Android TV直播电视节目，包含各央视频道及卫视频道

传统电视直播节目，在Android TV上起着越来越重要的作用，央视，各地卫视，满足观众日益增长的多元化需求看下效果图： 代码实现思路： 如图1所示，通过RecycleView为对应的节目项，遥控器按键，可触发跳到对应的直播节目 2，用对IjkPlayer进行二次封装，并能用于播放视频源。 3，视频源M3U8，可能存在失效，目前获取了一个比较稳定的视频源 代码实现： 主页面：Recycleview对应adapater 直播节目源 播放器 播放页处理 主页面： /* * Copyright (C) 2016 hejunlin <[email]hejunlin2013@gmail.com[/email]> * Licensed under the Apache License, Version 2.0 (the "License");
