今天做的是一个看电视台直播的功能。
MainActivity的布局是listView，直播布局页面写的是videoview中嵌套上下的一个panel和加载的一个动画。
上面的显示的是卫视名称和当前的时间。
需要注意的是直播源，也就是播放的卫视的网址链接，需要去在网上找或者是自己去抓取，网上找的话推荐去
这个网站去找，也给大家推荐一个我自己用的：
点击HDP直播，然后找上图这种的点开就会有网址链接，但是不一定有效。需要自己去测试。
这样的话就需要你去下载一个VLC软件，打开后点击File-network，利用网络串流输入你找的这个网址链接测试是否有效。有效的话他就会播放电视台的直播。也就意味着你可用在你的代码中。
这个软件还用了vitamio框架，可以去github上下载：
1、在你的项目建立一个model下的android library，或者直接而将vitamio导入你的android项目-File->new->Import Module，导入vitmio文件夹。注意的是导入之后vitamio目录下的build.gradle中配置，要和app目录下的build.gradle中的配置相同：
2、在你的app的build下dependence中加入依赖implementation project(':vitamoi')
3、需要在AndroidManifest中加入权限
4、需要在Application中vitamio初始化Activity，和下图面一样。
切记：我们代码中的videoview和Mediaplayer用的都是vitamio中的。hander用的是原生自带的android.os. 。
