    AndroidUtilCode 强大的工具库

    RxLifecycle 为rxjava而生你懂的

    Gloading 深度解耦Android App中全局加载中、加载失败及空数据视图

    RxJava 不解释

    图片有压缩,可以下载demo apk进行体验
    demo-debug.apk

    安装和依赖

    3种选择

    1、 git clone https://github.com/wobiancao/sugar.git
        implementation project(':sugarlibrary')
        
    2、 implementation 'com.wobiancao:sugarlibrary:{version}'
    
    3、 allprojects {
            repositories {
                ...
                maven { url 'https://jitpack.io' }
            }
        }
    implementation 'com.github.wobiancao:sugar:{version}'
    

    统一配置

    创建DemoConfigure 继承于SugarConfigure 重载相关方法即可:

    public class DemoConfigure extends SugarConfigure {
    
    
        public DemoConfigure(Application application) {
            super(application);
        }
    
        @Override
        public ResponseErrorListener getErrorResponse() {
            return new ResponseErrorListener() {
                @Override
                public void handleResponseError(Context context, Throwable t) {
                    LogUtils.i("捕获异常---" + t.getMessage());
                    ToastUtils.show("发生异常---" + t.getMessage());
                }
            };
        }
    
        @Override
        public int getStatusColor() {
            return R.color.colorPrimary;
        }
    
        @Override
        public AppHttpSetting getHttpSetting() {
            return AppHttpSetting
                    .builder()
                    .with(mApplication)
                    //设置初始的baseUrl host
                    .setBaseUrl(Gank.HOST)
                    //动态修改baseUrl 具体看https://github.com/JessYanCoding/RetrofitUrlManager
                    .putDomain(Wan.DOMAN, Wan.HOST)
                    //是否打印网络请求日志 默认否
                    .setHttpLog(true)
                    //百度Stetho即可 网络监测等 默认否
                    .setHttpMoniter(true)
                    //设置缓存时间 默认60s
                    .setCacheMaxTime(65)
                    //设置连接超时 默认20s
                    .connectTimeout(20)
                    //设置读取超时 默认20s
                    .readTimeout(20)
                    //设置写入超时 默认20s
                    .writeTimeout(20)
                    //请求header
                    .addHeaderInterceptor(getHeader())
                    //添加请求明文公共参数
                    .addCustomHeaderInterceptor(getCustomHeader())
                    //token过期等请求成功处理 一般不需要处理
    //                .addExceptionInterceptor(getExceptionInterceptor())
                    //其它拦截
    //                .addInterceptor(xx)
    //                .addNetworkInterceptor(xxx)
    //                配置自己的缓存
    //                .cache(xx)
                    //甚至另外写一套自己的okhttp builder 也行
    //                .setOkHttpBuilder(xxx)
                    .build();
        }
    
        @Override
        public IToastStyle getToastStyle() {
            return new ToastStyle();
        }
    }
    
    
    • 创建DemoApplication继承于 LibApplication < S extends SugarConfigure > 重写initConfigure()初始化配置即可,详见DemoApplication
    public class DemoApplication extends LibApplication<DemoConfigure> {
    
        @Override
        protected void initConfigure() {
            mConfigure = new DemoConfigure(this);
        }
    
        @Override
        protected void init() {
    
        }
    
    }
    
    

    网络请求统一配置

    • 问题:我们使用RetrofitUrlManager 解决了retorfit动态配置baseUrl的问题,但是每个域名或者说每个接口返回参数封装等的可能不统一(这种情况一般不会出现在公司项目)比如我这个app要展示Gank.ioWanAndroid的界面,这样就是两个网络请求封装,使用sugar可以快速解决此类问题;
    • 使用之前先看源码SugarRepository
    /**
     * @author wobiancao
     * @date 2019/5/20
     * desc :
     */
    public class SugarRepository {
        /**
         * 0 没loading 1 dialog形式  2page形式
         */
        protected final static int LOADING_TYPE_NULL = 0;
        /**
         * 0 没loading 1 dialog形式  2page形式
         */
        protected final static int LOADING_TYPE_DIALOG = 1;
        /**
         * 0 没loading 1 dialog形式  2page形式
         */
        protected final static int LOADING_TYPE_PAGE = 2;
        protected BaseIView mIView;
    
        public SugarRepository(BaseIView IView) {
            mIView = IView;
        }
    
        protected Observable addObservable(Observable observable) {
            if (mIView == null) {
                return null;
            }
            return customObservable(observable);
        }
    
        protected Observable addObservable(Observable observable, int loadingType) {
            if (mIView == null) {
                return null;
            }
            return customObservable(observable)
                    .doOnSubscribe(disposable -> {
                        if (loadingType > 0) {
                            if (loadingType == LOADING_TYPE_DIALOG) {
                                mIView.showDialogLoading();
                            } else {
                                mIView.showLoading();
                            }
                        }
                    });
        }
    
        private Observable customObservable(Observable observable) {
            return observable
                    .compose(mIView.getProvider().bindToLifecycle())
                    .retryWhen(new RetryWithDelay(2, 2))
                    .subscribeOn(Schedulers.io())
                    .subscribeOn(AndroidSchedulers.mainThread())
                    .observeOn(AndroidSchedulers.mainThread())
                    .doFinally(() -> {
                        if (mIView != null) {
                            mIView.hideDialogLoading();
                        }
                    })
                    .doOnNext(o -> {
                        LogUtils.e("doOnNext------" + o);
                        if (mIView != null) {
                            mIView.showLoadSuccess();
                        }
                    })
                    .doOnError(throwable -> {
                        LogUtils.e("doOnError------" + throwable);
                        if (mIView != null) {
                            mIView.showLoadFailed();
                        }
                    });
        }
    }
    
