毕设项目:MVP+Retrofit2+okhttp3+rxjava+butterknife搭建的景区信息APP_01篇

引言

终于毕业了,我把我的毕设贡献给大家吧,在实习阶段,公司框架主要都是使用的mvp+retrofit+okhttp3+rxjava的框架搭建的,我也根据自己的理解,搭建了一个项目作为毕设,关于mvp的优缺点我就不多说了,但是的确能让业务逻辑变得更加清晰。基于这个项目我就在此做一个抛砖引玉的效果吧,希望大家看了之后有自己的感悟。


界面欣赏

界面的话,因为是周末抽时间搞得毕设,比较匆忙,希望大家不要见怪,其次,对于景区地区的接口地址,使用的网上的收费的,这接口可搞死我了,居然有验证,当时用的时候没有考虑到,差点把我搞吐血了

底层架构

整个项目采用了分层的理念整个底层架构在common包中。

view层以及presenter层的基础接口在BaseContract

public interface BaseContract {
    // 基本的界面职责
    interface View {
        // 公共的:显示一个字符串错误
        void showError(String error);

        // 公共的:显示进度条
        void showLoading();

        // 支持设置一个Presenter
        void setPresenter(T presenter);
    }

    // 基本的Presenter职责
    interface Presenter {
        // 共用的开始触发
        void start();

        // 共用的销毁触发
        void destroy();
    }
}

BasePresenter继承自BaseContract的Presenter接口我这里只是进行了简单拓展,具体的扩展,大家可以根据自己的具体逻辑进行设定。

package com.haodong.scenictourguide.common.presenter;

/**
 * describe : basePresenter
 * author linghailong
 * date on 2019/1/26
 * email [email protected]
 */
public class BasePresenter<T extends BaseContract.View> implements BaseContract.Presenter {
    private T mView;

    public BasePresenter(T view) {
        setView(view);
    }

    /**
     * 设置一个View,子类可以复写
     */
    @SuppressWarnings("unchecked")
    protected void setView(T view) {
        this.mView = view;
        this.mView.setPresenter(this);
    }

    /**
     * 给子类使用的获取View的操作
     * 不允许复写
     *
     * @return View
     */
    protected final T getView() {
        return mView;
    }

    @Override
    public void start() {
        // 开始的时候进行Loading调用
        T view = mView;
        if (isViewAttached()) {
            view.showLoading();
        }
    }
    public boolean isViewAttached() {
        return mView != null;
    }

    @SuppressWarnings("unchecked")
    @Override
    public void destroy() {
        T view = mView;
        mView = null;
        if (view != null) {
            // 把Presenter设置为NULL
            view.setPresenter(null);
        }
    }
}

而在View层,主要对Fragment以及Activity进行了简单封装。在activity中,借鉴了模板模式的思想,把常用的类都进行了编写。我这里写得比较生硬,大家可以使用动态代理的方式进行进一步拓展。

网络层

以上是mvp最基础的底层逻辑的搭建。这部分工作仅仅完成了对view层的封装,而如今的app中,网络层是不可或缺的。
网络层时下最流行的无非是okhttp3+retrofit+rxjava,okhttp太强大了,在看了他的源码之后真的是受益匪浅。而retrofit是对OKhttp3请求方法的封装,源码也用到了很多的设计模式,比如动态代理,抽象工厂,适配器等等等等,目前还没有研究完,等之后研究完了也分享下心得。Rxjava的响应式编程是它的精髓,真的很好用,能完美地进行线程的切断调度。在子线程与主线程之间的调度过程中,至少可以避免使用handler。话不多说,先来看看代码吧。

  1. 首先是创建一个简单工厂类,管理retrofit
package com.haodong.scenictourguide.common.net;

import com.haodong.scenictourguide.common.app.ConfigKeys;
import com.haodong.scenictourguide.common.app.TourGuide;

import java.util.concurrent.TimeUnit;

import okhttp3.Cache;
import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;
import retrofit2.converter.scalars.ScalarsConverterFactory;

