java - android 单选题 listview嵌套 listview。

我有个做选择题的需求，界面样式如下图

我通过listview嵌套listview来实现，子listview的item是一个实现

我的父listview的item如下，设置了listview的android:choiceMode="singleChoice"

子listview的item如下，其中CheckableLinearLayout是实现重写Linearlayout实现Checkable接口的自定义View
xml：

CheckableLinearLayout：

public class CheckableLinearLayout extends LinearLayout implements Checkable{
    public boolean mChecked = false;
    public CheckableLinearLayout(Context context, AttributeSet attrs,
                                int defStyle) {
        super(context, attrs, defStyle);
    }

    public CheckableLinearLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CheckableLinearLayout(Context context) {
        super(context);
    }

    @Override
    public void setChecked(boolean checked) {
        if (mChecked != checked) {
            mChecked = checked;
            refreshDrawableState();
            for (int i = 0, len = getChildCount(); i < len; i++) {
                View child = getChildAt(i);
                if(child instanceof Checkable){
                    ((Checkable) child).setChecked(checked);
                }
            }
        }
    }

    @Override
    public boolean isChecked() {
        return mChecked;
    }

    @Override
    public void toggle() {
        setChecked(!mChecked);
    }
}

父Adapter：

  @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.assess_parent_list_item, parent, false);
            holder = new ViewHolder(convertView);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.tvParentName.setText(key.get(position));
        //innerlistview 的adapter
        List ratingLists = map.get(key.get(position));
        AssessChildAdapter adapter = new AssessChildAdapter(ratingLists, mContext);
        holder.lvInner.setAdapter(adapter);
        int pos=holder.lvInner.getCheckedItemPosition();
        MLog.e(pos);
        if(pos==-1){
            holder.lvInner.setItemChecked(0, true);
        }else{
            holder.lvInner.setItemChecked(holder.lvInner.getCheckedItemPosition(),true);
        }

        int selectedPos=holder.lvInner.getCheckedItemPosition();
        setSelected(selectedPos,ratingLists.get(selectedPos));

        //根据innerlistview的高度机损parentlistview item的高度
        setListViewHeightBasedOnChildren(holder.lvInner);

        return convertView;
    }
    

子Adapter:

 @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder = null;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.assess_child_list_item, parent, false);
            viewHolder = new ViewHolder(convertView);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }
        viewHolder.tvChildName.setText(ratingLists.get(position).getDescription());
        viewHolder.tvChildScore.setText(ratingLists.get(position).getScore() + "");

        return convertView;
    }
        

希望有人帮忙看下，万分感谢
