android recyclerview列表播放视频视频全屏翻页自动播放高仿微视之路

我这文章暂时是打广告的,要使用列表播放的朋友

视频效果

要做2件事情,第一 要监听recyclerview的滚动状态变为空闲的时候寻找videoview 进行播放

第二 ,要再recyclerview的布局改变的时候也寻找videoview进行播放

第三 让视频无缝无白屏闪屏播放

所以我就不用国内的这些第三方了,感觉摸不着头脑,y因为搞不到为何findview之后调用播放按钮竟然毛线反应没有,

于是找到了一个国外的,但是有很多坑 我修改了好几天,解决了白闪问题,增加了缓冲的显示,增加了点击播放暂停的控制

使用方法

compile 'cn.qssq666:video-player-manager:0.5'

如果多个界面都有列表视频播放 mVideoPlayerManager那么在界面不可见的时候各位要进行暂停或者销毁
创建单例管理器

fragment或activity的处理

构建管理器
   mVideoPlayerManager = new SingleVideoPlayerManager(new PlayerItemChangeListener() {
            @Override
            public void onPlayerItemChanged(MetaData metaData) {

            }


        }
        ) {
            @Override
            public void onVideoPlayTimeChanged(int positionInMilliseconds) {
                float duration = mVideoPlayerManager.getCurrentPlayer().getDuration();
                int percent = (int) (positionInMilliseconds / duration * 100f); //   int shouldSetWidth = (int) ((getWidth() / (float) mMaxProgress) * progress);
                if (BuildConfig.DEBUG) {
                    if (binding != null) {
                        binding.progressBar.setProgress(percent);
                    }
                    Log.w(TAG, "percent:" + percent);
                }
            }

            @Override
            public void onPrepare() {
                binding.progressBar.setProgress(0);
            }
        };

监听recyclerview的滚动
   binding.viewpager.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                int actualCurrentPosition = 0;
                if (newState == RecyclerView.SCROLL_STATE_IDLE) {
                    //第一次没法解决
  
                    autoPlayVideo(binding.viewpager);//每次滚动一页就自动播放

                }

            }
        });
//解决第一次打开界面不播放问题
        binding.viewpager.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                autoPlayVideo(binding.viewpager);
                Log.w(TAG,"V"+left+",top:"+top+",right:"+right+",bottom:"+bottom+",oldLeft:"+oldLeft+",oldTop:"+oldTop+",oldRight:"+oldRight);

            }
        });
自动播放的具体逻辑

    private void autoPlayVideo(RecyclerView view) {


        RecyclerView.LayoutManager layoutManager = view.getLayoutManager();
        int actualCurrentPosition = binding.viewpager.getCurrentPosition();


        MetaData metaData = new MetaData() {

        };


        GenericDataBindViewHolder holder = (GenericDataBindViewHolder) binding.viewpager.findViewHolderForLayoutPosition(actualCurrentPosition);
        if (holder == null) {
            Log.e(TAG,"找不到viewholder");
            return;
        }
        SmallVideoModel model1 = getAdapter().getData().get(actualCurrentPosition);
        if (mVideoPlayerManager.isCurrent(model1.getVideo())) {
            if(BuildConfig.DEBUG){
                Log.w(TAG,"是当前视频,忽略");
            }
            return;
        }
        holder.getBinding().progressbar.setProgress(0);//
        holder.getBinding().progressWrap.setVisibility(View.VISIBLE);
        holder.getBinding().btnStart.setVisibility(View.GONE);
        SmallVideoModel model = getAdapter().getData().get(actualCurrentPosition);
        mVideoPlayerManager.playNewVideo(metaData, holder.getBinding().videoPlayer2, model.getVideo());
    }
页面声明周期控制

    @Override
    public void onDestroy() {
        super.onDestroy();
        if (mVideoPlayerManager != null) {

            mVideoPlayerManager.stopAnyPlayback();
        }

    }

    @Override
    public void onResume() {
        super.onResume();
        if (mFromActivity) {
            return;
        }
        Log.w(TAG, "PLAYSTEATE:" + mVideoPlayerManager.getCurrentPlayerState());
        mVideoPlayerManager.continuePlay();
    }

    @Override
    public void onPause() {
        super.onPause();
        if (mFromActivity) {
            return;
        }

        Log.w(TAG, "PLAYSTEATE:" + mVideoPlayerManager.getCurrentPlayerState());
        mVideoPlayerManager.pause();
    }

