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。

@Override

} catch (Exception e) {
ErrorAction.print(e);
}
// 释放内存

dataList.clear();
}
RetrofitFactory.getRetrofit().create(IMobileVideoApi.class)
.getVideoArticle(this.category, time)
.subscribeOn(Schedulers.io())

for (MultiNewsArticleBean.DataBean dataBean : multiNewsArticleBean.getData()) {

}
return true;

})
.toList()
.compose(view.<List<MultiNewsArticleDataBean>>bindToLife())

@Override
public void accept(@NonNull List<MultiNewsArticleDataBean> list) throws Exception {
doSetAdapter(list);
}
}, new Consumer<Throwable>() {
@Override

ErrorAction.print(throwable);
}
});
}
@Override

@Override

dataList.addAll(dataBeen);
view.onSetAdapter(dataList);

}
@Override
public void doRefresh() {

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();

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。
