#Retrofit 使用

[Retrofit 2.0 + OkHttp 3.0 配置](https://drakeet.me/retrofit-2-0-okhttp-3-0-config)

##转换器

[retrofit](http://square.github.io/retrofit/#restadapter-configuration)
[RxAndroid+Retrofit环境搭建](http://www.07net01.com/program/2016/02/1280821.html)

转换器可以被添加到支持其他类型。六兄弟模块适应流行的序列化库为您提供方便。
Converters can be added to support other types. Six sibling modules adapt popular serialization libraries for your convenience.

	Gson: com.squareup.retrofit2:converter-gson
	Jackson: com.squareup.retrofit2:converter-jackson
	Moshi: com.squareup.retrofit2:converter-moshi
	Protobuf: com.squareup.retrofit2:converter-protobuf
	Wire: com.squareup.retrofit2:converter-wire
	Simple XML: com.squareup.retrofit2:converter-simplexml
	Scalars (primitives, boxed, and String): com.squareup.retrofit2:converter-scalars

直接返回String类型需引入：ScalarsConverterFactory.create()

	retrofit = new Retrofit.Builder()
			.client(MyOkHttpClient.getMyOkHttpClient().getOkHttpClient())//设置不同的底层网络库
			.baseUrl(strBaseUrl)
			.addConverterFactory(ScalarsConverterFactory.create())//添加 String类型[ Scalars (primitives, boxed, and String)] 转换器
			.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
			.build();
			
返回Gson类型需引入：GsonConverterFactory.create()

	retrofit = new Retrofit.Builder()
			.client(MyOkHttpClient.getMyOkHttpClient().getOkHttpClient())//设置不同的底层网络库
			.baseUrl(strBaseUrl)
			.addConverterFactory(GsonConverterFactory.create())//添加 json 转换器
			.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
			.build();

##Retrofit 结合 RxJava使用

[Retrofit 结合 RxJava使用](http://blog.csdn.net/ttccaaa/article/details/50659234)

 1. 添加依赖
		
		compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'
		compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'
		
		compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'
		
		compile 'io.reactivex:rxandroid:1.1.0'
		compile 'io.reactivex:rxjava:1.1.0'
		
	前两个是 Retrofit 和 Gson 的依赖，第三个是 Retrofit 中 RxJava 转换器的依赖，最后两个就是 RxJava 和 Rx Android 的依赖

 2. 编写 API

	使用 RxJava 的情况下，接口文件稍有修改，接口中的方法的返回类型不再是 Call 而是 Observable 类型：
		
		public interface GitHub {
		
		    @GET("/repos/{owner}/{repo}/contributors")
		    Call<List<Contributor>> contributors(@Path("owner") String owner,@Path("repo") String repo);
		
		    //使用 RxJava 的方法,返回一个 Observable
		    @GET("/repos/{owner}/{repo}/contributors")
		    Observable<List<Contributor>> RxContributors(@Path("owner") String owner,@Path("repo") String repo);
		}

	结合 RxJava 使用的 接口就定义好了，模型类不需要变动，接下来直接进行网络请求

 3. 网络请求

	使用 RxJava 的 Retrofit 可以直接在 主线程中编写。
		
		@Override
		protected void onCreate(Bundle savedInstanceState) {
		    super.onCreate(savedInstanceState);
		    setContentView(R.layout.activity_main);
		
		    Retrofit retrofit=new Retrofit.Builder()
		            .baseUrl("https://api.github.com")
		            .addConverterFactory(GsonConverterFactory.create())//添加 json 转换器
		            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
		            .build();
		
		    GitHub gitHub=retrofit.create(GitHub.class);
		    gitHub.RxContributors("square","retrofit")
		            .subscribeOn(Schedulers.io())
		            .observeOn(AndroidSchedulers.mainThread())
		            .subscribe(new Subscriber<List<Contributor>>() {
		                @Override
		                public void onCompleted() {
		                    Log.i("TAG","onCompleted");
		                }
		
		                @Override
		                public void onError(Throwable e) {
		
		                }
		
		                @Override
		                public void onNext(List<Contributor> contributors) {
		                   for (Contributor c:contributors){
		                       Log.i("TAG","RxJava-->"+c.getLogin()+"  "+c.getId()+"  "+c.getContributions());
		                   }
		                }
		            });
		}

