树状列表有bug，数据会自动添加

[love-aqua]

public class QuickExpandableAdapter extends BaseMultiItemQuickAdapter<MultiItemEntity, BaseViewHolder> { public static final int TYPE_LEVEL_0 = 0; public static final int TYPE_LEVEL_1 = 1;

/**
 * Same as QuickAdapter#QuickAdapter(Context,int) but with

    super(data);
    addItemType(TYPE_LEVEL_0, R.layout.view_expand_0);

    switch (helper.getItemViewType()){
        case TYPE_LEVEL_0:
            final TitleExpandItem item0 = (TitleExpandItem) item;
            helper.setText(R.id.expand_list_item0_tv,item0.getTitle());
            helper.itemView.setOnClickListener(new View.OnClickListener() {
                @Override

                    if (item0.isExpanded()){
                        collapse(pos);

// ToastUtils.showTastyInfo("收起：" + item0.getTitle()); }else { expand(pos); // ToastUtils.showTastyInfo("展开：" + item0.getTitle()); } } }); break; case TYPE_LEVEL_1: int parentPosition = getParentPosition(item); TitleExpandItem titleExpandItem = (TitleExpandItem) getData().get(parentPosition); RecyclerView recyclerView = helper.getView(R.id.expand_list_item1_tv); BaseQuickAdapter baseQuickAdapter = new BaseQuickAdapter<PopItemModel,BaseViewHolder>(R.layout.grid_item,titleExpandItem.getSubItems()) { @Override protected void convert(BaseViewHolder helper, PopItemModel item) { TextView tv_title = helper.getView(R.id.tv_title); tv_title.setText(item.item); helper.addOnClickListener(R.id.tv_title); if (item.isSelect){ tv_title.setBackgroundResource(R.drawable.text_bg3); }else{ tv_title.setBackgroundResource(R.drawable.text_bg2); } } }; recyclerView.setLayoutManager(new GridLayoutManager(mContext,3)); recyclerView.setAdapter(baseQuickAdapter);

            baseQuickAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
                @Override
                public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
                    //改变选中的值

// if (R.id.tv_title == view.getId()){ // for (int i = 0; i < item1.list.size(); i++) { // if (position == i){ // item1.list.get(i).isSelect = true; // }else{ // item1.list.get(i).isSelect = false; // } // } // } // baseQuickAdapter.notifyDataSetChanged(); } }); break; } } }

我adapter如上，但是当点击一个数据的时候，本来是这样的数据结构的。 点击后，数据自己变成这样了。 请问是怎么回事啊？我调试了好久都没找到问题，而且我根本没改变过数据。数据结构在点击就变了。

我在子项EditText输入内容，下拉后面每隔几个子项也会添加这个内容。数据错乱

editText的输入被复用，数据的绑定要基于Model层，不在直接在view层处理数据的记录

还是搞不掂这个问题，不知道为啥会列表自动添加这些数据？