    • addObservable(Observable observable)不会使用任何loading效果,
      addObservable(Observable observable, int loadingType) loadingType : 0 没loading 、1 dialog形式 、2 page形式

    • Repository首先有个契约类,RepositoryContract
      xxxModel为需要增加的一个域名接口,统一配置apiService、请求函数、相应的transformer

    /**
    * @author wobiancao
    * @date 2019-05-21
    * desc :
    */
    public class RepositoryContract {
    
       /**
        * gank.io
        */
       public interface GankModel  {
           Gank getService();
           /**
            * Transformer 需要处理api返回值包装的加上即可
            * @param <T>
            * @return
            */
           <T> ObservableTransformer<GirlsResult<T>, T> gankTransformer();
    
           Observable<List<GirlsData>> getFuliDataRepository(String size, String index);
       }
    
       /**
        * wanandroid
        */
       public interface WanModel{
           Wan getService();
           /**
            * Transformer 需要处理api返回值包装的加上即可
            * @param <T>
            * @return
            */
           <T> ObservableTransformer<WanResult<T>, T> wanTransformer();
    
    
           Observable<WanData> getWanArticleList(String index);
       }
    }
    
    /**
    * @author wobiancao
    * @date 2019/5/20
    * desc :
    */
    public class GankRepository extends SugarRepository implements RepositoryContract.GankModel {
    
    
       public GankRepository(BaseIView IView) {
           super(IView);
       }
    
       @Override
       public Gank getService() {
           return AppHttpClient.getInstance().initService(Gank.class);
       }
    
    
       @Override
       public <T> ObservableTransformer<GirlsResult<T>, T> gankTransformer() {
    
           return upstream -> upstream
                   .flatMap((Function<GirlsResult<T>, ObservableSource<T>>) tGirlsResult -> {
                       if (tGirlsResult == null) {
                           return Observable.error(new HttpException("返回值为null"));
                       }
                       if (!tGirlsResult.error) {
                           return Observable.just(tGirlsResult.results);
                       } else {
                           return Observable.error(new HttpException("接口异常"));
                       }
                   });
    
       }
    
       @Override
       public Observable<List<GirlsData>> getFuliDataRepository(String size, String index) {
           return addObservable(getService()
                   .getFuliData(size, index)
                   .compose(gankTransformer()), LOADING_TYPE_PAGE);
       }
    
    }
    
    

    最后mvp创建(之后会写相应的Template

    image
    • =。=假的,接下来看代码

    WanContract

    /**
     * @author wobiancao
     * @date 2019-05-21
     * desc :
     */
    public class WanContract {
        public interface PView{
    
            void getWanArticleList(String index);
        }
    
        public interface IView extends BaseIView {
            /**
             * 绑定列表数据
             * @param data
             */
            void bindData(WanData data);
        }
    }
    

    WanPresenter

    
    /**
     * @author wobiancao
     * @date 2019-05-21
     * desc :
     */
    public class WanPresenter extends BasePresenter<WanContract.IView, WanRepository> implements WanContract.PView {
    
        @Override
        protected void initRepository() {
            mModel = new WanRepository(mView);
        }
    
        @Override
        public void getWanArticleList(String index) {
            mModel.getWanArticleList(index)
                    .subscribe(new ErrorHandleSubscriber<WanData>(rxErrorHandler) {
                        @Override
                        public void onNext(WanData wanData) {
                            mView.bindData(wanData);
                        }
    
                    });
        }
    
    
    }
    
    
    • 就是这么简单,最后就是在view层如何使用了,老规矩先看代码WanActivity
    /**
     * @author wobiancao
     * @date 2019-05-21
     * desc :
     */
    @CreatePresenter(presenter = WanPresenter.class)
    public class WanActivity extends BaseActivity<WanPresenter> implements WanContract.IView {
        @PresenterVariable
        WanPresenter mPresenter;
        TextView mInfoView;
        Toolbar mToolbar;
        @Override
        protected int getContentView() {
            return R.layout.gank_activity_list;
        }
    
        @Override
        public void init(Bundle savedInstanceState) {
            mInfoView = findViewById(R.id.tv_info);
            mToolbar = findViewById(R.id.toolbar);
            setSupportActionBar(mToolbar);
            ActionBar actionBar = getSupportActionBar();
            if (actionBar != null) {
                actionBar.setDisplayHomeAsUpEnabled(true);
                actionBar.setTitle("WanAndroid");
            }
        }
    
        @Override
        public void loadData() {
            mPresenter.getWanArticleList("1");
        }
    
        @Override
        public void bindData(WanData data) {
            String jsonStr = new Gson().toJson(data);
            mInfoView.setText(jsonStr);
        }
    
        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            int id = item.getItemId();
            switch (id) {
                case android.R.id.home:
                    finish();
                    break;
            }
            return super.onOptionsItemSelected(item);
        }
    }
    

    是的Presenter创建只需要注解即可,并且支持多个presenter

    这里要万分感谢EasyMvp一个简单强大且灵活的MVP框架

    • 首先,单个presenter
    @CreatePresenter(presenter = WanPresenter.class)
    public class WanActivity extends BaseActivity<WanPresenter> implements WanContract.IView 
    

    获取presenter变量两种方式

    1、通过注解

    @PresenterVariable
    WanPresenter mPresenter;
    

    2、通过getPresenter()函数

    xxActivity extends BaseActivity<xxPresenter>...
    
    xxPresenter getPresenter()
    
    • 多个prenenter
      就只有通过注解获得变量了
    @CreatePresenter(presenter = {xxPresenter1.class, xxPresenter2.class})
    xxActivity extends BaseActivity...
    
    @PresenterVariable
    xxPresenter1 mPresenter1;
    
    @PresenterVariable
    xxPresenter2 mPresenter2;