##使用Retrofit和Okhttp实现网络缓存。无网读缓存，有网根据过期时间重新请求

[okhttp 请求设置官方文档](https://github.com/square/okhttp/wiki/Recipes)
[使用Retrofit和Okhttp实现网络缓存。无网读缓存，有网根据过期时间重新请求](http://www.jianshu.com/p/9c3b4ea108a7#)
[OuNews 新闻：RetrofitManager类下的 initOkHttpClient 方法](https://github.com/oubowu/OuNews)
 okhttp3.X，retrofit:2.0.0-beta4适用

 1. 配置okhttp中的Cache
 
		OkHttpClient okHttpClient;
		File cacheFile = new File(DemoActivity.this.getCacheDir(), "[缓存目录]");
		Cache cache = new Cache(cacheFile, 1024 * 1024 * 10); //100Mb
		okHttpClient = new OkHttpClient.Builder()
		     .cache(cache)
		     .build();
		
	栗子：
	
		// 完成缓存
		public class MyOkHttpClient {
		
		    //设缓存有效期为两天
		    protected static final long CACHE_STALE_SEC = 60 * 60 * 24 * 2;
		    //查询缓存的Cache-Control设置，为if-only-cache时只查询缓存而不会请求服务器，max-stale可以配合设置缓存失效时间
		    protected static final String CACHE_CONTROL_CACHE = "only-if-cached, max-stale=" + CACHE_STALE_SEC;
		    //查询网络的Cache-Control设置，头部Cache-Control设为max-age=0时则不会使用缓存而请求服务器
		    protected static final String CACHE_CONTROL_NETWORK = "max-age=0";
		
		    private String TAG = "MyOkHttpClient";
		
		    private OkHttpClient okHttpClient;
		    private static MyOkHttpClient myOkHttpClient;
		
		    public static MyOkHttpClient getMyOkHttpClient() {
		        if (myOkHttpClient == null) {
		            myOkHttpClient = new MyOkHttpClient();
		
		        }
		
		        return myOkHttpClient;
		    }
		
		    /**
		     * 初始化
		     *
		     * @param mContext
		     */
		    public void init(final Context mContext) {
		
		        if (okHttpClient != null) {
		            return;
		        }
		
		
		        Log.e(TAG, "初始化okHttpClient");
		        // 因为BaseUrl不同所以这里Retrofit不为静态，但是OkHttpClient配置是一样的,静态创建一次即可
		        File cacheFile = new File(
		                mContext.getCacheDir(),
		                "HttpCache"
		        ); // 指定缓存路径
		        Cache cache = new Cache(cacheFile, 1024 * 1024 * 100); // 指定缓存大小100Mb
		        // 云端响应头拦截器，用来配置缓存策略
		        Interceptor rewriteCacheControlInterceptor = new Interceptor() {
		            @Override
		            public Response intercept(Chain chain) throws IOException {
		                Request request = chain.request();
		                if (!NetUtil.isConnected(mContext)) {
		                    request = request.newBuilder()
		                            .cacheControl(CacheControl.FORCE_CACHE).build();
		                    Log.e(TAG, "no network");
		                }
		                Response originalResponse = chain.proceed(request);
		                if (NetUtil.isConnected(mContext)) {
		                    //有网的时候读接口上的@Headers里的配置，你可以在这里进行统一的设置
		                    String cacheControl = request.cacheControl().toString();
		                    return originalResponse.newBuilder()
		                            .header("Cache-Control", cacheControl)
		                            .removeHeader("Pragma").build();
		                } else {
		                    return originalResponse.newBuilder().header("Cache-Control",
		                            "public, only-if-cached," + CACHE_STALE_SEC)
		                            .removeHeader("Pragma").build();
		                }
		            }
		        };
		        okHttpClient = new OkHttpClient.Builder().cache(cache)
		                .addNetworkInterceptor(rewriteCacheControlInterceptor)
		                .addInterceptor(rewriteCacheControlInterceptor)
		                .connectTimeout(30, TimeUnit.SECONDS).build();
		
		    }
		
		    public OkHttpClient getOkHttpClient() {
		        return okHttpClient;
		    }
		
		    /**
		     * 根据网络状况获取缓存的策略
		     *
		     * @return
		     */
		    @NonNull
		    public static String getCacheControl(Context mContext) {
		        return NetUtil.isConnected(mContext) ? CACHE_CONTROL_NETWORK : CACHE_CONTROL_CACHE;
		    }
		
