视频播放控件实现教程（几行代码快速实现）

前段时间由于项目需要用到类似于今日头条的视频播放器，实现在线播放，边缓存边播放，当然也可以播放本地文件，如下图：

这里写图片描述

这里我推荐大家使用的是jiecaovideoplayer开源库，这个库的播放引擎是ijkplayer，它调用ffmpeg， 原项目GitHub地址：https://github.com/lipangit/JieCaoVideoPlayer

一、项目引入：

1、添加类库

?

1

2

compile 'fm.jiecao:jiecaovideoplayer:4.8.3'

compile 'com.github.bumptech.glide:glide:3.7.0'

2、添加布局

?

1

<fm.jiecao.jcvideoplayer_lib.jcvideoplayerstandard android:id="@+id/player_list_video" android:layout_width="match_parent" android:layout_height="220dp"></fm.jiecao.jcvideoplayer_lib.jcvideoplayerstandard>

3、下面就是我所说的通过设置视频地址、缩略图地址、标题等几行代码快速实现视频的播放啦

?

JCVideoPlayerStandard player = (JCVideoPlayerStandard) findViewById(R.id.player_list_video);

       boolean setUp = player.setUp("https://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4", JCVideoPlayer.SCREEN_LAYOUT_LIST, "");

       if (setUp) {

           Glide.with(MainActivity.this).load("https://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);

       }

4、在Activity中

?

@Override

    public void onBackPressed() {

        if (JCVideoPlayer.backPress()) {

            return;

        }

        super.onBackPressed();

    }

  

    @Override

    protected void onPause() {

        super.onPause();

        JCVideoPlayer.releaseAllVideos();

    }

5、还有一点不要忘记哦，要添加权限滴：

?

1

2

<!--联网权限-->

    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

下面我们来看看我们运行效果：

这里写图片描述

二、如何使用jiecaovideoplayer播放本地视频

注意：jiecaovideoplayer支持file:///开头的文件播放，但是不支持assets或者raw目录下的视频，assets下的视频要先复制到本地路径才能播放，至于怎么监听播放完全呢，要继承JCvideoPlayerStandard 复写onAutoCOmplete函数

三、模拟用户点击开始按钮，直接进入全屏

?

1

2

3

4

//直接进入全屏

       player.startFullscreen(this, JCVideoPlayerStandard.class, videoUrl, "");

       //模拟用户点击开始按钮，NORMAL状态下点击开始播放视频，播放中点击暂停视频

       player.startButton.performClick();

我把代码都贴出来吧：

        }

        super.onBackPressed();

        super.onPause();

        JCVideoPlayer.releaseAllVideos();

    }

                currPlayer = (JCVideoPlayerStandard) view.getChildAt(i).findViewById(R.id.player_list_video);

                Rect rect = new Rect();

                //获取当前view 的 位置

                currPlayer.getLocalVisibleRect(rect);

                int videoheight = currPlayer.getHeight();

                if (rect.top == 0 && rect.bottom == videoheight) {

                    if (currPlayer.currentState == JCVideoPlayer.CURRENT_STATE_NORMAL

                            || currPlayer.currentState == JCVideoPlayer.CURRENT_STATE_ERROR) {

                        currPlayer.startButton.performClick();

                    }

                    return;

                }

            }

        }

        //释放其他视频资源

        JCVideoPlayer.releaseAllVideos();

    }

  

    @Override

    public void onBackPressed() {

        if (JCVideoPlayer.backPress()) {

            return;

        }

        super.onBackPressed();

    }

  

    @Override

    protected void onPause() {

        super.onPause();

        JCVideoPlayer.releaseAllVideos();

    }

}<img src="/uploadfile/Collfiles/20170721/20170721093008222.png" style="width: 105px; height: 60px;"></string></string>

在我们滑动的时候，jiecaovideoplayer会自动停止正在播放的视频，这里面我还添加了一个功能，就是监听当滑动停止的时候自动播放下一个视频

这里的适配器，我继承了鸿洋大神写的万能的Adapter，所以我们还需添加这个库的引用

好了，本篇文章已经全部写完但是当在fragment中加载视屏时无法全屏播放，不知道为啥