监听视频透明封面的点击

请注意,这里播放视频是用管理器去操作播放,而不是通过布局的videoPlayer2

        View.OnClickListener l = new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (mVideoPlayerManager.isCurrent(model.getVideo())) {
                    if (mVideoPlayerManager.isPause()) {
                        mVideoPlayerManager.continuePlay();
                    } else if (mVideoPlayerManager.isPlay()) {
                        mVideoPlayerManager.pause();
                    } else {
                        mVideoPlayerManager.playNewVideo(model, binding.videoPlayer2, model.getVideo());
                    }
                } else {

                    binding.btnStart.setVisibility(View.GONE);  binding.progressWrap.setVisibility(View.VISIBLE);binding.progressText.setText("0%");
                    mVideoPlayerManager.playNewVideo(model, binding.videoPlayer2, model.getVideo());

                }
            }
        };
        binding.videoPlayerMask.setOnClickListener(l);
添加监听

        binding.videoPlayer2.addMediaPlayerListener(new MediaPlayerWrapper.MainThreadMediaPlayerListener() {
            @Override
            public void onVideoSizeChangedMainThread(int width, int height) {
            }

            @Override
            public void onVideoPreparedMainThread() {

            }

            //作废
            @Override
            public void onProgressUpdate(int percent) {


//                binding.seekbar.setProgress();
            }

            @Override
            public void onVideoCompletionMainThread() {
                binding.videoPlayer2.restart();//播放完毕重新开始
            }

            @Override
            public void onErrorMainThread(int what, int extra) {


                binding.progressWrap.setVisibility(View.GONE);
                binding.btnStart.setVisibility(View.VISIBLE);//这里少写了一个,应该让封面也显示出来
            }

            @Override
            public void onBufferingUpdateMainThread(int percent) {
                if (percent == 100) {
                    if (binding.progressWrap.getVisibility() == View.VISIBLE) {

                        binding.progressWrap.setVisibility(View.GONE);
                    }

                } else {
                    if (binding.progressWrap.getVisibility() == View.GONE) {
                        binding.progressWrap.setVisibility(View.VISIBLE);
                    }
                    binding.progressbar.setProgress(percent);
                    binding.progressText.setText("" + percent + "%");

                }

            }

            @Override
            public void onVideoStoppedMainThread() {
                // Show the cover when video stopped
                binding.iv.setVisibility(View.VISIBLE);
                binding.btnStart.setVisibility(View.VISIBLE);
                binding.progressWrap.setVisibility(View.GONE);
            }

            @Override
            public void onPrepared(MediaPlayer mp) {
//                binding.ivStart.setVisibility(View.g);
            }

            @Override
            public void onPrepare() {


                binding.progressWrap.setVisibility(View.VISIBLE);
                binding.btnStart.setVisibility(View.GONE);//即将要请求网络,说明有人调用了播放了.这一般是耗时的,第一次播放一个数据源才回调
            }

            @Override
            public void onVideoPausedMainThread() {
                binding.iv.setVisibility(View.VISIBLE);
                binding.progressWrap.setVisibility(View.GONE);
                binding.btnStart.setVisibility(View.VISIBLE);//即将要请求网络,说明有人调用了播放了.这一般是耗时的,第一次播放一个数据源才回调


            }

            @Override
            public void onVideoStartedMainThread() {
                binding.btnStart.setVisibility(View.GONE);//即将要请求网络,说明有人调用了播放了.这一般是耗时的,第一次播放一个数据源才回调

            }

            @Override
            public void onInfo(MediaPlayer mp, int what, int extra) {
                if (what == MediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START) {//解决白屏问题
                    binding.iv.setVisibility(View.INVISIBLE);
                    binding.progressWrap.setVisibility(View.GONE);
                }
            }
        });

这里不会泄露,因为每次滑动到下一个视频,那么上一个视频的所有监听都会被移除、销毁。

ok列表播放的就到这里了,但是可能还会有一些体验需要优化,特别是处理继续播放的时候。
我这是高仿微视,他那个整个播放进度是在一个tab选项卡的上面,当缓冲的时候是进度从中间往两边散开,循环模式,所以播放进度这里不需要单独再写,而是在上面的管理器代码里面控制fragmet进度横条的显示,要知道整个进度特效如何实现的朋友可以看看我的githuballproject目录导航

其实这个项目还有很多不足,毕竟只是实现了列表播放,为了做优化,我的demo做了一个可显示进度显示时间,可暂停播放继续播放的 demo.可以去github下载看看。和大部分播放器一样,在界面销毁的时候调用销毁方法就可以解决泄露问题了
