TouTiao开源项目 分析笔记12 从总体到局部 构建视频主页面

1.构建视频主列表的整体碎片VideoTabLayout

1.1.首先创建一个VideoTabLayout　

package com.jasonjan.headnews.module.video;

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.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.jasonjan.headnews.R;
import com.jasonjan.headnews.global.InitApp;
import com.jasonjan.headnews.adapter.BasePagerAdapter;
import com.jasonjan.headnews.test.Test_Fragment;
import com.jasonjan.headnews.util.SettingUtil;

import java.util.ArrayList;
import java.util.List;

public class VideoTabLayout extends Fragment {
    private static VideoTabLayout instance = null;
    private static int pageSize = InitApp.AppContext.getResources().getStringArray(R.array.mobile_video_id).length;
    private String categoryId[] = InitApp.AppContext.getResources().getStringArray(R.array.mobile_video_id);
    private String categoryName[] = InitApp.AppContext.getResources().getStringArray(R.array.mobile_video_name);
    private TabLayout tabLayout;
    private ViewPager viewPager;
    private List<Fragment> fragmentList = new ArrayList<>();
    private BasePagerAdapter adapter;

    public static VideoTabLayout getInstance() {
        if (instance == null) {
            instance = new VideoTabLayout();
        }
        return instance;
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_video_tab, container, false);
        initView(view);
        initData();
        return view;
    }

    @Override
    public void onResume() {
        super.onResume();
        tabLayout.setBackgroundColor(SettingUtil.getInstance().getColor());
    }

    private void initView(View view) {
        tabLayout = view.findViewById(R.id.tab_layout_video);
        viewPager = view.findViewById(R.id.view_pager_video);

        tabLayout.setupWithViewPager(viewPager);
        tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
        tabLayout.setBackgroundColor(SettingUtil.getInstance().getColor());
        viewPager.setOffscreenPageLimit(pageSize);
    }

    private void initData() {
        for (int i = 0; i < categoryId.length; i++) {
            Fragment fragment = VideoArticleView.newInstance(categoryId[i]);
            fragmentList.add(fragment);
        }
        adapter = new BasePagerAdapter(getChildFragmentManager(), fragmentList, categoryName);
        viewPager.setAdapter(adapter);
    }

    @Override
    public void onDestroy() {
        if (instance != null) {
            instance = null;
        }
        super.onDestroy();
    }
}

　　这里先声明视频中的小碎片名称为：VideoArticleView。

　　后面详细分析这个Fragment。主要就是视频的一些小分类。用的是同一种布局方式。

1.2.这个片段需要一个布局fragment_video_tab.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout_video"
        style="@style/TabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:theme="@style/AppTheme.AppBarOverlay"
        app:tabTextColor="@color/gray">
    </android.support.design.widget.TabLayout>

    <android.support.v4.view.ViewPager
        android:id="@+id/view_pager_video"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:layout="@layout/fragment_list">
    </android.support.v4.view.ViewPager>

</LinearLayout>

1.3.布局真实效果预览

　　

1.4.然后就是上方tablayout中的静态文字

　　在资源文件中values中的mobile_video_category.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string-array name="mobile_video_name">
        <item>推荐</item>
        <item>音乐</item>
        <item>搞笑</item>
        <item>社会</item>
        <item>小品</item>

        <item>生活</item>
        <item>影视</item>
        <item>娱乐</item>
        <item>呆萌</item>
        <item>游戏</item>

        <item>原创</item>
        <item>开眼</item>

    </string-array>

    <string-array name="mobile_video_id">
        <item>video</item>
        <item>subv_voice</item>
        <item>subv_funny</item>
        <item>subv_society</item>
        <item>subv_comedy</item>

        <item>subv_life</item>
        <item>subv_movie</item>
        <item>subv_entertainment</item>
        <item>subv_cute</item>
        <item>subv_game</item>

        <item>subv_boutique</item>
        <item>subv_broaden_view</item>

    </string-array>

</resources>

1.5.然后就是将视频主列表的十二种类型用一个BasePagerAdapter联系起来

　　下面的代码在上方的VideoTabLayout.java中的一个函数中，这里再重复拿出来讲一下。

 private void initData() {
        for (int i = 0; i < categoryId.length; i++) {
            Fragment fragment = VideoArticleView.newInstance(categoryId[i]);
            fragmentList.add(fragment);
        }
        adapter = new BasePagerAdapter(getChildFragmentManager(), fragmentList, categoryName);
        viewPager.setAdapter(adapter);
    }

