android使用video开发简单的视频播放!

由于做资讯类的app,所以涉及到的与h5交互的情况比较多。。。由于项目以前用的是优酷的视频外链。app可以直接用webview 来播放,优酷那边已经做过处理。所以webview那儿可以直接播放。但是现在视屏都上传自己服务器,资讯视屏也用h5原生的。导致app端无法全屏播放视频。网上也有很多方法来解决不是全屏问题,但是曲线救国,有点。。。不予评论。。。

于是乎,决定自己写个简易播放器来全屏播放,一般有三种方式,1。直接用系统的播放器。2.用videoview+mediacontroller 来播放。3.用sufaceview+mediacontroller

由于需要纪录播放进度。所以第一种直接弃用,开发时间有限,所以就决定 用第二种。第三种方法适合定制性比较高。功能比较齐全的。但是相对复杂的,我也尝试过

只是做了简单的播放处理。关于第三种,网上有的博客忘记写了, 就是 media 发起异步准备的时候,一定要在onPrepared准备的方法里 start一下,否则无法播放。



在此 其他的不做过多的叙述,视屏链接如何获取也不予详细说明。网上有很多种。我的大致思路就是与h5开发人员 约定一个 超链接。我用webview 的方法截取超

链接。来解析获取url。

接下来,请欣赏核心代码 简易 视屏播放器。大神请绕道。思路是 这样的,(因为22版本sdk进度条特别的。。那啥。23版本的还阔以,但是项目的 build版本22 没办法,所以决定,设置控制器后,隐藏掉它自己的显示界面,自定义自己的控制器,加监听。加功能)


布局文件 很简单。

哦, 对了。最后别忘记在 manifest 里注册 activity 为横屏

一个简易的视频播放器 完成。。。

补充:

public class CustomVideoView extends VideoView {
    public static int mVideoWidth;
    public static int mVideoHeight;

    private Context context;

    public CustomVideoView(Context context) {
        super(context);
