- 必须需要的四步骤代码如下所示
//设置播放类型 videoPlayer.setPlayerType(ConstantKeys.IjkPlayerType.TYPE_IJK); //设置视频地址和请求头部 videoPlayer.setUp(urls, null); //创建视频控制器 controller = new VideoPlayerController(this); //设置视频控制器 videoPlayer.setController(controller); - 开始播放
//播放视频 videoPlayer.start();
- 如下所示
//进入竖屏的全屏模式 videoPlayer.enterVerticalScreenScreen();
- 如下所示
//进入全屏模式 videoPlayer.enterFullScreen();
- 如下所示
//进入小窗口播放 videoPlayer.enterTinyWindow();
- 代码如下所示
mVideoPlayer.setPlayerType(ConstantKeys.IjkPlayerType.TYPE_IJK); VideoPlayerController controller = new VideoPlayerController(this); controller.setClarity(getClarites(), 0); mVideoPlayer.setController(controller); //设置清晰度的话，需要传递不同的视频链接 public List<VideoClarity> getClarites() { List<VideoClarity> clarities = new ArrayList<>(); clarities.add(new VideoClarity("标清", "270P", "http://play.g3proxy.lecloud.com/vod/v2/MjUxLzE2LzgvbGV0di11dHMvMTQvdmVyXzAwXzIyLTExMDc2NDEzODctYXZjLTE5OTgxOS1hYWMtNDgwMDAtNTI2MTEwLTE3MDg3NjEzLWY1OGY2YzM1NjkwZTA2ZGFmYjg2MTVlYzc5MjEyZjU4LTE0OTg1NTc2ODY4MjMubXA0?b=259&mmsid=65565355&tm=1499247143&key=f0eadb4f30c404d49ff8ebad673d3742&platid=3&splatid=345&playid=0&tss=no&vtype=21&cvid=2026135183914&payff=0&pip=08cc52f8b09acd3eff8bf31688ddeced&format=0&sign=mb&dname=mobile&expect=1&tag=mobile&xformat=super")); clarities.add(new VideoClarity("高清", "480P", "http://play.g3proxy.lecloud.com/vod/v2/MjQ5LzM3LzIwL2xldHYtdXRzLzE0L3Zlcl8wMF8yMi0xMTA3NjQxMzkwLWF2Yy00MTk4MTAtYWFjLTQ4MDAwLTUyNjExMC0zMTU1NTY1Mi00ZmJjYzFkNzA1NWMyNDc4MDc5OTYxODg1N2RjNzEwMi0xNDk4NTU3OTYxNzQ4Lm1wNA==?b=479&mmsid=65565355&tm=1499247143&key=98c7e781f1145aba07cb0d6ec06f6c12&platid=3&splatid=345&playid=0&tss=no&vtype=13&cvid=2026135183914&payff=0&pip=08cc52f8b09acd3eff8bf31688ddeced&format=0&sign=mb&dname=mobile&expect=1&tag=mobile&xformat=super")); clarities.add(new VideoClarity("超清", "720P", "http://play.g3proxy.lecloud.com/vod/v2/MjQ5LzM3LzIwL2xldHYtdXRzLzE0L3Zlcl8wMF8yMi0xMTA3NjQxMzkwLWF2Yy00MTk4MTAtYWFjLTQ4MDAwLTUyNjExMC0zMTU1NTY1Mi00ZmJjYzFkNzA1NWMyNDc4MDc5OTYxODg1N2RjNzEwMi0xNDk4NTU3OTYxNzQ4Lm1wNA==?b=479&mmsid=65565355&tm=1499247143&key=98c7e781f1145aba07cb0d6ec06f6c12&platid=3&splatid=345&playid=0&tss=no&vtype=13&cvid=2026135183914&payff=0&pip=08cc52f8b09acd3eff8bf31688ddeced&format=0&sign=mb&dname=mobile&expect=1&tag=mobile&xformat=super")); clarities.add(new VideoClarity("蓝光", "1080P", "http://play.g3proxy.lecloud.com/vod/v2/MjQ5LzM3LzIwL2xldHYtdXRzLzE0L3Zlcl8wMF8yMi0xMTA3NjQxMzkwLWF2Yy00MTk4MTAtYWFjLTQ4MDAwLTUyNjExMC0zMTU1NTY1Mi00ZmJjYzFkNzA1NWMyNDc4MDc5OTYxODg1N2RjNzEwMi0xNDk4NTU3OTYxNzQ4Lm1wNA==?b=479&mmsid=65565355&tm=1499247143&key=98c7e781f1145aba07cb0d6ec06f6c12&platid=3&splatid=345&playid=0&tss=no&vtype=13&cvid=2026135183914&payff=0&pip=08cc52f8b09acd3eff8bf31688ddeced&format=0&sign=mb&dname=mobile&expect=1&tag=mobile&xformat=super")); return clarities; }
- 代码如下所示
- 在recyclerView中
recyclerView.setRecyclerListener(new RecyclerView.RecyclerListener() { @Override public void onViewRecycled(RecyclerView.ViewHolder holder) { VideoPlayer videoPlayer = ((VideoAdapter.VideoViewHolder) holder).mVideoPlayer; if (videoPlayer == VideoPlayerManager.instance().getCurrentVideoPlayer()) { VideoPlayerManager.instance().releaseVideoPlayer(); } } });- 在adapter中，仅仅展示部分代码
