篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了TouTiao开源项目 分析笔记12 从总体到局部 构建视频主页面相关的知识，希望对你有一定的参考价值。
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）
