我有活动包含父multirow recyclerView在每个元素（问题，儿童recyclerView中的答案）中都有这样的tow属性
我的问题在这里，我怎样才能处理每个儿童回收商的选择，直到用户滚动recyclelerView时没有删除或重复
这是我的onBindViewHolder代码：
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
// get objects
final FollowQuestionModel item = data.get(position);
if (item != null) {
switch (item.getType()) {
case SINGLE_TYPE:
((SingleViewHolder) holder).tvSingleChoice.setText(item.getSingleChoiceModel().get(position).getQuestion());
((SingleViewHolder) holder).rvSingleChoice.setLayoutManager(new GridLayoutManager(context , 2));
SingleAnswersElementAdapter singleAdapter = new SingleAnswersElementAdapter(context, item.getSingleChoiceModel().get(position).getAnswers()
, R.layout.item_single_choice_element);
((SingleViewHolder) holder).rvSingleChoice.setAdapter(singleAdapter);
break;
case MULTI_TYPE:
((MultiViewHolder) holder).tvMultiChoice.setText(item.getSingleChoiceModel().get(position).getQuestion());
((MultiViewHolder) holder).rvMulitChoice.setLayoutManager(new GridLayoutManager(context , 2));
MultiAnswersElementAdapter multiAdapter = new MultiAnswersElementAdapter(context, item.getMultiChoiceModel().get(position).getAnswers()
, R.layout.item_multi_choice_element);
((MultiViewHolder) holder).rvMulitChoice.setAdapter(multiAdapter);
break;
case TEXT_TYPE:
((TextViewHolder) holder).tvTextQuestion.setText(item.getTextChoiceModel().get(position).getQuestion().get(position).getQuestion());
break;
}
}
}
谢谢
