在做一个项目的时候需要选择商品的规格，在参考了一些相似功能的实现之后，自己结合项目需求自定义了一个弹窗。下面是实现该功能的截图 及 相关代码。

1、实现这个功能主要用了流式布局FlowTagLayout 来展示规格 

参照我的一篇文章 点击打开链接

2、弹窗布局 pop_categary_chose.xml

3、新建dialog弹窗 设置布局 初始化各个控件

int goodsCount = 1;
int specId = 0;
private String desc1 = "", desc2 = "", defaultDesc = "";
private int realStock = 0;
private TagAdapter<TagBean> mSizeTagAdapter1, mSizeTagAdapter2;
private ArrayList<ArrayList<TagBean>> spceList = new ArrayList<>();//所有的二级规格列表的集合
private ArrayList<TagBean> listDesc1 = new ArrayList<>();//一级规格列表
private ArrayList<TagBean> listDesc2 = new ArrayList<>();//选中的一级规格对应的二级规格列表
private AlertDialog dialog; 
List<String> data1 = new ArrayList<>();//第一规格名称

private void showCatePopupWindow(View view) {
        dialog = new AlertDialog.Builder(this).create();//生成一个AlertDialog对象
        dialog.show();//调用AlertDialog的show()方法显示
        dialog.setCanceledOnTouchOutside(true);
        View contentView = null;
        // 一个自定义的布局，作为显示的内容
        contentView = LayoutInflater.from(this).inflate(
                R.layout.pop_categary_chose, null);
        final TextView tvDescTip = (TextView) contentView.findViewById(R.id.tv_desc_tip);

        FlowTagLayout flowLayout1 = (FlowTagLayout) contentView.findViewById(R.id.fl_desc1);
        final FlowTagLayout flowLayout2 = (FlowTagLayout) contentView.findViewById(R.id.fl_desc2);
        TextView tvReduce = (TextView) contentView.findViewById(R.id.tv_reduce);

        llSize2 = (LinearLayout) contentView.findViewById(R.id.ll_size2);
        Window window = dialog.getWindow();//获取当前的Window对象，然后下面进行窗口属性的设置
        window.setContentView(contentView);//加载布局，view是填充自定义菜单布局xml 得到的
        window.setBackgroundDrawableResource(android.R.color.transparent);//这个很重要，将背景设为透明
        window.setGravity(Gravity.BOTTOM);//这个也很重要，将弹出菜单的位置设置为底部
        window.setWindowAnimations(R.style.dialog_style);//菜单进入和退出屏幕的动画，实现了上下滑动的动画效果
        window.setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);//设置菜单的尺寸
        data1.clear();
        listDesc1.clear();//一级规格列表
