项目用到城市选择，就找了一个大神的代码，自己做了修改后使用的，本程序有两个地方不是很完美：
一、点击popupWindow空白的区域不能关闭popupWindow;
二、选择器那里，不是当前选中的值，不能做到类似IOS里面的折叠，就是类似滚轮的那种立体效果。
望路过的大神们可以加以完善下。
上代码：popup_select_city.xml

使用者只要实现 citiyselectListener接口，即可监听“完成”按钮事件 并获取当前选中的值：
Select_City select_city=new Select_City(getContext(),contentView);
select_city=select_city.builder();
select_city.setListener(listener);
select_city.show();