　　

1.6.看一下集合所有分类的碎片的适配器==>BasePagerAdapter　

public class BasePagerAdapter extends FragmentStatePagerAdapter {

    private List<Fragment> fragmentList;
    private List<String> titleList;

    public BasePagerAdapter(FragmentManager fm, List<Fragment> fragmentList, String[] titles) {
        super(fm);
        this.fragmentList = fragmentList;
        this.titleList = new ArrayList<>(Arrays.asList(titles));
    }

    public BasePagerAdapter(FragmentManager fm, List<Fragment> fragmentList, List<String> titleList) {
        super(fm);
        this.fragmentList = fragmentList;
        this.titleList = titleList;
    }

    @Override
    public Fragment getItem(int position) {
        return fragmentList.get(position);
    }

    @Override
    public int getCount() {
        return titleList.size();
    }

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

    @Override
    public int getItemPosition(Object object) {
        return PagerAdapter.POSITION_NONE;
    }

    public void recreateItems(List<Fragment> fragmentList, List<String> titleList) {
        this.fragmentList = fragmentList;
        this.titleList = titleList;
        notifyDataSetChanged();
    }
}

1.7.第一阶段结束，主要完成了VideoTabLayout这个视频主页面和相应的逻辑。

　　第二阶段主要处理12个分片段的布局和逻辑了。

2.视频系列的文章的基础Bean类

2.1.第一集团数据返回==>调用API后返回的数据（包括很多杂项）

　　这个类比较庞大，都是按照服务器返回的数据而对应建立的。 

3.视频系列的视图以及处理器控制

3.1.最底层视图以及处理器接口

public interface IVideoArticle {

    interface View extends IBaseListView<Presenter> {

        /**
         * 请求数据
         */
        void onLoadData();
    }

    interface Presenter extends IBasePresenter {

        /**
         * 请求数据
         */
        void doLoadData(String... category);

        /**
         * 再起请求数据
         */
        void doLoadMoreData();

        /**
         * 设置适配器
         */
        void doSetAdapter(List<MultiNewsArticleDataBean> dataBeen);
    }
}

3.2.视频系列的视图

package com.jasonjan.headnews.module.video;

import android.os.Bundle;
import android.view.View;

import com.jasonjan.headnews.adapter.DiffCallback;
import com.jasonjan.headnews.bean.common.LoadingBean;
import com.jasonjan.headnews.main.Register;
import com.jasonjan.headnews.module.base.BaseListFragment;
import com.jasonjan.headnews.util.OnLoadMoreListener;

import java.util.List;

import me.drakeet.multitype.Items;
import me.drakeet.multitype.MultiTypeAdapter;

/**
 * Created by JasonJan on 2017/12/14.
 */

public class VideoArticleView extends BaseListFragment<IVideoArticle.Presenter> implements IVideoArticle.View {
    private static final String TAG="VideoArticleView";
    private String categoryId;

    public static VideoArticleView newInstance(String categoryId){
        Bundle bundle=new Bundle();
        bundle.putString(TAG,categoryId);
        VideoArticleView videoArticleView=new VideoArticleView();
        videoArticleView.setArguments(bundle);
        return videoArticleView;
    }

    @Override
    protected void initData() {
        categoryId = getArguments().getString(TAG);
    }

    @Override
    protected void initView(View view){
        super.initView(view);
        super.initView(view);
        adapter = new MultiTypeAdapter(oldItems);
        Register.registerVideoArticleItem(adapter);
        recyclerView.setAdapter(adapter);
        recyclerView.addOnScrollListener(new OnLoadMoreListener() {
            @Override
            public void onLoadMore() {
                if (canLoadMore) {
                    canLoadMore = false;
                    presenter.doLoadMoreData();
                }
            }
        });
    }

    @Override
    public void fetchData() {
        super.fetchData();
        onLoadData();
    }

    @Override
    public void onLoadData() {
        onShowLoading();
        presenter.doLoadData(categoryId);
    }

