的方法栅贴，而不實現(xiàn)HomeFragmentContract.View斟湃，目的是讓Activity或者Fragment實現(xiàn)，這里就是讓HomeFragment實現(xiàn)HomeFragmentContract.View檐薯，然后實現(xiàn)具體方法：
1>：HomeFrgmentContract中的View下邊的方法凝赛，是讓Activity、Fragment中回調(diào)的方法坛缕；
2>：HomeFragmentContract中的 Presenter下邊的方法墓猎，是在HomeFragmentPresenter中實現(xiàn)的方法，然后把具體的聯(lián)網(wǎng)請求的數(shù)據(jù)都寫到Presenter下邊的方法赚楚，只需要返回數(shù)據(jù)的結(jié)果給Activity或者Fragment就可以毙沾；

4. 總結(jié)
上邊啰啰嗦嗦這么多房揭，大家如果不是很清楚或者不是很理解的备闲，也沒有關(guān)系，可以不用看上邊的捅暴，只需要把我下邊的總結(jié)看懂就ok恬砂，照樣也可以很好的把MVP用在項目中。
1>：整個項目涉及到Activity或者Fragment包是ui包蓬痒，然后在ui包下邊創(chuàng)建底部所有的fragment包泻骤，如home、cart梧奢、my狱掂，表示首頁、購物車亲轨、我的趋惨；
2>：全局創(chuàng)建BaseView、BasePresenter惦蚊；
3>：然后針對于home首頁器虾，在里邊創(chuàng)建4個包，分別是contract蹦锋、model兆沙、view、presenter莉掂；
對于contract葛圃，創(chuàng)建HomeFragmentContract接口，需要做兩件事：
第一：定義View接口憎妙，繼承BaseView库正，然后定義一些方法，View下的方法作用是給Activity或者Fragment回調(diào)的厘唾；
第二：定義Presenter接口诀诊，繼承BasePresenter，然后定義一些方法阅嘶，Presenter下的方法作用是寫具體進(jìn)行聯(lián)網(wǎng)請求的代碼，來獲取網(wǎng)絡(luò)返回的數(shù)據(jù)；
4>：定義HomeFragmentPresenter讯柔，實現(xiàn)HomeFragmentContract.Presenter抡蛙，然后實現(xiàn)里邊的方法，把每一個需要填充數(shù)據(jù)的控件魂迄，所需要調(diào)用的接口的聯(lián)網(wǎng)請求都寫到對應(yīng)的方法中粗截，然后調(diào)用V層的回調(diào)方法，用于返回數(shù)據(jù)給Activity或者Fragment捣炬；
5>：讓HomeFragment實現(xiàn) HomeFragmentContract.View熊昌，然后實現(xiàn)里邊的方法，即就是V層中的方法湿酸，V層中的方法其實在P層中已經(jīng)獲取到了數(shù)據(jù)婿屹，這里只是通過回調(diào)接口把數(shù)據(jù)回傳給Activity或者Fragment的即可，然后在HomeFragment中直接獲取到數(shù)據(jù)后推溃，就可以給所需要的控件去填充數(shù)據(jù)就ok昂利；
5. 注意：
上邊自己只是舉了一個具體的應(yīng)用場景，我要說的是其他的所有頁面铁坎，不管是其他的Fragment或者是點擊任何一個Fragment中的按鈕或者點擊任何地方的按鈕進(jìn)入某個Activity蜂奸，都是可以使用上邊的方式來處理數(shù)據(jù)，也就是說每一個小模塊都需要創(chuàng)建對應(yīng)4個包硬萍，分別是contract扩所、model、view朴乖、presenter祖屏，然后在對應(yīng)的包下創(chuàng)建對應(yīng)的類，然后做對應(yīng)的事情就ok寒砖。
以上就是自己在項目中MVP具體的使用方法赐劣，如果還不是特別清楚的，可以給我發(fā)私信哩都，或者加我qq都是可以的
