我有一个父级回收站视图，其中包含一个水平回收站视图作为其项目。我在其中显示类别明智的视频。 当我开始滚动水平回收视图时，应用程序崩溃。
错误是：

答案 0 :(得分：0)
如果不能正常工作，您可以尝试以下水平适配器，尝试垂直适配器：
@Override
public void onBindViewHolder(final Category_thumbnail.MyViewHolder holder, int position) {
//check this line
if (position < 0 || position >= vidList.size()) return;
holder.loader_small.setVisibility(View.VISIBLE);
holder.vtitle.setText(vidList.get(position).get("vtitle"));
holder.views.setText(vidList.get(position).get("vviews"));
holder.duration.setText(vidList.get(position).get("vtime"));
Picasso.with(context).load(vidList.get(position).get("vimage").toString()).into(holder.thumbnail, new Callback() {
@Override
public void onSuccess() {
holder.loader_small.setVisibility(View.GONE);
}
@Override
public void onError() {
}
});
}
@Override
public int getItemCount() {
//check this line
return (vidList != null) ? vidList.size() : 0;
}
