Android 广告机图片视频轮播

最近因为要做一个广告机上图片视频轮播，所以又是百度，github上一堆找，结果发现并没有特别合适的，不是播放视频首帧黑屏，就是切换界面后，没法继续播放，或者动态更新数据后，没法继续轮播等等问题，所以最后结合别人的方案自己修改了一下，具体参考android 实现图片和视频混合轮播_android 图片视频轮播_a1466850214的博客-CSDN博客

修改完成后，1.可以实现无黑屏
                      2.切换界面后，回到播放界面继续上次播放位置播放，
                      3.不支持点击和手动切换
                      4.动态更新数据后继续播放
下面是具体代码:
1.播放实体类（因为评论区要图片时长自定义，加了一个自定义时间）

public class Advance {
 
    public String path;//路径  我使用的是本地绝对路径
    public String type;//类型 1、视频 2、图片
    private int playSecond;//图片播放时长
    public Advance(String path, String type,int playSecond) {
        this.path = path;
        this.type = type;
        this.playSecond = playSecond;
    }

    public int getPlaySecond() {
        return playSecond;
    }

    public void setPlaySecond(int playSecond) {
        this.playSecond = playSecond;
    }
}

2.图片类

package com.anssy.smartbox.selfview.videoplay;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;
import android.widget.RelativeLayout;

import com.anssy.smartbox.utils.glide.GlideApp;

public class AdvanceImageView extends RelativeLayout {
    private ImageView imageView;
 
    public AdvanceImageView(Context context) {
        super(context);
        initView();
    }
 
    public AdvanceImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView();
    }
 
    public AdvanceImageView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initView();
    }
 
 
    private void initView() {
        imageView = new ImageView(getContext());
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        addView(imageView, new RelativeLayout.LayoutParams(-1, -1));
    }
 
    public void setImage(String path) {
        GlideApp.with(getContext()).load(path).into(imageView);
    }
 
}

3.视频播放类，这里面的播放视频控件，没有采用和其他博主用的系统VideoView,这里引用一个第三方，大家可以在gradle里面导入，至于为什么引入第三方，1.可以实现缓存2.视频pause后，切回后，可以无缝播放，Application中加入初始化，如果有视频播放不了，请切换内核为AndroidMediaFactory.create()或切换为ExoPlayer，具体参考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

        VideoViewManager.setConfig(VideoViewConfig.newBuilder()
                //使用使用IjkPlayer解码
                .setPlayerFactory(IjkPlayerFactory.create())
                .build());

6.ViewPager的适配器，里面原作者的代码我并未删除，大家也可以对比下，或者区别调用下，看下效果，我将原作者的thread定时器，改为了handler的方法，这样可操作性要强一点，避免动态切换数据后，轮播卡死的情况。这里我用的是自己定义的handler,大家替换为系统的handler即可

7.xml中引入

  <com.anssy.smartbox.selfview.videoplay.AdvanceView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/home_vp"
            android:clickable="false"
            />

8.activity中调用,oncreate中调用initData()即可，动态更新数据，只需调用data.clear(),mViewPager.setData(data)即可

    private List<Advance> data = new ArrayList<>();   
    private void initView(){
     mViewPager = findViewById(R.id.home_vp);
        mViewPager.setOnTouchListener(new View.OnTouchListener() {

                return true;
            }
        });
    }  
        
        private void initData(){
         data.clear();
        //https://t7.baidu.com/it/u=1956604245,3662848045&fm=193&f=GIF

        data.add(advance3);
        mViewPager.setData(data);
    }

    
    public static String toURLString(String str) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < str.length(); i++) {
            char charAt = str.charAt(i);
            if (charAt > 255) {
                try {

        return sb.toString();
    }


    @Override

        super.onResume();
        mViewPager.setResume();

    }

    @Override

9.播放效果
 

切换效果

源码下载地址(不建议下载):https://download.csdn.net/download/hardWork_yulu/87814212

看到很多小伙伴下载了源码，实在不忍心小伙伴使用HttpUrlConnection来进行网络请求，其实我在实际使用中也发现原有缓存存在一些不确定的问题，加上AndroidCache停止维护很久，所以我一直在寻找可替代的缓存框架，最后在GitHub - JeffMony/JeffVideoCache: Better than AndroidVideoCache, it supports M3U8 and MP4中使用作者的Cache框架，可使用okhttp，没有使用播放器，整合了一下。已将2.0视频轮播代码上传，感兴趣的小伙伴可以下载：https://download.csdn.net/download/hardWork_yulu/88059783
和1.0一样，一样下载在APP私有目录下，无需请求读写权限

效果图:

记得配置忽略http的xml文件,不然有的视频不能访问

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true"/>
</network-security-config>
