rxAndroid+OkHttp+retrofit2三贱客

   研究了好久的上述三个框架，一开始都是在看文档，看api，看博客，但是收效甚微。“实践才是检验真理的唯一标注”，动手写下才发现，更容易理解

   这里是第一个版本的实现方法，以后会后续更新：

1.    首先是进行依赖：

   compile 'com.android.support:appcompat-v7:24.1.1'
       compile 'com.android.support:support-v4:24.1.1'
       compile 'com.android.support:recyclerview-v7:24.1.1'
       compile 'com.android.support:cardview-v7:24.1.1'
       compile 'com.android.support:design:24.1.1'
   
       compile 'com.squareup.okhttp3:okhttp:3.2.0'
       compile 'com.squareup.retrofit2:retrofit:2.0.0'
       compile 'com.squareup.retrofit2:converter-gson:2.0.0'
       compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0'
       compile 'com.github.bumptech.glide:glide:3.7.0'
       compile 'com.jakewharton:butterknife:7.0.1'
       compile 'io.reactivex:rxjava:1.1.0'
       compile 'io.reactivex:rxandroid:1.1.0'
       compile 'com.jakewharton.rxbinding:rxbinding:0.4.0'
       compile 'io.reactivex:rxjava:1.0.10'
       compile 'com.github.bumptech.glide:glide:3.6.0'

   
   
2. 项目结构如下：
3. 其中测试的api包下的mainapi 的interface如下

   /**
    * Created by Ly on 2016/8/10.
    */
   public interface mainFragmentApi {
       @GET("xxxxxAction!getHotContent.htm")
       Observable<L_MainContentBean> search(@Query("infoType") String infoType);
   
       @GET("xxxxxxx!getInformationType.htm")
       Observable<L_MainTitleBean> getMainTitle();
   }
   

   
   
4. 封装的NetWord工具类代码如下

   package com.Lht.RxAndroidSample.business.network;
   
   import com.Lht.RxAndroidSample.business.network.api.mainFragmentApi;
   
   import okhttp3.OkHttpClient;
   import retrofit2.CallAdapter;
   import retrofit2.Converter;
   import retrofit2.Retrofit;
   import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory;
   import retrofit2.converter.gson.GsonConverterFactory;
   
   /**
    * Created by Ly on 2016/8/10.
    */
   public class Network {
       private static final String BASE_URL = "http://app.xxxxxxxx.com.cn";
       private static final String BASE_PIC = "http://web.xxxxxxx.com.cn/";
   
   
       // 主页的fragment
       private static mainFragmentApi mMainContentApi;
   
       /**
        * 初始化必须的工具类
        */
       private static OkHttpClient okHttpClient = new OkHttpClient();
       private static Converter.Factory gsonConverterFactory = GsonConverterFactory.create();
       private static CallAdapter.Factory rxJavaCallAdapterFactory = RxJavaCallAdapterFactory.create();
   
   
       public static String getBasePic() {
           return BASE_PIC;
       }
   
   
       /**
        * 获取首页内容
        *
        * @return
        */
       public static mainFragmentApi dogetMainFragmentApi() {
           if (mMainContentApi == null) {
               Retrofit retrofit = new Retrofit.Builder()
                       .client(okHttpClient)
                       .baseUrl(BASE_URL)
                       .addConverterFactory(gsonConverterFactory)
                       .addCallAdapterFactory(rxJavaCallAdapterFactory)
                       .build();
               mMainContentApi = retrofit.create(mainFragmentApi.class);
           }
           return mMainContentApi;
       }
   }
   

   
   
5. 看到这里是不是懵逼了？我也是，实操才是学习的最好办法，调用方法如下

   package com.Lht.RxAndroidSample.business.fragment.main;
   
   import android.os.Bundle;
   import android.support.annotation.Nullable;
   import android.support.design.widget.TabLayout;
   import android.support.v4.app.Fragment;
   import android.support.v4.app.FragmentManager;
   import android.support.v4.app.FragmentPagerAdapter;
   import android.support.v4.view.ViewPager;
   import android.util.Log;
   import android.view.LayoutInflater;
   import android.view.View;
   import android.view.ViewGroup;
   import android.widget.Toast;
   
   import com.Lht.RxAndroidSample.R;
   import com.Lht.RxAndroidSample.business.base.baseFragment;
   import com.Lht.RxAndroidSample.business.fragment.main.detailfragment.L_MainChildFragment;
   import com.Lht.RxAndroidSample.business.network.Network;
   import com.Lht.RxAndroidSample.module.bean.L_MainTitleBean;
   
   import java.util.ArrayList;
   import java.util.List;
   
   import butterknife.Bind;
   import rx.Observer;
   import rx.android.schedulers.AndroidSchedulers;
   import rx.schedulers.Schedulers;
   
