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; /** * Created by JasonJan on 2017/12/1. */ 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。
package com.jasonjan.headnews.module.video; import android.text.TextUtils; import com.google.gson.Gson; import com.jasonjan.headnews.bean.news.MultiNewsArticleBean; import com.jasonjan.headnews.bean.news.MultiNewsArticleDataBean; import com.jasonjan.headnews.main.ErrorAction; import com.jasonjan.headnews.main.RetrofitFactory; import com.jasonjan.headnews.util.TimeUtil; import java.util.ArrayList; import java.util.List; import io.reactivex.Observable; import io.reactivex.annotations.NonNull; import io.reactivex.functions.Consumer; import io.reactivex.functions.Function; import io.reactivex.functions.Predicate; import io.reactivex.schedulers.Schedulers; /** * Created by JasonJan on 2017/12/14. */ public class VideoArticlePresenter implements IVideoArticle.Presenter{ private static final String TAG = "VideoArticlePresenter"; private IVideoArticle.View view; private String category; private String time; private Gson gson = new Gson(); private List<MultiNewsArticleDataBean> dataList = new ArrayList<>(); VideoArticlePresenter(IVideoArticle.View view) { this.view = view; this.time = TimeUtil.getCurrentTimeStamp(); } @Override public void doLoadData(String... category){ try { if (null == this.category) { this.category = category[0]; } } catch (Exception e) { ErrorAction.print(e); } // 释放内存 if (dataList.size() > 100) { dataList.clear(); } RetrofitFactory.getRetrofit().create(IMobileVideoApi.class) .getVideoArticle(this.category, time) .subscribeOn(Schedulers.io()) .observeOn(Schedulers.io()) .switchMap(new Function<MultiNewsArticleBean, Observable<MultiNewsArticleDataBean>>() { @Override public Observable<MultiNewsArticleDataBean> apply(@NonNull MultiNewsArticleBean multiNewsArticleBean) throws Exception { List<MultiNewsArticleDataBean> dataList = new ArrayList<>(); for (MultiNewsArticleBean.DataBean dataBean : multiNewsArticleBean.getData()) { dataList.add(gson.fromJson(dataBean.getContent(), MultiNewsArticleDataBean.class)); } return Observable.fromIterable(dataList); } }) .filter(new Predicate<MultiNewsArticleDataBean>() { @Override public boolean test(@NonNull MultiNewsArticleDataBean dataBean) throws Exception { time = dataBean.getBehot_time(); if (TextUtils.isEmpty(dataBean.getSource())) { return false; } try { // 过滤头条问答新闻 if (dataBean.getSource().contains("头条问答") || dataBean.getTag().contains("ad") || dataBean.getSource().contains("话题")) { return false; } } catch (NullPointerException e) { ErrorAction.print(e); } // 过滤重复新闻(与上次刷新的数据比较) for (MultiNewsArticleDataBean bean : dataList) { if (bean.getTitle().equals(dataBean.getTitle())) { return false; } } return true; } }) .toList() .compose(view.<List<MultiNewsArticleDataBean>>bindToLife()) .subscribe(new Consumer<List<MultiNewsArticleDataBean>>() { @Override public void accept(@NonNull List<MultiNewsArticleDataBean> list) throws Exception { doSetAdapter(list); } }, new Consumer<Throwable>() { @Override public void accept(@NonNull Throwable throwable) throws Exception { doShowNetError(); ErrorAction.print(throwable); } }); } @Override public void doLoadMoreData() { doLoadData(); } @Override public void doSetAdapter(List<MultiNewsArticleDataBean> dataBeen) { dataList.addAll(dataBeen); view.onSetAdapter(dataList); view.onHideLoading(); } @Override public void doRefresh() { if (dataList.size() != 0) { dataList.clear(); time = TimeUtil.getCurrentTimeStamp(); } doLoadData(); } @Override public void doShowNetError() { view.onHideLoading(); view.onShowNetError(); } }
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

public class NewsArticleVideoViewBinder extends ItemViewBinder<MultiNewsArticleDataBean,NewsArticleVideoViewBinder.ViewHolder> { private static final String TAG = "NewsArticleHasVideoView"; @NonNull @Override protected NewsArticleVideoViewBinder.ViewHolder onCreateViewHolder(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent) { View view = inflater.inflate(R.layout.item_news_article_video, parent, false); return new ViewHolder(view); } @Override protected void onBindViewHolder(@NonNull final NewsArticleVideoViewBinder.ViewHolder holder, @NonNull final MultiNewsArticleDataBean item) { final Context context = holder.itemView.getContext(); try { if (null != item.getVideo_detail_info()) { if (null != item.getVideo_detail_info().getDetail_video_large_image()) { String image = item.getVideo_detail_info().getDetail_video_large_image().getUrl(); if (!TextUtils.isEmpty(image)) { ImageLoader.loadCenterCrop(context, image, holder.iv_video_image, R.color.viewBackground, R.mipmap.error_image); } } } else { holder.iv_video_image.setImageResource(R.mipmap.error_image); } if (null != item.getUser_info()) { String avatar_url = item.getUser_info().getAvatar_url(); if (!TextUtils.isEmpty(avatar_url)) { ImageLoader.loadCenterCrop(context, avatar_url, holder.iv_media, R.color.viewBackground); } } String tv_title = item.getTitle(); holder.tv_title.setTextSize(SettingUtil.getInstance().getTextSize()); String tv_source = item.getSource(); String tv_comment_count = item.getComment_count() + "评论"; String tv_datetime = item.getBehot_time() + ""; if (!TextUtils.isEmpty(tv_datetime)) { tv_datetime = TimeUtil.getTimeStampAgo(tv_datetime); } int video_duration = item.getVideo_duration(); String min = String.valueOf(video_duration / 60); String second = String.valueOf(video_duration % 10); if (Integer.parseInt(second) < 10) { second = "0" + second; } String tv_video_time = min + ":" + second; holder.tv_title.setText(tv_title); holder.tv_extra.setText(tv_source + " - " + tv_comment_count + " - " + tv_datetime); holder.tv_video_time.setText(tv_video_time); holder.iv_dots.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { PopupMenu popupMenu = new PopupMenu(context, holder.iv_dots, Gravity.END, 0, R.style.MyPopupMenu); popupMenu.inflate(R.menu.menu_share); popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { @Override public boolean onMenuItemClick(MenuItem menu) { int itemId = menu.getItemId(); if (itemId == R.id.action_share) { IntentAction.send(context, item.getTitle() + " " + item.getShare_url()); } return false; } }); popupMenu.show(); } }); RxView.clicks(holder.itemView) .throttleFirst(1, TimeUnit.SECONDS) .subscribe(new Consumer<Object>() { @Override public void accept(@io.reactivex.annotations.NonNull Object o) throws Exception { // VideoContentActivity.launch(item); } }); } catch (Exception e) { ErrorAction.print(e); } } class ViewHolder extends RecyclerView.ViewHolder { private CircleImageView iv_media; private TextView tv_extra; private TextView tv_title; private ImageView iv_video_image; private TextView tv_video_time; private ImageView iv_dots; ViewHolder(View itemView) { super(itemView); this.iv_media = itemView.findViewById(R.id.iv_media); this.tv_extra = itemView.findViewById(R.id.tv_extra); this.tv_title = itemView.findViewById(R.id.tv_title); this.iv_video_image = itemView.findViewById(R.id.iv_video_image); this.tv_video_time = itemView.findViewById(R.id.tv_video_time); this.iv_dots = itemView.findViewById(R.id.iv_dots); } } }
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。

5.1.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。
