GitHub - Doikki/DKVideoPlayer: Android Video Player. 安卓视频播放器，封装MediaPlayer、ExoPlayer、IjkPlayer。模仿抖音并实现预加载，列表播放，悬浮播放，广告播放，弹幕，视频水印，视频滤镜

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'

二、工具类

Tag.java

package com.chy.permission;

/**
 * 播放器标签
 */
public final class Tag {
    //列表播放
    public static final String LIST = "list";
    //无缝播放
    public static final String SEAMLESS = "seamless";
    //画中画
    public static final String PIP = "pip";
}

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>


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

item_video_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/player_container"
        android:layout_width="match_parent"
        android:layout_height="187dp"
        android:layout_marginTop="8dp"
        android:background="@android:color/black"
