ProgressBar在RecyclerView適配器中不令人耳目一新

Question

我遇到了progressBar.setProgress()和progressBar.setMax()的問題。

我有兩個項目，通常需要顯示視頻的進展，就像附加的屏幕截圖一樣。對於第一個項目，只有我設置了進度數據後，我需要爲第二個項目設置進度爲0（零）。但是第二項ProgressBar未被重置爲零而不是它仍然顯示第一項的進度長度。

我打印的值項目在這裏：

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

適配器代碼：

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()執行holder.progressBar.getProgressDrawable().mutate()。
