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。
功能点：
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。
主要类：
一、App：用于全局初始化VItamio
/** * class from * Created by zqf * Time 2017/7/25 15:43 */ public class App extends Application { @Override public void onCreate() { super.onCreate(); //初始化一次Vitamio Vitamio.isInitialized(this); } }

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。
三、ManActivity：主界面
/** * class from 主界面 * Created by zqf * Time 2017/7/25 15:43 */ public class MainActivity extends Activity implements MediaPlayer.OnInfoListener, MediaPlayer.OnBufferingUpdateListener, MediaPlayer.OnCompletionListener { private String video_path = "http://baobab.wdjcdn.com/145076769089714.mp4"; private Uri mUri; private ProgressBar pb; private TextView downloadRateView, loadRateView; private CustomMediaController mCustomMediaController; private VideoView mVideoView; public static long mCurrent_position = 0;//当前播放的位置 public static final int VIDEO_LAYOUT_ORIGIN = 0;//缩放参数，原始画面大小0。 public static final int VIDEO_LAYOUT_SCALE = 1;//缩放参数，画面全屏1。 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //定义全屏参数 int flag = WindowManager.LayoutParams.FLAG_FULLSCREEN; //获得当前窗体对象 Window window = MainActivity.this.getWindow(); //设置当前窗体为全屏显示 window.setFlags(flag, flag); setContentView(R.layout.activity_main); initView(); initData(); } private void initData() { mUri = Uri.parse(video_path);//将地址转化为Uri mVideoView.setVideoURI(mUri);//设置播放视频的地址 mCustomMediaController.show(5000);//设置显示时间差 mVideoView.setMediaController(mCustomMediaController);//设置媒体控制器。 mVideoView.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);//设置画质 mVideoView.requestFocus();//获取焦点 mVideoView.setBufferSize(512 * 1024);//设置缓冲大小（单位Byte） /** * 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); /** * 监听在网络视频流缓冲变化时调用。 */ mVideoView.setOnBufferingUpdateListener(this); /** * 视频播放完成后调用。 */ mVideoView.setOnCompletionListener(this); mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { /** * 在视频预处理完成后调用。在视频预处理完成后被调用。 * 此时视频的宽度、高度、宽高比信息已经获取到， * 此时可调用seekTo让视频从指定位置开始播放。 */ mp.setPlaybackSpeed(1.0f); } }); } private void initView() { mVideoView = (VideoView) findViewById(R.id.vitamio_video); mCustomMediaController = new CustomMediaController(this, mVideoView, this); mCustomMediaController.setVideoName("此处可以设置视频名称"); pb = (ProgressBar) findViewById(R.id.probar); downloadRateView = (TextView) findViewById(R.id.download_rate); loadRateView = (TextView) findViewById(R.id.load_rate); } @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; } @Override public void onBufferingUpdate(MediaPlayer mp, int percent) { loadRateView.setText("缓冲" + percent + "%"); Log.e("Tag", "+++++++" + percent); } @Override protected void onResume() { super.onResume(); Log.e("Tag", "onResume"); if (mCurrent_position != 0) { mVideoView.seekTo(mCurrent_position); mVideoView.start(); } } @Override protected void onPause() { super.onPause(); Log.e("Tag", "onPause"); mCurrent_position = mVideoView.getCurrentPosition(); Log.e("Tag", mCurrent_position + ""); if (mVideoView.isPlaying()) { mVideoView.pause(); } } @Override protected void onStop() { super.onStop(); Log.e("Tag", "onStop"); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); Log.e("Tag", "onRestoreInstanceState"); } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); Log.e("Tag", "onSaveInstanceState"); } @Override protected void onDestroy() { super.onDestroy(); Log.e("Tag", "onDestroy"); //停止视频播放，并释放资源。 mVideoView.stopPlayback(); mCurrent_position = 0; } /** * 视频播放完成后调用。 * * @param mp the MediaPlayer that reached the end of the file */ @Override public void onCompletion(MediaPlayer mp) { mCurrent_position = 0; } /** * getRequestedOrientation获取横竖屏标志 * -1 || 1--->竖屏 * 0 --->横屏 */ @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { Log.e("Tag", "返回键。。。。" + getRequestedOrientation()); int orient = getRequestedOrientation(); if (orient == -1 || orient == 1) { finish(); } else if (orient == 0) { //切换为竖屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } return false; } return super.onKeyDown(keyCode, event); } /** * 屏幕切换时 */ @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); } }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。
