这是我的行，我收到此崩溃这是我的onBindViewHolder方法

 request = GlideApp.with(context)
            .asDrawable()

            .centerCrop()
            .override(reqWidth, reqWidth)
            .transition(withNoTransition());

  @Override
public void onBindViewHolder(final CustomViewHolder holder, int position) {
    Utilities.setMaxLines(holder.img_label);


    Log.i("times", "times");

    AlbumClass item = list.get(position);
    if (item.getType() == Utilities.TYPE_VIDEOS) {
        if (item.bitmap != null)
            holder.gallery_img.setImageBitmap(item.bitmap);
    } else {

        Uri uri = Uri.fromFile(new File(item.getFilePath()));

        request.load(uri).into(holder.gallery_img);
    }
    //holder.gallery_img.setImageBitmap(Utilities.getImageBitmap(type, mContext, item.getFirstChildId()));
    holder.img_label.setText(item.getName());
    holder.count.setText(String.valueOf(item.getCount()));


}

有人可以帮助为什么会这样吗？
