AndroidVideoPlayer

本项目，简单的实现和集成了Android系统下常见的视频播放器；
   包括：videoview
        Surfaceview
        Vitamio集成使用
        Bilibili框架集成

1.VideoView 实现播放效果 

     vv = (VideoView) findViewById(R.id.vv);
            final File file = new File("/storage/emulated/0/Movies/Starry_Night.mp4");
    
            // 创建一个MediaController。
            // 这里的Context一定要传入this，不能用getApplicationContext().否则一点击屏幕就闪退
            mc = new MediaController(this);
    
            // 开创建SurfaceView的控制器
            SurfaceHolder holder = vv.getHolder();
    
            holder.addCallback(new SurfaceHolder.Callback() {
    
                @Override
                public void surfaceCreated(SurfaceHolder holder) {
    
                    if (file.exists()) {
                        // 设置要播放的视频
                        vv.setVideoPath(file.getPath());
    
                        // 设置VideoView与MediaController相关联
                        vv.setMediaController(mc);
    
                        // 设置VideoView获取焦点
                        vv.requestFocus();
    
                        // 将背景图片设为透明
                        // vv.getBackground().setAlpha(0);
    
                        // 开始播放视频（如果上次有播放记录，接着上次播放）
                        vv.start();
                        vv.seekTo(secondCurrentPosition);
    
                    } else {
                        Toast.makeText(getApplicationContext(), "视频不存在", Toast.LENGTH_SHORT).show();
                    }
    
                }
    
                @Override
                public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
                }
    
    
                @Override
                public void surfaceDestroyed(SurfaceHolder holder) {
                }
            });
    
            // 设置播放完毕后循环播放
            vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    
                @Override
                public void onCompletion(MediaPlayer mp) {
                    mp.seekTo(0);
                    mp.start();
                }
            });
    
            // 增加监听上一个和下一个的切换事件，默认这两个按钮是不显示的
            mc.setPrevNextListeners(new View.OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    // 这里直接弹出吐司，开发中这里应当切换到下一首
                    Toast.makeText(VideoViewActivity.this, "下一个", Toast.LENGTH_SHORT).show();
                }
            }, new View.OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    Toast.makeText(VideoViewActivity.this, "上一个", Toast.LENGTH_SHORT).show();
                }
            });
    
        }
    
        //当Activity退出界面(无论Activity是否销毁了)，记录当前视频播放进度
        @Override
        protected void onPause() {
            if (vv.isPlaying()) {
                secondCurrentPosition = vv.getCurrentPosition();
                vv.pause();
                vv.suspend();
            }
    
            super.onPause();
        }


2.SurfaceView + MediaPlayer（详情见代码，这里是第一种方法，不带进度条和控制栏的）
    
     vv = (VideoView) findViewById(R.id.vv);
            final File file = new File("/storage/emulated/0/Movies/Starry_Night.mp4");
    
            // 创建一个MediaController。
            // 这里的Context一定要传入this，不能用getApplicationContext().否则一点击屏幕就闪退
            mc = new MediaController(this);
    
            // 开创建SurfaceView的控制器
            SurfaceHolder holder = vv.getHolder();
    
            holder.addCallback(new SurfaceHolder.Callback() {
    
                @Override
                public void surfaceCreated(SurfaceHolder holder) {
    
                    if (file.exists()) {
                        // 设置要播放的视频
                        vv.setVideoPath(file.getPath());
    
                        // 设置VideoView与MediaController相关联
                        vv.setMediaController(mc);
    
                        // 设置VideoView获取焦点
                        vv.requestFocus();
    
                        // 将背景图片设为透明
                        // vv.getBackground().setAlpha(0);
    
                        // 开始播放视频（如果上次有播放记录，接着上次播放）
                        vv.start();
                        vv.seekTo(secondCurrentPosition);
    
                    } else {
                        Toast.makeText(getApplicationContext(), "视频不存在", Toast.LENGTH_SHORT).show();
                    }
    
                }
    
                @Override
                public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
                }
    
    
                @Override
                public void surfaceDestroyed(SurfaceHolder holder) {
                }
            });
    
            // 设置播放完毕后循环播放
            vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    
                @Override
                public void onCompletion(MediaPlayer mp) {
                    mp.seekTo(0);
                    mp.start();
                }
            });
    
            // 增加监听上一个和下一个的切换事件，默认这两个按钮是不显示的
            mc.setPrevNextListeners(new View.OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    // 这里直接弹出吐司，开发中这里应当切换到下一首
                    Toast.makeText(VideoViewActivity.this, "下一个", Toast.LENGTH_SHORT).show();
                }
            }, new View.OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    Toast.makeText(VideoViewActivity.this, "上一个", Toast.LENGTH_SHORT).show();
                }
            });
    
        }
    
        //当Activity退出界面(无论Activity是否销毁了)，记录当前视频播放进度
        @Override
        protected void onPause() {
            if (vv.isPlaying()) {
                secondCurrentPosition = vv.getCurrentPosition();
                vv.pause();
                vv.suspend();
            }
    
            super.onPause();
        }

3.Vitamio 第三方框架

            netSpeedTv = (TextView) findViewById(R.id.net_speed);
    
            //初始化加载库文件
