Android仿今日头条的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：

         adapter = new VideoAdapter(VideoActivity. this , datas, R.layout.item_video);
         listView.setAdapter(adapter);

     private void autoPlayVideo(AbsListView view) {
  
         for ( int i = 0 ; i < visibleCount; i++) {
             if (view != null && view.getChildAt(i) != null && view.getChildAt(i).findViewById(R.id.player_list_video) != null ) {
                 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

compile 'com.zhy:base-adapter:3.0.3' <ul class = "pre-numbering" > 1 <img src= "/uploadfile/Collfiles/20170721/20170721093008222.png" style= "width: 105px; height: 60px;" ><ul class = "pre-numbering" > 1 </ul></ul>

下面我们看看最终的效果

这里写图片描述

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