		}


 2. 配置请求头中的cache-control
	
	    //使用 RxJava 的方法,返回一个 Observable
	    @Headers("Cache-Control: public, max-age=3600")
	    @GET("/repos/{owner}/{repo}/contributors")
	    Observable<List<Contributor>> RxContributors(@Path("owner") String owner,@Path("repo") String repo);

 3. 配置请求 Retrofit 设置不同的底层网络库

        Retrofit retrofit = new Retrofit.Builder()
                .client(okHttpClient)
                .baseUrl("https://api.github.com")
                .addConverterFactory(GsonConverterFactory.create())//添加 json 转换器
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
                .build();

 - [Retrofit error URL query string must not have replace block](http://stackoverflow.com/questions/24610243/retrofit-error-url-query-string-must-not-have-replace-block)

## 其他笔记

@Path:路径

@Query:查询条件，如：     

	xx=yy

如果有多个查询条件可以使用: ` @QueryMap ` ;

### CoordinatorLayout

 - [Android 组件属性](http://blog.csdn.net/mg505/article/details/7714658)
 
 总结： 为了使得Toolbar有滑动效果，必须做到如下三点：
 
 注：CoordinatorLayout如果是最外的布局要去掉：
 
	
 
 1、CoordinatorLayout必须作为整个布局的父布局容器。
 2、 给需要滑动的组件设置 app:layout_scrollFlags=”scroll|enterAlways” 属性。
 3、给你的可滑动的组件，也就是RecyclerView 或者 NestedScrollView 设置如下属性：
 
	app:layout_behavior="@string/appbar_scrolling_view_behavior"

## 上下拉监听

`SwipeRefreshLayout.OnRefreshListener` 下拉监听

`RecyclerView.OnScrollListener` 到底监听    

[Android一点 RecyclerView上拉刷新](http://blog.csdn.net/qqqgl/article/details/50353642)
	
	recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
	            @Override
	            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
	                super.onScrollStateChanged(recyclerView, newState);
	                if (newState == RecyclerView.SCROLL_STATE_IDLE) {
	                    onListScrolled();
	                }
	            }
	        });
	        
## RecyclerView多Item的情况

[RecyclerView多Item的情况](http://ju.outofmemory.cn/entry/185097)

	其中 getItemViewType 用来返回当前项是哪种类型布局， getViewTypeCount 返回当前ListView总共多少种类型的布局
	
	如果在 RecyclerView 实现多种Item，只需要实现一个 getItemType 方法，用来返回item的种类 
	在 onCreateViewHolder 和 onBindViewHolder 方法中，第二个参数就是item的类型

原因：

    在2.0版本的新功能已添加即时运行。
    要启用此功能的工具添加了大量的元信息，所以第一个构建和上传需要更多的时间。
    请注意有关设置的minSdkVersion 15或更高，以获得任何盈利。

    In version 2.0 a new feature was added instant-run.

    To enable this feature tool adds a lots of meta information, so the first build and upload takes more time.

    Be aware about setting minSdkVersion 15 or higher to get any profit.

解决步骤：

    1、点击：Settings → Build, Execution, Deployment → Instant Run
    2、取消选择：Enable Instant Run to hot swap code/resoure changes on deploy

这样会取消功能``` 即时运行 ```，但可以解决这个问题。

# 增加分组的Adapter：BaseTypeItemQuickAdapter

主要还是BaseQuickAdapter为样本，重写``` getItemViewType ```，主要修改如下：


    /**
     * 返回的布局判断
     * @param position
     * @return
     */
    @Override
    public int getItemViewType(int position) {

        if (position == 0 || oldCount == position) {
            return TYPE_TITLE;
        } else {
            return TYPE_ITEM;
        }

    }

    /**
     * 对不同类型的操作
     * @param viewGroup
     * @param viewType
     * @return
     */
    @Override
    public BaseAdapterHelper onCreateViewHolder(ViewGroup viewGroup, int viewType) {
        View view = null;

        switch (viewType) {
            case TYPE_TITLE:

                view = LayoutInflater.from(viewGroup.getContext()).inflate(titleLayoutResId, viewGroup, false);

                break;
            case TYPE_ITEM:
                view = LayoutInflater.from(viewGroup.getContext()).inflate(itemLayoutResId, viewGroup, false);

                break;
        }

        if (view == null) {
            return null;
        }

        view.setOnClickListener(this);
        BaseAdapterHelper vh = new BaseAdapterHelper(view);
        return vh;
    }
