这种RecyclerView嵌套RecyclerView,子RV的item设置了默认的值,然后滑动复用后不显示了,有什么好的解决方法?

[202005021116]

最好是伪代码或者代码可以提供一下,大致思路知道,就是这块代码不知道怎么写,
1.UI图:

2.父RV的item点击:

  @Override
    public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
        EnterpriseSealBean bean = mDatas.get(position);
        bean.setExpand(bean.isExpand() ? false : true);//收缩就展开,展开就收缩
        mAdapter.notifyItemChanged(position);
    }

3.adapter类,里面包含子RV的item点击

public class EnterpriseSealAdapter extends BaseQuickAdapter<EnterpriseSealBean, BaseViewHolder> {

    private BottomSheetDialog mDialog;

    public EnterpriseSealAdapter(int layoutResId, @Nullable List<EnterpriseSealBean> data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, EnterpriseSealBean item) {
        helper.addOnClickListener(R.id.rv_content);
        RecyclerView recyclerView = helper.getView(R.id.rv_content);

        boolean expand = item.isExpand();
        if (expand) {
            recyclerView.setVisibility(View.VISIBLE);
        } else {
            recyclerView.setVisibility(View.GONE);
        }

        List<SealImageBean> data = new ArrayList<>();
        for (int i = 0; i < 5; i++) {
            SealImageBean bean = new SealImageBean();
            data.add(bean);
        }
        EnterpriseSealImageAdapter adapter = new EnterpriseSealImageAdapter(R.layout.item_enterprise_seal_image, data);
        GridLayoutManager manager = new GridLayoutManager(mContext, 2);
        recyclerView.setLayoutManager(manager);
//        recyclerView.setNestedScrollingEnabled(false);
//        recyclerView.setFocusableInTouchMode(false);
//        recyclerView.requestFocus();
        recyclerView.setAdapter(adapter);
        //子RV的item点击
        adapter.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
                Toast.makeText(mContext, "点击" + position, Toast.LENGTH_SHORT).show();
                for (int i = 0; i < data.size(); i++) {
                    if (i != position) {
                        data.get(i).setDefault(false);//未选中
                    } else {
                        data.get(position).setDefault(true);//选中默认
                    }
                }
                adapter.notifyDataSetChanged();
            }
        });
    }
}

BaseRecyclerViewAdapterHelper不是有个BaseMultiItemQuickAdapter吗

你里面的RecyclerView Adapter的代码发来。 猜测是你把默认设置gone了没有设置过visible，复用的东西if之后必须要有else

麻烦帮我看一下

public class EnterpriseSealImageAdapter extends BaseQuickAdapter<SealImageBean, BaseViewHolder> {

    public EnterpriseSealImageAdapter(int layoutResId, @Nullable List<SealImageBean> data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, SealImageBean item) {
        TextView view = helper.getView(R.id.tv_seal_status);
        boolean aDefault = item.isDefault();
        if (aDefault) {
            view.setVisibility(View.VISIBLE);//设为了默认
            item.setDefault(true);
        } else {
            view.setVisibility(View.GONE);
            item.setDefault(false);
        }
    }
}

又看了一遍，你的data搞错了，复用时每次都new出来肯定是选了也白选：

 List<SealImageBean> data = new ArrayList<>();
        for (int i = 0; i < 5; i++) {
            SealImageBean bean = new SealImageBean();
            data.add(bean);
        }

你在EnterpriseSealBean里面加一个

class EnterpriseSealBean {
    public List<SealImageBean> childData = new ArrayList<>();
}

然后在Activity或者那个执行一遍的地方造出数据 然后初始化里面adapter的地方改成item.childData：

EnterpriseSealImageAdapter adapter = new EnterpriseSealImageAdapter(R.layout.item_enterprise_seal_image, item.childData);

谢谢,确实是这个问题引起的,自己粗心大意了
