Android ProvinceDistrict菜单，android 省市区县三级联动菜单，在弹出的选择框中，支持内容列表滚动。盛市、县菜单内容事前存储在文件中，结合JSON当用户选择时，从assert文件夹中读取省市区的json文件，然后转化为json对象，加载对应的区县内容，完成后释放Json对象的内存，实现的步骤： 　　把全国的省市区的信息以json的格式保存，解析完成后赋值为null 　　设置，省，市，县，的适配器，进行动态设置其中的值 begin 　　设置控件点击选择监听 　　根据当前的省，更新市和地区信息，第三个地址是详细地址，并且是第一次设置edtext值，正好，地址的长度为3的时候，设置详细地址。 　　不懂的地方，可参见本源码中的注释，非常丰富。

ListView头图片下拉放大效果在屏幕上按住下拉可以实现图片的放大，类似的效果可以在手机版的QQ空间看到，不过我没有想出这个例子图片放大可以应用的具体场景。(Listview head picture drop-down amplification effect in the screen hold down to achieve the picture enlarged. Similar effects can be seen in the mobile phone version of the QQ space, but I do not think this example picture amplification can be applied to the specific scene.)
