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";
}

Utils.java

package com.chy.permission;import android.view.View;
import android.view.ViewParent;
import android.widget.FrameLayout;import com.dueeeke.videoplayer.player.VideoView;
import com.dueeeke.videoplayer.player.VideoViewConfig;
import com.dueeeke.videoplayer.player.VideoViewManager;import java.lang.reflect.Field;public final class Utils {private Utils() {}/*** 获取当前的播放核心*/public static Object getCurrentPlayerFactory() {VideoViewConfig config = VideoViewManager.getConfig();Object playerFactory = null;try {Field mPlayerFactoryField = config.getClass().getDeclaredField("mPlayerFactory");mPlayerFactoryField.setAccessible(true);playerFactory = mPlayerFactoryField.get(config);} catch (Exception e) {e.printStackTrace();}return playerFactory;}/*** 将View从父控件中移除*/public static void removeViewFormParent(View v) {if (v == null) return;ViewParent parent = v.getParent();if (parent instanceof FrameLayout) {((FrameLayout) parent).removeView(v);}}/*** Returns a string containing player state debugging information.*/public static String playState2str(int state) {String playStateString;switch (state) {default:case VideoView.STATE_IDLE:playStateString = "idle";break;case VideoView.STATE_PREPARING:playStateString = "preparing";break;case VideoView.STATE_PREPARED:playStateString = "prepared";break;case VideoView.STATE_PLAYING:playStateString = "playing";break;case VideoView.STATE_PAUSED:playStateString = "pause";break;case VideoView.STATE_BUFFERING:playStateString = "buffering";break;case VideoView.STATE_BUFFERED:playStateString = "buffered";break;case VideoView.STATE_PLAYBACK_COMPLETED:playStateString = "playback completed";break;case VideoView.STATE_ERROR:playStateString = "error";break;}return String.format("playState: %s", playStateString);}/*** Returns a string containing player state debugging information.*/public static String playerState2str(int state) {String playerStateString;switch (state) {default:case VideoView.PLAYER_NORMAL:playerStateString = "normal";break;case VideoView.PLAYER_FULL_SCREEN:playerStateString = "full screen";break;case VideoView.PLAYER_TINY_SCREEN:playerStateString = "tiny screen";break;}return String.format("playerState: %s", playerStateString);}}

VideoAdapter.java

package com.chy.demoprj.adapter;import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;
import android.widget.ImageView;

import com.dueeeke.videocontroller.component.PrepareView;
import com.squareup.picasso.Picasso;import java.util.HashMap;
import java.util.List;public class VideoAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {private Context context;private List<HashMap<String,String>> datas;private OnItemChildClickListener mOnItemChildClickListener;// 播放控件点击事件/*** 构造函数* */public VideoAdapter(Context context,List<HashMap<String,String>> datas){this.context = context;this.datas = datas;}@NonNull@Overridepublic RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent,int viewType) {View view = LayoutInflater.from(context).inflate(R.layout.item_video_layout,parent,false);ViewHolder viewHolder = new ViewHolder(view);return viewHolder;}@Overridepublic void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder,int position) {ViewHolder vh = (ViewHolder) holder;HashMap<String,String> entity = datas.get(position);// 设置播放占位图（不设置默认黑色）Picasso.with(context).load(entity.get("thumbUrl")).into(vh.mThumb);vh.mPosition = position;}@Overridepublic int getItemCount() {return datas.size();}public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{public FrameLayout mPlayerContainer;// 容器public PrepareView mPrepareView;// 播放视图public ImageView mThumb;// 缩略图public int mPosition;// 当前视图indexpublic ViewHolder(@NonNull View itemView) {super(itemView);mPlayerContainer = itemView.findViewById(R.id.player_container);mPrepareView = itemView.findViewById(R.id.prepare_view);mThumb = mPrepareView.findViewById(R.id.thumb);/*** 添加点击事件* */if (mOnItemChildClickListener != null) {mPlayerContainer.setOnClickListener(this);}//通过tag将ViewHolder和itemView绑定itemView.setTag(this);}@Overridepublic void onClick(View v) {if (v.getId() == R.id.player_container){if (mOnItemChildClickListener != null){mOnItemChildClickListener.onItemChildClick(mPosition);}}}}/*** 点击事件接口* */public interface OnItemChildClickListener{void onItemChildClick(int position);}/*** 点击事件回调函数* */public void setOnItemChildClickListener(OnItemChildClickListener onItemChildClickListener) {mOnItemChildClickListener = onItemChildClickListener;}}

三、布局

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<com.scwang.smartrefresh.layout.SmartRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/refreshLayout"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><androidx.recyclerview.widget.RecyclerViewandroid: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"><FrameLayoutandroid:id="@+id/player_container"android:layout_width="match_parent"android:layout_height="187dp"android:layout_marginTop="8dp"android:background="@android:color/black"app:layout_constraintDimensionRatio="16:9"app:layout_constraintTop_toTopOf="parent"><com.dueeeke.videocontroller.component.PrepareViewandroid:id="@+id/prepare_view"android:layout_width="match_parent"android:layout_height="match_parent" /></FrameLayout></LinearLayout>
