在expandableListView的第三层填充不同的数组

public class MyExpandableListAdapter extends BaseExpandableListAdapter {
    private Context context;
    private List<String> groups;
    private Map<String, List<String>> children;

    public MyExpandableListAdapter(Context context, List<String> groups, Map<String, List<String>> children) {
        this.context = context;
        this.groups = groups;
        this.children = children;
    }

    @Override
    public int getGroupCount() {
        return groups.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        String group = groups.get(groupPosition);
        return children.get(group).size();
    }

    @Override
    public Object getGroup(int groupPosition) {
        return groups.get(groupPosition);
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        String group = groups.get(groupPosition);
        return children.get(group).get(childPosition);
    }

    @Override
    public long getGroupId(int groupPosition) {
        return groupPosition;
    }

    @Override
    public long getChildId(int groupPosition, int childPosition) {
        return childPosition;
    }

    @Override
    public boolean hasStableIds() {
        return true;
    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
        // 设置分组的视图
        // 可以使用convertView进行复用优化
        // 返回分组的视图
    }

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
        // 设置子项的视图
        // 可以使用convertView进行复用优化
        // 根据groupPosition和childPosition获取要填充的数组
        // 返回子项的视图
    }

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return true;
    }
}
