Java 来自logcat控制台的未知错误

我制作了一个从手机存储器中获取/显示视频的应用程序。单击此按钮可进入显示手机存储器中视频的活动

当它从我的IDE启动后第一次单击时，它会打开活动，但当你退出应用程序并稍后返回并再次单击按钮时，它会崩溃。我有下面写的logcat错误。我不知道发生了什么事。如果你们能帮助我，我会很高兴的

先谢谢你

这是我的RecyclerView适配器

public class VideoAdapter extends RecyclerView.Adapter<VideoAdapter.ViewHolder> {

private Context context;
private ArrayList<VideoModel> videoModels;

public VideoAdapter(Context context, ArrayList<VideoModel> videoModels) {
    this.context = context;
    this.videoModels = videoModels;
}

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

@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
    final VideoModel vidModel = videoModels.get(position);

    Glide.with(context).load(vidModel.getData()).into(holder.video_thumb);
    holder.duration.setText(vidModel.getDuration());

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (vidModel.getData() != null){
                Intent intent = new Intent(context, SelectedVideoActivity.class);
                intent.putExtra("videoURL", vidModel.getId());
                context.startActivity(intent);
            }else {
                Toast.makeText(context, "Invalid video", Toast.LENGTH_SHORT).show();
            }

        }
    });

}

@Override
public int getItemCount() {
    return videoModels.size();
}

static class ViewHolder extends RecyclerView.ViewHolder {
    ImageView video_thumb;
    TextView duration;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);

        video_thumb = itemView.findViewById(R.id.video_thumb);
        duration = itemView.findViewById(R.id.duration);

    }
}

从您的错误日志
com.example.oqpyd，PID:15872 java.lang.IndexOutOfBoundsException:检测到不一致。视图保持架适配器位置无效视图保持架{f7adb0f position=23 id=-1）

---

如果你看一下这两行，我希望你能找到你的错误，你的视图持有者试图将无效视图保持在位置23。

我认为错误是明显的IndexOutOfBoundsException在你的Adapter Hi Cliff！谢谢你的回答，但仍然卡住了，我已经更新了我的问题。请检查它。@JimmyWire我认为这个错误正在刷新数据当您再次输入并按下按钮时，将显示全新内容。您可以使用notifyItemRangeRemoved（0，previousContentSize）轻松修改内容以满足您的需要；如果我的答案解决了您的问题，并且您认为有帮助，请将其标记为已接受。祝您的应用程序好运。