   /**
    * Created by Ly on 2016/8/9.
    */
   public class MainFragment extends baseFragment {
       @Bind(android.R.id.tabs)
       TabLayout tbMainPagerTabLayout;
       @Bind(R.id.viewPager)
       ViewPager vpMainPagerViewPager;
   
   
       private mainAdapter mMainAdapter;
   
       @Nullable
       @Override
       public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
           return inflater.inflate(R.layout.l_fragment_mainpager, container, false);
       }
   
       @Override
       public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
           super.onViewCreated(view, savedInstanceState);
           tbMainPagerTabLayout.setupWithViewPager(vpMainPagerViewPager);
           tbMainPagerTabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
               @Override
               public void onTabSelected(TabLayout.Tab tab) {
                   if (mMainAdapter.getCount() > 0 && mMainAdapter.getCount() > tab.getPosition()) {
                       ((L_MainChildFragment) mMainAdapter.getItem(tab.getPosition())).doLoadData(mMainAdapter.getTypeid(tab.getPosition()));
                   }
               }
   
               @Override
               public void onTabUnselected(TabLayout.Tab tab) {
   
               }
   
               @Override
               public void onTabReselected(TabLayout.Tab tab) {
   
               }
           });
           subscription = Network
                   .dogetMainFragmentApi()
                   .getMainTitle()
                   .subscribeOn(Schedulers.io())
                   .observeOn(AndroidSchedulers.mainThread())
                   .subscribe(mainTitleBeanObservable);
       }
   
       /**
        * 获取头部信息的观察者
        */
       Observer<L_MainTitleBean> mainTitleBeanObservable = new Observer<L_MainTitleBean>() {
           @Override
           public void onCompleted() {
   
           }
   
           @Override
           public void onError(Throwable e) {
               Toast.makeText(getActivity(), e.getMessage(), Toast.LENGTH_SHORT).show();
           }
   
           @Override
           public void onNext(L_MainTitleBean lMainTitleBean) {
               Log.e("LHT", lMainTitleBean.toString());
               if (lMainTitleBean.getCode() == 0) {
                   mMainAdapter = new mainAdapter(getChildFragmentManager(), lMainTitleBean.getInfoTypeVoList());
                   vpMainPagerViewPager.setAdapter(mMainAdapter);
                   vpMainPagerViewPager.setOffscreenPageLimit(lMainTitleBean.getInfoTypeVoList().size() - 1);
               } else {
                   Toast.makeText(getActivity(), "加载失败", Toast.LENGTH_SHORT).show();
               }
           }
       };
   
       /**
        * 首页的适配器
        */
       private class mainAdapter extends FragmentPagerAdapter {
           private List<L_MainTitleBean.InfoTypeVoListBean> listBeen = new ArrayList<>();
           private List<Fragment> fragmentList = new ArrayList<>();
   
           public mainAdapter(FragmentManager fm, List<L_MainTitleBean.InfoTypeVoListBean> listBeen) {
               super(fm);
               this.listBeen = listBeen;
               for (int i = 0; i < this.listBeen.size(); i++) {
                   fragmentList.add(new L_MainChildFragment());
               }
           }
   
           @Override
           public Fragment getItem(int position) {
               return fragmentList.get(position);
           }
   
           public String getTypeid(int postion) {
               return listBeen.get(postion).getTypeId();
           }
   
           @Override
           public int getCount() {

           }
   
           @Override
           public CharSequence getPageTitle(int position) {
               return listBeen.get(position).getName();
           }
       }
   }
   
   
   

   
   
6. 我知道还是很懵逼，但是这个急不来，慢慢看，毕竟是多个工具类一起嵌套apk下载地址