    @Override
    public void onSetAdapter(final List<?> list) {
        Items newItems = new Items(list);
        newItems.add(new LoadingBean());
        DiffCallback.notifyDataSetChanged(oldItems, newItems, DiffCallback.MUlTI_NEWS, adapter);
        oldItems.clear();
        oldItems.addAll(newItems);
        canLoadMore = true;
    }

    /**
     * API 跟新闻的一样 所以采用类似新闻的 presenter
     *
     * @param presenter
     */
    @Override
    public void setPresenter(IVideoArticle.Presenter presenter) {
        if (null == presenter) {
            this.presenter = new VideoArticlePresenter(this);
        }
    }
}

　　然后发现处理器还没有设置呢。

　　然后还有视图绑定也未实现（在自定义的Register中实现）

　　然后还有处理新老数据来刷新（在自定义的Diffback中实现）

3.3.视频系列的处理器

　　这个处理器可以就用新闻页面通用的一个处理器

　　不过我还是自己另外写了一个处理器

　　和新闻页面的处理器非常相似。

3.4.视频系列文章的API请求

public interface IMobileVideoApi {

    /**
     * 获取视频标题等信息
     * http://is.snssdk.com/api/news/feed/v53/?category=subv_cute&refer=1&count=20&max_behot_time=1499321562&iid=11776029171&device_id=36394312781
     */
    @GET("http://is.snssdk.com/api/news/feed/v62/?iid=5034850950&device_id=6096495334&refer=1&count=20&aid=13")
    Observable<MultiNewsArticleBean> getVideoArticle(
            @Query("category") String category,
            @Query("max_behot_time") String maxBehotTime);

    /**
     * 获取视频信息
     * Api 生成较复杂 详情查看 
     * http://ib.365yg.com/video/urls/v/1/toutiao/mp4/视频ID?r=17位随机数&s=加密结果
     */
    @GET
    Observable<VideoContentBean> getVideoContent(@Url String url);
}

　　可以看到，请求视频的地址和请求之前新闻的网址是一样的

　　而且返回数据也一样==>Observable<MultiNewsArticleBean>

　　当然唯一不同的应该就是这个category，

　　如果带了这个参数，我猜想应该返回的东西都有带有视频的图片。

3.5.然后在Register类中注入数据类型　

/**
     * 注入视频类型
     * @param adapter
     */
    public static void registerVideoArticleItem(@NonNull MultiTypeAdapter adapter) {
        adapter.register(MultiNewsArticleDataBean.class, new NewsArticleVideoViewBinder());
        adapter.register(LoadingBean.class, new LoadingViewBinder());
        adapter.register(LoadingEndBean.class, new LoadingEndViewBinder());
    }

3.6.最后再DiffCallback中加视频类型

　　在areItemsTheSame函数中添加Video类型。

　　因为类型和Multi_News一样，用这个代替也一样。

case MUlTI_NEWS:
                    return ((MultiNewsArticleDataBean) oldList.get(oldItemPosition)).getTitle().equals(
                            ((MultiNewsArticleDataBean) newList.get(newItemPosition)).getTitle());

　　在areContentsTheSame中添加这个类型。

case MUlTI_NEWS:
                    return ((MultiNewsArticleDataBean) oldList.get(oldItemPosition)).getItem_id() ==
                            ((MultiNewsArticleDataBean) newList.get(newItemPosition)).getItem_id();

4.视图绑定类

4.1.视图绑定类的布局定义==>item_news_article_video.xml

　　这个绑定类和新闻中的页面的其中一种类型完全一样。

　　因为新闻页面中有3种类型，一种纯文字，一种图片，一种视频。

　　这里就直接用新闻中的视频的绑定类即可。

　　因为API也是用的新闻

　　可以说视频这个大类，就是从新闻中筛选出的视频类型。

　　通过传入的一个参数category，返回的全是视频。

5.目前效果预览

5.1.目前完成的工作

　　新闻的三种大类型

　　图片的一种大类型，这种大类型有4个分类，为全部、老照片、故事照片和摄影集。

　　视频采用的是新闻中的其中一种大类型，所以直接用新闻中的绑定类即可，API也一样的。

　　但是每种类型的评论以及详细页面还未实现。
