仅适用于 Android 7 和 8 - ClassCastException：无法将 LayoutParams 转换为 AbsListView$LayoutParams

我正在研究一个非常奇怪的问题。我没有编写原始代码，但我正在调查为什么它现在突然崩溃。看完之后，我没有发现任何崩溃的原因。此外，它可以在较低的操作系统级别（例如 Android 6）中完美运行；然而，在 Android 7 和 8 中运行时，它始终崩溃。一开始也很难重现，因为崩溃仅在第 6 个索引之后才会显现......最初认为这可能是一些损坏的数据，因为问题只是针对某些用户表现出来。但一旦我增加了列表中的项目数量，我就能够一致地重现。当我们迭代药物对象列表并构造它们的列表以供用户快速引用时，列表适配器中会发生类转换异常。索引 0 到 5 没有问题；然而，在处理完索引6之后，应用程序在返回View（最初传入的convertView）时崩溃。我已经使用多达 6 种药物逐步执行了代码，但从未发现任何问题。在逐步执行第 6 个索引（第 7 个药物）后，当 getView(...) 方法返回时，它会始终崩溃。正如我之前所说，只有当代码在 Android 7 和 8 中运行时才会发生这种情况。当代码在 Android 6 上运行时（例如），它可以处理 10 多种药物甚至更多。甚至对拥有 20 个用户的用户进行了测试。想知道是否有人遇到过此问题和/或有建议/想法。 Android 7 和 8 中适配器的视图回收器是否可能发生某些变化？仅当药物列表大于屏幕可显示时才会发生这种情况，这是没有意义的。就好像回收器在 Android 7 和 8 中存在错误一样......

这是 getView(...) 的实现：

public View getView(int position, View convertView, ViewGroup parent) {

    Log.i(TAG, position + " | " + convertView);

    ViewHolder holder;

    LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

    // MedicationItem
    MedicationItem medItem_pos = rowItems.get(position);

    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.med_adjustment_reconciliation_item, parent, false);
        holder = new ViewHolder();
        holder.drugInfo = (TextView) convertView.findViewById(R.id.med_adj_recon_list_item_drug_info_textview);
        holder.drugDosageInfo = (TextView) convertView.findViewById(R.id.med_adj_recon_list_item_drug_dosage_info_textview);

        if (medItem_pos.isTaking()) {
            ((ListView)parent).setItemChecked(position, true);

        } else {
            ((ListView)parent).setItemChecked(position, false);
        }

        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    // Build Drug Info
    StringBuilder sbDrugInfo = new StringBuilder(medItem_pos.getDrug());
    if (StringUtils.isNotEmpty(medItem_pos.getTradeName()))
        sbDrugInfo.append(String.format(" (%s) ", Html.fromHtml(medItem_pos.getTradeName())));
    if (null != medItem_pos.getDose() && medItem_pos.getDose() > 0 && StringUtils.isNotEmpty(medItem_pos.getMedUnit())) {
        MedUnit medUnit = EnumUtils.lookup(MedUnit.class, medItem_pos.getMedUnit());
        sbDrugInfo.append(String.format("%s %s", medItem_pos.getDose(), (null==medUnit?medItem_pos.getMedUnit():medUnit.getLocaleString())));
    }

    // Build Drug Dosage Info
    StringBuilder sbDrugDosageInfo = new StringBuilder();
    sbDrugDosageInfo.append(defineQuantity(medItem_pos.getQuantity(), medItem_pos.getDosageFormUnit()));

    if (StringUtils.isNotBlank(medItem_pos.getFrequency())){
        MedFrequency medFrequency = EnumUtils.lookup(MedFrequency.class, medItem_pos.getFrequency());
        if (null != medFrequency){
            if (sbDrugDosageInfo.length() > 0)
                sbDrugDosageInfo.append(" | ").append(medFrequency.getLocaleString());
            else
                sbDrugDosageInfo.append(medFrequency.getLocaleString());
        }else{
            sbDrugDosageInfo.append(MedFrequency.OTHER.getLocaleString());
        }
    }

    // display drug information
    holder.drugInfo.setText(sbDrugInfo.toString());
    holder.drugDosageInfo.setText(sbDrugDosageInfo.toString());

    return convertView;
}

...
...

private class ViewHolder {
    TextView drugInfo;
    TextView drugDosageInfo;
}

这是错误：
