RecyclerViewAdapter回收其观点，因此非常期待这种行为。

当我阅读您的代码时，我发现您编写的if语句没有else，如：

        if (!TextUtils.isEmpty(response.getRoomNo()))
            holder.locationEven.setText(response.getRoomNo());

        if (!TextUtils.isEmpty(response.getSubject()))
            holder.subjectEven.setText(response.getSubject());

如果新加载的视图之前的位置中的视图不符合if语句，则会重复使用这些视图。

尝试将else添加到您的每个if语句中。添加else我的意思是添加类似

的内容 
else {
    holder.locationEven.setText("");
}

// OR

else {
    holder.locationEven.setVisibility(View.GONE);
}
