Android 视频播放器dkplayer

列表播放如图所示：

一、依赖

     //添加RecyclerView的依赖包
    implementation 'androidx.recyclerview:recyclerview:1.2.1'
    // 异步加载图片依赖
    implementation 'com.squareup.picasso:picasso:2.5.2'
    // 上拉刷新、下来加载依赖
    implementation 'com.scwang.smartrefresh:SmartRefreshLayout:1.1.3'
    // --  Android:视频播放器dkplayer
    //# 必选，内部默认使用系统mediaplayer进行解码
    implementation 'com.github.dueeeke.dkplayer:dkplayer-java:3.2.6'
    //# 可选，包含StandardVideoController的实现
    implementation 'com.github.dueeeke.dkplayer:dkplayer-ui:3.2.6'
    //# 可选，使用exoplayer进行解码
    implementation 'com.github.dueeeke.dkplayer:player-exo:3.2.6'
    //# 可选，使用ijkplayer进行解码
    implementation 'com.github.dueeeke.dkplayer:player-ijk:3.2.6'
    //# 可选，如需要缓存或者抖音预加载功能请引入此库
    implementation 'com.github.dueeeke.dkplayer:videocache:3.2.6'

        android:layout_width="match_parent"
        android:layout_height="match_parent"/>


</com.scwang.smartrefresh.layout.SmartRefreshLayout>

item_video_layout.xml
