RecyclerView Adapter中的ProgressBar没有刷新

Question

我面临与progressBar.setProgress()和的问题progressBar.setMax()。

我有两个项目，通常需要像附加的屏幕截图一样显示视频的进度。仅对于第一个项目，在设置了进度之后，我有一些进度数据，我需要将第二个项目的进度设置为0（零）。但是第二项ProgressBar不会重置为零，而是显示为第一项的进度长度。

我在这里打印了Items的值：

// Item1
Media List total Duration : 84063
Media List total ProgressDuration : 19380
// Item2
Media List total Duration : 0
Media List total ProgressDuration : 0

适配器代码：

class ViewHolder extends RecyclerView.ViewHolder {
    TextView fileName;
    ImageView ivThumbNail;
    ProgressBar progressBar;
    View mainContainer;
    View view;

    ViewHolder(View itemView) {
        super(itemView);
        view = itemView;
        mainContainer = itemView.findViewById(R.id.main_container);
        fileName = (TextView) itemView.findViewById(R.id.tv_file_name);
        ivThumbNail = (ImageView) itemView.findViewById(R.id.iv_thumbnail);
        progressBar = (ProgressBar) itemView.findViewById(R.id.progress_bar);
    }
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(context).inflate(R.layout.media_row, parent, false);
    return new ViewHolder(itemView);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    final Media media = mediaList.get(position);

    String videoUrl = media.video_url;

    int totalDuration = VideoPositionVo.getTotalDuration(context, videoUrl, media.course_id);
    int progressDuration = VideoPositionVo.getResumedPosition(context, videoUrl, media.course_id);

    Log.d("Media List total Duration : " , totalDuration);
    Log.d("Media List total ProgressDuration : " , progressDuration);

    holder.progressBar.invalidate();
    holder.progressBar.setMax(totalDuration);
    holder.progressBar.setProgress(progressDuration);


    String sampleThumbNail = "https://i.vimeocdn.com/video/23566238_100x75.webp";
    aQuery.id(holder.ivThumbNail).image(sampleThumbNail, true, true, imageWidth, 0);
    holder.fileName.setText(media.video_label);

}

Answer 1

在onBindViewHolder()表演中holder.progressBar.getProgressDrawable().mutate()。