/**
 * describe :

 */
public class RestCreator {
    private static final class OkHttpHolder {
        private static final int TIME_OUT = 60;
        private static final int CACHE_SIZE = 20 * 1024 * 1024;
        private static final OkHttpClient OK_HTTP_CLIENT = new OkHttpClient.Builder().connectTimeout
                (60, TimeUnit.SECONDS)
                .retryOnConnectionFailure(true)
                .addNetworkInterceptor(new CacheIntercepter())
                .cache(new Cache(TourGuide.getApplicationContext().getCacheDir(), CACHE_SIZE))
                .build();
    }

    /*单例模式的静态颞部类*/
    private static final class RetrofitHolder {

        /*baseAPI*/
//        private static final String BASE_URL = TourGuide.getConfiguration(ConfigKeys.API_HOST);

        /*建造者模式*/
        /*添加转换器*/
        private static final String BASE_URL = "http://www.baidu.com";
        private static final Retrofit RETROFIT_CLIENT = new Retrofit.Builder().baseUrl(BASE_URL)
                .client(OkHttpHolder.OK_HTTP_CLIENT)
                .addConverterFactory(ScalarsConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build();
    }

    private static final class RxRestServiceHolder {
        private static final RxRestService REST_SERVICE =
                RetrofitHolder.RETROFIT_CLIENT.create(RxRestService.class);
    }

    public static RxRestService getRxRestService() {
        return RxRestServiceHolder.REST_SERVICE;
    }

}

我不是直接用的接口进行的请求,我用的json转化工具是fastjson,当初也是头铁,听说fastjson比Gson效率更高,对retrofit有进行了一次封装,方便请求和转化。正好自己也在学习设计模式,也就拿来练练手了。

最后是RestService

package com.haodong.scenictourguide.common.net;

import java.util.WeakHashMap;

import io.reactivex.Observable;
import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import okhttp3.ResponseBody;
import retrofit2.http.Body;
import retrofit2.http.DELETE;
import retrofit2.http.FieldMap;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.GET;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.PUT;
import retrofit2.http.Part;
import retrofit2.http.QueryMap;
import retrofit2.http.Streaming;
import retrofit2.http.Url;

/**
 * describe :
 * date on 2019/1/26
 * author linghailong
 * email [email protected]
 */
public interface RxRestService {
    @GET
    Observable<String> get(@Url String url, @QueryMap WeakHashMap<String, Object> params);

    @FormUrlEncoded
    @POST
    Observable<String> post(@Url String url, @FieldMap WeakHashMap<String, Object> params);

    @POST
    Observable<String> postRaw(@Url String url, @Body RequestBody body);

    @FormUrlEncoded
    @PUT
    Observable<String> put(@Url String url, @FieldMap WeakHashMap<String, Object> params);

    @PUT
    Observable<String> putRaw(@Url String url, @Body RequestBody body);

    @DELETE
    Observable<String> delete(@Url String url, @QueryMap WeakHashMap<String, Object> params);

    @Streaming
    @GET
    Observable<ResponseBody> download(@Url String url, @QueryMap WeakHashMap<String, Object> params);

    @Multipart
    @POST
    Observable<String> upload(@Url String url, @Part MultipartBody.Part file);
}

这样做的好处是restService可以不用写太多方法,而且比较通用。反正萝卜青菜各有所爱吧,仅仅给大家作为观赏。
然后是自己建立了一个每局,封装了请求的方式:

package com.haodong.scenictourguide.common.net;

/**
 * describe : 请求方法的枚举类
 * date on 2019/1/26
 * author linghailong
 * email [email protected]
 */
public enum HttpMethod {
    GET,
    POST,
    POST_RAW,
    PUT,
    PUT_RAW,
    DELETE,
    UPLOAD
}

网络层差不多就是这些东西了。
接下来就是请求的过程了。我准备再另写一篇来进行介绍,具体请听下回分解。
