Question

我的任务是在recyclerview中执行父和子Checkbox，就像有4个州，所有州都有少数城市。**现在的问题是当我检查父（州）但正确的城市没有被选中时。说古吉拉特邦有surat，艾哈迈达巴德城市，但是当我们选择古吉拉特邦复选框时，它会在其他州的儿童玛哈特城市中选择所有城市**。

这是一个代码（此代码在主自定义适配器中）：

public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        itemview = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_row, parent, false);
        MyViewHolder myViewHolder = new MyViewHolder(itemview);


        return myViewHolder;
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {
        dynamiclist1();
        final Employee emp = list.get(position);

        holder.setIsRecyclable(false);
        holder.tv.setText(emp.getName());
        if (emp.getName() == "Gujarat") {
            holder.chkbox_parent.setTag("Gujarat");

        }
        holder.rv.setHasFixedSize(true);

        LinearLayoutManager llm = new LinearLayoutManager(context);
        holder.rv.setLayoutManager(llm);
        holder.rv.setHasFixedSize(true);
        holder.chkbox_parent.setTag(emp.getName());
        if (emp.getName() == "Gujarat") {
            cuChild = new CustomAdapter_child(context, child1, "Gujarat");
        } else {
            cuChild = new CustomAdapter_child(context, child1, "");

        }
        holder.rv.setAdapter(cuChild);
        holder.chkbox_parent.setTag(emp.getName());
        holder.chkbox_parent.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                Toast.makeText(context, "" + holder.chkbox_parent.getTag(), Toast.LENGTH_SHORT).show();
                try {
                    RecyclerView rv1 = (RecyclerView) itemview.findViewById(R.id.rv2);
                    Toast.makeText(context, "" + rv1.getChildCount(), Toast.LENGTH_SHORT).show();
                    CheckBox cb;
                    TextView txt;
                    for (int i = 0; i < rv1.getChildCount(); i++) {



                        cb = (CheckBox) rv1.getChildAt(i).findViewById(R.id.chkbox_child);
                        //txt = (TextView) rv1.getChildAt(i).findViewById(R.id.tv2);
                        Toast.makeText(context, "" + cb.getText(), Toast.LENGTH_SHORT).show();

                            cb.setChecked(holder.chkbox_parent.isChecked());

                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });


    }

（这是子自定义适配器）：

public void onBindViewHolder(MyViewHolder holder, int position) {

        Employee_Child emp = list.get(position);
        holder.tv.setText(emp.getName1().concat("-").concat(this.TAG ).concat(""+position));

        if (this.TAG == "Gujarat") {
            holder.chkchild.setText("Gujarat");
        }

  }

在“父级和子级”复选框中选择所有问题