@Override public VideoViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View itemView = LayoutInflater.from(mContext).inflate(R.layout.item_test_my_video, parent, false); VideoViewHolder holder = new VideoViewHolder(itemView); //创建视频播放控制器，主要只要创建一次就可以呢 VideoPlayerController controller = new VideoPlayerController(mContext); holder.setController(controller); return holder; } public class VideoViewHolder extends RecyclerView.ViewHolder { public VideoPlayerController mController; public VideoPlayer mVideoPlayer; VideoViewHolder(View itemView) { super(itemView); mVideoPlayer = (VideoPlayer) itemView.findViewById(R.id.nice_video_player); // 将列表中的每个视频设置为默认16:9的比例 ViewGroup.LayoutParams params = mVideoPlayer.getLayoutParams(); // 宽度为屏幕宽度 params.width = itemView.getResources().getDisplayMetrics().widthPixels; // 高度为宽度的9/16 params.height = (int) (params.width * 9f / 16f); mVideoPlayer.setLayoutParams(params); } /** * 设置视频控制器参数 * @param controller 控制器对象 */ void setController(VideoPlayerController controller) { mController = controller; mVideoPlayer.setPlayerType(ConstantKeys.IjkPlayerType.TYPE_IJK); mVideoPlayer.setController(mController); } void bindData(Video video) { mController.setTitle(video.getTitle()); //mController.setLength(video.getLength()); ImageUtil.loadImgByPicasso(itemView.getContext(),video.getImageUrl(),R.drawable.image_default,mController.imageView()); mVideoPlayer.setUp(video.getVideoUrl(), null); } }
- 代码如下所示
private boolean pressedHome; private HomeKeyWatcher mHomeKeyWatcher; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mHomeKeyWatcher = new HomeKeyWatcher(this); mHomeKeyWatcher.setOnHomePressedListener(new HomeKeyWatcher.OnHomePressedListener() { @Override public void onHomePressed() { pressedHome = true; } }); pressedHome = false; mHomeKeyWatcher.startWatch(); } @Override protected void onStop() { // 在OnStop中是release还是suspend播放器，需要看是不是因为按了Home键 if (pressedHome) { VideoPlayerManager.instance().suspendVideoPlayer(); } else { VideoPlayerManager.instance().releaseVideoPlayer(); } super.onStop(); mHomeKeyWatcher.stopWatch(); } @Override protected void onRestart() { mHomeKeyWatcher.startWatch(); pressedHome = false; super.onRestart(); VideoPlayerManager.instance().resumeVideoPlayer(); } @Override public void onBackPressed() { if (VideoPlayerManager.instance().onBackPressed()) { return; } super.onBackPressed(); }
- 和activity中一样，不同点在于处理fragment返回键逻辑
//在宿主Activity中设置代码如下 @Override protected void onStop() { super.onStop(); VideoPlayerManager.instance().releaseVideoPlayer(); } @Override public void onBackPressed() { if (VideoPlayerManager.instance().onBackPressed()) return; super.onBackPressed(); } //-------------------------------------------------- //在此Fragment中设置代码如下 @Override public void onStop() { super.onStop(); VideoPlayerManager.instance().releaseVideoPlayer(); }
- 默认是不显示这几个控件的，一般实际项目中，会对播放器做很多UI方面拓展
controller.setTopVisibility(true); - 给按钮设置点击事件
controller.setOnVideoControlListener(new OnVideoControlListener() { @Override public void onVideoControlClick(int type) { switch (type){ case ConstantKeys.VideoControl.DOWNLOAD: ToastUtils.showShort("下载"); break; case ConstantKeys.VideoControl.AUDIO: ToastUtils.showShort("转音频"); break; case ConstantKeys.VideoControl.SHARE: ToastUtils.showShort("分享"); break; case ConstantKeys.VideoControl.MENU: ToastUtils.showShort("更多"); break; case ConstantKeys.VideoControl.TV: ToastUtils.showShort("tv投影"); break; case ConstantKeys.VideoControl.HOR_AUDIO: ToastUtils.showShort("下载"); break; default: break; } } });
- 如下所示
