做过Android视频播放器的码农们都或多或少知道自带的VideoView用着没有那么顺心。需要处理很多东西。于是就各种度娘、Google。终于皇天不负苦心人。找到了一个却又不大符合。无奈，想自己动手写吧！又浪费时间。在这里，附上一个采用Vitamio框架写的视频播放器贡献给大伙。希望对你有用。好了。进入正题：
附上github下载地址：https://github.com/eternityzqf/VitamioTestDemo
先来个效果图看看：
图片可能有点糙，但运行在手机上是没问题的。

①：播放网络视频
②：可以实现缓存/缓存加载提示
③：竖屏缩放正常画面、横屏缩放全屏画面
④：滑动左边亮度调节、滑动右边调节声音
⑤：自定义媒体控制画面。增加扩展性。

一、App：用于全局初始化VItamio

}自定义控制器类主要是最播放、暂停、播放时间、全屏的一些控件界面封装；通过在MainActivity里面的
new CustomMediaController();将VideoView传进来进行一些操作。但播放的相关还是放在主界面里面操作的。
可在里面更改界面以适应需求。SeekBar样式都将采用自定义的。增加扩展。
涉及的公共方法：
setVideoName();设置视频名称
当然还有什么添加喜欢，收藏子类的。你们都可以自己添加。

}
}
主界面里面
一、
先看看Vitamio的VideoView都带有什么功能；
设置缓存大小（单位Byte）：
mVideoView.setBufferSize(512 * 1024)；监听在有警告或错误信息时调用。例如：开始缓冲、缓冲结束、下载速度变化：
mVideoView.setOnInfoListener(this); @Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
switch (what) {
case MediaPlayer.MEDIA_INFO_BUFFERING_START:
//开始缓存事，执行暂停播放、加载、下载、缓存控件可见
if (mVideoView.isPlaying()) {
Log.e("Tag", what + "---缓存flag----");
mVideoView.pause();
pb.setVisibility(View.VISIBLE);
downloadRateView.setVisibility(View.VISIBLE);
loadRateView.setVisibility(View.VISIBLE);
}
break;
case MediaPlayer.MEDIA_INFO_BUFFERING_END:
//缓存完成，执行继续播放；加载、下载、缓存控件不可见
mVideoView.start();
pb.setVisibility(View.GONE);
downloadRateView.setVisibility(View.GONE);
loadRateView.setVisibility(View.GONE);
break;
case MediaPlayer.MEDIA_INFO_DOWNLOAD_RATE_CHANGED:
//缓存时显示下载速度
//此时下载速度应该实时获取手机的网速。这以kb/s代替
Log.e("Tag", what + "----下载flag---" + extra);
downloadRateView.setText(extra + "kb/s" + "");
break;
}
return true;
}监听在网络视频流缓冲变化时调用：
mVideoView.setOnBufferingUpdateListener(this); @Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
loadRateView.setText("缓冲" + percent + "%");
Log.e("Tag", "+++++++" + percent);
}二、手机Home切换到候后台时我们需要在生命周期里面记录和恢复播放位置：
记录：
@Override
protected void onPause() {
super.onPause();
Log.e("Tag", "onPause");
mCurrent_position = mVideoView.getCurrentPosition();
Log.e("Tag", mCurrent_position + "");
if (mVideoView.isPlaying()) {
mVideoView.pause();
}
}
恢复：
@Override
protected void onResume() {
super.onResume();
Log.e("Tag", "onResume");
if (mCurrent_position != 0) {
mVideoView.seekTo(mCurrent_position);
mVideoView.start();
}
}当然我们还需要在ConfigurationChanged里面改一下;
@Override
public void onConfigurationChanged(Configuration newConfig) {
Log.e("Tag", newConfig.orientation + "");
if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
//竖屏-->显示原始画面
if (mVideoView != null) {
mVideoView.setVideoLayout(VIDEO_LAYOUT_ORIGIN, 0);
}
} else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
//横屏-->显示全屏画面
if (mVideoView != null) {
mVideoView.setVideoLayout(VIDEO_LAYOUT_SCALE, 0);
}
}
super.onConfigurationChanged(newConfig);
}差不多就这些，有些细节就没贴出来。可以去github下来看看。欢迎各位star和fork。
