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：

• 网络配置(Retrofit和okhttp3)Retrofit请求，rxbus等）
• 状态栏默认颜色ImmersionBar
• toast样式ToastUtils你可以不用设置，有默认的
• RxErroHandler rxjava异常获取
• 网络设置直接见代码即可，跟retrofit一样的配置,写了一些默认的拦截器可继承后使用也可自己写,host可以动态配置RetrofitUrlManager
• 解耦页面状态切换Gloading 你可以不用设置，有默认的
• 默认等待框BaseLoadingDialog你可以不用设置，有默认的
• 更多详见AppConfigureDelegate

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.io和WanAndroid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);
   }
}

• 使用，如GankRepository

/**
* @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）

• 以WanActivity举例
• 构成为 WanContract契约、WanPresenter
  好了，完了，结束。

• =。=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;