//进入全屏模式 videoPlayer.enterFullScreen(); //进入竖屏的全屏模式 videoPlayer.enterVerticalScreenScreen(); //进入小窗口播放 //注意：小窗口播放视频比例是 16：9 videoPlayer.enterTinyWindow(); //释放，内部的播放器被释放掉，同时如果在全屏、小窗口模式下都会退出 videoPlayer.release(); //释放播放器，注意一定要判断对象是否为空，增强严谨性 videoPlayer.releasePlayer(); //设置播放器类型，必须设置 //输入值：ConstantKeys.IjkPlayerType.TYPE_IJK 或者 ConstantKeys.IjkPlayerType.TYPE_NATIVE videoPlayer.setPlayerType(ConstantKeys.IjkPlayerType.TYPE_NATIVE); //设置播放位置 videoPlayer.seekTo(100); //设置播放速度，不必须 videoPlayer.setSpeed(100); //设置视频链接 videoPlayer.setUp("",null); //设置音量 videoPlayer.setVolume(50); //是否从上一次的位置继续播放 videoPlayer.continueFromLastPosition(true);
- 如下所示
//关于视频播放相关api //获取缓冲区百分比 int bufferPercentage = videoPlayer.getBufferPercentage(); //获取播放位置 long currentPosition = videoPlayer.getCurrentPosition(); //获取当前播放模式 int currentState = videoPlayer.getCurrentState(); //获取持续时长 long duration = videoPlayer.getDuration(); //获取最大音量 int maxVolume = videoPlayer.getMaxVolume(); //获取当前播放状态 int playType = videoPlayer.getPlayType(); //获取播放速度 long tcpSpeed = videoPlayer.getTcpSpeed(); //获取音量值 int volume = videoPlayer.getVolume();
- 如下所示
//判断是否是否缓冲暂停 boolean bufferingPaused = videoPlayer.isBufferingPaused(); //判断视频是否正在缓冲(播放器正在播放时，缓冲区数据不足，进行缓冲，缓冲区数据足够后恢复播放) boolean bufferingPlaying = videoPlayer.isBufferingPlaying(); //判断视频是否播放完成 boolean completed = videoPlayer.isCompleted(); //判断视频是否播放错误 boolean error = videoPlayer.isError(); //判断视频是否播放全屏 boolean fullScreen = videoPlayer.isFullScreen(); //判断是否开始播放 boolean idle = videoPlayer.isIdle(); //判断视频是否正常播放 boolean normal = videoPlayer.isNormal(); //判断视频是否暂停播放 boolean paused = videoPlayer.isPaused(); //判断视频是否正在播放 boolean playing = videoPlayer.isPlaying(); //判断视频是否准备就绪 boolean prepared = videoPlayer.isPrepared(); //判断视频是否播放准备中 boolean preparing = videoPlayer.isPreparing(); //判断视频是否播放小窗口 boolean tinyWindow = videoPlayer.isTinyWindow(); //开始播放 videoPlayer.start(); //暂停播放 videoPlayer.pause(); //开始播放 videoPlayer.start(100); //重新播放 videoPlayer.restart();
- 如下所示
//设置是否显示视频头部的下载，分享，其他等控件是否显示 controller.setTopVisibility(true); controller.setTop(20); //设置top到顶部的距离 controller.setTopPadding(30); //设置加载loading类型 controller.setLoadingType(ConstantKeys.Loading.LOADING_RING); //设置不操作后，多久自动隐藏头部和底部布局 controller.setHideTime(8000); //设置中间播放按钮是否显示，并且支持设置自定义图标 controller.setCenterPlayer(true,R.drawable.image_default); //获取ImageView的对象 ImageView imageView = controller.imageView(); //重新设置 controller.reset(); //设置图片 controller.setImage(R.drawable.ic_back_right); //设置视频时长 controller.setLength(1000); //设置视频标题 controller.setTitle("小杨逗比"); boolean lock = controller.getLock(); //设置横屏播放时，tv和audio图标是否显示 controller.setTvAndAudioVisibility(true,true); //让用户自己处理返回键事件的逻辑 controller.setOnVideoBackListener(new OnVideoBackListener() { @Override public void onBackClick() { } }); //播放暂停监听事件 controller.setOnPlayOrPauseListener(new OnPlayOrPauseListener() { @Override public void onPlayOrPauseClick(boolean isPlaying) { } }); //监听视频播放完成事件 controller.setOnCompletedListener(new OnCompletedListener() { @Override public void onCompleted() { } }); //设置视频分享，下载，音视频转化点击事件 controller.setOnVideoControlListener(new OnVideoControlListener() { @Override public void onVideoControlClick(int type) { } });
- 如下所示
//VideoPlayerManager对象 VideoPlayerManager instance = VideoPlayerManager.instance(); //当视频暂停时或者缓冲暂停时，调用该方法重新开启视频播放 instance.resumeVideoPlayer(); //当视频正在播放或者正在缓冲时，调用该方法暂停视频 instance.suspendVideoPlayer(); //释放，内部的播放器被释放掉，同时如果在全屏、小窗口模式下都会退出 instance.releaseVideoPlayer(); //处理返回键逻辑 //如果是全屏，则退出全屏 //如果是小窗口，则退出小窗口 instance.onBackPressed(); //获取对象 VideoPlayer currentVideoPlayer = instance.getCurrentVideoPlayer(); //设置VideoPlayer instance.setCurrentVideoPlayer(videoPlayer);
