Android JzvdStd视频播放

• 效果如下
  1.添加网路权限

    <uses-permission android:name="android.permission.INTERNET" />

2.导入依赖

    implementation 'cn.jzvd:jiaozivideoplayer:7.0.5'
    implementation 'com.github.bumptech.glide:glide:4.8.0'
    implementation 'com.android.support:recyclerview-v7:30.0.0'

3.item_video_page.xml页面

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <cn.jzvd.JzvdStd
        android:id="@+id/jz_video"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

4.VideoPageAdapter类

public class VideoPageAdapter extends RecyclerView.Adapter<VideoPageAdapter.VideoViewHolder> {
    private Context context;
    private List<String> list;

    public VideoPageAdapter(Context context, List<String> list) {
        this.context = context;
        this.list = list;
    }

    @NonNull
    @Override
    public VideoViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        return new VideoViewHolder(LayoutInflater.from(context).inflate(R.layout.item_video_page,
                parent, false));
    }

    @Override
    public void onBindViewHolder(@NonNull VideoViewHolder holder, int position) {
        holder.jz_video.setUp(list.get(position), String.format("第%d个视频", position + 1),
                JzvdStd.STATE_NORMAL);
        if (position==0){
            holder.jz_video.startVideo();
        }
        Glide.with(context).load(list.get(position)).into(holder.jz_video.thumbImageView);
    }

    @Override
    public int getItemCount() {
        return Math.max(list.size(), 0);
    }


    public static class VideoViewHolder extends RecyclerView.ViewHolder {
        public JzvdStd jz_video;

        public VideoViewHolder(@NonNull View itemView) {
            super(itemView);
            jz_video = itemView.findViewById(R.id.jz_video);
        }
    }

}

5.MainActivity布局
